Biographies
- Kerr Roy biography
- One of his lecturers at Canterbury College was Walter Warwick Sawyer who had specialised in relativity and quantum theory when studying at St John's College, Cambridge.
- He undertook research in relativity, although he was assigned a thesis advisor with no interest in that topic [7]:-
.
- My nominal supervisor was a particle physicist who had no interest in general relativity.
- He submitted his doctoral thesis Equations of Motion in General Relativity in 1958 and published the results of the thesis in three papers entitled The Lorentz-covariant approximation method in general relativity in Nuovo Cimento in 1959.
- Before he left, Josh and I became interested in the new methods that were entering general relativity from differential geometry at that time.
- He had just persuaded the Texas state legislators to finance a Center for Relativity at the University of Texas, and had arranged for an outstanding group of relativists to join.
- In 1963, Roy Kerr, a New Zealander, found a set of solutions of the equations of general relativity that described rotating black holes.
- In my entire scientific life, extending over forty-five years, the most shattering experience has been the realization that an exact solution of Einstein's equations of general relativity, discovered by the New Zealand mathematician, Roy Kerr, provides the absolutely exact representation of untold numbers of massive black holes that populate the universe.
- Everybody who tried to solve the problem was going at it from the front, but I was trying to solve the equation from a different point of view - there were a number of new mathematical methods coming into relativity at the time and Josh [Goldberg] and I had had some success with these.
- Teddy Newman and Roger Penrose were working on a similar set of methods, but Teddy had come out with this as-yet unpublished theorem that basically 'proved' that my solution couldn't exist! Luckily, my neighbour, who was playing around with relativity, too, got hold of a preprint and I just scanned through it (I'm a lazy reader) and hit the crucial part which proved to me that my solution could exist! After that, I kept working like mad and found the solution in a few weeks.
- The Hughes Medal is awarded to Professor R P Kerr in recognition of his distinguished work on relativity, especially for his discovery of the so-called Kerr black hole.
- Professor Kerr has made other significant contributions to general relativity theory, but the discovery of the Kerr black hole was so remarkable as to compare with the discovery in physics of a new elementary particle.
- for his contribution to relativity through the Kerr metric.
- The Kerr Fest, a Symposium on Black Holes in Astrophysics, General Relativity and Quantum Gravity, was held 26 - 28, August 2004 at the University of Canterbury, Christchurch, to mark Roy Kerr's 70th birthday.
- for his fundamental contribution to Einstein's theory of general relativity: "The gravitational field of a spinning mass as an example of algebraically special metrics."
.
- Einstein biography
- Einstein's second 1905 paper proposed what is today called the special theory of relativity.
- He based his new theory on a reinterpretation of the classical principle of relativity, namely that the laws of physics had to have the same form in any frame of reference.
- Einstein was not the first to propose all the components of special theory of relativity.
- He made important contributions to quantum theory, but he sought to extend the special theory of relativity to phenomena involving acceleration.
- Einstein called his new work the general theory of relativity.
- Just before publishing this work he lectured on general relativity at Gottingen and he wrote:-
.
- In fact Hilbert submitted for publication, a week before Einstein completed his work, a paper which contains the correct field equations of general relativity.
- However he received the Barnard Medal during his visit and lectured several times on relativity.
- Einstein received the Nobel Prize in 1921 but not for relativity rather for his 1905 work on the photoelectric effect.
- In 1944 he made a contribution to the war effort by hand writing his 1905 paper on special relativity and putting it up for auction.

- Carmichael biography
- Carmichael was promoted to Associate Professor at Indiana in 1912 and in the autumn of that year he delivered a short course on the theory of relativity.
- He published On the Theory of Relativity: Analysis of the Postulates in the Physical Review in September 1912.
- This analysis of the postulates of relativity was undertaken in order to ascertain on just which of the postulates certain fundamental conclusions of the theory depend.
- Some of the conclusions of relativity have been attacked by those who admit just the parts of the postulates from which the conclusions objected to can be derived by purely logical processes.
- In November 1912 he submitted another article On the Theory of Relativity: Philosophical Aspects to the Physical Review which was published in March 1913.
- Based on these papers and his lecture course, Carmichael published a 74-page book The theory of relativity in 1913.
- It is now more than eight years since the theory of relativity was expounded by Einstein, and, although the literature of the subject is already considerable, this is practically the first presentation in book form which has been offered to English readers.
- Of course this work was on what is now called the special theory of relativity and after Einstein published the general theory of relativity, Carmichael brought out a second edition of his book in 1920.
- The theory of relativity has now reached its furthest conceivable generalisation in the direction of the covariance of the laws of nature under transformations of coordinates.
- The older theory of relativity remains valid as a special case of the general theory and may well serve as an introduction to its more far-reaching aspects.
- In May 1926 a debate on the theory of relativity was held at Indiana University and Carmichael both participated in the debate and edited the resulting volume A Debate on the Theory of Relativity (1927).
- Carmeli biography
- The significance of the "tail" and the relation to other equations of motion (1965), Motion of a charge in a gravitational field (1965), The equations of motion of slowly moving particles in the general theory of relativity (1965), and Equations of motion without infinite self-action terms in general relativity (1965).
- He carried out his research in general relativity and gravitation, and lectured in Lehigh University, Temple University and then in the University of Maryland.
- Carmeli's field included gravitation and gauge field theory, the theory of spinors as applied to physics, Einstein special and general relativity, and astrophysics.
- He developed his own cosmological relativity theory, both special and general, in which the age of Universe is postulated as constant, just as the speed of light is in Einstein's theory, and the velocity of receding galaxies is considered as a new independent variable.
- Group theory and general relativity : Representations of the Lorentz group and their applications to the gravitational field (1977):-

- devoted to the formulation of Einstein's theory of general relativity as a gauge theory with the SL(2, C) group as the gauge group;
.
- Cosmological special relativity : The large scale structure of space, time and velocity (1997):-
.
- which gives an introduction to the theory of spinors for the general physicist, not only for workers in general relativity.
- Re-envisioning Einstein's theories of Special and General Relativity and building on the work of Edwin Hubble, Dr Carmeli has suggested that the universe's expansion must be constantly accelerating, and that time is therefore relative; in other words, it can only be measured relative to the position and velocity of the measurer.
- Eddington biography
- Eddington made important contributions to the theory of general relativity.
- He lectured on relativity at the British Association meeting in 1916 and produced a major report on the topic for the Physical Society in 1918.
- Its aim was to verify the bending of light passing close to the sun which was predicted by relativity theory.
- Eddington lectured on relativity at Cambridge, giving a beautiful mathematical treatment of the topic.
- He used these lectures as a basis for his book Mathematical Theory of Relativity which was published in 1923.
- In addition to his work in relativity theory Eddington also did important work on the internal structure of stars.
- In [Eddington\'s search for a fundamental theory : a key to the universe (Cambridge, 1994).','Reference ',9)">9] Kilmister delves deeply into the ideas which led Eddington to the theories he put forward in Fundamental Theory in attempting to unite quantum mechanics and general relativity.
- It was Dirac's 1928 paper on the wave equation of the electron which had first set Eddington on the path of seeking ways to unify quantum mechanics and general relativity.

- Chazy biography
- Having done brilliant work on differential equations, Chazy's interests now turned towards the theory of relativity.
- Albert Einstein's general theory of relativity was, at this time, very new only having been published near the end of 1915.
- An important paper on relativity he published in 1924 is Sur le champ de gravitation de deux masses fixes dans la theorie de la relativite Ⓣ.
- He published the two-volume treatise The Theory of Relativity and Celestial Mechanics (1928, 1930).
- The purpose of this book, which is the development of a course taught at the Faculty of Sciences of Paris in 1927, is to expose as clearly as possible the theory of relativity in dealing with celestial mechanics, taking as a starting point the knowledge of a student who has attended a few lessons on differential and integral calculus, and mechanics.
- It discusses the principles of relativity, the equations of gravitation, the determination of ds2, Schwarzschild equations of motion, the n-body problem and finally cosmogonic hypotheses related to the ds2 of the universe.
- (3) The law of gravitation of the theory of relativity and the classical theory of perturbations;
.
- (7) Birth of the Theory of Relativity.
- While penetrating in an original and profound way the field of research opened by the relativity revolution, Chazy nevertheless remained a classically trained mathematician.
- Fock biography
- Fock had strong views on general relativity which he interpreted somewhat differently from Einstein.
- First, it is a text-book for the use of graduate students in theoretical physics, giving a complete exposition of the theories of special and general relativity.
- He objects to the use of the name "general relativity" for Einstein's theory of gravitation.
- He defines "relativity" to mean an invariance in the description of nature as viewed from different physical observation-points (not coordinate-systems).
- In this sense the gravitation theory contains less relativity than what is usually called "special relativity", and not more.
- So he vehemently insists that we call "special relativity" "relativity", and "general relativity" "gravitation theory." ..
- Lichnerowicz biography
- Chapter I (Axiomatique de la theorie de la gravitation) [gives] relevant results on the initial value problem associated with the field equations of general relativity; most important for the sequel are those which deal with the continuation of an "interior field," in a region containing matter, across a boundary into an "exterior field" in regions free of matter.
- He had continued to work on relativity theory during the war and he spoke in [22] about a particular problem from that time:-
.
- With the German occupation, very few scientific papers were available; I realized that if one wanted relativity to work well, there was a fundamental question which arose.
- The first course he gave there in the academic year 1952-53 was on the general theory of relativity.
- that general relativity, now nearly forty years old, has passed from theoretical into mathematical physics and should be treated with mathematical rigour like the theory of potential.
- In this spirit he presents relativity axiomatically, with much more attention to mathematical precision than has been customary and much less attention to its physical aspects.
- Relativite generale et theories unitaires Ⓣ which gives a rigorous mathematical treatment of more advanced topics in general relativity.
- We have already said a little about Lichnerowicz's work on Einstein's theory of general relativity.
- The papers are divided into three sections: relativity theory, differential geometry, and infinite-dimensional Lie algebras.
- Hawking biography
- From Oxford, Hawking moved to Cambridge to take up research in general relativity and cosmology, a difficult area for someone with only a little mathematical background.
- Between 1965 and 1970 Hawking worked on singularities in the theory of general relativity devising new mathematical techniques to study this area of cosmology.
- Using quantum theory and general relativity he was able to show that black holes can emit radiation.
- His success with proving this made him work from that time on combining the theory of general relativity with quantum theory.
- These mini black holes have large gravitational attraction governed by general relativity, while the laws of quantum mechanics would apply to objects that small.
- This book, which he edited, contains reprints of nearly complete editions of: Copernicus, On the revolution of the heavenly spheres (1543); Galileo, Dialogues concerning two new sciences (1638); Kepler, Harmony of the world (Book Five) (1618); Newton, Principia (1687); and seven papers on relativity by Einstein.
- Although his work on black hole thermodynamics is perhaps the most well known, Hawking has also made major contributions to the study of singularity theorems in general relativity, black hole uniqueness, quantum fields in curved spacetimes, Euclidean quantum gravity, the wave function of the universe and many other areas as well.
- In the same year Black holes and the information paradox was published, being the transcript of the famous talk Hawking gave at the 17th International Conference on General Relativity and Gravitation in Dublin in 2004.
- Reichenbach biography
- He was sent back to Berlin where by 1917 he was one of only five people who attended Einstein's first course on relativity.
- There he taught a wide variety of topics showing both the breadth of his interests and his background: relativity, philosophy of science, history of philosophy, surveying, and radio techniques.
- In the year he took up this position he published his first major text on relativity Relativitatstheorie und Erkenntnis apriori Ⓣ which attacked Kant's synthetic a priori theory of space and time, and of physics.
- This work again examined the philosophical meaning of the theory of relativity.
- Penrose biography
- One was a course by Hermann Bondi on general relativity which was fascinating ..
- The first was The apparent shape of a relativistically moving sphere while in 1960 he published A spinor approach to general relativity.
- Basically under these conditions space-time cannot be continued and classical general relativity breaks down.
- Penrose looked for a unified theory combining relativity and quantum theory since quantum effects become dominant at the singularity.
- One of Penrose's major breakthroughs was his introduction of twistor theory in an attempt to unite relativity and quantum theory.
- His deep work on General Relativity has been a major factor in our understanding of black holes.
- Sir Roger, Emeritus Rouse Ball Professor of Mathematics at the University of Oxford, has made outstanding contributions to general relativity theory and cosmology, most notably for his work on black holes and the Big Bang.
- McCrea biography
- His first research topic involved applying advanced mathematical methods to the study of quantum theory and relativity.
- In 1935 McCrea published Relativity Physics, a little book of less than 100 pages.
- provide an accessible account of the deduction of results of relativity theory which find common application in physics.
- The book studies results all taken from the theory of special relativity which are described in terms of three-dimensional vector notation.
- We have mentioned his text on relativity, but he also published many papers on the topic.
- In particular he wrote on the 'twin paradox' of relativity which states that the space-travelling member of a pair of twins would age less than the twin who remained on the earth.
- was one of the few people to take seriously the steady-state theory developed by Hermann Bondi, Thomas Gold and Fred Hoyle, and he showed how to treat the theory within the framework of general relativity.
- Sitter biography
- De Sitter corresponded with Paul Ehrenfest in 1916, and he proposed that a four-dimensional space-time would fit in with cosmological models based on general relativity.
- He published a series of papers (1916-17) on the astronomical consequences of Einstein's general theory of relativity.
- De Sitter, unlike Einstein, maintained that relativity actually implied that the universe was expanding, theoretical results which were later verified observationally and only then accepted by Einstein.
- This is a particularly simple solution of the field equations of general relativity for an expanding universe.
- Although de Sitter is best known for this work on relativity, he made many other contributions of great significance.
- The privilege accorded me involves a task of unusual difficulty, for the major part of de Sitter's work is in intricate, speculative, and mathematical fields dealing with the perturbations of the motions of bodies of the solar system according to classical celestial mechanics, and with the theory of relativity from a purely speculative point of view as well as in relation to perturbations observed, but not explained, and relativistic theoretical perturbations not perceived or as yet perceivable by observation.
- for his theoretical investigations on the orbits of the satellites of Jupiter, and for his contribution to the Theory of Relativity.
- Abraham Max biography
- During this time Abraham and Einstein disagreed strongly about the theory of relativity in a correspondence discussed in [Einstein and the history of general relativity (Boston, MA, 1989), 160-174.','Reference ',3)">3] and [Italian mathematics between the two world wars (Bologna, 1987), 143-159.','Reference ',4)">4].
- Einstein also argued about relativity in a correspondence with Levi-Civita and Abraham played a role in this argument too, see for example [Italian mathematics between the two world wars (Bologna, 1987), 143-159.','Reference ',4)">4].
- Abraham was opposed to relativity all his life.
- At first he objected both to the postulates on which relativity was based and also to the fact that he felt that the experimental evidence did not support the theory.
- By 1912 Abraham, who despite his objections was one of those who best understood relativity theory, was prepared to accept that the theory was logically sound.
- He hoped that further astronomical data would support the aether theory and show that relativity was not in fact a good description of the real world.
- Freundlich biography
- At this time Einstein was working on the general theory of relativity and, although he did not have the details of the theory worked out, he was beginning to understand some of its consequences.
- Freundlich worked with Einstein in 1911 attempting to make the measurements of Mercury's orbit required to confirm the general theory of relativity.
- Freundlich was interested in measuring the deflection in a light ray passing close to the sun since again Einstein's incomplete theory of relativity suggested that this test could be used to check the validity of the theory and show that Newton's theory was incorrect.
- He made other tests of general relativity based on gravitational redshift but these were inconclusive.
- He wrote his first book in 1916 following Einstein's publication of the general theory of relativity.
- Freundlich's book Grundlagen der Einsteinschen Gravitationstheorie Ⓣ discussed the ways that the general theory of relativity could be tested by astronomical observations.

- Choquet-Bruhat biography
- She dedicated the book General Relativity and the Einstein Equations (2009) she wrote many years later to:-
.
- Her research has created new mathematical methods that have provided a solid foundation for the study of several physical theories: the theory of general relativity, relativistic hydrodynamics, non-Abelian gauge theory, the theory of supergravity, etc.
- She introduced some new formulations of Einstein's theory of gravitation which has led to spectacular recent progress in numerical relativity, including the calculation of gravitational waves emitted during the collapse and merger of two black holes.
- Global Solutions of the Problem of Constraints on a Closed Manifold, published in 1973, shows that the existence of global solutions of the constraint equations of general relativity on a closed manifold depend on subtle properties of the manifold.
- Her latest book, General relativity and the Einstein equations was published in 2009.
- This massive book covers in detail the areas of classical mathematical relativity theory to which the author has made major contributions during her long and active research career.
- But the inclusion of some introductory chapters on Lorentzian manifolds, special relativity and kinetic theory makes it an up-to-date reference work or even a textbook for an advanced graduate course.
- Grossmann biography
- He was struggling to extend his special theory of relativity to include gravitation and immediately began collaborating with his old friend Grossmann.
- It was Grossmann who pointed out to him the relevance to general relativity of the tensor calculus which had been proposed by Elwin Bruno Christoffel in 1864, and developed by Gregorio Ricci-Curbastro and Tullio Levi-Civita around 1901.
- Compared with this problem, the original theory of relativity is child's play.
- The collaboration between Grossmann and Einstein led to the first paper on the general theory of relativity in 1913.
- Finally we should mention the honour given to Marcel Grossmann by naming the series of conferences, the Marcel Grossmann Meetings (on Recent Developments in Theoretical and Experimental General Relativity, Gravitation, and Relativistic Field Theories).
- These conferences, begun in 1975, are international meetings held every three years, which provide opportunities for discussing recent advances in gravitation, general relativity and relativistic field theories.

- Synge biography
- The origin of the name "Synge" is described in the introduction to General relativity : papers in honour of J L Synge :-
.
- Professor Synge made outstanding contributions to widely varied fields: classical mechanics, geometrical mechanics and geometrical optics, gas dynamics, hydrodynamics, elasticity, electrical networks, mathematical methods, differential geometry and, above all, Einstein's theory of relativity.
- He felt just as much at home in the ordinary three dimensional Euclidean space as in the four dimensional space-time of relativity.
- Synge retired in 1972 and during his time at the Dublin Institute for Advanced Studies about 12% of all workers in relativity theory studied there.
- Synge's classic, written in 1956, had a large influence [General relativity : papers in honour of J L Synge (Oxford, 1972), 257-265.','Reference ',1)">1]:-
.
- It is a remarkable fact that hardly a single space-time diagram is to be found in the standard texts on relativity before Synge's own presentation in 1956.
- Here was a royal road to relativity which did not involve precarious juggling with factors of √(1 - v2/c2).
- Burali-Forti biography
- However this collaboration ended when they differed in their views on relativity.
- Burali-Forti never understood the theory of relativity and, in 1924, Burali-Forti, in collaboration with Tommaso Boggio (1877-1963), published Espaces Courbes Critique de la Relativite Ⓣ.
- to consider Relativity under its mathematical aspect, wishing to point out how arbitrary and irrational are its foundations.
- [They state in the Preface] We wish to shake Relativity in all its apparent foundations, and we have reason for hoping that we have succeeded in doing it.
- Philosophy may be able to justify the space-time of Relativity, but mathematics, experimental science, and common sense can justify it NOT AT ALL.
- Marcolongo writes in [Bollettino dell\'Unione matematica italiana 10 (1931), 182-185.','Reference ',25)">25] that their disagreement on the theory of relativity was:-
.
- Weyl biography
- In his first academic year in this new post he was a colleague of Einstein who was at this time working out the details of the theory of general relativity.
- In 1917 Weyl gave another course presenting an innovative approach to relativity through differential geometry.
- He attempted to incorporate electromagnetism into the geometric formalism of general relativity.
- More recently attempts to incorporate electromagnetism into general relativity have been made by Wheeler.
- [In the fourth lecture he] shows how the special theory of relativity is essentially the study of the inherent symmetry of the four-dimensional space-time continuum, where the symmetry operations are the Lorentz transformations; and how the symmetry operations of an atom, according to quantum mechanics, include the permutations of its peripheral electrons.

- Infeld biography
- Feeling the need for wider academic contacts, he spent the year 1920 - 21 in Berlin, where he met Einstein and produced his first paper entitled "Light waves in the theory of relativity."
.
- Other papers he published around this time include (with P R Wallace, one of his doctoral students) The equations of motion in electrodynamics (1940), On the Theory of Brownian Motion (1940), On a new treatment of some eigenvalue problems (1941), A generalization of the factorization method for solving eigenvalue problems (1942), and Clocks, rigid rods and relativity theory (1943).
- The years 1950 - 68 were full of scientific activity as evidenced by the publication of more than forty papers and the book with J Plebanski 'Motion and relativity' in 1960.
- The important book Motion and relativity referred to in this quote is an important monograph.
- In it are collected "final results" of the study, begun by Infeld with Einstein and Hoffmann in Princeton in 1938, and carried on by him with his students in Warsaw during the last decade, of the problem of motion in the general relativity theory of gravitation.
- It will have permanent value, in any serious library of the subject, as a definitive, detailed account of this part of general relativity theory.
- Schouten biography
- Schouten was, as were so many mathematicians at that time, deeply interested in the theory of relativity.
- I was never so much interested in quantum mechanics as in the theory of relativity, because the Delft is vectors and tensor, and so those things had become very familiar.
- Of course, working on tensor analysis put Schouten in the exciting area of developments associated with the theory of relativity.
- He produced 180 papers and 6 books on tensor analysis, applying tensor analysis to Lie groups, general relativity, unified field theory, and differential equations.
- He also acknowledged the ideas that came about through discussions with others, for example writing in his paper Uber die Einordnung der Affingeometrie in die Theorie der hoheren Ubertragungen Ⓣ (1923) (see for example [On the History of Unified Field Theories (Living Reviews Relativity, 2004).','Reference ',2)">2]):-
.
- This text contains an excellent treatment of tensor analysis and applications to linear elasticity theory, dynamics, relativity, and quantum mechanics.
- Pauli biography
- He was certainly not a typical pupil for he read Einstein's papers on relativity while he was still at the Gymnasium.
- Within two months of leaving school he had submitted his first paper on the theory of relativity.
- While still an undergraduate at Munich he wrote two further articles on the theory of relativity.
- Sommerfeld asked Pauli to write a review article on relativity for the Encyclopadie der mathematischen Wissenschaften when he had only been two years at university, a mark of the high regard in which he held Pauli.
- Two months after the award of his doctorate Pauli's survey of the theory of relativity appeared, by this time having grown into a work of 237 pages.
- His genius was immediately recognised by Einstein who, after reading Pauli's monograph on relativity, wrote a review [The genius of science (Oxford, 2000), 210-262.','Reference ',21)">21]:-
.
- Lorentz biography
- Lorentz transformations, which he introduced in 1904, form the basis of Einstein's special theory of relativity.

- Bondi biography
- For the extrapolative theories, such as the theory of relativity, this "principle" is merely an aid to the formulation of a problem which is to be attacked within the framework of the extrapolated physical laws; for the deductive theories, such as Milne's kinematical relativity, it is an a priori requirement, a sort of categorical imperative, to which physical experience must conform.
- It would certainly be a mistake to think that this represents the most important part of Bondi's scientific work, however, for he was a leading expert on many topics in applied mathematics, in particular in relativity theory.
- Also with co-authors, he wrote a series of papers Gravitational waves in general relativity.
- In the same year he wrote the survey Relativity and cosmology and then published The contraction of gravitating sphere two years later which a referee described as an:-
.
- Also in 1964 he published Massive spheres in general relativity which he describes as follows:-
.
- Milne biography
- He developed a new form of relativity called kinematic relativity, an alternative to Einstein's general theory of relativity, which also met with considerable opposition.
- Milne's books include Thermodynamics of the Stars (1930) which contains material relating to his Smith's Prize essay discussed above, Relativity, Gravitation and World-Structure (1935), and Kinematic Relativity (1948).
- for his researches on the atmosphere of the Earth and the sun, on the internal constitution of the stars, and on the theory of relativity.
- Vagner biography
- He was particularly attracted by the theory of relativity and he now asked Igor Tamm, a professor in Moscow, if he would supervise his doctoral studies in that topic.
- Although Tamm was very interested in the theory of relativity, he was not allowed to have students in this field.
- Of course, this was a political decision by the Soviet government who had decided that relativity was not a proper science.
- Tamm had to supervise students on the physics of metals but after having discussions with Vagner he clearly saw how the young student had his heart set on studying relativity.
- The very spirit of modern geometry is close to that of relativity.
- Vagner started his research activity at the time when differential geometry was rapidly developing and providing a part of mathematical apparatus for general relativity.
- Yano biography
- Everyone in Japan was saying that the theory of relativity was so difficult that only twelve people in the world could understand it.
- I do not know how difficult the theory of relativity is to understand, but it was not created by God, it was created by a human being called Albert Einstein.
- So Kentaro! I am sure that if you study hard you may someday understand what the theory of relativity is.
- This stuck with Kentaro so when he was in secondary school and discovered that his physics textbook had an appendix on the theory of relativity, he tried to read it.
- Not finding it too difficult he spoke to his physics teacher who explained to him that what he had read was the special theory of relativity.
- To understand the general theory of relativity one had to study differential geometry.
- Poincare biography
- He made contributions to numerous branches of mathematics, celestial mechanics, fluid mechanics, the special theory of relativity and the philosophy of science.
- In applied mathematics he studied optics, electricity, telegraphy, capillarity, elasticity, thermodynamics, potential theory, quantum theory, theory of relativity and cosmology.
- He is acknowledged as a co-discoverer, with Albert Einstein and Hendrik Lorentz, of the special theory of relativity.

- Durell biography
- Among the books he wrote around this time were: Readable relativity (1926), A Concise Geometry (1928), Matriculation Algebra (1929), Arithmetic (1929), Advanced Trigonometry (1930), A shorter geometry (1931), The Teaching of Elementary Algebra (1931), Elementary Calculus (1934), A School Mechanics (1935), and General Arithmetic (1936).
- First let us look more closely at Readable Relativity.
- It is worth noting that the first text in English on relativity was by Eddington in 1923 so Durell's text came very early.
- Precise, brief, and practical, this text is the work of a highly respected teacher with years of classroom experience, who sketches the mathematical background essential to a clear understanding of the fundamentals of relativity theory.
- The best layman's introduction to relativity that has ever been written by anybody.
- Lemaitre biography
- Einstein was at the conference and he spoke to Lemaitre in Brussels telling him that the ideas in his 1927 paper had been presented by Friedmann in 1922, but he also said that although he thought Lemaitre's solutions of the equations of general relativity were mathematically correct, they presented a solution which was not feasible physically.
- In 1949 he returned to his study of an expanding universe in Cosmological application of relativity.
- The paper opens with a rapid expository review of the general relativity theory of gravitation, including discussion of kinematics, conservation laws, spherical symmetry, and the solutions of Schwarzschild and de Sitter in terms of comoving coordinates.
- We end this biography by quoting from a review by R N Tiwari of [Studies in the history of general relativity, Luminy, 1988, Einstein Stud.
- He joined the army and, to quote from the author's statement, "after 53 months of war ordeals and military camps, he lost interest in a professional career and decided to become a priest"; this ultimately resulted in a change from engineering to the mathematical sciences, particularly to general relativity, which marked a very notable turning point in Lemaitre's life.
- Minkowski biography
- Einstein was a student in several of the courses he gave and the two would later become interested in similar problems in relativity theory.
- Minkowski developed a new view of space and time and laid the mathematical foundation of the theory of relativity.
- This space-time continuum provided a framework for all later mathematical work in relativity.
- These ideas were used by Einstein in developing the general theory of relativity.

- Segal biography
- CC assumes special relativity (SR) as a local theory inasmuch as this can be identified with M'.

- 20th century time
- Although Poincare was thinking deeply about relativity before Einstein, it was the latter who made the final breakthrough.
- The impact of the special theory of relativity on the understanding of time was enormous.
- There were other remarkable effects on time with special relativity.
- Before we move on from special relativity, we must consider one aspect which seems particularly difficult in Minkowski's 4-dimensional space-time, and indeed in any version of relativity.
- In fact all relativity seems to have done is to make us realise that time is a much more difficult concept than Newton's absolute time.
- General relativity incorporated gravitation into the space-time theory.
- Not only was time affected by velocity, as special relativity showed, but time was also affected by a massive body.
- If we cannot measure the height of the box to arbitrary precision, we cannot measure the height of the clock inside the box with arbitrary precision, so we do not know the rate of the clock with arbitrary precision (by Einstein's own general relativity results).
- In the "clock in the box" thought experiment we have seen how relativity and quantum theory begin to interact.
- Milne developed a complex theory of cosmology, attempting to unify relativity and quantum theory, that included a non-constant value for G, which we know as the gravitational constant.
- There are ways that quantum theory time appears to contradict relativity time, and this is worrying.
- This violates the basic principle of relativity that no information can be transmitted faster than the speed of light.
- Newton's bucket
- After Einstein introduced the special theory of relativity in June 1905 the concept of absolute space was no longer tenable.
- But how can rotation mean anything once the notion of absolute space has been cast aside? Well the special theory of relativity still has absolutes.
- Absolute space-time is a feature of special relativity which, contrary to popular belief, does not claim that everything is relative.
- In special relativity observers moving at constant velocities relative to each other would not agree on the velocity of a bucket moving through space, nor would they agree about the time that has elapsed in the bucket experiment, but they would all agree on whether the bucket was accelerating or not.
- After this Einstein began working on the theory of general relativity which incorporated acceleration and gravity.
- He did so in a letter which he wrote to Mach in 1913 in which he told Mach that his view of Newton's bucket was correct and agreed with general relativity.
- Einstein even included "Mach's principle" into general relativity.
- General relativity does not say that Newton's two rock thought experiment in an empty universe agrees with Mach.
- Hence general relativity reduces to special relativity and now all observers agree when the rock system is spinning (i.e.
- In 1918 Joseph Lense and Hans Thirring obtained approximate solutions of the equations of general relativity for rotating bodies.
- Modern light
- Light through the ages: Relativity and quantum era
.
- Einstein published the special theory of relativity in the following year which is based on the remarkable suggestion that the speed of light remains constant for all observers independent of their relative velocities.
- In 1915 Einstein published the general theory of relativity which predicted the bending of rays of light passing through a gravitational field.
- Although his observations were hampered by the weather he was able to get one good value which confirmed the bending predicted by general relativity.
- There was a time when the newspapers said that only twelve people understood the theory of relativity.
- But after people read the paper a lot of people understand the theory of relativity in some way or other, certainly more than twelve.

.
- He chose as his topic Ether and the Theory of Relativity.
- Ether and the Theory of Relativity
.
- This theory - also called the theory of the stationary luminiferous ether - moreover found a strong support in an experiment which is also of fundamental importance in the special theory of relativity, the experiment of Fizeau, from which one was obliged to infer that the luminiferous ether does not take part in the movements of bodies.
- It may be added that the whole change in the conception of the ether which the special theory of relativity brought about, consisted in taking away from the ether its last mechanical quality, namely, its immobility.
- The space-time theory and the kinematics of the special theory of relativity were modelled on the Maxwell-Lorentz theory of the electromagnetic field.
- This theory therefore satisfies the conditions of the special theory of relativity, but when viewed from the latter it acquires a novel aspect.
- But by the special theory of relativity the same equations without any change of meaning also hold in relation to any new system of co-ordinates K' which is moving in uniform translation relatively to K.
- This conception suggests itself the more readily as, according to Lorentz's theory, electromagnetic radiation, like ponderable matter, brings impulse and energy with it, and as, according to the special theory of relativity, both matter and radiation are but special forms of distributed energy, ponderable mass losing its isolation and appearing as a special form of energy.
- More careful reflection teaches us however, that the special theory of relativity does not compel us to deny ether.
- We shall see later that this point of view, the conceivability of which I shall at once endeavour to make more intelligible by a somewhat halting comparison, is justified by the results of the general theory of relativity.
- The special theory of relativity forbids us to assume the ether to consist of particles observable through time, but the hypothesis of ether in itself is not in conflict with the special theory of relativity.
- Certainly, from the standpoint of the special theory of relativity, the ether hypothesis appears at first to be an empty hypothesis.
- Mach's idea finds its full development in the ether of the general theory of relativity.
- The ether of the general theory of relativity is a medium which is itself devoid of all mechanical and kinematical qualities, but helps to determine mechanical (and electromagnetic) events.
- What is fundamentally new in the ether of the general theory of relativity as opposed to the ether of Lorentz consists in this, that the state of the former is at every place determined by connections with the matter and the state of the ether in neighbouring places, which are amenable to law in the form of differential equations; whereas the state of the Lorentzian ether in the absence of electromagnetic fields is conditioned by nothing outside itself, and is everywhere the same.
- The ether of the general theory of relativity is transmuted conceptually into the ether of Lorentz if we substitute constants for the functions of space which describe the former, disregarding the causes which condition its state.
- Thus we may also say, I think, that the ether of the general theory of relativity is the outcome of the Lorentzian ether, through relativation.
- The contrast between ether and matter would fade away, and, through the general theory of relativity, the whole of physics would become a complete system of thought, like geometry, kinematics, and the theory of gravitation.
- Recapitulating, we may say that according to the general theory of relativity space is endowed with physical qualities; in this sense, therefore, there exists an ether.
- According to the general theory of relativity space without ether is unthinkable; for in such space there not only would be no propagation of light, but also no possibility of existence for standards of space and time (measuring-rods and clocks), nor therefore any space-time intervals in the physical sense.

- The tendency to this kind of definition had progressed far even in pre-relativity physics.
- Mass is defined by experiments on inertial properties, no longer as "quantity of matter." But for some terms the older kind of definition (or lack of definition) has been obstinately adhered to; and for these the relativity theory must find new definitions.
- We decide that time is relative to an observer; that is to say, we admit that an observer on another star, who carries out all the rest of the operations and calculations as specified in our definition, is also measuring time - not our time, but a time relative to himself The same relativity affects the great majority of elementary physical quantities (the most important exceptions are number (of discrete entities), action, and entropy); the description of the operations is insufficient to lead to a unique answer unless we arbitrarily prescribe a particular motion of the observer and his apparatus.
- In this example we have had a typical illustration of "relativity," the recognition of which has had far-reaching results revolutionising the outlook of physics.
- The principle of relativity goes still further.

.
- During the ensuing eighteen months I have pursued my intention of developing it into a more systematic and comprehensive treatise on the mathematical theory of Relativity.
- But it is eminently desirable to- have a general grasp of the revolution of thought associated with the theory of Relativity before approaching it along the narrow lines of strict mathematical deduction.

- A H Taub writes: The fundamental results of E A Milne's kinematical relativity are derived from nine axioms.
- It is argued that kinematical relativity cannot be applied to a physical theory without the addition of a further axiom which would enable one to identify a theoretical observer with a terrestrial one.
- The regraduation of clocks in spherically symmetric space-times of general relativity (1945).
- Arthur Walker writes: This paper gives a preliminary examination of the question as to whether general relativity admits clock regraduations other than trivial coordinate transformations, a question which has been suggested by recent kinematical theories of relativity.
- H P Robertson writes: The first three of the five chapters present a rapid survey of our knowledge of extra-galactic nebulae, of the tensor calculus and of the principles of the general theory of relativity.
- McVittie writes: The possibility of the existence of negative stress in the general relativity treatment of a perfect fluid is used to construct a model universe which is in a 'gravitationally steady state'.

- This is the crucial assumption on which Einstein's general theory of relativity is based.
- The theory of relativity teaches us that the Earth, placed at a certain distance from the Sun and given an initial speed, will be guided, due to the Sun's gravitation - as if an invisible surface connected the two subsequent orbital positions - along the shortest path which connects these two positions.
- In the theory of relativity no such force is envisaged.
- And, what is of even greater importance, the coincidence between the Kepler orbit and the orbit of a planet moving according to the theory of relativity in a quasi non-Euclidean space, is not complete.
- This difference corresponds accurately, in value and character, to the deviation in the motion of Mercury, which had been discovered long before the theory of relativity was conceived and which I have already mentioned.
- For a full agreement between the predictions of the theory of relativity and astronomical observations has not yet been achieved in all observable effects.
- While the motion of a body, like Mercury, seems to follow the laws set up by the theory of relativity, light, i.e.
- The theory of relativity teaches that between matter and energy no fundamental difference exists in so far as the one may be converted into the other.
- The theory of relativity claims therefore that the same laws of motion hold good for moving energy as for moving matter.
- But the observations yield a considerably larger value for the deflection than is predicted by the theory of relativity.
- Although followers of Einstein's theory of relativity are reluctant, to say the least, even to consider such a possibility, it may not be overlooked that also in other respects a deep gap is dividing the two branches of physics the one approaching the phenomena from a macroscopic point of view; this is the theory of relativity; the other, the quantum theory, based on fundamentally different conceptions, which takes account of the atomic structure of matter and the quantum structure of energy.
- Einstein: 'Geometry and Experience
- I attach special importance to the view of geometry which I have just set forth, because without it I should have been unable to formulate the theory of relativity.
- The idea of the measuring-rod and the idea of the clock co-ordinated with it in the theory of relativity do not find their exact correspondence in the real world.
- Not only the practical geometry of Euclid, but also its nearest generalisation, the practical geometry of Riemann, and therewith the general theory of relativity, rest upon this assumption.
- Thence it follows that the above assumption for tracts must also hold good for intervals of clock-time in the theory of relativity.
- Let us call to mind what the general theory of relativity teaches in this respect.
- The general theory of relativity teaches that the inertia of a given body is greater as there are more ponderable masses in proximity to it; thus it seems very natural to reduce the total effect of inertia of a body to action and reaction between it and the other bodies in the universe, as indeed, ever since Newton's time, gravity has been completely reduced to action and reaction between bodies.
- From the equations of the general theory of relativity it can be deduced that this total reduction of inertia to reciprocal action between masses - as required by E Mach, for example - is possible only if the universe is spatially finite.
- For if we inquire into the deviations shown by the consequences of the general theory of relativity which are accessible to experience, when these are compared with the consequences of the Newtonian theory, we first of all find a deviation which shows itself in close proximity to gravitating mass, and has been confirmed in the case of the planet Mercury.
- From the latest results of the theory of relativity it is probable that our three-dimensional space is also approximately spherical, that is, that the laws of disposition of rigid bodies in it are not given by Euclidean geometry, but approximately by spherical geometry, if only we consider parts of space which are sufficiently great.
- Tullio Levi-Civita
- Levi-Civita.html
- There are few modern branches of mathematical physics to which he did not at one time or another contribute - classical mechanics, hydromechanics, thermodynamics, elasticity, the strength of materials, astronomy, electromagnetism, optics, relativity and quantum mechanics - yet some of his greatest work was in pure mathematics.
- Their work gained relatively little attention until, fifteen years later, it was used by Einstein in the formulation of the general theory of relativity.
- Originally it was a technique rather than a separate branch of mathematics, providing as it did a way of writing theorems of differential geometry and the calculus in a form at once concise and general, and it was not until after the development of relativity, followed shortly afterwards by Levi-Civita's definition of parallelism in Riemannian geometry, that it assumed the full place it now holds as one of the main branches of modern mathematics.
- He made numerous other contributions to relativity, and in 1933 interested himself in the problem of reconciling Dirac's equations in quantum mechanics with the relativistic principle of covariance.
- Regarding the last, it is interesting to note that, in his own words, "Dirac's equations must, in my opinion, be abandoned, without, it is understood, giving up the main progress realised by them in the domain of restricted relativity" - this because their transformation-laws seemed to him to require the introduction into space-time of a lattice (a system of four mutually perpendicular congruences of lines) which, having no intrinsic physical significance, should, but in fact did not, disappear from the equations in their final relativistic form.
- This discovery by Levi-Civita, together with the contemporary development of general relativity and the search for a unified theory of gravitation and electromagnetism by Weyl, Eddington, Einstein and others, quickly led to generalisations of Riemannian geometry.
- By his early work with Ricci on tensor analysis and by his later discovery of infinitesimal parallelism, Levi-Civita laid the foundations both for relativity and for the establishment of differential geometry as one of the great branches of modern mathematics.

- Eddington on the Expanding Universe
- He found that, on one of two alternative hypotheses arising out of Einstein's relativity theory, the light of very remote objects should be displaced to the red as though they were moving away from us; and he suggested the observed motions of the spiral nebulae (by far the most remote objects known) as a discriminating test.
- We see, then, that according to observation the system of the spiral nebulae is expanding, and that relativity theory had foreseen just such an expansion (except that as an alternative it would have been content with an equally regular contraction).
- That is one of the results of Einstein's theory which has become almost a commonplace of physics; but it was a rather complicated kind of relativity that Einstein considered - relativity to the motion of our frame of reference.
- I am going to refer to another much more elementary relativity of length, viz.
- We can feel little doubt therefore that the observed motions of the nebulae are genuine and represent the expansion effect predicted by relativity.
- EMS 1913 Colloquium
- Professor A W Conway, of the National University of Ireland, is taking for his subject "The Theory of Relativity and the New Physical Ideas of Space and Time;" Dr Sommerville, of St Andrews University, lectures on "Non-Euclidean Geometry and the Foundations of Geometry;" and Professor Whittaker, Edinburgh University, gives a course of five lectures and demonstrations on "Practical Harmonic Analysis and Periodogram Analysis." By the courtesy of the University Court, several rooms have been set aside as reception and writing rooms, and these have been furnished for the comfort and convenience of members of the colloquium.
- The theory of relativity after Einstein started by asserting the impossibility of observing the absolute velocity of the observer.
- Professor A W Conway delivered his second lecture on "Relativity." In the course of the lecture the relations between the coordinates and time in the two systems of reference were deduced.
- Professor A W Conway delivered the third lecture on Relativity.
- The fourth lecture on "Relativity" was delivered by Professor Conway.
- Professor Conway delivered his concluding lecture on "Relativity." The ideas of Minkowsky were explained.
- Born Inaugural
- Einstein's theory of relativity of 1905 can be considered as being at once the culmination of classical ideas and the starting-point of the new ones.
- The most important consequences of this conception were deduced by Einstein, who laid the foundations of the quantum theory of light in 1905, the year in which he published his relativity theory, and by Niels Bohr in 1913, when he applied the idea of the quantum to the structure of atoms.
- Relativity gave the first example in which the intrusion of the observer into the description of facts is not so simple, and leads to a new conception to conserve the idea of an objective world Einstein has acknowledged that his studies on this problem were deeply influenced by the ideas of Ernst Mach, a Viennese physicist who developed more and more into a philosopher.
- When I wrote a popular book on relativity in 1920 I was so impressed by this wonderful construction that I represented this method of objectivation as the central achievement of science.
- In the case of relativity this evidence was strong indeed, but consisted to a large extent of negative statements, such as that mentioned above regarding the absence of an ether-wind.
- We thus meet a situation similar to that in relativity, but much more complicated.
- Eddington on the Expanding Universe
- Whittaker EMS Obituary.html
- Consequently, lectures were given by D M Y Somerville on Non-euclidean geometry and the foundations of geometry and by A W Conway [Arthur Conway] on The theory of relativity and the new physical ideas of space and time.
- Later on, he became intensely interested in the Theory of Relativity and wrote a number of papers on some of its mathematical aspects; these are discussed by J L Synge in a paper on pages 39-55 of this Whittaker Memorial Number.
- His interest in Relativity manifested itself also at the undergraduate level, for the Honours course entitled Higher Algebra and Geometry contained neither Algebra nor Geometry in the ordinary sense of these terms but comprised Tensor Calculus with Riemannian Geometry and its generalisations.
- The second volume, which appeared in 1953, contains an account of the developments which took place between 1900 and 1926 and is mainly concerned with Relativity and the Quantum Theory.
- One of the few subjects on which I have never heard him discourse is Geometry in the Bakerian sense; Geometry for him meant Riemannian geometry which is used in Relativity and contributes to our understanding of the material universe.
- He was also President of Section A of the British Association in 1927 and his presidential address on The Outstanding problems of relativity dealt with a number of matters which are still not settled.
- EMS 1934 Colloquium
- World-Structure by the Kinetic Methods of the Special Theory of Relativity.
- The principal course of lectures, delivered by Professor E A Milne (Oxford), dealt with the problem of world-structure by the kinematical methods of special relativity.
- This theory, developed by Prof Milne himself, seeks to account for the structure of the system of the spiral nebulae and the recession phenomenon without using general relativity.
- de Sitter and others took part, it was pointed out that Prof Milne's theory had brought into prominence the fact that in general relativity also the scattering of the nebulae went on independently of gravitation.
- One, delivered by Prof W de Sitter, was a masterly exposition of the subject of the Expanding Universe from the observational point of view and from that of an expert in general relativity.
- Levi-Civita: 'Absolute Differential Calculus
- Two new chapters have been added, which are intended to exhibit the fundamental principles of Einstein's General Theory of Relativity (including, of course, as a limiting case, the so-called Special or Restricted Theory) as an application of the Absolute Calculus.
- I have already had occasion to remark in the Preface to the Italian edition that we possess various systematic and well-written expositions of Relativity by celebrated authors.
- The sacrifice is certainly regrettable, since Electromagnetism was historically related in the most intimate way to Einstein's conception, having served indeed as the support and model for Restricted Relativity.
- Furthermore, Electromagnetism, in common with every other physical phenomenon, now comes within the ambit of General Relativity.
- For this reason I have followed the method - which I have adopted sometimes in lectures or articles on special subjects of taking the classical laws as the starting point and then of trying to find inductively what modifications - negligible in ordinary circumstances - should be introduced in order to take account of Einstein's ideas; and in the first place, naturally, to take account of his Principle of Relativity, that is to say, the invariant behaviour of these laws under all transformations of space and time, an auxiliary four-dimensional ds2being duly employed.
- Landau and Lifshitz reviews
- The presentation is based throughout on two general principles, namely on Galileo's relativity principle and on Hamilton's principle of least action.
- The present edition has been expanded by about 50 pages, mostly by extension of the discussion of the general theory of relativity.
- The authors summarize in neat and compact form those features of the classical theory of the electromagnetic field and the general theory of relativity which theoretical physicists are expected to know.
- The level of sophistication is determined by the fact that the book starts with a discussion of the special theory of relativity, while the derivations of the equations of motion and the field equations are based on variational principles, most of the derivations being purely formal.

- Von Neumann: 'The Mathematician' Part 2
- As I have pointed out before, Euclid's system of geometry was the prototype of the axiomatic presentation of classical mechanics, and similar treatments dominate phenomenological thermodynamics as well as certain phases of Maxwell's system of electrodynamics and also of special relativity.
- Michelson's experiment leading to special relativity, the difficulties of certain ionization potentials and of certain spectroscopic structures leading to quantum mechanics exemplify the first case; the conflict between special relativity and Newtonian gravitational theory leading to general relativity exemplifies the second, rarer, case.
- Landau and Lifshitz Prefaces
- From the very beginning it is based on the most general principles: Galileo's principle of relativity, and Hamilton's principle of least action.
- A complete, logically connected theory of the electromagnetic field includes the special theory of relativity, so the latter has been taken as the basis of the presentation.
- the general theory of relativity.
- Tietze: 'Famous Problems of Mathematics
- If a work by Albert Einstein can now be quoted without further ado, at that time the book's chances of appearing were endangered by mere mention in it of the theory of relativity, which had the effect of a red flag on many in those days when, blinded by the universal propaganda, some scientists really believed that this theory was pure humbug and when, worse still, one of our greatest theoretical physicists was replaced by a man, foisted upon us from on high, who tossed Planck's quantum theory into the same kettle of damnation with the theory of relativity, so that our theoretical physicists had great difficulty in interceding on behalf of continued use of the theory of relativity in research and in teaching.
- Max Planck: 'Quantum Theory
- The undetermined additive constant in the expression for energy was fixed later by the relativity theorem of the relation between energy and inertia.
- In the face of these numerous verifications (which could be considered as very strong proofs in view of the great accuracy of spectroscopic measurements), those who had looked on the problem as a game of chance were finally compelled to throw away all doubt when A Sommerfeld showed that - by extending the laws of distribution of quanta to systems with several degrees of freedom (and bearing in mind the variability of mass according to the theory of relativity) - an elegant formula follows which must, so far as can be determined by the most delicate measurements now possible (those of F Paschen), solve the riddle of the structure of hydrogen and helium spectra.
- It must seem a curious coincidence that at the time when the idea of general relativity is making headway and leading to unexpected results, Nature has revealed, at a point where it could be least foreseen, an absolute invariable unit, by means of which the magnitude of the action in a time space element can be represented by a definite number, devoid of ambiguity, thus eliminating the hitherto relative character.
- George Temple's Inaugural Lecture II
- The romantic themes of relativity, plasticity, and gas dynamics have captured the imagination of the young mathematical physicist.
- In physics, the special theory of relativity is justly famous for its power of co-ordinating a vast array of puzzling phenomena, but many a physicist would confess to a feeling of personal loss now that relativity seems to have eliminated the aether and to have offered in its place only the principle of the inaccessibility of the velocity of light.
- Max Planck: 'The Nature of Light
- That which has harmed it most is the result, deduced from Einstein's theory of relativity, that there can be no objective substantial ether, i.e.
- For, if that were not so, then when we consider two observers moving relative to one another in space, one at most could correctly assert that he was at rest relative to the ether, whereas, by the theory of relativity, each of the two could do so equally correctly.
- The energy contained in every gram of a substance, according to the theory of relativity, amounts to over 20 billion calories, quite independently of its temperature - more than sufficient to liberate countless electrons.

- Arthur Eddington's 1927 Gifford Lectures
- The theory of relativity and the quantum theory have led to strange new conceptions of the physical world; the progress of the principles of thermodynamics has wrought more gradual but no less profound change.
- It would not serve my purpose to give an easy introduction to the rudiments of the relativity and quantum theories; it was essential to reach the later and more recondite developments in which the conceptions of greatest philosophical significance are to be found.
- For that reason I would like to recall that the idealistic tinge in my conception of the physical world arose out of mathematical researches on the relativity theory.
- James Jeans: 'Physics and Philosophy' II
- (3) Einstein's relativity theory of gravitation, which is purely geometrical in form.
- The first is provided by the theory of relativity.
- But the, theory of relativity shows that if motions are attributed to forces, these forces will be differently estimated, as regards both quantity and quality, by observers who happen to be moving at different speeds, and furthermore that all their estimates have an equal claim to be considered right.
- Élie Cartan reviews
- In the text he develops the theory from the beginning, the first volume being devoted to spinors in three-dimensional space and the second to spinors in n-dimensional space, with special reference to the four-dimensional space-time of Special Relativity.
- The second part is devoted to the theory of spinors in spaces of any number of dimensions, and particularly in the space of special relativity (Minkowski space).
- In this connection, Cartan shows how to derive the "Dirac" equation for any group, and extends the equation to general relativity.
- E P Adams
- The most striking theoretical development of the period, the theory of relativity, also attracted Adams, and he was the translator for the lectures that Einstein gave in Princeton in 1921, which appeared as The Meaning of Relativity.
- Von Neumann: 'The Mathematician
- The discovery of general relativity forced a revision of our views on the relationship of geometry in an entirely new setting and with a quite new distribution of the purely mathematical emphases, too.
- And these two seemingly conflicting attitudes are perfectly compatible in one mathematical mind; thus Hilbert made important contributions to both axiomatic geometry and to general relativity.
- Bell papers
- Non-Euclidean geometry, with all of its deep implications for metaphysics no less than for physics, began to pass into the common stock of knowledge only with the popularity of Einstein's general relativity long after it had been a commonplace t, the geometers.
- How some philosophers of science and others have the audacity to write on relativity and the quantum theory without a reading knowledge of the calculus is the wonder of the ages.
- Science at St Andrews
- Each is distinguished as a geometer; and Sommerville was led in a deep and scholarly way, particularly to the bypaths of Non-Euclidean Geometry years before the advent of relativity brought it into prominence.
- In 1938, and, as a fitting sequel to the celebrations, an astronomer was appointed - Dr Findlay Freundlich, at the recommendation of Sir Arthur Eddington who had been the first to introduce into Britain the general theory of relativity.
- Edmund Whittaker: 'Physics and Philosophy
- This is, of course, claimed only for the departments of the physical world where General Relativity does not enter.
- The question as to which class does a theory belong has, with the advent of relativity and quantum theory, ceased to have a meaning.
- Atiyah reviews
- This book is interdisciplinary and addresses concerns of theoretical physicists interested in elementary particles or general relativity and mathematicians working in analysis or geometry.
- In earlier periods geometry and physics interacted at the classical level, as in Einstein's theory of general relativity, with gravitational force being interpreted in terms of curvature.

- He speaks of integral equations and the notion of relativity as two of the more important contributions made to the science since his last edition in 1900, and promises an application of the first in the present volume.
- Undoubtedly the systematic development of integral equations and their applications, of the principle of relativity, and in all likelihood, of Lebesgue's theory of integration, will make necessary at some future time a book treating the same subjects in radically new ways.
- H Weyl: 'Theory of groups and quantum mechanics'Preface to Second Edition
- This extension already leads so far away from the fundamental purpose of the book that I felt forced to omit the formulation of the quantum laws in accordance with the general theory of relativity, as developed by V Fock and myself, in spite of its desirability for the deduction of the energy-momentum tensor.
- The insight into the significance of these constants, obtained by the theory of relativity on the one hand and quantum theory on the other, is most forcibly expressed by the fact that they do not occur in the laws of Nature in a thoroughly systematic development of these theories.

- Professor Whittaker covered this immensity, and described the stages in which the transformation took place, through relativity, the early quantum theory and its developments up to the latest speculations on heavy electrons and cosmic rays.
- Jacques Hadamard's failures
- Absolute differential calculus is closely connected with the theory of relativity; and in this connection, I must confess that, having observed that the equation of propagation of light is invariant under a set of transformations (what is now known as Lorentz's group) by which space and time are combined together, I added that "such transformations are obviously devoid of physical meaning." Now, these transformations, supposedly without any physical meaning, are the base of Einstein's theory.

- George Temple's Inaugural Lecture I
- There were the strange and puzzling experimental results of Arago, Fresnel, and Michelson; difficulty after difficulty in the theories of a universal aetherial medium for the transmission of light and electromagnetic action; and finally the sudden discovery by Einstein of the Special Theory of Relativity in the light of which all the optical phenomena form a harmonious whole.

- Studies presented to Richard von Mises' Introduction
- In drawing such a picture, the central task is to understand the relation between the direct sense observation of the experimental physicist and the conceptual system of science, which consists of expressions such as "increase of entropy" or "principle of relativity." Most physicists are inclined to say that the picture drawn and the principles devised by our inductive ability are eventually checked by actual measurement of physical quantities like length, weight, electric charge, etc., but they use the expression "measurement of a length" in a perfunctory way, forgetting that no numerical value can ever be assigned to a length by a single measurement.

- I once heard a lecture by a physicist in which he derided what he thought were the futilities of pure mathematics; but then he referred to some theorem of pure mathematics which, fifty years after its discovery, had found an application in relativity, and this seemed to him little short of miraculous.
