Another Press Release.
The following press release described the courses at the colloquium:
GREGORY TERCENTENARY.
Colloquium at St Andrews.ADVANCE OF MATHEMATICS. In connection with the James Gregory tercentenary the Edinburgh Mathematical Society are holding a Colloquium in St Andrews this week and next. Professor H W Turnbull is delivering a series of lectures on the work of James Gregory. During the last seven years of his life, said the speaker, he refused to publish any of his work, except one trifling little thing which he put in at the end of a book, entitled, The New Art of Weighing Vanity. The reason was that he was waiting for Newton to publish his works.
In his lectures Professor Turnbull has been laying bare the proof of what Gregory actually discovered. For example he had evolved a theory of the calculus that we taught in schools today, except for the notation.
The interest of his work lay in the fact that he had thought of those things before anyone else except Fermat in France and Dr Pell in Switzerland and in England. The next advance in that theory did not take place until a century later at the time of Lagrange.
PROFESSOR WHITTAKER'S COURSE. Professor E T Whittaker Is giving a course on "The Interactions between the Elementary Particles of the Universe." The first lecture dealt with the modifications which the Newtonian theory has undergone in consequence of the discovery of Relativity. The second lecture, yesterday morning was concerned with the "exchange interaction" which accounts for the binding of two atoms of hydrogen into a hydrogen molecule.
Professor M Fréchet, of the university of Paris, who recently published a book on "The Definition of Probability" in two lectures expounded the diverse definitions which have been given of the probability of an event and has compared their respective values. Dr A C Aitken, of Edinburgh, dealt with "Invariant Matrices and the Symmetric Group." Dr W O Kermack. Edinburgh, spoke on "Aspects of Mathematical Biology."
Report of George Lawson's Lecture.
One of the papers read to the Colloquium (on Saturday 9 July) was by George Lawson, president of the Edinburgh Mathematical Society. The following report of the lecture appeared in The Scotsman on Monday 11 July:
Teaching of Algebra in Schools At the St Andrews Mathematical Colloquium, which is being held in connection with the James Gregory Tercentenary at University Hall, St Andrews, Mr George Lawson, president of the Edinburgh Mathematical Society, on Saturday night submitted for debate a paper on "Neglect of Form and Law in School Algebra." He said that by the British Association papers last year, it was indicated that algebra had, during the last 30 years, developed on the lines of Sir Percy Nunn's classical exposition. That same development was indicated also in 1935 by the Mathematical Association's special pamphlet on the teaching of algebra in schools. In criticising that development, Mr Lawson referred to another development which seemed possible 30 years ago, and said it was based largely on a book quoted by Sir Percy Nunn himself  namely, that of Barnard and Child. Mr Lawson took up the position that algebra at that time took the wrong road, and he advocated a modification of the Barnard and Child position.
Report on the St Andrews Mathematical Colloquium, 1938.
A report on the Colloquium, written by I M H Etherington, appeared in The Mathematical Gazette later in 1938. The full reference is I M H Etherington, Edinburgh Mathematical Society: St Andrews Colloquium, The Mathematical Gazette 22 (252) (December 1938), 482484. We present below a version of this report:
EDINBURGH MATHEMATICAL SOCIETY:
ST ANDREWS COLLOQUIUM.This Colloquium, held at St Andrews from July 4 to 15, was in every way as successful as its quadrennial predecessors. A hundred and ten persons attended, including about twenty wives and daughters of mathematicians; including also twentyone professors of mathematics from the universities of Great Britain, Eire, France, Holland, Denmark, and the United States.
Halfway through, a professor was heard to boast that he had talked no mathematics so far, on the other hand, many members of the Colloquium found it a grand opportunity for talking fruitful shop. The arrangement of the timetable encouraged the morning coffee habit; so the café gardens of the town, and in lesser concentration the roads and walks about the place, were the scene of much deep talk on the foundations of probability, theories of the universe, and the personalities of mathematicians.
The Colloquium associated itself in various ways with the name of James Gregory, born 300 years ago, who held in succession the Chairs of Mathematics in the Universities of St Andrews and Edinburgh. The opening meeting on July 4 was held in Edinburgh in conjunction with the James Gregory Tercentenary Meeting of the Royal Society of Edinburgh. Two events of this meeting may be recorded here: the presentation to the R.S.E. of the portrait of its President, Sir D'Arcy W Thompson, painted by Mr David S Ewart, A.R.S.A. and the presentation to Professor H S Ruse of the Society's "Keith Prize" for his work on the geometry of Dirac's equations.
Next day the University of St Andrews marked Gregory's tercentenary by conferring the Honorary Degree of LL.D. on five distinguished mathematicians, members of the Colloquium being invited to the celebrations. The graduands were Professor G D Birkhoff (Harvard), Professor A W Conway (Dublin), Professor Otto Neugebauer (Copenhagen), Professor R Weitzenböck (Amsterdam), and in absentia Professor V Volterra (Rome). The ceremony took place in the University Library, where Gregory used to work; here also some MSS., instruments and other relies of Gregory were exhibited.
Professor H W Turnbull, Gregory's present successor as Regius Professor of Mathematics at St Andrews, lectured on these two occasions, and again in the course of the Colloquium, on Gregory's life and work, and especially on his many unpublished discoveries. Professor Turnbull, has made an exhaustive study of Gregory's MSS. and proved that he should rank with Barrow, Newton and Leibniz as a founder of the Calculus.
Of the four main courses of lectures, two were on subjects of pure mathematics. Professor G D Birkhoff lectured on Analytic Deformations and Autoequivalent Functions, and Dr A C Aitken on Invariant Matrices and the Symmetric Group. An analytic deformation of a function f(x) in the neighbourhood of x = infinity means replacing the independent variable by an analytic function of itself, x' = f(x), which has a simple pole at infinity. All such deformations form a group. The function x^{k} has the property of being multiplied by a function which is analytic and nonzero at infinity when any deformation of the group is applied. Other functions, such as G(x), have this property only for a smaller group of deformations; in this case
x' = x + any integer.
Such functions are autoequivalent, and Professor Birkhoff classifies them into eight types according to the defining group. The theory, which promises to unify much of modern analysis in one comprehensive sweep, is to be published by the Institut Henri Poincaré. Unification was also an achievement of Dr Aitken's course on algebra, which led through symmetric functions, finite groups, determinants and permanents, Young's standard tableaux, and Schur's invariant matrices to the foreshadowing of a master theorem which would combine them all.
On the side of applied mathematics, Professor E T Whittaker gave five lectures on "The Interactions between the Elementary Particles of the Universe". The modern picture of these particles differs immensely from the classical views of Newton and Maxwell. 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.
The fourth main course was entitled Aspects of Mathematical Biology. Dr W 0 Kermack discussed the integral equations which arise in the mathematics of population growth and of epidemiology. Dr I M H Etherington surveyed Volterra's mathematical theory of the struggle for life and its analogies in classical dynamics. It was impossible not to admire Dr Kermack's masterful exposition of his complicated subject matter, aided by lantern slides displaying his formulae but without the gift of sight.
Professor M Fréchet lectured and introduced a discussion on the various definitions of probability. He sketched the views of Laplace, de Mises, Wald and others, and described in more detail the "modernised classical definition" of Neyman and Kolmogorov. The discussion was noteworthy for Professor Whittaker's vigorous defence of the classical (Laplace's) point of view against all comers.
Mr George Lawson, the President of the Edinburgh Mathematical Society and Chairman of the Colloquium, addressed himself mainly to school teachers, who formed a not inconsiderable proportion of the membership. Mr Lawson regretted the lack of sincerity in much modern teaching, and urged the importance in teaching algebra of noticing its formal aspect algebra is the study of the forms in which numbers cooperate Professor Otto Neugebauer entertained us for half an hour on the subject of Babylonian astronomy, and on the differences between Babylonian and Egyptian science.
Finally, I must not forget to mention Professor Birkhoff's fourth lecture, which was not on autoequivalent functions but on The Mathematical Theory of Art. He claims to have found a formula for the aesthetic value of any work of art in its formal aspects, and to have devised rules by which it can be applied with demonstrable success in certain cases of special simplicity. The theory, which is little known on this side of the Atlantic, was received by a crowded audience with much interest and a certain scepticism.
Our hosts, Professor and Mrs Turnbull, entertained us and many visitors at a reception one musical evening; and many less formal moments musicaux occurred. An incomparable five minutes from Sir D'Arcy Thompson, illustrated with geometrical models, happened unheralded but much applauded in the middle of one informal concert. A bald mention of golf, tennis, rounders, dancing, chess, and an excursion to the Highlands must conclude this account.
