DIFFERENTIAL AND. INTEGRAL CALCULUS by R. COURANT. The Mathematical Discoveries of Newton. By H. W. Turnbull, M.A., F.R.S.. 6s. 6d. net. VOLUME I. In this volume Professor Courant dis- cusses the more advanced parts of the. Calculus, such as the theory of functions of several variables and multiple integrals.

In the Nazi government dismissed Courant for being Jewish, and he emigrated to the United States. He found, in New York, what he called "a reservoir of talent" to be tapped. He built, at New York University, a new mathematical Sciences Institute that shares the philosophy of its illustrious predecessor and rivals it in worldwide influence. For Courant mathematics was an adventure, with applications forming a vital part. This spirit is reflected in his books, in particular in his influential calculus text, revised in collaboration with his brilliant younger colleague, Fritz John. As he was half-Jewish and his bride Aryan, he had to flee Germany in

The defeat in the First World War had demoralized large segments of society and had led to rampant inflation. Courant showed his resourcefulness by keeping things afloat, partly with the help of the far-sighted industrialist Carl Still. The first part, based on lecture notes of Hurwitz, was written from the Weierstrass point of view; its main subject was elliptic functions. Courant supplemented this material with nine chapters on Riemann surfaces, conformal mapping, and automorphic functions.

Courant used an informal, intuitive notion of a surface that displeased some readers but pleased others.

Two years later, in , the first volume of Courant-Hilbert appeared. The book starts with a page chapter on linear algebra, presented from an analytic point of view, so that generalization to infinite dimension comes naturally. This is followed by chapters on orthogonal function systems, the Fredholm theory of integral equations, the calculus of variations, and the vibrations of continuum mechanical systems, using extensively the spectral theory of self-adjoint ordinary and partial differential operators.

This was a striking example of mathematics anticipating the needs of a new physical theory. In Courant, Friedrichs, and Lewy published their famous paper on the partial difference equations of mathematical physics. The main motivation for writing it was to use finite difference approximations to prove the existence of solutions of partial differential equations. The paper discusses elliptic, parabolic, and hyperbolic equations; it con-tains a wealth of ideas, such as the probabilistic interpreta-tion of elliptic difference equations, and the restriction that has to be imposed on the ratio of the time increment and the space increment.

The latter, known as the CFL condition, became famous during the computer age. Woe to the computational scientist who ignorantly violates it. This is an outstanding example of research undertaken for purely theoretical purposes turning out to be of immense practical importance. It has been extremely successful in every sense; its translation into English by McShane has sold 50, copies of Volume 1 and 35, copies of Volume 2 in the United States.

It has shaped the minds of many who wanted and needed a deeper grasp of the calculus. Even after 70 years it is better than most, nay all, calculus books in use today in the United States. This caused some confusion after the Second World War, when the German government, to its credit, decided to compensate not only faculty members who were dismissed by the Nazis but assistants as well. In concrete negotiations were started, and plans laid, for housing the institutes of mathematics and physics in a permanent building, for long a dream of Felix Klein, now enthusiastically taken up by Courant.

The building of the institute was finished and dedicated in Courant became its director. Yet this moment of triumph already contained the seed of its own destruction, and that of most civilized Western institutions. The stock market in the United States crashed a few months earlier, leading to a deep economic depression that soon became worldwide.

The misery caused by this drove a sizeable part of the German voting population, already embittered by the defeat in the First World War, to support the Nazis.

In January the Hitler gang took over the government. It soon established a new age of barbarism in Germany. For a start, Jewish employees of the state, including professors, were dismissed summarily, Courant among the first. A chance encounter with a member of the Nazi party, who was a member of the university community, set him right.

Things will get worse and worse for you. You had better get out while you can. After a brief stay in England he, his family, and some family friends landed in New York, where thanks to Oswald Veblen and Abraham Flexner, a position was offered to him in the department of mathematics of New York University, with the charge to develop a graduate program. His host there was the mathematician Donald Flanders, admired by all for his saintly character.

He and Courant formed a deep friendship that today extends to their children. At NYU Courant found a mathematical desert. How he made it bloom is a fascinating story.

It started in with a burst of creative energy. Courant pursued these generalizations during the next 10 years. Friedrichs, and by James J. In the s, mid-career, he decided to seek a Ph.

One of the first courses he took there was by Heinz Hopf on geometry. Stoker was so charmed by the subject, and the teacher, that he switched his doctoral studies to differential geometry.

In What Is Mathematics? It ought to be compulsory reading for all who today are engaged in reforming the teaching of mathematics. To enable those who worked during the day to attend classes, graduate courses were offered in the evening, once a week, for two hours at a time. Courant was soon invited to be a member of this elite group.

The mathematical project at NYU sponsored by the OSRD was about the flow of compressible fluids in general and the formation and propagation of shock waves in particular.

There was also money to provide stipends for graduate students, some of whom were drawn into war work. Courant insisted that graduate training continue even during the war.

This is a good place to describe Courant as a classroom teacher. He seldom bothered to prepare the technical details of his lecture. He muttered in a low voice, and his writing was often indecipherable. Nevertheless, he managed to convey the essence of the subject and left the better students with a warm glow of belief that they could nail down the details better than the master. The bulk of the research conducted during the war was fashioned into a book on supersonic flows and shock waves.

He shrewdly realized that after the war the U. The critical contribution of science to the war effort had been noted by statesmen: radar, the proximity fuse, bombsights, code breaking, aerodynamic design, and the atomic bomb.

As always, he emphasized that research must be combined with teaching. When it came to hiring faculty, Courant relied on his intuition.

Courant did not like following fashions and fads. Courant did not extend his hatred of Nazis to the German nation.

He overcame his resentments and was eager to help those deserving help. He traveled to Germany as soon as it was possible, in , to see the situation there first-hand, to talk to people he trusted. The commission repeatedly replaced it with newer models; the last one was a CDC , installed in and put out to pasture in Courant retired in at age 70; his successor was Stoker.

In retirement Courant succeeded in finishing the translation into English of Volume 2 of Methods of Mathematical Physics. This was no mere translation. Courant made a serious attempt, with much help from younger colleagues, to update the material from a mere to over pages. The book ends with a page essay written by Courant on ideal functions, such as distributions. Relations Between Surface and Volume Integrals.

Differential Equations. Calculus of Variations. Functions of a Complex Variable. Back Matter Pages About this book Introduction The new Chapter 1 contains all the fundamental properties of linear differential forms and their integrals. These prepare the reader for the introduction to higher-order exterior differential forms added to Chapter 3. Extensive additions were made to the fundamental properties of multiple integrals in Chapters 4 and 5.

Here one is faced with a familiar difficulty: In order to minimize topological complications, only manifolds imbedded smoothly into Euclidean space are considered.

The notion of "orientation" of a manifold is studied in the detail needed for the discussion of integrals of exterior differential forms and of their additivity properties. On this basis, proofs are given for the divergence theorem and for Stokes's theorem in n dimensions.
