...moralist, for whom Mr. Santayana, unlike Mr. T. S. Eliot, does not cherish an excessively warm regard. There is, as the third essay, a highly suggestive consideration of the theory of relativity and the new physics. The suspicion is advanced that "even Einstein is an imperfect relativist, and retains Euclidean space and absolute time at the bottom of his calculation, and recovers them...
...Professor Coolidge started his literary career by writing "Elements of Non-Euclidean Geometry; in 1916 "Treatise on the Circle and the Sphere"; in 1924, "Geometry of the Complex Domain"; and in 1925, "Introduction to Mathematical Probability...
...Einstein world is a great "field" which has height, breadth, depth and time as its elements. Measuring those four elements requires a new kind of geometry?fourth dimensional geometry, Einstein geometry. It is infinitely more complicated than Euclidean geometry taught at high schools and colleges...
...obliged to re-examine his whole world and to remeasure it. Euclidean methods of measurements were only approximate. So, too, were Riemannian...
Mathematics 18, on the elementary theory of Differential Equations, and Mathematics 30, an introduction to partial differential equations, are new half-courses. A full course, Mathematics 29, dealing with non-Euclidean Geometry, is also offered for the first time...
