Forewords by Henry Margenau and Sir Karl Popper. (illustrator). Very Good (little edgewear covers; contents clean & tight). Small quarto: blue & white printed wraps; 194 pages First Edition. Signed presentation from Koga on half-title page: ?For Professor George E. Uhlenbeck, With my best compliments, Toyoki Koga.? Toyoki Koga was a prominent physicist who was behind the turbulent changes in attitudes to quantum theory in the second half of the 20th century. George Eugene Uhlenbeck was a Dutch-American theoretical physicist, who developed the physical theory of the Ornstein-Uhlenbeck process. n 1927, Uhlenbeck took a position as an instructor in physics at the University of Michigan in Ann Arbor. He stayed there until 1935, when he succeeded H. A. Kramers as a professor of theoretical physics in Utrecht. During his eight years in Ann Arbor, Uhlenbeck organized the noted "Summerschool" in theoretical physics. A scarce book, this copy, particularly, notable for the association between two major physicists of the day. Signed.

Koga, Toyoki (1912- ). A method of solving boundary value problems of irrotational gas flow by means of digital computers. Dittoed typescript. N.p., n.d. [ca. 1956]. Unbound. [1], 11ff. 281 x 218 mm. Provenance: Theodore von K rm n. Koga's presentation inscription to Theodore von K rm n on the title-leaf: "To Professor T. von K rm n with the author's best compliments. Toyoki Koga." Small rust-mark from paperclip, a few spots. "A method of solving boundary value problems of gas flow where sub-sonic, sonic and super-sonic areas appear simultaneously is proposed. Being given a stream line and the state on it, the coordinates of the neighboring second stream line and its state are calculated according to the fundamental equations of gas flow. . . . By means of modern digital computers, we may easily obtain results of sufficient accuracy" (first leaf). Contrast this approach with the solution to a related problem presented thirteen years earlier in item by Kormes. Origins of Cyberspace 755.
