Robert F. Christy:  A Biographical Memoir
(with David L. Goodstein)

An early participant  in the Manhattan Project during World War II, Robert F. Christy played a leading role in the projects' Los Alamos, New Mexico, laboratory in developing the world's first nuclear bomb.

A History of Caltech

Caltech's beginnings are rooted in a modest little college founded in Pasadena in 1891 by wealthy former abolitionist and Chicago politician Amos Throop.  

Along with Enrico Fermi, Franco Rasetti played a key role in the rebirth of Italian physics in the 1920s and 1930s. In this interview he talks about his experiments at Caltech on the Raman effect in 1928–1929, mountain climbing, his passion for bugs, fossils, and flowers, and doing physics in Florence, Rome, Berlin-Dahlem, and Quebec. Rasetti also reminisces about the Rome school of mathematics and other scientists he has known.

A Talk: Gregorio Ricci Curbastro

The names of the Italian mathematicians Ricci and Levi-Civita have been enshrined in the theory of general relativity since Einstein seized on the absolute differential calculus as the indispensable mathematical tool for expressing his uniquely determined gravitational equations. The physicist’s long-standing indifference to mathematics changed abruptly as he struggled with the theory, methods, and notation of the calculus developed and refined by Gregorio Ricci Curbastro, together with Tullio Levi-Civita at the University of Padua, before the end of the 19th century. This talk is a brief introduction to the story of Ricci's life.
