In the book From X-Rays to Quarks, the impressions and memories of Nobel laureate Emilio Segre regarding the development of modern Physics are presented.

Segre, without following a strictly chronological, historical approach to the subject, sketches the interesting and complex personalities of scientists who are often mentioned only in footnotes. Physicists, physics students, and those interested in the history of science will find that the book From X-Rays to Quarks significantly contributes to the understanding of scientists, with its thorough reference to many of the most attractive and intriguing topics in the field of physics.

Segre engaged as a researcher in Nuclear Physics and Particle Physics, was awarded the Nobel Prize for the discovery of the antiproton, and served as the head of a research team at the Los Alamos laboratory from 1943 to 1946.
