JF Ptak Science Books Post 1838
The data and research and linkage below are taken entirely from the Chronology of Milestone Events of Particle Physics, streamlined and adapted and made a little more accessible (for me) for a fast browse–I’ve had no hand in assembling this data, just re-arranging it.
The links are quite valuable–the scientist’s biography is clickable on the name, and the article is reproduced from the original in the pdf.
