Edwin Mattison McMillan (September 18, 1907 – September 7, 1991) was an American physicist credited with being the first to produce a transuranium element, neptunium.For this, he shared the 1951 Nobel Prize in Chemistry with Glenn Seaborg.

Antielectron (or positron), the first antiparticle, discovered by Carl D. Anderson [13] (proposed by Paul Dirac in 1927 and by Ettore Majorana in 1928) 1937 Muon (or mu lepton) discovered by Seth Neddermeyer, Carl D. Anderson, J.C. Street, and E.C. Stevenson, using cloud chamber measurements of cosmic rays [14] (it was mistaken for the pion ...
Hilton Head Island in the summer of 2012 Live oaks with Spanish moss on Hilton Head Island. The Town of Hilton Head Island incorporated as a municipality in 1983 and has jurisdiction over the entire island except Mariner's Cove, Blue Heron Point, and Windmill Harbor. [76] The Town of Hilton Head Island has a Council-Manager form of government.
1897 J. J. Thomson discovered the electron; 1897 Emil Wiechert, Walter Kaufmann and J.J. Thomson discover the electron; 1898 Marie and Pierre Curie discovered the existence of the radioactive elements radium and polonium in their research of pitchblende; 1898 William Ramsay and Morris Travers discover neon, and negatively charged beta particles
The electron tube is replaced by a high vacuum in the glass flask with significantly improved properties. Alexander Meissner patented his process "feedback for generating oscillations", by his development of a radio station using an electron tube . The Englishman Arthur Berry submits a patent on the manufacture of printed circuits by etched metal.
Pais, Abraham ; Inward Bound – Of Matter & Forces in the Physical World, Oxford University Press (1986) ISBN 0-19-851997-4 Written by a former Einstein assistant at Princeton, this is a beautiful detailed history of modern fundamental physics, from 1895 (discovery of X-rays) to 1983 (discovery of vectors bosons at C.E.R.N.)
Anderson was born in New York City, the son of Swedish immigrants.He studied physics and engineering at Caltech (B.S., 1927; Ph.D., 1930).Under the supervision of Robert A. Millikan, he began investigations into cosmic rays during the course of which he encountered unexpected particle tracks in his (modern versions now commonly referred to as an Anderson) cloud chamber photographs that he ...
