Then, in quick succession two more particles were found, the neutron and the positron. Moreover, two particles whose existence has never been experimentally demonstrated cropped up in the lucubrations of theorists: the negative proton and the neutrino. Some of these little entities were charged with positive electricity, some with negative; some were electrically neutral or inert. Some were "heavy" or massive in relation to others-the ratio being about that of a ton to a pound. The physicists wound up. for the time being, with a nicely balanced table of discovered and hypothetical basic particles of matter, as follows...

Einstein's Relativity was practically complete in 1915, and Quantum Mechanics had its fullest flowering in the 19205. Since then, theoretical physics has been bogged down in ever-deepening sinks of paradox and abstraction, while experimental physics has forged gaily ahead, with the discovery of the neutron and positron, of artificial radioactivity, of heavyweight hydrogen...
Scarcely did the Harvard men announce this news to the American Physical Society in Washington than from Pasadena came word that Dr. Carl David Anderson of California Institute of Technology, Nobel Prize-winning discoverer of the positron, had independently discovered the new entity in his laboratory...
