And Now the Neutron
With the discovery of the neutron, science now has one more physical entity to juggle with. Though some of the press appears several weeks ago to have given the impression that the neutron was a brand new lucky strike, physicists have suspected for years that some such thing was "hiding out" and if sought would sooner or later be brought to light by experiment. The accompanying discussion is more mature than it could have been had it been written earlier. It was especially prepared for the SCIENTIFIC AMERICAN by a writer, himself a Cambridge man, who is in close personal touch with the principals now engaged in the brilliant researches going on in the famous Cavendish Laboratory at Cambridge University, England.—The Editor.
