A series of Stanford Univ. experiments had apparently verified the existence of quarks, hypothetical fundamental pieces of matter possessing fractional electric charges, the NY Times reported. Dr. William Fairbank, professor of physics at Stanford, described the findings-first evidence of quarks since their theoretical exposition in 1964-at the Am. Physical Society annual meeting in Washington, D.C. If matter consisted of protons, electrons, and neutrons (carrying charges of + 1, -1, and 0, respectively), quarks-the building blocks of these particles-would have fractional charges of +1/3, -1/3, +2/3, and -2/3. Fairbank emphasized that the results were not final, and that the university had scheduled follow-up tests. (NYT, Apr 27/77, A18)
