...operation, raised more problems than they have solved. One of their most baffling stunts was to produce the K meson, a short-lived particle knocked out of atomic nuclei. In all significant ways K mesons are alike, but some of them, called "tau K mesons," decay into three pi mesons; others, called "theta K mesons," decay into only two pi mesons. For mathematical reasons which physicists can explain only to other physicists, this inconsistent behavior seemed to violate the sacred parity principle. What could be done about it? The experimental evidence was plain, but it was hard to accept...

...crowded streets and candle-gleaming churches of Chicago and New York City, the Feast of St. John the Baptist was celebrated in high style last week.

For San Juan is the patron saint of the island of Puerto Rico, and the Roman Catholic Church...
...Spellman, New York's Mayor Robert Wagner, San Juan's Mayoress de Gautier and about 30,000 Puerto Ricans turned out for a Solemn High Mass on the terrace of Keating Hall. And then the fiesta began. Mayor Wagner opened it by shattering a king-sized earthenware piñata (filled with gifts) with a green-covered baseball bat, and both mayor and cardinal were promptly bowled over in the crush of a crowd to pick up souvenir pieces...
