...momentous experiment was led by Columbia Professors Leon Lederman, Melvin Schwartz and Jack Steinberger, and helped by Brookhaven scientists in charge of the synchrotron. First step was to shoot the machine's high-energy protons at a beryllium target and produce an intense beam of pions-which decay rapidly into muons, neutrinos (perhaps the new type), and other nuclear odds and ends. After shooting across some 70 ft., this beam of mixed particles hit a shield of battleship armor 42 ft. thick that stopped everything but the neutrinos, which sailed on unheeding...
When one thinks of Boston, it is hard not to think of death and decay, decline and fall. Before we drop our tokens into the subway turnstyles and begin our survey, let me tender a well-meant suggestion that this matter of cemeteries recalls to mind. If you chance to take ill during the Summer School, ask to be admitted to Massachusetts General Hospital, a fine place whose chief interest for us here is that the view of Boston from its roof is about the best in town. If you stay well, you can't possibly get up there...
...appetite. But the kid is right and his mother is wrong, says Dental Surgeon Howard R. Raper of Albuquerque. Sweets eaten at the beginning of the meal leave little sugar in the mouth, because later courses scour it away. And sugar remaining in mouth crevices promotes tooth decay...
Even a child who is normally a "red reactor" with decay-prone teeth will show a blue reaction immediately after a good brushing. Those who eat their desserts first are not nearly so likely to need a toothbrushing for relative safety...
...major cultures: ancient Egyptian, ancient Semitic, Peruvian, Chinese, Mexican, Middle Eastern, Greco-Roman and Western. All had flourished for the same amount of time (about 1,000 years). All showed the same development. By comparing the dead to the living, the historian could tick off the inevitable signs of decay and predict how death would come again...
