Plethora of Particles. For years physicists have been confused by the largely accidental discovery of more and more particles. They appear in the smashed-up debris of collisions between other particles, and they show up clear and sharp on bubble-chamber pictures and other detection devices. By the time about 100 such bits of matter had been found, physicists began to doubt that they were really elementary. Questions arose. Were some of the particles merely "states" of other particles, differing in only minor ways? Were they all just combinations of a few really elementary particles? No one knew for sure...
...apparatus was built around the 33-bev (billion electron volt) Alternating Gradient Synchrotron, and it used a line of magnets and electrostatic separators 400 ft. long to isolate negative K-mesons. Ten of the K-mesons were allowed to enter Brookhaven's 80-in. liquid-hydrogen bubble chamber every 2½ seconds, and pictures were taken of the results. Two pictures out of 100,000 showed tracks in the LH2 that proved to be the "signatures" of omega-minus particles. They all curved just right and took off in the right directions. Careful calculations with a computer gave...
...thing, he spends much more money on adornment than his father ever did; a recent survey by E. I. du Pont de Nemours & Co. shows that the average college man spent $387 on clothes last year, compared with only $265 for members of the Junior Chamber of Commerce, who were 15 years older on the average. For another thing, the young man is apt to be fad-prone...
...proper stranger were still disgruntled over the manner in which the affair had been handled by The Netherlands' government. The nation especially resented seeing popular Queen Juliana humiliated when she first announced that the engagement was off and then had to eat her words. In the lower chamber of Parliament, beleaguered Cabinet ministers eventually found a convenient scapegoat in the government information service, and promised in the future to improve communications between palace and public...
...city's 198 psychiatrists, or approximately one to every 166 residents (compared with the national average of one per 1,100). There is no heavy industry and no effort to attract any. There are 22 banks, nine hotels, the cleanest jail in the county, and a chamber of commerce that couldn't care less. There are 65 acres of parks and playgrounds but no pool hall; a fencing academy but no laundromat or bowling alley...
