YORK Pays to Do Conventional Things to salaries member and of to a on to circuit. By WATSON DAVIS Director, Science Service The physicists have nearly as much trouble naming a new fundamental particle as a family of f o n d parents, grandparents and^ in-laws deciding* what to call new baby. Now it is the heavy electron, the particle that lives only about a millionth of a second after being born " of the cosmic rays..that is being christened enthusiastically. Americans are calling the heavy electron "bary- Lon," the first part of the word 3eing Greek for "heavy." But Europeans, with Prof. Niels Bohr, cf Copenhagen, as chief protagonist, are using "yukon" in honor of the Japanese physicist, Yukawa, who postulated the existence of the particle before Drs. C. D. Anderson and Seth Neddermeyer, of SCIENCE TODAY NEW COSMIC RAY PARTICLE--"BARYTON" OR "YUKON?" DAVIS Pasadena, discovered it in 1937. In discussion at the recent bridge meeting of the British sociation, one of the Americans present observed that yukc-n was a rather cold name for n particle ;o hotly discussed and that AJns- ans might protest. The heavy electrons seem to make up the major portion of penetrating particles resulting from the cosmic radiation-. Scientists are flying high into the atmosphere and setting up apparatus deep in tunnels in order to study them. With some 240 times the muss sf the ordinary electron, basic- unit of electricity, the heax'y electron is lighter than the proton, the nucleus of the hydrogen It may very well be triplets, it would be logical for it. to found with negative and positive charges as well as no charge at all. It is a very unstable creatuie, existing theoretically for a- mere millionth of a second when at rest. Strangely enough, it lives longer when it goes fast owing to the relativistic change in time. One of them by great good was photographed at Pasadena coming to rest. Heavy electrons are supposed to disintegrate into electrons and neutrinos. And neutrinos are particles postulated but not yet discovered. INDIA INCREASES IRRIGATION Simla, India (UP) --- The government is steadily enlarging the field of cultivation in India fay large-scale irrigation schemes. Areas under state irrigation now total 31,000,000 acres, or one- eighth of the total cultivable aren 01 British India, as compared only 10,500,000 acres in 1878-79.
