McDonald's says it opened the cafe to see if a town too small for a regular franchise could support a traditional restaurant. But it has no plans for future golden-oldie branches. The cafe is not the only experiment the Big M has launched in recent months. The company...
Growing up in Shelby, Mont., Horner collected his first dinosaur fossil at the age of eight, and he set out in high school to become either a paleontologist or the next Wernher Von Braun. His schoolwork was wretched, but he excelled at science projects. One, presented to a small group...
Since 1968 scientists have been monitoring huge detectors for signs of these fleeting visitors from the sun. But so far, the results have been both disappointing and intriguing: the experiments have detected far fewer neutrinos than solar models predicted. Scientists were especially baffled by a recent report from a Soviet...
The case of the missing solar neutrinos has stirred growing excitement in the physics world. There are three possibilities: the Baksan experiment is wildly wrong, scientists don't understand the sun as well as they thought they did, or scientists have underestimated the elusiveness of the neutrino. The answer to...
...Experimental evidence indicates that neutrinos come in three varieties: the electron neutrino, the muon neutrino and the tau neutrino. Solar fusion gives off the electron type. Bahcall and Bethe speculate that electron neutrinos change into the muon or tau versions somewhere between the sun and Earth. "It's as if they started out sweet," marvels Bethe, who won the Nobel Prize in 1967 for explaining how nuclear fusion powers the sun, "and then suddenly turned salty." Thus the Baksan experiment may have come up empty- handed because it was not designed to detect muon or tau neutrinos...
