,USC phys From Staff Reports In a revolutionary step in the world of quantum physics, a USC physicist is showing that the elusive waves of subatomic particles actually exist and could soon be observed in experiments. Although wave theory has been a part of physics for more than 50 years, a glimpse of the actual wave function whirh i? accrvinf/vl with particles like electrons, would be I remarkable. Most physicists have believed that the wave doesn't actually exist in a physical sense. Yakir Aharonov, already wellknown in physics for his Aharonov-Bohm Effect, has proposed a new interpretation of wave theory that describes subatomic particles and atoms as having an energy-like "intensity" that would be revealed and measured in experiments. A professor at USC and Tel Aviv University, Aharonov has | been a nominee for the Nobel Prize.

Physicists express that likelihood with mathematical tables containing wavy lines that describe the varying probability of a particle being a particular place. But, most physicists view the wave as something that s derived from the mathematics of probability, not as something that's real. Aharonov and two colleagues, Jeeva Anandan of USC and Lev Vaidman of Tel Aviv University, now say the wave doesn't exist as a mathematical table of probabilities, but it exists in a real and physical sense. "We are proposing an experiment where a single electron in an atom would be described as a single structure around the nucleus," Aharonov said. "It's an intensity surrounding the nucleus, and you can see the intensity of this wave." A theoretical physicist, Aharonov also has proposed a set of experiments that he expects will soon be performed by experimental physicists to reveal the wave funcel kills 13, said 45-year-old resident Minnie Byrd, who was reading in her third-floor room when she smelled smoke from the early morning fire. "I thought 1 had to jump, too. "I was praying real hard. I got one leg out the side and a fireman said, 'Wait! Wait!" and got the ladder to me." Some of the roughly 130 residents registered at the four-story Paxton Hotel were not accounted for by Tuesday afternoon. Rescuers used heavy equipment to search the rubble because the partially collapsed building was too dangerous to send searchers inside. Victims were on the ground, some shouting in pain, while firefighters concentrated on rescuing people rather than fighting the blaze. :rc. j... Again il4 art, by student activities fees.

"We've shown thai there is a new in type of experiment, which we call at a protective experiment, in which w these waves can actually be seen re existing in space. They're actual, th physical waves you can observe. vv The new interpretation also helps pi give deeper meaning to the wave aspect of particles like electrons, m protons, photons and odiers. One fu puzzling aspect of physics has been fa that particles behave like a particle at and a wave at the same lime. For example, if you shoot elec- A trons toward one another in a lab th under certain conditions, each par- di tide will exhibit the wave charac- th teristics of refraction and reflection, se Without this wave aspect, you th would expect particles to bounce w off one another like pool balls cf widiout showing any wave charac- tv\ teristics. er What's different about the exper- gj iments that Aharonov and his col- w< injures mor Robert Crowder, 61, said bars on the windows of his first-floor apart- be ment prevented him from escaping. of "There was no way to get out," \4 Crowder said.

Statistics show that about 0,000 people in the United ates acquire the hepatitis B rus each year and that about 300 people die from complica>ns annually. The disease is highly contaous through sexual contact, jpatitis B is 100 more times fectious than HIV, the virus at causes AIDS, said Karen lelly, USC's staff nurse in arge of hepatitis B training d immunization. While anyone is susceptible hepatitis B, young adults are greater risk if they are sexualactive, have unprotected sex multinle partners. have anoth sexually transmitted disease, are needles for injecting ugs, or work in health care. "Since many college students gage in high-risk sexual havior, it's really important r them to become vaccinated," elly said. The vaccine is given in the in in three doses over a six311th period. It rarely produces je effects, except mild soress in the arm, and it is not issible to contract hepatitis Dm the vaccine. The vaccine is relatively pensive, however, and is not >vered by most insurance ans. The vaccine costs $142 at e USC student health center d may be paid in three increents (at the time of each shot). For information on the hepati. B vaccine, college students ould call their campus health nter. Others should contact 2 county health department in eir area. itrGttMiody Molly WM!
