Look Who's Talking: Conference to Unite Language of Physicists Hopkins will host a four-day international conference next week that strives to unite physics, astrophysics and cosmology. The PASCOS/Hopkins Symposium on Particles, Strings and Cosmology will be March 22 to 25, at the Bloomberg Center for Physics and Astronomy. The conference will bring together experts in the fields of particle physics, cosmology, astrophysics and "string theory," which theorizes that elementary particles are not particles at all, but tiny loops of relativistic string. Scientists are being encouraged to write their lectures so that experts in other fields can understand the material, said Jonathan Bagger, a professor in the Department of Physics and Astronomy. "I'd say it's one of the few major conferences where people in the different fields actually try to sit down and talk to each other," Dr. Bagger said. The symposium combines two previously separate conferences. The Johns Hopkins Workshop on Particle Physics has been held annually for 20 years. The PASCOS Symposium has been held for the past five years. This year Hopkins was invited to host the PASCOS Symposium, so the conferences were combined. The interdisciplinary approach is a natural progression, since many of the sciences are intertwined. For example, high-energy particle physics is naturally linked to cosmology, since physicists recreate conditions that existed in the early universe, producing particles that existed at the dawn of time. Another example is string theory, which has deep connections to modern mathematics. Top scientists from around the world will deliver lectures during the conference. Most of the presentations will be held in the Schafler Auditorium. But one presentation, highlights from the Hubble Space Telescope, will be held at Space Telescope Science Institute.
