Why do chemicals have to be heated in the flame first before the colored light is emitted?
Professor James Wolfe received his Ph.D. in physics from the University of California, Berkeley, in 1971. His thesis work involved a new technique in high resolution NMR, and optical polarization and maser action of nuclear spins. He remained at Berkeley as an assistant research physicist until 1976, when he joined the Department of Physics at the University of Illinois. He is a renowned expert on the imaging and thermodynamics of excitonic matter in semiconductors. His 1998 book, Phonon Imaging , describes the propagation of phonons and ultrasound in solids. A Fellow in the American Physical Society, Professor Wolfe has headed multi-investigator programs for the Department of Energy and the National Science Foundation. He was awarded the 2004 Frank Isakson Prize for Optical Effects in Solids of the American Physical Society "for contributions to the fundamental understanding of excitonic matter and ballistic phonons in semiconductors, made possible by pioneering development of graphic imaging techniques."
Professor Wolfe has written the book "Elements of Thermal Physics", used in the Department's core curriculum for engineering and science majors. He was honored with the Paul Klemens Award in 2010.
