BERKELEY, Calif., Nov. 21, 2012 — Stuart Freedman, an investigator of fundamental physical laws and a nuclear physicist with Lawrence Berkeley National Laboratory and the University of California, Berkeley, died unexpectedly Nov. 9 while attending a conference in Santa Fe, N.M. He was 68. Freedman used the radioactive decay of calcium atoms to rule out “local hidden variable” theories during his graduate work at UC Berkeley in 1972. He went on to exclude a number of other possible excursions from standard physics, including the existence of naked quarks, faster-than-light particles and very light Higgs...Read full article

    nuclear fusion
    In physics, nuclear fusion refers to the process in which two atomic nuclei come together to form a heavier nucleus, releasing a large amount of energy. This process powers the sun and other stars and is being researched as a potential clean and abundant energy source on Earth.
    photonics
    The technology of generating and harnessing light and other forms of radiant energy whose quantum unit is the photon. The science includes light emission, transmission, deflection, amplification and detection by optical components and instruments, lasers and other light sources, fiber optics, electro-optical instrumentation, related hardware and electronics, and sophisticated systems. The range of applications of photonics extends from energy generation to detection to communications and...
    quantum mechanics
    The science of all complex elements of atomic and molecular spectra, and the interaction of radiation and matter.
    spectrometer
    A kind of spectrograph in which some form of detector, other than a photographic film, is used to measure the distribution of radiation in a particular wavelength region.
