Abstract

I'm Professor of Physics at the University of Washington in Seattle . I do basic research in ultra-relativistic heavy ion physics with the STAR experiment, using the RHIC facility at Brookhaven National Laboratory, colliding gold nuclei to produce systems that look something like the first microsecond of the Big Bang. I do not work much in cosmology and astrophysics, although I've published a paper or two in those areas, but I do write a bi-monthly science column for Analog Science Fiction/Fact Magazine . One of my columns was entitled BOOMERanG and the Sound of the Big Bang " and was published in the January-2001 issue of Analog. It described the then-recent Antarctic balloon flight that mapped the small-angle temperature variations of the cosmic background radiation. Following the lead of the scientists involved in the project, I described the temperature variations they observed as, in effect, a recording of the "sound of the Big Bang" when the universe was 376 thousand years old.
