Nobel Prize

  The Nobel Prize in Physics 2002             A NEW VIEW OF THE UNIVERSE Galileo Galilei discovered new worlds with his telescope. Over the centuries, a picture of a calm and stable universe emerged – the planets untiringly orbited the sun and the stars quietly burned their hydrogen into helium…

  The Nobel Prize in Physics 2002       Questions and Answers Related to the Prize       What is the mass of the neutrino? We do not know today if the neutrino has a non-zero mass or not. Recent results from experiments seem to indicate that neutrinos do have a very small…

  The Nobel Prize in Physics 2001       The density of the atomic cloud is shown, with temperature decreasing from left to right. The high peak, the Bose-Einstein condensate, emerges above the other atoms. The picture is from the JILA laboratory.       …coldest! Eric A. Cornell joined Wieman as a co-worker…

  The Nobel Prize in Physics 2001         To the left, Ketterle’s first interference pattern. The interference pattern between two expanding condensates resembles that formed by throwing two stones into still water.     Large condensates and interference patterns Wolfgang Ketterle came to the Massachusetts Institute of Technology (MIT) in 1990. He…
