The discovery that simple, common magnesium diboride can conduct electric current without resistance and does so at a surprisingly high temperature has sent physicists racing to understand its properties and to try to improve upon them. (p. 134)

Dracula doesn't want to suck your blood. He wants you to enter his online library and learn about the properties of light, waves, and particles. Here at "The Atoms Family" Web pages, created by the Miami Museum of Science, Dracula and four other silver-screen ghouls invite Web surfers into their laboratories to try out physics experiments geared to children from kindergarten to grade 12.Go to: http://www.miamisci.org/af/sln/index.html

Ordinarily in continuous motion, light pulses come to a dead stop in specially prepared atom clouds. (p. 52)

By making the densest, hottest matter ever in a lab, smashups between fast-moving nuclei in the Relativistic Heavy Ion Collider are coming closer than ever to reproducing the superhot, primordial fluid that presumably filled the universe immediately after the Big Bang. (p. 63)

Researchers in Japan have made a material whose inherent magnetism can be turned off and on electrically, as long as the material, a novel semiconductor, stays ultracold. (p. 63)
