NIST: Bose-Einstein Condensation in Dilute Atomic
the most energy are ejected from the magnetic trap. The remain-ing atoms have, on average, less energy per atom, and are therefore colder. After evaporation has cooled the atoms to a temperature perhaps another factor of a hun-dred colder than the laser-cooled sample, the condensate be...

the independent dating of the artifact types is reliable, this can be considered a calibrated relative dating method. Old World artifact types used as time markers atomic mass the mass number of one atom of an isotope (e.g., carbon-14). It is the sum of the masses of the protons, neutr...

types of aurora and remove the bright geocorona emissions from the images. The Geocorona Photometers will observe the distribution of the geocorona emissions to derive the magnetospheric hydrogen content responsible for neutral atom generation in the magnetosphere. Three other t...
The Wizard's Lab : Magnetism
substances are magnetic is very complex. It has to do with the electron spin in an atom. In fact, there are only three substances in the world that can become magnetic: Iron, Nickel, and Cobalt. Now these materials can either come out of the Earth mag...

Lasers, Magnets, and the Coldest Stuff in the Univ
however, physicists began to develop cheaper and more sophisticated methods of cooling atoms and keeping them isolated from their environments. Laser cooling was one of these new methods. Like all light, a laser beam is made up of individual particles of light called photons. Each photon has momentu...
