Abstract
Until recently it was generally believed that all matter condenses as the temperature is reduced. With the exception of helium the condensed state is ultimately a solid. (Helium forms a liquid at 4.2 K, but resists solidification under its own vapor pressure down to absolute zero.) Now, however, it is known that one substance will remain gaseous at artibrarily low temperatures. As the tern-is reduced it will form a new state of matter, a quantum gas displaying such unique phenomena as Bose Einstein condensation and gaseous superfluidity.
