rubidium
- n a soft silvery metallic element of the alkali metal group; burns in air and reacts violently in water; occurs in carnallite and lepidolite and pollucite
- Well, if you had a suit made of rubidium canisters, you'd be invisible (except for the suit of rubidium canisters, of course).
- They started by barraging their rubidium atoms with lasers, slowing them to a crawl (heat is really just the motion of atoms and molecules; slowing therefore equals cooling).
- Cell phones, for instance, will receive a signal from a cell-phone base station, many of which often rely on commercially available rubidium atomic clocks.
