NASA’s cold atom lab
Today’s Video of the Day from NASA Goddard describes the Cold Atom Laboratory (CAL) on the International Space Station, which is colder than any known spot in the natural universe.
As the technology that we use every day becomes smaller and smaller, scientists must rely quantum physics to understand the nature of the particles that make up these devices.
By producing atoms a fraction of a degree above absolute zero, they are slowed down enough for experts to take precise measurements.
