Baseball reporters say that long fly balls that would have carried for home runs in July "die" in the cool air of October and are caught. The idea behind this observation is that a baseball carries
The laser beams are tightly focused. They briefly (for 0.5s) exert enough pressure to confine 500sodium atoms in a vloume of 1.0x10^-15m^3. The temperature of this gas is 0.00024K, the lowest temper
Using a ground-based telescope and a spectrometer, it has been found that sodium vapor is a major component of the thin atmosphere of Mercury. Its concentration is estimated to be about 1.0x10^5 ato
