Millimeter of Mercury (also torr), a subsidiary unit of pressure used in measurements of atmospheric pressure, partial pressure of water vapor, and high vacuums. The notations are as follows: Russian,mm rt. St.;international, mm Hg. A millimeter of mercury is equal to the hydrostatic pressure...
1930 CE, rising to >460 kt in 1987 CE140. CFC releases have caused the Antarctic Ozone Hole, and their use is now banned under the Montreal Protocol. The combustion of coal, and historical gold and silver mining, has increased atmospheric mercury concentrations by ~450% over pre-...
I have left searing footprints on the dark side of the Moon. I have stood on the spires of Mercury, chilled by the solar wind. I have stretched my wings, and I have flown. That is what is possible when you understand the Sun's song. ...
Atomic Number: Atoms are made up of protons, neutrons, and electrons. The protons and neutrons are found in the nucleus of the atom, while the electrons are outside the nucleus. The atomic number is the number of protons, while the mass number is the number of protons and neutrons. If ...
Later, as the earth's span closed, the transferred minds would again migrate through time and space - to another stopping-place in the bodies of the bulbous vegetable entities of Mercury. But there would be races after them, clinging pathetically to the cold planet and burrowing to its ...
