Declination
... The sign is customarily included even if it is positive. Any unit of angle can be used for declination, but it is often expressed in degrees, minutes, and seconds of arc. A celestial object that passes over zenith has a declination equal to the observer's latitude. A pole star therefore has the decl ...

Avogadro`s Number
... Avogadro’s number is almost incomprehensibly large. For example if one mole of dollars was given away at the rate of a million dollars per second beginning when the Earth was first formed some 4.5 billion years ago, would any remain today? Surprisingly, about three fourths of the original mole of do ...
