About Temperature


Temperature is Important!

Temperature is the most important single thing in your life! You don't believe it - then think about it!

Temperature is a fundamental part of life. On the open ended temperature scales (there appears to be no upper limit to temperature), biological life as we know it functions over a very small environment range of about -30°C to perhaps 120°C. The known temperature range occurring naturally in the universe is from -269°C to perhaps 40,000,0000°C in a star. It is estimated that less than one billionth of the matter in the universe in in the biologically friendly temperature range.
