ZZZZZzzzz.... *snort* Uhhhhh?
I have a problem getting to bed at a decent, or at least reasonable, hour. I've been up til 4-6 AM way too much lately o_O *waits for Raina to put the smackdown on me*

While lying in bed, I was watching Nova on PBS. It was an episode about the scientific discoveries that led to air conditioning and refrigeration. They had quite a few interesting tidbits of information on there:

- When Celsius came up with his temperature scale, he originally had it backwards with boiling at 0 and freezing at 100. It was after his death that Swedish botanist Carolus Linnaeus reversed the scale.

- Around the end of the 18th century, Antoine Lavoisier proposed a theory that heat was actually a substance, a liquid he referred to as 'caloric'. Heat was generated when this substance flowed into an object and between its molecules.
It wasn't until the mid 19th century that the correct theory, heat being generated from the motion of an object's atoms, was officially recognized, and the caloric theory persisted almost until the 20th century.

Hope you enjoyed the science lesson ^^
