Great writing

"The most unmistakable chemical transformation is that of a matter's state – a solid liquefies, a liquid evaporates, a vapor condenses into rain. For most of the furnishings of our everyday life, we associate a particular substance with only one of those three states. Wood, steel, and stone – solid. Oxygen and helium – gas. Alcoholic beverages – liquid (you can keep a bottle of Bombay Sapphire in the freezer, and somehow it remains an ever pourable starter to a gin and tonic). Water again bucks convention and seems almost equally at home in all three forms, as ice, steam, and liquid. In fact, Earth is exceptional in its possession of tristate water. Mars has a lot of water, but it's frozen away underground. Jupiter and Saturn have traces of water, too, but as orbiting ice crystals or a gas among miasmic gases. Only on Earth are there ocean flows and Arctic floes and sputtering Yellowstone fumaroles; only the Goldilocks planet has water to suit every bear."

  1. Hugh Wadman, chemistry prof at Raymond College, pointed out how different everything would be if not for the fact that one common chemical compound in our world is an exception to the general rule, and is lighter in its solid state than in its liquid state. The compound is H2O — water. If the solid state were heavier, bodies of water would freeze from the bottom up instead of the top down. In very cold interludes, life forms would be left exposed on top of the ice, rather than cold-but-sheltered at the bottom. And very different life forms (if any) would have evolved.
