    Sadly, I cannot remember which YouTube video featured this: But a guy basically speedran the description of how to solve a quadratic equation the Babylonian way, that is, drawing squares and circles and shit. It took quite a while for him just to list the steps. All that disappears once you learn the formula with the bad, scary letters.

    But sugar dissolves in cold water. It just takes a bit longer. This is 9th grade chemistry. At 20°C 203.9g sugar are soluble per 100ml of water.

    [Edit: Sorry, for the Americans here: At 68°F, 1 cup of sugar is soluble in 21/50 cups of water.]
