miso soup
ever watch miso soup cool? it makes really pretty patterns. bored with that one? mix it up again and wait. you'll get a completely different pattern. some parts of the soup are slightly warmer than others. the differences get amplified into the rising and falling areas that are so visible. i could write a computer program to simulate miso soup. i'd never duplicate exactly what happens in any one given bowl on any given day. it would be silly to have that expectation. i can however predict how the convection affects how fast the soup cools. a similar thing happens with climate models. you can't accurately predict if your property is going to cook or cool. it's silly to have that expectation.
