imagine a snowflake in your hand, and you look at it, and it's an incredibly complicated, beautiful object. But as you heat it up, it'll melt into a pool of water, and you would be able to see that, actually, it was just made of H20, water.
kuvitelkaa lumihiutale käteenne. Se on uskomattoman monimutkainen, kaunis objekti. Mutta lämmetessään se sulaa vesilammikoksi, ja näemme, että se on oikeastaan vain tehty H2O:sta, vedestä.
