I understand how scientists use microscopes and telescopes and experiments, but how do they use computers?
A. With microscopes we can observe the very small; with telescopes we can see distant stars. An experiment can determine how chemicals interact. But microscopes and telescopes see only so far. Experimenting with all the myriad combinations of chemicals could take forever (and could lead to dangerously exothermic results that means explosions!). And some phenomena can’t be recreated in a lab you can’t create a model universe in a test tube!
