How are computers programmed with ones and zeros? Oct 07, 2024

Show notes

Computers can do all sorts of amazing things, from solving complicated math problems to showing us videos of dancing birds.

We asked computer engineer Sam Dickerson to help us find the answer.

Why do fevers give you chills? Sep 23, 2024

Show notes

Sometimes when we get sick, our body reacts by cranking up our internal temperature to make a fever. This helps get rid of invading bacteria or viruses. But sometimes when you have a fever, you feel cold instead of hot. What’s up with that? We asked ER doctor Joe Alcock to help us find the answer.
