Be Smart

We give you deep answers to simple questions about science and the rest of the universe. And also dad jokes.

Be Smart is hosted by Joe Hanson, PhD. He’s a molecular biologist and an award-winning science communicator and journalist

Ever gone down a rabbit hole wondering why the sky is blue and ended up learning about quantum mechanics at 2am? That’s basically every Be Smart video.

Joe Hanson has a real PhD, and it shows in every video,, but you’ll still watch three in a row at midnight.

He covers everything from the weird biology of sleep to why time feels faster as you get older, and somehow makes you care about all of it. You finish each video feeling like you actually learned something rather than just watched something.

The dad jokes are bad. Watch it anyway.
