    Inside the Lab That Protects You From Your Car

    Crashing a car is usually not a good idea. But sometimes, it can save lives. ↓↓↓ More info and sources below ↓↓↓ No one ever wants to get in a car crash. But if you ever do, be very thankful for the engineers who crash test cars. You may have seen crash test simulations on TikTok using physics engines like BeamNG but I promise you they are nothing compared to the real thing! Join us for this DEEP dive into the physics of car crashes and the ways that engineers hack Newton's laws to keep you safe.

    Sonic Hedgehog Gene - Why You Have Thumbs Rather Than Fins

    PBS Member Stations rely on viewers like you. To support your local station, go to: http://to.pbs.org/DonateOKAY ↓ More info and sources below ↓ Ever wonder why you have thumbs? Don’t miss our next video! SUBSCRIBE! ►► http://bit.ly/iotbs_sub The human hand, with its multi-talented thumb, might be man's greatest tool. But did you know we can trace that thumb, and the hand and arm it's connected to, all the way back to a 375 million-year-old fish named Tiktaalik? This week I sit down with paleontologist and geneticist Dr. Neil Shubin to learn what a fish, and a little blue hedgehog, can teach us about the evolution of thumbs. Be sure to watch Neil Shubin's special 3-part series "Your Inner Fish" on your local PBS station, premiering Wednesday, April 9 at 10 PM Eastern! http://www.pbs.org/your-inner-fish/home/ Also check out Neil's book "Your Inner Fish": http://amzn.to/1ssBCFt Joe Hanson - Host and writer Joe Nicolosi - Director Amanda Fox - Producer, Spotzen IncKate Eads - Associate Producer Katie Graham - Director of Photography Andrew Matthews - Editor and motion graphics John Knudsen - Gaffer Music: "Ouroboros" by Kevin MacLeod Produced for PBS Digital Studios ----------- Join us on Patreon! https://patreon.com/itsokaytobesmart Twitter http://www.twitter.com/DrJoeHanson http://www.twitter.com/okaytobesmart Instagram http://www.instagram.com/DrJoeHanson http://www.instagram.com/okaytobesmart Merch https://store.dftba.com/collections/its-okay-to-be-smart Facebook https://www.facebook.com/itsokaytobesmartpbs/​ Learn more about your ad choices.
