The Impossibility of Perpetual Motion Machines
Bad ideas come and go in physics. But there’s one bit of nonsense that is perhaps more persistent than all others: the perpetual motion machine. No working perpetual motion machine has ever been experiment verified. All break the laws of...

The Fastest Animals Are Way Faster Than You Think
The fastest animal in nature isn't what you think it is. It's way, way smaller than that. Nature's tiniest creatures warp the laws of physics, and they do it in ways that even human engineers would gawk at. Using the power of super...

TED-Ed: This is what happens when you hit the gas | Shannon Odell
In 2015, two men drove a Volkswagen across the US on just over 100 gallons of fuel. Their 81-mile-per-gallon performance doubled the car's estimated fuel rating, and set the record for the lowest fuel consumption ride of a diesel car....
