Here’s What’s Missing from a High School Physics Education

If you want to be a world leader in science and technology, it’s important that your kids learn all about the science that makes technology work, right? Physics forms the backbone of our understanding of the universe, but our high school physics curriculum are more than a little lacking when it comes to things from the past 150 years. More »

How Can We See Light? [Video]

Light is tricky. You probably know that we experience “light” by seeing it bounce off something before being absorbed into our eyes. But what about light itself? That’s much tougher, since in order to see the light, it has to be absorbed. Solving for this little Catch 22 won Serge Haroche the 2012 Nobel Prize in physics. More »

How Real-Life Physics Fakes Telekinesis [Video]

We all know telekinesis can’t be real. As hard as you try, you can’t will the remote into your hand from five feet away, at least not in this reality. But still, all kinds of seemingly telekinetic forces operate around us all the time. How do they do that? More »

How To Simulate the Universe On Your Laptop [Video]

The universe is a huge, complex, beautiful-yet-terrifying place, and we’ve spent a lot of time studying it. While some of the more complex models of the universe call for super-computers and tons of processor power, MinutePhysics has one you can run on your laptop. More »

Guns in Space, and How to Kill Our Sun [Video]

MinutePhysics showed us what would happen if the Earth were hollow, but that was just one part of the nerdy YouTube channel tag team this weekend. Here’s the other half, wherein we learn how big a gun you’d need for the bullet to orbit the moon and hit you in the back of the head, and how to put out the Sun. (Please don’t actually put out the Sun.) [YouTube] More »

Which Olympic "Throwing" World Record Required the Most Power? [Video]

The Olympics are full of beefy men and women throwing heavy things long distances. That’s just good television. But which event takes the most power to compete in? MinutePhysics broke down the numbers for the world records in the shot put, javelin, discus, and hammer throw. (Spoiler: It’s called the hammer throw. What did you think was going to win?)
