Theory of Everything - What is Matter?
What is matter, anyway? What does it have to do with math? And why aren't you made of Jesus? Delving deeper into the theory of (almost) everything - the Standard Model of particle physics.

Magnets: How Do They Work?
How do magnets work? Why do they attract and repel at long distances? Is it magic? No... it's quantum mechanics, and a bit more, as we explain in this, the longest MinutePhysics video ever.

Four Weird Ways to Make Electricity
When you think of newer ways to make electricity, solar cells and wind turbines may come to mind. But scientists can make the stuff from just about anything. And they're working on some truly bizarre ways to generate power.

The Moon is Rusting. It's the Earth's Fault.
The Moon is typically 380,000-ish kilometers from the Earth, so it doesn't seem like they have that much of a direct influence on one another. However, the presence of hematite on the lunar surface suggests our planet is causing the Moon...

Does Antimatter Fall?
In September 2023, a group of scientists from CERN published the first results from the ALPHA-g experiment, which seeks to figure out how antimatter responds to the force of gravity. Does it fall like regular matter? Does it not interact...

Mercury Shouldn't Be Liquid. But It Is.
Mercury, a.k.a. quicksilver, is famous for being a liquid at room temperature...and also below room temperature. But you can't use a high school chem class to explain why. Instead, we need a little help from Einstein.

The Electric Light Bulb Was Invented Centuries Before Edison
Thomas Edison often gets credit for the invention of the light bulb, but a good argument can be made that they were around centuries earlier in the form of barometric light.
