Electrons DO NOT Spin
Quantum mechanics has a lot of weird stuff - but there’s thing that everyone agrees that no one understands. I’m talking about quantum spin. Let’s find out how chasing this elusive little behavior of the electron led us to some of the...

Is Earth's Magnetic Field Reversing?
Earth’s magnetic field protects us from deadly space radiation. What if it were drastically weakened, as a precursor to flipping upside down? I mean, it has before … many, many times.. Spaceship Earth has a literal deflector shield. A...

What's the Most Realistic Artificial Gravity in Sci-Fi?
2001: A Space Odyssey introduced a lot of people to the idea of rotation based artificial gravity, but in sci-fi, it’s far from the only one to implement the idea! Babylon 5, Halo, and Ringworld also used rotation-based artificial...

Do We Need a Negative Leap Second?
Did you know that last year we had 28 of the fastest days ever recorded? Earth's rotation can be affected by a number of things, and scientists think we might someday need an unprecedented adjustment: deleting a second!

What is Wind?
We all know that warm air rises, but how does this scientific fact influence our weather and create those flows of air molecules that we know of as wind? In this episode of SciShow, Hank explains where wind comes from, what factors...

Why December Has The Longest Days
December has the longest solar days (noon-to-noon) because of the weird way a combination of the axial tilt of the earth and the eccentricity of its elliptical orbit conspire in December. Perihelion + Solstices = Long Days.
