What is the universe made of?
AdultsHistoryPhysicsSpaceThe atoms around you have existed for billions of years -- and most originated in the flaming, gaseous core of a star. Dennis Wildfogel tells the captivating tale of these atoms' long journeys from the Big Bang to the molecules they form today.
The Truth About Toilet Swirl
AdultsPhysicsWorldWe each repeated the experiment 3 times, and got the same results every time. For those of you who might be skeptical, great! A right circular prismatic kiddie pool is only $10 and you can do the experiment for yourself at your latitude. There's really no reason you shouldn't do it for yourself.
The Essentials of Energy
AdultsPhysicsScienceEnergyTechnologyEnvironmentThe world of energy is a confusing place. What's better, nuclear or solar? What's the difference between fluorescent bulbs and LEDs? What's the difference between energy and power? And what the heck is a kilowatt-hour?!
How batteries work
AdultsHistoryPhysicsTechnologyScienceEngineeringBatteries are a triumph of science-they allow smartphones and other technologies to exist without anchoring us to an infernal tangle of power cables. Yet even the best batteries will diminish daily, slowly losing capacity until they finally die. Why does this happen, and how do our batteries even store so much charge in the first place? Adam Jacobson gives the basics on batteries.

Just how small is an atom?
AdultsPhysicsScienceEducationJust how small are atoms? And what's inside them? The answers turn out to be astounding, even for those who think they know. This fast-paced animation uses spectacular metaphors (imagine a blueberry the size of a football stadium!) to give a visceral sense of the building blocks that make our world.
The beginning of the universe, for beginners
AdultsHistorySpacePhysicsScienceAstronomyHow did the universe begin -- and how is it expanding? CERN physicist Tom Whyntie shows how cosmologists and particle physicists explore these questions by replicating the heat, energy, and activity of the first few seconds of our universe, from right after the Big Bang.

What Color is the Universe?
AdultsPhysicsSpaceAstronomyScienceWhen you stare up at the night sky, you might think that the universe is really black, but that's just because our eyes aren't sensitive enough to see the billions and billions of multicolored stars out there. Ever wonder why certain stars are certain colors? And what color is our sun, really? If we looked at enough stars, could we figure out the average color of the universe?

Dark matter: The matter we can't see
AdultsPhysicsSpaceScienceAstronomyThe Greeks had a simple and elegant formula for the universe: just earth, fire, wind, and water. Turns out there's more to it than that -- a lot more. Visible matter (and that goes beyond the four Greek elements) comprises only 4% of the universe. CERN scientist James Gillies tells us what accounts for the remaining 96% (dark matter and dark energy) and how we might go about detecting it.
If superpowers were real: Super speed
AdultsHumanPhysicsScienceEntertainmentWhat if super speed wasn't just the stuff of epic comic book stories? Is it scientifically possible to be super speedy? In this series, Joy Lin tackles six superpowers and reveals just how scientifically realistic they can be to us mere mortals.
