Ted: Ted Ed: Einstein's Brilliant Mistake: Entangled States
When you think about Einstein and physics, E=mc^2 is probably the first thing that comes to mind. But one of his greatest contributions to the field actually came in the form of an odd philosophical footnote in a 1935 paper he co-wrote-...

Ted: Ted Ed: If Matter Falls Down, Does Antimatter Fall Up?
Chloe Malbrunot investigates matter and anti-matter by placing two atoms- one made of matter, and the other antimatter- in the cockpit of a plane, ready to jump. What do you think will happen? [2:54]
TED Talks
Ted: Ted Ed: Cloudy Climate Change: How Clouds Affect Earth's Temperature
As the Earth's surface temperature gradually rises, it has become vital for us to predict the rate of this increase with as much precision as possible. In order to do that, scientists need to understand more about aerosols and clouds....

Veronica Bindi explains what cosmic rays are, and how they transmit information about our universe from the great beyond. [4:40]
TED Talks
Ted: Ted Ed: Where Do Genes Come From?
When life emerged on Earth about 4 billion years ago, the earliest microbes had a set of basic genes that succeeded in keeping them alive. In the age of humans and other large organisms, there are a lot more genes to go around. Where did...
TED Talks
Ted: Ted Ed: What Is the Heisenberg Uncertainty Principle?
The Heisenberg Uncertainty Principle states that you can never simultaneously know the exact position and the exact speed of an object. Why not? Because everything in the universe behaves like both a particle and a wave at the same time....
TED Talks
Ted: Ted Ed: Particles and Waves: The Central Mystery of Quantum Mechanics
One of the most amazing facts in physics is that everything in the universe, from light to electrons to atoms, behaves like both a particle and a wave at the same time. But how did physicists arrive at this mind-boggling conclusion? Chad...
TED Talks
Ted: Ted Ed: Two Objects Same Room Two Different Temperatures?
How can two objects have the same temperature but feel like they have different temperatures? Veritasium explores this phenomenon. [4:00]
TED Talks
Ted: Ted Ed: The Science of the Game of Thrones

TED Talks
Ted: Ted Ed: What if the Earth Stopped Spinning?
Michael Stevens of Vsauce looks at what would happen if the Earth stopped spinning. He also explores how we construct time as a function of the Earth's rotation and why atomic clocks are so precise. [9:44]
TED Talks
Ted: Ted Ed: Why Does the Sun Really Shine?
Our assumptions about the world often evolve. The rock band, They Might Be Giants, discovered this firsthand. The band has covered the 1950s song, Why Does the Sun Shine?, since 1983. In 2008, they discovered the 1950s science, which the...
TED Talks
Ted: Ted Ed: Feedback Loops: How Nature Gets Its Rhythms
Anje-Margriet Neutel describes some common positive and negative feedback loops, examining how an ecosystem's many loops come together to make its 'trademark sound.' [5:11]
TED Talks
Ted: Ted Ed: What Can Schrodinger's Cat Teach Us About Quantum Mechanics?
One great example of quantum physics' weirdness can be shown in the Schrodinger's cat thought experiment. Josh Samani walks us through this experiment in quantum entanglement. [5:24]
TED Talks
Ted: Ted Ed: How Do Tornadoes Form?
Meteorologist James Spann sheds light on the lifespan of tornadoes as they go from supercell thunderstorms to terrible twisters before eventually dissolving back into thin air. [4:11]
TED Talks
Ted: Ted Ed: The Secret Lives of Baby Fish
The larvae of coral reef fish are capable of drifting thousands of miles on ocean currents, far from the reefs where they were born. Amy McDermott describes how these tiny trekkers travel across vast oceans, searching for the far-flung...
