NASA's new frontier, and the Trouble with "Gravity"
Hank describes how astronomers used a technique called gravitational lensing to find the most distant galaxy ever detected -- and how NASA is embarking on a new program to use this same technique to peer deeper into space than ever...

How Quantum Mechanics Affects Your Life
While you might not think about quantum mechanics being part of your everyday life, it turns out that it might play a role in some of the most familiar things, from the sunlight in the trees to the nose on your face!

Sharknado Reloaded: Yep, Still Impossible
SciShow revisits Sharknado to discover the truth behind who would win in a battle between a tornado and a bomb. The answer... won't actually surprise you. But you might learn some interesting science along the way!

Will the Moon Ever Leave the Earth's Orbit?
Every year the moon’s orbit gets a little bigger and it moves just a little farther away. Should we worry about the Moon breaking free?

Why Scientists Want to Build a Shoebox-Sized Particle Accelerator
If you want to make particles move really fast, you have to build a particle accelerator that is really big, right? Not anymore! Hosted by: Hank Green

3 Freaky Things Explained: Bug Sex, Polar Vortex and Chain Fountain!
Hank shares the latest developments in science, this week demystifying three freaky things in nature: the polar vortex, why some bugs are infertile, and how a chain can appear to defy gravity. You're welcome!

Why Do the Planets Orbit in the Same Plane?
While there is a little wiggle room, the planets in our solar system really are orbiting on mostly the same level. Why do they do that?

Why Do Golf Balls Have Dimples?
The size, shape, and designs of the balls used in sports are usually the results of decades or even centuries of trial and error, and the cute, dimply li'l golf ball is no different!

TED-Ed: The battle that formed the universe | Fabio Pacucci
It's time for the biggest battle in the Universe: the Big Bang. In one corner is gravity— the force that brings all matter together. In the other is pressure— the force that can push matter away. Over the next several hundred thousand...

TED-Ed: How do airplanes stay in the air? | Raymond Adkins
By 1917, Albert Einstein had explained the relationship between space and time. But, that year, he designed a flawed airplane wing. His attempt was based on an incomplete theory of how flight works. Indeed, insufficient and inaccurate...

The more general uncertainty principle, beyond quantum
The general uncertainty principle, about the concentration of a wave vs the concentration of its fourier transform, applied to two non-quantum examples before showing what it means for the Heisenberg uncertainty principle.

Some light quantum mechanics (with MinutePhysics)
An introduction to the quantum behavior of light, specifically the polarization of light. The emphasis is on how many ideas that seem "quantumly weird" are actually just wave mechanics, applicable in a lot of classical physics.

Systems and Objects
In this video Paul Andersen explains the differences between a system and an object. Depending on the scale it often times easies to view a system as an object if the constituent parts aren't relevant to the question being asked. He also...

Feynman's Infinite Quantum Paths
There is a fundamental limit to the knowability of the universe. The Heisenberg uncertainty principle tells us that the more precisely we try to define one property, the less definable is its counterpart. Knowing a particle's location...

The Unreasonable Efficiency of Black Holes
This video is about how efficient various reactions are at converting mass to energy (as we know from the Einstein mass-energy equivalence of E=mc^2). Antimatter is very efficient but it is not naturally-occurring. Chemical reactions...
