The 17+ Different Kinds of Ice!
Ice is ice, right? Wrong! From the vacuum of deep space to the inside of ice giant planets, ice gets stretched and squished into way more forms than what we find here on Earth.

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...

Intermolecular Potential Energy
In this video Paul Andersen explains the importance of intermolecular forces in chemistry. Intermolecular forces exist between dipoles (like hydrogen bonds), between dipoles and induced dipoles (like Ar and HCl) and between induced...

Coupled Reactions
Paul Andersen explains the importance role of coupled reactions in biology. He starts by explaining how the power of a river can be harnessed by a water mill to grind grains. He describes the importance of ATP and how it is used within...

TED-ED: Electric vocabulary - James Sheils
We all know the words around electricity -- _charge," _positive," _battery" and more. But where do they come from and what do they really mean? Let the history of these words illuminate the physics of electric phenomena.

Are the Fundamental Constants Changing?
The laws of physics are the same everywhere in the universe. At least we astrophysicists hope so. After all, it's hard to unravel the complexities of distant parts of the universe if we don't know the basic rules. But what if this is...

How To Make MUONS
This video is about how to create muons in a particle accelerator via bombardment of heavy nuclei with protons, which results in creation of charged pions (plus and minus). The pions then decay into muons and mu neutrinos, and the muons...

The Higgs Mechanism Explained
Quantum Field Theory is generally accepted as an accurate description of the subatomic universe. However until recently this theory had one giant hole in it. The particles it describes had no mass!

TED-ED: What is the shape of a molecule? - George Zaidan and Charles Morton
A molecule is nearly all empty space, apart from the extremely dense nuclei of its atoms and the clouds of electrons that bond them together. When that molecule forms, it arranges itself to maximize attraction of opposite charges and...
