TED-ED: Why is glass transparent? - Mark Miodownik
If you look through your glasses, binoculars or a window, you see the world on the other side. How is it that something so solid can be so invisible? Mark Miodownik melts the scientific secret behind amorphous solids.

MAGNETS: How Do They Work?
ow do magnets work? Why do they attract and repel at long distances? Is it magic? No... it's quantum mechanics, and a bit more, as we explain in this, the longest MinutePhysics video ever.

Stimulated Emission
In this video Paul Andersen explains how stimulated emission can be used to create coherent light. When an atom absorbs a photon it moves to a higher energy level through stimulated absorption. It may then release a photon and moves to a...

Chemical Analysis
In this video Paul Andersen explains how chemical analysis is important in determining the composition, purity and empirical formula of a compound. An empirical formula determination problem is also included.

Oxygen is Killing You
Hank introduces us to oxygen - the element that makes it possible for most animals to live, but which is simultaneously responsible for a lot of bad things going on in our bodies.

TED-Ed: Just how small is an atom? - Jonathan Bergmann
Just 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...

The Quantum Theory that Connects the Entire Universe
Quantum mechanics is weird and seems a bit...complicated. But understanding it can help us to understand the universe.

The Electron: Crash Course Chemistry
Hank brings us the story of the electron and describes how reality is a kind of music, discussing electron shells and orbitals, electron configurations, ionization and electron affinities, and how all these things can be understood via...

Atomic Nucleus
In this video Paul Andersen explains how the structure of the nucleus influences the properties of the atom. The number of the protons determines the kind of element. Isotopes are formed when the number of protons remain the same but the...

How to Stop Light in Its Tracks
Scientists have created beams of light that are slower than a car! Not only that, but with the literal flick of a switch, they can freeze that beam of light in place!

Is the Size of Neutron Stars A Lie, Or Only A FRIB?
Have we been wrong about how big neutron stars are this whole time?

Conservation of Nucleon Number
In this video Paul Andersen explains how the nucleon number and charge is conserved in all nuclear reactions and radioactive decay. Fission, fusion, alpha decay, beta decay, and gamma decay all conserve the number of neutrons and...

Oklo, the Two Billion Year Old Nuclear Reactor
SciShow takes you to a uranium deposit in Africa where, eons ago, a unique set of conditions came together to form the world's only known natural nuclear reactor. Check it out! No radiation suit required!

Quantum Mechanics - Part 2: Crash Course Physics
e=mc2... it's a big deal, right? But why? And what about this grumpy cat in a box and probability? In this episode of Crash Course Physics, Shini attempts to explain a little more on the topic of Quantum Mechanics.

These Stars Are Being Eaten Alive from the Inside
In general, a star’s size will determine its final destiny. Some stars fizzle out, while others explode, and what seals their fate may come down to a curious, cannibalistic process happening inside their cores!

Why Do Atoms Bond?
SciShow explains what makes atoms bond (and what makes them sometimes seem promiscuous).

The Manhattan Project
Some of the greatest advances in science have come from humanity's more destructive impulses. This is not the fault of science - when we discover powerful truths about the universe it's up to us to decide how to use them because they can...

2012 Nobel Prize - How Do We See Light
What was the 2012 Nobel Prize in physics given for? Capturing a single photon of light!

The Search for Antimatter
If you don't have any idea what antimatter is, you don't have to feel bad - the brightest minds in the world have only recently begun to understand what it is and how it works. Hank gives us the run down on what we know about antimatter,...

Antimatter Light Spectrum Discovered!
Scientists were able to measure the emission lines of antimatter! And we may have some new clues about how dinosaurs lost their teeth on the way to becoming birds.

Redox Reactions: Crash Course Chemistry
All the magic that we know is in the transfer of electrons. Reduction (gaining electrons) and oxidation (the loss of electrons) combine to form Redox chemistry, which contains the majority of chemical reactions. As electrons jump from...

TED-Ed: What is the coldest thing in the world? - Lina Marieth Hoyos
The coldest materials in the world aren't in Antarctica or at the top of Mount Everest. They're in physics labs: clouds of gases held just fractions of a degree above absolute zero. Lina Marieth Hoyos explains how temperatures this low...

Nuclear Physics: Crash Course Physics
It's time for our second to final Physics episode. So, let's talk Einstein and Nuclear Physics. What does E=MC2 actually mean? Why is it so useful to us as physicists and humans? In this episode of Crash Course Physics, Shini sits down...
