What Happens Inside a Proton?
If we ever want to simulate a universe, we should probably learn to simulate even a single atomic nucleus. But it’s taken some of the most incredible ingenuity of the past half-century to figure out how that out. All so that today I can...

Meet CERN's New Particle: A Double-Charm Baryon!
This week, CERN announced a new particle that will help further understanding of the fundamental forces, and a simulation of ancient creatures may give us a clue as to how life grew beyond the microscopic.

Why Protons Are Still Such a Mystery to Scientists
Protons make up most of the regular matter int he universe, but we're still figuring out a few of their quirks... Or quarks. Join Hank Green and learn why protons are still so mysterious to scientists, and what we've discovered about...

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...

The Quest for Glueballs
The quantum world is weird. Today we're looking at a strange particle called a glueball that contains no matter...they're made of pure force!

The Universe As We Know It Shouldn't Exist | The Matter-Antimatter Problem
The universe is a pretty grand place to live, but scientists have one issue with it, it's an anomaly that should be scientifically impossible.

Extreme Hypothetical Stars
You might think we've already found every kind of star by now, but astronomers think there are more that should hypothetically exist!

TED-Ed: What’s the smallest thing in the universe? - Jonathan Butterworth
If you were to take a coffee cup, and break it in half, then in half again, and keep carrying on, where would you end up? Could you keep on going forever? Or would you eventually find a set of indivisible building blocks out of which...

Strange Stars
What happens when matter can't get any denser yet somehow does? The answer - it becomes strange. Strange Stars may be the most massive stellar remnant that is just shy of forming a black hole. And they could be even cooler than black holes.
Crash Course
A Brief History of the Universe
Thanks to the wonders of physics, astronomers can map a timeline of the universe’s history. Today, Phil’s going to give you an overview of those first few minutes (yes, MINUTES) of the universe’s life. It started with a Big Bang, when...

Why Do People Say We've Reached the End of Physics?
Our fundamental picture of the universe seems pretty nearly complete these days, to the point that some people are suggesting that we’ve arrived at some version of “the end of physics.” And sure, physics is at a turning point, but it...

TED-Ed: The beginning of the universe, for beginners - Tom Whyntie
How 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...

This Tank of Water Could Change Physics Forever
No one has ever conclusively seen a proton turn into other, lighter particles, but fifty million liters of water in Japan might change that and our ideas about subatomic particles forever.

Strong Interaction: The Four Fundamental Forces of Physics #1b
Hank continues his primer on the strongest of the four fundamental interactions of physics, the strong interaction. Today he talks about the nuclear force and a force carrier called a pion.
SciShow
Weak Interaction The Four Fundamental Forces of Physics #2
Hank continues our series on the four fundamental forces of physics by describing the weak interaction, which operates at an infinitesimally small scale to cause particle decay.

Strong Interaction: The Four Fundamental Forces of Physics #1a
Part one of a four part series on the fundamental forces (or interactions) of physics begins with the strong force or strong interaction - which on the small scale holds quarks together to form protons, neutrons and other hadron particles.

Elementary Charge
In this video Paul Andersen explains how electric charge is quantized and how the smallest unit of charge is 1.6x10^-19 C, or the elementary charge. Robert Millikan discovered the elementary charge using the oil drop experiment....

Strong Nuclear Force
In this video Paul Andersen explains how the strong nuclear force holds the nucleus together in spite of repulsive electrostatic charges acting on the nucleons. Mesons exchanged between nucleons keep the nucleus intact and gluons...

How Quarks Fixed the Mess That Was Particle Physics
Particle physics isn't simple, but it was much more confusing before physicists knew about quarks.

Fundamental Particles
In this video Paul Andersen explains how at the smallest level all matter is made of fundamental particles; including quarks, electron, photons and neutrinos. He explains how understanding the properties of these particles allows us to...
