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...

The Star That Trolled Astronomers
In 1967, a star was discovered that seemed to be different than most stars, . . . it looked like it was blinking.

Torque: Crash Course Physics
What is torque? This is one of those things that you may have heard about in passing but never really understood. In this episode of Crash Course Physics, Shini sits down with us to discuss what torque is, how it works, why it works, and...

The Law of Conservation: Crash Course Engineering #7
Today Shini explains the law of conservation, beginning with simple, steady-state systems. We’ll discuss conversion and yield, accumulation, and how generation and consumption can affect how much accumulation there is in a system.

Newton's Second Law
In this video Paul Andersen explains how Newton's Second Law applies when a net force acts on a body. The net force vector and the acceleration vector will act in the same direction. If an object acts on another object in a system the...

The Supernova of 1054, Our Very Special Guest Star
All of humanity likely saw it, a brilliant supernova that lit up the daytime sky in 1054. But 960 years later, there’s still a lot we dont quite understand about the famous celestial phenomenon.

TED-ED: The 2,400-year search for the atom - Theresa Doud
How do we know what matter is made of? The quest for the atom has been a long one, beginning 2,400 years ago with the work of a Greek philosopher and later continued by a Quaker and a few Nobel Prize-winning scientists. Theresa Doud...

Passing Gases: Effusion, Diffusion and the Velocity of a Gas - Crash Course Chemistry
We have learned over the past few weeks that gases have real-life constraints on how they move here in the non-ideal world. As with most things in chemistry (and also in life) how a gas moves is more complex than it at first appears. In...

Sun VS. Atomic Bomb
Hank puts the immense power of the sun into perspective through comparison with the most powerful nuclear bomb ever detonated.

Chemical Change
In this video Paul Andersen explains how chemical differs from physical change. In the laboratory macroscopic observations are used to infer changes at the particulate level. Evidence for chemical change include gas production, change in...

Unit Conversion & Significant Figures: Crash Course Chemistry
A unit is the frequently arbitrary designation we have given to something to convey a definite magnitude of a physical quantity and every quantity can be expressed in terms of the seven base units that are contained in the international...

Low Mass Stars
Today we are talking about the life -- and death -- of stars. Low mass stars live a long time, fusing all their hydrogen into helium over a trillion years. More massive stars like the Sun live shorter lives. They fuse hydrogen into...
