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...

AP Biology Practice 5 - Analyze Data and Evaluate Evidence
In this video Paul Andersen explains how scientists analyze data and evaluate evidence. He starts with a description of data and how it must be properly displayed. He then describes types of data in each of the four big ideas. He finally...

Anti-Matter and Quantum Relativity
Paul Dirac's insights into the nature of Quantum Mechanics laid the foundation for Quantum Field Theory and predicted the existence of anti-matter. Part 1 in our series on Quantum Field Theory.

The Black Hole Tipping Point
This video is about the Schwarzschild radius of a black hole, (its "event horizon"), and how much mass and density is required to reach the point of no return where an object like a star, neutron star, red giant, etc will collapse into a...

The Phantom Singularity
Isaac Newton's Universal Law of Gravitation tells us that there is a singularity to be found within a black hole, but scientists and mathematicians have found a number of issues with Newton's equations. They don't always accurately...

The One-Electron Universe
Could it be that all the electrons in the universe are simply one, single electron moving back and forth through time?

Force-Time Graph
In this video Paul Andersen explains hot the force-time graph can be used to determine the impulse of an object. Since the impulse and the change in momentum are equivalent the graph can also be used to determine the change in momentum...

Mass and Energy
In this video Paul Andersen explains how mass can be converted to energy and energy can be converted to mass. The equation E=mc2 can be used to determine the amount of energy released from nuclear processes.

How to Build a Blackhole
Black holes have mystified physicists for decades, but with the help of quantum mechanics, we are beginning to make serious progress in understanding these strange objects. This week on Space Time, Matt dives deeper into the physical...

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!
Crash Course Kids
Bowled Over
So, variables. There are lots of them when trying to test an idea. The trick is to isolate one variable at a time to get reliable results every time. But, how do we do that? In this episode of Crash Course Kids, Sabrina shows us how to...

TED-Ed: Why do buildings fall in earthquakes? - Vicki V. May
Earthquakes have always been a terrifying phenomenon, and they've become more deadly as our cities have grown - with collapsing buildings posing one of the largest risks. But why do buildings collapse in an earthquake? And how can it be...

5 Baffling Mysteries About the Universe
At the beginning of the 20th century, many scientists thought that we had learned all there was to know about physics. The problem is, the better we get at measuring things and building models of our universe, the more we discover that...

Inertial Mass
In this video Paul Andersen explains how inertial mass is defined and measured. When a force is applied to an object or a system it will accelerate. Using Newton's Second Law of Motion (F=ma) you can calculate the inertial mass.
