Challenge question: if 1kg of apples is $5 and 2kg is $10, how much is -1kg of apples? The answer? Priceless. Because you could use negative-mass apples to build warp drives, travel in time, and construct a perpetual motion machine. In...

If you used every particle in the observable universe to do a full quantum simulation, how big would that simulation be? At best a large molecule. That’s how insanely information dense the quantum wavefunction really is. And yet we...

Energy is the most powerful and useful concept in all of physics, but what exactly is it?

Did you know the center of mass can be outside the object itself? Learn what center of mass really means and see clear examples with everyday objects like bananas, donuts, and golf clubs.

This video explains Quantum Mechanics intuitively. Classical mechanics failed to describe how an electron could orbit an atom. An accelerating charge always creates electromagnetic radiation. This means it...

Summary:

By the end of 1905, we had two big new equations in physics. Max Planck’s, Energy equals Planck’s constant times the frequency, and Einstein’s Energy equals the mass times the speed of light squared. A...

Physics is the grandaddy of the sciences! When those ancient dudes in togas were philosophizing about the way the universe works, they were setting the stage for what we now know of as physics, even though it didn't really get going...

Kinetic Molecular Theory & Ideal Gas Law Derivation

Defining the Force of Gravity or Weight and Gravitational Mass. We also determine the dimensions for force in both Metric and English units.
