Temperature
In this video Paul Andersen explains how the temperature is a measure of the average kinetic energy of particles in an object. The temperature is proportional to the average kinetic energy according to the Kelvin scale. At absolute zero...

How to Make a Hologram
Augmented reality isn’t just science fiction anymore! In this episode, Michael becomes a hologram and Hank explains how one set of new technologies made it happen.

Equilibrium
In this video Paul Andersen explains how equilibrium is achieved in a reversible reaction. When the rate of the forward reaction is equal to the rate of the reverse reaction the system is at equilibrium. Graphical analysis of equilibrium...

Why Does Coffee Make You Poop?
It's common knowledge: you drink a lot of coffee, you're definitely going to poop. What isn't common knowledge is why your body reacts that way

Motion
In this video Paul Andersen describes motion as the movement of an object over time. Displacement, velocity and acceleration are all defined. An experiment in motion is used to calculate velocity and acceleration of a tennis ball.

Einstein and The Special Theory of Relativity
How Einstein (& others) discovered Special Relativity. Pi day (3.14) is Albert Einstein's Birthday! To celebrate, we'll explain 4 of his most groundbreaking papers from 1905, when he was just 26 years old.

Gases
In this video Paul Andersen explains how gases differ from the other phases of matter. An ideal gas is a model that allows scientists to predict the movement of gas under varying pressure, temperature and volume. A description of both...

Uniform Circular Motion: Crash Course Physics
Did you know that centrifugal force isn't really a thing? I mean, it's a thing, it's just not real. In fact, physicists call it a "Fictitious Force." Mind blown yet? To explore this idea further, this week Shini sits down with us to...

Magnetic Field of a Wire
In this video Paul Andersen explains how current moving through a wire will generate a magnetic field tangent to the wire. As the current increases the magnetic field will increase and as the radius from the wire increase the magnitude...

Measuring the Magnetic Force
In this video Paul Andersen explains how a magnetic force arises when magnets or moving electric charges interact with one another. A magnetic dipole will orient towards a magnetic field. When an electric charge is moving it will...

Diffraction Effects
In this video Paul Andersen explains how diffraction can be affected by the size of the wavelength. When waves pass through an opening or move around an obstacle a shadow region is created. The size of the shadow zone will decrease as...

Wave Diffraction
In this video Paul Andersen explains how waves will diffract (or bend) around an obstacle or while traveling through and opening. Diffraction will be maximized when the size of the opening or obstacle matches the wavelength.

Magnetic Force
In this video Paul Andersen explains how a charge particle will experience a magnetic force when it is moving through a magnetic field. The right-hand rule is described as a method for determining the direction of the force. The...

Refraction of Light
In this video Paul Andersen explains how light can be refracted, or bent, as it moves from one medium to another. The amount of refraction is determined by the angle of incidence and the index of refraction. Snell's Law can be used to...
