Making a Realistic Simulation of the Sun
We’ve created simulations to recreate the difference in time it takes for the Sun’s equator and poles to complete rotations, and the way we’ve solved is a bit surprising. And it looks like the Milky Way may not be great at mixing metals,...

Meselson-Stahl Experiment
Paul Andersen explains how the Meselson-Stahl experiment was used to prove that DNA copied itself through a semi-conservative process. They grew E. coli in a medium containing heavy nitrogen (N-15). They then added the E. coli to a...

Wave Speed
In this video Paul Andersen explains how the wave speed measure the speed of a wave through a medium. The medium determines the speed of the wave. The velocity of the wave is equal to the product of the wavelength and the frequency of...

Are We Living in an Ancestor Simulation? ft. Neil deGrasse T
The idea that our reality is a simulation is not as far-fetched as you may think. Many philosophers, scientists and tech-billionaires are seriously considering not just the possibility but the high probability that our civilization may...

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...

Controlled Experiments - Crash Course Statistics
We may be living IN a simulation (according to Elon Musk and many others), but that doesn't mean we don't need to perform simulations ourselves. Today, we're going to talk about good experimental design and how we can create controlled...

Conservation of Electric Charge
In this video Paul Andersen explains how the conservation of charge applies to objects in a system. When a charged object induces charge or conducts charge to a neutral object the net total of charge will not change. Grounding allows...

Wave Period and Frequency
In this video Paul Andersen explains how the period is the time between wave and the frequency is the number of waves per second. Period is measured in seconds and frequency is measured in Hertz. Wave period and wave frequency are...

Electric Field Strength
In this video Paul Andersen explains how the electric field strength is directly related to the amount of charge that generates the field.

Traveling Waves
In this video Paul Andersen explains how traveling waves move through space and time. The reflection and interference of traveling waves can create standing waves which appear motionless. Examples of traveling waves in one and two...

Operon
In this video Paul Andersen describes the elements of an operon. The promoter allows the RNA polymerase to transcribe the required genes. The operator and repressor regulate the expression of the genes by blocking the RNA polymerase. The...

Half-Life and Radioactive Decay
In this video Paul Andersen explains how a radioactive nuclei can decay by releasing an alpha, beta, or gamma particle. The exact moment of decay for each nuclei can not be determined but probability is useful in predicting the...
