Introduction to shot lighting.
Sieve of Eratosthenes allows us to generate a list of primes. Created by Brit Cruise.
The sign convention for passive components defines what we mean by positive and negative voltage and current. Created by Willy McAllister.
A systematic approach to simplify a complicated resistor network by looking for series and parallel resistor patterns. Created by Willy McAllister.
Species number and relative abundance affect the diversity of a community. We can use Simpson's index of diversity to quantify and compare the diversity of different communities.
How can we model water using particles?
Sine and cosine can be generated by projecting the tip of a vector onto the y-axis and x-axis as the vector rotates about the origin. Created by Willy McAllister.
If we introduce time as the argument to the sine function, we get a sine wave. Animated. Created by Willy McAllister.
What happens when there's only one hole? Created by David SantoPietro.
In this video we will explore the structure and function of the human skeleton in depth, as well as some animal skeletons. Created by Tracy Kim Kovach.
Voltages and currents often have an exponential shape. We look at some properties of exponential curves and learn how to rapidly sketch accurate waveforms. Created by Willy McAllister.
Sketch exponentials with different time constants. Created by Willy McAllister.
To make realistic water we'll need to soften the particle collisions.
Snell's Law Example 1. Created by Sal Khan.
Snell's Law Example 2. Created by Sal Khan.
How the the sodium-potassium (Na+/K+) pump works. Its role in establishing resting membrane potentials. Created by Sal Khan.
Understanding solar eclipses and lunar eclipses. Why don't we have a solar eclipse every new moon (every time the Moon is between the Earth and Sun)? Why don't we have a lunar eclipse every time the Earth is between the Sun and Moon.
Basics of soldering safety. Created by Karl Wendt.
How to find the amplitude, period, frequency, and wavelength for a sound wave. Created by David SantoPietro.
