Introduction to how cell cycle control is lost in cancers.
This art history video discussion examines Ludwig Mies van der Rohe's "Seagram Building", 375 Park Avenue, New York City (1958). Note: In the video I call Le Corbusier a French architect. This is somewhat reductionist since he was born in Swizerland and became a French citizen in 1930.
See how a wire carrying a current creates a magnetic field. Created by Sal Khan.
Sal shows how to determine the magnetic force between two currents going in opposite directions. Created by Sal Khan.
Sal shows how to determine the magnetic force between two currents going in the same direction. Created by Sal Khan.
Sal shows how to find the size and direction of the magnetic force using F=qvB and the right hand rule. Created by Sal Khan.
Sal derives the formula F=ILB to determine the force on a current carrying wire. Created by Sal Khan.
Sal does an example problem to determine the size and direction of the magnetic force on a proton moving through a magnetic field. Created by Sal Khan.
Sal determines the radius of the circle traveled by the proton in the previous example by using the formula for centripetal acceleration. Created by Sal Khan.
In this video David explains how to find the magnitude of the electric field created by a point charge and solves a few examples problems to find the electric field from point charges. Created by David SantoPietro.
Overview of minor vs. major beats.
Pamela shows how to program animations, using the draw() function.
We'll explain how to draw circles with code (JavaScript and ProcessingJS), and then you'll get to try it yourself in a challenge.

Nuclear binding energy is the energy required to split an atom’s nucleus into protons and neutrons. Mass defect is the difference between the predicted mass and the actual mass of an atom's nucleus. The binding energy of a system can appear as extra mass, which accounts for this difference. Created by Jay.
How we approach master lighting.
The role that math plays in computer animation.
The Maxwell-Boltzmann distribution describes the distribution of speeds among the particles in a sample of gas at a given temperature. The distribution is often represented graphically, with particle speed on the x-axis and relative number of particles on the y-axis. Created by Sal Khan.
How can we quantify/measure an information source? Created by Brit Cruise.
