Torque: Crash Course Physics #12

Torque: Crash Course Physics #12

You have a box. A ring. And a marble. And they’re all at the top of a ramp. Because you know how physics loves ramps. Especially hypothetical ramps! So, let’s say this ramp would allow for static friction, but not kinetic friction. Now, you let go of all of these objects at the same time, […]

Electric Fields: Crash Course Physics #26

Electric Fields: Crash Course Physics #26

Last time, we talked about how charged particles exert electrostatic forces on one another. We calculated these forces using the charge of each particle: which can be either positive or negative, and the distance between them, and we did it with the help of Coulomb’s Law: the equation that tells us the force generated by […]

Silicon – The Internet’s Favorite Element: Crash Course Chemistry #35

Silicon – The Internet’s Favorite Element: Crash Course Chemistry #35

If they know it at all, most people know silicon from the valley in California that bares its name. The birthplace of modern computing where technological dreams became reality. Where brilliant twenty-somethings became millionaires. But we chemists know silicon first and foremost as the most abundant element in the earth’s crust. Oxides of silicon, known […]

The Industrial Revolution: Crash Course History of Science #21

The Industrial Revolution: Crash Course History of Science #21

You probably know some of the signs of industrialization in the nineteenth century: Trains connected cities, symbolizing progress. But they also brought about the destruction of rural lands, divisions between social classes, and rapid urbanization. Clocks, meanwhile, became technologies of standardization: They created a universal time, as opposed to a local “sun time.” But clocks […]

Electric Charge: Crash Course Physics #25

Electric Charge: Crash Course Physics #25

The shock you get from a doorknob. That trick you used to do with a balloon, to make your hair stick up. Or, of course, a lightning strike. They’re all governed by the same principle: static electricity. Static electricity occurs when an object obtains a net amount of positive or negative electric charge, creating an […]

Operating Systems: Crash Course Computer Science #18

This episode is supported by Hover. Hi, I’m Carrie Anne, and welcome to Crash Course Computer Science! Computers in the 1940s and early 50s ran one program at a time. A programmer would write one at their desk, for example, on punch cards. Then, they’d carry it to a room containing a room-sized computer, and […]
