I Made A Solenoid Engine!

I built a solenoid engine. Unlike most motors out there that hide how they work, this beauty bears all. A solenoid is a kind of electromagnet. When electricity flows through this coil, a magnetic field pulls the magnet-topped piston inside up. But when the piston reaches the top, a cam on the axle it’s turning cuts off the flow of electricity, and the flywheel's momentum pulls the piston back down.

But once down, the cam disengages, electrical flow resumes, and the piston goes up again. You can see how it turns electrical energy into rotational energy. To make this happen, my team and I got to design a bunch of custom cross axle compatible parts that I had been wanting for a long time: special cams, pistons, arms, wires, a heavy brass flywheel, and of course, the solenoids themselves.

We even made elliptical gears, Nautilus gears, and a Geneva mechanism. If you’d like to build one yourself and add these parts to your arsenal—too bad, so sad, psych! You can buy one! ABS plastic, ooh, and look at those colors! The first 500 people to use code "I love you Michael" will get 10% off.

Relation of null space to linear independence of columns

So I have the matrix A over here, and A has M rows and N columns. So we could call this an M by N matrix. What I want to do in this video is relate the linear independence or linear dependence of the column vectors of A to the null space of A. First of a…

The Banach–Tarski Paradox

Hey, Vsauce. Michael here. There’s a famous way to seemingly create chocolate out of nothing. Maybe you’ve seen it before. This chocolate bar is 4 squares by 8 squares, but if you cut it like this and then like this and finally like this, you can rearrang…

Externalities: Calculating the Hidden Costs of Products

What’s a mispriced externality you mentioned at some point during our podcast? An externality is when there is an additional cost that is imposed by whatever product is being produced or consumed that is not accounted for in the price of the product. Some…

Metallic bonds | Molecular and ionic compound structure and properties | AP Chemistry | Khan Academy

Now the last type of bond I’m going to talk about is known as the metallic bond, which I think I know a little bit about because I was the lead singer of a metallic bond in high school. I’ll talk about that in future videos, but let’s just take one of our…
