Random walk can teach you plenty

Of particular interest is just before the 11 minute mark. The random motion of molecules describes the temperature of molecules. The temperature is the random motion of molecules, which averages out to what we call temperature. The motion is KINETIC in nature. That means it moves. But it wasn't about physics. It was about making money.

And I thought I could predict the prices of stocks. The random walk theory says how wrong I was. Or was I? I lost plenty of money on such a silly thought. Or was it silly, according to this video? Mind bending, but if I had solved it, maybe I would be rich right now.
