How to Make an Electron Gun

If you understand this slide, you will understand quantum theory. Usually when you hit a golf ball, it obeys the laws of physics,. We're dealing with what we would call real objects. Let's do the same thing with water. As the water wave hits the barrier with two slits, it diffracts and those waves start to interfere with each other. If you throw two pebbles in a pond, you'll get the same effect. Now let's try electrons. I personally can't make an electron gun, but I am reliably informed that humanity is quite capable of making an electron gun. In fact, a television, an old television was an electron gun - just like
