More Talks with K

I was talking to "K" at work again today. I was curious about something so I said, "K, do you know how a magnetron works?" He started to sketch one out on my white board, but paused and said, "First I need to teach you something about the theory of antenna design." So I got two for the price of one. K told me he learned about the design of a magnetron from an encyclopedia when he was growing up.

As an FYI, a magnetron is a very clever invention that makes your microwave oven possible. It's also used in radar.
