My six year old daughter looked at me and asked, "What's a meschatic?"
I explained, "A schematic is a drawing of an electrical circuit. It tells people how to make it so that electricity goes the way we want and does what we want it to do."
I pointed at the light above us. "This light is an electric circuit. So is the computer. Some circuits are simple like this light and some are complex like the computer. I make complex ones that go in missiles."
She looked at me with wonder in her eyes. "You draw all day at work!?"
Yes. Yes I do.
