The first time I realized I loved physics, and not just astronomy, was in a class in high school. The teacher was a ball – he taught photography, as well as physics, and had a bowling ball hanging from a chain over the counter in the front of the class. He would have a student sit up on the counter and bring the ball up to their nose and let it go – a living example of pendulum theory, but of course we all thought there’d be a bloody nose involved. There wasn’t, of course, and I was hooked.
Then he explained that a heat coil on the back of a refrigerator is how the fridge stays cold, and I thought, this isn’t physics, it’s magic!
“Any sufficiently advanced technology is indistinguishable from magic.”
