the mind of a young engineer

I didn’t get a chance to tell you about a conversation that I had with Beren on Saturday. He told me that Auntie had said that Rick goes sky diving. Then he asked, “What’s sky diving?”
I told him that it’s when a person wears a parachute and jumps from an airplane and floats down to the ground.
Then he said, “A person couldn’t sky dive on the moon because they wouldn’t float down because there’s no gravity and there’s no air on the moon.”
I said, “That’s right, you have to use a rocket to get to the moon.”
His next question was, “Why isn’t there air on the moon?”I explained Earth’s atmosphere by comparing it to the white around an egg yolk, and the moon being outside the egg. Then the conversation went a different direction.
