I so loved learning about rockets and getting into space that I continued to delve into physics in the form of a series of lectures by Professor Steven Pollack called Great Ideas of Classical Physics. Amazing stuff! He's good enough to avoid a lot of the mathematics and still give a loser like me a great sense of what it's all about. He recommended trying to figure out how one would figure out the circumference of the globe without today's modern technology. The dog and I tried, but we only got as far as the sun and something to do with shadows before we resorted to the Interweb where we learned all about Eratosthenes and his extraordinary skill and perceptiveness!
