Last night at dinner we were treated to a very lengthy (albeit one-sided) conversation about Nikola Tesla who was a Serbian-American inventor, electrical engineer, mechanical engineer, physicist, and futurist best known for his contributions to the design of the modern alternating current (AC) electrical supply system.
This morning, when I thought I was catching Graham during a moment of daydreaming, he told me he was actually just pondering what he had just learned in his Sound and Light science book. He taught us that if you were to place a needle on the nose of a jet, it would not emit a sonic boom when breaking the sound barrier. Furthermore, you would not be able to control the plane. Later today, we were lazing on the beach, I on my towel and he in his sand throne and I declared that the clouds weren’t moving. He corrected me that, in fact, they were. Then I asked him how fast the earth was moving. He queried, “Do you want to know how fast it is spinning on its axis or how fast it is orbiting the sun?” Silly me, “What’s the difference?” This was followed by a lengthy recitation of facts and blah, blah, blah ending with the exact numerical values of both answers. I came home and looked it up.
I guess he is learning something after all.
