Happy Christmas to all
I am presently trying to create a repertoire with CD's as backing music because George Pollacco is rather reluctant to play frequent gigs. I on the other hand, want to play as much as possible...firstly because I need the money and secondly because I need to keep in touch with the music scene and, I have to admit it, I love the attention.
Well, hope for the best. Cya.
Puzzle of the day from perplexus.info:Relativistic snapshot (Difficulty: 3 of 5)  The Theory of Relativity is not required to solve this problem. The Lightway Express boasts half the speed of light. According to the advertisements, this relativistic speed literally shortens long trips. This is true. At one point, the train goes through a tunnel of about 111.8 km, but from the train's point of view, it is exactly 100 km long. As a curious tourist, I resolved to experience relativistic speeds, and furthermore, bring home memories in photo form. So while I was riding the Lightway Express, I pointed my camera out a window, and took a picture of the entire 100 km tunnel. Later, when I examined my excellently timed photo, I was disappointed to find that the picture showed a tunnel that was much longer than 100 km.
How long is the tunnel in my photo, and why is it longer than I expected? Was I looking out the front or the back window of the train? |
