Rubbish, in the old days they had to throw a knotted rope out the window to measure the speed. Sheeesh, man. 1 Link to comment Share on other sites More sharing options...

Sheeesh, man. I put this to you, and all the other budding scientist members on TVFourm. If you were to connect a string from exactly the north pole of about 1 km long and tie the other end to a man (or a lady). Then get them to bunny-hop* in a big circle until they get back to the starting point. Do the same in the opposite way - being careful to do the bunny-hops exactly the same - back to the starting point. Make a careful recording of the times. Just so to eliminate human error, the task should be repeated 100 times. We would find a consistent difference in the two times. * Must be bunny-hops, or little jumps, not walking or running.
