again, i will talk about track, doc. there was one thing which i noticed during a track meet. while i was watching one race, i reconfirmed myself that the speed of light is faster than the speed of sound. i was on the other side of the track when the official made a gun shot into the sky. i saw smoke coming out of his gun but i heard no sound until maybe like .3-.5 second later. it was pretty cool, i must say because when i was near the official, the smoke coming out and the sound go off at pretty much the same time. this is probably the reason why the hand time and electronic time for state qualifying time is different. because the timer is some distance away from the starting line, they would have a lag when they start their clock. it probably involves human reaction time and whatnots but whatevers. whereas, when it is done electronically, then there would be almost no lag since there is no human error involved (yay to the technologies).
