The gun WAS off to the side. now it makes a sound directly behind each runner.

it was the light I was referring to. -- nm - Andie Aug 3, 13:21 1
- yeah, no idea. -- nm - loosilu Aug 3, 13:27
Yes, but the light being emitted from the gun is still only coming from the side, and since light is roughly 88,000 times faster than sound it gets there first. - Ender Aug 3, 13:21 11

    - they clearly have to make the lanes farthest from the gun, a couple of nanometres shorter -- nm - zork Aug 3, 13:37 1
      - Hmm, if they run north-to-south that might be accommodated by increased expansion due to the western lanes having been exposed to the sun slightly longer... -- nm - Ender Aug 3, 13:42
    - Are we also accounting for the Corilolis Effect? - Reagen Aug 3, 13:25 6
      - The 100m track runs north/south so they'd all be affected equally. -- nm - Ender Aug 3, 13:27 5
        
        but they're all on slightly different latitude lines. -- nm - Reagen Aug 3, 13:29 4
        
        (throughout the race) -- nm - Reagen Aug 3, 13:30 3
        
        Well, that's their own fault for not running faster. They all start at the same spot (within a few mm at least). -- nm - Ender Aug 3, 13:32 2
        
        this was the point I was about to make. the start and finish lines are not *exactly* 100m nor exactly parallel. - zork Aug 3, 13:35 1
        
        do left handed athletes have an advantage in the southern hemisphere? -- nm - zeitgeist Aug 3, 13:58
