I’m trying to find good online sources which explain how the various events are judged, and/or explain the technology which enables results to be measured down to fractions of a second, or of a centimentre, so quickly.
Re judging - so I watch two of those amazing, incredible gymnasts do things that it seems no human body should be able to do. One gets 9.65 and the other gets 9.05… why? What are the judges looking for, or subtracting points for? And there are similar examples in other judged sports, too.
Re the technology Here are just a few of the things that are never explained on TV:
how do they measure swimming results to one hundredth of a second? How do they know A touched the wall before B?
in a swimming relay, what’s the rule about when the second team member can dive in? If the first guy has to touch the wall first, then (a) how does the second team member know whether he’s touched it or not, and (b) how do the judges know if the rules have been satisfied or not?
guy throws javelin and within seconds they show the distance to within a centimetre. How? I know it seems to involve some judge jabbing a stick in the ground that maybe they bounce a laser off, but I’d like the details.
long jump… they seem to know the exact distance within a few seconds. How? Unlike the javelin, I don’t see anyone sticking any measuring stick in the sand.
I feel sure there must be good online sources for all this stuff, but I just can’t seem to find it.
