that slang use of 'of' didn't strike me much, one gets used to seeing it around on the internet (especially where younger people frequent) and I tend to think people really know better than that and use it sort of on purpose among chums on forums so they don't stick out like being unduly proper (for similar reason you don't see me here capitalizing and dotting sentences with the result I am running one paragraph sentences, its 'internet forums' grammar' - don't learn from me <img src="/images/icons/smile.gif" />) but that account of education and mention of 'ebonics' made me feel sick and sorry (word itself strikes me also as scarry like some black woodoo mysticism), that is simply horrible, a chilling story of modern education that one thinks cannot be for real but is seems it is being practiced out there, enough said<br /><br />as for the speed of light, that's pretty good thinking, I had that idea some ten years ago but I was thinking in terms of sprinters on relatively short racing track, like two hundred meters one or even the one hundred metter classic track<br /><br />the idea was that you imagined the racers to push some sort of carts running on tracks by their chests as they sprinted over the track length, initially they would be gaining speed fast but that would soon level off and they would never exceed the track record speed, depending on the weight of that cart, they would even run slower times<br /><br />if the carts were made lighter and lighter (which would be equivalent to adding manpower or donkey power) untill they were pretty negligible weight which would be almost the same as racers running free without pushing anything, they would still top out at certain speed near the end of the track which would result in them making the track record times and nothing more<br /><br />making those carts lighter is equivalent to using lighter and lighter particles in particle accelerators which would enable the accelerator electromagnetic forces to impart to them speeds <div class="Discussion_UserSignature"> </div>
