Re: [math-fun] Shouryya Ray's equation
There's a long debate in Wikipedia, or maybe Wikimedia, on whether to delete an article on Shouryya Ray. The consensus seems to be that there is no verifiable source, other than the media yammering to itself and copying each other's yammerings. There are also assertions that the equation in question was already discovered in the late 1800's. My guess is that the teenager actually did rediscover some equation that he did not know was not new, and the world press -- with a collective IQ below room temperature -- has just parroted what was on his science fair project. --Dan << An Indian teenager in Dresden supposedly came up with a new closed form solution to a trajectory in the presence of air resistance. Supposedly, the solution involved cos, sqrt and _asinh_ (this last one is what intrigued me). However, I haven't been able to find his actual paper after consulting with Google. Does anyone here have the reference or link ?

Apparently, it assumes quadratic drag. There's a derivation here: http://www.reddit.com/r/worldnews/comments/u7551/teen_solves_newtons_300year... Sincerely, Adam P. Goucher
If anyone's German is up to scratch, then you may be able to make some sense of his poster, which is available (though only partially visible) here: http://img838.imageshack.us/img838/8750/mshouryyaray.jpg The highest ranking answer on the physics.stackexchange discussion ( http://physics.stackexchange.com/questions/28931/what-are-the-precise-statem... ) seems to have analysed the poster. Essentially, Ray works out series expansions for u and v, and then somehow works out the conserved quantity Adam provided. Apparently, the book referenced in this post ( http://www.reddit.com/r/math/comments/u74no/supposedly_this_is_a_new_formula... ) (the book is in French) discusses the formula as well.
