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.

An Indian teenager in Dresden supposedly came up with a new closed
form solution to a trajectory in the presence of air resistance.
Apparently, it assumes quadratic drag. There's a derivation here:
