They could have at least given a link to a paper detailing what he found

Maybe in that mess, somewhere.

If he is 16, that has got to have been the 16 hardest years ever. He looks much older.

Seriously. Considering Indians age verrrrrrrrrry well.

The first says its it to do with "flow resistance", the second talks about balls rebounding off a wall
If I was a physicist I might be more excited

I know lots of 16 year old boys who look old. Im 20 but i look like 22-23 old guy, well because of my height. ( Im north Indian )

So wheres the ball?

The article is terrible, describes nothing about the problem he solved.

The problem involved calculating the path of a projectile that is subject to both gravity and air resistance. Ray also solved a second problem, involving a body colliding with a wall, as part of a school project.

That makes sense. So... add air resistance to kinematic equations [easier said than done]... I can see that.

The second one... object colliding with a wall. An exact analytic solution would be nice. Although it probably includes a number of simplifying assumptions. Is the ball compressible [like a spring]? Does this only work for balls, or other objects as well?

Apparently the solution was already implicitly known [but still impressive if independently determined]: http://www.df.uba.ar...mechan/air0.pdf

As for the rest... it's in this picture, but hard to see... and in German...

Easy way to check his age.
