Yesterday my attention has been attracted by the following article…

http://www.huffingtonpost.com/2012/05/27/shourryya-ray-16-year-old_n_1549172.html

It seems that a 16 old student named Shouryya Ray and ‘dubbed Genius’ has ‘cracked’ a puzzle that Isaac Newton proposed 350 years ago and that nobody solved till now. Ray says that the use of the computer had an essential role in his ‘memorable enterprise'. The ‘Newton’s Puzzle’ seems to be to find a procedure to arrive at

**exact calculations of a trajectory under gravity and subject to air resistance**…

Very well !... it is well known the fact that journalist often combine ‘exaltation of myths’ and poor knowledge of specific arguments, so that probably the article has to be read carefully and many statements put in right prospective. For example it seems that such type of problems has never been seriously studied and that is of course is a nonsense. The air resistance plays an essential role in the motion of a projectile of artillery and artillery did exist also at the times of Romans … and even before!...

Anyway such type of problem is interesting and actual also in the 21-th century, so that some year ago I found practically the procedure to arrive to the solution of this problem and the computer didn’t play any special role in that. About the ‘motivation’ that pushed me to ‘attack’ this problem we will discuss later . Before showing You the procedure I used, it would be interesting some comments from You…

Kind regards
