A German 16-year-old has become the first person to solve a mathematical problem posed by Sir Isaac Newton more than 300 years ago.
Shouryya Ray worked out how to calculate exactly the path of a projectile under gravity and subject to air resistance, The (London) Sunday Times reported.
The Indian-born teen said he solved the problem that had stumped mathematicians for centuries while working on a school project.
Ray won a research award for his efforts and has been labeled a genius by the German media, but he put it down to "curiosity and schoolboy naivety."
"When it was explained to us that the problems had no solutions, I thought to myself, 'well, there's no harm in trying,'" he said.
Ray's family moved to Germany when he was 12 after his engineer father got a job at a technical college. He said his father instilled in him a "hunger for mathematics" and taught him calculus at the age of six.
Ray's father, Subhashis, said his son's mathematical prowess quickly outstripped his own considerable knowledge.
"He never discussed his project with me before it was finished and the mathematics he used are far beyond my reach," he said.
Despite not speaking a word of German when he arrived, Ray will this week sit Germany's high school leaving exams, two years ahead of his peers.
Newton posed the problem, relating to the movement of projectiles through the air, in the 17th century. Mathematicians had only been able to offer partial solutions until now.
If that wasn't enough of an achievement, Ray has also solved a second problem, dealing with the collision of a body with a wall, that was posed in the 19th century.
Both problems Ray resolved are from the field of dynamics and his solutions are expected to contribute to greater precision in areas such as ballistics.

Sooooo......

If no one could ever solve it, who can confirm his answer is right????

[ROFL1]. Seriously though?

Sensational journalism.

What the kid did was create some ballistics tables. Ho hum

I suspect he derived an equation from kinematic and force equations. I wish they would have showed the math. It would be neat to see. I've seen an article about civil war cannon ballistic "triangles" used by artillery officers and comparing them to current physics. The results were suprisingly close.

Less than a month before he's dead and his data is in an "app"

Here's the math.

Calling BS on this. No possible way this problem was unsolvable before this German kid came along. Frankly the physics involving ballistics is extremely well understood and accurately modeled/predicted , and has been for many decades if not hundreds of years.

My first problem here is that the Germans use different symbology than we teach here, but it seems straightforward, from what I can discern. My undergrad was Mathematics, specializing in Algebraic systems, although it's been 25 years since I've used the stuff.

Did you read the linked article? In it, the authors state that the claim that the problem was unsolvable was in error, so you would be correct.

Nevertheless, all his steps are basically known to experts, an we emphasize that he did not solve an open problem posed by Newton.

Smart kid, but he didn't solve any centuries old problem.

Sir Issac Newton is one of the smartest physicist in recent history.

The reason Sir Issac Newton could not solve this problem at that time was, because ODE (Ordinary Differential Equations) wasn't available at that time.

Most of aerodynamics/aerospace equations requires ODE and some PDE (Partial Differential Equations) on a graduate level.

For 16 year old kid to solve this problem, he probably had to take 1st semester calculus at the age of 14. [Coffee]

I've seen some guys who took higher level of MATH at a same age, but they didn't do good on graduate level engineering courses.

The real question is, How is is all this math going to help him get laid?

Nothing too fancy there. If his father can't comprehend that math, then he shouldn't be an engineer, or for that matter an engineering professor.

hahahaha. I would say you are correct for High School, or U of CA school.

I think almost every other text books uses a different symbology even in US.
Also, some classes uses same symbology, and means totally different thing.
That is how I had a huge misunderstanding on Econometric. They uses same "hat" and "dots" on the variables as Physics, and it means totally different thing.

Sometimes the mathematical solution is very straightforward, but what's usually important is having a new approach to the problem. Physics has been advanced mostly in very small ways over many years and only a handful of people have made a huge impact.

A case in point

I have a bachelors degree in math and I was impressed. While reading the solution it gave me flashbacks of being in school and not understanding what the hell I just read.

Now if you figured out how to make a spaceship go faster than the speed of light that would be genius...and yes it can be done!
