Analytical solution of two fundamental unsolved problems of particle dynamics
Two problems in classical mechanics have withstood several centuries of mathematical endeavor. The first problem is therefore to calculate the trajectory of a body thrown at an angle in the Earth's gravitational field and Newtonian flow resistance. The underlying power law was discovered by Newton (17th century). The second problem is the objective description of a particle-wall collision under Hertzian collision force and linear damping. The collision energy was derived in 1858 by Hertz, a linear damping force has been known since Stokes (1850).

This paper has so far only the analytical solution of this approximate or numerical targets for the problems solved. First, the two problems are solved fully analytically. For the first problem will be investigated further using the analytical solution, the physical behavior of the system and set up outline solutions for generalized models. For the second problem is carried out in order to increase efficiency and convergence control a semi-analytical optimization. Finally, the analytical results are compared with numerical solutions so as to validate accuracy and convergence to numerically."

Stated separately:

"The student went to the TU Dresden in order to evaluate the raw data of direct numerical simulation, ie the trajectories that approximately describes a ball. He noted that an exact equation of motion is missing - and decided to change that. For months he worked on the differential equation, calculated and rejected, of course, in his spare time, because the dedicated non-school Tuesday afternoon, so rich is not enough: ". The ideas are not just for this afternoon fix or restrain" The historical moment in which he should have registered in schoolbooks future is, however, account for him, when Ray came up with the solution, saying he no longer can. But that there were "many blind alleys" were - and that the node must have burst "somehow in the subconscious."

Interesting that something seemingly as simple as knowing how a ball will bounce off a wall has evaded a differential equation for 350 years...

way to go, MB. youre proof that after second childhood comes second adolescence. lol you must be taking your iodine and boron.
