Unsolved Scientific Problems in Classical Mechanics

Click For Summary
Key unsolved problems in classical mechanics include the complexities of fluid dynamics and turbulence, which remain challenging for scientists, as exemplified by the difficulties in understanding bumblebee flight. The N-body problem continues to be unresolved, with only a few specific cases having solutions since its introduction by Newton. Additionally, there is a noted absence of a classical mechanics-only approach to geometric phases in chaotic systems. These issues highlight significant gaps in the understanding of rigid body mechanics, deformable-body mechanics, and fluid mechanics. Addressing these problems could advance the field of classical mechanics significantly.

Hallo Everyone,

What are the most important unsolved problems in Classical Mechanics especially related to mechanics of rigid body mechanics, deformable-body mechanics and, fluid mechanics.

I have read that complicated fluid dynamics and turbulence is still a beast to deal with.
e.g. http://www.livescience.com/33075-how-bees-fly.html -- scientists took a while to figure out how bumble bees generate enough lift for flight.
 
For classical mechanics, the N-body problem is still unsolved, except for a few special cases. It's been around since Newton.

Not sure if important, but I think there is still missing A classical mechanics-only approach to geometric phases in chaotic systems .
 

Thread 'Is energy really conserved?'

I built a device designed to brake angular velocity which seems to work based on below, i used a flexible shaft that could bow up and down so i could visually see what was happening for the prototypes. If you spin two wheels in opposite directions each with a magnitude of angular momentum L on a rigid shaft (equal magnitude opposite directions), then rotate the shaft at 90 degrees to the momentum vectors at constant angular velocity omega, then the resulting torques oppose each other...
