Three mathematicians have derived the fundamental PDEs of #FluidMechanics, such as the compressible Euler and incompressible Navier-Stokes-Fourier equations, starting from hard sphere particle systems undergoing elastic collisions. They claim it resolves #Hilbert's sixth problem. By mathematically proving how individual molecules create the complex motion of #fluids, the three mathematicians could have helped to illuminate why time can not flow in reverse.

What variables affect #pressure?
The Under Pressure simulation allows students to explore pressure under and above water, as the change in fluid density, gravity, container shapes, and volume is varied.
