If you calculate the force acting when a fluid with density \rho and velocity v flows through a narrowing which transverse section is S, you'll obtain \rho v^2 S . But if you think of the ski just like a narrowing which transverse section is S = tan(\alpha) A and you think of the fluid like...

Aniway I think isn't so simple go back to Lorentz Poincaré Larmor Fitzgerald aether after then Einstein go forward to general relativity. A consistent general aether theory includind gravitation could pretend probabilly an entirily new formulation of physic's laws. Actually quantum gravity could...

I'm not sure about the sentence "all variables and given/known data". In fact I succeed in order to obtain a relation between: \left(\frac{\partial s}{\partial T}\right)_p and c_v, \alpha, k_T, T, v just following the mapes's hint to consider S as a function of T and V. Where minuscle...
