The Magnus effect is an observable phenomenon that is commonly associated with a spinning object moving through air or another fluid. The path of the spinning object is deflected in a manner that is not present when the object is not spinning. The deflection can be explained by the difference in pressure of the fluid on opposite sides of the spinning object. The Magnus Effect depends on the speed of rotation. The most readily observable case of the Magnus effect is when a spinning sphere or cylinder curves away from the arc it would follow if it were not spinning. It is often used by football players, baseball pitchers and cricket bowlers. Consequently, the phenomenon is important in the study of the physics of many ball sports. It is also an important factor in the study of the effects of spinning on guided missiles —and has some engineering uses, for instance in the design of rotor ships and Flettner aeroplanes. Topspin in ball games is defined as spin about a horizontal axis perpendicular to the direction of travel that moves the top surface of the ball in the direction of travel.

I was recently studying Blackbody Radiation and the principle behind it as far as used in the Plancks original paper is to find the energy distribution which maximizes the number of ways in which energy quanta can be distributed. In so far as I'm aware, there is not direct connection between the two as you might like, however there are a few things that might be worth mentioning. I will take this back a few steps from the question itself because I feel there's some important context to the point I would like to make in The Principles Of Physics Behind The Sport end. Since the problem at hand is looking for a steady-state distribution, the Liouville theorem or its equivalent Tne a quantum system implies that the probability distribution we seek must Poisson commute with the Hamiltonian, and hence can only be a function on the conserved quantities of the system. A key OOf that's often overlooked is that there's more than one way to do this. One would be to assert that the distribution is simply a constant.
This would give the distribution associated to the microcanonical ensemble. Perhaps more common is the assumption that the distribution depends only on the energy Hamiltonian.

Now, another important fact to understanding things lies in probability theory itself. Entropy maximization perhaps the best understanding of what this should really mean to us actually comes, I think, from information theory and signal processing -- the application Shannon originally invented the notion of entropy to deal with. See for example Cover and Thomas' bookis a fairly good principle all things considered, but alone this doesn't do much for us, we need constraints as well. In general, we might say that we know something about a system, and it might be convenient to assert that this something takes the form of an expectation value, which we assume to be a fixed, known quantity. For a nice discussion of how entropy maximization works in the presence of constraints, see here. Roughly the same arguments work out in the quantum case as well. In the quantum case, we find the density matrix to be the Boltzmann factor, but with the Hamiltonian operator rather than function.
I believe I recall a nice discussion of this appearing in the conformal field theory book by Di Francesco, Mathieu, and Senechal. Finally now we can come to the principle of least action. Integrals of this form can often be approximated by asymptotic series. For example, see here. As an aside, this is the approximation working in the background any time you see Feynman diagrams floating about.
That is, the solution which extremizes the action. This may feel like an unsatisfactory connection between stationary action principles and thermal physics, but it is nonetheless the only connection I can think of which is technically accurate. Sign up to join this community.
