Inverse problem and Bertrand's theorem, Yves Grandati, Alain Bérard and Ferhat Ménas, Am. J. Phys. 76, 782 (2008).
Bertrand’s theorem is formulated as the solution of an inverse problem for classical one-dimensional motion. We show that the solutions of this problem, if suitably restricted, can be obtained by solving an elementary equation. This approach provides a compact and elegant proof of Bertrand’s theorem.

The lock and key paradox and the limits of rigidity in special relativity, E. Pierce, AJP 75, 610 (2007).
According to special relativity, a (longitudinally) moving stick is Lorentz contracted. When it is brought to rest, it must expand to its proper length. But, exactly how this expansion unfolds depends on how the stick is stopped. If the front end hits a brick wall, the rear end must (briefly) continue moving, and the stick contracts even further before expanding; if instead the rear end is suddenly stopped, the front end (briefly) continues, and (surprisingly) the stick overexpands before settling into its proper length. These effects of overexpanding and overcontracting are independent of any classical or molecular elasticity, but are derived entirely from the limits of information travel time imposed by special relativity. I explore these phenomena, inspired by the little known “lock and key” paradox.
