7h	revised	Hamiltonian in 2-dimensions? Dear user1429566, if u don't like my changes please roll back or use the parts u like.
7h	comment	Simulation of physics of chains/ropes in force fields resources? Please edit it.
8h	revised	Does the measurement on a subatomic particle give its mass value? deleted 5 characters in body; edited tags; edited title
9h	revised	Quantum mechanics Perturbation theory edited body; edited tags
9h	revised	Evidence for expansion of space edited tags
9h	revised	A tank full of water has a small hole at its bottom It seems the homework tag applies even if it is not actual homework
15h	revised	Cosmic Microwave Background (CMB) and its relation to Inertial Frames edited tags
16h	revised	According to Hubble's Law, how can the expansion of the Universe be accelerating? edited tags; edited title
16h	comment	How much force is required to lift this car (all details/info provided)? Related: physics.stackexchange.com/q/52701/2451
19h	revised	Applications to the Van der Pol equation? added 55 characters in body; edited title
19h	comment	How much force is required to lift this car (all details/info provided)? Also note that it is better to provide relevant information (e.g. weight of car) in the question formulation itself rather than in external links, which may be prone to future link rot.
19h	revised	How much force is required to lift this car (all details/info provided)? It seems the homework tag applies even if it is not actual homework
19h	comment	Conformal Compactification of spacetime Minor comment to the answer (v2): It is best to supply title, author, etc, of link, so we can reconstruct the link in case of future link rot.
20h	reviewed	Close Who (and Why) started the “electrons are negative, protons are positive” convention?
21h	revised	When do I apply Significant figures in physics calculations? edited tags
