18m	revised	Is anti-gravity possible in theoretical physics? added 3 characters in body
22m	revised	What force is responsible of anti-gravity? added 45 characters in body
1h	comment	What really are exotic supersymmetric black holes? @Dilaton: It is best to supply title, author, etc, of link, so we can reconstruct the link in case of future link rot.
2h	reviewed	Close Question on friction
2h	revised	Quantum master equation in the Batalin-Vilkovisky formalism layout
3h	comment	Fitting a circuit scheme to a simpler model Cross-posted from electronics.stackexchange.com/q/70364
3h	reviewed	Approve suggested edit on electrostatic repulsion that is troubling me
3h	answered	Quantum master equation in the Batalin-Vilkovisky formalism
5h	comment	Quantum master equation in the Batalin-Vilkovisky formalism Hi @soliton: Eq. (15.9.35) in Weinberg's book reads $(S,S)-2i\Delta S=0$, which is the conventional form, and without an extra minus. Is the extra minus something you derive?
7h	comment	If time stops at the speed of light is a photon 'everywhere' at once? Possible duplicates: physics.stackexchange.com/q/27794/2451 , physics.stackexchange.com/q/54162/2451 and links therein.
7h	revised	Is a photon “fixed in spacetime”? edited tags
7h	revised	If time stops at the speed of light is a photon 'everywhere' at once? deleted 6 characters in body; edited tags
10h	revised	Why is a degree Celsius exactly the same as a Kelvin? edited tags; edited title
10h	revised	How (why!?) does one introduce an UV cut-off in dimensional regularization? Please link to abstract page rather than pdf file
11h	comment	Differential equation (Greens function) satisfied by the kernel using path integrals According to Ref. 1 the eq. (2-25) only holds for $\Delta t>0$. See footnote 1.
11h	revised	Differential equation (Greens function) satisfied by the kernel using path integrals added ref to F&H so it becomes clearer in which context the question was asked.
11h	comment	Quantization as a functor Related: mathoverflow.net/questions/6200 and mathoverflow.net/questions/8606
11h	revised	Quantization as a functor deleted 24 characters in body; edited tags
