 Sep 24 awarded Autobiographer Sep 4 comment In general relativity, are light-like curves light-like geodesics? I believe it should be $y(\lambda) = R\sin(\alpha\lambda)$. Jul 8 revised Definition of Kinetic energy Cleaned up the notation a bit and tweaked the wording in one place. Jul 2 revised Definition of Kinetic energy Added a linear motion example to the rotational motion example already given. Jul 1 answered Definition of Kinetic energy Jul 1 comment Definition of Kinetic energy Could you say more about the context? For example, are the v's supposed to be linear velocities, or would an example with angular velocities fit with what you are asking? How about curvilinear coordinates? Jun 18 revised Is there any other mathematical tool to measure velocity, instead useing derivative? Upon reflection I have decided the originally claimed connection between defining locally and calculus is obscure at best. Jun 16 answered Is there any other mathematical tool to measure velocity, instead useing derivative? Jun 12 awarded Fanatic Jun 8 revised Static as opposed to Kinetic Friction in Rolling Motion Added some more on how kinetic friction goes with rubbing, changed tank treads to tank tracks, and replaced one link with two different links. Jun 6 revised Static as opposed to Kinetic Friction in Rolling Motion Fixed up the wording a bit more. Jun 5 revised Static as opposed to Kinetic Friction in Rolling Motion Fixed up the wording a bit. Jun 5 answered Static as opposed to Kinetic Friction in Rolling Motion May 7 awarded Citizen Patrol Apr 28 revised Integrating factor $1/T$ in 2nd Law of Thermodynamics Fixed a typo in the last of the display equations. Apr 28 suggested approved edit on Integrating factor $1/T$ in 2nd Law of Thermodynamics Apr 24 awarded Informed Apr 12 comment What's the physical significance of the off-diagonal element in the matrix of moment of inertia I believe $\frac{\omega}{2}$ should be $\frac{1}{2} \omega^2$. Feb 12 comment Why quantum mechanics? I believe $| \langle a |\psi \rangle |^2$ should be $| \langle a |\psi \rangle |^2 da$. Dec 25 awarded Enthusiast
