All external forces should be considered at the points where they act on the body. D is acting on point Q in the figure you show. But...

Pursuiting the calculation I showed $$\hat{L}_z=-i \hbar \frac{\partial}{\partial \phi}$$ I am not sure whether it is consistent with...

We are tempted to say such and such momentum at such and such place, but QM uncertainty relation or commutation relation...

Inserting $$\mathbf{p}=-i\hbar \nabla$$ in formula of L, you will prove that L has no r dependence.

We may take the problem as a study subject of statistics, sending a questionnaire to the captains: a. How old are you? b. Have you...

Salt matter condense up from 1% to 2% (doubles) by more than 50% water evaporation seems to be reasonable.

But the point of the video is to teach us how to use the lambert function to solve a problem not how to intelligently guess the answer...

$$g_{\mu\nu}g^{\nu\rho}=g_{\mu}^{\ \ \ \rho}$$ $$g_{\mu\nu}g^{\rho\nu}=g_{\mu}^{\rho}$$ $$g_{\nu\mu}g^{\rho\nu}=g_{\ \ \ \mu}^{\rho}$$...

With no loss of generality a<b $$f:=\ln \frac{b^a}{a^b}=ab(\frac{\ln b}{b}-\frac{\ln a}{a})$$ Sign of f decides which is larger. The...

They are the same because g is a symmetric tensor.

I noticed the following question generated quite a lot of interest on the Internet. Which is larger ##e^{\pi}## or ##\pi^e##? Most (if...

If the goal is to learn about the 1s state of the electron, then you are of course correct that performing two position measurements...

The pair of events I would refer is I should have stated clearly that measured space coordinate values of the electron are used to...

We don’t. Proper time is the length of a path through spacetime between two events; the electron has no path or position so the notion...

Quantum field theory treats the decoherence between the system and the measuring apparatus, but does it not fail to account for the...
