Take a look at this question. It will clear your doubt physics.stackexchange.com/questions/113232/…

comment How to calculate the value of gravitational acceleration of my town
Both the formulas hold for different situations. I am thinking out loud here but I think what if we applied the latitude formula first to find the effective $g$ at that point and them used that value of $g$ as $g_0$ in the altitude formula, we might get a more precise value of g at the town which takes both factors into account? I am having doubts because as Qmechanic pointed out in the comment that the assumption that the earth is spherically symmetric (as we did in deriving the altitude formula) is inconsistent with the fact that earth is spinning.

comment How to calculate the value of gravitational acceleration of my town
Well, I plugged in the numbers into both formulas. And the 'altitude formula' gives a value of $9.79m/s^2$ and the 'latitude formula' gives $9.77m/s^2$. (I stand corrected, both of them give nearly equal values)

comment How does this “simple” electric train work?
Thank you for the explanation. Is the Lorentz's Force law F=q(vXB) the main equation behind this?

This paper has exactly what you're looking for: arxiv.org/abs/1207.2146 (Unveiling the Higgs mechanism to students by Giovanni Organtini)

comment Fringe Pattern Brightness for Young's Double-slit experiment
To explain the theta dependence you have to derive the diffraction integral which requires calculus.

comment Fringe Pattern Brightness for Young's Double-slit experiment
The brightness will be equal if you consider the effect of interference only. But the brightness will fall off if take into account the phenomena diffraction along with interference.

I would definitely look it up. Thank you. This discussion has been very helpful.

comment Principle of Caratheodory and The Second Law of Thermodynamics
I still can't see how the concept of increase of entropy comes out of this for an irreversible process. ( I'm getting the feeling that this works only for reversible processes ).

Can you elaborate on point 2? How does this distinction exactly melt away?

comment Physical motivation for differentiation under the integral
Actually the examples from Quantum mechanics would show how neat (and essential) this trick is.

comment What are some good resources for learning how to apply vectors in physics?
See, what you are actually doing is taking the projection of the vector along the line joining a vertex to the center. Think along this line and you shall find the answer.

comment What are some good resources for learning how to apply vectors in physics?
It is a very simple problem. Think about the angle that B makes with the line joining the center and taking the cosine component

You can post that specific problem here as a homework question and everyone can take a look.

comment What are some good resources for learning how to apply vectors in physics?
That is a very difficult question to answer. The book is a very popular one and I personally recommend it. It would be wise to download the ebook and go through it buying to see if you are comfortable with it.

Carefully reading Resnick Halliday and going through solved examples and finally solving problems on your own is the only way.

comment Why have $n$, $\ell$, $m_\ell$, $m_s$ been picked as quantum number symbols $\mathbf{\text{in this order}}$?
The $n$ we get by solving the Schrodinger's equation for Hydrogen atom can be interpreted as the allowed Energy State.Actually it is one of the constants we use conventionally while solving the azimuthal equation. Historically, Bohr introduced n in his quantization of angular momentum postulate where n is the allowed orbit. Mathematically,$L = n{h \over 2\pi} = n\hbar$ where $n=1,2,3...$ was called the principle quantum number.Obviously, starting from Bohr's postulate we can also arrive at the expression for energy.The two thus become equivalent, in retrospect.I will make the necessary edits.

I think that you would have to link the video here via some website like Youtube.

comment Why have $n$, $\ell$, $m_\ell$, $m_s$ been picked as quantum number symbols $\mathbf{\text{in this order}}$?
I think it was due to the fact that the constant in Legendre's eqaution is conventionally as written as $l(l+1)$. But this is merely a speculation.

comment Expectation Value of a Dynamical Variable
So, we can view expectation values of an operator as nothing but as inner products? And this follows from Operator Theory?
