Ok, so the sky is blue because of Raleigh Scattering - blue wavelengths of light scatter off of atmospheric particles in the air (more/easier than others) - I understand this pretty well. So, if our atmosphere had a different chemical composition, would the sky be a different color (barring thing...

In the analysis of coherence and interference, I encountered the following expression: $$F(t)=\Re\int_0^\infty\mathrm d\omega e^{-i\omega t}H(\omega)$$, where $\Re$ denotes the real part of the integral, and $H(\omega)$ vanishes for $\omega<0$. I want to show the Fourier transform of $F(t)$ is $$...

Since a bridge rectifier converts ac to dc. Will this charge my capacitor to max capacity how hooking it up to a battery would? The positive is charging the anode, while the cathode is grounded. Any reason why this circuit would not work? When just trying to convert ac to do soley for the purpose...

Assume we have a real Klein Gordon field $\phi(x,y,z,t)$, and we do the non-relativistic expansion of it in terms of a complex field $\psi(x,y,z,t)$ $$\phi=\frac{1}{\sqrt{2m}}(\psi e^{-imt}+\psi^* e^{imt}).\tag{1}$$ Notice that in the non-relativistic limit, $\psi$ obeys the Schrodinger equation ...

At which point inside a circular current carrying loop the strongest? Some sources say it is at the centre and some say it is at the circumference. And how can we mathematically prove this? And also, is the magnetic field line through the centre of the loop exactly a straight line? Because this d...

Someone looks at me. Now, he knows my position and my momentum, with some uncertainty. Therefore, he hasn't measured neither my position not my momentum, since neither is known perfectly. He measured some other observable $O$, and found me in some eigenstate of $O$: $|\psi>$. $|\psi>$ is such tha...

I found these questions online and was amazed by how organized this book was so it would be really helpful to know it's name
