I'm reading through Stephen Hawking's 'A Brief History of Time' and came across this sentence in the second chapter: " If the law were that the gravitational attraction of a star went down faster or increased more rapidly with distance, the orbits of the planets would not be elliptical, they...

Thanks for clarifying this!

I know how to work through this problem but I have a question on the initial separation of the wave function. Assuming ##\psi(\rho, \phi) = R(\rho)\Phi(\phi)## then for the azimuthal part of the wavefunction we have ##\Phi(\phi)=B\left(\frac \rho\Delta cos\phi+sin\phi\right)##, but this function...

On page 298 of Shankar's 'Principles of Quantum Mechanics' the author makes the statement : ""In an arbitrary ##\Omega## basis, ##\psi(\omega)## need not be even or odd, even if ##| \psi \rangle ## is a parity eigenstate. "" Can anyone show me how this is the case when in the X basis...

This was exactly what I was looking for, thank you! Thanks to everyone who replied also, it was all very helpful.

Thanks for the reply. I have tried the expansion and believe I can show that the operator series does not converge but I don't understand what the significance of this result is. Does it mean that because the series does not converge that the operator has no physical reality for that particular...

Hi All, I've been going through Shankar's 'Principles of Quantum Mechanics' and I don't quite understand the point the author is trying to make in this exercise. I get that this wavefunction is not a solution to the Schrödinger equation as it is not continuous at the boundaries and neither is...
