One page 24 of his book on classical field theory (4th edition), Landau derives the relativistic equation of motion for a uniformly accelarated particle. How does he get the differential equation that leads him to his result?
Yes, that is correct. All I am trying to do is to expand psi in terms of of the energy eigenstates. My derivation for ## \braket{E,a}{\psi}## is based on the one leading to 4.3.11a. The only initial condition is psi at t=0, which does not matter for U(t). I still cannot reconcile my result with...
This is a question for those with Shankar in their disposal. When studying from this book, Exercise 5.1.1 puzzled me. Now, it is easy to solve the exercise from 5.1.9. However, how would we expand psi in terms of the energy eigenfunctions,* if we did not have 5.1.9*, but instead started fresh...
Hari Seldon. HE CAN SEE THE FUTURE USING MATH. YES, HE DOES SO THROUGH STATISTICAL ANALYSIS APPLIED TO LARGE POPULATIONS, BUT HE CAN STILL PREDICT WHAT THE GROUP WILL DO TO A SINGLE PERSON. HE IS AWESOME.
This is a question to those who have the 3rd edition at their disposal. Where do 3.45 and 3.46 come from? I understood everything he said before that...
The book that I use (Concepts in Thermal Physics by S. and K. Blundell) states the second law in two ways. The way they state the Kelvin version is "no process is possible whose sole result is the complete conversion of heat into work." How does that fit in with the isothermal expansion of an...
