I am not involved with that lecture in any way, otherwise I would not feel comfortable tutoring it on the side. So these exam questions are handed to me by the students I tutor, and they get them from the memory of other students. After exams they post all they can remember to a popular website...

Letting students explain it themselves is really powerful. I have learned a lot while teaching, so this certainly is true. The strange thing is that other medicine students that have passed this course said that just learning all the problems by heart has actually allowed them to pass. And they...

I am a pure physicist (M.Sc.) and on the side I do tutoring. Right now I have medicine students who have to take a physics course as part of their curriculum. Their course consists of one lecture (2 h/week) and a lab course with 10 experiments. The exam in the end are 20 questions where only the...

I will soon start a Master thesis in Lattice QCD. There I will spends lots of time developing C++ code and running it on different supercomputers. After that I consider doing a PhD if the Master thesis runs well. For the experimentalists I can see a lot of almost-engineering jobs where they...

In last week's seminar, a professor said that the chiral anomaly will lead to a lifetime of $10^{70}$ years. From this I conclude the following: The SU(5) GUT have lifetimes of sometimes less than $10^{35}$ years. Therefore the difference is so large, that one can consider the protons stable...

The pictures that you have posted look like a Hydrogen atom, not a harmonic oscillator. In quantum mechanics, there is no shell model, you have orbitals that are the states with the quantum numbers n, l, m_l. There are not really taken from any experiment, but they are needed coefficients...

Thanks for your replies, there a couple really nice points in there!

I had a debate with my dad today. At the core, there were questions like: How does the Higgs boson affect my life? Why do we spend so much money at CERN? Couln't they do smaller experiments? Why do we look for extraterrestial planets although we lack a decent spaceship to even get there...

Thank you, that is a nice idea. Calculus Physics sounds like a good followup to what I have been doing in school. Edit: Found something: http://ocw.mit.edu/courses/physics/

Hello, I just finished school and I want to study physics, but I have to wait about 1.5 years until I can start with it. What would you recommend to stay in touch with physics during that time? Reading books would be the thing I came up with, would you say that reading in forums like this...

The photon could collide with an electron from the atom as described in the Compton effect, pushing the electron a little. The photon will loose some of its energy (therefore frequency as well) and fly off in another direction. An electron could bump into another electron as described as well...

Make a drawing :)
