I'm an undergraduate in Physics and just cracked open some QM books, some seem to start with polarization and a strange way of introducing operators, while others start with the wavefunction and then go into harmonic oscilators, then the hydrogen atom etc.. What does polarization have to do...

Figured it out! It's exp(-2 *kappa *barrier thickness)

Homework Statement What is the approximate transmission probability (in %) of an electron with total energy 1.524 eV through a barrier of thickness 343 pm, and a potential height of 2.654 eV? (Does it matter what the potential energy is before and after the barrier? Not really, as long as it is...

Thanks guys, I aced the test, it all seems to easy to me now.

I have never done relativity before, my uni professor isn't good enough and I can't understand a word he says, he's all over the place. Anyway I missed a week due to being sick, and I just can't catch up, I am struggling to find any textbooks that have similar notation or help me solve...

Hey guys, I am new here, not sure if it's right place to post, but my girlfriend is finishing high school next year, she is interested in neuro-science as an undergraduate full-time course in the UK or Germany, I was wondering if you guys have any english textbooks you recommend her having a...

What about designing tech for Physics uses, or tech for Biomedical uses etc... I guess what it comes down to is an understanding of technology which is Electrical Engineering. Any specific classes you know of? I can attend any of the classes listed here...

Hey guys, so I'm just some teenager who is in first year Mathematics and Physics Bsc at University of Strathclyde in Glasgow UK. I am doing really well since it's first year it is so easy... I had a dream yesterday, where I designed some arbitrary piece of tech, and then after that I got...
