Say I want to do molecular dynamics simulations on a crystal of a specific substance. I get on Scopus and search for it, say going back a couple of years with the results, and then I also check the references in these papers. How can I be kind of sure that this background research is adequate?

I feel like asking about USPEX is already too specific,so I just want to see what people think of it. How do you think it compares to other methods of predicting crystal structures?

By three professors I mean we are split into three groups.The whole semester is done by the same professor.Each student attends one professor's classes. The problem sets are graded by the 2nd year students precisely in order to know if the student put effort into it.Blank papers obviously don't...

I am not arguing with anyone.I was perplexed with the other prof's extreme attitude towards it and wanted to know if this was a practice below the average standards of universities around the world,which I think should concern any engaged student. From the replies here I've gathered it's indeed...

I should point out at that you only got the bonus grade if your grade was already 5 or greater,so it doesn't help you pass. I understand that we shouldn't be rewarded for participation and I agree.But the professor I mentioned seemed opposed to the fact that there were students grading the...

In my first year in undergrad ,Calculus 1 was done by three different professors all three of whom followed the same practice: We were delivered a problem set every week and we were to upload our solutions online(on Blackboard) for grading.Students that had delivered over half of the problem...

I'm sorry but I didn't find any other place appropriate to post this other than General Physics. Say I have downloaded a pdf of a paper that's not open access for free via my university's VPN connection.Is it legal to e-mail the pdf to someone else?

Wonderful article on the subject by Prof. Philip Moriarty(of SixtySymbols fame) from a couple of years ago.Recommended reading to all: http://www.nottingham.ac.uk/~ppzstm/pdfs/papers/2014/moriarty_visualizing.pdf

Try to simplify the equation,you will get to -1=1,which of course isn't true.So the equation isn't true for any x.

If you raise any negative to an even power(like -4) it gives something positive.

There is no value for which it is true.Try and prove it.

Seeing it in this form might help you: ##U=\frac{q_1q_2}{r} ## So,does ##r=\frac{U}{q_1q_2} ##?

No.And it's the correct equation.The fraction is mot correct,though.

Try solving for r again,you've made a mistake.

V is potential. U is potential energy.
