This summer I graduated from college, majoring in physics, but for reasons outside my academic career, I won't be able to attend graduate school for at least a couple of years. Despite that, I'd rather not neglect my physics education until grad school becomes possible.
I realize that a B.Sc. doesn't mean I should be able to read all the latest articles coming from the frontiers of research. However, I'd like to keep track of current affairs in physics to both be in touch with my field, and to help me decide on which sub-field I will focus once I return to the academia, and perhaps even decide where to go and under who to study. What would you recommend is the best way to do this, and what are the resources available that I should be aware of? (Note: I will probably not have access to paid scientific publications after I receive my diploma in the next few months)
Also, I wouldn't want my physics skills to rust in the meantime. Apart from participating here on the physics stack exchange, do you know of any good resources for physics questions/riddles/puzzles, hopefully at the appropriate level for a college graduate, so I can spend some spare time solving those to stay in intellectual shape in the next few years?
