The FQXi community, a great physics site, has an annual essay contest. Winners of last year's contest--on the subject "What is Ultimately Possible in Physics?"--have just been announced. You can follow the link to read the winning essays. Worth your time. It's philosophically interesting to note the considerable number of essays discussing whether a "complete theory" of the universe is a feasibility. But this is not the only reason to check these out.
