No, it isn't "what will be the final outcome of the American congressional elections?" (for which voting begins any time now), nor is it "will Australia descend into the 7th level of hell because a new form of embryonic stem cell cloning has been made legal?", but it is that time eternal question:
"What should my theorem prooving, paper editing, all purpose mathsish physicish caffeine-based fuel source be, this gigantic packet of m&m's sitting on my desk or the watery-as-hell-yet-still-somehow-tastes-like-mud coffee that comes out of the office coffee machine?"
I think that time will come to proove that the correct answer will be, "all of the above and maybe something more".
