We talk about theory a lot, both in and out of the ATM forum, and some of the discussions are very interesting. I do feel, however, that many (or most) of the major breakthroughs in the next ten years will come from the experimental side. Does anyone want to propose a good experiment or survey or discuss one that is already planned or under way? You wouldn't even necessarily need any access to equipment - there is a vast amount of publicly available data.
