Imaginarium:

A made-official-by-community archive of open problems in condensed matter physics would be cool. Open for anybody to read or contribute, and sorted by keywords even. I wonder if anybody would be brave enough to post an open problem they actually deemed both cool and tractable, and if it could ever catch on and work for the benefit of the community?

Thoughts and musings about research habits and skills:

The explicit discussion of concrete ways to improve as a researcher is something you encounter surprisingly little of in my experience, at least within physics as far as I’m aware. I like to experiment with different ways to work and develop new skills, and might write down bits and pieces now and then related to this. Probably everything I view as a profound realisation in my own life sounds trivial on the face of it, but if, upon digging further, it was in fact non-trivial to me then perhaps I’m not the only one.
