As a slimy mollusc (actually, I seem to have been evolving and devolving wildly over the past few weeks – today it seems I am a flippery fish, but I doubt that'll last), I tend not to bother linking to interesting or amusing things, assuming that readers are much more likely to see the thing where I saw it than to need me to point it out to them. But what's the harm, right? If you've seen it already then don't bother.
Here is manifested a standard of candor in student papers (physics division) that we all wish were more common (or at least occasional). HT's: Evolving Thoughts, Pharyngula.
