"Evolution Inside the Doughnut"
That's a direct quote from a slide (which was in English because originally it was part of a research presentation) from the atom optics lecture I heard this morning. This just shows that you can find interesting quotes almost anywhere. Of course the slide had nothing to do with evolution in a biological sense or with doughnuts in a literal sense, it was about Bose-Einstein condensates and their behavior in a "doughnut" waveguide. If you're interested in that do a google search for "doughnut" "evolution" and "Bose-Einstein" and links to this stuff show up. Anyway, my associations with the slide title "Evolution Inside the Doughnut" were far more amusing than the actual topic...
