That’s how I got mitochondria.

~ Randall Munroe, from Stromatolites

No one asked me, but if I was asked to summarize Munroe’s work I’d say: He’s mastered the art of finding insight by shifting the scale. Why is that hard? Why is that helpful? Why is that great? Because to it at the mastery level (as Munroe does) requires one to have integrated a lot of knowledge. A lot.
