Figure from Bill Unruh's paper, "Has Hawking Radiation Been Measured?". Unruh, W.G. Has Hawking Radiation Been Measured?. Found Phys 44, 532–545 (2014). https://doi.org/10.1007/s10701-014-9778-0 Figure is obviously drawn in MS Paint or equivalent. Shows a cut view of a waterfall going over a cliff. One yellow fish has gone over the edge and one has not. Green circles represent the acoustic wavefront of their yelling. The one going over the falls has its yell wavefronts shifted. The whole thing is adorable. Caption reads "Found Phys (2014) 44:532–545 535 Fig. 1 The sound waves emitted by a yelling fish as it goes over a waterfall which goes supersonic at the red line. Just as for a black hole, beyond the sonic horizon, the sound waves are swept over the falls with the fish. (Note that the appendages on the heads of the fish are ears, not fins, since these fish experience the world through sound, not sight"

Who wants to see the best figure of all time in a physics paper?
In which Bill Unruh explains black hole dynamics using the analogy of screaming fish going over a supersonic waterfall. 🧪

@thepunch.studio and @typofonderie.com coming through to fill my knowledge gaps left by Bringhurst.
Glad to see thepunch.studio bridging the gap to typeface creators from around the globe ✌️🧡🔠

The source of miniscule seems relatively straight-forward: small, when compared to capitals. But what is the source of capital in this context?
Does it refer to the upper portion of a column? I.e., the letter forms used to engrave words not he highest part of columns in the Roman world?

Love this, which I first learned about from @typofonderie.com 's amazing piece:
