I’m biting my lip opening my mouth again…
But this theorem if proveable is much more important than the dolphin skin thing.
But since artificially reproduceable boundry layer cutaneous ridges(muscle and sponge) was a favorite topic of mine when I had dreams to be another Jacques-in-the-Box UW Physical Oceanographer in the 1970s when everyone else was getting stoned or shot. Here some additional reads.
Gray’s 1936 dissertation and MO Kramer’s stuff was what I was following back then but Carpenter has published alot more recent stuff:
I’d attach them but they are too big.

Nothing to do here with fighting with each other or the wood or other petro chemical stuff discussed here though
A proveable Unified Theory is very important though
Just wondering if the guy thought so hard on this that all his hair fell out and all the others genius’s like Albert didn’t…
I guess that’s the price of a breakthrough…
