#42It's like a Tesla Valve for spreading butter evenly

Oh I dunno. I made a mm-wave radar with a Rotman lens using a generative loop between Python, Rhino, and EM simulation. Pretty sure AI could cook that up.
What did you use for the simulation part?
Custom FDTD for the optimizer loop, CST for final verification.

#44Looks deceptively simple. Is there a good source to learn more about how it works?
This looks like an optical Rotman lens: https://academy.lucedaphotonics.com/modules/awg/guide/compon...
Used to work in photonics. The star coupler portion is a Rotman lens, the whole thing is different (an AWG). It's used to spectrally separate an input (or in this case, inputs) across different outputs.

So the inputs are all the same spectrum and come out shifted by various amounts or something like that?

#46R.F Turner is a pretty nice example of nominative determinism. Parents up and named him "radio frequency dial", so of course he works in antenna technology
Similar to the plasma physicist R.F. Heeter

See link "Working with Luceda AWG Designer" on top of the page you linked. It's got a nice explainer.

Tito Beveridge creator of Tito Vodka, Ed Currie creator of the Carolina Reaper and Pepper X, Keith Weed the president of Britain’s Royal Horticultural Society, Usain Bolt one of the quickest people in the world, Thomas Crapper - commonly but incorrectly attributed with the invention of the modern toilet - founder of Crapper & Co plumbing company, meteorologist Sarah Blizzard, LEO Rob Banks, Donna/Mike/Bobbie Singer a…
I think nominative determinism has it backwards: people are actually nudged into careers which fit their names as whoever is on the receiving end of their services automatically has a more positive sentiment if they notice the name fits. I experienced this myself as my first name was rare in my generation and normally found in history books or literary classics so I was perceived through that lens.
That's what I understand to be the usual interpretation of nominative determinism.
Some studies have shown statistically significant effects from having aptonyms. More than the expected number of dentists named Payne, etc.

#49I wonder if you could do this with sea walls and gates and make beamformeable surf breaks.
The precondition is a controlled input, if you can provide that in the context of sea walls I think you have solved a much bigger problem.
Control is needed in directionality, which is pretty much solved - few tsunamis originate inland.
