Wish I’d known this before reading the tunny report. At the same time, it’s fascinating to see how folks in 1940 arrived at the same theory The rest of the series looks just as interesting.

Why do physicists despise Clifford algebra? Because it opens their field to a hundred million open minded computer science students, eager to unify. Put Clifford algebra into the heart of year two cs math, its game over.

Excellent intuitions about why for Gilbert spaces and field embedding one is interested in constant functions on cosets. Contrasts nicely with the stats motivation that is the background to the (colossus aided) counting attack on Tunny cipher (and certain aspects … Continue reading
