Things I wish I had learned at university: - measuring the efficiency of an algorithm in watts - difference between classical math and computation - relationship between geometry and number theory

I recall seeing some literature on a concept called “reversible computing” that seemed to be about this too. I guess that’s the synthesis side of power efficiency analysis.

Reversible computing builds on the realization that entropy results from deleting bits. By building gates that permute bits only, you may be more efficient (but you'll still have to flush out the superfluous bits at some point). Best effort computing is largely unrelated.
