About 97-98% over my head, but so interesting, so exciting! My heart is beating very fast because of this subject matter. Knowing that there are people like Demis is a promise of a brighter future than the gloom of political hijinks portends. I wonder what science fiction Demis reads. The Hitchhiker’s Guide, obviously, but besides that. (Btw, the answer is 54, not 42, unless there are more obscure uses of basic mathematics than I’m acquainted with.)
