In this Insight, I will answer Wheeler’s question per its counterpart in quantum information theory (QIT), “How come the Tsirelson bound?” Let me start by explaining the Tsirelson bound and its relationship to the Bell inequality, then it will be obvious what that has to do with Wheeler...
But when you do, it is awesome, in both the new and old senses of that word. (The sequel to this piece—Why language-oriented programming? Why Racket?—is devoted to this topic.) Libraries & documentation. [Racket] This might not look like a competitive ...
“we’re using bits to help us share atoms.” when uber and airbnb first arrived, they wore the halo of this broad sharing phenomenon. in july 2012, alexia tsotsis penned a glowing early profile of uber in wired. “if this new model of resource maximization succeeds, it won’...
