The Church-Turing thesis states that every effectively calculable function is a computable function. To put it simply, there is a computer program for every algorithm. %This may seem straightforward now that we have billions of examples useful and working computer programs. @@ -84,8 +84,8 @@ As I still knew little about HCI, I was struck by thunder.
