That reminds me of a joke... ...but you've probably heard it already, so I will stick to the point. 10^80 + 1 may happen to be a prime number (I leave the proof (or disproof) up to Stephen Paul King as an exercise in applied mathematical reasoning) in which case it is very different from 10^80 in terms of its mathematical properties, even though it is the same when used physically "for all intents and purposes" - since we already know that 10^80 is divisible by 10 (how did I work that, out without even being able to imagine 10^80 objects? It's like magic...! :) -- You received this message because you are subscribed to the Google Groups "Everything List" group.
