thompsons lamp.

i assumed people on sci.math knew about the term.

apparantly i was to optimistic again.

basicly thompsons lamp can be well expressed by ordinary number theory :

lim n -> oo n mod 2 = ???

there is no convergeance , so the answer is not 0 or 1 but ' div ' and in terms of my 3-valued logic :
'0' truth value.

btw all these things have been said a billion times on sci.math , both my own comments and analogues of thompsons lamp.

so i wonder why they are posted again , but i will look at the good side ; this gives me an opportunity to give a good reply and a good reminder of my ideas.

(and btw , yes an AC anomaly)

regards
