Newsgroup: net.math A few weeks ago I sent a proposal to the problem section of Pi Mu Epsilon Journal, which says essentially "Prove that the Cauchy diagonalization process can't prove that the rationals in [0,1] are uncountable". Later I saw a similar problem posted to net.math. I haven't read net news for a while (4-5 weeks) , so it is probable that the net.math problem appeared before I sent my proposal to the PMEJ Problem Editor. I haven't got the courage to do a "readnews -x" to figure out who posted the problem to net.math So if the author felt that for ethical or whatever reason I should withdraw my PMEJ proposal, please tell me so. I am willing to do it any time. ==== Hao-Nhien Qui Vu { alberta, decvax, eagle, harpo, ihnp4, research, sri-unix, ucbvax} !pur-ee!vu or {.................SAME AS ABOVE.........................} !pur-ee!Pucc-K:lcu ***************************************************************************
