X-Message-Number: 11002 From: Date: Thu, 31 Dec 1998 09:42:53 EST Subject: cracking etc Keith Dugue (#11000) asks how brain cracking can be avoided, in view of the fact that different parts of the brain presumably have different coefficients of thermal expansion. First, as previously noted, actual experiments with CI procedures on sheep heads and cat heads, involving slow cooling, show no visible cracking on either a micro or macro scale. (See our web site for detailed reports.) Explanation? My guess is that any differences in coefficient of expansion are not sufficient, or not sufficiently abrupt, to produce a noticeable cracking. As for the 21CM methods and results, we are waiting for useful information, and will make these methods--or anyone's--available to CI members either as standard procedure or as special options, at the appropriate time and price. And the usual reminder: Those who defer a commitment, while waiting for the situation to be clarified or improved, may die while waiting. If you make a choice and a commitment now, you can always change later, if you so decide, at no great cost. If you fail to commit now, you may never get the chance--either because you die first, or you lose your insurability, or you lose your competence, etc. Just about every week or two we get the too-late phone call and the sad refrain: "If only (I, we, he, she) had acted sooner!"
