Science != technology. Today primary school pupils know about the equivalence of matter end energy. Secondary school pupil/student [may] know about critical masses for nuclear reactions. Better yet, some of this information is written in [more or less] scientific encyclopedias (/me having read those and other data at about 9/10). Obscurantism is NO solution. Talebans anyone? "Dangerous" technologies, that is, the precise details of how to _work_ eg plutonium to make a bomb out of it, *should* be kept secret. Alas, this is not always possible, but they should. > The way we control such things is to control the availability > of the critical raw materials very, very carefully.

I had left out one of the most important details. --Salvo To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-chat" in the body of the message
