A couple more things from last night. In 1942, silver was available when copper was in short supply so $1,000,000,000, in 1942's terms, was used to build a centrifuge. They went to some effort to retrieve every scrap afterwards; detail is on Wikipedia. "How much do you need?" I replied, "Six thousand tons." 'How many troy ounces is that?" he asked. — https://en.wikipedia.org/wiki/Calutron#Construction Ivan Sutherland's 1988 Turing-Award paper on `Micropipelines' used for asynchronous linkage of blocks in a circuit instead of a synchronous clock. https://dl.acm.org/citation.cfm?id=63532 Free PDF download.
