...thought, "Wow, this is a perfect solution." She had no idea how perfect. Delessert not only knew Piaget but had worked with him. Delessert sent along a photo of the two collaborating on a book, which we couldn't resist reproducing here. You will find other remarkable, often rare photos inside, thanks to picture editor JAY COLTON and assistant JESSICA TARASKI, along with visual treats of all kinds--charts, graphics and even what looks like a subway map. Use it to guide your own journey through the century. We hope you'll enjoy it as much...
When he returned, he noticed a clear halo surrounding the yellow-green growth of a mold that had accidentally contaminated the plate. Unknown to him, a spore of a rare variant called Penicillium notatum had drifted in from a mycology lab one floor below. Luck would have it that Fleming had decided not to store his culture in a warm incubator, and that London was then hit by a cold spell, giving the mold a chance to grow. Later, as the temperature rose, the Staphylococcus bacteria grew like a lawn, covering the entire plate--except for the area surrounding...
Happily, in those days before tape recorders, some of Wittgenstein's disciples took verbatim notes, so we can catch a rare glimpse of two great minds addressing a central problem from opposite points of view: the problem of contradiction in a formal system. For Turing, the problem is a practical one: if you design a bridge using a system that contains a contradiction, "the bridge may fall down." For Wittgenstein, the problem was about the social context in which human beings can be said to "follow the rules" of a mathematical system. What Turing saw, and Wittgenstein...
Until this time, nearly all transistors had utilized germanium because it was easier to prepare in pure form. Silicon offered advantages, at least in theory, mainly because devices made from it could operate at higher temperatures. Also, silicon is a very common chemical element, whereas germanium is relatively rare. Silicon, however, melts at a much higher temperature, making its purification and processing more difficult...
...Goaltending and defense have dominated those earlier contests with the teams skating to a 1-1 tie during the first week of the season. And on Jan. 30, both goaltenders pitched shutouts--extremely rare for a sport in which double-digit goal totals are not uncommon...
