...painting with a little something wrong about the mouth!" In 1907, at the age of only 51, Sargent decided to give up doing "paughtraits," as he disparagingly called them--except for those commissions he couldn't refuse, like a 1917 portrait of John D. Rockefeller. Sargent wanted to travel more and do landscapes, especially in watercolor--and next only to Winslow Homer, he was the finest American watercolorist of his time...
That's an immense if. Drexler's idea was initially dismissed as science fiction, but even skeptics admit that, unlike time travel and warp drives, nothing about it actually violates the laws of physics. And when in 1989 an IBM team famously spelled the Big Blue logo in xenon atoms, nanotech spread from the basements of feverish acolytes poring over Drexler's seminal book, Engines of Creation (1986), to the research labs of NASA and Xerox PARC. Today nanotech researchers speak not of if but of when. Great leaps forward come from thinking outside the box. Drexler may be remembered...
...long before, Goddard, a physics professor at Clark University in Worcester, Mass., had published an arid little paper on an outrageous topic, rocket travel. Unlike most of his colleagues, Goddard believed rocketry was a viable technology, and his paper, primly titled "A Method of Reaching Extreme Altitudes," was designed to prove it. For the lay reader, there wasn't much in the writing to excite interest, but at the end, the buttoned-up professor unbuttoned a bit. If you used his technology to build a rocket big enough, he argued, and if you primed it with fuel that was powerful...
Goddard meant his moon musings to be innocent enough, but when the Times saw them, it pounced. As anyone knew, the paper explained with an editorial eye roll, space travel was impossible, since without atmosphere to push against, a rocket could not move so much as an inch. Professor Goddard, it was clear, lacked "the knowledge ladled out daily in high schools...
...start of the century to dream of filling the skies with airplanes and the roads with cars. It was another thing to figure out how to keep all that traffic straight. The solution turned out to be radar, an application of electromagnetic radiation that forever changed the nature of travel, warfare and even space exploration...
