The Chinese government has been making bold announcements about the future of its space program — space stations, Mars rovers, Moon landings, the whole shebang. And in addition to being of note space-wise, the country’s plans have some pretty interesting political implications.
To Build evokes IBM Watson’s ability to extract implicit connections from explicit concepts within text, revealing the fundamental building blocks of cognitive technologies – their ability to think like humans.
Molecular architects: how scientists design new materials
by Gregory McColm
When Thomas Edison wanted a filament for his light bulb, he scoured the globe collecting thousands of candidates before settling on bamboo. (It was years before people were able to make tungsten work properly.) That’s our traditional way of getting materials. We picked up stones for axes, chopped wood for housing and carved tools out of bone.
Then we learned to synthesize new materials out of old ones, like shaping clay into bricks or pots and baking them into stone. Plastics entered our repertoire as a concoction of cotton, acid and wood tar.
Much of the quest for novel materials has moved into science labs. The search is more efficient than when Albertus Magnus (allegedly) synthesized the Philosopher’s Stone, but the game is still intelligent serendipity. We try combinations of ingredients, combinations of heating, mixing and other processes, and hope that one of them works. During the last few decades, a scaled-up, highly organized and automated search system called “combinatorial chemistry” has produced new drugs and materials including automotive coatings, hydrogen storage materials, materials for solar cells, metal alloys and organic dyes.
Architects and engineers do not wait on search or serendipity to produce a novel bridge that doesn’t collapse under a 10-ton truck. They use established principles, paper and pencil (and software) to produce a design that they can confirm, by computation and deduction, will meet the necessary specifications. Today’s chemists and materials scientists are taking a similar approach, pushing forward a materials revolution.
Finding a quality home cinema with decent features and fine performance at a reasonable price on the growing projector market may not be as easy as it may seem at first sight. But you need not worry, because we’ve done the work for you – and we proudly present to you Epson PowerLite Home Cinema 2000, one of the two home entertainment projectors recently introduced by the famous producer of electronic imaging and information equipment.
Technology was soon introduced to the wizarding world after the second wizarding war. The next generation grew with the knowledge of many muggle objects such as a ‘cellular phone’ or the ‘television set’. They weren’t more familiar with these concepts than their magical equivalents, but these objects weren’t alien to them either.
