...What the U.S. and China do over the next decade," declared Energy Secretary Steven Chu, the Nobel Prize - winning physicist who is leading President Obama's push for a clean-energy economy, "will determine the fate of the world...
...stuff few of us can understand; he once accidentally discovered an important pulse-propagation effect. But even his most obscure technical work had practical applications; his Nobel-winning breakthrough - supercooling atoms into "optical molasses" - inspired improvements in GPS data and oil exploration. "He's a real-world scientist," says physicist Carl Wieman, who won a separate Nobel using techniques that Chu pioneered. "He's very, very intense, and he's very, very good at solving problems...
...been panned in some circles for her role in coordinating 2002's World Conference Against Racism, otherwise known as the Durban conference in South Africa, which was widely viewed as discriminatory itself. Some of Obama's less controversial choices include the late gay-rights activist Harvey Milk, world-renowned physicist Stephen Hawking, tennis great Billie Jean King, South African Archbishop Desmond Tutu, Senator Ted Kennedy and actor Sidney Poitier...
...question was, How? Simply knowing that the pose works is not the same as knowing why it works - at least, not in the detail a physicist would like. Recently a group of researchers from the Royal Veterinary College in London decided to find out, using tools Edwardian sportsmen couldn't have imagined...
Thilo Pfau, a professor of bioengineering, and his team first outfitted both jockeys and horses with inertial sensors. The humans wore the instruments in their kidney belts; the animals wore them at the front of the saddle. "The sensors are accelerometers similar to what's in the Wii," says physicist Andrew Spence, who participated in the work. "Once you synchronize the two, you can determine the relative motion of the man and the horse." The jockeys also wore global-positioning trackers so their speed and position could be followed. "The tracker was in the helmet, where the GPS satellites could...
