...development of the lightbulb sparked the spread of electric power in the U.S. Edison was behind the creation of the first commercial power plant in 1882; New York City had electricity 10 years later. By the late 1930s, the Rural Electrification Administration, one of President Franklin D. Roosevelt's New Deal programs, had delivered electric lighting to nearly every corner of the country. Development on the bulb didn't stop either: researchers have modified Edison and Swan's design further, refining the filament by using tungsten and filling the vacuum with gas, both of which increase the life span...
...surprise that Dyson, the company behind the bagless vacuum cleaner, would devise a bladeless fan. Since the invention of the electric fan in the late 19th century, the air-stirring apparatus has not changed in any significant way - a quick Google Images search suggests that every model from the classic 1950s table fan to the industrial exhaust fan to a Batman-inspired fan has one consistent, characteristic feature: rotating blades. But Dyson did away with those, replacing them with a graceful ring set atop a cylindrical base. In essence, the device works like a vacuum cleaner in reverse. The motor...
Conventional fans, by contrast, are messy, says Andy Samways, senior design engineer at Dyson, explaining the reasoning behind this latest invention. "In a regular fan, the blade is chopping the air up and hurling the packets of air [at you]," he says. The Dyson Air Multiplier bathes users in a constant cool breeze. (See the best inventions...

The rationale behind suspending him and potentially sentencing him to a month and a half in reform school seems highly questionable: Christie is not a student with violent or disruptive tendencies, so the question remains as to which aspects of his behavior need to be “reformed...
