...more likely if your room faces south), here are some ways to deal: Keeping your windows closed is an easy and obvious first step. You can also leave your lamp on, which will attract and trap the little pests. If there are just too many, whip out the vacuum cleaner and clean those suckers...
...early as 1820, inventors were homing in on the principles that would lead to the first electric illumination. An English inventor, Joseph Swan, took their early work and developed the basis of the modern electric lightbulb in 1879 - a thin paper or metal filament surrounded by a glass-enclosed vacuum. When electricity runs through the filament, the bulb glows. Edison refined the design, trying filaments made out of platinum and cotton before eventually settling on carbonized bamboo, capable of burning for more than 1,200 hours. With Edison's design - and the settlement of a lawsuit with Swan that resulted...
...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 of a bulb. Still, even modern bulbs are inefficient - less than 6% of the energy used by a bulb goes into producing light. The rest is given off as heat...
...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...
...eastern provinces, attacks inside Pakistan, and more indiscriminate use of air power," Gates wrote in his 1996 autobiography. But it failed to turn the tide. So in February 1988, Gorbachev finally threw in the towel. But at least he could console himself with the belief that the vacuum created by withdrawing would not be filled by Moscow's key adversary. "The U.S.A.," Gorbachev told his Politburo colleagues, "is not going to send in its armed forces if we leave...
