You can’t make a call or send a text on your mobile phone in the US town of Green Bank, West Virginia. Wireless Internet is outlawed, as is Bluetooth. As you approach the tiny town on a two-lane road that snakes through the mountains, your mobile phone signal drops out, and your radio stops working. The rusted pay phone on the north side of town is the only way for a visitor to reach the rest of the world. It’s a pre-modern place by design, lacking of the latest technologies that define life today.
The reason for the town’s empty airwaves is apparent the moment you arrive. It’s the Robert C. Byrd telescope, also known as the GBT, a shiny white, 147-metre-tall satellite dish. It’s the largest of its kind in the world and one of nine in Green Bank, all of them government owned and operated by the National Radio Astronomy Observatory (NRAO).
You don’t look through these kinds of telescopes. They’re radio telescopes, so instead of looking for distant stars, they listen for them. There’s a long line of astronomers all over the world who want to use the telescope which is so sensitive that it could hear a single snowflake hitting the ground 1,000 miles away.
Such a sensitive listening tool needs total technological silence to operate, so in 1958 the US government created a National Radio Quiet Zone, a 33,000 km2 area covering Green Bank where, to this day, electronic and radio signals are forbidden every hour of every day.
People who live within a 15km of the Green Bank telescope are allowed to use landline telephones, wired Internet and cable televisions, but microwave ovens, wireless Internet and radios are forbidden. You can have a mobile phone, but you won’t get a signal.
Because of how much its way of life varies from the rest of America, Green Bank seems to be a somewhat isolated (隔绝), even alien place. For locals, the technology ban is annoying. For others who come to Green Bank for a little rest and relaxation, the town has become a refuge.

when. “We’ve learned that what really affects people is their sense of how they’re doing compared with other people in their peer group, or with where they thought they would be at a certain point in life, says Brian Kropp, who heads CEB’s HR practice. “We’ve learned to focus on moments that allow people to make these comparisons.”
