If we are the most important inventions of the last 100 years, very few people think of an atomic clock to. In fact, if you ask to get something with a top ten inventions and innovations, its doubtful that the atomic clock would figure at all.
Its probably not hard to imagine what to think of changing the lives of people as inventions: the Internet, cell phones, satellite navigation systems, media players, etc.
But almost all of thesesTechnologies are based on precise and accurate time and they would not function without them. The atomic clocks located in the heart of many modern innovations, technologies and applications associated with them.
Take the Internet as an example. The Internet is in its simplest form, a global network of computers and this network across time zones and countries. Let us now consider some of the things that we use the Internet for online auctions, online banking or for seat reservationSample. These transactions would not be possible with precise and accurate time and synchronization.
Imagine booking a seat on one airline to 10 and then another customer tried the same seat, after you upgrade a computer book with a slower clock. The computer has only the time to be on the person who After the first few customers, because the clock says, it has been posted check, go! This is the reason any Internet network, which requires time sensitive transactionsis connected to an NTP server to receive and distribute an atomic clock time signal.
And for other technologies in the atomic clock of even greater importance. Satellite Navigation (GPS) is a prime example. GPS (Global Positioning System) works by triangulation atomic clock signals from satellites. Because of the high speed of radio waves, an inaccuracy of 1 second can be Navi device, see the of 100.000 mph.
Other technologies, including those fromMobile air traffic control systems are shown to be completely reliable on atomic clocks, is underestimated, as this technology.
