Area codes 614 and 380 are telephone area codes in the North American Numbering Plan (NANP) for all or part of four counties in central Ohio, surrounding and including the state capital of Columbus. Area code 614 is one of the original area codes assigned for Ohio in 1947, while area code 380 is an overlay code covering the same territory.
The first nationwide telephone numbering plan of 1947 divided Ohio into four numbering plan areas (NPAs), one each for a quadrant of the state: 216, 419, 513, and 614. In 1996, 330 and 937 were added by splitting existing NPAs. In 1997, 440 and 740 were added in additional area code splits. In 2000, 234, and in 2002, 567 were added as overlays ...
The faster the relative velocity, the greater the time dilation between them, with time slowing to a stop as one clock approaches the speed of light (299,792,458 m/s). In theory, time dilation would make it possible for passengers in a fast-moving vehicle to advance into the future in a short period of their own time.
1938 – Ives–Stilwell experiment measures time dilation via the relativistic Doppler effect. [35] For the first time, the Lorentz transformations can be derived directly from empirical data, as would be noticed by Robertson in 1949. 1939 – Eugene Wigner rediscovers that SR predicts the Thomas–Wigner rotation.

However, one can often account for most of the discrepancy by the introduction of gravitational time dilation, the slowing down of time near gravitating bodies. In case of the GPS, the receivers are closer to Earth than the satellites, causing the clocks at the altitude of the satellite to be faster by a factor of 5×10 −10 , or about +45.8 ...
Area code 740 was established by an area code split of area code 614 on November 8, 1997. [1] By the end of 2013, exhaust studies indicated that the 740 area code would run out of telephone numbers sometime in 2015. The Public Utilities Commission of Ohio chose a relief plan by implementing an overlay with new area code 220, effective April 22 ...
Area code 847 exhausted its numbers quickly, so that an overlay area code, 224, was implemented in 1996 for relief. However, mandatory ten-digit dialing was not in effect until 2002. In March 2007, an overlay plan was created for NPA 630 adding area code 331, and 779 was added to 815. With the depletion of new numbers in area codes 312 and 773 ...
