How Was The Length Of A Second Decided at Abigail Sykes blog

How Was The Length Of A Second Decided. The length of a second was initially determined astronomically, using earth's rotation. It exists only on earth, because it's. A second is really just 1/60th of a minute, which is 1/60th of an hour, which is 1/24th of a day. It might seem obvious at first. It was well known that the period of a pendulum is dictated by its length and that a pendulum exactly 0.994 meters in length would swing once per second. Using this, the length of a second became a sixtieth of a. French scientists found that the proper length depended. It was actually a standard of length: But a problem quickly emerged: We’ve gotten better at pinning down the exact length of a second, but it still has its roots in ancient astronomical. Following the tradition set by the babylonians, these divisions were expressed using the sexagesimal system, a form of counting based on units of 60. The correct length of a seconds. In 1967, the global scientific community agreed to redefine the second according to this number, and the international system of units and measurements now defines a second as the. Just how long is a second?
