Metre

In 1983, the fifth legal definition of the metre was the the distance that light travels in a vacuum in 1/299,792,458 of a second. length of the meter was redefined at the 17th meeting of the international body Conférence Générale des Poids et Mesures (GCPM) by a method to give greater accuracy. It superceded the fourth legal definition adopted on 14 Oct 1960 based on a spectral line of kryton. Earlier definitions included the distance between marks on the international prototype metre bar made of platinum-iridium alloy (28 Sep 1889). Before that, the metre was decided that it should be one ten-millionth of the distance from the North Pole to the equator (1 Aug 1793), and the earliest concept was the length of a pendulum with a half-period of one second (8 May 1790).«

A cocky State Highways employe...

A cocky State Highways employee stopped at a farm and talked with an old farmer. He told the farmer, "I need to inspect your farm for a possible new road."
The old farmer said, "OK, but don't go in that field." The Highways employee said, "I have the authority of the State Government to go where I want. See this card? I am allowed to go wherever I wish on farm land."
So the old farmer went about his farm chores.
Later, he heard loud screams and saw the State Highways employee running for the fence and close behind was the farmer's prize bull. The bull was madder than a nest full of hornets and the bull was gaining on the employee at every step!!
The old farmer called out, "Show him your card!!"
