Drafted by James Madison, and presented by Edmund Randolph to the Constitutional Convention on May 29, 1787, the Virginia Plan proposed a strong central government composed of three branches: legislative, executive, and judicial. On May 29, 1787, Virginia delegate Edmund Randolph proposed what became known as The Virginia Plan.. Written primarily by fellow Virginian James Madison, the plan traced the broad outlines of what would become the U.S. Constitution: a national government consisting of three branches with checks and balances to prevent the abuse of power.
The Struve Geodetic Arc is a chain of survey triangulations stretching from Hammerfest in Norway to the Black Sea, through ten countries and over 2,820 km, which yielded the first accurate measurement of a meridian.he new flattening estimate was one part in 298.257 222 101 and the equatorial radius was 6,378,136.8 metres. An earlier survey, in 1740, had given flattening at one part in 178 and an equatorial radius of 6,396,800 metres.
The radian is the SI unit for measuring angles, and is the standard unit of angular measure used in many areas of mathematics. The length of an arc of a unit circle is numerically equal to the measurement in radians of the angle that it subtends; one radian is just under 57.3 degrees. The unit was formerly an SI supplementary unit, but this category was abolished in 1995 and the radian is now considered an SI derived unit. Separately, the SI unit of solid angle measurement is the steradian. The
