In school we learn there are 360 degrees in a circle, but where did the 360 come from? When it is pointed out that the Babylonians counted to base-60, rather than base-10 as we do, people often ask if there is a connection. The short answer is no. The longer answer involves ...
最流行的猜测是公元前3000年，生活在现在的伊拉克南部的古苏美尔人计算太阳环绕地球的轨迹用了360天完成，所以他们把圆分成360个等份。而这与2000年前生活的同一地区的古巴比伦人不谋而合，他们采用60进制的数学系统。他们应用该系统将角分成60度，6个这样的角组合在一起变成360度，这与古苏美尔人的...
A circle can easily be divided up into six equal parts by marking off points along its circumference at spacings equal to its radius. If each of these parts is taken to be 60 units, then a full circle will be 360 units – which we now call degrees....
Still, my own opinion is that as the sun moves round the earth in 365 days, nearly, the ancient astronomers wished to make the number of degrees in a circle agree as nearly as possible with the number of days in a year.C. WAdams...

was divided into thirty parts,the circular trip around the sky was 12 x 30,or 360 parts long. That is how there came to be 360 degrees in a circle. 1. The purpose of this passage is to explain. A. how the Babylonians measured the time of star movements ...
involves studying circular paths, rather than using meters to describe the angular displacement of an object, physicists use radians or degrees. A radian is convenient because it naturally expresses angles in terms of π, since one complete turn of a circle (360 degrees) equals 2π radians...
by the Akkadians, who then fell to the Amorites, who rose to power and built the nation-state ofBabylon, which peaked in the 18th century B.C. The Babylonians invented the degree and defined a circle as having 360 degrees. There are a couple of theories as to why they chose 360: ...
