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...
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 ...
one theory links it to the calendrical “circle” of a year. Sumerian mathematicians spotted that the number of days in a year is close to 360, Sumerian mathematicians spotted that the number of days in a year is close to 360, an integer whose prodigious number of factors makes it easy t...
Why is a Circle 360 Degrees, Why Not a Simpler Number, like 100? Hypothesis 1: Mathematical Reasons You may wonder what mathematical reasons there might be for using 360 degrees to represent a complete circle since 360 always seems to cause difficulties in calculating the answers to your math ...
Why is a Circle 360 Degrees, Why Not a Simpler Number, like 100? The Exponential Function An exponential function is a function that assumes the form xª, where x represents a constant, known as the base, and ‘a’, the power of this function, can be any number. Initially, the cons...
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...
A circle is 360 degrees. 7/1000 arcsecond on a circle with a radius of 384,000 km is: 2 * 384,000,000 * π * 7 / 1000 / 3600 / 360 = 13 meters or 42 feet. (π = 3.14) So, even Hubble Space Telescope cannot spot an astronaut on the moon. Its resolution for the Moon ...
