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...
Another theory that suggests why a full circle is 360 degrees comes from the Babylonians. The Sumerians and Babylonians famously used theSexagesimalnumber system. The sexagesimal system is one with a base value of 60, while the current system we use is known as the decimal system and has...

If you go all the way around a circle, in other words, 360 degrees, the number of radius lengths you’ve gone around the circumference is equal to 2?. I always found this to be extremely confusing. Why was one circle equal to 2?? Why is a half a circle ?, and why is a quarter...
