WHY ARE THERE ONLY 60 SECONDS IN A MINUTE?

  In older civilizations, we used numerical systems based on the number 60 (today, it is 10). The most widely used numeral system is decimal (base ten). It is easy for humans to count using their fingers. The civilizations that first divided the day into smaller parts used different numeral systems, specifically duodecimal (base 12) and sexagesimal (base 60). The ancient Babylonians used this counting system based on 60. I think Babylonian scientists and scholars were efficient enough that their contributions still serve us to date. Don't you think so? Babylonian Contributions: The Babylonians were the first to recognize that astronomical phenomena are periodic and to apply mathematics to their predictions. Although it is no longer applicable for general computation, the sexagesimal system, we use it to measure angles, geographic coordinates, and time. Both the circular face of a clock and the sphere of a globe owe their divisions to a 4,000-year-old numeric system of the Babylonia
