Sistema Sexagesimal: Grados

Sexagesimal System: Degrees

Overview

The sexagesimal system, also known as the sexagesimal numeral system or count of 60, is a positional numeral system with a base of 60. The sexagesimal system has roots in the Sumerian and Babylonian civilizations, dating back to around 3500 BC. It was widely used throughout the ancient Near East and Mediterranean regions, particularly in astronomy and mathematics.

Fractional Parts

One unique aspect of the sexagesimal system is that it allows for precise fractional representations without requiring additional symbols or methods for divisions like the decimal system does. For example, the sexagesimal equivalent of the decimal fraction 1/2 is simply 30.

Applications in Astronomy

The sexagesimal system has been used extensively in astronomy due to its multiple divisibility property. It allows for easy calculations involving angles and their subdivisions. The Babylonians utilized this system to track celestial phenomena, such as lunar cycles, planetary movements, and the changing of seasons. Today, we still see traces of this system in our measurement of time, particularly for measuring seconds of arc in celestial navigation and the division of hours into minutes and seconds.

Conclusion

The sexagesimal system has been an integral part of human numerical representation and calculation throughout history. Its unique properties allowed for precise fractional representations and facilitated calculations in fields such as astronomy. Despite the widespread adoption of the decimal system, remnants of the sexagesimal system can still be observed in modern measurements and calculations, particularly in astronomical contexts.
