The Intriguing Origins of 60 Seconds in a Minute and 60 Minutes in an Hour
Written on
Chapter 1: The Historical Context
Have you ever pondered the reason behind having 60 seconds in a minute and 60 minutes in an hour? Many people overlook this, as it has been the norm for thousands of years. Remarkably, the structuring of our timekeeping system began nearly 4,000 years ago. The ancient Sumerians and Babylonians established a system based on intervals of sixty, which has persisted through the ages. The Babylonians were already codifying their astronomical observations around the 14th century BCE, approximately 3,400 years ago, and it is from these early calculations that we derive some of our fundamental units of measurement.
The Sumerians introduced a base sixty numbering system known as the sexagesimal system. While we currently utilize a base ten system, which relies on intervals of ten, the sexagesimal system offered several advantages that we may overlook today.
Section 1.1: Advantages of the Sexagesimal System
The number sixty stands out as the smallest integer that can be evenly divided by the first six counting numbers (1 through 6). Additionally, it is divisible by 10, 12, 15, 20, and 30, making it exceptionally convenient for division. With eleven straightforward divisors, splitting sixty into manageable groups becomes remarkably easy.
This method of division is mirrored in our timekeeping practices, demonstrating the adaptability of a base sixty system. Since sixty is so user-friendly, we can conveniently divide hours into quarters (15 minutes), halves (30 minutes), and even intervals of six (10 minutes). Such common time divisions are still prevalent in our daily lives, where phrases like “I’ll be there in ten minutes” or “half an hour” echo the practices of ancient Sumerians.
Subsection 1.1.1: Timekeeping Challenges with Base Ten
If we had adopted a base ten system for hours, achieving simple quarter-hour intervals would be cumbersome, as a quarter of ten results in 2.5, complicating our timekeeping.
Chapter 2: The Legacy of the Sexagesimal System
The influence of the sexagesimal system extends beyond mere timekeeping. The Babylonians were pioneering inventors and mathematicians, being the first to divide a year into 360 days (which is sixty multiplied by six) and to define a circle as having 360 degrees. While the calendar was later adjusted to reflect the actual astronomical year of 365.25 days, their original approximation was not far from the truth.
The first video titled "Why Are There 60 Seconds in a Minute? - Ancient Sumeria" explores the fascinating historical context of our timekeeping practices, tracing their roots back to ancient civilizations.
The second video, "Why are there 60 seconds in a minute?" delves into the significance of the number sixty in our daily lives and its lasting impact on modern society.
Section 2.1: The Complexity of Ancient Numbering Systems
The use of a sexagesimal system complicates the interpretation of numerology, proportions, and religious calculations. When analyzing ancient structures, discrepancies can arise due to the different numbering systems employed by their creators. For instance, some theorists have purportedly identified patterns related to the speed of light in ancient ruins, but without understanding the underlying base of the numbering system, such comparisons can be misleading.
So, the next time you check the time, remember the Babylonians, who laid the groundwork for our clocks. The remnants of the ancient sexagesimal system are woven into various aspects of our lives, often without our awareness. While the base ten system is efficient, particularly in the context of the metric system, the sexagesimal system retains its value, which explains its enduring presence today.
