360 වුණේ ඇයි???

[lpwicrama]

ඒක එහෙම තමා ආය මොකටද කොහොමද කතා වැඩක් නෑ කියල තමා අපිට කියල තියෙන්නෙ ​

We use 360, because it has a lot of divisors: 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360. Each of these numbers is a different way that we can cut up the circle in an exact way. If you have nine people, and you want to cut a pizza, then you need to cut each slice at 40 degrees. This makes computation easy.

වැඩිම කොටස් ගණනකට බෙදිය හැකි අඩුම සංක්‍යාව 360

උදා රවුමකට අනසක 360 නොවී 100 අනසක කියලා තිබුනනං ඒක 60 කට බෙදන්න වුනාම ගැටළුවක්

ඒ නිසා 1, 2, 3, 4, 5, 6, 8, 9, 10, 12, 15, 18, 20, 24, 30, 36, 40, 45, 60, 72, 90, 120, 180, 360 වගේ කොටස් ගොඩකට බෙදිය හැකි ගණනක් යොදාගෙන තියෙන්නේ

The Sumerians watched the Sun, Moon, and the five visible planets (Mercury, Venus, Mars, Jupiter, and Saturn), primarily for omens. They did not try to understand the motions physically. They did, however, notice the circular track of the Sun's annual path across the sky and knew that it took about 360 days to complete one year's circuit. Consequently, they divided the circular path into 360 degrees to track each day's passage of the Sun's whole journey. This probably happened about 2400 BC.

That's how we got a 360 degree circle. Around 1500 BC, Egyptians divided the day into 24 hours, though the hours varied with the seasons originally. Greek astronomers made the hours equal. About 300 to 100 BC, the Babylonians subdivided the hour into base-60 fractions: 60 minutes in an hour and 60 seconds in a minute. The base 60 of their number system lives on in our time and angle divisions.

An 100-degree circle makes sense for base 10 people like ourselves. But the base-60 Babylonians came up with 360 degrees and we cling to their ways-4,400 years later.


In 1936, a tablet was excavated some 200 miles from Babylon. Here one should make the interjection that the Sumerians were first to make one of man's greatest inventions, namely, writing; through written communication, knowledge could be passed from one person to others, and from one generation to the next and future ones. They impressed their cuneiform (wedge-shaped) script on soft clay tablets with a stylus, and the tablets were then hardened in the sun. The mentioned tablet, whose translation was partially published only in 1950, is devoted to various geometrical figures, and states that the ratio of the perimeter of a regular hexagon to the circumference of the circumscribed circle equals a number which in modern notation is given by 5760+366025760+36602 (the Babylonians used the sexagesimal system, i.e., their base was 60 rather than 10).

The Babylonians knew, of course, that the perimeter of a hexagon is exactly equal to six times the radius of the circumscribed circle, in fact that was evidently the reason why they chose to divide the circle into 360 degrees (and we are still burdened with that figure to this day). The tablet, therefore, gives ... π=258=3.125π=258=3.125.

Another motivation for choosing the number 360 may have been that it is readily divisible: 360 has 24 divisors,[note 1] making it one of only 7 numbers such that no number less than twice as much has more divisors (sequence A072938 in the OEIS).[12][13] Furthermore, it is divisible by every number from 1 to 10 except 7.[note 2] This property has many useful applications, such as dividing the world into 24 time zones, each of which is nominally 15° of longitude, to correlate with the established 24-hour day convention.

අද මම උඹලගෙන් පොඩි ප්‍රශ්ණයක් අහන්නම්..
අපි හැමෝම දන්නවනේ ලක්ෂයක් වටා කෝණයේ අගය අංශක වලින් 360ක් කියල. පුළුවන්නම් දන්න එකෙක් කියපල්ල ඇයි ලක්ෂයක් වටා කෝණය අංශක 360 කියල කියන්නෙ???
දන්න එවුන් උත්තරේ ගහගෙන යන අතරෙ නොදන්න එවුන් බම්ප් කරන් පලයල්ල හොඳේ...

A good question.

හොඳ ප්‍රශ්නයක්, හේතුව ඉස්සර හිටපු මිනිස්සු අපිට වඩා බුද්දිමත්, අපේකාලෙ උන්නම් කරන්නෙ 100 ට හරි 1000 ට හරි බෙදන එකනෙ,

ඒත් ඉස්සර මිනිස්සු භාවිතාකරෙ 12 පාදයේ සංඛ්‍යා,
උදාහරනෙකට ගත්තොත්,

දවසට පැය 24
විනාඩියට තත්පර 60,
අඩියට අඟල් 12
දුසිම,
ඔරලෝසුවෙ අංක 12

අපිට ඇඟිලි 12 ක් තිබ්බනම්, ලෝකෙ මීට වඩා ගොඩාක් වෙනස්, එහෙනම් අපි අදටත් භාවිතා කරන්නෙ 12 පාදයේ සංඛ්‍යා,
