#### Transcript of Mesopotamia: Maths and Measurement

MESOPOTAMIA:
MATHS and MEASUREMENT Here are some quick facts about the Mesopotamian uses of Math and Measurement: 1. Mesopotamians had a base 60 numeral system. Sixty is a superior highly composite number, as is 12. That means those numbers have a great amount of factors. Because of this system, we use base 60 for our modern time measurements. 60 seconds to a minute, 60 minutes to an hour. 12 is also a superior highly composite number. 12 months in a year. 2. People in Mesopotamia had very different systems of measurement then we did. Silver scraps replaced barley as a system of money, and weight. They also used a theoretical cube of water called the Royal Gur-Cube. The gur-cube was about 6m x 6m x 0.5m. It was a unit of measure from which all units could be made. 3. The Mesopotamians invented our modern lunar calender. Then, the year had only 360 days, because 360 was a number considered to have magical properties. They divided the 360 days into 12 lunar months of about 30 days each. The actual lunar months are 29 and a half days. The seven day week is also based on the phases of the moon. 4. The Mesopotamains were the first to do a lot things. They were the first to recognize the concept of 0, and model rates(exponential growth). Archaeologists have found clay tablets with quadratic and cubic equations, fractions, and the Pythagorean Theorem. Mesopotamia developed astronomy, mathematics, logarithms, and exponential values. Ancient and Modern examples of the Pythagorean Theorem A weird fact: The oldest calender was found in Iraq. It's 10,000 years old and is a pebble with 12 notches around it. They were also first to give numbers place value! Here is an example of the way Mesopotamians wrote their numbers: Mesopotamian Mathematics are often referred to as Babylonian Mathematics. Babylonians measured the circumference of a circle as 3 times the diameter and the area as 1/12 the square of the circumference, which would be correct if pi is estimated as 3. Modern mathematicians have proved pi to be about 3.14. Babylonian mathematics are important because
they have helped us to develop the mathematics
we use today. They also discovered many theories
and methods that we still use. Without math, a functioning society with a trade system could never have been built. Mesopotamians were the first to use math, in measuring, time, mass, capacity, and area, and gave us the lunar calender we use in modern day. Math helps us everyday. Without the Mesopotamians building a number system, and discovering everything we use in math today, we would never have come this far in mathematics and measurment. Here's a short video about place value to the millions. We included this video because Mesopotamians were the first to give numbers place value. THE END!! (hope you enjoyed!) By: Emily Clark, Blair Zemanek, Carrie Nielsen. Div. 7-4 Here's a video about Pi! Mesopotamians were the first people to use different ways of measuring area, length and width. They also measured the volume of things and how much different things weighed. They had 12 main systems to measure things, and here are a few:
GAN2 System G used to count field measurement
ŠE system Š used to count barley by volume
ŠE system Š' used to count malt by volume
ŠE system Š" used to count wheat by volume
ŠE System Š* used to barley groats
EN System E used to count weight
U4 System U used to count calendrics
DUGb System Db used to count milk by volume
DUGc System Db used to count beer by volume
These systems were used in everyday Mesopotamian life, but we don't use them in the present time because we now have other ways of measuring things.
