Haini Studios presents What is pi? mathematically it is said that pi is a reason, which means that it expresses a relationship in this case the relationship of two measurements of the diameter of the circle with the perimeter How many times does the diameter in the perimeter fit? one two three times and a little more the interesting thing of pi is in that little more no one could calculate with perfect accuracy more than 3800 years ago an Egyptian scribe named Ahmes gave the first approximation of pi when he said The area of a circle is similar to the area of a square whose side is a ninth smaller than the diameter of the circle.
This gave pi a value aproximaded of 3. 16049 and inagurates a mathematical problem that last milleniums the quadrature of the circle the problem is presicely what the value is aproximaded because pi is a irational number, the means that it can´t express with a fraction 22/7ths like an example, it reaches to pi but it isn´t equal from the large of the history ther was some methods to calculate pi Aquímedes found one very ingenious drawing polygons of more and more sides inscribed and circumscribed in a circle and calculating each perimeters, he deduced the value of pi was between 3. 1408 and 3.
1429 Arquidemes reach a poligon of 96 sides but the chinese mathematical Zu Chongzhi use a poligon of 12,288 sides and reached to a presise result, between 3. 1415926 and 3. 1415927 for thousands of years these approximations have been sufficient for most practical applications but idle mathematicians continued to find more and more digits throughout history Newton was shy to pass so much time calculating pi It was between 1671 and 1674 that Europeans Gregory and Leibniz discovered that a mathematician from India Madhava of sangamagrama had invented a method called infinite series which Abraham Sharp calculate 71 digits of pi before the use of the calculators the record of digits was achieved by Daniel Ferguson 620 decimals currently the use of computers and new methods have determined that pi equals 3.
141592653589 and billions of more digites one of the most interesting properties of this numerical constant is that the digit sere seems to be completely random there are no repeated patterns and none digit appears more frequently than another so there are some who think that it has some cosmic significance clear is a transcendent number although that is another mathematical property certainly the Greek name of "pi" did not put the Greeks if not that it was used for the first time in the seventeenth century because with the leter PI starts the word perimeter the popularized Leonhard Euler in the eighteenth century, who like to memorize digits of pi are called piologists Akira Haraguchi has the world record, in 2006 he recite 100 thousand digits and take 16 hours doing pauses to drink water curiosamente if you like our videos support us in pateon. com/curiosamente If you have already subscribed you can click on the bell to receive notifications every time we upload a new video and now im gona try it myself 3. 14159265.
