Am I in Pi? Checking 1254543 digits of I found starting at this location in PI: This document will tell you where in PI your birthday first occurs..

E.G., If you were born Feb 20th 1969 search for: 22069 No spaces... (you can also search for 2201969, but, that is less likely...) For those that dont remember, PI is the big(*) number that begins with three. Thanks to Arthur Bebak (arthur@msm.com) for the idea... * It has been brought to my attention that PI is not really all that "big", per se -- 4 being given as an example of a number bigger than PI.

By Maria Popova From Copernicus to Ancient Korea, or what the Chinese concept of change has to do with Aztec astrology.

The love of maps is a running theme here at Brain Pickings, from these 7 must-read books on creative cartography to, most recently, BBC’s fantastic documentary on important medieval maps. Humanity’s long history of visual sensemaking is as much a source of timeless inspiration as a living record of how our collective understanding of the universe and our place in it evolved. It seems like the farther from the known mapmakers’ imaginations traveled, the more fascinating their maps became. And hardly does the unknown glimmer with more alluring sparkle than the cosmos. The Emperor's Astronomy Petrus Apianus. Development of Mathematics in Ancient China. Development of Mathematics in Ancient China Chinese Math Texts The history of Chinese math and mathematicians was mostly lost or destroyed over the centuries.

For example, the despotic emperor Shih Huang-ti of the Ch'in dynasty (221-207 B.C.) ordered the burning of books in 213 B.C. Scholars in the following Han period (206 B.C. to 220 A.D.) had to transcribe China's literary and scientifice traditions from memory or remaining fragments of scroll. Knowledge of astronomy and other areas was often handed down from father to son, and only later recorded in texts. Since the 16 century, Chinese math history has also been denied and ignored in the Western dominance of science and technology, both inside and outside China.

However, there are several existing Chinese applied mathematics texts, which are collections of problems and solutions organized in chapters according to their practical applications. 50 Interesting Facts about Pi.

Cyclotomic method: Liu Hui used the area of n-gon inscribed in a circle (with n being the larger the better) to estimate the area of a circle.

In his own word, he said that “The finer the circle being cut, the smaller error we get when we estimate; if we continue to cut until the polygon can’t be cut any more, then the area of this polygon yields the area of the circle”. It is worth noticing that his method coincides with the modern infinite series methodology of estimation. Basically, his theory is to say that : When n goes to infinity, n-gon is congruent to circle.

Objective To duplicate the method Archimedes used to estimate the value of pi. copy of the "Archimedes' Recipe for Pi" student handout (PDF or HTML)paperpencilcompassrulercalculator Tell students that they will be exploring Archimedes' method for estimating the value of pi, a mathematical constant that is the ratio of a circle's circumference (the distance around a circle) to its diameter (the distance across a circle through its center).

The Greek symbol for pi is pi. Organize students into groups. Provide copies of the "Archimedes' Recipe for Pi" student handout and other materials to each group. If students need guidance, you may want to clarify the following concepts: For any circle, if you divide the circle's circumference by the diameter you will always get the same number, pi.
