Dear All
On the occasion of Pi Day being celebrated on 14th March every year, Here is one very interesting quiz dedicated to Pi. The story of pi is more than 4000 years old but the race to find its value is still continued.
Interesting Facts:-
1.
2. Today (14th March) is the birthday of WacLkaw Sierpinski (14/03/1882 - 21/10/1969). According to his wish - the famous Sierpinski Triangle was designed on his grave.
3. The idea to celebrate Pi day came first in the mind of an employee (Mr Larry Shaw) of the San Francisco Science Museum , The Exploratorium in 1988.
A brief Introduction of Pi
Value of Pi = 22/7 is probably taken because Archimedes (born in 287 BC) calculated the ratio of circumference to diameter coming out to be lying between 223/71 and 22/7.
Aryabhata (born in 476AD) was the first Indian mathematician who calculated the value of pi correct up to 4 decimal places. His value of pi was 3.1416.
The Mahabharta decodes the value of pi as 3.

The Moon is handed down by memory to be eleven thousand yojanas in diameter. Its peripheral circle happens to be thirty three thousand yojanas when calculated.
The Sun is eight thousand yojanas and another two thousand yojanas in diameter. From that its peripheral circle comes to be equal to thirty thousand yojanas.
The Bible says -
Also he made a molten sea of ten cubits from brim to brim round in compass and five cubits the height thereof; and a line of thirty cubits and compass it round about. --- Old Testament
William L Schoff says -
Probably no symbol in mathematics has evolved much mystery, romanticism, misconception and human interest as the number of pi.
Buffon
Buffon calculated the value of pi using needle. Ancient Hebrews who built Solomon's temple used pi = 3 while Shatapatha Brahmin calculated the value of pi equals to 3.085.
In 1901, Italian
mathematician Mario Lazzarini Performed the Buffon Needle experiment tossing a
needle 3408 times, he obtained the approximation of pi which was a very
accurate value.
Archimedes in 3rd century inscribed and circumscribed regular polygons up to 96 sides and showed the upper limit is 22/7 and lower limit is 223/71.
Pi Day = March 14 (3/14)
Aryabhata calculated the value of pi correct up to 4 decimal places and can be termed as the first mathematician to do so.
Add 4 to 100, multiply it by 8 and then add 62000. The result is approximately the circumference of a circle of diameter 20000.
Madhava, the founder of Kerala School of Mathematics also calculated the value of pi before James Gregory using the infinite series.
व्यासे वारिधिनिहते रूपहृते व्याससागराभिहते।

यत्संख्ययात्र हरणे कृते निवृत्ता हृतिस्तु जामितया।
तस्या उर्धगताया समसंख्या तद्दालं गुणोऽन्ते स्यात् \\Ramanujan made several attempt and calculated the value of pi through numerous formula.
You can also calculate the value of pi using his formula.
Yale Bablonian Tablet known as YBC 7302 also approximates pi as 3.125 . . .
Interesting Facts About Pi:-
At position 763 which is also known as Feynman Point, there are six nines in a row.
Johann Lambert proved Pi is irrational in 1768.
