WORLD PI DAY (14th March 2026) QUIZ
Dear All
On the occasion of World Pi Day being celebrated on 14th March (3/14 in American Date style) every year since 1988 when it was first celebrated by Larry Shaw, an employee of a science museum in San Francisco, the Exploratorium.
(Taken From Internet)
Pi Day was particularly momentous in 2015, when the numerical date corresponded with π up to five digits: 3.1415.
Here is one very interesting quiz dedicated to Pi. Let's know the mysterious number pi.
Don't forget to share with your known/students/teachers/
Just give a TRY
The story of pi is more than 4000 years old but the race to find its value is still continued.
Interesting Facts:-
1. 
(Courtesy:- From the Tweet of @Cliff Pickover)2. 14th March 1879 is the birthday of Albert Einstein whereas Stephan Hawking died on 14th March 2018. It is interestingly the birthday of WacLlaw Sierpinski who is known for Sierpinski triangle and square.
Sierpinski Triangle and Sierpinski Square
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.
योजनानां सहस्राणि विष्कम्भो द्वादशास्य वै ॥ 6-12-40
परिणाहेन षट्त्रिंशद्विपुलत्वेन चानघ ।
षष्टिमाहुः शतान्यस्य बुधाः पौराणिकास्तथा ॥ 6-12-41
चन्द्रमास्तु सहस्राणि राजन्नेकादश स्मृतः ।
विष्कम्भेण कुरुश्रेष्ठ त्रयस्त्रिंशत्तु मण्डलम् ॥ 6-12-42
एकोनषष्टिविष्कम्भं शीतरश्मेर्महात्मनः ॥ 6-12-43
सूर्यस्त्वष्टौ सहस्राणि द्वे चान्ये कुरुनन्दन।
विष्कम्भेण ततो राजन्मण्डलं त्रिंशता समम् ॥ 6-12-44
अष्टपञ्चाशतं राजन्विपुलत्वेन चानघ।
श्रूयते परमोदारः पतगोऽसौ विभावसुः ॥ 6-12-45
एतत्प्रमाणमर्कस्य निर्दिष्टमिह भारत ।
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.
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।
त्रिशरादिविषमसंख्यामत्तमृणं स्वं पृथक् क्रमात् कुर्यात् |
यत्संख्ययात्र हरणे कृते निवृत्ता हृतिस्तु जामितया।
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 . . .
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.
On 30th anniversary of Pi, Google had made a beautful doodle on Pi that shows the relation between circrumference and diameter.
I hope you have read the information shared here. It is the time to play quiz to explore your knowledge about pi.
A certificate is attached with the quiz provided you score 75% marks so try your luck and win certificate.

NATIONAL MATHEMATICS DAY QUIZ
Srinivasa Ramanujan (22 Dec 1887- 26 April 1920) , FRS was an Indian mathematician whose mammoth work in mathematics has created history. On 22nd December, every year we celebrate the NATIONAL MATHEMATICS DAY to commemorate his birthday.
The young generation should make him an ideal, who fought against all odd but never let his first love mathematics go from his mind. Despite having no food to eat both time regularly, not enough money to buy good books, he defeated every odds with his strong determination and became one of the favourite student of Prof G H Hardy.
He struggled to pass his FA twice, left his home, did odd job of tuition and finally got a job of clerk at Madras Port Trust before moving to England in 1914.
During his stay at England, he was of poor health but that didn't hinder his progress. He together with Hardy wrote 50 research paper and got an FRS degree.
His notebook containing 3400 theorems were proved by Bruce Berndt.
Ramanujan's birthday is celebrated as National Maths Day in India since 2011.
J B S Haldane once said -- If Ramanujan's work had been recognized in India as early as it was in England, he might not have emigrated and might have been alive today.
Here is a 250 marks quiz that shows you many picture related to Ramanujan and will help you to know Ramanujan in a better way.
