Important Days in Mathematics

 1. Euler Day

Every year on 7^th Feb (2/7) is celebrated as Euler day because  Leonhard Euler had calculated the value of e (a constant) to be 2.7182818. The first two number 2/7 is 7^th  February.

2. International Day of Mathematics

UNESCO’s 40th General Conference proclaimed 14 March of every year International Day of Mathematics in November 2019.

3. World Pi Day

March 14 (3/14) is celebrated as Pi Day around the world. U.S. House of Representatives passed legislation to formally recognize Pi Day in 2009 and since then it is celebrated on 14^th March which is also the birthday of Einstein. The idea of celebrating Pi day came in the mind of Physicist Larry Shaw in 1988 but it took 21 years to get the final idea adopted by the world.

4. Women in Mathematics Day

12^th May is celebrated as Women in Mathematics Day around the world. On 31^st July 2018, the Women Committee of Iranian Mathematics Society presented a proposal that Maryam Mirzakhani’s birthday – May 12^th be recognised as Women in Mathematics Day which was approved by World Meeting for Women in Mathematics by a vast majority.

5. Tau Day

Like Pi, Tau is a constant and it is double of pi in approximation. Hence on Every 28^th June (6/28) Tau is celebrated around the world

6. Pi Approximation Day

On 22^nd July, we celebrate Pi Approximation Day (22/7)

7. Math Storytelling Day

Math Storytelling Day is celebrated on 25th September every year. It was created by Maria Droujkova and Sue VanHattum in 2009. This day is celebrated to encourage people to tell stories about Mathematicians, their struggle and contribution and to appreciate the discovery in the mathematics.

8. Fibonacci Day

On 23^rd November (11/23) is celebrated as Fibonacci day because 11 and 23 both are a part of Fibonacci Sequence .

9. National Mathematics Day

Dr Manmohan Singh in 2011 announced that every year 22^nd December should be celebrated as National Mathematics Day because, the child prodigy Srinivasa Ramanujan was born on this day.

10. Pythagorean Day

This day is not celebrated every year but any year where the date, month and year makes a Pythagorean triplet is termed as Pythagorean day. In 2025, 24/7/25 will be Pythagorean Day as – 24² + 7² = 25²

PI APPROXIMATION DAY (22/07) QUIZ

 Dear All

On the occasion of Pi Approximation Day being celebrated on 22nd July (22/7) every year, Here is one very interesting quiz dedicated to Pi. There are 40 questions related 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. 22nd July is the birthday of -- GAUSTAV HERTZ      ---- WILHELM BESSEL  and great Indian mathematician - SHREERAM SHANKAR ABHYANKAR 

3. 22nd July 2024 is the 204th day of the year.  204 is the sum of consecutive primes in two different ways: ---

a) sum of a twin prime (101 + 103) 

b) sum of six consecutive primes (23 + 29 + 31 + 37 + 41 + 43).

204 is the sum of squares of first eight consecutive natural numbers. 

204 = 1²+2²+3²+4²+5²+6²+7²+8².

                                                      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.

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।

त्रिशरादिविषमसंख्यामत्तमृणं स्वं पृथक् क्रमात् कुर्यात् ॥

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.

I hope you have read the information shared here. It is the time to play quiz to explore your knowledge about pi.

International Math Relay Competition

 

1st International Math Relay Competition 

In order to Celebrate Pi Approximation Day, which is celebrated every year on 22nd July (22/7), Competition Baba (A unit of Vishwaroop Foundation, Delhi) is organizing 1st International Math Relay Competition.

In order to get the prizes announced by the Managing Committee of Competition Baba, students have to go through two phases of exam. 

In the first phase there will be a Google Form Based Quiz and the selected students will be playing the Group activity in Mathematics, i.e. Mathematical Relay. 

A team of 3 (either from a school/ member chosen by the Competition Baba team) will play the final round on 22nd July.

1st Round:- A google form Based Test. The syllabus of the test for both Junior and Senior are Class 7 and Class 10 only. Though a balanced question based on 6-8 and 9 -12 has been added so that the students get fair chance to perform. 

Duration :- 60 minutes

2nd Round:- It is a group activities and will be performed by a team consisting of 3 students. A set of 9 questions will be given (3 to each) to be solved in 9 - 15 minutes as decided by the management. Suppose the three boys are P, Q and  R 

a) P will solve his first question and give the solution to Q 

b) Q will solve his question and share the solution of both P and Q to R 

c) R will solve his question, that will require the input value of P and Q

Look at the diagram below to understand the game. Here 1 , 2 and 3 are three students sitting back to back.
