WELCOME TO THE EXCITING WORLD OF MATHEMATICS

Dear Reader, We are well aware of the fact that SQUARING A CIRCLE AND VICE -  VERSA  (using straightedge and compasses only) is impossible because of the trascendency nature of 'pi'  which was proved by German Mathematician Carl Louise Ferdinand Lindemann in 1882. Even after proving this fact, many mathematicians like Jacob de Gelder, Kochansky,  our Indian mathematical legend, Srinivasa Ramanujan who showed his unmatchable ingenuity, tried to construct a square equal in area to the area of the given circle using different rational convergent of 'pi'. They adopted different modes of processes to arrive at the convergent of their choice and their mode provides little chance to reverse the process so that circle can be constructed from the given square. Viewing these deficiencies, KASIRAO. JAGATHAPU, a retired headmaster from V.C.B.R.M.Z.P.   High School, Nellore Dist., A.P. after years of struggle, devised a method not only answering the deficiencies ...

Dear Reader, CRPF Public School, Rohini celebrated Mathematics Week as “Ganit Utsav” from 16 December 2014 to 22 December 2014 to remark the 127 th  Birth Anniversary of the great Indian Mathematician  Srinivasa Ramanujan . The  inauguration  was done by honorable chief guest Anita Sharma Madam, Principal, S.D. Public School, Pitam Pura and respected Principal Sir Sh. H.R. Sharma. A series of interesting events for different classes were organized. On the Inaugural day i.e. 16 December 2014, lecture on Ramanujan and his life was delivered by honorable chief guest Anita Sharma Madam and also by Mr. Amit Bajaj, HOD (Mathematics). Many Mathematical competitions were organized on different days. 1.         POSTER MAKING COMPETITION  FOR CLASSES VI – VIII  (THEME:  MATH’S IN DAILY LIFE) 2.       ORIGAMI   FOR CLASSES III – V 3.        SCREENING OF VIDEOS BY VIG...

Srinivasa Ramanujan (22 December 1887 – 26 April 1920) was an Indian mathematician, who made extraordinary contributions to mathematical analysis, number theory, infinite series, and continued fractions. Ramanujan independently compiled nearly 3900 results (mostly identities and equations). His work continues to inspire mathematicians even today!  Srinivasa Ramanujan, born into a poor Brahmin family at Erode on Dec. 22, 1887, attended school in nearby Kumbakonam. By the time he was 13, he could solve unaided every problem in Loney's Trigonometry, and at 14 he obtained the theorems for the sine and the cosine that had been anticipated by L. Euler. Ramanujan became so absorbed in mathematics that when he entered the local government college in 1904 with a merit scholarship, he neglected his other subjects and lost the scholarship. Ramanujan married in 1909, and while working as a clerk he continued his mathematical investigations. In January 1913 Ramanujan sent some of...

Dear Reader, The Fifth Intra School Mathematics Olympiad was held on 7 November 2014. Hopefully, it was a great learning experience for all. It surely provided an extended platform for all the participating students and it is wished that it is utilized to its fullest. Here are many young   Ramanujan’s   and   Shakuntala Devi’s   in our school who had performed very well in the exam. Check out the result here: V-VIII RANK HOLDERS      V-VIII MERIT HOLDERS IX-XII RANK HOLDERS    IX-XII MERIT HOLDERS   Congratulations to all the rank and merit holders for their brilliant performance in the  Olympiad. You may again like to see the   question papers   and their solutions.

Dear All, Mathematics, often called as language of nature has become an integral part of everyone’s life. In today's highly competitive world, one has to bear a lot of mental stress and also have to get involved in so many things in order to acquire knowledge. This is where co-scholastic activities play a very significant role. They provide the much needed exposure for a student. CRPF Public School has fulfilled its motto of striving towards excellence by organizing and successfully completing its Fifth Intra School Mathematics Olympiad on 7 November 2014. Around 250 students enthusiastically participated in the Olympiad held in school premises. Such Olympiads and events provide a great and extended platform for the students to nurture and showcase their ability and talent. It was a towering learning experience for the students of the school from class VI to XII. To encourage students, merit certificates will be given to those scoring at least 60% along with the normal pr...

Dear Reader, Manjul Bhargava, a Canadian mathematician of Indian origin, has been awarded the prestigious 2014 Fields Medal at the International Mathematical Union’s (IMU) International Congress of Mathematicians held in Seoul. Bhargava, 40, is the first person of Indian origin to receive the prestigious medal, which has been awarded since 1936 and recognizes outstanding mathematical achievement for existing work and the “promise of future achievement”. Known to colleagues as a gifted mathematician who would devise new and simple methods to prove centuries-old theorems in number theory, Bhargava’s work has been described by IMU as based both on a deep understanding of the representations of arithmetic groups and a unique blend of algebraic and analytic expertise. Bhargava was awarded the medal “for developing powerful new methods in geometry of numbers, which he applied to count rings of small rank and to bound the average rank of elliptic curves”, IMU said. One of Bhargava’s mo...

Dear Reader, Well, today is Pi Approximation Day. Pi Approximation Day celebrates the mathematical constant π (pi). It is observed on July 22, due to π being roughly equal to 22/7. The fractional approximation of π ,22⁄7, resembles the date July 22 in the day/month format, where it is written 22/7. Pi Approximation Day is therefore celebrated on July 22. In geometry, pi is defined as the ratio of a circle's circumference to its diameter. July 22, often written as 22/7, is an appropriate day to explore pi, since 22 divided by 7 is an approximation of pi. Pi Approximation Day is celebrated in a number of ways, including contests to memorize pi to the most decimal places, solving math problems involving pi, discovering the history of pi, ruminating on how life would be different without pi and—of course—eating pie. So, enjoy this mathematical day ... Amit Sir

Dear All I am delighted to share with you all that I was invited by Sainik School,Tilaiya , Jharkhand to conduct a three days workshop for teachers from all the 24 Sainik Schools across the country.  In those three days I along with another Math’s expert Mrs. Shuchi Goyal discussed Mathematics beyond Curriculum, Problem Solving, Model Making, and various Hands-on-activities etc. It was really a fun-filled great learning and sharing experience. All the participants enjoyed the sessions and took part in each activity enthusiastically. It is obvious that if teachers of any age or many years experience can enjoy this Mathematics, I am certain the students will also enjoy the same with more zeal and enthusiasm. The only pre-requisite condition is that as a Mathematics teacher we are passionate learner, flexible, ready to change for betterment and have will and desire to do best for the students. It is hoped that all the teachers who attended these sessions are now ready to cr...
