Who calculated the value of pi first?
The value of pi was first calculated by Budhayana, and he explained the concept of what is now known as the Pythagorean Theorem. British scholars have (1999) officially published that Budhayan's works dates to the 6th Century, which is long before the European mathematicians. |
Did Bhaskar II discover calculus?
Bhaskar II was born in Vijapur in the province of Karnataka in 1114 A.D. He wrote Siddhanta-Shiromani in 1150, which became a classical text in Mathematics and Astronomy. The book is divided in four parts: Lilavati deals with arithmetic, Bijaganita with algebra, Ganitadhyaya and Goladhyaya with astronomy. In Siddhanta Shiromani, Bhaskar II defines two kinds of planetary velocities: Sthula gati (average speed) and Sukshma or Tatkaliki gati (instantaneous velocity). The process of finding instantaneous velocity involves the use of differential calculus. There is definite proof that Bhaskar II carried out such calculations using the method of differentiation. According to Hindu astronomy, l = lmean ± r sina/R where, l = true longitude lmean = mean longitude r = radius of the epicycle a = anomaly and, R = radius of the deferent cycle Bhaskar II formulates the expression for the tatkaliki gati (instantaneous velocity) as follows: "To find the instantaneous velocity (in longitude) of the planet, the kotiphala is to be multiplied by the time rate of change of anomaly and divided by the radius, and the quotient (thus obtained) is to be added to or subtracted from the velocity of the mean planet according as its position is in the six signs from the beginning of Cancer or Capricorn." Expressed mathematically, dl/dt = dlmean/dt ± (r cosa/R) da/dt where, r cosa = kotiphala This equation not only provides his familiarity with the notion of differentiation, but also shows his knowledge of the expression d(sina)/da = cosa After Bhaskar II, India went through a long hostile foreign rule, and could not produce any mathematician of his caliber for a long time to come.

And finally Ramanujan Srinivasa developped the quadratic equation which now permit to the computer to calculate pi with billions of decimals....
http://ic.net/~jnbohr/java/formula.gif http://numbers.computation.free.fr/C...ramanujan.html http://en.wikipedia.org/wiki/Srinivasa_Ramanujan Tribute to this genious mathematician. His works began only be studied and understood. Ramanujan left a book which contain many formulas witout proofs, he was a real genious. P.S: Ramanujan found many different formules to calculate Pi. |

You are saying they used π since 800 BC in India and I don't deny that! I only say that pi is not the invention by Indians first when it is known to Agyptians in 1700 BC already. You must know that 1700 BC is 900 years earlier than 800 BC! Or do you want to deny it? ... It's not a logical thinking ...
Who said you that Indian Civilisation didn't exist before 1700 B.C ?? Harrapa and Indus Valley cities were said to be the one of the most anciant cities until that they discoverd the Dwarka underwater city in Gujarat which is estimitated to 7500 B.C , do you know that my srilankan bro ? It is not myth but reality. |
Friends,
Mathematics and its origins are from India, Bible has quiet a lot of Maths wrongly. And friend says- Ramanujam developed it because he went Abroad. I have put the article from Wikipedia- in Indian Heritage page NO-13, which acknoledges it. Bill Gates, when asked if Indian were not allowed to work in his Company. in USA, he would move to India. So Foriegners have the skill to develop it and market commercially, but the basic is from India. uppuma |

It is not myth but reality. My srlinkan bro, what is not a logical thinking? I said that the egyptians had the knowledge of pi = 3.16... arrounf 1700 BC. It is found on papyrus of that time. This also means that they had already invented writing too. The matter about pi the vedic moron SRS is talking about is from 800 BC. This Indian pi =3,003 was also not that "accurtae" as of that egyptian. This only shows that i) Indians were late in "inventing" pi (later than the Egyptians) ii) Indians were not accurate with the pi (than the Egyptians) iii) Indians invented their own pi Bearing the knowledge about pi has nothing to do with a society that can be called a civilisation, my dear srilankan bro! |
"Bearing the knowledge about pi has nothing to do with a society that can be called a civilisation, my dear srilankan bro!"
What I tried to say is that a civilisation should forcebily know Pi...Otherwise we cannot talk about civilisation... Pi is not an "invention"... Nobody can invent Pi, because Pi already exists, and can't be invented... Pi number is more a conception than an invention..

Friends, have a look at the following site :
VEDIC MATHEMATICS NEWSLETTER ISSUE No. 23 Vedic Mathematics is becoming increasingly popular as more and more people are introduced to the beautifully unified and easy Vedic methods. The purpose of this Newsletter is to provide information about developments in education and research and books, articles, courses, talks etc., and also to bring together those working with Vedic Mathematics. If you are working with Vedic Mathematics - teaching it or doing research - please contact us and let us include you and some description of your work in the Newsletter. Perhaps you would like to submit an article for inclusion in a later issue or tell us about a course or talk you will be giving or have given. If you are learning Vedic Maths, let us know how you are getting on and what you think of this system. ***************************** This issue’s article is taken from a longer article by Andrew Nicholas. The full article can be viewed at www.vmacademy.com INDIA’S SYSTEM OF MENTAL MATHEMATICS THE VEDIC IDEAL In the vedic system, the work is done mentally. This stems from the tradition being an oral one. In practice, today, the initial problem or question is usually written down and the answer or solution also. The work being done mentally, a one-line answer results. This is the vedic ideal. BACKGROUND But what is this word ‘vedic’? It refers to an ancient period in India’s history. Tradition has it that the system of the vedas covered all branches of knowledge. Originally an oral tradition, it began to be written down around 1600 or 1700BC, according to western scholars. Over the next thousand years four vedas, as they were called, were recorded - rig-veda, yajur-veda, sama-veda and atharva-veda. An appendix to this last contained a section headed ‘Ganita Sutras’, i.e. mathematical formulae, or principles. In the nineteenth century scholars began to look at it, but could make no sense of what they found there: statements such as, ‘In the reign of King Kamsa, famine, pestilence, and insanitary conditions prevailed.’ Then a brilliant south Indian scholar, Shri Bharati Krishna Tirthaji (1884-1960), began a detailed investigation. He concluded that the above statement about King Kamsa was a cryptic form of the decimal fraction for 1/17, using letters to represent single-digit numbers, much as we might use the letter A to represent 1, and B to represent 2, etc. Having obtained one clue, further investigation led him to conclude that the whole of mathematics is based on 16 sutras, and he finally wrote 16 volumes on the topic. Then events intervened. He was virtually forced into becoming a Shankaracharya. Hindu India has four of these top religious leaders - a bit like having four Popes. The upshot was that he left his beloved vedic mathematics alone for many years. Returning to the subject in the 1950‘s, it emerged that the 16 volumes had been lost. On realising this, he decided to re-write them all, and began by writing a book intended to introduce the whole series. Ill health stopped him from getting any further, and he died in 1960. This introductory book is now all that we have by him. It was first published in 1965. DIFFERENT IDEAS ABOUT NUMBER Western version When measuring weight, the bigger the number, the greater the weight. Similarly for temperature, length, electric current etc. We are used to the idea that larger numbers are weightier. Vedic version In the vedic system, numbers are viewed differently. An analogy is telephone numbers, which we don’t associate with quantity. They are patterns of digits acting as addresses. Similarly, when working to a base of ten (as we normally do), the vedic system deals with the single-digit numbers 1, 2, 3, 4, up to 9, together with the zero, arranged in different patterns. For example, we don’t divide by 52, we divide by 5, and take account of the 2 afterwards. This shift of focus eliminates the heaviness, or weight, associated with the common view of numbers. The vedic mathematician considers a number such as 52 as 5 and 2 in succession. IS VEDIC MATHEMATICS CURRENTLY USED IN INDIA? CAN YOU TELL US ABOUT DEVELOPMENTS THERE? To answer the first question first, yes and no. It is used there to some extent. Here is a brief account of the developments. Tirthaji died in 1960 ‘Vedic Mathematics’ was published in 1965 Before going to India in 1981 I wrote to all Indian universities to find out what more was known about the subject. About 30% of them replied. No one could tell me anything more about it. Evidently the subject was being neglected. However, one or two letters pointed me to Tirthaji’s last residence and ashram in Nagpur. Visiting there, I was invited to return the following year to teach a fortnight’s course. These days, the subject can be taught in schools, alongside the conventional system. Where this is done, I am told, the pupils have no problem with learning the two approaches side-by-side - the western and the vedic. There is also a passionate debate raging about the status of Tirthaji’s system. Some argue that it is historically accurate, despite the lack of normal historical evidence. Others argue that, lacking evidence for its historical validity, it should be dismissed - despite the fact that, mathematically, it works. My view (which I am not alone in holding) is that it is a reconstruction. At present we are unable to say for sure that it is historically accurate - nor to prove that it is not. This is because we are dealing with an oral tradition, and it is no surprise that written evidence may not be available. WHAT IS THE POTENTIAL OF THE SYSTEM? Tirthaji points out that it normally takes about 16 years to go from first steps in mathematics to a Degree in the subject. (e.g. from age 5 to age 21). But he states that with the vedic system the course in its entirety could be done in about two years! Of course, at present we don’t have all the material that’s needed available. Needless to say, however, this would benefit everybody - not least those who are not interested in mathematics and would prefer to spend less time on it! I think, myself, that once vedic mathematics begins to win general acceptance it will lead people to question other academic disciplines. Are rapid methods available in other subjects? If so, are they being used, and if not can they be developed? **************************** NEWS **************************** New course in london Following the successful recent course at Imperial College another introductory course is to take place at the Regency Hotel, Queen’s Gate, London, SW7 5AG, on five Mondays from 29th April 2002. Time: 7.00 to 8.30 pm. Course fee: 30 pounds (20 pounds, students and concessions). Enquiries: tel. 020 8688 2642. Topics covered: Squares and Cubes, pi and the Vedic numeral code, Easy Calculus, Fibonacci within Nature, Mathematics and Mind. BUSINESS APPLICATION OF A VM SUTRA “Business India” has published an interesting article by Chetan Dalal entitled “Practical application of Vedic mathematics – Vedic mathematics has certain visual solutions which could be applied in problem solving”. This is on the application of Anurupye Shunyam Anayat (zero value of one of the variables in Simultaneous equations where the other variables are in perfect proportion to constants) illustrated in an Insurance claim. The article ends: “This illustration . . . emphasizes on the simplicity of the tenets of the sutras of vedic mathematics. Perhaps research and intensive study of vedic scriptures might reveal even more advanced applications. What is illustrated above is a very elementary application of the sutra. The depth and richness of the vedic knowledge is beyond description. Greater research and more teamwork in sharing of ideas and interpretation may provide revolutionary results.” It would be good to see more such applications of the Vedic Sutras. MULTIPLICATION ON THE FINGERTIPS A lot of interest was taken in the article in the last newsletter. Mr. Carlos Javier Maya from Mexico has given an idea for doing multiplications of 2 digit by 2 digit on the hands when the multiplier is 19. Mrs Sharma is developing the methods further and is currently conducting a series of courses on Vedic Mathematics. Dr Abhijit Das in Mumbai, India, has also been researching this area, but without using fingers. We hope to have an article by him for the next newsletter. COSMIC CALCULATOR COURSE NOW AVAILABLE As stated in the last newsletter this Vedic Maths course, that covers the National Curriculum for England and Wales, can now be obtained. In India you can purchase whatever you need from Motilal Banarsidass shops and presumably from other bookshops.

P. Jain at mlbd@vsnl.com **************************** CORRESPONDENCE Email: First of all I am thankful to those who are behind this effort of rejuvenating vedic science or mathematics. I have learned very few mathema-tactics when I was giving some scholarship exams in 4 th standard. These were taught to me by my Nanny at that time. I could score 99/100 in that exam. and much of it due to use of vedic maths. But afterwards I never pursued it. I have done engineering and after so much of years have passed now I have decided to study vedic maths from scratch. I have done tutorials from your site and they are simply best to add my interest. So please subscribe me as student and pls. guide me what next I should do. **************************** Your comments about this Newsletter are invited.

But for what purpose did a civilisation need pi if not for wheel making first? With the knowledge of pottery the mankind aquired the next knowledge called the wheel. With the aquiring of wheel knowledge they had the need to know about pi. Do you want to say that Inkas, Mayas and Aztekes are not civilisations? They did not know about wheels! Quote:

This discussion only started because I denied the SRS' claim that the Indians aquired the knowledge of pi up to 32 digits ca. 800 BC which is definitely not true! I would suggest you, my dear srilankan bro, try to understand first before you start to think! What you read and how you read is not important but the understanding. Only then you'll gain logical thinking before you assess me illogical. |

By the way, I am of the opinion that the "wheel" was "invented" without any knowledge of pi. A rolling wheel simply represents one type of motion. People must have observed rolling objects and then concieved of a wheel. The dimensions of the circular wheel need not necessarily have been calculated using pi, especially considering that pi is an irrational number - the concern was only with constructing a functional wheel and not the abstract properties of a perfect circle.

unlike you I spent a bit time in decoding the pi-mantra you have provided and located some errors there. So I analyzed your decoding table and coloured the mismatch. Can you clarify the mismatch to the hubbers? Will you ever refrain from copy and paste, you clown? AS I have to assume that your vedic brain does not understand the mismatch, I better explain further: According to you ka can be 0 and 1 ta can be 1 and 6 tha can be 2 and 7 da can be 3 and 8 sa can be 5, 6, and 7 Why can't you apply all numbers to all consonants and say PaPa x MaMa is Star! ==> 00x00=*! ==> 0 (read Zero) No one wonders why you were not educated in India. Anyway, copy and paste you have learned very well but nothing else! |

I say that the english one is from tamil onRu-onnu-oNdu! What do you vedics say now? ?
The German numbers: eins, zwei, drei, vier, fünf, sechs, sieben, acht, neun, zehn Deutsch - Tamil eins - ains zwei (sometimes zwo) - tsvai (tsvo) drei - dhRai vier - (f)viar fünf - (f)vyun(f)v sechs - seks sieben - sIpen acht - akd neun - noyn zehn - sEn 11 - elf - el(f)v 12 - zwölf - tsvel(f)v So the english numbers are more germanic than of any other. For example take the "shit" (cit -in tamil) - the scots say shite (cait - in tamil) and the germans say Scheiße (caise - in tamil) Further England comes from Angelland which is german meanig the land for angling. And the germans spoke of Angelsachsen (angelsaksen in tamil) which only means the angling Saxons. Saxons are one of the german tribes like the Bavarians, Prussians, Swabians. English is also very near to Low German that is still spoken by some of the north costal Germans. |
