Aryabhatta the Indian mathematician

Aryabhatta, also known as Aryabhatta I or Aryabhata (476-550?), was a famous Indian mathematician and astronomer, born in a place called Taregana, in Bihar (though some people do not agree with the evidence). Taregana (also spelled as Taragna) which literally means songs of stars in Bihari, is a small place situated nearly 30 km from Patna, which was then known as Kusumpura later Pataliputra, the capital of the Gupta Empire. This is the very empire that has been dubbed as the “golden period in Indian history”. The best introduction to the genius of past is seen in the words of Bhaskara I who said, “Aryabhatta is the master who, after reaching the furthest shores and plumbing the inmost depths of the sea of ultimate knowledge of mathematics, kinematics and spherics, handed over the three sciences to the learned world”.

What was his name?

Varahamihira, the younger contemporary of Aryabhatta also mentions him as “Aryabhata”. In addition to this, Bhaskara I too mentions him as Aryabhata. It seems as if the correct name was Aryabhata and not Aryabhatta. This could mean that “Bhatta” was not his surname but as part of his first name. In fact, there is a lot of confusion about his name too. Perhaps he was called Arya and his surname was Bhat or Bhatta!

Where did Aryabhatta come from?

There is some disagreement about this birth place. Some are of the view that he was born in Patliputra while some are of the view that he was born in Kerala and moved to Patliputra and lived there. Those who say that he was in Bihar is because of this name. His name “Arya” and “Bhatta” indicates that he was from North India. His suffix “Bhatta” could have been either part of his name or his surname, till date it’s not known if this is correct or not. It is interesting to note that Aryabhatta himself have mentioned himself at only 3 places and as “Aryabhata” in his work Aryabhatiya.

The reason for not considering Kerala as his birthplace is that nowhere in his works he has mentioned Kerala. In addition, all works of Aryabhatta is in Sanskrit and Sanskrit was not used in Kerala. So to claim that Aryabhatiya was written in Kerala has no credibility. Furthermore, he has been identified by numerous mathematicians and in Arabic translations as someone who hailed from Kusumpura (modern Patna), the capital of Magadha. It therefore appears that Aryabhatta was born, lived, flourished and worked in Magadha. He has also been described as the head of the Nalanda University.

Influence of Aryabhatta on science and mathematics

Aryabhatta is considered to be one of the mathematicians who changed the course of mathematics and astronomy to a great extent. He is known to have considerable influence on Arabic science world too, where he is referred to as Arjehir. His notable contributions to the world of science and mathematics includes the theory that the earth rotates on its axis, explanations of the solar and lunar eclipses, solving of quadratic equations, place value system with zero, and approximation of pie (π).

Aryabhatta exerted influence on the Indian astronomical tradition to such an extent that his presence was felt in neighboring countries and cultures also. There have been various translations of his work among which the Arabic translation during the 820CE is very significant.

When mathematical students are confused with trigonometry even today, Aryabhatta had defined sine, cosine, versine and inverse sine back in his era, influencing the birth of trigonometry. The signs were originally known as jya, kojya, utkrama-jya and otkram jya. In Arabic they were translated as jiba and kojiba, which later when being translated into Latin was misunderstood to be ‘fold in a garment’ by Gerard of Cremona, who stated it as sinus, which meant fold in Latin. Aryabhatta was the first mathematician to detail both sine and versine (1 − cos x) tables, in 3.75° intervals from 0° to 90°, to 4 decimal places.

Aryabhatta’s astronomical calculations influenced the Arabians, who used the trigonometric tables to compute many astronomical tables. His calendared calculation has been in continuous use in India, on which the present day Panchangam is based. His studies are also base for the national calendars of Iran and Afghanistan today.

The Story of Numbers (0 and 1) Indian Numerals or Arabic?


It is known that Aryabhatta has authored at least three astronomical books, in addition he also wrote some free stanzas. Among them “Aryabhatiya” is the only text that has survived to this day, whereas unfortunately his other works have been extinct. It is a small treatise written is 118 verses, which summarizes the Hindu mathematics of that time. This great mathematical masterpiece of the past starts with 10 verse introduction, which is then followed by mathematical section which is written in 33 verses that gives out 66 mathematical rules, but there is no proof to go with it. The mathematical part of the Aryabhatiya is about algebra, arithmetic, plane trigonometry and spherical trigonometry in addition to advanced mathematics on continued fractions, quadratic equations, sums of power series and a table of sines.

The next section consists of 25 verses which gives us glimpse into the planetary models. The final section of the book is dedicated to sphere and eclipses which runs into 50 verses. He states that the moon and planets shine by reflected sunlight. Instead of the prevailing cosmogony where eclipses were believed to be caused by pseudo-planetary nodes Rahu and Ketu, he explains eclipses in terms of shadows cast by earth or those shadows that fall on earth. It is amazing how Aryabhatta could explain both lunar and solar eclipse so accurately.

There is some argument over the claim of Aryabhatta being the inventor of place value system that made use of zero. Georges Ifrah, in his work ‘Universal history of numbers: From prehistory to the invention of the computer (London, 1998)’ writes in work, “ is extremely likely that Aryabhatta knew the sign for zero and the numerals of the place value system”. Georges Ifrah has studied the works of Aryabhatta and found that the counting and mathematical work carried out by him would have been not possible without zero or place value system.

Honouring Aryabhatta

The Indian ISRO (Indian Space Research Organization) named its first satellite after the genius mathematician and astronomer. A research establishment has been set up in Nainital, called the Aryabhatta Research Institute of Observational Sciences (ARIOS) to honor his contribution to the field of science. There is also a lunar crater and a species of bacteria discovered by ISRO named after Aryabhatta.

Some of the works of Aryabhatta include

  • Aryabhatta worked out the value of pi.
  • He worked out the area of a triangle. His exact words were, “ribhujasya phalashariram samadalakoti bhujardhasamvargah” which translates “for a triangle, the result of a perpendicular with the half side is the area”.
  • He discussed the idea of sin.
  • He worked on the summation of series of squares and cubes (square-root and cube-root).
  • He talks about the “rule of three” which is to find the value of x when three numbers a, b and c is given.
  • Aryabhatta calculates the volume of a sphere.
  • Aryabhatta described the model of the solar system, where the sun and moon are each carried by epicycles that in turn revolve around the Earth. He also talks about the number of rotations of the earth, describes that the earth rotating on its axis, the order of the planets in terms of distance from earth.
  • Aryabhatta describes the solar and lunar eclipses scientifically.
  • Aryabhatta describes that the moon and planets shine by light reflected from the sun.
  • Aryabhatta calculated the sidereal rotation which is the rotation of the earth with respect to the stars as 23 hours, 56 minutes and 4.1 seconds.
  • He calculated the length of the sidereal year as 365 days, 6 hours, 12 minutes and 30 seconds. The actual value shows that his calculations was an error of 3 minutes and 20 seconds over a year.

Although we know nothing about the personal history of Aryabhatta, he was the genius who continues to baffle mathematicians even to this day.

  1. Hello Shalu,

    Such an emotion evoking post. Aryabhatta is immortal with his greatest service to the world through this contributions to the field of mathematics.Without him there would not have been geniuses like Srinivas Ramanujan in this field today who took over from where he left. My gratitude to you for this post.

    Thanks and Regards,

  2. Your post is very informative about the great man “Aryabhatta”.
    he is the inventor of zero,he find out the place value system Ana many more.he is great mathematician and astronomy also.his main article’s name is aryabhatttiya.

    he give many solution about summation of series of squares and cubes.many discoveries are there which me made own…………..

    • Bhusan, there seems to be some confusion as to who invented zero. Some are of the view that Aryabhatta knew how to use the zero while Brahmaguptra another of India’s great mathematicians (lived around 600AD) could have invented the zero. Nonetheless both knew and applied zero and this was in India.

  3. Shalu Sharma,

    A very informative post. May I ask a simple doubt to you. You mention in your post about ‘Hindu mathematics’. Hindu is a religious group, it has a racist discriminative background of dividing Indian society into different racial groups, the Brahmins being placed on top. Only they were supposed to learn at the expense of the others especially of the lowest varna they had decreed. I do not believe in their decree, for I do believe that knowledge cannot be constructed by a people who do not live in nature and in connection with other people. Brahmins are a people stayed aloof from the rest of the people stuck to their arm chair. If you look into the philosophy of knowledge construction you will know this, without being practical you cannot construct knowledge. I am talking about fundamental knowledge in maths. Knowledge construction in traditional India was very much related to problem-solving that is solving problem faced with, say in agriculture, building etc. Those were jobs done by the labour class. varna Hindu considered labour as anathema.

    Now Aryabhata was a great Indian mathematician, but in his statue I see a thread across his chest the poonool an essential varna mark of a Brahmin. So was he a Brahmin? If so was it not possible that he got the knowledge from other people? My logic makes me think like that.

    In other words, I think it more appropriate to write Indian mathematics rather than Hindu mathematics, because that usage can give rise to these kinds of doubts. Do not worry I am a Hindu.

    Please, what do you think about this. 🙂

    • Prasanna Raghavan,

      This is a very good question.

      I think the terminology “Hindu Mathematics” is very appropriate. Mind you, Aryabhatta’s date of birth is the same as the prophet in Arabia. While they were still fighting amongst the tribes, we Indians were looking at the sky and making astrological advances. If there is any country that made similar progress, it was the Greeks. The Arabs later too became advanced in Mathematics and adopted many of Hindu mathematics and promoted it in the name of Islamic mathematics. Hence the use of Hindu mathematics and not Indian is appropriate. I believe that the use of “Hindu” does not divide India into racial groups. Racial and religious differences are two different things. For instance, my Muslim neighbour who speaks Hindi with me is racially the same as me.

      As far as Aryabhatta’s origins is concerned, there is a lot of confusion. He lived in Patliputra (modern Patna) the capital of the Gupta Dynasty (golden period of India) and was the head of the maths department at Nalanda as written by another mathematician called Brahmagupta. Many historians claim he was from Bihar and some say he was from Kerala, whatever it may be, and he lived in Bihar where he taught mathematics.

      Now, he could have been a Bihari or a Keralite. My feeling is that he was a Bihari and a Brahmin at the same time. His name Arya Bhatt is a typical north Indian name. Part of his name “Bhatta”, is a Brahmin name in many parts of Bihar, Uttar Pradesh and so on. Hence he could well have been a Brahmin. Considering that most of the recitation of the Sanskrit scriptures was done by Brahmins, while Pali remained the language of the poor, it is probable that he was a Brahmin. If we go by name, another famous mathematician Brahmagupta could well be a Bania caste as Gupta is a typical Bania name.

      These are my thoughts, please feel free to expand and explore.

      • Dear Prasanna Raghavan,
        Your concept of Hinduism is based on western thoughts it seems. The chaturvarnya system was evolved some 5000 years back, for welfare of society of that period. Even now all are not considered equal that is why entrance exams for medical, Engg. or IAS is done. Based on needs of that time such a system would have naturally evolved. But later on like any other system ( see the condition of our democracy even in modern times!) that system also got polluted by selfish people and led to degradation to some groups. What would have been our fate if people like Aryabhatta would have been sent to paddy fields as part of socialism? so in those times intelligent people were given adequate support by rulers and such unparallel outcome resulted, which could not be expected in this so called moders golden era of nepotism, partiality etc. shown by many rulers in the name of democracy and secularism…

    • All great Intellectuals have been aristrocats in the past,well mostly. You are right knowledge cannot be gained just by sitting in the armchair but privilege and class does not exclude you from seeking knowledge. A greedy trader can get a steady supply of provocative ideas and problems while he lords over the toiling laborers. A Brahmin can have outstanding knowledge of human society even if he has himself divided it and placed himself on the top. The greatest writers in human history who have written with compassion and deep insight about the toiling masses have been mostly kind of people who have interacted with the lower classes but have themselves been born in the upper class. Your basic logic that knowledge you have to know the real world to gain knowledge is correct. But the ideological inference is very false. Abstract Knowledge is on such area where you require minimal influence from outside world. And as much as you need it you easily gain from your everyday life. like it is not that a rich man cannot ‘feel’ what goes inside a poor man’s head. To say that will be absurd. And it is called Hindu Science or whatever because a persons identity was more dependent on the social group in the past then a nation. And different civilizations in past lived in relative isolation so there is such a thing called Hindu Civilization even.

  4. I really proud to be Indian.
    I am from Math background and I can easily say that work and inventions done by Aryabhatta in the field of Mathematics are priceless.
    It takes ages to do a single invention and he has done several inventions in single life.
    Thanks Shalu ji for sharing another Historical episode of Indian Pride with us.

  5. Great post Shalu. It was a chance to open the treasure of influential people of India. I knew little about our renowned and one of the earliest mathematician Aryabhatta but here you have provided all the information about him. Feel proud to be an Indian at the moment.

  6. Hello,

    We work in french education and I am interested in your article because I do not personally know this person. On our Pinterest page, we offer to our readers, teaching notes on various subjects, including mathematics. I would add Aryabhatta, one of these formulas or one of these quotes, but I can not find quotes from him. Do you have one of his words ?

    Thanking you for your contribution.

  7. Sorry, I’ve not given the link :


    French quotes

    • Hello Marie,
      Aryabhatta was a great personality who was the first to calculate Pi. His books were mainly Aryabhatiya that covers arithmetic, algebra, plane trigonometry and spherical trigonometry. The book is in Sanskrit which you need to find a translation. For instance one of his quotations was

      …ribhujasya phalashariram samadalakoti bhujardhasamvargah…
      that translates to
      ..”for a triangle, the result of a perpendicular with the half-side is the area…”

      another one

      caturadhikam śatamaṣṭaguṇam dvāṣaṣṭistathā sahasrāṇām
      ayutadvayaviṣkambhasyāsanno vṛttapariṇāhaḥ.

      This shows that the ratio of the circumference to the diameter is ((4 + 100) × 8 + 62000)/20000 = 62832/20000 = 3.1416
      This is value of pi accurate to 5 significant figures.

  8. I never knew about Aryabhatta and his contributions in math. Glad to have read about him here in your post. Thanks for sharing, Shalu!

  9. There is a lot of confusion about the invention of zero. The west likes to lay claim to everything that is not theirs. Aryabhatta certainly knew about the use of zero and used in this calculations.

    Aryabhata stated that “sthanat sthanam dasaguņam syat” which means, “place to place in ten times in value”, ie “from place to place each is ten times the preceding” which is the origin of the modern decimal-based place value notation.

    There is no doubt that the concept of zero has been attributed to India but who exactly is difficult to interpret.Brahmagupta is another candidate who has shown many theories and he has documented the use of zero in his works.

  10. Great post Shalu, Proud to be an Indian. We have many great legends like Swami Vivekananda, Gandhi ji, Rani Lakshmibai and much much more. The list can’t even be covered at one shot. Thanks for sharing this awesome post.

  11. This Article is wonderful. Aryabhatta’s inventions happened when hardly any other scientific information were available. The world should rise above religion and country to show Gratitude to this great personality.

  12. hi shalu…
    As i am Indian i liked most of your post on this blog which are really symbolizing Indian culture…. this is really passion towards Indian culture… it is just mind blowing…..

  13. Aryabhatta (476-550 A.D.) was born in Patliputra in Magadha, modern Patna in Bihar. Many are of the view that he was born in the south of India especially Kerala and lived in Magadha at the time of the Gupta rulers; time which is known as the golden age of India. There is no evidence that he was born outside Patliputra and traveled to Magadha, the centre of education and learning for his studies where he even set up a coaching centre. His first name “Arya” is hardly a south Indian name while “Bhatt” (or Bhatta) is a typical north Indian name even found today specially among the “Bania” (or trader) community.

  14. I personally believe that dividing between race is not a good idea,Aryabhatta was from the children of Adam as we are,and same goes to every man living on this planet…

  15. Hello Shalu,

    It’s interesting to note that Aryabhatta contributed to the value of pi. Indians are excellent engineers and where a superb technological inventions is, for sure there is a good Indian somewhere around.

    Based on your post it seems he combined his faith with science, which often results into something outstanding.

    • Jena, I also think that Aryabhatta was an outstanding mathematician of this times. One interesting and fascinating thing about him is that he also used “zero” in this calculations but he did not document it hence he has not been attributed to finding zero.

  16. I could not find Aryabata’s Sanskrit verse in Devanagari script, though it is available in Malayalam script.
    The Sloka is: (In English letters)
    Caturadhikam śatamaṣṭaguṇam dvāṣaṣṭistathā sahasrāṇām
    ayutadvayaviṣkambhasyāsanno vṛttapariṇāhaḥ.
    Can somebody provide it in Devanagari?

  17. Thanks for posting this wonderful article.
    But wikipedia says that he was born in Kerala, India.

    Sadly we don’t have a proper history or it was destroyed over the years.

  18. dear shalu,
    arya is a south indian name..!! well priests in vaysnava i.e., Iyengars(brahmin) worshiper of lord vishnu is called as bhattar ..! i think he is south indian Iyengar brahmin..!! where last name might be an suffix..!!! and had a good read.! being civilized first why we(indians) are still struggling to become greatest nation in the world..! we should be in the position where america is now..!! 🙂

    • Hello Radhakrishnan, I think that Arya is a North Indian name. History tells us that Aryans came from Central Asia who settled along the Indus Valley and while their residents where slowly pushed downwards towards the South. Hence Arya was also always associated with the North as compared to the Dradian south. Correct me if I wrong.

      • Great post Shalu.I agree with you AryaBhatta is most likely to be a North Indian and likely Bihari. Arya is used by North Indians. And Bhatt is used mostly by North Indian Brahmins. Brahmagupta is likely to be a Bania. These two were along with modern day Ramanuja the greatest mathematicians India has produced.Like you said Gupta is a North Bania surname. And he was born in Rajasthan. And Rajasthan is known to have given birth to themost famous Banias-Marwaris. Also I think Gupta Empire was Bania. What do you think of Mayrya Empire? I have read many theories regarding this.He has been described as Kshatriya and it is said he may be illegitimate son of Nanda from some Dasi in his court. He may have been a Brahmin but this evidence is very thin. He may have been a Bania because he Ashoka married a Bania tribe princess. What you make of it?

      • You cannot conclude that he is from Bihar just going by the name “Arya”. Arya can be found in many South Indian names and was used in olden times to denote Bhramin names. A famous example is Adi Shankara whose birthplace is recorded as Kaladi in Kerala who was also known as Shankaracharya.

        Aryabhata provides no information about his place of birth. The only information comes from Bhāskara I, who describes Aryabhata as āśmakīya, “one belonging to the aśmaka country.” During the Buddha’s time, a branch of the Aśmaka people settled in the region between the Narmada and Godavari rivers in central India; Aryabhata is believed to have been born there.
        It has been claimed that the aśmaka (Sanskrit for “stone”) where Aryabhata originated may be the present day Kodungallur which was the historical capital city of Thiruvanchikkulam of ancient Kerala. This is based on the belief that Koṭuṅṅallūr was earlier known as Koṭum-Kal-l-ūr (“city of hard stones”); however, old records show that the city was actually Koṭum-kol-ūr (“city of strict governance”). Similarly, the fact that several commentaries on the Aryabhatiya have come from Kerala has been used to suggest that it was Aryabhata’s main place of life and activity.
        It is fairly certain that, at some point, he went to Kusumapura for advanced studies and lived there for some time. Both Hindu and Buddhist tradition, as well as Bhāskara I (CE 629), identify Kusumapura as Pāṭaliputra, modern Patna. So while he lived in Bihar, it is not correct to conclude its his place of origin based on name alone.

          • Aryabhata has never provided any information anywhere about his place of birth. The only thing one can deduce from his writings is that he was born in 476CE. That he was born in Kusumapura, etc are conjectures arrived at by people just because he lived and worked there as well as from his name. He could have very well migrated there from elsewhere due to the presence of the University and the astronomical observatory there just as anyone today would looking for career and growth opportunities. Also Bhaskara-I mentions him as belonging to the Asmaka people who are known to have settled in Central India during his time.
            There is no logical/ rational basis or historical or documented information to conclude that he belonged to either Kerala or Bihar.

          • I don’t see any logic in the following argument from the post
            “In addition, all works of Aryabhatta is in Sanskrit and Sanskrit was not used in Kerala. So to claim that Aryabhatiya was written in Kerala has no credibility.”

            Where is Adishankara from? All his works are in Sanskrit!!!

          • How many Keralites do you know who can speak and write Sanskrit? In Bihar, you will find many. Also Aryabhatta has himself identified himself from Kumsumpura today’s Patna. There is no dispute about his origins. He was NOT from Kerala!

  19. Aryabhatta born in Kerala, India in 2700 BC, was the first to calculate Pi of 3.1416 and the solar year of 365.358 days . He propounded a heliocentric universe 4200 years before Copernicus, with elliptically orbiting planets and a spherical earth spinning on its axis explaining the motion of the heavens. He was the father of plane / spherical Trigonometry and Algebra, when Europe was in the dark ages.. Today you don’t see this pioneers name in the list of top 100 mathematicians.
    Aryabhatta was the first to compute the circumference of the earth, with an error of just 64 miles.. Aryabhatta gave a method to find the cube root of numbers and dealt with arithmetic,geometric and indeterminate equations in algebra. He dealt with square, cube, triangle, trapezium, circle and sphere in geometry. He was called Arjehir by the Arabs.
    Poor Galileo copied Aryabhatta 4 millennium years later , that the earth is round and circles the sun , and the church blinded him , so that he can never look into another telescope .

    Typical of the west to steal and propagate it as their own, like everything else. Give credit where credit is due, this is plagiarism of the worst type. India has been the center of spiritual & scientific discovery thousands of years before western copy cats claimed it as their own and wrote the history books.

    Today as the world celebrates Copernicus 540th birthday and hails him as the discoverer of heliocentric theory, i wanted to comment on greatness of India and its people and how much we should be proud of our history and not be divided by cultural or geographic divide. The ocean of knowledge is never empty.

    Jai Hind

    • Aryabhatta was born around 450 A.D. Around 1000 years prior to Copernicus and not 4000 as you claim! Also his place of birth is disputed but most likely he was born in present day Bihar,Bhatta is a North Indian Brahmin last name. And while his place of bith is uncertain,most likely it was Bihar and not Kerala. And in any case he lived and taught in present day Bihar. You are right though India used to be a great nation and is generally not given enough credit by the west. West usually gives more credit to intellectual dead woods like Arabs and our simple northern neighbors(China)

      • @Gaurav You are missing the point here, its not about when he was born, its about what he did and its important that it resonates across as a important contribution. No need to muddy the water on mere birth dates..

        • You criticize me on a point I never made or intended. Sure his contributions are more important. But still it was important to correct your erroneous assertion. The majority opinion is Aryabhatta was born in Bihar. Some place his birth in Maharastra, some in Kerala. And in my personal opinion Bihar or some other North Indian state looks more likely given his very North Indian name.
          Anycase larger point is he was Indian and is not given due credit by the west. West often gives huge credit to Chinese and Arabs when they simply borrowed from Hindus. Buddhism is of course Indian, so is Taoism and most Chinese philosophy- ultimately drawn from India. Arab numerals, most astronomy, mathematics, science is drawn from India or Greece. Chinese are the only major civilized nation that never came up with the concept of a supreme God! All they did was reach up to the level of ancestral spirits.

        • Muddying the water on birth dates? An error of 3,000 years is important! It puts his achievements in context. Or if you are so disinterested in dates why is it important to know about past historical figures like Aryabhatta at all? World has moved on, you can simply pick up a Mathematics textbook of your choice in the local supermarket.

          • Gaurav, just in the same way we are interested in what Aryabhatta did, it is also important where he came from. India is a divided society and we take pride in our caste, region and language. It would be nice to know where exactly he was born be it Bihar or Kerala. My feeling is that he was from Bihar given his name.

          • @Gurav didn’t mean to start a riot on the dates and semantics, that was not the intention, the point i am trying to make is on discoveries made by Indian & eastern minds, years earlier, and flagged off as made by western modern science. The aim i am taking at is how laughable it is that the west has for so long patented, copied & rewarded ( for ex. setting up ‘Noble award’ like bodies) themselves for scientific discoveries that should be fairly attributed to and acknowledged as having roots in India.

        • Harsh, I agree with you on this point. Aryabhatta may have come from anywhere. But the fact is that he lived in Kumsumpura (current Patna) and he was the head of Astronomy and Maths at the Nalanda University. Main thing is what he did not not where he was born.

  20. Hey Shalu
    Thanks for sharing this post about Great indian mathematician Arya bhatta. He is one of my favourite mathematician and I really likes his concepts of trigonometry. You really described well about this mathematician so thanks once again. 😉

  21. No doubt the Indian culture is one of the richest in the world. Her hundreds of unknown cases in Western society, demonstrating the enormous potential of this region appear. Participate and share the best apps on your PC with BlueStacks.

  22. The best and most elaborate account of Aryabhatta that I ever came across. I look forward to buying your books for my 10-year old daughter. Shalu, you are a blessing; may your tribe increase

  23. Dear Shalu Sharma,
    Many thanks for the interesting post. Thediscussions and disputes about his place of birth appears to be misplaced. We all should be proud that he is an Indian and gave a lot to the world of Astronomy and Mathematics. We should rather rejoice and celebrate this instead !

    I am keen to know his actual date of birth. Can anyone throw some light on this ?

  24. Superb”on work of place value he intriduced number system to the world in5’th cent. I proud be indian and bihari

  25. Great post. I was just wondering what credible sources might have been used to gather all this information? I would be interested in reading more about how things are documented from history and books etc. Would you be able to site references?

  26. Nice post.Aryabhatta is an mathematician who belongs to india and he is the person who introduced the zero.And he also inventend may equations in maths.Thanks for shallu for wriiting good blog.I am great fan of him.

  27. nice nice and nice posts every person who have interest or any other person who dont have must read this page . Its very knowlegable page

  28. Dear Shalu Sharma

  29. Aryabhat inventend zero and today whole math is working on that basis. They were great and here you posted a great and brief information about them that is really appreciable and for this a salute for you.

  30. Great article of Aryabhatta the Indian mathematician. Very useful information for students. Aryabhatta worked out the value of pi. Aryabhatta describes that the moon and planets shine by light reflected from the sun. Maths is always my favourite subject. Thanks for sharing this useful information.

  31. Yeah as we all know that aryabhatta an indian mathemthecian is worl famous who invented zero, I will say its very informative and wonderful article. Thanx for sharing agood example of a great man.

  32. I have visited India many times and read about India whenever I get a chance. I know about Mahabharat, Ramanuja, Aryabhata and a lot more. I am of the opinion that, none of these persons or reads are getting any importance in India.

  34. Hi,
    I just happen to stumble upon this page..

    Let me first accept that this article deserves its credit. Thanks for all the info. Having said few notings.
    1. “Instead of the prevailing cosmogony where eclipses were believed to be caused by pseudo-planetary nodes Rahu and Ketu,”
    >>> Request you to try and understand what Rahu and Ketu stand for.
    India is not just great for some great people. It is great due to the spiritual content that is more scientific than the modern day science.

    2. Bhat also is a surname from Karnataka.
    >> I would not still try and argue that he might be from Karnataka.
    >> people have the habit of appropriating legacy. That’s fine. we should leave it at that. Most national treasures in whatever form are contested on region/religion/caste etc…

  38. An article about Aryabhata, the mathematician, thanks for your sharing, this is really informative, love to read this awesome post about Aryabhata.

  39. i have doubt mam, iam convinced about the huge contributions of indian astronomical scientists of india.

    But in the internet it is said that they were influenced by babylonian astronomy?…how true is it?
    and what scholars say is that foreigners stole indian knowledge, was transferred to arabs..etc
    what is the truth?
