Sus estudios concernieron sobre astronomía, aritmética, álgebra y trigonometría del plano. Dió fórmulas correctas para calcular las áreas de un triángulo y un círculo. También trató sobre ecuaciones cuadráticas, sumas de serie y una tabla de senos. Dió una aproximación exacta para Pi (equivalente a 3,1416) y fue uno de los primeros en tratar el álgebra en forma profunda. Aryabhata también escribió en el Siddhanta, sobre astronomía y expuso que la rotación clara de los cielos era debida a la rotación de la tierra. Indicó también el radio de las órbitas planetarias en términos del radio de la órbita de la tierra alrededor del sol. Asegura también que la luna y otros planteas brillan por la luz del sol reflejada e increíblemente indica que la órbita de los planetas son elipses. Indica la longitud del año como 365 días, 6 horas, 12 minutos y 30 segundos.

    Extractions: Aryabhata was the first to expound that the Earth is round and days and nights are caused because the Earth rotates around its axis. He also rightly explained about the occurrence of the eclipses. According to the Hindu Mythology, solar and lunar eclipses occur because "Rahu" gobbled up the moon and the sun. But he said the eclipses transpired due to the shadows cast by the Earth and the Moon. His contributions in Mathematics are spectacular and very valuable. He gave the value of (PI) 3.1416, claiming, for the first time that it was just an analogue. It’s believed that he also formulated tables in maths, which later came to be called as the "Tables of Sine". His method to find solution for quadratic equations of the sort: ax(sq.) – by(sq.) = c is also recognised world-wide. He devised a method to write the cumbersome numbers in a poetic form. But this summary is rather complex to grasp. Basically, Aryabhatiya dealt with aspects of mathematics, astronomical calculations, geometry, square root, cube root, progression and celestial sphere, all written in Sanskrit in the form of verses.

    http://www.wiskundeweb.nl/Wiskundegeschiedenis/Wiskundigen/Aryabhata.html
    
    Extractions: Aryabhata is bekend door zijn boek Aryabhatiya dat hij in Kusumapura heeft geschreven in de tijd dat Pataliputra de hoofdstad van het Gupta-Rijk in India was en derhalve een plaats waar de wetenschapsbeoefening in hoog aanzien stond. Kusumapura werd in die tijd (net als Ujjain) een belangrijk centrum van wiskundige activiteit die zich via Pataliputra over de hele Indische en later ook de Arabische beschaving verspreidde. Aryabhata was 23 jaar toen hij de Aryabhatiya in 499 afmaakte. Het gaat daarbij om een boekje over astronomie dat in 118 verzen (sutra's) een samenvatting geeft van kennis van de Hindoes op het gebied van sterrenkunde en wiskunde. In de 33 wiskundige verzen werden 66 stellingen gegeven zonder een spoor van een bewijs. Verder kwamen er verzen in voor over tijdrekening en modellen van het planetenstelsel. Het zijn allemaal typisch voorbeelden van de zaken die in de voorgaande eeuwen voor de op religie gestoelde machthebbers en wetenschapsbeoefenaren interessant waren. Aryabhata was hoofd van het onderzoekscentrum voor wiskunde en astronomie in Kusumapura. Daar ontstond een school van volgelingen die zijn gedachtengoed verder uitwerkten en nog jarenlang de agenda voor wiskundig en sterrenkundig onderzoek in India bepaalden.

    Extractions: ACI Math Department Home Page Aryabhata (475 A.D. -550 A.D.) is the first well known Indian mathematician. Born in Kerala, he completed his studies at the university of Nalanda. We know the year of Aryabhata's birth since he tells us that he was twenty-three years of age when he wrote Aryabhatiya which he finished in 499. there have been numerous other places proposed by historians as his birthplace. Some conjecture that he was born in south India, perhaps Kerala, Tamil Nadu or Andhra Pradesh, while others conjecture that he was born in the north-east of India, perhaps in Bengal. However, giving Asmaka as Aryabhata's birthplace rests on a comment made by Nilakantha Somayaji in the late 15th century. It is now thought by most historians that Nilakantha confused Aryabhata with Bhaskara I who was a later commentator on the Aryabhatiya. We should note that Kusumapura became one of the two major mathematical centers of India, the other being Ujjain. Pataliputra, being the capital of the Gupta empire at the time of Aryabhata, was the center of a communications network which allowed learning from other parts of the world to reach it easily, and also allowed the mathematical and astronomical advances made by Aryabhata and his school to reach across India and also eventually into the Islamic world.

    Extractions: by Manikant Shah In his article on Planetary constants K D Abhyankar tries to show that certain concepts used by Aryabhata in his treatises on Astronomy and Mathematics were probably influenced by the Babylonian planetary data. In his foreword to the 'Aryabhatiya of Aryabhata' edited by KV Sharma in 1976, B P Pal (the then president of the Indian National Science Academy) wrote that due to his contributions to the fields of Astronomy and Mathematics Aryabhata has rightly been regarded as the founder of scientific astronomy in India. In his introductory remarks in the essay 'Aryabhata- the father of epicyclical astronomy' ( History of Science in India vol.2), PC Sengupta states that 'from his own statement made in the Kala Kriya section of his Aryabhatiyam , we know that Aryabhata was born in the year 476 of the Christian Era, that he wrote this famous book (Aryabhatiya) at the age of 23 and that his native place was most probably Kusumapura, Patliputra or the modern city of Patna.' So great was his status in this respect, that whoever differed from Aryabhata was a subject of ridicule. Sengupta further writes that the Indian epicyclic astronomy was constructed by Aryabhata , from whom alone all the later Indian astronomers drew their inspiration. It is clear that Aryabhata had a wide reputation in India, but Abhyankar shows that the concepts of

    Extractions: EIW ... States Saturday, October 17, 1998 PRESS TRUST OF INDIA MUMBAI, Oct 16: Two western researchers have hailed the fifth century Indian astronomer Aryabhata as a genius in his own right and paid tributes to his mathematical acumen. James Jacobs Quirinus, an independent researcher in Athens, Greece and a Swedish scholar Bo Klintberg at the London School of Economics and Political Science, have communicated through the internet with the Thane-based Institute of Oriental Study regarding their studies on Aryabhata. Quirinus, who has created his own Aryabhata web page, has noted that the ancient astronomer born at Kusumapura (now Patna) in Bihar was born in 476 AD and came out with his magnum opus Aryabhatiya in verse form around 499 summarizing his concept of astronomy, spherical trignometry, arithmetic, algebra and plane trignometry. ``However some of his formulas are correct, while others are not,'' Quirinus has noted. Aryabhata is the first known astronomer to have initiated a continuous counting of solar days, designating each day with a number, theGreek researcher said adding ``his astronomic ratio, which is to the best of my knowledge the earliest recorded one, is so incredibly accurate that it surprises me that this fact has gone unnoticed to this date.''

It coveres astronomy, spherical trigonometry, arithmetic, algebra and plane trigonometry. Aryabhata gives formulas for the areas of a triangle and a circle which are correct, but the formulas for the volumes of a sphere and a pyramid are wrong. Aryabhatiya also contains continued fractions, quadratic equations, sums of power series and a table of sines. Aryabhata gave an accurate approximation for (equivalent to 3.1416) and was one of the first known to use algebra. He also introduced the versine ( versin = 1 - cos) into trigonometry. Aryabhata also wrote the astronomy text Siddhanta which taught that the apparent rotation of the heavens was due to the axial rotation of the Earth. The work is written in 121 stanzas. It gives a quite remarkable view of the nature of the solar system. Aryabhata gives the radius of the planetary orbits in terms of the radius of the Earth/Sun orbit as essentially their periods of rotation around the Sun. He believes that the Moon and planets shine by reflected sunlight, incredibly he believes that the orbits of the planets are ellipses. He correctly explains the causes of eclipses of the Sun and the Moon.
