Extractions: Bhaskara is also known as Bhaskara II or as Bhaskaracharya, this latter name meaning "Bhaskara the Teacher". Since he is known in India as Bhaskaracharya we will refer to him throughout this article by that name. Bhaskaracharya's father was a Brahman named Mahesvara. Mahesvara himself was famed as an astrologer. This happened frequently in Indian society with generations of a family being excellent mathematicians and often acting as teachers to other family members. Bhaskaracharya became head of the astronomical observatory at Ujjain, the leading mathematical centre in India at that time. Outstanding mathematicians such as Varahamihira and Brahmagupta had worked there and built up a strong school of mathematical astronomy. In many ways Bhaskaracharya represents the peak of mathematical knowledge in the 12th century. He reached an understanding of the number systems and solving equations which was not to be achieved in Europe for several centuries. Six works by Bhaskaracharya are known but a seventh work, which is claimed to be by him, is thought by many historians to be a late forgery. The six works are:

Extractions: (8 VI. Pell's equation) Bhaskaracharya , or Bhaskara II, is regarded almost without question as the greatest Hindu mathematician of all time and his contribution to not just Indian, but world mathematics is undeniable. As L Gurjar states: ...Because of his work India gave a definite 'quota' to the forward world march of the science. [LG, P 104] Born in 1114 AD (in Vijayapura, he belonged to Bijjada Bida) he became head of the Ujjain school of mathematical astronomy ( Varahamihira and Brahmagupta had helped to found this school or at least 'build it up'). There is some confusion amongst the texts I have referred to as to the works that he wrote. C Srinivasiengar claims he wrote Siddhanta Siromani in 1150 AD, which contained four sections: Lilavati (arithmetic) Grahaganita (mathematics of the planets) E Robertson and J O'Connor claim that he wrote 6 works, 1), 2) and SS (which contained two sections) and three further astronomical works, including two commentaries on the SS. G Joseph claims his mathematically significant works were 1), 2), and SS (which indeed he wrote in 1150 and is a highly influential astronomical work). S Sinha however agrees with C Srinivasiengar that

Extractions: Bhaskara II perfects Bramagupta's method for solving the varga prakriti by providing a method for solving the equation Nx^2 + k = y^2, when k = -4, -2, -1, +1, +2, +4. Bhaskara calls this method the Chakravala or the cyclic process. I will explain the cyclic method by means of an example taken from Siddhanta Siroman of Bhaskara. Bhaskara demonstrates how to find the solution of the equation y^2 = 67x^2 + 1. He starts with the pairs (1,8) and (1,s). (1,8) satisfies y^2 = 67x^2 -3, with "additive" -3, while (1,s) satisfies the equation y^2 = 67x^2 + (s^2 - 67) with "additive" (s^2 - 67). Bhaskara then applies the principle of composition or Samasa process of Bramagupta modification to Kuttaka ) to Aryabhata 's solution of this equation ( Kuttaka

Extractions: Leading astronomers of this period were Aryabhata I (born A.D. 476), Varahamihira (6th century A.D.), Bhaskara I (born c. A.D. 600), Brahmagupta (born c. A.D. 598), and Bhaskara II (born A.D. 1114). Besides the compilation work of Varahamihira, the immortal works of this period were Aryabhatia (by Aryabhata I), Brahmasphuta-siddhanta (by Brahmagupta) and Siddhanta-Shiromani (by Bhaskara II). with the help of commentaries. By the age of 15 he mastered the rules for calculating the ephemerides (tables showing the positions of heavenly bodies at regular intervals in time) of the planets. While calculating the positions of the planets he found that neither the stars appeared on the horizon at the right moment nor could the planets be seen in the right places. He began to observe and calculate the movement of heavenly bodies night after night. At the age of 23 he began to note down systematically the results of his observations. The journal Knowledge which reviewed the book in 1899 wrote: Pathani Samanta made contributions to the following four important aspects of astronomy:

It contains the first English translation (and the first translation into any western language) of any mathematical work of Brahmagupta, the greatest Indian mathematician of his period, as well as translations of the works on arithmetic and algebra by his successor Bhaskara II. Brahmagupta was born in 598 A.D. in northwestern India. His major work, the Brahmasphutasiddhanta (Correct Astronomical System of Brahma) was written when he was 30; the mathematical work translated here constitutes its 12th chapter. It treats the solution of linear and quadratic equations, and linear congruences, leading to the solution of the so-called Pell's equation ax2 + b = y2 (a and b being given integers and x and y integers to be found). This equation occurs for the first time in Brahmagupta's work, although it was misnamed by Euler after the 17th century English mathematician John Pell. Brahmagupta's work on Pell's equation was not really superseded until Fermat studied it a millennium later.

http://www.infinityfoundation.com/mandala/t_dy/t_dy_Q13.htm

Extractions: By D.P. Agrawal Bhaskaracarya was a mathematician-astronomer of exceptional abilities. He was born in 1114 AD. Mathematics became the hand-maiden of astronomy and, from the time of Aryabhata I, it began to be incorporated in astronomical treatises. Thus all components of mathematics came to be developed: geometry, trigonometry, arithmetic and algebra. The great astronomers had to be great mathematicians too. The great astronomer-mathematicians of the Siddhanta period, in a chronological order were: Aryabhata I, Varahamihira, Brahmagupta, Aryabhata II, Sripati, Bhaskara II (known popularly as Bhaskaracarya), Madhava, Paramesvara and Nilakantha. These great scientists, except the last three, grew in different parts of this vast sub-continent. Perhaps such isolated growth may explain the apparent abruptness in astronomical and mathematical development in India. Even before Bhaskara made his mark on Indian Jyotisa, there were three distinct schools, the Saura, the Arya and Brahma. Bhaskara was respected and studied even in distant corners of India. Bhaskara was perhaps the last and the greatest astronomer that India ever produced. Brahmagupta was Bhaskara's role model and inspirer. To Brahmagupta he pays homage at the beginning of his

Extractions: Subhash Kak, Editor This sourcebook will consist primarily of reprinted articles on Indic contributions in math and science, as well as several new essays to contextualize these works. It will bring together the works of top scholars which are currently scattered thoughout disparate journals, and will thus make them far more accessible to the average reader. There are two main reasons why this sourcebook is being assembled. First, it is our hope that by highlighting the work of ancient and medieval Indian scientists we might challenge the stereotype that Indian thought is "mystical" and "irrational". Secondly, by pointing out the numerous achievements of Indian scientists, we hope to show that India had a scientific "renaissance" that was at least as important as the European renaissance which followed it, and which, indeed, is deeply indebted to it.

Smith, "was to Christian Europe what the 9th Century was to the eastern Mohammedan world, a period of translations . In the case of Baghdad, these translations were from the Greek into Arabic; in the case of Christian Europe, from the Arabic into Latin. The reasons for this desire to know the science of the East are not difficult to find.... the advancement of Moorish Spain in the arts and sciences was already causing intellectual unrest in the higher classes of Church schools in France, Italy, and England. The result of this unrest was an influx of students into Spain, an acquiring of some knowledge of Arabic on the part of various scholars, and a strong desire to know and make known the science of the East. Just as Baghdad never translated the Greek literature, but sought to known Greek science, so Europe gave little attention to Arab letters, but devoted great care to those works on

Extractions: Sobre Lilavati, conta Malba Tahan, em seu livro O Homem que Calculava "Baskara tinha uma filha chamada Lilavati . Quando essa menina nasceu, consultou ele as estrelas e verificou, pela disposição dos astros, que sua filha, condenada a permanecer solteira toda a vida, ficaria esquecida pelo amor dos jovens patrícios. Não se conformou Baskara com essa determinação do Destino e recorreu aos ensinamentos dos astrólogos mais famosos do tempo. Como fazer para que a graciosa Lilavati pudesse obter marido, sendo feliz no casamento? Um astrólogo, consultado por Baskara, aconselhou-a a casar Lilavati com o primeiro pretendente que aparecesse, mas demonstrou que a única hora propícia para a cerimónia do enlace seria marcada, em certo dia, pelo cilindro do Tempo. Os hindus mediam, calculavam e determinavam as horas do dia com o auxílio de um cilindro colocado num vaso cheio d'água. Esse cilindro, aberto apenas em cima, apresentava um pequeno orifício no centro da superfície da base. À proporção que a água, entrando pelo orifício da base, invadia lentamente o cilindro, este afundava no vaso e de tal modo que chegava a desaparecer por completo em hora previamente determinada.
