    far from any educational activity, proved to be the most important work publishedin India after SiddhantaShiromani (written in AD 1150) by bhaskara ii.  
    http://www.vigyanprasar.com/dream/august99/AUGUSTArticle2.htm
    
    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:

    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. Currently, the following table of contents is proposed for this volume:

27. Biography Of Sridhara

    http://www.cabrillo.edu/~stappero/Sridhara.htm
    
    Extractions: Biography of Sridhara Sridhara was born around the year 870, although historians are unsure about this date. Estimates indicate that he wrote in about 900 AD, from examining other works of mathematics that he was familiar with and seeing which later mathematicians were familiar with his work. Historians place his birthplace in two very different location; one hypothesis is that he was born in Bengal, India, while other historians would assert that he was born in southern India. Sridhara penned his name to two mathematical treatises, called the Trisatika (sometimes called the Patiganitasara ) and the Patiganita However, three other mathematicians have attributed other works to his name. The works of Bhaskara II (writing around 1150), Makkibhatta, and cite the books the Bijaganita Navasati , and Brhatpati as being written by Sridhara. The Patiganita is written in the form of a poem; it details tables of monetary and metrological units. The algorithms in the novel are designed to carry out basic arithmetic operations such as: squaring, cubing, and square and cube root extraction. Sridhara gives rules to solve problems in a verse format, as was the trend in Indian texts at that time.

    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.

    Extractions: Year 1719 A.D., Place : Delhi, Location : Red Fort - A noisy session about the auspicious time for the emperor Mohammed Shah to embark upon a big expedition. The maulvis and pandits did not have astronomical laboratories to verify the calculations and hence the confusion and debate. The spectator was Maharaj Sawai Jai Singh II. He decided to construct huge stone astronomical observatories to educate people. By 1724 A.D., the first observatory at Delhi was completed. The maharaja himself carried out experiments and observations for nearly seven years at this observatory. The next one was constructed at Jaipur in 1728 A.D. and the others at Ujjain, Varanasi and Mathura. All the yantras were made of red sand stone, marble and iron. Sawai Jai Singh wanted to promote the scientific approach to astonomy and astrology. To acquaint people with the scientific aspect of the Sun, moon, stars and the various astronomical phenomena, he designed the various yantras. Let us learn how to use some of these yantras. You can also make your own DhoopGari (Sundial) and star clock.

34. Applications Of Integration
    For example, bhaskara ii, a well known Indian mathematician of middle ageswrote a math book Lilavati in 1150 AD in the memory of his daughter.

    Extractions: Author Ravinder Kumar This 9-page microworld explores arc length of a curve, area under a curve, and surface area and volume of revolution. For simplicity we explore only those surfaces of revolution that can be obtained by revolving a curve about x-axis. Arc length, area, surface area, and volume can be found by dividing the arc, region, or solid into tiny portions in Riemannian spirit. You will be living in Riemannian spirit as you conduct explorations on the following interactive pages. The theory will be briefly explained on the help pages that can be viewed by pressing the button “math for this page”. Often an example or two may be used to explain the theory. When a page of the microworld contains a button named “instructions”, you can press it to view instructions for using the interactivity of the page in order to make explorations. Seeds for the ideas of integration that lead up to finding area and volume were sown much earlier than the advent of calculus.

    Extractions: The above picture is my favourite proof of Pythagoras' theorem. Filling in the details is left as an exercise to the reader. This proof is sometimes referred to as the Chinese square proof , or just the Chinese proof . It is supposed to have appeared in the Chou pei suan ching (ca. 1100 B.C.E.), according to Ralph H. Abraham [see ``Dead links'' below,] who attributes this information to the book by Frank J. Swetz and T. I. Kao, Was Pythagoras Chinese? . See also Development of Mathematics in Ancient China According to David E. Joyce 's A brief outline of the history of Chinese mathematics , however, the earliest known proof of Pythagoras is given by Zhoubi suanjing (The Arithmetical Classic of the Gnomon and the Circular Paths of Heaven) (c. 100 B.C.E.-c. 100 C.E.) In the The MacTutor History of Mathematics archive there is a section devoted to Chinese mathematics . The overview section at that section also mentions the Zhoubi suanjing is a proof as well.
