1. Prthudakasvami
prthudakasvami. Born about 830 in India Died about 890 in India. prthudakasvamiis best known for his work on solving equations.

Extractions: Prthudakasvami is best known for his work on solving equations. The solution of a first-degree indeterminate equation by a method called kuttaka (or "pulveriser") was given by Aryabhata I . This method of finding integer solutions resembles the continued fraction process and can also be seen as a use of the Euclidean algorithm. Brahmagupta seems to have used a method involving continued fractions to find integer solutions of an indeterminate equation of the type ax c by . Prthudakasvami's commentary on Brahmagupta 's work is helpful in showing how "algebra", that is the method of calculating with the unknown, was developing in India. Prthudakasvami discussed the kuttaka method which he renamed as "bijagnita" which means the method of calculating with unknown elements. To see just how this new idea of algebra was developing in India, we look at the notation which was being used by Prthudakasvami in his commentary on Brahmagupta 's Brahma Sputa Siddhanta.

Extractions: VPNEWS PARTING THOUGHTS (II) To continue from where we left off last time, Vigyan Prasar can really make a difference to the overall science popularisation scene in the country! It has all the essential ingredients, in the form of major programmes/efforts, I mentioned last time, to transform itself into a powerhouse of incredible and unimaginable strengths capable of delivering unheard of results! Each one of the VP's major programmes referred to earlier, if handled appropriately, could develop into an independent, self-sustaining entity in its own right, under the overall VP umbrella, with greatly enhanced output. What would that mean in terms of the goals we are seeking to achieve? Vigyan Prasar books would also be distributed worldwide in many countries and also in many other non-Indian languages. Dream-2047 would develop into a very popular science magazine with a large circulation and several other language editions, besides Hindi and English. .

Extractions: VPNEWS ANOTHER VIGYAN PRASAR INITIATIVE TO PROMOTE POPULAR SCIENCE WRITING IN REGIONAL LANGUAGES. 4. Science Quiz Programmes at various levels - local, district, state and national - be initiated in the line of Shri M. V. Kamath's proposal of "Kaun Banega Vigyanpati" to identify brilliant students and award them suitably with scholarships for further studies. Curtains came down on the workshop in the evening of 22 October 2000 with a brief valedictory function where Prof. Hegde, Shri Kamath and Dr. Sehgal placed their erudite comments and observations. Members from the local and national press, officials from MAHE, and overall the writers who assembled at Manipal equivocally praised the pioneering efforts of VP for organizing this workshop and re-affirming its commitment to taking science to the masses. Other subject areas which were covered, though still less prominently, pertained to science and society, announcements of meetings, seminars etc, science popularization, invention/discoveries nuclear science and disasters. About half the coverage (50.8%) was through news and a little over one-quarter (28%) through articles. The remaining items were covered thruogh reports and features.
