Ya u said it right! we owe a lot to indians that doesnt mean present india it means the indian subcontinent and we all owe it to the indian civilisation and not any religion which includes some parts of iran (land of aryans), pakistan, afganistan, bangladesh, srilanka, and by the way sind river is in pakistan now. but some of your claims are wrong the number system which we follow through out the world r called arabic numericals the arabs discovered decimal point, the word ALGEBRA The name is derived from the treatise written by the Persian mathematician Muhammad ibn M%u016Bs%u0101 al-Khw%u0101rizm%u012B titled (in Arabic %u0643%u062A%u0627%u0628 %u0627%u0644%u062C%u0628%u0631 %u0648%u0627%u0644%u0645%u0642%u0627%u0628%u0644%u0629 )Al-Kitab al-Jabr wa-l-Muqabala (meaning "The Compendious Book on Calculation by Completion and Balancing"), which provided symbolic operations for the systematic solution of linear and quadratic equations.the arabs were the first to measure the distance between the earth and the moom in 800AD they were the first draw maps of land and sea for navigation. ALL of todays organic chemistry fundamentals are based on Arab research many terms like ALCOHOL, ETHERS, ESTERS,etc are arabic words and we cannot neglect the contribution of the europeans who shaped our mordern science and technology like television, computers,etc, chinese were the first to make a mechanical clock , egypitian invented the wheel and made pyramds 3000 years ago all these civilisation contributed in building up of the knowledge we have now SO mature up a bit see around u dont listen to crap, put ur time in doing some thing good for your country so that our great nation goes back to its glory days. and one last thing HINDU is not a religion it is a geographical term given to the people living between himalays and sindhu river in that way people living in the subcontinent irrespectie of their religion are hindu. the brilliant people in india call themselves hindu because they dont know the name of their religion isn't that genius
