Algebra, trigonometry and calculus came from India; Quadratic equations were by Sridharacharya in the 11th century; The largest numbers the Greeks and the Romans used were (10 to the power of 6) whereas Hindus used numbers as big as (10 to the power of 53) with specific names as early as 5000 BC during the Vedic period.

There are several success stories like Rabindranath Tagore (1913 Nobel Prize in Literature), CV Raman (1930 Nobel prize for Raman effect), JC Bose’s discovery of microwaves by 1895 and Prof. Jagdeesh Bose (USA based IEEE has proved what has been a century-old suspicion in the world scientific community that the pioneer of Wireless communication was not Marconi).
The European Food Safety Authority and many others recommend that women should drink about 1.6 litres of fluid and men should drink about 2.0 litres of fluid per day. That's about eight glasses of 200ml each for a woman, and 10 glasses of 200ml each for a man. However, the amount a person needs to drink to avoid getting dehydrated will vary depending on a range of factors, including their size, the temperature and how active they are. So, for example, if you're exercising hard in hot weather you'll need to drink more.
All drinks count, including hot drinks such as tea and coffee, but water, milk and fruit juices are the healthiest. It is best to avoid alcoholic drinks.
Also, try to avoid sugary, soft and fizzy drinks that can be high in added sugars. These can be high in calories and bad for teeth.
