Science by Indians

GO TOTAMIL VERSION

Follow the below statement:

Katyayana says that the rope stretched along the length of the diagonal of a rectangle makes an area which the vertical and horizontal sides makes together.

It was only actaully re-defined by Pythagorus. (What an injustice to Indian Science!)

In the field of Trignometry, Aryabhata contributed much before Europeans.

Indians used 'jya' and 'kotijya' which later one became to be known as cosine in European languages.
Aryabhata first composed 'Jya kostaka'.

Jya      - Sine
Kojya  - Cosine
Utkramajya - (1 -Cos x)

With this trignometery Indian mathematicians developed astonomy and geometry.

Jya is Chord of circle
chappa - arc of a circle
vyasrdha - radius of a circle

Brahmagupta, Bhaskara, famous Jain Mahavira, Paramaswara, Sridhara are famous vedic mathematicians.
Aryabhatta in 499 AD worked the value of Pi to the fourth decimal place as 3.1416. Centuries later, in 825 AD, Arab mathematician Mohammed Ibna Musa says that "This value has been given by the Hindus (Indians)".

Europeans again got the credit.

In the field of Physics

The earliest recorded use of copperware in India has been around 3000 B.C.

"The Hindus excel in the manufacture of iron. They have also workshops wherein are forged the most famous sabres in the world. It is impossible to find anything to surpass the edge that you get from Indian Steel"

Shankaramishra had propounded fundamental principles of Magnetism.He tells about how and why a metal pin is attracted towards a magnet.

Bhoja(1050AD) had ordered that ships should not have metals at the bottom which he thought that the magnetic part that exists in the rocks of the sea may draw ships towards them and cause ship wreck.
Compass which were used by sea voyager Hindus were called Matsyayantra.

Ancient Indian Epics Mahabharata and Ramayana have references of Atomic and Nuclear weapons.

Not only above but also Indian scientists have contributed many concepts much before Europeans, Americans, Greek, Egyptians but the Mughals, British invasaion had destroyed our trade mark in the world.

Next time if any foreigner or an India espcially an NRI asks you what is in India except beggars and garbage
qoute all the points and make them realise India is only the root of many present science.
