I love this culture. When I started researching ancient civ all those years ago, I merely thought about Egypt and the pyramids. I've since learned how naive I was about the "oldest" cultures on this planet. And they weren't as backwards and uneducated as one might think, either.

Here's a bit of history from just one culture:

India

* India invented the Number System. Zero was invented by Aryabhatta. The place value system, the decimal system was developed in India in 100 BC.

* Aryabhatta was the first to explain spherical shape, size ,diameter, rotation and correct speed of Earth in 499 AD.

* The World's first university was established in Takshila in 700 BC. Students from all over the World studied more than 60 subjects.

* The University of Nalanda built in the 4th century was one of the greatest achievements of ancient India in the field of education.

* Sanskrit is considered the mother of all higher languages. Sanskrit is the most precise, and therefore suitable language for computer software - a report in Forbes magazine, July 1987.

* Ayurveda is the earliest school of medicine known to humans. Charaka, the father of medicine consolidated Ayurveda 2500 years ago.

* Today Ayurveda is fast regaining its rightful place in civilization.

* Christopher Columbus was attracted India's wealth and was looking for route to India when he discovered the American continent by mistake.

* The art of Navigation was born in the river Sindh 6000 years ago. The word ‘Navigation’ is derived from the Sanskrit word NAVGATIH. The word navy is also derived from Sanskrit 'Nou'.

* In Siddhanta Siromani (Bhuvanakosam 6) Bhaskaracharya II described about gravity of earth about 400 years before Sir Isaac Newton. He also had some clear notions on differential calculus, and the Theory of Continued Fraction.

* Theory of Continued Fraction was discovered by Bhaskaracharya II.

* Indians discovered Arithmetic and Geometric progression. Arithmetic progression is explained in Yajurveda.

* Govindaswamin discovered Newton Gauss Interpolation formula about 1800 years before Newton.

* Vateswaracharya discovered Newton Gauss Backward Interpolation formula about 1000 years before Newton.

* Parameswaracharya discovered Lhuiler’s formula about 400 years before Lhuiler.

* Nilakanta discovered Newton’s Infinite Geometric Progression convergent series.

* Positive and Negative numbers and their calculations were explained first by Brahmagupta in his book Brahmasputa Siddhanta.

* Aryabhatta also propounded the Heliocentric theory of gravitation, thus predating Copernicus by almost one thousand years.

* Madhavacharya discovered Taylor series of Sine and Cosine function about 250 years before Taylor.

* Madhavacharya discovered Newton Power series.

* Madhavacharya discovered Gregory Leibnitz series for the Inverse Tangent about 280 years before Gregory.

* Madhavacharya discovered Leibnitz power series for pi about 300 years before Leibnitz.

* Bhaskaracharya calculated the time taken by the earth to orbit the sun hundreds of years before the astronomer Smart. Time taken by earth to orbit the sun: (5th century) 365.258756484 days

* Infinity was well known for ancient Indians. Bhaskaracharya II in Beejaganitha(stanza-20) has given clear explanation with examples for infinity
