"We owe a lot to the Indians, who taught us how to count, without which no worthwhile scientific discovery could have been made."
-- Albert Einstein.
A thread to highlight the achievements of the great Indian civilization.
Ancient India is not typically a civilization that receives a lot of publicity about inventions. However, as with any civilization that last for an extended period of time and flourishes, it has made some notable innovations.

Discovery of Astronomy
August 14, 2009 by jbasdeo, 50 weeks 1 day ago
Comment id: 156
The knowledge of the motion of heavenly bodies was discovered by Aryabhatta (499 AD), Latadeva (505 AD), and Brahmagupta (628 AD), for calculating the timing of eclipses.
In Surya Sidhanta, Latadeva talked about the earth’s axis and called it SUMEGU.
“ That the earth is a sphere and it rotates on its own axis” was known to Varahamihira and other Indian astronomers much before Copernicus published this theory. (Jewish Encyclopedia)

The brick work of Harappa and Mohenjodaro excavations shows that the people of ancient India (2500 BC) possessed knowledge of Geometry.
Aryabhatta formulated the rules for finding the area of a “triangle’, which led to the origin of Trignometry.

In Western Europe the knowledge of Algebra was borrowed, not from Greece but Arabs who acquired this from India.
Algebra is the only Arabic name for Bijaganitha.
“Aryabhatta was one of the first to use Algebra”
(Encyclopedia Britannica).

Invention of Numerals

Numerals are found in the inscriptions of Ashoka the Great in the 3rd Century BC. This knowledge traveled from there to Arab countries and from there to Europe and West. In Arab countries even now numerals are known as HINDSE: 'from India'.
Laplace, the French mathematician and physicist, wrote during Napoleon’s time, “It is India that gave us the ingenious method of expressing all numbers by means of ten symbols. “
-Prof. O.M. Mathew in Bhavan’s Journal.”
