Assam is endowed with petroleum, natural gas, coal, limestone and many other minor minerals such as magnetic quartzite, kaolin, sillimanites, clay and feldspar.A small quantity of iron ore is also available in western parts of Assam.
A Course of Pure Mathematics is a classic textbook in introductory mathematical analysis, written by G. H. Hardy. It is recommended for people studying calculus. First published in 1908, it went through ten editions (up to 1952) and several reprints. It is now out of copyright in UK and is downloadable from various internet web sites.
In the above figure, P 1 has a winning strategy as follows: N 1 points only to nodes N 2 and N 3. Thus P 1 's first move must be one of these two choices. P 1 chooses N 2 (if P 1 chooses N 3, then P 2 will choose N 9 as that is the only option and P 1 will lose). Next P 2 chooses N 4 because it is the only remaining choice. P 1 now chooses N 5 ...
However, if only the Earth's land area of 150,000,000 km 2 (58,000,000 sq mi) is taken into account, then human population density is 53/km 2 (140/sq mi). This includes all continental and island land area, including Antarctica. However, if Antarctica is excluded, then population density rises to over 58 per square kilometre (150/sq mi). [1]
The oceans cover an area of 361.8 million km 2 (139.7 million sq mi) with a mean depth of 3,682 m (12,080 ft), resulting in an estimated volume of 1.332 billion km 3 (320 million cu mi). [ 195 ] If all of Earth's crustal surface were at the same elevation as a smooth sphere, the depth of the resulting world ocean would be 2.7 to 2.8 km (1.68 to ...
It is spread over an area of 83,743 km 2 (32,333 sq mi). [ 3 ] 98% of the geographical area is land out of which 80% is forest cover; [ 1 ] 2% is water. [ 4 ] River systems in the region, including those from the higher Himalayas and Patkoi and Arakan Ranges , eventually drain into the Brahmaputra River .
1 Relative to the African plate The Indian plate (or India plate ) is a minor tectonic plate straddling the equator in the Eastern Hemisphere . Originally a part of the ancient continent of Gondwana , the Indian plate broke away from the other fragments of Gondwana 100 million years ago and began moving north, carrying Insular India with it.

Smale's problems is a list of eighteen unsolved problems in mathematics proposed by Steve Smale in 1998 [1] and republished in 1999. [2] Smale composed this list in reply to a request from Vladimir Arnold, then vice-president of the International Mathematical Union, who asked several mathematicians to propose a list of problems for the 21st century.
