INDIAN MATHEMATICS & MATHEMATICIANS The evolution of Hindu-Arabic numerals Despite developing quite independently of Chinese (and probably also of Babylonian mathematics), some very advanced mathematical discoveries were made at a very early time in India. Mantras from the early Vedic period (before 1000 BCE) invoke powers of ten from a hundred all the way up […]

2012/10/1· Even if every atom in the whole earth were carbon-14, they would decay so quickly that no carbon-14 would be left on earth after only 1 million years. Contrary to expectations, between 1984 and 1998 alone, the scientific literature reported carbon-14 in 70 samples

What is the atom structure, though? The concept that atoms existed was first written about in ancient India in the 6th century B.C. The theory stayed just that, a theory, until the late 19th century.
Problem 1. The distance between the carbon atom and the oxygen atom in a carbon monoxide molecule is 1.1 Å. Given, mass of carbon atom is 12 a.m.u. and mass of oxygen atom is 16 a.m.u., calculate the position of the center of mass of the carbon (a) 6
