Space and time are woven together to form a fourth dimension called ‘space-time’. The ‘curvature’ is a geometric property of space- time. Einstein identified this property while he was working on his General Relativity theory. The curvature of space-time is directly related to the energy and the momentum of any matter or radiation. A standard…

Calculus is a branch of mathematics which studies ‘change’. Accordingly, it deals with limits, derivatives, functions and indefinite series that explain ‘change’. Isaac Newton and Gottfried Wilhelm Leibnitz independently invented calculus. Newton used calculus fundamentally to arrive at the universal law of gravitation, and then to solve the problem of planetary motion, the shape of the surface…
Michael Beran, a scientist at the Georgia State University, trained chimps to use a computer and a joystick. The computer screen showed a numeral followed by a series of dots. The chimps had to match the numeral with the dots. One chimp learned numerals from 1 to 7, while another managed to learn till the numeral…
