For those who are unaware‚ at least 1 and 2 are thanks to Georg Cantor and his invention of set theory. He had to endure a lot of resistance from the mathematical luminaries of his day - Kronecker and apparently‚ even Poincaré! Like Nietzsche‚ he died in a mental institution‚ the vicious attacks on his ideas (mostly by Kronecker) having supposedly played a part in Cantor’s breakdown. His mathematical ideas also ran afoul of some religious "philosophers" who‚ as is usually the case‚ are never ever

Economic Reforms in India since 1991 India was a latecomer to economic reforms‚ embarking on the process in earnest only in 1991‚ in the wake of an exceptionally severe balance of payments crisis. The need for a policy shift had become evident much earlier‚ as many countries in East Asia achieved high growth and poverty reduction through policies which emphasized greater export orientation and encouragement of the private sector. India took some steps in this direction in the 1980s‚ but it was

space‚ and change‚ exists throughout the entire universe. It attempts to provide some solid explanation for the seemingly random chaos in the world. Mathematicians search for patterns that are present in life and that apply to the numerous laws of math. There are several fields of mathematics‚ some of the simpler ones being algebra‚ geometry‚ trigonometry‚ and calculus. One subject in particular that illustrates mathematical concepts is the game of football‚ or commonly known as soccer. I have

Math Phobia Math phobia‚ which is exhibited by many students‚ is the persistent‚ illogical‚ intense fear of not succeeding in math. It is the belief that one is unable to handle the difficulty associated with learning math. Many people incorrectly assume that math phobia and an inability to be successful in mathematics are inherited from one’s parents. Several legitimate factors contribute to‚ and increase the severity of‚ this perception. For instance‚ gender and ethnic backgrounds are not
