Downloads Questions on Sets, Relations and Functions Source : Shutterstock. Sets, Relations and Functions are of utmost importance in the study of mathematics. Most of the students find these topics difficult and hence they tend to avoid studying these in Higher Secondary level. As a result they face a lot of conceptual problems in degree classes. I have
cardinality Infinity Comparision What is infinity? Is it a number or just another mathematical definition to fit our purpose? But then what are numbers? It is pointless asking such questions. The answers are some philosophical thoughts. Then how do we deal with them whenever they arise? Well one question which occured in the
Book Reviews Book Review: The Immortal Life of Henrietta Lacks The art of writing a scientific biography is a very difficult one and has been mastered by very few writers so far. The task becomes all the more difficult if the subject is somewhat controversial and non-conventional. However, all these factors didn’t deter Rbecca Skloot in her fabulous attempt
