An Interesting Conversation -- Must Read An atheist professor of philosophy speaks to his class on the problem science has with God, The Almighty. He asks one of his new students to stand and..... Prof: So you believe in God? Student: Absolutely, sir. Prof: Is God good? Student: Sure. Prof: Is God all-powerful? Student: Yes.

Loss or misuse of constants of integration. The indefinite integral of a function involves an "arbitrary constant", and this causes confusion for many students, because the notation doesn't convey the concept very well. An expression such as "3x2+5x+C" really is supposed to represent an infinite collection of functions -- it represents all of the functions 3x2+5x+7, 3x2+5x+19, 3x2+5x?3.19, etc. plus more functions of the same sort. One of the difficulties, also, is that the same letter "C" is customarily used for all such arbitrary constants; but one computation may involve several different arbitrary constants. It would be more accurate to put s

In 1883, a creative engineer named John Roebling was inspired by an idea to build a spectacular bridge connecting New York with the Long Island. However bridge building experts throughout the world thought that this was an impossible feat and told Roebling to forget the idea. It just could not be done. It was not practical. It had never been done before. Roebling could not ignore the vision he had in his mind of this bridge. He thought about it all the time and he knew deep in his heart that it could be done. He just had to share the dream with someone else. After much discussion and persuasion he managed to convince his son Washington, an up and com

Revising the JEE topics This one poses the maximum challenge to students. With the board exams almost over, how should you go about revising the topics for JEE? We say jot it down. Pick a subject -- say physics -- and go through the detailed syllabus. Go through the components from the beginning. And as you do so, in your mind, go through all the concepts and principles associated with each component in full. Open a note book for this purpose. Whene
