Hi   Dear Mr   Please do not vandalize like you did to Fourier inversion formula Math is a wonderful subject even if you dont appreciate it Mathematicians do something useful for the world and what they do lasts for centuries They also enjoy what they do If by get a life you mean go to parties get drunk and crash your car into another car and die then its obvious to anyone with a modicum of intelligence that mathematics is far superior  Also you have no right to criticize people who do math unless you yourself can understand what they do The mathematics you have criticized is deep and interesting and you shouldnt insult it unless you understand it I hate the mentality that if you dont understand something you need to criticize it It tells more about you than it does about the people who do math  Good luck
