 Particle accelerators are devices through which we accelerate charge particles and we collide them to analyze the debris. It has produced wonderful results giving rise to a number of particles that could challenge the naming convention of life sciences. The ground braking discoveries of twentieth century the quantum mechanics and relativity have truly showed what a magical universe we are part of . Roughly speaking quantum mechanics the laws which completely defies the classical ideas of F=ma and the probabilistic world of small not the Newtonian deterministic world .On the other hand the General theory of relativity which again implies things beyond human imagination and senses more...
