The immense potential of science and technology has set human kind rethinking about its use.We humans have so far developed a lot when it comes to the criteria of science and technology.Some theories and laws have more than just one use.This has sent the scientists to the base of those laws and have made them rethink about their use and what else they can be used for.This has led to the invention of various advanced machines like laser engraver, laser machine,etc
