Science is now understood as the field of discovery of the laws of Nature. In common practice, Science is mistaken for technology. Science came into its own when it challenged the ruling thought of superstition in almost all walks of life. Over the centuries, science has lived up to its original claim and now, all over the world, in every field conceivable, science is the ruling philosophy, the inspiring vision and a mental incentive for the multitude. It is said that the conqueror is often conquered.
