INTRODUCTION

The word ‘Science ‘is derived from the Latin (Roman) word ‘Scientist’ which means knowledge. Science deals with the understanding of natural phenomena and the relations between them and its and is the rational interpretation of facts of existence as disclosed to us by our faculties and senses. The hypotheses of Science. According to a great thinker, Karl Pearson are formed on the basis of the observed facts, which, when confirmed by criticism and experiments are turned into the “Law of Nature”. In the words of J. Arthur Thomson.” Science is the well-criticized body of empirical knowledge declaring in the simplest and Tenant terms available at the time what can be observed and experimented with, and summing up uniformity of change in formula which are called laws verifiable by all who can use methods.‘ Hypothesis, theory and law seems to be the vertices of the triangle of science based on experiments and observation.

Science, as indicated by one word reference, is “the orderly investigation of the nature and conduct of the material and physical universe, in light of perception, examination, and estimation.” To do the greater part of that is hard, regularly baffling, work. Researchers battle with examinations and perceptions for quite a long time, months, or even years. Here and there their works prompt deadlocks, yet much of the time they convey advantages to humankind. Think about a couple of illustrations.

A European organization has consolidated solid plastic and propelled channels to deliver a gadget that has made it feasible for a man to keep away from disease from drinking polluted water. Gadgets like that one have been put to use amid catastrophic events, for example, the 2010 quake in Haiti.

High over the earth, systems of satellites make up what is known as the Worldwide Situating Framework (GPS). Initially intended for military applications, the GPS helps drivers, plane pilots, dispatch guides, and even seekers and climbers to discover their direction. On account of the researchers who created it, the GPS makes it less demanding to get to where you need to go.

Do you utilize a wireless, a PC, or the Web? Have you seen that your wellbeing has enhanced or has been reestablished due to cutting edge drug? Do you go via plane? Assuming this is the case, you are profiting from a portion of the manners by which science has been a shelter to mankind. Science has influenced your life in numerous positive ways.

With an end goal to extend their frame of reference, present day researchers are looking profound into the regular world. Atomic physicists look into the inward workings of the iota, while astrophysicists follow back billions of years, trying to comprehend the beginning of the universe. As they test profound and far, even into domains that are

Imperceptible and untouchable, a few researchers feel that if the Lord of the Book of scriptures exists, they ought to have the capacity to discover him.

Some unmistakable researchers and savants go further. They bear on what science creator Amir D. Aczel called “a logical contention against the presence of God.” For instance, a world-well known physicist guaranteed that “the nonappearance of confirmation for any God who assumes a critical part in the universe demonstrates past a sensible uncertainty that such a divine being does not exist.” Others insinuate the movement of the Lord of the Book of scriptures as “enchantment” and “heavenly shenanigans.”

In any case, the inquiry must be asked: Has science sufficiently adapted about the regular world to have the capacity to make complete determinations? The basic answer is no. Science has gained huge ground, however numerous researchers perceive that there are as yet numerous questions and maybe unknowable. “We will never get to the base of things,” said physicist and Nobel laureate Steven Weinberg on understanding nature. Teacher Martin Rees, Stargazer Regal of Extraordinary England, stated: “There might be things that people will never get it.” in all actuality quite a bit of nature, from the modest cell to the tremendous universe, still stays outside the ability to understand of present day science.
