Nature of physical laws Summary Exercises Humans have consistently been interested about their general surroundings. The night sky with its brilliant heavenly items has captivated people since days of yore. The normal reiterations of the day and night, the yearly pattern of seasons, the shrouds, the tides, the volcanoes, the rainbow have consistent ly been a wellspring of miracle. The world has an amazing assortment of materials and a confusing decent variety of life and conduct. The inquisitive and innovative human psyche has reacted to the marvel and wonder of nature in various manners. One sort of reaction from the most punctual occasions has been to watch the hysical condition cautiously, search for any important examples and relations in regular wonders, and manufacture and utilize new instruments to cooperate with nature. This human undertaking drove, in course of time, to present day science and innovation. The word Science begins from the Latin action word Scientia meaning ‘to know’. The Sanskrit word Vijnan and the Arabic word Ilm c onvey comparable importance, specifically ‘knowledge’. Science, from an expansive perspective, is as old as human species. The early civilisations of Egypt, India, China, Greece, Mesopotamia and numerous others gained essential commitments to its ground. From the sixteenth century onwards, incredible steps were made n science in Europe. By the center of the twentieth century, science had become a genuinely worldwide endeavor, with numerous societies and nations adding to its fast development. What is Science and what is the supposed Scientific Method ? Science is an efficient endeavor to comprehend regular marvels in however much detail and profundity as could be expected, and utilize the information so picked up to anticipate, change and control wonders. Science is investigating, testing and anticipating from what we see around us. The interest to find out about the world, disentangling the privileged insights of nature is the initial move towards the disclosure of science. The logical technique includes a few interconnected advances : Systematic perceptions, controlled tests, subjective and
