Jump to navigation. Benjamin Franklin was many things in his lifetime: a printer, a postmaster, an ambassador, an author, a scientist, a Founding Father. Above all, he was an inventor, creating solutions to common problems, innovating new technology, and even making life a little more musical. Despite creating some of the most successful and popular inventions of the modern world, Franklin never patented a single one, believing that they should be shared freely: "That as we enjoy great Advantages from the Inventions of others, we should be glad of an Opportunity to serve others by any Invention of ours; and this we should do freely and generously. By , he had turned his attention to the possibility of protecting buildings—and the people inside—from lightning strikes. Having noticed that a sharp iron needle conducted electricity away from a charged metal sphere, he theorized that such a design could be useful:. Would not these pointed rods probably draw the electrical fire silently out of a cloud before it came nigh enough to strike, and thereby secure us from that most sudden and terrible mischief!

This list of Indian inventions and discoveries details the inventions, scientific discoveries and contributions of India, including the ancient, classical and post-classical nations in the subcontinent historically referred to as India and the modern Indian state. It draws from the whole cultural and technological history of India, during which architecture , astronomy , cartography , metallurgy , logic , mathematics , metrology and mineralogy were among the branches of study pursued by its scholars. For the purposes of this list, inventions are regarded as technological firsts developed in India, and as such does not include foreign technologies which India acquired through contact. It also does not include technologies or discoveries developed elsewhere and later invented separately in India, nor inventions by Indian emigres in other places.

Polymers abound in nature. Cellulose, the material that makes up the cell walls of plants, is a very common natural polymer. Over the last century and a half humans have learned how to make synthetic polymers, sometimes using natural substances like cellulose, but more often using the plentiful carbon atoms provided by petroleum and other fossil fuels. Synthetic polymers are made up of long chains of atoms, arranged in repeating units, often much longer than those found in nature. It is the length of these chains, and the patterns in which they are arrayed, that make polymers strong, lightweight, and flexible. These properties make synthetic polymers exceptionally useful, and since we learned how to create and manipulate them, polymers have become an essential part of our lives.

Galileo , in full Galileo Galilei , born February 15, , Pisa [Italy]—died January 8, , Arcetri, near Florence , Italian natural philosopher, astronomer, and mathematician who made fundamental contributions to the sciences of motion , astronomy , and strength of materials and to the development of the scientific method. His formulation of circular inertia , the law of falling bodies , and parabolic trajectories marked the beginning of a fundamental change in the study of motion. His insistence that the book of nature was written in the language of mathematics changed natural philosophy from a verbal, qualitative account to a mathematical one in which experimentation became a recognized method for discovering the facts of nature. Finally, his discoveries with the telescope revolutionized astronomy and paved the way for the acceptance of the Copernican heliocentric system , but his advocacy of that system eventually resulted in an Inquisition process against him.

Science has a great impact on our lives. Without science, we won't be able to enjoy many things that make our modern world possible. Every year several discoveries and inventions took place and so the same way in that had given an edge to science and technology.
