Sir Isaac Newton explained the workings of the universe through his laws of motion and gravitation. He used three laws to explain the way objects move when an unbalanced force acts on them. These are called Newton’s law. The first law which is known as Inertia, states that an object in rest will remain still and an object in motion stays at a steady pace unless acted upon by a force. The second law stated the relationship between acceleration and applied force which is expressed in the form F=ma. While the third and final law stated that ‘for every action there is a equal and opposite reaction.’ Isaac Newton’s most important contributions were that involving science and mathematics. Newton discovered many of the laws and theories that enabled us to further our understanding of the universe, but also allowed scientists in the future to use these tools to discover how to enter space. Newton built the first reflecting telescope and changed the way we think about light and colour as he developed a theory that colours were a characteristic of light. These scientific discoveries have contributed to important discoveries in today’s society. These are the introduction of milled edges and detailed designs on coins making it impossible for people to forge coins and clip the silver from the edges. Another contribution which has heavily impacted today’s society is the seat belt which is based on the first law and provides safety for passengers traveling in motion. The seat belt is the unbalanced force that brings the passage from a state of motion to a state of rest. This discovery based on Newton’s laws has saved lives and has heavily impacted today’s Society

Galileo Galilee is best known for his laws of motion. From an early age he invented important instruments in order to conduct accurate tests. These include the thermometer, used to measure temperature, and the astronomical telescope which he expanded his invention from the basic telescope. He developed the theory...
