As a Sizar, a student who received financial aid by working, he relied on his intelligence and resourcefulness.
Newton’s studies focused on mathematics and natural philosophy. He was influenced by the works of scholars like Descartes and Galileo.
After a brief closure of the university due to the Great Plague in 1665, he returned home, where he further explored his ideas on calculus and gravity. This creative period lasted two years, leading to significant insights that laid the groundwork for his later achievements.
Key Contributions and Theories
Isaac Newton made foundational contributions that shaped the understanding of gravity and the laws of motion. His work laid the groundwork for many areas of modern science, influencing physics, mathematics, and optics. Below are some of his key contributions, presented in detail.
Laws of Motion and Universal Gravitation
Newton formulated the three laws of motion, which describe how objects behave when forces act on them. These laws are:
- Inertia: An object in motion stays in motion unless acted upon.
- F=ma: The force acting on an object is equal to its mass times its acceleration.
- Action and Reaction: For every action, there is an equal and opposite reaction.
In his work Philosophiæ Naturalis Principia Mathematica, Newton introduced the law of universal gravitation. He proposed that every mass attracts every other mass, showing how the moon orbits Earth due to this force.
This connection between motion and gravity transformed scientific thought and laid the groundwork for Newtonian mechanics.
Development of Calculus
Newton’s development of calculus was vital for describing motion and changes in physical systems. He created methods to calculate rates of change and areas under curves.
This tool allowed scientists to better understand physics and mechanics.
Newton used calculus to formulate his laws of motion and gravitation. By providing a formal mathematical framework, he enabled future scientists to solve complex problems related to motion and forces.
This innovation significantly advanced mathematical principles in natural philosophy, enriching the field.
