**Early Life **
Isaac Newton was born on the 4 of January, 1727, in Lincolnshire, England and he died on the 20th of March, 1727. Unfortauly his father( who was also called Isaac Newton) was a farmer and died three months before his son was born. When he was three years old his mother, [|Hannah Ayscough], met a man called Reverend Barnabus Smith, and went to go live with him and left Isaac with his gradmother Margery Ayscough. The young Isaac disliked his stepfather and his mother for marrying him, as revealed by this entry in a list of sins committed up to the age of 19: "Threatening my father and mother Smith to burn them and the house over them." While Newton was once engaged in his late teens to a Miss Storey, he never married, being highly engrossed in his studies and work. Then Isaac Newton became an English physicist, mathematician, astronomer, natural philosopher, alchemist and theologian. toc

**The Three Laws of Motion ** He published a book called " Mathematictal princibles of Nature Philosophy" in 1687. Isaac Newton uncovered the three laws of motion, Law 1 " Every object in a state of uniform motion tends to remain in that state of motion unless an external force is applied to it", law 2 " The relationship between an object's mass m, its acceleration a, and the applied force F is F = ma. Acceleration and force are vectors (as indicated by their symbols being displayed in slant bold font); in this law the direction of the force vector is the same as the direction of the acceleration vector" and law 3 " every action has an equal and oppisite reaction".

**Medical Problem**  In the last few years of Newton´s life, he was troubled by urinary incontinence probably due to a Kidny stone. In january 1725 he seized a violent coughand inflarmmation of the lungs which induced him to move to Kensington. In the next month he had caused of gout and then had an improvement of health.

**Conclusion **  Newton built the first reflecting practical telescope and delevoped a theory of colour based on the observation that a prism decompoeses white light into the many colours that form the visible spectrum.  People say that Newton was resting under a apple tree and suddently an apple fell. He was thinking "Why didn´t the apple go up insteed of down?" and other questions, that is who he uncovered graity and the laws of motion.
