“Sir Isaac Newton” was a scientist mathematician and astronomer. He was born on January 4, 1643, in Woolsthorpe, England. His father’s name was Isaac Newton SR and his mother’s name was Hannah Ayscough. His father was a farmer and had died three months before Newton’s birth his mother remarried when Isaac was three years old and left young Issac in the care of his grandparents.

Issac attended a school where he was an adequate student at one point his mother tried to take him out of gold so he could help on the farm, but Issac had no interest in becoming a farmer and was soon back at school. Newton attained his preliminary education from the King School in Grantham where he had sold and achieved the top rank. He then enrolled himself as a sizar at the Trinity College, Cambridge in 1661. The young Isaac Newton is sitting in his garden when an apple falls on his head and with any stroke of brilliant Insight he suddenly comes up with his theory of gravity he would spend much of his life at Cambridge becoming a professor of mathematics and a fellow of the Royal Society. He eventually was elected to represent Cambridge University, as a member of parliament Issac had to leave Cambridge from 1665 to 1667, because of the Great Plague. He spent these two years in study in isolation at his home in Woolsthorpe developing theories on calculus, Gravity, and the laws of motion. In 1696 Newton become the warden of the Royal Mint in London he took his duties seriously and tried to get rid of corruption as well to Reform the currency of England he was elected president of the Royal Society in 1703 and was knighted by Queen Anne in 1705. In 1687 Newton published his most important work called “The Philosophies Naturalis Principia Mathematica”. In this work, he describes the three laws of motion as well as the law of universal Gravity this work would go down as one of the most important works in the history of science. It not only introduced the theory of gravity but defined the principles of modern physics outlined in the Principia is a theory about gravity that helps to explain the movement of the planets and the sun this theory is known today as Newton’s law of universal gravitation. Newton’s laws of motion were three fundamental laws of physics that laid the foundation for classical mechanics Newton invented a wall new type of mathematics which he called”Fluxions”. Today we called Smart Calculus and it is an important type of math used in “Advanced Engineering and Science”. In 1658 Newton invented the reflecting telescope this type of telescope used to reflect light and form an image nearly all of the major telescopes used in Astronomy today are reflecting telescopes. He died on March 31st, 1727, in London England at the age of 84 “TWO EVERY ACTION THERE IS AN EQUAL AND OPPOSITE REACTION”.

“Alexander Graham Bell” he was the inventor of Telephone. He was born on March 3rd 1847 in Edinburg Scotland. His father’s name was Alexander melville Bell and mother’s name was Elisa grace. His father was a professor and mother was a painter and pianist. He had two brothers but both of whom died of Tuberculosis.

Throughout his childhood is spent short period of time in traditional educational institutions including Edinburghs Royal High School, which he left at the age of 15 he initially attended University of Edinburgh and then the university College London England but did not receive a formal education in 1817 after the death of two of his brother the bell family moved to Canada for the sake of his health expanding on his father work of teaching deaf people to communicate he began working on transmitting and telephonic messages in 1872 he founded School of “vocal physiology and mechanics of speech”in Boston where he taught elocution to his pupils in 1873 he was appointed the professor of vocal physiology and Elocution at the Boston University School of oratory. While pursuing his teaching profession he was drawn towards an idea of transmitting the human voice over wires. In 1874, he hired an assistant Thomas Watson is skilled electrician, who developed the tools and instruments he needed Jo continue the project on March 10 1876 he produced the first intelligible telephone call when he said Mr Watson come here I want to see you Thomas Watson who was in another room here Bells voice and it came to see the telephone had worked a legal battle ensued with inventors Elisha Gray, who claimed his invention of the predated Bell’s. But the court ruled in Bell’s favor and subsequently”Bell Telephone Company was formed in 1877.

On July 11,1877 he married his deaf student, Mabel Hubbard at the age of 30. They had four children, They are Elsie May Bell, Marian Hubbard Bell, Edward Bell, and Robert Bell. By 1883, he created the technology for the Graphophone and other early sound recording equipment in magnetic recording technology that was an early form of tape recording towards the end of the nineteenth century his interest began to move away sound transmission and recording to transport Technologies he developed a passion for air travel and helped to established the aerial experiment Association in 1907 in all he held 18 patents in his name alone and to all that he shared with collaborators among them telephone, Photo phone, Hydrofoil board, Audio meter, HD-4, Metal detector, Tetrahedral kite are noteworthy. He was one of the founders of the National Geographic society in 1888 and served as its president from 1896 to 1904 he died on August 2, 1922 in Beninn Bhreagh, Nova Scotia, at age of 75 due to complications from Diabetes “BEFORE ANYTHING ELSE , PREPARATION IS THE KEY TO SUCCESS”.
