Answer 2

$\huge {\bf{\red{\tt{Sir \:Isaac\: Newton}}}}$

$<bf><em><u><strong>Sir Isaac </strong><strong>Newton</strong></u></em> was born in </p><p></p><p>Woolsthorpe near Grantham, England. is </p><p></p><p>generally regarded as the most and He </p><p></p><p>original influential theorist in the history </p><p></p><p>of science. He was born in a poor </p><p></p><p>farming family. But he was not good at </p><p></p><p>farming. He was sent to studyat </p><p></p><p>Cambridge University in 1661. In 1665 a </p><p></p><p>plague broke out in Cambridge and so </p><p></p><p>Newton took a year off. It was during this </p><p></p><p>year that the incident of the apple falling </p><p></p><p>on him is said to have occurred. This </p><p></p><p>incident prompted Newton to explore the </p><p></p><p>possibility of connecting gravity with the </p><p></p><p>force that kept the moon in its orbit. This </p><p></p><p>led him to the universal law of </p><p></p><p>gravitation. Itis remarkable that many </p><p></p><p>great scientists before him knew </p><p></p><p>of gravity but failed to realise it. </bf>$

$<bf>Newton formulated the well-known laws of motion. He worked on theories of light and colour. Hedesigned anastronomical telescope to carry out astronomical observations. Newton was also a great mathematician. He invented anew branch of mathematics, called calculus. He used it to prove that for objects outside asphereofuniformdensity, the sphere behaves as if the whole of its mass is concentrated at its centre. Newton transformed the structure of physical science with his three laws of motion and the universal law of gravitation. As the keystone of the scientificrevolution of the seventeenth century, Newton's work combined the contributions of Copernicus, Kepler, Galileo, and others into a new powerful synthesis. </bf>$

$<bf>It is remarkable that though the gravitational theory could not be verified at that time, there was hardly any doubt about its correctness. This is because Newton based his theory on sound sclentific reasoning and backed it with mathematics. This made the theory simple and elegant. These qualities are howrecognised as essential requirements ofa good sclentific theory.</bf>$
