→ Sir Isaac Newton was knighted by Queen Anne in 1705. He died as a bachelor at the age of 85.
→ His modesty is reflected in one of his remarks at his deathbed, "If I have seen farther than others, it is by standing on the shoulders of the giants."
→ Once while sitting under an apple tree in his home garden, it is said, a ripe apple fell on his head. The question, as to why an apple should fall towards earth, finally led him to postulate the famous theory about the law of universal gravitation. Newton was able to explain the motion of planets, flow of tides and special features of the motion of earth and moon.
