The Latin inscription on the base translates as:"Here is buried Isaac Newton, Knight, who by a strength of mind almost divine, and mathematical principles peculiarly his own, explored the course and figures of the planets, the paths of comets, the tides of the sea, the dissimilarities in rays of light, and, what no other scholar has previously imagined, the properties of the colours thus produced. Diligent, sagacious and faithful, in his expositions of nature, antiquity and the holy Scriptures, he vindicated by his philosophy the majesty of God mighty and good, and expressed the simplicity of the Gospel in his manners.

Title: Newtonian telescope
Content:   The Newtonian telescope, also called the Newtonian reflector or just the Newtonian, is a type of reflecting telescope invented by the English scientist Sir Isaac Newton (1642–1727), using a concave primary mirror and a flat diagonal secondary mirror. Newton's first reflecting telescope was completed in 1668 and is the earliest known functional reflecting telescope. The Newtonian telescope's simple design has made it very popular with amateur telescope makers.

Content:  relativity. Newton used his mathematical description of gravity to derive Kepler's laws of planetary motion, account for tides, the trajectories of comets, the precession of the equinoxes and other phenomena, eradicating doubt about the Solar System's heliocentricity. He demonstrated that the motion of objects on Earth and celestial bodies could be accounted for by the same principles. Newton's inference that the Earth is an oblate spheroid was later confirmed by the geodetic measurements of Maupertuis, La Condamine, and others, convincing most European scientists of the superiority of Newtonian mechanics over earlier systems. Newton built the first practical reflecting telescope and developed a sophisticated theory of colour based on the observation that a prism separates white light into the colours of the

Newton also constructed a primitive form of a frictional electrostatic generator, using a glass globe. In his book Opticks, Newton was the first to show a diagram using a prism as a beam expander, and also the use of multiple-prism arrays. Some 278 years after Newton's discussion, multiple-prism beam expanders became central to the development of narrow-linewidth tunable lasers. Also, the use of these prismatic beam expanders led to the multiple-prism dispersion theory. Subsequent to

He succeeded in explaining the colour of thin and of thick plates (diffraction), and the inflexion of light, and he wrote on double refraction, light polarisation and binocular vision. He also invented a reflecting quadrant for observing the angles between the moon and the fixed stars&mdash; the same in every essential as the historically important navigational instrument more commonly known as Hadley's quadrant. This discovery was communicated by him to Edmund Halley in 1700 but was not published, or communicated to the Royal Society, until after Newton's death, when a description of it was found among his papers.
Title: Annus mirabilis
Content:  In 1666 Isaac Newton, aged 23, made revolutionary inventions and discoveries in calculus, motion, optics and gravitation. It was in this year that Newton was alleged to have observed an apple falling from a tree, and in which he in any case hit upon the law of universal gravitation (Newton's apple). He was afforded the time to work on his theories due to the closure of Cambridge University by an outbreak of plague.

Many of these advancements continue to be the underpinnings of non-relativistic technologies in the modern world. He used the Latin word gravitas (weight) for the effect that would become known as gravity, and defined the law of universal gravitation. In the same work, Newton presented a calculus-like method of geometrical analysis using 'first and last ratios', gave the first analytical determination (based on Boyle's law) of the speed of sound in air, inferred the oblateness of Earth's spheroidal figure, accounted for the precession of the equinoxes as a result 
Title: History of physics
Content:  The late 17th and early 18th centuries saw the achievements of Cambridge University physicist and mathematician Sir Isaac Newton (1642-1727). Newton, a fellow of the Royal Society of England, combined his own discoveries in mechanics and astronomy to earlier ones to create a single system for describing the workings of the universe. Newton formulated three laws of motion which formulated the relationship between motion and objects and also the law of universal gravitation, the latter of which could be used to explain the behavior not only of falling bodies on the earth but also planets and other celestial bodies. To arrive at his results, Newton invented 
Title: Later life of Isaac Newton
Content:  Newton devoted much of his time to the study of chemistry. A great number of his experiments still remain in manuscript. His Tabula Quantilatum et Graduum Caloris contains a comparative scale of temperature from that of melting ice to that of a small kitchen fire. He wrote another chemical paper De Natura Acidorum. Sir Isaac spent much time in the study of the alchemists including Jacob Boehme. In an earlier part of his life, Newton and a relation Dr Newton of Grantham had put up furnaces and had wrought for several months in quest of the philosophers tincture. Sir Isaac also studied the manuscripts of Flamsteed's Explication of Hieroglyphic Figures and William Yworth's Processus Mysterii Magnii Magni Philosophicus. Scientists have discovered that before Isaac died he burned important papers in his fireplace and they think it might have been an important discovery he made while doing alchemy.

He mentioned four:  Newton criticized all the methods, pointing out their weak points, and it is due mainly to his evidence that the Committee brought in the report which was accepted by the House, and shortly afterwards was converted into a Bill, passed both Houses, and received the royal assent. The report ran "that it is the opinion of this committee that a reward be settled by Parliament upon such person or persons as shall discover a more certain and practicable method of ascertaining the longitude than any yet in practice; and the said reward be proportioned to the degree of exactness to which the said method shall reach."
