If the case is you professor is a hard-core Newton fan, and quite the otherwise for Einstein, you should include a story about Newton's great charachter and kindness, as well has his achievements and theories. I don't remember the story well, but back at Newton's time there were these two physicists, regarded has best in their field, with cutting edge work. He discovered a new light and color theory, radically different than their work, the orthodox belief. He waited until they died, and then presented the theory. He didn't want people to laugh at them and them to feel bad, and stuff like that, apparently.
Sir Isaac Newton was born, 25 December 1642 – 20 March 1727 by the Julian calendar in use in England at the time, or 4 January 1643 – 31 March 1727 by the current international Gregorian calendar. He was an English physicist, mathematician, astronomer, philosopher, and alchemist. Newton was the first to promulgate a set of natural laws that could govern both terrestrial motion and celestial motion. Newton is also credited with providing mathematical substantiation for Kepler's laws of planetary motion. He would expand these laws by arguing that orbits (such as those of comets) were not only elliptic, but could also be hyperbolic and parabolic. Newton is also notable for argueing that light is composed of particles. Later physicists instead favored a wave explanation of light to account for diffraction. Today's quantum mechanics recognizes a "wave-particle duality," particles are actually waves and particles; however today's quanta of light, photons bear very little remblance to Newton's "corpuscles." He was the first to realize that the spectrum of colors observed when white light passed through a prism was inherent in the white light and not added by the prism as Roger Bacon had claimed in the 13th century.
Newton also developed a law of cooling, describing the rate of cooling of objects when exposed to air; almost totally the binomial theorem; and the principles of angular and conservation of momentum. He studied the speed of sound in air, and made a theory of stellar origins.
