A Science Odyssey 'That's My Theory'
Isaac Newton


My real name is Sir Isaac Newton. I am credited with developing the theory of universal gravitation. I am also known for my work in optics, for devising a branch of mathematics called calculus, and for my laws of motion. All of this occured, by the way, between 1643 and 1727, during my time on Earth.

And I would also like to make it clear that I am in no way affiliated with any type of sugared, confectionary, or otherwise fig-filled cookie, and, contrary to any rumors you may have heard, my hair has never touched a curling iron or felt the heat of a hair dryer.
