In 1672, Isaac Newton launched the modern concepts of light and color by publishing his series of experiments. He showed that light consists of not one color but several.Continue Reading
Prior to Newton’s publication, people thought color was a mixture of light and darkness, and that prisms colored light. Robert Hooke believed this color theory and had a scale that ranged from brilliant
red--which is pure white light with the least amount of darkness added--to dull blue, the last step before black, which is the complete elimination of light by darkness.
Through his experiments, Newton discovered this theory was false. In one experiment, he set up a prism by a window and projected a 22-foot spectrum of red, orange, yellow, green, blue and violet onto a far wall. To show that prisms do not color light, he refracted the lights back into a single white light.
Artists were excited by Newton’s clear demonstration that all colors come from light alone. Most useful to theme is his color wheel, which enhances the effects of primary colors by placing them opposite their complementary colors.
No one questioned Newton’s ideas about light and color until 1810, when Johann Wolfgang von Goethe published a 1,400-page treatise on color. Although Goethe misinterpreted some of Newton’s experiments and created a distorted color wheel, he correctly concluded that there is more to human vision than light bouncing off objects and entering people’s eyes. Perception affects human vision. What people see depends upon the object, the lighting and perception.Learn more about Electricity
Isaac Newton became famous for his numerous contributions to science and mathematics, most notably his discovery and outlining of the laws of motion in physics and the invention of calculus in mathematics. Newton published various works that became well known among scholars during his lifetime, and his influence continued to remain significant centuries after his death.Full Answer >
There are many weird facts about Isaac Newton, who was unique right from the start. Three months before he was born, his father died. Then, Newton was born prematurely and not expected to survive. He held on, but at the age of three, his mother remarried and left Newton to live with his grandmother.Full Answer >

Isaac Newton did not invent the device known as Newton’s Balls. According to "The New York Times," it was invented by actor Simon Prebble in 1967. It is named for Newton because it demonstrates conservation of momentum and kinetic energy as described in Newton’s second law of motion.Full Answer >
