![]() I have often gone on record as saying that I was inspired to formulate my theory of gravitation by watching an apple fall from a tree. But you’re also remembered for the ‘apple incident.’ Is there any truth in that? Before the ‘natural sciences’ became recognised, people like me (although there weren’t very many to fall into that category) called ourselves ‘natural philosophers.’Į&T: You’re best known for your three physical laws that established the foundation for classical mechanics. So, if you wish to be correct, since I was born in the hamlet of Woolsthorpe-by-Colsterworth in the county of Lincolnshire, the term you should apply to my nationality is ‘English.’ Similarly, the word ‘scientist’ was never used in the way you mean it until the 19th century, when it was coined by William Whewell, Master of Trinity College, Cambridge – my old college in fact – where I started off as a subsizar (what 21st century folk would call ‘working your way through college’). I’m not entirely sure exactly what you mean by the word ‘Britain’ here, but if you are referring to the Kingdom of Great Britain, then that didn’t come into being until 1707, following the Acts of Union, which was towards the end of my terrestrial life. Sir Isaac Newton: There are factual and linguistic inaccuracies in the premise of your question, sir. In the 21st century you’re often hailed as ‘Britain’s greatest ever scientist.’ You’re shaking your head. Let’s get a few terms clear from the start. Its disruptive pattern applied Abbott Thayer’s theories in an effort to inhibit enemy observation from the air and on the ground.E&T: Good morning, Sir Isaac. The colorful pattern on this German aircraft from World War I is called lozenge camouflage. Although his suggestions were initially rejected, his former students were among the founders of the American Camouflage Society in 1916 and his theories were eventually adopted and are still used today. Despite these shortcomings, Thayer went on to be the first to propose camouflage for military purposes. Teddy Roosevelt most notably attacked his theories by pointing out that this concealment doesn’t last all season, or even all day, but was dependent on a single frozen moment in times. He was extreme in his views arguing that all animal coloration was for protective purposes and failing to recognize other possible reasons such as sexual selection – characteristics for attracting a mate. In his book, Concealing Coloration in the Animal Kingdom, Thayer presented his beliefs of protective coloration as an essential factor in evolution helping animals disguise themselves from predators. ![]() Thayer, an American artist, devoted much of his life to understanding how animals conceal themselves in nature for survival. In this illustration Thayer shows how a peacock can disappear into its surroundings. American artist Abbott Thayer introduced the concept of disruptive patterning, in which an animal’s uneven markings can disguise its outline. Illustrstions by Abbott Handerson Thayer (his father)Ĭoncealing-Coloration in the Animal KingdomĬan you find the animal hiding in this image? Camouflage uses color to conceal forms by creating optical illusions. Subtractive primary colors - blue, red, and yellow – are often taught to us as children, and when mixed together they create black. ![]() Books, paintings, grass and cars are examples of a subtractive color system which is based on the chemical makeup of an object and its reflection of light as a color. Red, green and blue are the primary additive colors and when combined they produce transparent white light. Rainbows, TVs, computer screens and mobile devices all emit light and are examples of an additive color system (the subject of Newton’s Opticks). Le Blon’s distinction marks the first documentation of what is now referred to as additive and subtractive color systems. ![]() He makes an important distinction between “material colors,” as used by painters, and colored light, which was the focus of Newton’s color theories. ![]() Le Blon was the first to outline a three-color printing method using primary colors (red, yellow, blue) to create secondary colors (green, purple, orange). This very rare book formed the foundation for modern color printing. Coloritto, or, The harmony of colouring in painting. ![]()
