The 40 Smartest People of All Time


When it comes to determining smarts, there are many different approaches. IQ tests have long been the standard for measuring intelligence, but the IQ score misses out on other important markers of success. American electrochemical engineer Libb Thims devised a unique method to rank the smartest people in history. Thims started with a list of people who had IQ scores of more than 200. Thims then ranked people according to whether they had a specific area of focus that suggested a level of genius. Later, Thims ranked everybody who had a strong aptitude, marked capacity, or heightened inclination in some area that coupled with their IQ would make them worthy of the title genius. The final result yielded this quirky list of very smart people.

33. Gottfried Leibniz

17th century philosopher and logician Gottfried Leibniz was one of the great Rationalists. He invented differential and integral calculus. Leibniz also developed a system of infinitesimal calculus, which he figured out independently of Sir Isaac Newton. Leibniz was able to make a clearer system of calculus, and his notation and writing of calculus is still the accepted form today.  Leibniz also worked on the invention of the calculating machine. To do this, he developed the binary number system, which uses base 2 counting with only 0 and 1. Although he acknowledged that the idea behind it dated to the I Ching, Leibniz’s usage of binary numbering wasn early predicate for the computer. Indeed, nearly every modern computer system begins with the ability of binary to be represented by on/off, 0 or 1.

(The first belongs to Isaac Newton). Maxwell was able to determine that magnetic fields and electric fields move through space as waves, which travel at the speed of light. His theories eventually led to the development of radio waves. Einstein once said he stood on Maxwell’s shoulders.
