American theoretical physicist (1918-1988) whose work in quantum electrodynamics earned him the Nobel Prize in Physics in 1965; he is often credited for introducing the concept of nanotechnology. Incredible unsigned mathematical manuscript by Nobel Prize-winning physicist Richard Feynman, penned carefully in red ballpoint on both sides of an off-white 5.75 x 8.25 sheet. The manuscript illustrates how a computer program can approximate a solution to a differential equation using Runge-Kutta methods, with Feynman also incorporating a sequence of computer commands and writing the surnames "Janhke Emde," a reference to German mathematician Eugene Jahnke and German electrical engineer Fritz Emde. In fine condition. Developed around 1900 by German mathematicians Carl Runge and Martin Kutta, the Runge-Kutta methods are a group of iterative methods that include the Euler Method, a routine devised by Swiss mathematician Leonhard Euler, to arrive at approximate solutions of ordinary differential equations. A magnificent opportunity to own a handwritten manuscript from one of physic's most brilliant minds. Provenance: Sotheby's, Property from the Family of Richard P.
