![]() ![]() As an adult, he spoke with a New York accent strong enough to be perceived as an affectation or exaggeration, so much so that his friends Wolfgang Pauli and Hans Bethe once commented that Feynman spoke like a "bum". Feynman was a late talker and did not speak until after his third birthday. She trained as a primary school teacher but married Melville in 1917, before taking up a profession. Lucille's father had emigrated from Poland, and her mother also came from a family of Polish immigrants. Feynman's mother was born in the United States into a Jewish family. ![]() Feynman's father was born into a Jewish family in Minsk, Belarus (then part of the Russian Empire) and emigrated with his parents to the United States at the age of five. Feynman! and What Do You Care What Other People Think?, and books written about him such as Tuva or Bust! by Ralph Leighton and the biography Genius: The Life and Science of Richard Feynman by James Gleick.įeynman was born on May 11, 1918, in Queens, New York City, to Lucille ( née Phillips 1895–1981), a homemaker, and Melville Arthur Feynman (1890–1946), a sales manager. Feynman also became known through his autobiographical books Surely You're Joking, Mr. ![]() Tolman professorship in theoretical physics at the California Institute of Technology.įeynman was a keen popularizer of physics through both books and lectures, including a 1959 talk on top-down nanotechnology called There's Plenty of Room at the Bottom and the three-volume publication of his undergraduate lectures, The Feynman Lectures on Physics. Along with his work in theoretical physics, Feynman has been credited with pioneering the field of quantum computing and introducing the concept of nanotechnology. ![]() He assisted in the development of the atomic bomb during World War II and became known to a wide public in the 1980s as a member of the Rogers Commission, the panel that investigated the Space Shuttle Challenger disaster. In a 1999 poll of 130 leading physicists worldwide by the British journal Physics World, he was ranked the seventh-greatest physicist of all time. During his lifetime, Feynman became one of the best-known scientists in the world. For his contributions to the development of quantum electrodynamics, Feynman received the Nobel Prize in Physics in 1965 jointly with Julian Schwinger and Shin'ichirō Tomonaga.įeynman developed a widely used pictorial representation scheme for the mathematical expressions describing the behavior of subatomic particles, which later became known as Feynman diagrams. Therefore, kinetic energy will be 12500 joules.Richard Phillips Feynman ( / ˈ f aɪ n m ə n/ – February 15, 1988) was an American theoretical physicist, known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics, the physics of the superfluidity of supercooled liquid helium, as well as his work in particle physics for which he proposed the parton model. Q.1: A car is traveling with a velocity of 10 m/s and it has a mass of 250 Kg. You can download Basic Physics Formula Cheat Sheet by clicking on the download button below Ohms law says that the current running through some conductor material is directly proportional to the potential difference between two endpoints of the conductor.Įlectric current flowing through the conductor in amperes.įrequency is the revolutions completed per second or as the number of wave cycles. The velocity with which the body is traveling Kinetic energy is the energy that is possessed by a body due to its state of motion. The pressure is defined as the amount of force applied per unit area of the object. Weight is not anything but the force which an object experiences due to gravity. The Energy spent to do work in a unit amount of time is termed as Power. The capacity to do some work is termed as Energy. The density of material shows the denseness of it in a specific given area.Īccording to Newton’s second law of motion, the force can be expressed by the product of mass and acceleration of the body. The average speed is the average of speed of a moving body for the overall distance that it has covered.Īcceleration is defined as the rate of change in velocity to the change in time. Some basic but very important Physics formula is given below: 1) Average Speed Formula: ![]()
