    Richard Feynman The World from another point of view HD


    The famous American physicist Richard Feynman used to take holidays in England. His third wife, Gweneth Howarth, was a native of West Yorkshire, so every year the Feynman family would visit her hometown of Ripponden or the nearby hamlet of Mill Bank.

    In 1973 Yorkshire public television made a short film of the Nobel laureate while he was there. The resulting film, Take the World From Another Point of View, was broadcast in America as part of the PBS Nova series. The documentary features a fascinating interview, but what sets it apart from other films on Feynman is the inclusion of a lively conversation he had with the eminent British astrophysicist Fred Hoyle.

    Great Minds: Richard Feynman - The Uncertainty Of Knowledge


    ... Great Minds, Great Words: Richard Feynman - The Uncertainty of Knowledge ... The Nature and Purpose of the Universe.

    Playlist Great Minds, Great Words:

    Please SUBSCRIBE to Science & Reason:


    Richard Feynman (1918-1988) was an American physicist known for his work in the path integral formulation of quantum mechanics, the theory of quantum electrodynamics and the physics of the superfluidity of supercooled liquid helium, as well as in particle physics (he proposed the parton model).

    For his contributions to the development of quantum electrodynamics, Feynman, jointly with Julian Schwinger and Sin-Itiro Tomonaga, received the Nobel Prize in Physics in 1965. He developed a widely used pictorial representation scheme for the mathematical expressions governing the behavior of subatomic particles, which later became known as Feynman diagrams. During his lifetime, Feynman became one of the best-known scientists in the world.

    He assisted in the development of the atomic bomb and was a member of the panel that investigated the Space Shuttle Challenger disaster. In addition to his work in theoretical physics, Feynman has been credited with pioneering the field of quantum computing, and introducing the concept of nanotechnology (creation of devices at the molecular scale). He held the Richard Chace Tolman professorship in theoretical physics at the California Institute of Technology.

    Feynman was a keen popularizer of physics through both books and lectures, notably a 1959 talk on top-down nanotechnology called There's Plenty of Room at the Bottom and The Feynman Lectures on Physics. Feynman also became known through his semi-autobiographical books (Surely You're Joking, Mr. Feynman! and What Do You Care What Other People Think?) and books written about him, such as Tuva or Bust!

    He was regarded as an eccentric and free spirit. He was a prankster, juggler, safecracker, proud amateur painter, and bongo player. He liked to pursue a variety of seemingly unrelated interests, such as art, percussion, Maya hieroglyphs, and lock picking.

    Feynman also had a deep interest in biology, and was a friend of the geneticist and microbiologist Esther Lederberg, who developed replica plating and discovered bacteriophage lambda. They had several mutual physicist friends who, after beginning their careers in nuclear research, moved for moral reasons into genetics, among them Leó Szilárd, Guido Pontecorvo, and Aaron Novick.

    The Feynman Technique


    Richard Feynman was a physicist who received a nobel prize for his work in quantum electrodynamics. He was notorious for asking his mathematicians to explain concepts in simple language to test their understanding.

    Here his unique technique to learn new materials:

    Step 1. Choose a topic you want to understand and start studying it. Once you know what it is about, take a piece of paper and write the topic at the top of the page.

    Step 2. Pretend you’re teaching the idea to someone else. Write out an explanation on the paper while you describe them out loud. Like this you get an idea of what you understand and where you still have gaps. Whenever you get stuck, go back and study. Repeat that process until you can explain it.

    Step 3. Finally do it again, but now simplify your language or use an analogy to make the point. If your explanation ends up wordy and confusing, that’s an indication that you do not understand the idea well enough. If that happens go back until you have mastered it.

    It is the process of thinking about an idea while teaching it that make the method so effective. Once you can explain an idea with simple language and create graphic analogies, you have deeply understood it and will remember it for a long time.

    Richard Feynman on What It Means | Blank on Blank | PBS Digital Studios


    The key was somehow to know what was important and what was not important, what was exciting, because I can’t learn everything. - Richard Feynman in 1966

    Hear more interview outtakes and learn more about Richard Feynman

    If you don’t really have a head for math and science, physics may be the most intimidating subject of them all. It’s space and time, the make-up of the entire universe - incredibly abstract and mind-bending stuff, and enough to make a lot of students throw in the towel. And that’s where Professor Richard Feynman really made his mark - of course he did all kinds of groundbreaking work, like his theory of quantum electrodynamics…. he proposed the parton model in the field of particle physics… was even part of the atomic bomb project.

    But he was also an amazing teacher, this dynamic and charismatic lecturer who made physics fun. He was one of those rare people who not only naturally understood math and science - he was actually able to make other people understand it too. And like it.

    Starting in 1966, science historian Charles Weiner interviewed Richard Feynman as part of a big oral history project at the American Institute of Physics. Recording hours of conversation, Weiner captured the details of Feynman’s entire career, his whole life. In those hours, Feynman talked about his earliest memories - what and who shaped the world-famous physicist - and teacher he’d later become. And most influential of all…. a man who was neither a scientist nor a mathematician - a man who didn’t even have any formal education - his dad.

    As part of our special series, The Experimenters -- uncovering interviews with the icons of science, technology, and innovation -- we found this interview with Feynman in the archives of the American Institute of Physics.

    Richard Feynmans Story of Particle Physics


    A 40 minute audio recording, restored with visual aids and diagrams, given by the legendary physicist and educator Richard Feynman on the history and development of the search for the fundamental structure of matter, from atomic physics to elementary particle physics.

    I personally restored this audio and produced the video for anyone with an interest, or even just a mild curiosity, in the world of particle physics and what scientific discoveries has happened, and continues to happen, at particle accelerator facilities such as at Fermilab, SLAC and of course CERN. This is a good lecture for anyone who wants a relatively quick but concise lecture from one of the grand masters of the field of physics.

    The story of how humanity's knowledge of matter, from the Periodic Table to the Standard Model of Particle Physics, developed is a very interesting one and shows that once we think we have found simplicity in physics, more complicated and unexpected phenomena and patterns occur again at a deeper level as nature does not give up its secrets so easily and never seems to let us get too complacent in our assumed mastery of a particular field. This has of course generated more and more discoveries and technological breakthroughs in their wake, accelerating our knowledge of matter and energy and increasing our power to manipulate it.

    Richard Feynman - Problem Solving


    Richard Feynman was one of the greatest problem solvers of the 20th century and loved being puzzled and solving puzzles, a quality that made him a legendary physicist. To be good at science is to be good at being puzzled and seeing puzzles in everyday phenomena that are taken for granted, allowing you to see what is right in front of you in a new and exciting point of view. This allows for huge developments and innovations that are completely different from anything before.

    One of the 3 winners of the 1965 Nobel prize in Physics for his work, Feynman is was an expert on quantum mechanics and developed the Path Integral formulation of Relativistic Quantum mechanics, used in Quantum Field Theory, interpreted the Born series of scattering amplitudes as vertices and Green's function propagators in his famous diagrams, the Feynman Diagrams, and also worked on the fundamental excitations in Liquid Helium leading to a correct model describing superfluidity using phonons, maxons and rotons to describe the various excitation curves.

    During the Manhatten Project, Richard Feynman performed theoretical calculations on the first nuclear weapons developed during the Manhatten project with his supervisor Hans Bethe. They extended Serber's original formula for the yield of a nuclear weapon and developed the Bethe-Feynman formula, which is still classified by the US government even today.

    Other fields of work include the Wheeler-Feynman Absorber Theory for Electromagnetic Radiation, developed with his colleague John A. Wheeler, which was the first attempt to create a theory of electromagnetism that obeys time-reversal theory.

    He also developed the Feynman-Hellmann Theorem, which can be formulated from his own Path Intregral interpretation and relate the derivative of the total energy of any system to the expectation value of the derivative of the Hamiltonian with respect to a single parameter, e.g volume.

    This theory makes possible the calculation of the intramolecular forces of individual molecule in terms of the electronic density (ρ(r)) and the atomic coordinates and nuclear charges of the individual atoms. This, simulated on computers, allows dynamical molecular and quantum systems to be simulated on powerful computers. Such technology is only beginning to have applications in the fields of simulating how proteins fold, how to design drugs that act specifically on biochemical processes and how to simulate quantum logic and computation, something Feynman had predicted long before before the first atomic traps were invented.

    Feynman was also a huge visionary in the fields of nanotechnology and small scale manufacturing, something which has led to the modern age and continues to accelerate to new developments in human civilization today.

    Richard Feynman Computer Heuristics Lecture


    Introduction Article to Heuristics and Metaheuristics -
    Richard Feynman, Winner of the 1965 Nobel Prize in Physics, gives us an insightful lecture about computer heuristics: how computers work, how they file information, how they handle data, how they use their information in allocated processing in a finite amount of time to solve problems and how they actually compute values of interest to human beings. These topics are essential in the study of what processes reduce the amount of work done in solving a particular problem in computers, giving them speeds of solving problems that can outmatch humans in certain fields but which have not yet reached the complexity of human driven intelligence. The question if human thought is a series of fixed processes that could be, in principle, imitated by a computer is a major theme of this lecture and, in Feynman's trademark style of teaching, gives us clear and yet very powerful answers for this field which has gone on to consume so much of our lives today.

    No doubt this lecture will be of crucial interest to anyone who has ever wondered about the process of human or machine thinking and if a synthesis between the two can be made without violating logic.

    Richard Feynman Tiny Machines Nanotechnology Lecture


    Richard Feynman gave his famous talk There's Plenty of Room at the Bottom (Original Transcript Available Here : on December 29th 1959 at the annual meeting of the American Physical Society at the California Institute of Technology (Caltech) as his vision on how physics and engineering could move in the direction that could eventually create nanotechnology.

    Really good ideas and strokes of genius are often manifest in the right questions being asked: How small can information be encoded? How can information be written? How can information it be read? All of these important Hows were asked by Feynman in a time when computers had to be put in large rooms and when the impending space race was forcing engineers to do some serious strategic thinking in making technology small enough to be lifted by rockets into space to function as serious tools in scientific exploration and defence.

    Feynman himself may not have invented the technology we see in the development and continuity of the computer age, but the fact that even in the early 1960's nanotechnology was being considered as a serious field of study was definitely a factor contributing to the boom in computer technology seen in the late 20th century and continues to reach more spectacular levels of sophistication in the 21st century.

    Jump 25 years forward into the year 1984, when Feynman tries to retell his 1959 lecture from a more modern perspective in that many aspects of his vision have been fulfilled, particularly with the invention of the electron microscope, the atomic force microscope and experimental manipulation of the atomic scale of matter. Also discussed is the current practical field of photolithography for the manufacture of bipolar transistors and junctions used in computer chips done on an industrial scale and how this process continues with ever decreasing wavelength capabilities of lasers from UV to X-rays. Feynman also discusses the boundaries of miniaturization and how the scale differences affect the function of certain aspects of technology as well as in nature.

    In the true spirit of Feynman, the discussion goes into the colorful details and gives diagrammatic examples of how this field had progressed from 1959 to 1984. We can only imagine how Feynman would have felt about the modern developments in nanotechnology in the 21st century where entirely exotic principles of physics may begin to become technologically significant, including vacuum fluctuations and quantum entanglements. Without a doubt he would have found our developments exciting but always within the realms of understanding by studying the most fundamental language of nature, quantum mechanics, to bring our macroscopic brains into visualizing, however abstractly, the tiny machinery of nature.

    Richard Feynman on Getting Arrested by Los Alamos Fence Security - Funny Clip!


    The famous physicist Richard P. Feynman always loved to test complex systems in the spirit of curiosity and fun and nowhere was this more true than in the security systems of the most complex scientific project in history, the Manhattan Project, where the greatest scientists of the age were gathered to create the first atomic bomb and in the process develop much of the scientific underpinnings of our modern civilization.

    Feynman, being Feynman, found that the best way to challenge the rigor of the establishment was with good old-fashioned mischief. He earned fame (or infamy) inside the safes of Los Alamos, cracking them with ease and leaving cryptic messages pretending to be a spy (all while real Soviet spies were inside and really learning the new nuclear secrets!) - hence his seemingly bizarre mischief making was indeed prophetic in many ways.

    Here, Richard Feynman talks briefly about how he tested fence security simply by taking the path of least action - through the holes in the fence! Funny stuff straight from the legendary man's mouth! Enjoy!

    Murray Gell-Mann talks about Richard Feynman


    In this interview, Murray Gell-Mann talks about his experience of working along with Richard Feynman in Caltech. A good insight into the two clashing personalities of the two great men, both equal in intelligence, but very different in mannerisms and image.

    Winner of the 1969 Nobel Prize in Physics for his unique classification of elementary particles into his meson and baryon groups, for which he called his Eight fold ways, Murray Gell-Mann led to development of the quark model using his concept of strangeness and isospin in the the Gell-Mann--Nishijima formula which was proven correct with the discovery of the Omega Minus baryon, which contained 3 strange quarks in his model.

    The quark model allowed for the appearance of particles with the same spin in the same quantum state, as long as they have different color charge which led to development of Quantum Chromodynamics, using the Dirac Lagrangian for SU(3) fields, represented by the Gell-Mann Matrices, QCD describes nonabelian vector fields which would later describe the color confinement and asymptotic feedom of QCD. This is similar to Feynman's use of the Dirac Lagrangian applied to SU(2) fields represented by the Dirac Matrices which describe abelian scalar fields and contain the electron propogator, mass and interaction terms which are invarient under gauge transformation when a field is introduced that transforms like an electromagnetic field, hence creating the photon propogator. Feynman's diagrams stem from these terms, and these apply for Quantum Chromodynamics as they do for Quantum electrodynamics, except requiring gluons instead of photons.

    Richard Feynman shared the 1965 Nobel prize in Physics for his work on QED with Julian Schwinger and Sin-Itiro Tomonaga, which triggered the modern view of particle physics: The Standard Model of Particle Physics.
    The inclusion of Gell-Mann's work into the Standard Model would define particle physics up untill the present day, the QCD Lagrangian describes the essential features of quark confinement which result in the Strong Force induced jets of mesons and baryons from quark-antiquark pair production seen in particle accelerators.

    Richard Feynman - Patents


    Richard Feynman talks about some of his unusual patents and how they came into being through some of his own ideas for possible.nuclear powered vehicles, which he brainstormed during his time working on the atomic bomb in The Manhattan Project.
    Feynman himself had no idea they would patent these ideas and only found out about it when he was offered a job of being the head of a research team to develop a nuclear powered aircraft. Feynman did not accept this job, as he was a theoretical physicist and aircraft engineering was of no interest to him.

    For legal reasons, a dollar was to be exchanged for the patent papers. Since Feynman received no dollar, he went to the patent office to get his dollar and used it to buy sweets as a joke to the bureaucratic and anal nature of patent law and the goons who enforce it.
