Particle physics (also high energy physics) is the branch of physics that studies the nature of the particles that constitute matter (particles with mass) and radiation (massless particles). Although the word "particle" can refer to various types of very small objects (e.g. protons, gas particles, or even household dust), "particle physics" usually investigates the irreducibly smallest detectable particles and the irreducibly fundamental force fields necessary to explain them. By our current understanding, these elementary particles are excitations of the quantum fields that also govern their interactions. The currently dominant theory explaining these fundamental particles and fields, along with their dynamics, is called the Standard Model. Thus, modern particle physics generally investigates the Standard Model and its various possible extensions, e.g. to the newest "known" particle, the Higgs boson, or even to the oldest known force field, gravity.
Modern particle physics research is focused on subatomic particles, including atomic constituents such as electrons, protons, and neutrons (protons and neutrons are composite particles called baryons, made of quarks), produced by radioactive and scattering processes, such as photons, neutrinos, and muons, as well as a wide range of exotic particles. Dynamics of particles is also governed by quantum mechanics; they exhibit wave–particle duality, displaying particle-like behaviour under certain experimental conditions and wave-like behaviour in others. In more technical terms, they are described by quantum state vectors in a Hilbert space, which is also treated in quantum field theory. Following the convention of particle physicists, the term elementary particles is applied to those particles that are, according to current understanding, presumed to be indivisible and not composed of other particles.
Richard Phillips Feynman, (/ˈfaɪnmən/; May 11, 1918 – 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, and the physics of the superfluidity of supercooled liquid helium, as well as in particle physics for which 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. In a 1999 poll of 130 leading physicists worldwide by the British journal Physics World he was ranked as one of the ten greatest physicists of all time.
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 addition to his work in theoretical physics, Feynman has been credited with pioneering the field of quantum computing, and introducing the concept of nanotechnology. He held the Richard C. Tolman professorship in theoretical physics at the California Institute of Technology.

Professor Brian Cox of the University of Manchester presents an educational walk, through the fundamentals of Particle Physics. Disclaimer: The copyright owner provides this content for educational purposes.
Part 1 of a series: covering introduction to Quantum Field Theory, creation and annihilation operators, fields and particles.
A lecture on the development of science of the standard model of high energy particle physics given to some of the CERN faculty for a demonstration of how this kind of complex science should be lectured to those with any level of science/physics background from laypeople to experts who want to keep up with current discoveries outside their field. Professor Brian Cox of Manchester University and contributor to the LHC's ATLAS and LHCb experiments, is one of the best public educators of physics of our time. He has a huge charisma and character to keep an audience's attention to fundamental topics in physics, keeping the sense of wonder but always keeping the real core of the subject intact - which is genuinely hard to do as in the process of teaching a subject like physics either the wonder...

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...
(October 12, 2009) Leonard Susskind gives the first lecture of a three-quarter sequence of courses that will explore the new revolutions in particle physics. In this lecture he explores light, particles and quantum field theory. Leonard Susskind, Felix Bloch Professor of Physics, received a PhD from Cornell University and has taught at Stanford since 1979. He has won both the Pregel Award from the New York Academy of Science and the J.J. Sakurai Prize in theoretical particle physics. He is also a member of the National Academy of Sciences.

According to the Standard Model of Physics a proton should never decay, but what would happen if it did? Read More: How the death of one tiny particle could end the universe http://io9.com/5958012/how-one-tiny-particle-could-end-the-universe “No one has observed any evidence for proton decay. That might be disappointing professionally for physicists, but it's good news for the universe. If it turns out to be possible, proton decay could be the beginning of the end of everything.” ____________________ DNews is dedicated to satisfying your curiosity and to bringing you mind-bending stories & perspectives you won't find anywhere else!

About the Presenter: After getting his Ph.D. in physics from UC San Diego, Garrett moved to Maui, seeking an optimum balance between surfing and his theoretical research. While pursuing an unanswered question at the heart of Quantum Field Theory, he began to develop what he called "An Exceptionally Simple Theory of Everything," which proposed a unified field theory combining particle physics and Albert Einstein's theory of gravitation. His story and work have been featured at TED, in Outside Magazine, The New Yorker, Surfer, and recently in Scientific American. #FQXiVideoContest2014 About TEDx In the spirit of ideas worth spreading, TEDx is a program of local, self-organized events that bring people together to share a TED-like experience.

An educational video I made for physics class on particle superposition. I also cover wave-particle duality, the Uncertainty Principle, and Schrödinger's Cat. All filming was done by SwooceTV, a friend of mine. Although there are a couple little memes scattered in here, its main purpose is to educate, so don't expect it to be hilarious.

Stockholm-based director Henric Hemmerlind talks about his latest film, a collaboration with choreographer Sacha Jean-Baptiste: “My friend, composer Eric Reid, who scored this piece, shared with me a dream where he had imagined what it was like to be a subatomic particle. This song reflects the type of movement and communication that he felt. He said there was a notable connection between emotion and communication with the bunch—i.e. all the other particles. One individual feeling had direct impact upon the overall fluidity of communication and action within the whole."
