Powers of Ten Classic video from Charles and Ray Eames (1977), narrated by Phillip Morrison. From the YouTube site: "Powers of Ten takes us on an adventure in magnitudes. Starting at a picnic by the lakeside in Chicago, this famous film transports us to the outer edges of the universe. Every ten seconds we view the starting point from ten times farther out until our own galaxy is visible only a s a speck of light among many others. Returning to Earth with breathtaking speed, we move inward- into the hand of the sleeping picnicker- with ten times more magnification every ten seconds. Our journey ends inside a proton of a carbon atom within a DNA molecule in a white blood cell."
Periodic Videos From the webpage: "Tables charting the chemical elements have been around since the 19th century - but this modern version has a short video about each one." Includes element 118!
Sixty Symbols Videos about the symbols of physics and astronomy.
Quantum Mechanics YouTube (52:50). The Fabric of the Cosmos: Quantum Leap - NOVA (2012).
Visualization of Quantum Physics YouTube (14:33). "This video visually demonstrates some basic quantum physics concepts using the simple case of a free particle."
Heisenberg's Uncertainty Principle Explained From the YouTube site: "Heisenberg's uncertainty principle tells us that it is impossible to simultaneously measure the position and momentum of a particle with infinite precision. In our everyday lives we virtually never come up against this limit, hence why it seems peculiar. In this experiment a laser is shone through a narrow slit onto a screen. As the slit is made narrower, the spot on the screen also becomes narrower. But at a certain point, the spot starts becoming wider. This is because the photons of light have been so localised at the slit that their horizontal momentum must become less well defined in order to satisfy Heisenberg's uncertainty principle." Veritasium video.
What is the Uncertainty Principle? MinutePhysics explanation of the uncertainty principle. Not bad for 63 seconds, but needs a bit more explanation.
Wave-Particle Duality Part I Part II From YouTube: "Minute Physics provides an energetic and entertaining view of old and new problems in physics -- all in a minute! In [part I], we discuss the Wave Particle Duality and why quantum mechanics is weirder than anything we're used to in our daily lives! In [part II], we revisit the wave particle duality and present an intuitive analogy for understanding how it works." Warning: some of this may be controversial!

Quantum Chromodynamics (QCD), other Standard Model

NameComments
Empty Space is NOT Empty From the YouTube site: "An atom is mostly empty space, but empty space is mostly not empty. The reason it looks empty is because electrons and photons don't interact with the stuff that is there, quark and gluon field fluctuations." Features Prof. Derek Leinweber of the University of Adelaide, a former postdoc in the OSU Nuclear Theory Group. Veritasium video (2013).
Visualizations of Quantum Chromodynamics (QCD) Webpage created by the Centre for the Subatomic Structure of Matter (CSSM) and Department of Physics, University of Adelaide with various visualizations of QCD. These include gluon fields in the vacuum, the "flux tube" between a quark-antiquark pair, and the composition of a proton.
Your Mass is NOT From the Higgs Boson From the YouTube site: "The Higgs mechanism is meant to account for the mass of everything, right? Well no, only the fundamental particles, which means that electrons derive their mass entirely from the Higgs interaction but protons and neutrons, made of quarks, do not. In fact the quark masses are so small that they only make up about 1% of the mass of the proton (and a similar fraction of the neutron). The rest of the mass comes from the energy in the gluon field. Gluons are massless, but there is so much energy in the field that by E=mc^2 there is a significant amount of mass there. This is where most of your mass comes from and the mass of virtually everything around you. Includes explanations by Prof. Derek Leinweber of the University of Adelaide, a former postdoc in the OSU Nuclear Theory Group. Veritasium video (2013).
Neutrino: Measuring the Unexpected [31 minutes] From the storyline: "In the new documentary short Neutrino: Measuring the Unexpected, directed by Javier Diez, a trio of renowned physicists take us on a guided tour through a series of groundbreaking experiments. Each of these studies is designed to uncover the true nature of the neutrino, and to provide answers to some of the grandest and most challenging questions that remain about our universe."
Violent Universe [180 minutes] From the storyline: "Take a breathtaking journey into the future, five billion years from now, to see the ultimate fate of the Solar System. This gem from HubbleCast showcases stunning Hubble imagery of the death throes of Sun-like stars. The wreckage of these dying stars form the building blocks of new generations of stars."
The Fabric of the Cosmos [240 minutes] From the storyline: "The Fabric of the Cosmos, a four-hour series based on the book by renowned physicist and author Brian Greene, takes us to the frontiers of physics to see how scientists are piecing together the most complete picture yet of space, time, and the universe."

Nuclear Physics overview

NameComments
Exploring the Heart of Matter This webpage has a long and short version of a video giving an overview of some of the key ideas from the decadal survey report NP2010 (released in 2012), called "Nuclear Physics: Exploring the Heart of Matter", which assessed the outlook for nuclear physics research in the United States. Watch the long version!
The valley of stability This YouTube video gives an excellent overview of the table of nuclides, including binding energy and types of radioactive decay, and connects this with nucleosynthesis. The discussion of the r-process happening in supernova is no longer the favored explanation (there is evidence the site of the r-process is colliding neutron stars!).

Relativistic Heavy-Ion (including RHIC and LHC)

See also the RHIC videos page.

NameComments
Breakthrough: RHIC Explores Matter at the Dawn of Time "Physicist Paul Sorensen describes discoveries made at the Relativistic Heavy Ion Collider (RHIC), a particle accelerator at the U.S. Department of Energy's Brookhaven National Laboratory. At RHIC, scientists from around the world study what the universe may have looked like in the first microseconds after its birth, helping us to understand more about why the physical world works the way it does -- from the smallest particles to the largest stars." (2012)
Hot Quark Soup Produced at RHIC YouTube (1:37). "The Relativistic Heavy Ion Collider (RHIC, http://www.bnl.gov/rhic ) is a 2.4-mile-circumference particle accelerator/collider that has been operating at Brookhaven Lab since 2000, delivering collisions of heavy ions, protons, and other particles to an international team of physicists investigating the basic structure and fundamental forces of matter. In 2005, RHIC physicists announced that the matter created in RHICs most energetic collisions behaves like a nearly perfect liquid in that it has extraordinarily low viscosity, or resistance to flow. Since then, the scientists have been taking a closer look at this remarkable form of matter, which last existed some 13 billion years ago, a mere fraction of a second after the Big Bang. Scientists have revelaed new findings, including the first measurement of temperature very early in the collision events, and their implications for the nature of this early-universe matter." (2010)
RHIC: The Perfect Liquid YouTube (1:20). "Evidence to date suggests that gold-gold collisions the Relativistic Heavy Ion Collider at Brookhaven are indeed creating a new state of hot, dense matter, but one quite different and even more remarkable than had been predicted. Instead of behaving like a gas of free quarks and gluons, as was expected, the matter created in RHIC's heavy ion collisions appears to be more like a "perfect" liquid." (2008)
Hydrodynamic simulations of relativistic heavy ion collisions at RHIC and LHC YouTube (1:39). "In the following video, you will watch the evolution of energy density and flow velocity in Au+Au collisions at 200A GeV at RHIC and Pb+Pb collisions at 2.76A TeV at LHC." By Chun Shen, OSU graduate student in Physics.
