Do Photons Cast Shadows?
This video is about two-photon (gamma-gamma) physics, and how photons can interact with each other - either mediated by a passing lepton, or gravitationally via lensing, or via vacuum fluctuation pair production of vertical particles...

TED-Ed: How does an atom-smashing particle accelerator work? - Don Lincoln
An atom smasher, or particle accelerator, collides atomic nuclei together at extremely high energies, using engineering that exploits incredibly cold temperatures, very low air pressure, and hyperbolically fast speeds. Don Lincoln...

Solving the Impossible in Quantum Field Theory
The equations of quantum field theory allow us to calculate the behaviour of subatomic particles by expressing them as vibrations in quantum fields. But even the most elegant and complete formulations of quantum physics - like the Dirac...
