2022-08-24: What Makes The Strong Force Strong?

  • 00:04: It’s strange enough for atoms, but positively bizarre when we get to the atomic nucleus.
  • 01:13: But if the strong force is so strong, why is it confined to the atomic nucleus?
  • 05:12: We need this attraction to hold quarks together in nucleons, and nucleons together in the atomic nucleus.
  • 05:19: And that attractive force needs to be stronger than the repulsive electromagnetism, while also vanishing outside the atomic nucleus.
  • 06:20: So an electron bound to an atomic nucleus will feel less force from the nucleus at larger orbitals.

2017-09-20: The Future of Space Telescopes

  • 12:33: During that collapse, the core looks more and more like a neutron star, basically a giant ball of neutrons with the density of an atomic nucleus.

2017-09-13: Neutron Stars Collide in New LIGO Signal?

  • 02:22: They are mostly composed of neutrons at the density of an atomic nucleus and are held up by a quantum mechanical force called degeneracy pressure.

2017-04-19: The Oh My God Particle

  • 00:25: ... October 15th, 1991, a single atomic nucleus travelling at 99.99999999999999999999951% of the speed of light crashed ...
  • 01:21: That single atomic nucleus carried as much kinetic energy as a good sized stone thrown at your head at 50 miles an hour.
