3 Comments on "Richard Feynman and The Connection Machine"


  1. i’m always interested in accounts about richard feynman but i’m confused by the reference to quantum chromodynamics (which i had always understood to involve assigning colours such as red, green, blue, anti-red, anti-green, and anti-blue to quarks in order to keep them from violating the pauli exclusion principle) rather than quantum electrodynamics (which feynman wrote a book about called “QED: The strange theory of light and matter”)…


  2. Assigning colours to quarks is about the strong force – this is the one they mean in the article since it mentions internals of particles such as protons.
    Light and matter is about the electroweak force.


  3. ah, thanks for that – that one statement explains a lot more about qcd (or perhaps what falls under that heading) than i was ever able to find in my highschool library back when i was really looking into such things…
