Neat! I wonder how he picked which diagrams to use. Found this: "Of particular note is the diagram on the rear of the van ... this diagram shows two muon neutrinos exchanging a particle that Feynman could only conjecture at the time. Years later, such a particle was proven to exist and called a...
Here's an example (and please feel free to point out if I've got this wrong).
When we step out into a beautiful sunny day, we can thank the weak interaction, which makes possible the fusion taking place in our star. A critical part of that process is electron capture, as laid out in this...
Working on an art project using Feynman diagrams ... I'm curious if there are any that you consider to be particularly relevant to everyday human experience or particularly beautiful (according to any criteria you wish). Thanks!
If there is no spacetime curvature in B1 and B2, wouldn't that mean there is no gravity? And if there's no gravity, how can an object in B1 and B2 still fall downward, as per Lewis Carroll Epstein's diagram of a falling object?
Question about this: Would B2 be equivalent to Newton? What exactly does the extra curvature in C (trumpet shape instead of coffee cup) signify? Thanks!
Thanks! I own a copy of Lewis Carroll Epstein's book -- so great!
The rolling up of the curved piece of paper (and its subsequent effect on the line of the falling object) makes a lot of sense. How does this compare to the more trumpet-shaped diagram? Is that one more accurate? In pictures...
Much better than the trampoline! One frustration I have with visualizations like this, though, is that they leave out time. Which seems to leave out the equivalence principle.
I am collecting ways to visualize the curvature of spacetime -- and movement of objects affected by gravity -- as per Einstein's GR. Alternatives to the bowling ball / trampoline image so often used in the popular press. Images that show the similarities / differences between Newton & Einstein...
