After yesterday’s discussion of how a magnet works:

Richard Feynman Magnets

I happened to read a piece by Frank Wilczek on how mass works, which I thought tied in quite nicely:

Masses and Molasses

(Starts on page 216)

The Wilczeck piece first appeared in New Scientist in 1999.

If you click on “next” just above the text it takes you straight to page 217.

I had a thought yesterday – Feynman was the trouble shooter they might have called in or threw a question at on the fly to see what he might come up with to move the process along

“Take it as a given. I can’t explain that in anything else you are more familiar with”. That’s supposed to be an explanation?

No page 216. Do you mean starts page 219? Ah yes, you do. OK, I recognise the explanation of particle mass as due to the viscosity of a Higgs particle condensate “molasses”. Pity there’s no explanation of why a condensate of Higgs particles is stickier than a condensate of Nambu-Goldstone bosons.

It’s because they are sexier…

That’s odd.

The article definitely starts on Page 216 for me.

Page 219 has a box entitled Higgs particle cookbook.

I think it is a reasonable statement of what can and cannot be explained in the given context (interview by a non-scientist with limited time, and presumably lots of other stuff to talk about).
