In awe of spaghetti

If I try to tell what pulls me most to the spaghetti model, here is my candidate:
Gauge groups follow from shape deformations.
I find this so strange and bewildering.  It is unexpected. I have so many positive feelings attached to this.

Maybe because I read it just before my surgery. Life saved, but no child. I used to get impatient with people who care more about their ideas than about their children. I still do. But now I am left myself with the ideas only. Fate.

Spaghetti shape deformations as gauge groups. The connection makes me dream. The dreams are coming back, slowly, and they are beautiful. Again.


  1. Thanks, Clara.

    I'll have a read of chapter 9, 'Gauge Interactions Deduced from Strands', and see if I can follow it.

    I don't really understand this gauge business, though. If you change the point on the gauge that you mark as phase-zero compared to where you marked it somewhere else in space, the laws still work, only now it looks as if there is an electromagnetic field. But if there was an electromagnetic field, wouldn't there be forces too? For the electromagnetic field you get by changing the point on the phase-measuring gauge that you call zero degrees of phase, do the forces from the electric field part and the magnetic field part always cancel out, or something? I don't understand. (This has nothing to do with the Strand Model.)

    Sorry to hear of your misfortune.

    1. Are you mixing up fields and vector potentials?

    2. Thank you, Clara.

      That was the clue I needed. So you describe the electromagnetism with a big field full of vectors, but you can use different fields of vectors, and they still give the same electromagnetism. Each different field full of vectors that is the same electromagnetism just corresponds to a different choice of whereabouts you decided to mark the zero on your phase-measuring dial gauge.

      I wonder why that is then. Well, the Strand Model says it is because electromagnetism is basically just the phenomena associated with the simplest way to add a new tangle to a strand -- by twisting it.

      Next most complicated is you can tangle two strands by poking one across another -- and that is why you get fields of vectors that all give the same physical thing: a weak nuclear force field (but with different positions of zero marked on two dial guages, this time).

      And the most complicated is you can tangle three strands by sliding one strand past where the other two cross -- and that is why you get fields of vectors that all give the same physical thing: a strong nuclear force field (but with different positions of zero marked on three dial gauges, this time).

      You are right, Clara! That is neat!!!

  2. Sorry to hear about the loss of your baby. If it is a health problem, you can adopt one.

  3. Clara,

    I am so sorry to hear about your heartbreaking loss. Stay strong, continue to believe in the wonders of life and never give up!

    With best regards,
