Title: Translations

Translations
  • We do not question how the cinematographer and
    the cosmologistdecide on a common Language, what
    they learn as a consequence, or how their novel
    collaborations relax hidden assumptions that may
    limit their work.
  • ---David Edwards,
    ArtScience

The Energy of Nothing
According to Feynman (and others)
Virtual particle-antiparticle pair, created out
of the vacuum, carries energy
  • Should be infinite

6
The Energy of Nothing
  • Large compared to everything else in the
    universe, but finite

7
The Energy of Nothing
  • Causing the expansion of the universe to speed up
    (for the last 5 billion years)
  • Before 1998, we had assumed gravity was slowing
    down the expansion

Truth and Beauty
Physicists consciously implement Aesthetic
constraints in constructing theories Beauty
as necessary prerequisite for and indicator of
truth (cf. Einstein, string theory)
  • Symmetry
  • Simplicity
  • Naturalness

10
Symmetries in Nature
Invariance under a transformation
  • Spatial symmetries rotation, translation,
    cf. mirror world
  • Time-translation and reversal
  • internal symmetries unified theories

Women have more orgasms with men who are more
symmetrical.
--LiveScience.com Is our
preference for symmetry
biologically selected?
11
Broken or hidden symmetry
  • Some interactions slightly violate time-reversal
    symmetry
  • Can explain why there is more matter than
    anti-matter in the universe
  • Which is why there is something (including us)
    rather than nothing
  • Symmetry-breaking as a transition

A basis for a film/dance choreography?
