- 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,

5The Energy of Nothing
According to Feynman (and others)
Virtual particle-antiparticle pair, created out
of the vacuum, carries energy
6The Energy of Nothing
- Large compared to everything else in the
universe, but finite
7The 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

9Truth 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
10Symmetries 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?
11Broken 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?
