<blockquote>
If one wants to summarise our knowledge of physics in the briefest possible terms, there three really fundamental observations:
# Space-time is a pseudo-Riemannian manifold M, endowed with a metric tensor and governed by geometrical laws.
# Over M is a principle bundle $P_{G}$ with a non-abelian structure group G.
# Fermions are sections of $(\hat{S}_{+} \otimes V_{R}) \oplus (\hat{S}\_ \otimes V_{\bar{R}})$. $R$ and $\bar{R}$ are not isomorphic; their failure to be isomorphic explains why the light fermions are light.
# Add something about Higgs
All of this must be supplemented with the understanding that the geometrical laws obeyed by the metric tensor, the gauge fields, and the fermions are to be interpreted in quantum mechanical terms.
