Though the original Graph aptly describes our physical knowledge, there are some minor alterations and additions to be made for it to accurately capture the current state of fundamental physics.
* In (ii), β€œvector bundle X” should be changed to principal G-bundle.
Β 
[[Eric Weinstein|Eric]] has suggested several alterations, listed below:
* In (ii), β€œvector bundle <math>X</math>” should be changed to principal G-bundle.
* Also in (ii), β€œnonabelian gauge group G” should be changed to nonabelian structure group G.
* Also in (ii), β€œnonabelian gauge group G” should be changed to nonabelian structure group G.
* In (iii), <math>R</math> and <math>\tilde{R}</math> should be (complex) linear representations of G and so they are not equivalent.
* In (iii), <math>\ R</math> and <math>\tilde R</math> should be (complex) linear representations of G and so they are not equivalent.
* He mentioned that some info was not required, and that the Higgs is remarkably absent.

This is a modified version of the paragraph:
The Graph is a paragraph from Edward Witten's paper [https://cds.cern.ch/record/181783/files/cer-000093203.pdf Physics and Geometry], at the bottom of page 20:

If one wants to summarize our knowledge of physics in the briefest possible terms, there are three really fundamental observations:
Β 
(i) Spacetime is a pseudo-Riemannian manifold <math>M</math>, endowed with a metric tensor and governed by geometrical laws.
Β 
(ii) Over <math>M</math> is a vector bundle <math>X</math> with a non-abelian gauge group <math>G</math>.
Β 
(iii) Fermions are sections of <math>(\hat{S}_{+} \otimes V_{R}) \oplus (\hat{S}_{-} \otimes V_{\tilde{R}})</math>. <math>R</math> and <math>\tilde{R}</math> are not isomorphic; their failure to be isomorphic explains why the light fermions are light and presumably has its origins in representation difference <math>\Delta</math> in some underlying theory.
Β 
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.

If one wants to summarize our knowledge of physics in the briefest possible terms, there are four really fundamental observations:
Β 
1. Space-time is a pseudo-Riemannian manifold <math>M</math>, endowed with a metric tensor and governed by geometrical laws
Β 
2. Over <math>M</math> is a principal G-bundle <math>P_{G}</math> with a nonabelian structure group <math>G</math>.
Β 
3. Fermions are sections of <math>(\hat{S}_+ \otimes V_R) \oplus (\hat{S}_- \otimes V_{\tilde{R}})</math>. <math>R</math> and <math>\tilde{R}</math> are complex linear representations of <math>G</math> and thus are not isomorphic. Their failure to be isomorphic explains why the light fermions are light.
Β 
4. Yukawa couplings between the fermion field and the Higgs field endow fermions with the property of mass. Massive bosons also acquire their mass through this Higgs mechanism.
Β 
All of this must be supplemented with the understanding that the above geometrical laws obeyed by the metric tensor, the gauge fields, and the fermions are to be interpreted in quantum mechanical terms.
