I'm looking for a document or a picture that represents the most
important 20th century physics theories with their interdependencies.
E.g. quantum electrodynamics would have two dependencies -
nonrelativistic quantum mechanics and SR; loop quantum gravity
probably depends on GR, which in turn builds up on SR, etc. Having
dependencies on new math theories would be great, too. I can't seem to
find one in the Internet. Can anyone point me in the right direction.

Thanks

Along those lines but from the math side,

Think of the nodes in your dependcy graph as the pages, and the links
as the arcs. You could generate an actual graph after creating the
pages (MS FrontPage & Visio have some visualisation tools that MIGHT
do the job).

I guess every page on the internet to do with modern physics is part
of the dependency graph you are looking for!

How do you define 'most important'? Roger Penrose would differ greatly
with Brian Greene on deciding whether string theory or loop quantum
gravity is more important. I bet people would differ greatly on
interdependencies as well! Why not take Roger Penrose's book:

http://www.321books.co.uk/reviews/the-road-to-reality-by-roger-penrose.htm

.... and work out a dependency graph for the theories he discusses.
He's very good at cross-referencing and has many short sections so it
would lend itself to this approach.

After that do the same with mega-books fronm other big names. It would
be interesting to see the different dependency graphs. See you in ten
years :-)

Have a look at http://hyperphysics.phy-astr.gsu.edu/hbase/hph.html
I think this comes close to what you are describing.
