I'm not so sure that this is true.  Ask a random person on the street
to tell you anything about modern biology - something you couldn't find
in a textbook written in 1950.  How about chemistry?  I think you would
find many more people who could tell you lots of qualitative stuff 
about physics in the last 40 years than either of these other hard
sciences.  The Big Bang and the CMBR, quarks, high Tc superconductivity,
supernova observations, chaos, etc. are all, I think, widely known parts of
modern physics.

It's difficult even for physicists to deal competently with much of 
modern physics.  The reason, I think, is that it has not been synthesized
into enough clear well-established results.  Theory is far ahead of
experiment in most of particle physics and cosmology.  That means that
there is a forest of competing ideas and models, without enough data
to send most of them to the grave that they will ultimately deserve.
Meanwhile, we are faced with trying to understand many ideas which 
may fade away completely never to be seen again.  (Can you say "technipions"?)

Also, the ideas which are currently being discussed by working physicists
are not necessarily mature and well-formed.  They are often tenuous, 
hinted at by conflicting but suggestive data, and, to make matters worse, 
probably wrong.

I think that most physicists shy away from trying to communicate this complex
web of incomplete ideas and inconsistent data.  It is much easier to 
talk about 1960's physics.  There is also a mathematical barrier that can
be difficult to overcome.  Much of what motivates new ideas in high energy
physics are mathematical considerations, or at least highly mathematical
physical considerations.

Personally, I think that the market is flooded with well-written books
for the layman on interesting physics subjects.  But this is clearly not
enough to educate the general public.  I think that we need more outreach - 
community lectures and demonstrations, inviting the public into our
labs to see what we do, going into the public schools to help teachers
expose their students to what goes on out on the cutting edge, etc.
