READ THIS ARTICLE!
Now, was that clear enough? :)
This is the text of the speech given by Steven Weinberg at the recent celebration marking the 50th anniversary of the BCS Theory of superconductivity. Yup! You read it right. A reductionist, elementary particle physicists speaking at a condensed matter, anti-reductionism event! :)
In it, he mentioned everything that I had mentioned earlier regarding emergent behavior and the fundamental importance of condensed matter physics that transcends into other areas of physics, especially high energy/elementary particles.
Just go read that article, why don't you? :)
