One common misconception is that Engineering and Physics are perfectly correlated; that if a university is excellent in one, it must necessarily follow that is it excellent in the other. That is not the case at all, just as Economics and Business or Biology and Medicine or Political Science and International Relations are also not perfectly correlated. Below are a few examples of this:
Universities that are stellar in Physics but do not offer Engineering or are not strong in Engineering:
Harvard University (top 5 in Physics, not top 20 in Engineering)
University of Chicago (top 10 in Physics, no Engineering program whatsoever)
Yale University (top 15 in Physics, not among the top 30 in Engineering)
Universities that are slightly stronger in Physics than in Engineering:
Cornell University
Princeton University
Universities that are equally strong in both:
Massachusetts Institute of Technology
Stanford University
University of California-Berkeley
Universities that are slightly stronger in Engineering than in Physics
University of Illinois-Urbana Champaign
University of Michigan-Ann Arbor
Universities that are stellar in Engineering but not so strong in Physics:
Carnegie Mellon University (to 10 in Engineering, not among the top 30 in Physics)
Georgia Institute of Technology (top 10 in Engineering, not among the top 25 in Physics)
Purdue University-West Lafayette (top 10 in Engineering, not among the top 40 in Physics)
