I posted a reply to your question on your thread on the other page, but here is a list of the Physics and Astronomy Department at URoc. Take a look at what these profs have as interests - and their websites if they look intriguing - and then compare to the dept at Amherst. Make your decision based upon where your interests lie - which school matches better? Students I’ve had have really enjoyed researching things they like and are rather blase about having to pick from school options when their interests don’t correlate.
