I will be starting PhD studies in the fall, but first I must decide which school I will attend. I am basing this on what field I want to go into. The choices are Condensed Matter/Quantum Information science or High-Energy Particle physics. I am having a little bit of difficulty deciding. I am very interested in both. I feel like CM/QI is the better choice, because there is more room for making real progress compared to HEP, where the nature of the field makes for slow progress. I definitely find the field to be very interesting. On the other hand, HEP is a little more amazing in certain ways. Although perhaps I shouldn't, I see CM/QI as a little "lesser" than the foundational work going on in HEP. I mean, particle physics seems like the elite field to be in. On the other hand, I think I stand more of a chance for happiness and success in CM/QI because of its higher relative accessibility. Any thoughts would be greatly appreciated!
