@phyzguy oh yeah! I'll get a classic, dutch, city bike. Love that style

Thank you all guys! I just wanted to let you know that I finally made a decision, and I'm choosing UC Davis!

Thank you so much! I'm starting leading towards davis especially for the Campus and the weather, I'm not sure how I'd like a city campus... Also, since you went to Davis, what do you think is the education there? I'm really looking for a Uni that can challenge me and prepare me for Graduate...

Thabk you so much! I know that they don't mean so much.. But after all, is the only source I can check at the moment ☹️ Do you have any personal experience about the two? If You were me, and both school were exactly the same for campus and weather, what would you choose? Thanka again!

Thanks! Yes, i can afford both, but however i don't have the opportunity to visit. It's a really tough decision, in every ranking I go, they are always very close. BU US News Global School --> 32 Davis US News Globa School --> 39 BU US news Physics --> 39 Davis US news Physics --> 29

Hi everyone! I'm an international student who just got accepted to those two great Unis! I'm really happy, however, I really don't know where to go. I plan to major in Physics, and to continue my grad school in physics too, especially, theoretical physics. Could someone give me an objective...

Einj is right :) I would also add that for principles of quantum mechanics, the eigenvalue of an operator is precisely the measure of that observable, then definitely after the measure will have an eigenvalue of the operator even if the state is not one of its eigenvector.

Thanks! :)

Thank you for your reply. But in theory... a_p it should not destroy the particle created by a^+_p?? What am I doing wrong? :confused: Thank you.

Hi everyone! Im' a new member and I'm studying Quantum Field Theory. I read this: "The interpretation of the real scalar field is that it creates a particle (boson) with momentum p at the point x." and : \phi\left(x\right) \left|0\right\rangle = \int \frac{d^3p}{(2\pi)^3(2\varpi_p)}...
