    Electronic engineering student needs help

    Actually i have searched for some information on web(at least for accelerator physics in NIU).Maybe NIU is the only school i could get in with my profile.Anyway,thanks for your comment.:smile:

    Electronic engineering student needs help

    That means it is weird for a electronic engineer to participate in graduate research in experimental particle physics /accelerator physics?? Would my minor in physics and my research skill in EE helps ??

    Electronic engineering student needs help

    How about my knowledge in electronic?? Would it helps me to study accelerator physics?

    Electronic engineering student needs help

    I know some engineer in cern are doing accelerator physics. What knowledge do they have in electronic? I should apply to a MS in accelerator physics (e.g NIU)??

    Electronic engineering student needs help

    Being an electronic engineering,i want to pursue graduate study in physics after my graduation in electronic engineering.I'm interested in experimental particle physics/accelerator physics,but there is a thing,we have to choose a option to specialize in final year(e.g optoelectronic/signal and...

    What is more important for theoretical physics: Complex analysis or EM II?

    I think you shouldn't drop anyone math course(i.e complex analysis and differential geometry).A good foundation in undergraduate maths is crucial for being a researcher.And also you might not know which field you specialize in future.You will find EM II is nothing after you have mastered those...

    Calculating the potential energy of a spring

    That k is not force compressed,it is a quantity called spring constant or force constant.i think you really don't understand what Hooke law means.Here is the meaning,Hooke's Law states that the tension of the spring is proportional to is extension or compression from its natural length.That k is...

    Calculating the potential energy of a spring

    I think F=kx (Hooke's Law) is a great way to distinguish these 2 variables,I don't know whether it works on you,but that's my way^^(P.S It is always easier to distinguish similar variable by understanding the underlying principle of the equations) Hope this helps

    Calculating the potential energy of a spring

    Actually,the k in your equation is not the force applied on the spring,it is a spring constant(force/compressed length).If you insist on using force(18N) to calculate,you can rewrite your equation to 0.5Fx^2 by Hooke's Law(F=kx).Then you should get your answer

    Math Books for First-Year Undergrads: Proof-Based Learning

    If you are looking for some proof-based linear algebra text.i think "linear algebra:An introduction to abstract mathematics" may be an option to you.It explains everything you found in "ordinary" Linear Algebra text. What "ordinary"means?It means those just taught you computation techique,but...

    Projectile motion of a cannonball problem

    Energy consideration maybe another(also faster i think=)) method to get the answer. Try to think about the whole system energy(involve both KE and PE).Using the motion equation(Your Method), you could also get your answer eventually. Think about the VERTICAL motion(Vo sin 30), you will also get...
