I wanted to do some physics over the break, electricity and magnatism to be exact. I have already taken the course so I am not going through the material for the first time, I have also take vector calculus. The book I wanted to buy was Electricity and Magnetism, Vol. II
by Berkeley Physics

I believe the original question was, is there a school that offers a mojor in quntum computing. The University of Maryland offers graduate studies for physics majors in
Quantum Electronics: Relativity & Quantum Mechanics
Spintronics & Spin Quantum Computing
Superconducting Quantum...
the question is "evaluate \iiint z \,dv, of a solid tetrahedron bounded by the four planes x=0,y=0,z=0, and x+y+z=1"
I can set up the problem correctly but i can't seem to integrate it right
\int_{0}^1 \int_{0}^{1-x} \int_{0}^{1-x-y} z dzdydx
(1/2) \int_{0}^1 \int_{0}^{1-x} (1-x-y)^2dydx...
"A solid conducting sphere with radius R carries a posative total charge Q. The sphere is surrounded by an insulating shell with inner radius R and outer radius 2R. The insulating shell has a uniform charge density \rho a) find the value of \rho so that the net charge of the entire system is...
I was a bit confused by a homwork problem that I was working on. The problem is that I found the flux of a charge and I know the demsions of the Gaussian surface it is encolsed in. It doesn't seem right intuitively to be able to find the location of the charge from this information...but...
Hello all, i am trying to write a script file that will only print if R is divisible by D where D=3
I wrote a loop statement with the condition being fix(R/D)=R/D this works fine but there is another way that the book does it. The book uses mod(R,D)=0 as the condition. I tried typing in help...
Hmm, so I guess sleep is just something I have to get over. I know some people that allmost never catch up on their sleep and do very well in school. But I read an article somewhere that said if you don't sleep 8 hrs you won't be able to think creatively.
what about the z's ??
I am a physics major in my second year and I wanted to know how other physics/engineering students manage their sleep. Basically I was wondering how other students sleep patterns are and how it works out for them.
course called "scientific and engineering computation"
I am taking a course called "scientific and engineering computation" using the MATLAB program and I was just wondering where should I post questions on this topic?
Okay what I don't understand is ...the conservation of angular momentum requres there to be no net torque...so are you saying that individually there is a torque but not on the system of the two disks?
If you had two disks with the lower one rotating and dropped the one on top onto it they both come to the same angular speed b/c of friction. How come there is no torqu action on it? Would the friction be in the plane?
Hi my problem is I have a platform that is rotating and it \omega_0=8\pi and the question is how long does it take it to stop. All my work up to here is correct and I have \sum\tau=I\alpha where my \sum\tau=3.75Nm and I=1.91kgm^2 and \alpha=1.96rad/s^2 so I wanted to use the \omega=...
