    Looking for a good workbook or website

    Hello f(r)iends! I'm a first year undergraduate physics major, in my first electricity and magnetism class, and I feel like I need more practice than what is assigned in the online homework. If you could recommend a good workbook with lots of exercises and if possible solutions (not just...

    Pick my class for me!

    I suppose it's programming for me! If I can somehow make time for it I'll try to fit the Chemistry and Astronomy courses in, but the programming class will take priority. Thanks!

    Pick my class for me!

    While I'm not so indecisive as to completely let others pick my class for me, I would like your 2 cents on the matter of what I should take. So I have to take one lab science outside of my major (physics), and I have narrowed it down to three: programming for scientists/engineers, chemistry (the...

    Electricity and Magnetism Book

    Thank you for your reply, Bob S. However, I think you may have misunderstood my question. It is not the case that I am having trouble with the units for quantities. Indeed, both of the textbooks I cited use the MKS system (though I don't have trouble with CGS, either). I have to take the lab...

    Electricity and Magnetism Book

    I'm a first year undergraduate taking my first electricity and magnetism class, and going through all the classic material: Coulomb's law, electric fields, flux, capacitors, etc. And the book I have explains the material relatively well, but I feel like I'm missing out on so much by just being...

    Integral trouble

    Homework Statement \inte^{2x}cos(x)dx Homework Equations The Attempt at a Solution This isn't exactly a homework question, but it's close enough: it's from my old Calculus book (Larson), and I've been stuck on it for awhile. I just need a little hint or something. I've tried a...

    The Limit of Moore's Law

    While there are various estimates to the year in which we will not be able to continue adding transistors to a given area on a silicon chip, the typical guess is between 2013 and 2018 [1]. Given that there will eventually be a limit to how small we can make the transistor (due to quantum...

    Spheres on the GRE

    "Two small spheres of putty, A and B, of mass M and 3M, respectively, hang from the ceiling on strings of equal length l. Sphere A is drawn aside so that it is raised to a height h0 and then released. Sphere A collides with sphere B; they stick together and swing to a maximum height h equal to "...

    Related rates problem (involving a cone)

    Homework Statement Gravel is being dumped from a conveyor belt at a rate of 30 cubic feet per minute. It forms a pile in the shape of a right circular cone whose base diameter and height are always the same. The height of the pile is increasing at a rate of ____ feet per minute when the pile is...

    How to become an atheist?

    When I became an atheist I was fairly scared of telling my parents. We didn't go to church often, but the beliefs my parents held were very strong, and I knew when I told them it wouldn't go over very well. It didn't. There was a bit of screaming, some teeth gnashing, some silent treatment, etc...
