    The heisenburg uncertainty principle

    The uncertainty principle is fundamental. You can even derive the result by using the commutator relation: [x,p]=ih*2pi

    What is the correct way to measure an electron's spin in a magnetic field?

    So I've gotten myself stumped the other day. Suppose I have an electron in a magnetic field, where the field is oriented along the x-axis, than I know that the H-matrix/operator is defined as -g*|B|*h/2 *Sx. Now say I know that I have a wave-function in a known initial state-vector, let's...

    Solvated ion in water solution with surface effects

    (Note: I am posting this in the classical physics section because it has a connection with Thermodynamics, also this is NOT a homework question, I am just trying to get a handle on what is going on) I was looking through some old questions I had written down and decided I would ask to see if...

    Prof teaches Statistical thermodynamics in a Classical Thermodynamics class

    If you feel like you are really missing out on the classical thermodynamics, there are plenty of good texts to cover this material. However, it has been my experience that the most useful texts to cover classical thermodynamics has been Physical Chemistry texts. McQuarrie is a good text for this...

    Method of Images Question (Concave Geometries)

    Well a semi-reasonable approximation to the catenary shape is that of a hyperbola (at least at distances close enough to the hyperbola, and since my problem is with something close enough to the catenary anyway, I am not too concerned with making this substitution). I don't have much...

    Method of Images Question (Concave Geometries)

    I've been working with image charges for a while now, and I have noticed that I haven't been able to find a single discussion on the use of image charges for concave geometries (i.e. a charge on the "inside" of a catenary shaped curved conducting plate, see attached picture). Has anyone worked...

    Biology for Physicists: Books to Learn From

    Molecular Biology of the Cell...I dread this book. It is quite informative, but if you are use to reading physics texts that are often provoking of questions, or at least have derivations or reasons presented outright to work though, you may find this text painful. The text was written for...

    The Greats in Math: Texts to Read & Pre-requisites

    Spivak's Differential Geometry series. Not the little softcover, but the huge anthology (A comperhensive introduction to differential geometry) is very useful if you want to get a handle on Diff. Geo.

    What Should I Actually Use Next Semester?

    I am not a big fan of Schroeder's text for thermo. Something about the style of writing gets under my skin. Seeing diagrams that include wizards in a physics text just doesn't sit well. If you want something kind of dry for Thermo, I'd pick up pretty much anything by McQuarrie, though it is...

    Recommended Physical Chemistry Text

    McQuarrie's new textbook on Physical Chemistry is a great text. And if you take stat. mech. later with McQuarrie's legendary Statistical Mechanics textbook, you will have quite the advantage.

    Book on diff. geometry, tensors, wedge product forms etc.

    Quick answer: Lovelock Long Answer: The author,, Lovelock, published a text years ago entitled something along the lines of "tensors, differential forms, and variational principles." Its in print currently by Dover. Short, sweet, and to the point for most of differential geometry. If...

    Courses A question about being an Undergraduate taking Graduate coursework

    I know it may sound strange, but I by time I finish my undergraduate degree in physics at my current university, I will have taken the graduate Stat. Mech sequence, Quantum Sequence, and Classical Mechanics Sequence. And, no I don't mean the senior level/graduate split course work, I have also...

    Engineering Most useful (spoken) language to learn for a Nuclear Engineer?

    Chinese! China's economy is growing rapidly as well as it's energy need and from what I have heard reactor interest is sparking. Additionally, if you can master Chinese, many other East Asian languages are pretty easy to pick up. 8 weeks of Chinese (in an intensive course of 4hrs a day 4...

    How can I use Markov Chains to predict a user's next choice of color?

    Since you are trying to use previous data, have you considered a Neural Net learning algorithm. My computational physics professor found one in a standard introductory computational physics book that may work for you.

    Which Calculus Book Gives Best Understanding: Spivak or Apostol?

    Spivak is a great choice for a calculus text, especially if you plan on eventually studying Differential Geometry, since it gets you use to his style of writing.
