An Introduction to pH and Buffer Solutions Calculations [work in progress] This is a work in progress 1. pH and Strong Acids pH is defined as the negative logarithm of the hydrogen ion concentration in a solution; pH = - log10[H+(aq)]. (From this point forward 'log' will represent log to the...

Nice lectures describing the theory of Quantum Computation. I'm currently watching them. http://www.quiprocone.org/Protected/DD_lectures.htm

Does anyone know how many chapters Courant & John's "Introduction to Calculus and Analysis, Volume II" has? Because I've found a 4 chapter reprint, and was wondering if I should get it.

I'm searching for some online text concerning an introduction and somewhat more advanced topics in ring theory. ps:if you come across on notes for Model theory it would be great too,thx.

Wikipedia - http://en.wikipedia.org/wiki/Plasma_Physics And other references - A nice introduction, including history, to Plasma Physics http://farside.ph.utexas.edu/teaching/plasma/lectures/lectures.html and more sites on Plamsa Physics, which include applications in...

Hi! My name is Annie and I am a freshman at UW-Whitewater. I am currently in the introduction to astronomy class. In high school, I took physics and loved it. I even got the 2nd highest grade in the class! This is even more telling when you know that it was a predominantly senior class and...

I have a homework question asking to construct an orthonormal system from the three functions: 1, x, 3x^2 - 1, I know we can approach it using linear algebra method, but as this is a calculus course, I don't think that's what my prof wants us to use. Can anyone guide me through this? Thanks a bunch!

So, where do I begin? I have a current interests in going into Algebraic Topology and I am currently learning about Point-Set Topology and Abstract Algebra, which are pre-requisites to Algebraic Topology. After talking to a professor, he recommended learning some Differential Geometry, but...

Hi string group, I'm a new member. In a few months I'll have completed my final exams and can finally start to write my diploma thesis (german diploma) in theoretical physics and mathematics. Naturally I'm a novice in the subject, having only very superficial basic knowledge from a...

I'm going to study genetics in college next year, and I was hoping I could get a head start. I have looked at many books such as the Cartoon Guide to Genetics, Schaum's Outline Of Genetics, Genetics for Dummies, etc. But I was afriad of some of these books being either too advanced or too...

Hello I am looking for a good book that will give me an introduction to chemistry. I work in the optical field (glasses, contacts etc.) and work with plastic monomers and polymers and would like to know a little more about them and why the react to certain conditions the way that they do. Any...

Hey there fellas, I just joined this board yesterday. I'm a "Vet" over at Bodybuilding.com, so I'm aware of how boards work, just so you understand I'm not just joining the site and making a new thread. I've gone through all of the archives and read through the threads that seem to be about...

Hey guys, I haven't taken thermodynamics yet, I have only taken it in general chemistry, which amounts to pretty much nothing. But I've heard from many friends that Fluid mechanics is a very tough course, so I am trying to teach it to myself before I have to take it next year. I've only...

First let me say, I have absolutely no idea how to do these. If anyone could show me how I would greatly appreciate it. (Thursday 8/25/05 was my first day in this class) Q1) A crane must lift a crate with the mass of 3.5x10^3kg a. How much force would be required? b. On the...

I'm stuck on this problem in the "Relativistic Particle Mechanics" section, number 26. I had no trouble with the first part... but the second part I'm stuck. "Two identical particles move with velocities +-u along the parallel lines z=0, y=+-a in a frame S, passing x=0 simultaneously. Prove...

What is chaos? Hello everybody. I just wanted to know if anyone could explain to me what is chaos all about in verrrrry simple terms, because I found a book on it in the library and I wanted to know if anyone could please give me a simple introduction to what it is as I find the book quite...

Does anyone know a good website, or have a PDF file that gives a good introduction to congruencies? I can't seem to find one on the internet. Thanks for your help.

Help on "Introduction to Electrodynamics 3rd edition by David J. Griffiths" I'm studying that book right now, but I'm having a hard time understanding... Can someone explain what a dirac delta function is and how to use it? I also don't understand the what is the electrostatic boundary...

Please suggests books which could thoroughly introduce me to the field of cosmology/astronomy (i hardly know the difference between the two). I require a full guide -- a 'scientific Bible', if you will.

Is this book worth it? It seems like an interesting read.

Which book would you recommend for introduction to aerodynamics? One which is mathematically rigorous as well as comprehensive?

Alright, I did the whole Hello World! thing, but I got stuck on one part. I downloaded the Sun.Java thing, but now when I go into the command prompt and to try and compile it... the computer does not recognize the "javac" command. What's going on? Is there another program?

Hi everyone, I am going to take a digital electronics course next sesmester. But, I know nothing about Digital Electronics. What books do you recommand for introduction to Digital Electronics? And, any website for this course? Thanks.

Hi, Anyone out there have Lawden's book, "An Introduction to Tensor Calculus, Relativity and Cosmology"? Expression 39.13 (on p 109) and the sentence that precedes it have me stumped. My understanding of what he's saying is that a symmetric quadratic form can always be diagonalized so that...

Hi all, I wanted to study Lie groups and their connections with differential geometry. But i don't want to get involved with lots of 'deep physics'. I am familiar with a little bit of group theory. can somebody suggest the right introductory material like tutorial papers or books for such a...

Greetings--I have a few questions from An Introduction to Quantum Field Theory by Peskin and Schroeder. Note: I'm not sure how to construct the contraction symbol using \LaTeX, so instead I will use the following cumbersome convention: \overbrace{\psi(x)\overline{\psi(y)}}=S_F(x-y), they...

I really don't want to define a homomorphism like psi(p(x))=p(x-1+I I'm looking for another way to solve that next question: Show that Q[x]/(x-1) is isomorphic to Q[x]/(x-2). Any ideas? Thanks in advance.
