i was reading a Murray Gell Mann interview and he mentioned that Heisenberg became a crank in his later years. I've tried very hard but I cannot find what Heisenberg was working on. My motivation is, there may be some bits of genius among that pile of crackpottery.

I came to these forums with the question how do I understand math intuitively. I joined and started this topic https://www.physicsforums.com/showthread.php?t=614527. I wanted to be able apply the methods quickly, without any calculation, so I could gain some further understanding. I read a few...

Homework Statement Weak Duality Theorem. If x ε ℝn is feasible for P and x ε ℝm is feasible for D, then cTx ≤ yTAx ≤ bTy. Thus, if P is unbounded, then D is necessarily infeasible, and if D is unbounded, then P is necessarily infeasible. Moreover, if cTx = bTy with x feasible for P and y...

Hi there, does anyone know a software or program that i can use to quickly sketch / draw and write as if i was writing in pencil ? For instance, paint is of no use, because it can't be edited. Photoshop is kind of hard to simply make straight or curvy lines without too much trouble. So...

So we're converting these currents from phasor to time domain with ω=4. I understand I1, but not how the lecturer got I2, is this an error with the notes? We have these phasors: Which are converted to this time domain (respectively): Any help is much appreciated.

I want to make my own math notes in the same style as this. Anyone know the program that is used? It is the easiest to read font I have ever read in my life! http://www.math.cornell.edu/~bterrell/dn.pdf

I'm looking to buy a tablet to take notes at school, because I write much faster than I type and I don't want the clutter of physical loose leaf paper or go through the trouble of transcribing my notes onto the computer, not to mention having to draw diagrams with my mouse which is a nightmare...

Hello everyone. I'm trying to do a homework in digital integrated electronics class and feel like I can finish it only if I had a good set of notes. I have problems like comparing the input capacitance of a Mosfet to a wire of certain length, getting RC time loss in a wire, power...

Homework Statement I'm trying to self study Green function and I can't follow the very last step of a demonstration in an online notes (that I attach in this post). Page 7 to 8. Basically he says that from G_{tt}(t,t')+\omega G(t,t')=0 for all t>t' with the conditions G(t,t'+\varepsilon)=0...

We are currently going over Kinetics in my AP Chemistry class but I am struggling with kinetics, our book is not very clear and tackles on several ideas at once making it hard to understand. My teacher is also not very helpful, sadly. I have been searching for some notes on Kinetics but have not...

So I'm starting to review Calculus and I was wondering what you guys do for taking notes from textbooks since I don't normally take notes and I would only read the text when necessary. I am debating taking the following options: Just reading the book (probably least effective) Reading and...

Hi! I'm new to college so i have a few questions. What specific things do you pay attention to when in a mathematics heavy course? Have you tried using tablets or laptops to take notes? For those of you that have used tablets do you have a recommendation for a specific tablet and programs?

One day I borrowed a book published by Springer (For learning Mechanics). I find it very difficult to follow. Later, I discover that it is in fact Lecture Notes. I am only a yr 1 physics student, but I want to explore as many area in physics as I can. My question is, are Lecture Notes such as...

Hi all , How can I find lecture notes on ArXiv ? I was looking for lecture notes on Yang-mills theories treated in the language of differential geometry but didn't succeed till now . Can some one recommend me some good resource for it?

For fun, I wrote some notes on integration which should provide a good solid introduction to the subject. They are not analysis notes but more of a first introduction to integration. Any (constructive) comments or suggestions are always welcome. Mat

How do you take notes for physics classes and what note books(Brand) do you use? Before I just to take notes on line paper and put the notes into a binder, but now I found taking notes in a notebook easier to organize(and harder to skip class). I'm trying to find some good quality notebooks...

I have made some study notes on probability. Please have a look and see if there are recommendations. I'm forced to follow the syllabus in Hong Kong so I had to add some boring and nonsense stuff inside (unfortunately).

Hello, I am currently writing a paper for submission to the PRL. I wish to put in a note after the names of the first two authors, stating "These authors have contributed equally to this work". I would like to solicit the help of the Physics Forums community in knowing how to do this. In some...

A friend of mine says they can tell which 2 notes are being played together on a piano keyboard. How can this be if the 2 notes combine to form a single wave (sum of the 2) ?

Let's see if anyone can identify the author of some 1980's lecture notes on introductory linear algebra. I bought this bound set of lecture notes in a used book store. The title stamped on the binding is "Linear Algebra . Thomas". These are images of 8 by 11 1/2 inch typewritten pages...

I have started to write Abstract Algebra notes as I am learning them, and typing them with LaTex afterwards. I have just done a bit but I want some of you to help and see if I have got any thing wrong (having the wrong concept in your mind can have terrible consequences) or anything else to make...

Hello! Is someone aware if there are lecture notes about Lie Groups from a physics course? I would to study an exposition of this subject made by a physicist. Thank you in advance!

Notes: http://www.damtp.cam.ac.uk/user/tong/qft/three.pdf On page 59, in deriving 3.48, from the first step to the second step, why can we just insert |0><0| like that?

i'm taking the first semester of intro chem (major-level) and i was wondering if anyone knows of good online notes to supplement what i learn in class? thanks so much :)

I was wondering if there is any compelling reason to read the assigned book instead of lecture notes either from the actually professor of the course you are taking or from another another source online as opposed to the book if they seem to cover the same material. Currently, I in my 3 "real...

Hi. I'm reading these notes: http://arxiv.org/PS_cache/gr-qc/pdf/9707/9707012v1.pdf and have a few questions. (i) On page 11, why is equation (2.1) true? Where does this come from? I guess the timelike feature manifests itself as the minus sign at the front but I could really just use...

I have a very simple question about the Dirac equation that I just cannot see the answer to. In these notes: http://www.damtp.cam.ac.uk/user/tong/qft/qft.pdf In equation 4.115, I keep getting u( \vec{p} ) = \begin{pmatrix} \sqrt{p \cdot \sigma} \begin{pmatrix} 1 \\ 0 \end{pmatrix} \\ \sqrt{...

I have a feeling I'll need something to supplement my Gasiorowicz textbook.

I teach an introductory maths course which includes function, algrbra, co-ordainate geometry, quadratic equations, limits, differentiationm trigonometry, exponentials, logartithms and complex numbers. Is there a way I can post these notes somewhere on this site for people to download?

as uploaded. I think the example is very weird. Why we can use conservation of momentum? There is external force! thx.

I have attached a lecture note which is meant to provide understanding on the following learning outcomes. appreciate the distinction between the macroscopic and microscopic views of matter understand the main qualitative differences between solids liquids and gases at the microscopic...

I would like to know if anyone who had a good introductory GR course would mind sending me the scanned lectures notes if this person has them. I think textbooks have too many words and I prefer to study lecture notes. I am sorry if this was not the correct place for my post.

Didn't know what section to really post this, but exam time approaches. And we all know what that means. That's right, procrastinate by doing the most mundane things just to avoid studying! Last year was adding lyrics and album art to every song on my iPod. Took about a good 8 days. This time I...

I just finished the first week of the term. It was very loaded I must say. I also ended my introductory courses and I'm now taking upper level undergraduate physics courses. My professor wrote notes for us because he doesn't really like Jackson's book, but I'm having a very hard time to...

My wife informs me that next weekend I want to see the new Sherlock Holmes movie with her. She likes murder mysteries in general and she especially likes the Sherlock Holmes series with Jeremy Brett. I don't mind seeing all those dead bodies on the TV, but I wish she wouldn't take notes while...

How do you interpret this?

Here are some notes that I've finally compiled. They are taken over the course of the last two years of study and I've neatly coded them into a pdf by way of LaTeX for your enjoyment. I haven't gotten most of the figures in yet, but all of the equations are there, and most of the text/comments...

Hey Everyone, I was wondering if anyone could post some good online resources which teach one how to use LaTeX to write up notes for a math class. Thanks.
