Why aren't people posting their answers to brain teasers in hidden text? It's spoiling the answers to the brain teasers for me. :frown:

I am not sure if this is actually the correct forum but I have asked mathematics text questions before so I figured I could pose a physics text question here. If not please move my post. I picked up my text for Physics 195A, Mechanics entitled Fundamentals of Physics, Volume 1 - 7th Edition by...

"The pages of a medieval prayer text also contain words of ancient Greek engineer Archimedes. It takes high-tech imaging to read between the lines. The sheepskin parchment originally contained a 10th century Greek text, which was erased by a 13th century scribe who replaced it with prayers...

I play this game pretty much every day: It's called Unification Wars. It takes place in the future, where hyperspace has been discovered. You fight other empires for planets, which produce goods per turn, and from that you make money. The good thing is that you never loose money though. Here...

How is it possible that maths textbooks by reputable authors in their 2nd, 3rd, or even later publication can still be littered with errors in the answers...Isn't there supposed to be some form of proofing mechanism such that the *overwhelming* majority of errors get weeded out? :confused: (I...

My girlfriend has been receiving crazy text messages on her new phone, ever since she got it. Finally, the crazy person began calling her, realized she had the wrong number, and we think the messages are therefore stopped. However, we've been having a good time trying to decipher these insane...

I've learned the basic methods of ODEs but I'm looking for a more advanced book, covering things like limit cycles, existence and uniqeness thoerems, phase portraits, and so on. Does anyone know of a good book for such topics.

I want a type of effect in my text so that the text seems to be coming out of the background. So that the text seems embedded into the background but still having depth and protruding out? Unfortunately I don't have an image to show, I have only seen it a few times. I hope you understand what I...

Hi, the problem I have is one dealing with static friction. The problem states: The coefficient of static friction between hard rubber and normal street pavement is about 0.8. On how steep a hill (maximum angle) can you leave a parked car? I know that the downward force is "g" and that...

I tried to read Classical Electrodynamics - 3rd Ed by J.D. Jackson cover to cover with the aim of working through all the homework problems. Problem: The math is too prohibitive. I need to drop that book for now and pick up a book on mathematical physics and go through that first. I'd like some...

I am half way done with Physics 2. I don't feel that I learned enough and I want to review and relearn physics 1 and 2 during the summer. What is the best physics textbook, which is the most popular for freshman physics. Also, and most importantly, which is the best for self-learners? Thanks

I'm trying to save an Excel spreadsheet as a (tab-delimited) text file for input into another database. For some reason, fields containing a comma are being displayed in the text file within quotes, which I don't want. For example: John Doe appears as: John Doe Doe, John appears as: "Doe...

I (or more accurately, my beau) want to start up a chat room. - I am open about whether it is voice or text-only. In fact, I am open about whether it uses computers at all. (If someone could tell me how I could get a conference phone call going at a reasonable rate.) - it's for a select...

What is a good textbook on real analysis that has either a solution manual or solutions in the back. I have Rudin's Principles of Matematical Analysis but it has no solutions. The class I am in now is using A book called Elementary analysis the theory of calculus by Ken Ross, but it is a joke...

Any recommendations?, I'm also hoping for a book that i can find online...

In my book QM book, Gasiorowicz says that \int_{-\infty}^{\infty} e^{i(p-p')x/\hbar}dx = 2\pi \hbar \delta(p-p') Where does that come from? I mean, set i(p-p')/h = K. Then the solution is \frac{\hbar e^{i(p-p')x/\hbar}}{i(p-p')} and evaluate at infinity, it doesn't exists as the...

MS Word and keeping pasted text to original default format... Is there a way I can just highlight text to turn into the original default font or is there a way I can stop MS Word from allowing the format of different texts to be applied to the original default?

I'm taking a class in abstract algebra this Fall. There isn't a text required, but they recommend Dummit and Foot for the prelim exam. Does anyone know if there's a significant difference in the 2nd and 3rd editions? Other than about $50. There are pdf files with errata for both...

What is a damping. Text books say damping is proportional to velocity. Why not damping is proportional force? or why not damping proportional to some other parameter. What does damping actually do ? Is there any practical application ?

I'm taking an infinite series/sequence course and the text they give us is out of a textbook written by R.C Reilly. The problem is, there is no answers in the back of the booklet for me to check my answers. I've tried googling for the name of the textbook but no such luck. I understand that...

I use Opera. Sometimes, when looking at the "New posts" page, I get a little text popup (in the same style as the ALT text for images) that contains the first sentence or two of the posts. But, I can't figure out what I'm supposed to roll over to get the text. From where does it come?

Over this semester I studied quite a few physiology and anatomy books ranging from the classics of Gray's anatomy, Last's anat, Guyton & Hall's medical physiology and also Lange's histology and Lange's physiology. A word of advice to any premed student buying or reading from these books...

I'm a physics major (undergrad) who wants to learn real and complex analysis, but don't have the time to do the courses in my programme. Can anyone recommend a good textbook for learning the subjects on your own?

Anyone know any decent classical mechanics and/or thermo/statistical mechanics books that have many problems along with solutions? I hate that the books I do have, which have no solutions particlely (just talking about the stat of solutions and not the hateing of text here). It's not...

Hello all. Seems to be an excellent forum with many experts. I'm interested in quantum field theory. There's a question in my textbook (introduction to QM and QFT) and I'm not sure if I found the right solution and its interpretation. Question 1: How many energy is needed to create a...

I hope a few of you are avid perl programmers. There seems to be a surprising paucity of decent perl-centric boards out there, so I thought I'd try this one since so many smart people come here :-) I myself am new to perl but have plenty of experience in C++/Objective-C and other languages...

Hi, I am not seeking a "complete" treatment of distribution functions (like Gelfand or Schwartz). However, I would like some discussion in regards to multiplying delta functions together---especially in QM. From the little I have discovered, distributions do not form an algebra, and thus...
