Matlab GUI: putting several "edit text" inputs in one matrix Hi, I'm making a Matlab GUI that will ultimately send data to a robot. I have about 60 numbers being 6 polynomials of 10 terms. My "edit text"-boxes are currently named motG_RN_0 where the R can also be an S or a T and the N can also...

I was reading my textbook to study for a test in my C++ class and I cam across this question and the answer is not in the book. I'm afraid I might need to know how to do something like this for my test and there isn't an example of one like it in my book. I'm not sure how to do it so I don't...

"we want to calculate the heat enrgy of a gas molecule n - is the number of molecules per volume v_th - is the average speed of gas molecule L - is the distance which travels one molecule in a certain time we have six directions for which they travel +-x +-y +-z so in each time n/6 of...

Does anyone have any recommendations of a good book(s) for a first undergraduate-level course in Statistical Mechanics?

Hello All I have recently recovered from a 4 year hospitalization which pretty much ended my career as a computer scientist. Much of the time I was barley lucid and thus time and medication have taken their toll on my memory. Although I retain much of the theory, I have found my knowledge of...

Hello :smile: I have a homework question regarding Gaussian Elimination, where I am supposed to use information in a block of text to get equations, and form an augmented matrix. There are 4 unknowns, but I can only seem to get 3 equations and 3 "checks", to see if the values I get are...

I'm looking to get a book on introductory Electrodynamics. I've already seen recommendations for This one: https://www.amazon.com/dp/013805326X/?tag=pfamazon01-20 But it seems really expensive. Are there any other good books for ED? Also, does intro ED require linear algebra?

This is a question from a chem textbook but it seems relevant to electrodynamics/quantum mechanics. The energy to ionize a hydrogen atom in its ground state is given by: En = -Rhc / n2 Ei = Rhc (because the electron is being taken to infinity) = 1312kJ/mol The book claims that to ionize...

Hello there, I would like to just say before beginning that this is an excellent forum, and I have found it invaluable as a prospective physics student. I'm looking for an undergraduate Electricity & Magnetism text which will lead me into, and through, my Physics degree. Just a bit of...

After deriving the self energy, or the energy to construct a charge configuration\frac{\int_{V} \epsilon E^{2}dV} {2} (where V is the volume over which the E-field of the configuration extends.) Griffiths goes on to say that the energy required to construct a point charge using the above...

My mother has always insisted that I have a cell phone with text capability. She says that she's heard that sometimes when cell phone service is not available, people will still be able to send text messages. I believe she's thinking that after a natural disaster, like an earthquake, all the...

Hello, Im struggling with a pretty horrendous lecturer for this 2nd year course, so am trying to learn a lot of it myself with a decent textbook. I am getting pretty scared for the exam in summer. We have been reccomended Jewett & Serway, but its kinda just a general physics, and doesn't seem...

Hi, I'm new to Physics Forums, but I'm glad to be here. I'm in 10th grade and I'm very interested in physics. Since I was in an early grade (5th) I would scour my textbook and my library looking for anything related to physics. Unfortunately I didn't have enough math skill to understand...

Homework Statement Okay so I'm trying to teach myself the first three chapters if Grimaldi before I take a discrete math course in January. I'll probably be posting a few problems. The question is as follows: In how many ways can we select n objects from a collection of size 2n that...

I need program code that will extract part of a text string. For example, I have the following text string: '10-Nov-2009_0.91304_Network_N=100_k=6_p=0.02_COMM_NETWORK' and I want to wirte code that will result in a command N=100 (ie, assigning a variable N the value of 100). I have figured...

I'm not sure if this is the right forum, but I'd like to know: What's a good physics text that uses calculus? I mean, not just uses calculus in the definitions of velocity and acceleration and whatnot, but uses it in almost all the problems? I find my current text, "Fundamentals of Physics" by...

I'm going to take an engineering physics class which is just simply a calculus-based physics class. Any suggestions for a book? The class uses Serway's Physics for scientists and engineers, but I've heard of other authors like Resnick, Giancolo, etc. Thanks.

Hi, I'm taking a Fluid Mechanics course. The lecturer is very closely (letter to letter) following the book by Kundu and Cohen (https://www.amazon.com/dp/0123737354/?tag=pfamazon01-20). I think K&C has a bunch of isolated derivations with no examples or solved problems. The 'examples' they...
