Hi everyone, so I was relooking into the external EEPROM problem I had earlier for the Arduino, and am thinking that I am missing even just a basic understanding of it. So I'm using this https://www.sparkfun.com/products/525 EEPROM which should have 256kbits of space. I am hoping to save 4...

I am shocked that there are only a few schools which got their graduate engineering program accredited by ABET. FYI, I used this website: http://main.abet.org/aps/Accreditedprogramsearch.aspx For undergraduate programs, there are quite a few schools which have ABET accreditation. For...

I will be graduating with a BA in physics and BS in Electrical Engineering in May. I want an optics PhD. I attended an info session on Sandia National Labs at my university, and the recruiters made me think about a PhD program through a national lab. If someone has experience with the National...

Hi :) I need to program several nested 'for' loops which differs only in index of their variables inside. So I need to convert this: for i1 = 1000:-d:0 for i2 = (1000-(d*i1):-d:0 ... for in = (1000-(d*in-1):-d:0 some function containing all index variables like: b=(i1*A( :,2), i2*A( :,3), ...

Recently, I have came across an interesting game that can be played fairly easily between two people. Here is how it is played: Both you and your opponent pick a four digit integer with no digit repetition. Then, you perform specific "guesses" so as to determine what their number is. A guess is...

Definitely looking to pursue graduate level theoretical physics in Quantum Mechanics. Which undergrad program would be best? Mathematical Physics, General Physics, or Astrophysics?

Hi all, I have been curious about this for a while. I know that some schools do not accept a bachelors in engineering technology for into a Master's Program of Engineering. I was wondering if anybody could tell me if there are schools that do? Thanks

Hi there A while back I updated Ubuntu to version 14.04. Before this, I could connect to the machine through TightVNC from my Windows 8.1 laptop. However after the upgrade things didn't run smoothly. It is now a known bug that usual VNC software can't connect to Ubuntu 14.04 because it uses...

I am trying to figure out why my program gives wrong results or not execute for big values. I am trying to compute how long before a bank account is depleted if it has an interest and 500 is withdrawn from it monthly. If I use 100000, it gives a value of 526years, which I think is wrong. And if...

Don't know where else in Phyiscs Forums or on the internet in general to ask this, and if it's inappropriate here, I apologize. My question is: is there an open source library or resource that I can access from a C++ program to perform symbolic computation on the level of something like Maple...

Hello, what PCB Design program do you prefer? What's the reason for your choice? I am freshman to PCB design and working on PADS from Mentor Graphics. But I have to admit it seems me a little bit unintuitive and I am unhappy with non-perfectly fitting transmission lines and prolonged editing...

The Sands of Duna <Intermission (1/2)> An intermission of math. Skip this post (and the next) if you are not interested in the math. But since you are reading this on Physics Forums after all, there's a good chance you are interested. If so, read on. :smile: Collinsmark is not affiliated...

I remember someone telling me that it's impossible to create a program that determines whether a given program runs forever, and that this requires a rigorous and long proof. Well, I was thinking about that today and the proof should be trivial -- shouldn't it? Proof. Let P be the set of all...

Hello, I am wanting to write a math/physics book or possibly a PDF online book and I'm wondering if anyone knows of any programs that exists for making pictures and drawing diagrams. I not just looking for something to make x-y graphs or 3-D graphs, I'm looking for something that designed...

Hi people, This is the first time I am writing a letter to a professor about my enrollment into their MS program. i have already completed a draft with my cgpa, current thesis, research interest etc. Now do I write the whole detail in the body of the email or i make a doc file and attach it...

I forget where I saw this I think it was the Halo series with the Cortana AI but basically a program used a human brain for processing information and running itself. Would it be possible to have a program running on a human brain? Would the principle be similer to IBMs' TrueNorth chip...

So, I started trying to learn how to code a few weeks ago. I'm trying to currently learn HTML + CSS right now through Code Academy, but I am having trouble actually understanding the material and the purpose of some of the functions. I was hoping to get this product off of Amazon...

The Sands of Duna Part 1: Introduction So let's go to Duna! (Duna is Kerbal Space Program's [KSP's] analogue of Mars.) Here are some mission requirements that I set out for myself: Mission requirements: Bring two or three Kerbals to the surface of Duna and bring back all sorts of...

Is there a widely used free drawing program that is used in conjunction with LaTeX for math books and physics text? Thanks, Chris

Homework Statement In the previous few modules you studied the problem of minimizing ##\| Ax -b \|_{2}## by choice of ##x##. So far you've done this in Matlab using either the backslash operator or the command pinv. Now that you've been exposed to linear programming, you have the tools to solve...

The reason: I live in a small waterside town and we are very concerned over our water table. The problem is that we don't have a lot,if any, research or organized data to back up important decisions. The problem is that no one is informed on what they're talking about, many regulations...

Homework Statement Suppose you are given the following affine minimization problem. \begin{align*} \underset{x \in \mathbb{R}^3} \min \hspace{0.1 in}&c^Tx+3c^Tc \\ &\text{subject to} \hspace{0.1 in} Ax \leq b \end{align*} Which of the following is an equivalent linear minimization problem...

Homework Statement To preface, I believe this question is equally applicable to either the math or engineering homework forum, but I am having more trouble with the math part than the actual programming. I can't do any programming (with the understanding that linear programming doesn't...

Hello, Can anyone describe what its like going to University of Maryland college park and majoring in physics? Is it true that the teachers there only care about research and don't care about helping you? Also, are the class sizes 150 people (which means you can't get any personalized help)...

"How hard can rocket science be anyway?" Kerbal Space Program is a sandbox type computer game that leans heavily on concepts of physics (don't let that scare you though, you don't need a calculator nor a book of equations to play it. It's ultimately very intuitive). Given the physics nature of...

It's mainly designed for those who want to teach at a junior college or whatever. I plan to stay in oil and gas, and I'm going to take: I'm not concerned about analysis, because I did well in undergrad and have a strong interest in it. However, I took Cal III in 2008, so I'm a bit rusty in it...

Are there any other places that offer engineering physics other than Cornell for masters or PhD? I couldn't find any except applied physics.
