Hi there, I have been using Leonard Susskind's lectures on classical mechanics to learn about Lagrangians and Hamiltonians, and decided to try to create a Lagrangian for the double pendulum and another pendulum-related system. I found the equations of motion, but they were unlike any...

http://oi58.tinypic.com/2d85aix.jpg above is an url to the stats major program at my school. In red are the two classes that overlap. Is it likely that the overlap is intended, or a typo? Do universities ever allow such overlap (an emphasis class overlaps with a core class)? They changed it a...

Did you guys self study or take a class?

I finished my bachelors in electronics and communication in 2014 from India. Since then I have worked as an Application Engineer in the VLSI domain at a reputed company. I would like to transition to Nuclear Fusion Physics. I am planning to give my Physics GRE in October 2015. Some background...

I'm looking for a program or an IDE which generates HTML5 and CSS3 (Would be better if it could generate some javascript too) any suggestions ? I saw some websites like : css3generator.com They are good but i want something that i can use offline and easily accessible

Hi, I made a small program that simulates the motion of a body attached to an ideal spring and released from a horizontal position. Some more info here (especially #1 and #3): https://www.physicsforums.com/threads/equations-of-motion-unsolvable-with-elementary-method.827826/ I've been thinking...

Homework Statement So, I want to make a table and a graph of the multiplicities of a system with two Einstein Solids. I was trying to use Excel but the numbers I guess were too big (300!) being the biggest. There are many more problems I'd like to do where there will be larger numbers too. Can...

A friend asked me to write him a program that contorls a lamp with USB or LAN cable I've seen people using printer cables with Matlab to control an LED matrix .. I use c# as programming language if there is any way or any command that i can use to control it with windows form application or...

I am going to be applying to grad schools in the coming months, and plan to apply to many schools. I'm looking for programs in quantum computation, quantum information, quantum optics, etc... (related research often falls under many different names). These programs generally are categorized in...

Hi, I often hear people say that a certain program (i.e. computer science, maths, etc) is better at one school than at another. For example, here in Canada a lot of people say that if you want to enter into computer science you should go to the University of Waterloo, because they have a...

Hi there, I am having a lot of struggles with program. I am not using this for any true kind of publication but more so we can reference material. However, it is very important that I have a coordinate system where I can plot the WCS. Whenever I try to save as a PNG or JPEG it does not...

PF Family, What is a good way to increase my chances of getting into a joint PhD/JD program. I'm physics major with a 3.86 GPA, a rising junior, and have plenty of math electives (if that helps). I am currently in an REU program at my school, and we are doing climate modeling. I am also doing...

I was wondering if anyone here has a program for their ti-89 that can add and subtract dimension in ff.iiss format. Also it would be great if you could convert ff.iiss to decimal feet and vise versa. For example I would want to enter in 10.0608 (10 feet 6 and a half inches) and convert it to...

Hello to all! I have written this 1D FDTD code but the results I take are very large and after some timestep they get to infinite/NaN... I really don't know what's wrong. The expressions I have used are the exact given solution for the Maxwell equations. Thank you for your help. program yee...

Hello, I have a working calculus library for java and want to use it in a program. I don't have very many ideas. I have limited Calc. II knowledge but a strong understanding of Calc. I. I have an intermediate understanding of java (took 3 courses at my high school of it), and a solid algebraic...

Generally is it as difficult to get into a PhD program in physics during the spring then it is during the fall? I'm asking because many of the schools I'm applying to say that most students are admitted during the fall but they give you the option to apply for the spring as well.

If you are a professor is it better to use Mathematica or Matlab when it comes to publishing papers, which program creates the best graphs. I have origin as well.

SPOILER: This will be a somewhat depressing rant. I like math (or, I THOUGHT I did), but have been feeling incredibly lazy and powerless recently. I'm currently a freshman undergrad, and I just failed Calc III. I've been barely scraping by recently, having gotten a 40 on the first midterm and a...

Hello forum, I am a soon-to-be-graduated Radiation Health Physics student who plans to study medical physics in the future. I have applied for a few schools and I have been admitted to San Diego State's medical physics masters so far. And I am still waiting to hear from Oregon State/Oregon...

Hello guys, I'm a master's here in California and just accepted a job offer for the summer. I will be in charge of a pilot program where I am in charge of 15 students (juniors and seniors interested in science) for 2.5 hours a day, monday through thursday, for 5 weeks. I have to have them...

I was looking at Morehouse, Hampton, and others

I have a master's in physics. I'm looking at PhD programs, but I really don't want to take the same courses over and take comprehensive exams (or the damn GRE). I managed to squeeze in a few math classes before I finished. I would like to do research in physics, but from a more math-heavy...

Hello, I'm not sure if this forum is the right place for this. My son is a Junior in High School, he wants to have a career in Physics. We have been trying to find the right school for him in the northeast, where we live. It has been difficult, however, to determine which schools have great...

Hey guys, I was an average physics major as an undergrad who entered medical school. I graduated from undergrad about 4 years ago and have been inundated with medicine since then - so I haven't had much of a chance to review old mathematics and physics. I will be starting an MS in BME in August...

Hi everyone, Long time lurker here coming out to make my first post. I just finished my B.Sc. in Physics and I am getting ready to apply to graduate schools in the Fall of 2015. I did some undergraduate research in experimental biophysics (understanding the statistics of the transport of...

This is a little toy I put together that I thought might be of interest: http://ibises.org.uk/Minkowski.html It's an interactive Minkowski diagram. You can add events and connect them up with straight-line paths, then Lorentz boost either to a specified velocity or to the rest frame of a...

Hi, I'm using MATLAB R2011a in my project, involving matrices of dimensions up to (70 × 20). I had good results, a time ago. Currently, poor results are generated using the very same code -(of good results)- with same parameters settings & relatively smaller matrices (30 × 20) ! I tried...

If I have program X how do I get it in binary form?

Hello everyone, I graduated with a BSEE in 2008 and tried a PhD program in EE (semicon device specialization) for a while but it didn't work out. I struggled with an illness that forced me to drop out. I have been working in industry (NOT The semicon industry) since leaving the PhD program...

Write a Java program to find the sum of all numbers between 1 to 10. So we all know that 1+2+3+4+5+6+7+8+9+10=55 and that answer to this problem is 55. Please check my work below: public class Standard { public static void main(String[] args) { // Create a for...
