Hi, I am interested in simulating the vacuum field equations, but solving a full boundary value problem rather than the initial value problem. i.e. I might have boundary conditions in all spatial and temporal extents/extremes, rather than just an initial 3D surface. Does anyone know any free...

I'm currently enrolled in a MechE course, at my third year, and it took a long time to discover that this is not the major for me. In my spare time, I've been learning electronics (Arduino) and programming, and I decided that I like this stuff better than my MechE classes. Most of my interest...

What is the best software for the analysis of chaos in electric circuits.

I have a project and in that project I'll count the wild life animals from a drone. I need to find a drone that doesn't make much sound also (maximum 60-70 dB), it must capable of a flight time 30 min and also can carry a IR camera. I find a drone callled Phantom 4 (Advanced or Pro)...

I'm at the third year of my MechE course, and in those three years I've developed a keen interest in software/coding. I still like my degree, things like fluid dynamics/aerodynamics fascinate me, but more and more I see myself working with software and coding. One of the things that I like about...

I am 26 years old and I recently went back to school to study computer science - I hope to graduate by 2019 with a BSci. I'm currently interning as a software engineer as well. I was curious what opportunities there are for software developers to work around physicists, astronomers, etc. My...

Hi there, I am wondering if you have any suggestions how to draw these simple engineering models? Thank you in advance.

I'd appreciate it very much if someone told me if there is any free software to (draw and) calculate the amplitudes of simple (tree and one loop) Feynman diagrams. I'm hesitating because I don't know if this is the right place to ask. If it's not, I apologize in advance.

What is the software that has this kind of plot: I want to use it for plotting graphs because it looks clean. Thank you in advance. Edit: To avoid confusion, I want to know what software produces this graphing style, not the kind of plot.

Looking for software for drawing biological processes and pathways between cells or even tissues. I have engineering/programming/control systems experience so I am looking for something similar in biology. The ability to define different things, different colors or shapes would be good, I...
