| Is there any chance that a seriously interested (but still home based) person can use MMA to check the latest claimed, largest Mersenne prime? My machine just overheats? |
| I am trying to calculate the electric field potential above a charged, insulating, disc. The simple version has the potential evaluated along the y-axis if the disc lies in the x-z plane and centred at the origin. In polar coordinates the integral is... |
| Hi I am looking at some simple electricity and magnetism problems and want to use various tools to look at the electrostatic vector field. In my attached (M10) notebook I try to use ListStreamPlot and ListVectorPlot as alternatives to do this. I can... |
| I am working with tensors for the first time and am trying to solve some simple problems with the inertia tensor in 3-D. All goes well until I try some simple coordinate system rotations using the RotationMatrix function. I have built a very simple... |
| I am teaching myself simple classical mechanics and have a model of a particle moving in a central,conservative force field in 2D. As a function of time, I can plot the radius vector (nice ellipse as expected) or the velocity vector (...). What I... |
| Hi, I am trying to learn how to use the EquationTrekker package inside Mathematica 10.0.02. As soon as I try and run even the simple example from the documentation centre, I just get a some very strange error messages. I have attached the example... |
| In a simple study of a chaotic system (spring pendulum) I am looking at a variety of ways of presenting my results. One of the simplest should be a series of time snapshots of the pendulum bob position. I use NDSolve to get a function that returns... |
