This is really neat, Silvia. I hadn't seen the original post. I like the way there are two frequencies going in- and out-of-phase, giving a variable beat frequency, and the illusion of rotation. |
Very nice! Please see if the new [CompartmentalModeling][1] paclet can make your teaching easier. I'd be more than happy to work with you to that end. Bob [1]:... |
That is really strange behavior, and I consider it a bug. The easiest work around is to split the work into two parts using `Show`, putting everything except the lines in the first part, and only the lines in the second.: data =... |

If you take a look at the video that [@Ron Gove][at0] linked at the very beginning of this thread you can get a pretty good idea of the computability that can be achieved. I'm sure there is much that can be done. [at0]:... |
Without loss of generality, we can work with 2-dimensional matrices. The Abelian group of order 3 has these elements: ``` In[429]:= A3 = {IdentityMatrix[2], RotationMatrix[2 \[Pi]/3], RotationMatrix[4 \[Pi]/3]} Out[429]= {{{1, 0}, {0,... |
It's amazing where our thoughts come from. As from out of the blue while reading a book about a beech wood in England I realized that both myself and Danny overlooked that fact that the space groups are infinite groups. And because they are infinite,... |
Clustering relies on a single measure of "distance" between objects, so it's just a matter of devising a reasonable way combining several distances (one for image data, one for physical measurements, one for pollinators, ...) into one. It is... |
Because the package file is autogenerated from the notebook, every time the notebook is saved, the package file gets rewritten. Therefore one should _never_ edit the package file. Regarding conversion of a code file (script or package) into a... |
The endemic equilibria can be found with `Solve`, the way you have been trying. I may just take a long time to get a fully symbolic solution. Unless you want to prove that an endemic equilibrium is unstable when R0 |
