| Ok, there is a lot to say here, but I should first of all say that I am not really an expert. I think that there has been some implementation of nonstandard analysis in the Wolfram language, although I cannot remember where. About using Wolfram... |
| ![enter image description here][3] - Congratulations! This post is now a [Staff Pick][1]! Thank you for your wonderful contributions. Please, keep them coming! [1]: http://community.wolfram.com/content?curTag=staff+picks [3]:... |
| Thanks everyone. I woke up in the middle of the night realizing that `NotebookImport[Notebook[AllCases[expr,_Cell]]` would work. Only learned about NotebookImport a few days ago although it's been around for a couple years. |
| Thanks for your replying, Mr. Lichtblau! **Your suggestion completely solves my problem** and I can finally relieve a little bit now. Since I am beginner to Mathematica, I did not realize the difference between 0.01 and 1/100. Really learnt something... |
| This paper shows the relationship between complexity and the graph automorphism group size: Correlation of Automorphism Group Size and Topological Properties with Program-size Complexity Evaluations of Graphs and Complex Networks H. Zenil, F.... |
| Thank you, Daniel! I found an exhaustive explanation on the $Wolfram MathWorld$ page: [Cube Root -- from Wolfram MathWorld][1] > The schoolbook definition of the cube root of a negative number is (-x)^(1/3)=-(x^(1/3)). However, extension of... |
| They are really cool videos. As a suggestion, I would end up with an image of a resume of the concepts or the functions you just talked about. Students could stop and copy those great useful functions and try to use them after. Please keep on... |
| Hi Todd, There's a wide variety on interest. A lot of the time I side with you. The Lorenz equations, for example, are non-linear, chaotic differential equations. Others are not so high minded, and don't care if you can produce an oscilloscope... |
| Hello, Kind of a related question. But what if I am trying to Repeat Calculations/Iterations without a specific function? I am trying to repeat an initial condition many times such that I get a desired final output. ONE final output depends on... |
| Hi Moderation Team, Thanks for the plaudit! But if we're going to make this a featured post, let's go ahead and add an animation. Performing standard numerical time evolution along the pendulum C.E.S. allows us to compute a "phase space... |
