Some of my thoughts on palettes: The principle maxim is: Maximize the functionality; minimize the space. Since screen real estate is valuable there are a few things to be wary of. Don't use a lot of nonfunctional decoration on the palette, or...
This posting is motivated by an earlier posting: [Plotting a specific branch of a multi-valued complex function][1]. However it uses an entirely different method to representi the function, showing the entire function and not just a single branch. ...
The following Mathematica application may be of interest to you. [Grassmann Calculus, Geometric Algebra, Differential Forms][1] [1]: https://davidandalicepark.wordpress.com/home-2/mathematica/grassmann-calculus/
Thanks Carl. That has one minor drawback. It pastes the expression in literally and not as a syntactic unit. Of course, the user could always type a set of parentheses before pasting but might often forget. If it was pasted after a 'z' in an existing...
If you index your points by i you could use ColorData[97][I] for your colorfunc. This gives a distinctly different color for adjacent points on the list but the colors are pretty much random. Look at the Color Schemes palette, 97 under Indexed. This...
I've watched Conrad Wolfram's TED talk and also watched "Making the Case for Computer-Based Math". There is much valuable here. I think the principal message is: Shift the "plug and chug grunt work" to the computer and spend more time thinking about...
With Mathematica 11.1 and Windows 7 I don't see any jitter at any magnification. Nor with extremely fast or slow animation rates.
Yes, I have never understood why Ted's RootSearch code has not been made part of regular Mathematica! In my experience it works very well, finding multiple roots - crossings and zeros, and even though it's specialized to searching along a line this...
a^4 - 4 a^3 z + 6 a^2 z^2 - 4 a z^3 + z^4 % /. a -> y + z // Simplify
The Presentations Mathematica application, which I've developed over the years, has several features that address these issues. One is: HiddenNotebookData[datasymbol, dataname, datavalues] will store the datavalues in a skeleton structure...
