Personal Stories

Stories about how you have used Maple, MapleSim and Math in your life or work.
Yesterday I downloaded and installed the latest upgrade to Maple 10.05 for OS X. Today I find that I can open two worksheet sessions, but not a third. Opening a third file takes ages (approx. 30 sec) and when I try to execute the file, I get the message "Waiting for kernel connection." This behavior is consistent over several tries. I have a Power PC with 1 GB SD RAM. Has anyone else seen this behavior?
To mark the end of eleven very fruitful years in residence at the University of Waterloo, I have written a goodbye essay. The title and abstract appear below, along with a link to the full text. The essay describes my long-term research goals and presents my personal vision for the future of the areas of mathematics in which I work.

With mapleSTUDIO you can plot functions in 2D and 3D. Animating your plots won't be a problem any time. This is the easiest way to plot your functions.
You can use it here online on mapleNET or you can download it and run the worksheet on your Computer. For adding new components to this worksheet I will only change the file on mapleprimes, but the name and the URL will be the same. So you should bookmark the mapleNET-URL for using the newest version of mapleSTUDIO. You can also add my Blog to your Feed-Reader, so you will know, when a new version is available.

Ten days playing with Maple has proven that skills in one system don't necessarily translate to another. I have encountered a number of frustrations which are not so much a problem with Maple as my inability to match the subtleties of the new system. Some of the issues I have encountered:
  • periodic locking up of the interface in document mode (this may be due to something I am doing wrong)
  • getting used to the maple syntax and command list (it is further than the syntax of Mathematica than I originally suspected yet similar enough to completely mess me up)
  • occasional odd state like behavior (which is, again, probably due to my ignorance than a problem with Maple)
These are the notes of a new Maple user attempting to come up to speed in, what is for me, a new algebraic manipulation tool. I am looking at the tool not so much as an engine for solving problems as much as I am interested in using it as a tool for teaching advanced physics concepts to students in the secondary school arena. Right now I only seek to use it as an aid to building better presentations for the students as well as supplying a dynamic environment for solving problems for students in my class.
After read this funny post by Will, I implemented a short function in Matlab (linked to Maple) to count the number of occurences of any number into the 10.000 first digits of Pi. Here is the result for the first 9.999 numbers:

Well, I'm now the proud owner of the student version of Maple 10. The graphing calculator is neat, and I'm having a blast learning the Maple interface.
Hi everyone! I want to thank Tom Lee for inviting me to join the MaplePrimes community. I feel very enthusiastic about the creative potential of this wonderful collaborative resource and want to take a moment to introduce myself. My first blog post includes a brief biography and states some of my Maple plans and research goals.
I have met several problems trying to install and execute Maple on Fedora Core 4. I begin with Maple 10. Default GUI installation does not work: ============== [root@localhost cdrecorder]# ./installMapleLinuxSU Preparing to install... Extracting the JRE from the installer archive... Unpacking the JRE... Extracting the installation resources from the installer archive... Configuring the installer for this system's environment... awk: cmd. line:6: warning: escape sequence `\.' treated as plain `.' Launching installer... Invocation of this Java Application has caused an InvocationTargetException. This application will now exit. (LAX)
I'm just curious - and I don't work for Maplesoft :) - but what do people here actually use Maple for ? What sorts of problems are you tackling, and what commands/packages do you typically use ? I'm also interested to hear about how people use Maple in teaching (for those that do). Myself I use Maple for research in computer algebra - mostly topics related to polynomial systems. For example, I may be trying to find algorithms to compute in new domains. I like Maple because it is very easy to program mathematical algorithms. It is not quite so easy to get them to run fast, but that gives me something to work on :) I mostly use my own software (PolynomialIdeals + recent code), but I also use the Groebner package and now the RegularChains package (new in Maple 10). I make a point of trying all the other packages every once in a while, since you never know when something is going to be useful. I use the plot commands a lot as well.
Hello All: I am working on generating some correlated sequences using Matrix Exponential techniques. there seems to be some problem with the way maple manages memory (or am i doing something wrong?). specifically, in the code below, i am calling a few functions inside a for loop but none recursively. so as the for loop progresses my stack (memory; seen as PF Usage in win XP) size should not really blow up. right? but in Maple 9.0 and 10.0 this below program would give a "Execution stopped: stack limit reached." exception after about 30000 executions(I am running on a WinXP machine , about 2.8GHz, with 512 MB RAM, also checked on a machine with 1 GB Ram; and another 1GB in page file size). But the same program seems to work alright on the same machines with Maple8 running (i uninstalled maple-9 and installed maple-8 in one case). I could go up to 300,000 iterations without any problem. And the memory would go from about 250MB (PF Usage) to about 800MB. So even in Maple 8 there is some stuff that is being dumped on the stack; i tried to run Garbage collector (gc()) function once every 500 iterations; it did not make any difference either. Can anyone please look into it?
The University of Toronto is Canada's largest university and considered one of its very best. Its downtown campus (St. George) campus is the original site with all of the older buildings (circ. mid 19th century) and most of its most prestigeous faculties. Of note for the math crowd would be the Fields Institute .
I was doing some stuff with the quadratic nonlinearities that interest me. The quadratic nonlinearities involve structure having the form <>, where <> represents the usual dot product, A is a matrix, and v is a vector. I didn't want to use complex numbers with what I was doing, so I assumed things were real valued. I was surprised by what happened as a result. I have simplified the curious behavior so that it can be observed in a few lines. I can live with this, but it was a surprise.

This recommendation was provided by Dr. Jürgen Gerhard, a colleague of mine at Maplesoft and coauthor of the book Modern Computer Algebra. He felt that Göttingen was definitely a center for German mathematics and science and well worth the visit if you are mathematically inclined. The city is located virtually in the geographic center of the country (in the state of Lower Saxony...
