The Möbius Project

Francis Wright, July 2014


The Möbius Project is a recent Maplesoft initiative to provide “a new way to bring Maple technology to the classroom”; see It provides free teaching materials in the form of Möbius Apps or Math Apps. To run Möbius Apps you only need a web browser and/or the Free Maple Player or Maple. (To create Möbius Apps you need Maple but to run them you don’t.) Running Möbius Apps in a web browser is not ideal, so for anything more than very casual browsing I recommend using Maple Player or Maple, either by downloading the Möbius App and opening it from your local file store or via MapleCloud. Maple Player is also available for the iPad – see – but not yet for Android.

This session is completely open-ended and is intended to provide you with an opportunity to explore a few Möbius Apps to see whether they would be useful in your teaching. Maple Player is essentially a restricted version of Maple and because we already have Maple installed on the Queen Mary computers we have not also installed Maple Player. The main point of Maple Player is to use it on computers that do not have Maple installed. So this afternoon you need to use Maple instead of Maple Player (unless you are using your own computer).

Browsing and running Math Apps using Maple

Möbius Apps within Maple are called Math Apps. Since you have access to Maple, I recommend that you start by looking at the Math Apps that are built into Maple.

Start Maple, open the Help menu, then the “Manuals, Resources, and more” submenu and select Math Apps. This will open a help page that gives access to all the Math Apps built into Maple. Beware that each app is represented pictorially, so expect a short pause while Maple renders all the images. Then just click on a Math App to open it in Maple, which is equivalent to downloading and opening the corresponding .mw file (see below). There are quite a lot more apps available in Maple 18 than in Maple 17.

Browsing Möbius Apps via the web

You can browse and search all Möbius Apps at but it is probably better to start by looking at the Top 25 Apps you can use in your class today or the selection of Möbius Apps for Students. To run a Möbius App in a web browser just click on the link to the app as usual, but then be prepared to wait while the Java support required downloads, which can be quite slow. You should see a dialogue that says “Do you want to run this application?” It should be safe to click on the Run button if you have accessed a Möbius App from the Maplesoft web site. You should then be able to interact with the app, primarily using the mouse. There should be instructions within the app that explain what it does and how to control it. However, beware that the quality of the maths displayed within a web browser depends greatly on the browser (and possibly the underlying platform).

Unfortunately, in my experience, opening or running Möbius Apps in a web browser does not always work, but it is a good way to see what is available. It should show you roughly what an app is about and allow you to decide whether it is sufficiently interesting to be worth downloading to run in Maple or Maple Player (which will run the app correctly). For me, using Windows 7 and the latest versions of various web browsers, Google Chrome runs Möbius Apps quite well, Mozilla Firefox works sometimes and Internet Explorer doesn’t really work at all!

With a Möbius App open in your web browser, if you click on the Download link under App Tools to the left of the app itself then you will download the corresponding Maple document as a .mw file. If you then open this document it should open automatically in Maple or Maple Player provided one or the other is installed appropriately. If Maple displays an autoexecute warning then you need to allow autoexecution.

There is a Booles Math App on the course web site that I wrote. It is a game to test your ability to evaluate Boolean expressions.

Browsing and running Möbius Apps via MapleCloud using Maple or Maple Player

Expand the MapleCloud palette if it is collapsed (and in Maple turn on MapleCloud in Options if it has been turned off). Select Maplesoft@admin in the drop-down list below the search box. Select either the Popular or the New tab; I recommend starting with the Popular tab. Scroll through the list of apps using the up and down arrow buttons on the right below the list of apps. (Note that some facilities require you to log in but you don’t need to log in to run Möbius Apps.) Double-click an app to open it. Expect a pause while the app downloads and then it should run just like a built-in app in Maple.

You can search MapleCloud for apps by selecting the New tab (only), typing a word or phrase, and pressing the Return or Enter key.

Writing Maple Math Apps

Full details about how to write Math Apps are provided in the Maple help system, which can also be freely accessed online at You can access the source code of any Math App if you open it in Maple (but not in Maple Player). Most Math Apps are structured as tables containing embedded GUI components that communicate with each other via Maple program code. Once you have written the code to implement the mathematics, which one would normally do first, it is not a lot more work to add the code necessary to create the app. In fact, Maple can create simple Math Apps semi-automatically by using the Explore command.

Having written a Math App you can upload it to MapleCloud as a Möbius App; see the Maple help for details.

Teaching Concepts with Maple

The Teaching Concepts with Maple web page provides video examples and downloadable Maple documents designed to help your students learn concepts more quickly and with greater insight and understanding.
