I am sure most of you are aware of the Wolfram Demonstrations Project. If not, it’s a library of interactive models demonstrating different mathematical concepts. If you buy Mathematica you can edit and experiment with the code yourself. I find it really helpful to be able to investigate something in a interactive graph to understand the relationships in say an economic model, e.g. this example of a basic supply and demand model, this more intricate Keynesian IS-LM Model, or this model that allows you to investigate income and substitution effects with different utility functions.

Friendly people here at ask.sagemath have a couple of times answered my questions by posting code to http://sagecell.sagemath.org, which I really appreciate, e.g. this visualization of logistic population growth, but is there a way to search for SageMath code examples or some library of interactive SageMath models demonstrating different mathematical concepts like the Wolfram Demonstrations Project? I'm also interested to share projects myself.

I think something like a SageMath "Demonstrations Project" could be a great way to demonstrate the power of SageMath in an very accessible way, and possibly contribute to spreading the awareness of SageMath.

Update - the second version of the UTMOST grant, combined with the Curated Courses grant, may resuscitate a lot of this - at least for specific course content.

@kcrisman, thank you for the update. Do you have a link to somewhere where I can read about this or could you elaborate what this entails and when such a thing would happen?

@etb - If I understand correctly, the grant mentioned at https://groups.google.com/d/topic/mat... is where this would happen, though I am not privy to all details. Probably a work in progress over the next couple years.

There is an existing set of interact demonstrations at https://wiki.sagemath.org/interact. Unfortunately they have not been updated in some time and are full of deprecation errors.

Though I have fixed at least some of them :) since many just require pretty_print.

@paulmasson, thank you for your response. I forgot about the Interact part of the Sage wiki. Thanks. I recall I looked at it, but it seemed defunct and not like a living community. We should definitely work to salvage the example from there too.

A number of years ago, as part of an NSF grant for improving not just Sage but also open educational resources in general, a website called "interact.sagemath.org" was founded. (You won't find it now, but the Wayback Machine can give you some ideas of what it was like.) The idea was to have something very similar to the Demonstrations project or the Maple Möbius thing (if I recall that name correctly) or Geogebra's very good resources.

This site was used reasonably heavily for a couple years, but curation was a real problem (not enough people voting), and eventually spam was too, so it was first replaced with a placeholder page and then just completely taken down. That particular model did not work well, at least not with the size of curator base we had.

However, one would certainly hope that others have ideas for how to get back to something like this! I encourage everyone to brainstorm.

PS this is definitely not the only answer to this question - there are at least a few usable resources out there now, but I'll let others describe them.

@kcrisman, The Interact project looks very much like what I imagined. I too hope we can get something similar off the ground again, and hopefully we will be able to deal with the curation. Do you know if it is possible to download the whole site or somehow get access to the Sage code? I can’t seem to get it of the site via Wayback Machine.

Huh, that is a good question. I'm not sure if it was archived but I know whom to ask.

@kcrisman, any news in regard to getting hold of the Sage code from interact.sagemath.org? Thanks!

Not yet, sorry.
