Some rights reserved under creative commons license.Tue, 21 Feb 2017 14:35:32 -0600where is the SageMath "Demonstrations Project"?http://ask.sagemath.org/question/35347/where-is-the-sagemath-demonstrations-project/I am sure most of you are aware of the [Wolfram Demonstrations Project](http://demonstrations.wolfram.com/topics.html). 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](http://demonstrations.wolfram.com/BasicSupplyAndDemand/), this more intricate [Keynesian IS-LM Model](http://demonstrations.wolfram.com/TheKeynesianISLMModel/), or this model that allows you to [investigate income and substitution effects with different utility functions](http://demonstrations.wolfram.com/IncomeAndSubstitutionEffectsWithDifferentUtilityFunctions/).
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](http://sagecell.sagemath.org/?q=uwecsj), 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.

http://ask.sagemath.org/question/35347/where-is-the-sagemath-demonstrations-project/?comment=36688#post-id-36688@etb - If I understand correctly, the grant mentioned at https://groups.google.com/d/topic/mathbook-xml-support/88lgEHOQ348/discussion is where this would happen, though I am not privy to all details.

http://ask.sagemath.org/question/35347/where-is-the-sagemath-demonstrations-project/?comment=36659#post-id-36659Update - 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.Sat, 18 Feb 2017 16:51:48 -0600http://ask.sagemath.org/question/35347/where-is-the-sagemath-demonstrations-project/?comment=36659#post-id-36659Answer by paulmasson for <p>I am sure most of you are aware of the <a href="http://demonstrations.wolfram.com/topics.html">Wolfram Demonstrations Project</a>.

http://ask.sagemath.org/question/35347/where-is-the-sagemath-demonstrations-project/?answer=35357#post-id-35357There is an existing set of interact demonstrations at https://wiki.sagemath.org/interact.

http://ask.sagemath.org/question/35347/where-is-the-sagemath-demonstrations-project/?comment=35377#post-id-35377@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.Thu, 03 Nov 2016 03:12:44 -0500http://ask.sagemath.org/question/35347/where-is-the-sagemath-demonstrations-project/?comment=35377#post-id-35377Comment by kcrisman for <p>There is an existing set of interact demonstrations at <a href="https://wiki.sagemath.org/interact">https://wiki.sagemath.org/interact</a>.

http://ask.sagemath.org/question/35347/where-is-the-sagemath-demonstrations-project/?answer=35349#post-id-35349A 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](https://web.archive.org/web/20141002043432/http://interact.sagemath.org/top-rated-posts) 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.Wed, 02 Nov 2016 07:54:04 -0500http://ask.sagemath.org/question/35347/where-is-the-sagemath-demonstrations-project/?answer=35349#post-id-35349Comment by kcrisman for <p>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.

http://ask.sagemath.org/question/35347/where-is-the-sagemath-demonstrations-project/?comment=35376#post-id-35376@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.Thu, 03 Nov 2016 03:05:55 -0500http://ask.sagemath.org/question/35347/where-is-the-sagemath-demonstrations-project/?comment=35376#post-id-35376Comment by kcrisman for <p>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.
