As a federation of 10 physical science societies, The American Institute of Physics (AIP) pursues a mission to advance and distribute the knowledge of the physical sciences and its applications. AIP Member Societies collectively represent more than 120,000 scientists, engineers, educators and students in the global physical sciences community.

“The continued support of AIP Publishing demonstrates its commitment to being a partner to the science community”, comments Peter Krautzberger, MathJax manager. “The feedback of sponsors such as AIP is invaluable to ensure that MathJax remains the reliable, high-quality rendering solution it is today.”

“We believe MathJax provides a valuable service to researchers in the physical sciences by taking the worry out of accurately displaying and easily sharing the mathematical equations that are so important to the research they do,” said John Haynes, CEO of AIP Publishing.

We look forward to continuing the collaboration with AIP, and welcome their ongoing support for the MathJax project.

]]>*Here is our fourth interview with interesting people in the MathJax community. This time we had the pleasure to talk to Wonseok Shin (Stanford University) about jemdoc and jemdoc+MathJax.*

*You recently extended jemdoc to create jemdoc+MathJax. Can you tell us a bit about jemdoc and your work on it?*

jemdoc is an open-source static site generator that allows you to create simple websites. It is composed of just a single Python script, so it is extremely lightweight and portable.

jemdoc was developed by Jacob Mattingley while he was a Ph.D. student at Stanford University. I guess he developed jemdoc to create his personal academic website easily. In fact, jemdoc is most commonly used to create university professors’ personal websites that introduce their research and teaching experiences. (If you google “jemdoc”, you will see a bunch of professors’ websites.) It is also being widely used to create university course websites.

In addition to being lightweight and easy to use, the ability to load LaTeX equations has been one of the reasons for jemdoc’s popularity in academia. However, the original jemdoc loads LaTeX equations as PNG images, which can be pixelated on high-resolution displays or upon magnifying the webpage.

I have modified the original jemdoc to support MathJax. The modified jemdoc is called jemdoc+MathJax. If you are already a jemdoc user, you don’t have to change anything in your *.jemdoc files. By simply replacing jemdoc with jemdoc+MathJax and processing your *.jemdoc files again, you create a new website in which all PNG equation images are replaced with beautiful MathJax-rendered equations.

*Why choose jemdoc’s markup language over other lightweight markup solutions like markdown or textile and how does jemdoc fit into this ecosystem?*

To me, it made perfect sense to implement MathJax support in jemdoc than in other markup solutions, because jemdoc is already being widely used in academia, where mathematics is the primary language to communicate ideas and therefore equation rendering is highly demanded.

For general users, the biggest difference between jemdoc and other markup solutions could be that it creates an entire website (including a navigation sidebar) rather than a single webpage. Therefore, if you want to create an entire website from scratch, jemdoc can be a better choice than other markup solutions.

Being able to generate an entire website makes it very easy to migrate from one web server to another, because you can simply move the HTML files to the new web server. Again, this is a useful feature for people in academia. For example, if you create your personal website as an undergraduate in one university and seek for more advanced degrees in another university, you can easily move your entire website from old university’s web server to new university’s by moving the HTML files.

*Can you tell us a little bit about your background?*

I did my Ph.D. degree in Electrical Engineering at Stanford University, and I am currently a postdoctoral scholar in the same university. I have developed my programming skills through my previous experience as a software engineer at a startup company, and also through my doctoral research in which I studied electromagnetic phenomena by numerical simulation (which involved a lot of programming).

Around the time I was finishing up the Ph.D. degree, I felt a need for a neat personal website to introduce my research more efficiently to my fellow researchers. I tested several static site generators, and jemdoc stood out with the built-in LaTeX equation support because I needed to use equations to describe my research. However, I was disappointed with the quality of the rendered equations in jemdoc. I knew about MathJax already, and really wanted to use it, but failed to find an existing MathJax implementation in jemdoc. So I spent some time to implement MathJax in jemdoc myself.

Originally, the MathJax support was a personal project that I intended to use only for my personal website. I uploaded the modified code at Github anyway for my own convenience. One day a complete stranger who saw my Github repository contacted me and asked if I could teach him how to use MathJax in jemdoc. That was when I realized other people’s interest in using MathJax in jemdoc. So I polished the code, added concrete examples for the additional features I implemented, and named the project jemdoc+MathJax.

*Who do you see as the primary users for jemdoc+MathJax?*

The primary users would be the previous jemdoc users. As I mentioned earlier, you don’t have to change anything in your *.jemdoc files. By simply using jemdoc+MathJax instead of jemdoc to process your *.jemdoc files, you create a new website with nicer-looking equations.

People who want to create a simple website with lots of equations, such as mathematicians, scientists, and engineers in academia, will also find jemdoc+MathJax useful, even if they haven’t used jemdoc previously.

*Mathematical markup is not naturally “lightweight”. What are your thoughts on the future of mathematical markup on the web?*

I think mathematical markup will become more popular in the future. Massive open online courses (MOOCs) such as Coursera and EdX will be major driving forces. There, students need to submit their homework solutions on the web. However, assigning math and science homework problems is currently difficult in MOOCs, because most homework problems in these subjects require equations as answers, which are hard to input on the web. With an easy-to-use mathematical markup system, testing students’ knowledge on math and science subjects in MOOCs will become much easier.

*With static site generators, hosting becomes easy but web-based authoring isn’t straight forward. Any tips for jemdoc users who want the best of both worlds?*

Unfortunately, there is no web-based authoring system for jemdoc currently. Using jemdoc requires some familiarity with UNIX-like operating systems.

However, if you have a bit of experience on UNIX-like operating systems, using jemdoc is quite straightforward. You first write down the contents of webpages in jemdoc’s Markup language, which is similar to Markdown, and store them as text files, typically with “.jemdoc” as the filename extension. (Each .jemdoc file describes a single webpage in your website.) Then you process the .jemdoc files with jemdoc to convert them to HTML files. The generated HTML files constitute your website. You can simply upload the HTML files to your web server’s dedicated folder under your account to make your website running.

Detailed usage of jemdoc can be found in jemdoc’s official website at http://jemdoc.jaboc.net. Note that the official website itself is created completely by jemdoc.

*What are your (near or long) term plans for your work on jemdoc+MathJax?*

I use jemdoc+MathJax for my personal academic website, and I don’t see a particular feature that I need immediately, partly because jemdoc itself is already a pretty mature system with many useful features. There were some lacking features such as drawing underscores in the original jemdoc, and I have already added those features in jemdoc+MathJax, whose usage are explained in detail in the example files included in the jemdoc+MathJax package.

I will respond to any bug reports and feature suggestions as much as possible. Also, jemdoc+MathJax is open-source and the source code is publicly available as a GitHub project at https://github.com/wsshin/jemdoc_mathjax. I hope other people contribute to jemdoc+MathJax, as I did to the original jemdoc, to implement useful features.

]]>MathJax v2.4 is available on the CDN, and for download from GitHub; see the documentation for details.

Version 2.4 is available on the CDN at

and **starting today** the files at the

address will be switched over the v2.4; it might take a few hours for the changes to propagate out to the distributed cloud servers.

During the time that the files are making their way out to the CDN’s servers, there may be a mixture of files in a browser cache, and so users may need to clear their cache and restart their browser in order to get a consistent version of the files.

If you are a page author and concerned about this, you can change (temporarily) to the `mathjax/2.4-latest`

URL instead of `mathjax/latest`

since that is a new address that will not have any cached older versions to worry about. You can switch back to `mathjax/latest`

in a few days when the new version has migrated to all the locations in the cloud.

See http://docs.mathjax.org/en/v2.4-latest/whats-new-2.4.html for details about the changes in v2.4. We anticipate a smooth upgrade from v2.3 to v2.4, but as always, let us know on the bug tracker if you experience problems with this new version of MathJax.

Thank you for your continued support.

The MathJax Team.

The beta is available via our CDN at beta.mathjax.org/mathjax/latest/MathJax.js which you can load it in place of the version you are currently using; **note** this address can be accessed as via both *http* and *https*.

Alternatively, you can get a ZIP archive to use locally or you can check out the `v2.4-beta`

branch of MathJax by using the commands

```
git clone git://github.com/mathjax/MathJax.git MathJax-2.4-beta
cd MathJax-2.4-beta
git checkout v2.4-beta
```

at an appropriate location on your server.

**Remember that this is still beta software**, so if you are not an experienced user, you may want to wait for the official 2.4 release. We do not recommend that you use the 2.4-beta version for production environments, but do encourage you to test your sites with it.

If you are linking to http://cdn.mathjax.org/mathjax/latest/MathJax.js, note that at the point of the official release of v2.4, the address will begin to serve MathJax v2.4. You can also continue to use v2.3 by linking to http://cdn.mathjax.org/mathjax/2.3-latest/MathJax.js instead — and you can change to that version at any point (it is available now). Once the official v2.4 release is made, the v2.4-beta address will be removed from the CDN.

The official release of v2.4 should occur within the next three weeks, but we want you to be able to start to test out the v2.4 features now. Please report any bugs you find to the issue tracker at https://github.com/mathjax/MathJax/issues.

Thanks for your continuing interest in MathJax. We hope that this release makes your MathJax experience even better.
