This site is best viewed through a modern browser. Our browser support policy is similar to that of Google for its “Google Apps” products. More specifically, we support the current and previous major releases of Safari, Chrome, Firefox, and Internet Explorer. Each time a new version of these browsers is released, we begin supporting the new release and drop support of the oldest previously supported version.
This policy is not as draconian as it may seem. We don’t go out of our way to break previously supported browsers. Rather, we just quit testing changes to the site on the older products. Typically, many older versions of Safari, Chrome, and Firefox work quite well with this site. The same statement does not hold for Internet Explorer. Currently, Internet Explorer 10 and 11 are supported. Internet Explorer 9 works reasonably well. Legacy versions of Internet Explorer (IE 8 or earlier) are problematic. Most of their difficulties are primarily due to their lack of support for modern CSS facilities.
A note for Opera users. Although not formally supported, we do inspect the site through Opera from time to time. We are not aware of any glaring issues when viewing the site with recent versions of Opera.
We have expended some effort to provide a pleasant experience when viewing this site on mobile devices. However, we must contrain that statement by the word Apple. We don’t have a philosophical objection to Android or Windows mobile devices. We are just an Apple shop and don’t purchase other vendors’ devices for testing. That being said, we aren’t aware of any theoretical difficulties to viewing our content with recent non-Apple mobile browsers. No Apple specific techniques were used when coding this site.
Mathematical content on this site is encoded using presentation MathML.
MathJax provides web fonts for math rendering, so no font installation is required on the browsing device. If you have the STIX fonts installed locally, MathJax will use them. This will speed up math rendering somewhat, since the web fonts don’t have to download.
Our article Viewing Mathematics on the Internet thoroughly examines the current state of online math publication and browsing. Its introduction provides a summary of the status of MathML rendering by browser. The concluding remarks examine additional aspects of publishing/viewing mathematics on this site. In between, a variety of relevant topics are thoroughly investigated.
This site is served as HTML5. We previously served our content as xml/xhtml to browsers that provide xml support. We changed our policy since it seemed that was not the direction the internet was heading.
