Note:These pages make extensive use of the latest XHTML and CSS Standards. They ought to look great in any standards-compliant modern browser. Unfortunately, they will probably look horrible in older browsers, like Netscape 4.x and IE 4.x. Moreover, many posts use MathML, which is, currently only supported in Mozilla. My best suggestion (and you will thank me when surfing an ever-increasing number of sites on the web which have been crafted to use the new standards) is to upgrade to the latest version of your browser. If that's not possible, consider moving to the Standards-compliant and open-source Mozilla browser.

More MathML Entities

Someday, I should go through the list of MathML entities and make sure that itex2MML has conversions from their (La)TeX equivalents. Ugh!, that’ll be a job.

In the meantime, I just keep stumbling on ones which aren’t defined. My last post required me to add \mp → ∓ to the list of known conversions. So here’s an updated version (just the executable was updated, not the MT plugin).

Re: More MathML Entities

Just to let you know, your site slows my Mozilla down to a crawl. :)

Re: More MathML Entities


Really? The SVG graphics in my previous two physics-related posts take noticeably longer to render than the corresponding GIF images (the tradeoff being that they rescale along with the text when you use “Text Zoom”).

But nothing particular has changed about the main page, and it seems to perform perfectly in my copy of Mozilla (1.5b).

What version of Mozilla are you using, and over what sort of connection? I’d like to track down the problem if it’s reproducible.

Re: More MathML Entities

I have a small performance problem on your site with Mozilla (1.5a, Windows 2000, Athlon 800, 128MB) too.

Scrolling your pages (frontpage and entry pages) is very slow and not going smoothly. I know once scrolling in Mozilla acted exactly that way when I had a page with a large jpg image that was set to a smaller size in the XHTML source (height and width attributes). After physically resizing the image the problems were gone.

I don’t see similar usage of images on your pages, but maybe this will give you a hint to the source of the ‘problem’. It could be the fixed background? Maybe I’ll look into it next week.

Fixed background = slow scroll

Yup. Sorry guys. The fixed background image did have an adverse impact on scrolling speed.

So, in deference to those with slower machines, I’ve ditched the background image, in favour of a solid background. Scrolling should be much faster now.

Re: Fixed background = slow scroll

Yes, thank you. Scrolling is much faster now :)
