I could not attend this year the full week of workshops and conferences, including MKM 2008, and going on now in Birmingham but I found out that the Jacobs JEM partners are there and are blogging about it. I found this because I was going through the posts archived under Planet JEM.

After reading Murray's blog and getting the invitation ID, I managed to download the stylesheets that should convert OOML to MathML2.0. Now I just need to figure out how to get these working on the parallels installation of Word.

To properly understand Stokes' theorem, it is useful to recall a few basic notations and results from calculus.

These notations and results refer to the gradient of a function, to the curl and divergence of a vector field, and to a few fundamental relations among them.

In this chapter the learner will find the basic facts about line, surface and volume integrals that we will need.

I have been using the Zemanta firefox plugin for a while now and now the Drupal module is installed on the JEM portal. Zemanta uses the semantic web to scout for images and links that might be useful when you are writing a blog entry. I think the idea is a good one and worth of explorations from the point of view of mathematics, say by integrating search engines and smart scientific text analyzers to suggest possible connections.

I got wrong advice. Or perhaps I asked a wrong question.

I am right now taking part in the ICME 11 conference, the most important international meeting of mathematics educators. ICME conferences meet every four years. This time the meeting is taking place in Monterrey, Mexico. Together with Olga Caprotti I organized a workshop entitled eLearning Mathematics and participated in the activities of the meeting in general.

I have been creating Podcasts using Keynote and iMovie. This has been working fine, and I have created podcasts that cover a basic calculus course completely.

Yesterday I needed to create another podcast. I started my Keynote, produced and recorded the presentation, and exported it to Quicktime. But no sound. The recording did not play anymore when the presentation was exported to Quicktime.

I found out that the culprit was the new version (4.5) of Quicktime. See

Did you notice the live feed monitor, on the left column, under the "Online Now" header? We just added it yesterday to show you how traffic comes to our JEM pages, what pages are hit mostly, by which search phrases (some puzzling ones too). You can also see the map of the traffic, generated live.
