## The mysterious equilibrium of zombies – The Boston Globe

After a thorough, if tongue-in-cheek, analysis, the authors found that the optimal method for halting such epidemics involves killing zombies early and often – the rare scientific paper that satisfies both the splatter-film aficionado and the Centers for Disease Control.

## Mathematics ITP: Fractions

he Fractions interactive teaching program (ITP) is an ICT-based tool to support the exploration of part numbers. Fractions ITP allows the child or teacher to represent and compare fractions on fraction strips. The displayed strips can be labelled as a vulgar fraction, a decimal (to three decimal places) or a percentage, and the ratio of yellow to green parts of each strip can also be displayed. The application (in a variety of formats) and guidance for using the application (as PDF or Word file) can be downloaded from this page

## Crochet & Kindergarten for Grown-ups

I love this. And I love the idea that abstract mathematical concepts can sometimes best be understood by tactile, asymbolic play.

## Empirical tags experiment

Looks like Prof Chuck and his graduate student might be about to do an interesting experiment.

“a study where we compare information retrieval times and errors when people are using 2 kinds of info organizations: traditional hierarchical/taxonomic categories versus tags.

Between groups: We are thinking of having subjects come in and sort 100 photographs into categories or tag 100 pictures. Then, a few days or one week later, they would have to retrieve a subset of those pictures. Of course we would control the amount of time spent on the pictures.”

It got me thinking about maths proofs of the same problem. Presumably, you could do some statistical analysis of the problem? And that might let you know something about the relevant pro’s and con’s, of say how many tags to use?

(This all then made me realise how much maths I’d forgotten or never knew, but anyway, here goes some thinking out loud…)
