Not so crazy pairings

Last month I wondered why a small village in Cambridgeshire should be twinned with the celebrated German city of Weimar. Now comes an email from the eagle-eyed James Miller who reveals that

The “Weimar” twinned with Sawtry is not the grand seat of European culture.

In fact it’s a small district about 10km south of Marburg, in Hessen, on the river Lahn.

The main town is Niederweimar (try Googe images).

It’s nice to have these puzzles solved.

Taxation and mobile phones

This week’s Economist has a fascinating report of research into the way mobile phones are taxed in developing countries. The findings are summarised in this chart.

The conclusion is obvious: there’s a strong inverse relationship between consumer take-up of the technology and the level of taxation. And it exposes a wider tragedy, because there’s no doubt that wide dissemination of mobile phones could be an important driver of innovation in countries with poor fixed communications infrastructures.
