I've a bad habit and so I nearly dropped from the loo of laughing when starting to read the science-section of the very good German weekly newspaper "Die Zeit" this evening.
It was an article about the decay of the strength of the geomagnetic field, currently some 6.6% per century.
The article in German is here:

The good and serious article is mixed with stuff from and about the movie, in a pretty funny way.
When I have more time, I'll try to translate a few highlights. Until then, you've to stick with babelfish...
