Wednesday 14th September 11

Well a good day... spent the morning with our eldest son who was off school, watching a really interesting video, explaining how to understand annual percentage growth rates and the exponential curve.  We both really enjoyed it, and I feel it is an important concept to understand if you class yourself as 'green', or use the word 'sustainable', or enjoy a bit of maths, or are involved in public policy.  It renewed my belief in having a zero growth economy.  It is truly the only way we're going to get through the next few decades.  It also features the work of one of my favourite oil scientists, M. King Hubbert.

I'm looking for resources with which to illustrate my Cafe Scientifique presentation on 5th October, which is titled 'Climate Change, Peak Oil, Sex and Death'.  I need to make a Linux equivalent of a 'powerpoint' and I'm not too sure how to do it....

In the evening I visited Helen and Phil round the corner to talk them through using the apple press which has found it's way from Brunswick Organic Nursery to its next group who want to use it.  They are getting together with a few friends and want to make cider.
