So this is my last day at the festival! The first talk I attended was one that I had been looking forward to called `Vitamin D: The sunshine superstar’. All I knew on the subject was that sunlight was needed for vitamin D synthesis, and I wondered being from Scotland, if I might be deficient!

Today started with a lecture on “What Computers Tell Us About the Mind”. One speaker from the University of Glasgow presented his research on face recognition. He made the interesting point that we experience no difficulty recognising faces we have seen before, but when it comes to unfamiliar faces we find it much harder.

Day two began with a tour of the universe, again with Dr Maggie. I should mention that she has been awarded an MBE by the Queen but – I’m sure you will agree – the fact she has a Blue Peter badge is much more impressive! Her talk involved building a rocket from baking powder and vinegar, a great Blue Peter make!

The British Science Festival 2009 begins! It promises everything from Darwin to dishonesty labs, microscopes to memory, covering everything from the microscopic virus to the entire milky way.
