I case you hadn’t realised, it’s the Winter Solstice in the Northern Hemisphere today. In fact it’s already happened , at 05.30 UK this morning, so the Sun has already started to processing southwards and the days will start to become imperceptably longer. It is of course the shortest day today … a whole 2 seconds shorter than yesterday.
Hooray ! A tangible cause for celebration at this time of year.
Happy Winter Solstice 2011 !
P.S. It’s reminded me that I wrote my BSc dissertation on the Mathematical Significances of Stonehenge 23 years ago. I might read back through it and blog a summary… watch this space.
