If you want to see your shadow dissappear then keeping looking at your feet on Thursday 27 August 2009. Just watch out for lamposts!


Excerpt from 'Space News' - Dr. Shirin Haque, Astronomer, University of the West Indies.
' On Thursday August 27, the sun will be directly overhead in Trinidad at 12.07 pm. It is interesting to watch your shadow disappear underneath you - Look out Peter Pan!
An Astronomer colleague of mine from Finland was photographing shadows enthusiastically in Trinidad when he visited and quipped he had never seen such short shadows! In Finland at 60 degrees North latitude, shadows are always much longer. The sun never passes directly overhead anywhere in the world North or South of 23.5 degrees latitude.
You may take your shadows for granted, but it was noticing and measuring the different lengths of shadows at different places that the Mathematician and librarian at Alexandria Eratosthenes calculated the circumference of the Earth to impressive accuracy over 2000 years ago !
Indeed they knew from the different lengths of the shadow at the same time in different places that the world was round , thousands of years before the claim of the ‘discovery’ that the world is round from Christopher Columbus.'
