Science of small particles

There's not much news today, so forgive this very short extract from an otherwise irrelevant (but truly fascinating) article on the science and technology of small particles: "There is even a connection between the Sphinx of Egypt’s Giza plateau and porosity. The Sphinx may be coerced into revealing its true age thanks to the porosity of the stone from which it is made. A model of the weathering process based on the porosity of the stone has been suggested that may yield a timeline back to the date of its creation."
For anyone interested in the whole age of the sphinx debate, Colin Reader has an excellent summary at:
