Triple J radio in Australia (the government funded "youth" radio station) has a science show with a guy called Dr Karl. http://en.wikipedia.org/wiki/Karl_Kruszelnicki http://en.wikipedia.org/wiki/Karl_Kruszelnicki "He holds degrees in mathematics, biomedical engineering, medicine and surgery. He has also studied astrophysics, computer science and philosophy. He has worked as a physicist, labourer, roadie for bands, car mechanic, film-maker, hospital scientific officer, biomedical engineer, TV weatherman, taxi driver and medical doctor." He also written a ton of books and won an Ig Noble prize for his extensive research in to belly button lint colouring. He is clearly totally awesome. Anyway, petrichor is old news to listeners of his radio show, as it's been discussed there numerous times. I highly recommend listening to his podcast, it's full of all sorts of random sciencey stuff presented in an easy to digest way: http://www.abc.net.au/science/drkarl/scienceontriplej/ http://www.abc.net.au/science/drkarl/scienceontriplej/
