My career in science started with a degree in Natural Science at the University of Cambridge specialising in quantum chemistry. Then I did a PhD, also at Cambridge, in solid state photochemistry. To my surprise as indeed are , even though the World Wide Web didn`t exist at the time! After finishing my PhD I worked as a colloid scientist for . Now I`m getting old and grey I answer questions on the Physics Stack Exchange to stop my brain from atrophying. I`m mostly interested in general relativity though I`ll have a go at anything related to quantum mechanics as well. Next on my bucket list is to learn quantum field theory though that is turning out to be a challenge! I hang around and I`m happy to answer questions there as well. Just ping me if you want my attention. ©
