This is not a science blog. This is a learning blog. Science blogs are written by post-graduates, by researchers and science journalists and I am none of those things. I am a completely average person who just happens to love science, who wants to learn more and who wants to record the journey. There will be no ground-breaking concepts, grandiose proclamations or pretense of advanced knowledge. Please read this blog in the spirit I intend it – one of boundless curiosity.
