Marcus Wilson Oct 18, 2019

In the last couple of weeks, I’ve been busy preparing for our summer paper on Science Communication. Looking for something amusing about ‘risk’ in science, I came across this neat xkcd.com cartoon about why so many people come knocking on my door (or phoning me, or emailing me) desperately wanting me to spend hundreds of thousands of dollars proving … Read More

Alice the camel had four humps… Alice … Read More
