I’m in Dublin as a delegate at something called the Euroscience Open Forum. To me, it is a science festival, but in typical European style, it has a rather strange name. It consists of a series of talks, discussions, debates, workshops, plays, poetry readings and much else besides, covering all areas of science, from my […]

Earth is very big of course. Its circumference is more than 10 million times the height of a human being. The image to […]
