Taking on the spherists. Australian politics continued on its bizarre trajectory this week, with Senator George Brandis (that warrior for the un-oppressed) claiming that those who refuse to give the same credit to the feelpinions (and/or vested interests) of the climate deniers as they do to the peer-reviewed actual evidence of scientists are mediaeval in their outlook!

As a man with a veritable genius for leading with his chin, Brandis can hardly have been surprised when the wits of social media and the letters pages of our few surviving daily newspapers went to town arguing that those who believe the earth to be flat should therefore also be given the same respect as "sphericalists", as one gleeful letter writer called them in the Fairfax press.
