Cosmic Variance

Cosmic Variance is a group blog by five people who, coincidentally or not, all happen to be physicists and astrophysicists: Mark Trodden, Risa Wechsler, Sean Carroll, Clifford Johnson, and JoAnne Hewett. Our day (and night) jobs notwithstanding, the blog is about whatever we find interesting science, to be sure, but also arts, politics, culture, technology, academia, and miscellaneous trivia. We have similar outlooks on many things, widely disparate opinions about others, and will do our best to keep the discourse reasonably elevated.
