When Your Co-Author Is a Monstrous Ass

Who hasn't worked with a disagreeable person—and in the world of science publishing, authored a paper with one?  That wasn't exactly what went through the mind of William Hoover, a physicist at the Lawrence Livermore National Laboratory, when he included an Italian co-author to his 1987 paper.

This Is What We Don’t Know About The Universe

In recent days I’ve had some interesting conversations. There’s a giddiness going around, related to an outpouring of science love – the kind you get from President Obama introducing TV science shows, the kind that has wonderful visuals, but is, well, a wee bit simplistic (a sin that none of us could ever, ever be [...]
