Lawrence Krauss has a talent for writing a survey that makes a lot of stuff easier to understand. He's a world-class cosmologist and physicist too, as well as talented writer. There was a conference/workshop of NEUTRINO EXPERIMENTALISTS in Venice and they invited Krauss to give a relaxed overview of the big picture of how neutrinos fit into COSMOLOGY. Since neutrino experimentalists are not cosmologists, his talk has to communicate across fields and be very basic. I found it remarkably informative and intuitive---also just 10 pages. Like to share this in case anyone's interested: http://arxiv.org/astro-ph/0605378 WHAT IS THE ROLE OF NEUTRINOS IN SHAPING THE UNIVERSE?
