Cosmic Variance

Sean

Sean Carroll

Sean Carroll is a Senior Research Associate in the Department of Physics at the California Institute of Technology. His research interests include theoretical aspects of cosmology, field theory, and gravitation. He is the author of a graduate-level textbook, Spacetime and Geometry: An Introduction to General Relativity, as well as a set of Teaching Company lectures on dark matter and dark energy. His new book, From Eternity to Here: The Quest for the Ultimate Theory of Time, explores the relationship between entropy, cosmology, and the arrow of time.

Here are some of his favorite blog posts.

    • Cosmic Variance Cosmic Variance is a group blog by people who, coincidentally or not, all happen to be physicists and astrophysicists:
      • Daniel Holz
      • JoAnne Hewett
      • John Conway
      • Julianne Dalcanton
      • Mark Trodden
      • Risa Wechsler
      • Sean Carroll
      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.
