Interesting and Useful Physics Blogs


Some scientists and commentators have begun writing physics blogs to spread the word about latest discoveries and research in science. The list below includes some of the top physics blogs, which regularly provide some of the most interesting and useful content on the status of physics. Some of the physics blogs focus on narrow topics, such as string theory, while others cast a far wider net. All are illuminating, in their own ways.

About.com Physics Blog

Our very own About.com Physics blog covers topics ranging from breaking physics news to historical information and homework help. It's a wonderful catch-all resource for top information about physics on the internet (if we do say so ourselves).

Cosmic Log

This wonderful news blog covers physical sciences, anthropology, technology innovation, and space science. It is written by MSNBC science editor Alan Boyle.

NOVA Physics: The Nature of Reality

In my house, we love the NOVA science series on PBS. Turns out that they have a blog, as well, called "The Nature of Reality," which features some very interesting articles ... including guest posts from prominent physicists on a fairly regular basis. They even had the good taste to commission a guest post from a certain handsome physics writer that I know. (Disclaimer: I'm talking about myself.)

Cosmic Variance

Discover magazine's theoretical physics blog, written by seven or so physicists and astrophysicists, covering recent physics news, research, and discoveries.

Bad Astronomy

This is Discover magazine's astronomy blog, focusing on the space sciences. Sometimes there's overlaps between this and Cosmic Variance, mostly in the realm of cosmology, but since real discoveries in that area are relatively few and far between, a lot of the time this focuses on space missions or good old-fashioned star watching (though the equipment, and images, are anything but old fashioned).


The blog of Clifford V. Johnson, physics professor at the University of Southern California's Department of Physics and Astronomy. As he says, Aymptotia is "a blog written by a scientist" focusing on the topics of "Science, Arts, Academia, Gardening, Environment, Music, Society, Food, Drink, Life, Friends, Fun, Travelling…"

Symmetry Breaking

Symmetry Breaking is the blog of Symmetry magazine, a joint publication of Fermilab and SLAC that covers the latest happenings in particle physics. Though it is the blog of two American institutions, it of course covers physics the world over, since science knows no national boundaries.


This one is the personal blog of two theoretical physicists, so it covers not only theoretical physics but also more general references about their lives. Self described as "A scientifically minded blog with varying amounts of entertainment, distractions, and every day trivialities."

Not Even Wrong

Peter Woit's blog which is skeptical about string theory, frequently presenting the opposing side to recent string theory findings. Woit is a physicist by education, but works as a mathematician these days. His main claim to fame in the realm of physics has been his book Not Even Wrong: The Failure of String Theory and the Search for Unity in Physical Law which is, as the name suggests, highly critical of string theory's claims.

The Reference Frame

Lubos Motl's intense blog, where he rails against string theory skeptics, women in physics, and various other things he finds offensive, often in language that clearly expresses the offense that he feels. Frequently responds (passionately) to Woit's blog.

Cocktail Party Physics

This blog, subtitled "Physics with a Twist," is written by an eclectic assortment of scientists and science writers, about a wide range of physics-related topics. Their one-line bio ("Serving up science and culture with a splash of wit.") is a good description of the material you'll find here. For someone who wants their blog to touch their funny bone as well as their intellect, I recommend Cocktail Party Physics as a good place to visit regularly.

13.7: Cosmos and Culture

13.7: Cosmos and Culture is a new blog from NPR set "at the intersection of science and culture." The writers of the blog include an astrophysicist, a theoretical physicist, a science journalist, and two biologists. At the time of this writing, there is a fascinating debate among the writers about the role of reductionism in science.

The name, 13.7, comes from the fact that the universe is approximately 13.7 billion years old.
