This is the headquarters for "A User's Guide to the Universe," published in March 2010, and "The Universe in the Rearview Mirror" published in Summer, 2013. We've got fun cartoons, snarky commentary on cosmology and physics, and tutorials on everything from black holes to the Higgs Boson.

Ask a Physicist is back, baby!
After an unacceptably long hiatus, I’m back with new “Ask a Physicist” columns over at io9. Today, I have a piece up about PeV neutrinos, and tomorrow I’ll be doing one on Emmy Noether. Thereafter, I’ll be posting a bit … Continue reading
What should a physics major know?
It’s summer. In academia, it’s a time to get some real research done, take a little R&R with ones family, perhaps wait in breathless anticipation of the paperback release of ones book, and most relevant to today’s discussion, to think … Continue reading
Best. Class. Ever.

Does it make sense?
A question from a reader: My dad always told me, after finishing a math problem for homework, ‘look at the answer and ask your self ‘does this answer make sense’” So, my question is: do the answers we get from … Continue reading
A Technical Post – On more than 3 dimensions
I’ve made the occasional passing comment about how fortunate we are to live in a 3-dimensional universe. In an old ““Ask a Physicist” column (in a precursor to a fairly important discussion in my new book) I dropped a little … Continue reading
I get mail: Dark Energy, The Expanding Universe, and Noether’s Theorem
You know I love getting mail. I like getting questions, brain-teasers, compliments, or in rare cases, all three. Not every question is right for my “Ask a Physicist” column over at io9, either because it’s a bit too specific or … Continue reading
Blastoff!
Good news, everyone! I was on the Professor Blastoff Podcast this week talking about “The Universe” (which may win the prize for best episode name) with Tig, David and Kyle. We talk about time travel, symmetry, antimatter (and Uncley matter, … Continue reading
Higgs!
Francois Englert and Peter Higgs In a move that surprised almost no one in the physics community, the Nobel Prize in Physics was awarded this morning to François Englert and Peter W. Higgs “for the theoretical discovery of a mechanism … Continue reading
