A Physicist Plays Politics: Part III
Hey gang! It’s been a while, so let’s just jump in, shall we? Every now and again (every four years, apparently) the obsessive statistical monster in me lashes out, and I start thinking obsessively about polls. Full disclosure: while I’m … Continue reading
Best. Class. Ever.
Credit: me. A simple 1d simulation of a complex scalar field in an electric field. You’ll find this more instructive after you’ve read the lecture notes. Click on the link if it doesn’t auto play in your browser. This term, … Continue reading
Probability for Students
I’ve had a lot of students over the years, and I’ve realized that even those who’ve taken a probability and statistics class often lack a gut feeling intuition about how to deal with data. I’ve written a (first draft, admittedly) … 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 3dimensional 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
Travel to the end of the Universe
About a week ago, I had a contest on io9 calling for questions about the universe. I got one that seems, on first blush, to be kind of silly, but on further inspection is kind of awesome. Cameron asks: What … Continue reading
I get mail: Does a box of photons have mass?
Lately, my my inbox hath overflowed. Yesterday, I got a thoughtprovoking email from a fellow physics instructor. It’s a good, nonintuitive question about special relativitiy. It’s also got the “technical” tag, so if you’re afraid of a few equations and … Continue reading
Why the F is not equal to ma
Those of you who know me will also know that I’m a big fan of crossword puzzles. Maybe it’s the rotational and reflection symmetry in American style crosswords, but I make a point to do all of the lateweek puzzles. … Continue reading
Antworld, the Equivalence Principle, and GR
I’ve been thinking a lot about Special and General Relativity lately, and in particular, the Equivalence Principle — the main theme for Chapter 7 of my upcoming book on symmetry. In the process, I started playing around with a really … Continue reading
I get mail: Twin Paradox Edition
Greetings, true believers! Apologies for the relative infrequency in posting, but as most of you know, I’ve been working hard on my upcoming book. I’m over the hump, and sent the first half to my editor a couple of weeks … Continue reading
Reverend Bayes helps us understand the Higgs
I was listening to Tim Harford’s More or Less podcast last week in the wake of all of the excitement over the possible detection of the Higgs boson. More or Less is a show all about statistical abuses in the … Continue reading
