Most of what would ordinarily be blogging time this morning got used up writing a response to a question at the Physics Stack Exchange. But having put all that effort in over there, I might as well put it to use here, too… The question comes from a person who did a poster on terminology […]

Poll: Top Physics Story of 2010?
It’s the last week of the (calendar) year, which means it’s a good time to recap the previous twelve months worth of scientific news. Typically, publications like Physics World will publish a list of top ten physics stories of 2010, but we’re all Web 2.0 these days, so it seems more appropriate to put this […]
How Does Light Travel Through Glass?
I’ve mentioned before that I’m answering the occasional question over at the Physics Stack Exchange site, a crowd-sourced physics Q&A. When I’m particularly pleased with a question and answer, I’ll be promoting them over here like, well, now. Yesterday, somebody posted this question: Consider a single photon (λ=532 nm) traveling through a plate of perfect […]
Teleportation of Toddler Toys
Today is the official release date for the paperback edition of How to Teach Physics to Your Dog, so I wanted to write up something cool about quantum physics to mark the occasion. I looked around the house for inspiration, and most of what we have lying around the house is SteelyKid’s toys. Thus, I […]
Interference of Independent Photon Beams: The Pfleegor-Mandel Experiment
Earlier this week, I talked about the technical requirements for taking a picture of an interference pattern from two independent lasers, and mentioned in passing that a 1967 experiment by Pfleegor and Mandel had already shown the interference effect. Their experiment was clever enough to deserve the ResearchBlogging Q&A treatment, though, so here we go: […]
The Unexpected Leaping Ability of Bovines
I’m spending the day trying to get some work done on the book-in-progress, so I’m avoiding both work- and blog-related stuff. I don’t want to leave the site completely quiet, though, so here’s a question to ponder, relating to SteelyKid’s continuing fascination with Goodnight Moon: How does a cow jump over the moon? The father […]
The Calculus Diaries by Jennifer Ouellette
I finished Jennifer Ouellette’s new book a few weeks ago, shortly after my trip to Alabama, but it’s taken me a long time to get around to reviewing it due to a combination of too much work and being a Bad Person. There’s finally a tiny break in the storm of work, though, so here’s […]
Experiment vs. Theory: The Eternal Debate
Melissa at Confused at a Higher Level offers some thoughts on the relative status of experimental vs. theoretical science, spinning off a comprehensive discussion of the issues at Academic Jungle. I flagged this to comment on over the weekend, but then was too busy with SteelyKid and football to get to it. since I’m late […]
The Physics Bus
SteelyKid, like most toddlers, knows a few songs, and likes to sing them over and over. Her repertoire is limited to “ABCDEFG” (the alphabet song, but that’s how she requests it), “Twinkle, Twinkle,” “Some man” (“This Old Man,” which I only figured out this weekend), and “Round and Round” (“The Wheels on the Bus”). I […]
What Every Dog Should Know About Quantum Physics
A quick check-in from Tuscaloosa, where we’re getting ready to head out for the football tailgating. While I’ve got a minute, though, here are the slides from my public lecture, via SlideShare: What Every Dog Should Know About Quantum Physics View more presentations from Chad Orzel. These are probably less comprehensible that some of my […]
