SteelyKid has had a bit of a sore throat the last few days, which has led to a bit of screaming and crying. Those have been interspersed with her usual cute-toddler behavior, and we managed to squeeze in the traditional Baby Blogging photo: “Why is she waving around a Triscuit box?” you ask. Because she […]

Why I Hate Windows Update, Aleph-nought in a Series
Relevant to yesterday’s discussion, I let Windows install its critical updates on my work computer last night. So far this morning, I have: 1) Spent five minutes looking at the blue Vista start-up screen, as the computer was hung up– not a screen with a “Configuring updates” message, mind– an otherwise blank blue screen with […]
Amazing Laser Application 3: Lunar Laser Ranging!
What’s the application? Measuring the distance from the Earth to the Moon by bouncing a laser off one of the retro-reflector arrays left there by the Apollo missions. What problem(s) is it the solution to? 1) “How does the distance from the Earth to the Moon vary over time due to things like tidal drag?” […]

Cocktail Party Physics: a few choice words from the red pen brigade “The hardest thing about teaching anybody anything is finding the right level of communication, and the right way to express the concepts. It would seem logical that you don’t go all jargony on a rank beginner, anymore than you have to spend time […]
It’s Not Just the Length, It’s the Content
The never-ending discussion of whether the Web can or should replace books has shifted into the corners of blogdom that I follow again, with Kevin Drum arguing for more books, Henry Farrell arguing for shorter books, and Jim Henley agreeing with Henry, and expanding it to fiction. They’re all at least partly right– more shorter […]
Amazing Laser Application 2: Laser Cooling!
What’s the application? Using lasers to reduce the speed of a sample of atoms, thereby reducing their temperature to a tiny fraction of a degree above absolute zero. What problem(s) is it the solution to? 1) “How can I make this sample of atoms move slowly enough to measure their properties very accurately?” 2) “How […]
The Computer Industry Is Making Us Crazy
We had a meeting yesterday with the chair of the CS department, who wanted to know about our computing needs. Sadly, she just meant that she wanted to know what computing things we would like our students to be taught, because my real computing need, as I said to Kate last night, is “I need […]

News: Anything But Studying – Inside Higher Ed “Students’ relatively small dedication of time to out-of-class studying has remained about the same since the survey was first conducted in 2003. In 2008, students in the physical sciences and engineering averaged 15.1 hours each week on out-of-class academic work; while students in the biological sciences reported […]
Radio DogPhysics: Northern Great Plains Edition
Just a reminder, I will be on KSOO radio Tuesday evening, 6:30 pm ET, if you’d like to hear about How to Teach Physics to Your Dog on the radio at the end of an extremely long day. If you’re in broadcast range of Sioux Falls, SD, tune it in, or you can listen live […]
Non-Dorky Poll: Time to Rise and Shine
No substantive blogging for you today, as my alarm clock decided not to go off, causing me to oversleep by the hour that I usually spend on bloggy things. So that you’re not left without blog-related entertainment, though, here’s an appropriate poll topic: How early do you have to set your alarm to get to […]
