Yesterday’s post on a variation of the “Twin Paradox” with both twins accelerating was very successful– 337 people voted in the first poll question, as of a little before 9am, and the comments to the original post are full of lively discussion. That’s awesome. I wish I could take credit for it, but the problem… Continue reading Accelerated Twins: The Answer

Physics Quiz: Accelerated Twins
Just about everybody has heard of the Twin Paradox in relativity: one twin becomes as astronaut and sets off for Alpha Centauri, the other remains on Earth at mission control. Thanks to time dilation, the two age at different rates, and the one who made the trip out and back ends up younger than the… Continue reading Physics Quiz: Accelerated Twins

Laser Smackdown: Amazing Laser Applications
Last week, I asked for nominations of the most amazing laser application, with the idea being that I will collect a list, write up the top vote-getters in a series of blog posts, and then we will have a vote to determine what is THE coolest laser application of ALL TIME! At least, you know,… Continue reading Laser Smackdown: Amazing Laser Applications
Upcoming Appearances: How to Teach Physics to Your Dog Live
Two events in the next couple of weeks at which I will be appearing live and in person: 1) This Thursday, Feb. 4, I will be giving a talk at the University of Maryland, College Park at 3:30 pm in the Lecture Hall (room 1110) in the Kim Engineering Building. The title of the talk… Continue reading Upcoming Appearances: How to Teach Physics to Your Dog Live
From Eternity to the Web
The Firedoglake Book Salon with Sean Carroll last night was a lot of fun. I was generally impressed with the level of the questions, and the tone of the discussion. We went through all of the questions I had typed out in advance (I type fairly slowly, and revise obsessively, so it’s hard for me… Continue reading From Eternity to the Web
How to Teach Physics to Your Dog: Obsessive Update
A few bits and pieces of news regarding How to Teach Physics to Your Dog: We got and accepted an offer for the audio book rights from one of the biggest audio book publishers. Actually, I think there were two offers for the audio rights, which is amazing. I have no idea when it would… Continue reading How to Teach Physics to Your Dog: Obsessive Update
How to Teach Physics to Your Dog: Obsessive Update
Hard to believe it’s been a couple of days since I posted anything with this title… Anyway, there are a couple of small updates: The vanity search turned up this mention on ScienceBase, in with a bunch of other recent science books that sound pretty good. The Union student paper, the Concordiensis, has a story… Continue reading How to Teach Physics to Your Dog: Obsessive Update
Continuity, Discretion, and the Perils of Popularization
Last week’s Seven Essential Elements of Quantum Physics post sparked a fair bit of discussion, though most of it was at the expert level, well above the level of the intended audience. such is life in the physics blogosphere. I think it’s worth a little time to unpack some of the disagreement, though, as it… Continue reading Continuity, Discretion, and the Perils of Popularization
Quantization of Books 4: How Many Books Is That Again?
I’ve toyed around in the past with ways to use the Amazon sales rank tracker to estimate the sales numbers for How to Teach Physics to Your Dog. It’s geeky fun, but not especially quantitative. Yesterday, though, I found a reason to re-visit the topic: calibration data!
