My Gen Ed relativity course has mostly been me lecturing about stuff to this point, so on Wednesday I decided to shake things up a bit and convert a chapter of David Mermin’s It’s About Time. The idea was to get students up and moving around a bit, and actually making some measurements of stuff.… Continue reading Trains of Clocks
On Putting Words in Einstein’s Mouth
Modern media being what it is, I should get out in front of this, so: I am guilty of putting words in Einstein’s mouth. I mean, go watch my TED-Ed video on particles and waves, or just look at the image up top– that very clearly shows Einstein saying words that he probably never said.… Continue reading On Putting Words in Einstein’s Mouth
The Edge of the Sky by Roberto Trotta
I get a fair number of books to review, but I’m often pretty bad about writing them up in a timely manner. Of course, most of them are well over 70 pages long, which is why I’ve managed to turn around Roberto Trotta’s The Edge of the Sky: All You Need to Know About the… Continue reading The Edge of the Sky by Roberto Trotta
Entrance Music
The AV Club had a Q&A last week asking “What would be your entrance music?” As a music fan and a sports junkie this is, of course, a nearly irresistable question, though a lot of other things got in the way before I could get around to typing up an answer. I’ve always kind of… Continue reading Entrance Music
The Pleasure of Working Things Through
My bedtime reading for the past week or so has been Steven Gould’s Exo (excerpt at Tor). This is the fourth book in the Jumper series (not counting the movie tie-in novel), and ordinarily wouldn’t be worth much of a review, because if you haven’t read the first three, this book won’t make a lick… Continue reading The Pleasure of Working Things Through
Uncertain Dots 22
After a long absence due to travel (some of which is discussed), Uncertain dots returns! Rhett and I talk about recent travels, how people going into internet-based physics outreach these days would probably do better to make videos than blog, physics in science fiction, celestial navigation, and as always, our current courses. Some links: —… Continue reading Uncertain Dots 22
Cash and Respect
The London School of Economics has a report on a study of academic refereeing (PDF) that looked at the effect of incentives on referee behavior. They found that both a “social incentive” (posting the time a given referee took to turn around the papers they reviewed on a web site) and a cash incentive ($100… Continue reading Cash and Respect
Bad Graphics, STEM Diversity Edition
There was a article in Scientific American about diversity in STEM collecting together the best demographic data available about the science and engineering workforce. It’s a useful collection of references, and comes with some very pretty graphics, particularly this one, showing the demographic breakdown of the US population compared to the science and engineering fields:… Continue reading Bad Graphics, STEM Diversity Edition
TED-Ed Lesson: What Is the Heisenberg Uncertainty Principle?
The second one of the TED-Ed lessons I wrote about quantum physics has now been published: What Is the Heisenberg Uncertainty Principle. This is, again, very similar to stuff I’ve written before, specifically this old blog post and the relevant chapter of How to Teach [Quantum] Physics to Your Dog. As usual, I tried but… Continue reading TED-Ed Lesson: What Is the Heisenberg Uncertainty Principle?
TED-Ed Lesson: The Central Mystery of Quantum Physics
My TED@NYC adventure last fall didn’t turn into an invite to the big TED meeting, but it did lead to a cool opportunity that is another of the very cool developments I’ve been teasing for a while now: I’ve written some scripts for lessons to be posted with TED-Ed. The first of these, on particle-wave… Continue reading TED-Ed Lesson: The Central Mystery of Quantum Physics
