We had an education talk yesterday afternoon, because today’s colloquium speaker, Ann Martin from Cornell, has strong interests in that and wanted to talk to people about it. A lot of the discussion had to do with teaching students to write, and getting them to accept feedback. Martin spoke very positively of a writing-intensive introductory… Continue reading What Grade Do You think You’re Getting?

Quantum Mechanics vs. Relativity: It Depends on What “Understand” Means
Sean Carroll and Brad DeLong have each recently asserted that relativity is easier to understand than quantum mechanics. Both quote Feynman saying that nobody understands quantum mechanics, but Sean gives more detail: “Hardness” is not a property that inheres in a theory itself; it’s a statement about the relationship between the theory and the human… Continue reading Quantum Mechanics vs. Relativity: It Depends on What “Understand” Means
Physics Takes Practice
Doug Natelson talks about a recent presentation on education: I recently heard a talk where a well reputed science educator (not naming names) argued that those of us teaching undergraduates need to adapt to the learning habits of “millennials”. That is, these are a group of people who have literally grown up with google (a… Continue reading Physics Takes Practice
Next Weekend at AAAS
As I’ve mentioned in passing before, I’ll be attending the Annual Meeting of the American Association for the Advancement of Science next weekend, in order to appear on a panel about the TIMSS Advanced 2008 test. I’m an idiot, and didn’t submit an abstract in time (I thought there was a perfectly adequate placeholder abstract… Continue reading Next Weekend at AAAS
Notes Toward “A Brief History of Timekeeping”: Kooks and Sticks
Barring a major disaster, I am scheduled to teach one of our Scholars Research Seminar classes next winter. I’ve been kicking the idea for this around for a while, with the semi-clever title “A Brief History of Timekeeping.” The idea is to talk about the different technologies people have used to mark the passage of… Continue reading Notes Toward “A Brief History of Timekeeping”: Kooks and Sticks
Talking Dogs Are Big in Italy
I haven’t been as relentless about flogging How to Teach Physics to Your Dog (now available in paperback!) as I was last year, because it gets kind of exhausting. I do have a vanity search set up on Google Reader that points me to the occasional review– this one, for example, so I still see… Continue reading Talking Dogs Are Big in Italy
Academic Poll: Refereeing Ethics
The “peer reviewers get worse” item in this morning’s Links Dump drew an immediate comment elsewhere to the effect of “of course they do, because they start pawning reviews off on their students. This one was a surprise to me, so here’s a quick poll to see if my subfield of physics is really that… Continue reading Academic Poll: Refereeing Ethics
Heavy Heavy Water
I make an effort to say nice things about pop-science books that I read, whether for book research or blog reviews. Every now and then, though, I hit a book that has enough problems that I have a hard time taking anything positive from it. I got David Bodanis’s E=mc2: A Biography of the World’s… Continue reading Heavy Heavy Water
Energy from Mass, Mass from Energy
I probably ought to get a start on the big pile of grading I have waiting for me, but I just finished a draft of the problematic Chapter 7, on E=mc2, so I’m going to celebrate a little by blogging about that. One thing that caught my eye in the not-entirely-successful chapter on momentum and… Continue reading Energy from Mass, Mass from Energy
It’s About Time by David Mermin
Subtitled “Understanding Einstein’s Relativity,” David Mermin’s It’s About Time is another book (like An Illustrated Guide to Relativity) that grew out of a non-majors course on physics that Mermin offers at Cornell. It’s also an almost-forty-years-later update of an earlier book he wrote on the same subject. And it’s been a really good resource for… Continue reading It’s About Time by David Mermin
