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
Entry Points and Resource Allocation
Over in locked LiveJournal land, I read a post talking about computer science education, and how it’s biased against people who aren’t already tech geeks coming into college: Taking an intro CS course if you don’t already know how to program is like taking intro Spanish without ever having taken it in high school –… Continue reading Entry Points and Resource Allocation
Dorky Poll: Favorite Prime Number?
A pretty straightforward question: Which prime number do you like the best? What’s your favorite prime number?online surveys This is a purely classical poll, so you only get to choose one favorite, not a superposition of multiple numbers. Your selection is legally binding, so choose wisely!
Academic Poll: Talk Prep
I’m giving a talk at the AAAS meeting next month on international physics tests, and they have asked me to provide information that they will duplicate and distribute to the media. Items requested include: — A one-paragraph biographical sketch (not a C.V.) — A lay-language summary of your talk, beyond the abstract. — The full… Continue reading Academic Poll: Talk Prep
Academic Poll: Appropriate Language
We did a lab yesterday that asked students to measure the speed of a ball leaving a spring-loaded launcher in a few different ways. this is a great way to talk about the difference between systematic and random errors and how those are dealt with. As a way of starting that discussion, I asked the… Continue reading Academic Poll: Appropriate Language
Photons and Atoms Approaching Equilibrium
The latest snowstorm is wreaking some havoc on my plans for the day, which means I’m going to lift another question and answer from the Physics Stack Exchange, with some modification. This one is a question about thermal radiation: What are the quantum mechanisms behind the emission and absorption of thermal radiation at and below… Continue reading Photons and Atoms Approaching Equilibrium
What Counts As Successful Outreach?
Part of this past weekend’s meeting of the Committee on Informing the Public was to evaluate 100+ proposals for “mini-grants” of up to $10,000 for new outreach activities. It wouldn’t be appropriate to go into detail about any of the proposals or what we decided (the PI’s of the proposals we decided to fund will… Continue reading What Counts As Successful Outreach?
Physics Announcements: New Forum, Undergraduate Research Session
I was at a meeting of the Committee on Informing the Public of the American Physical Society at the tail end of last week, so it seems appropriate to post a couple of APS-related announcements here on my return: 1) The APS has just created a Forum on Outreach and Engaging the Public. You may… Continue reading Physics Announcements: New Forum, Undergraduate Research Session
Massive by Ian Sample
The physics book generating the most bloggy buzz in the latter part of 2010 would have to be Ian Sample’s Massive: The Missing Particle that Sparked the Greatest Hunt in Science, about the as yet undetected particle known as the Higgs boson. Detecting the Hiigs is the most immediate goal of the Large Hadron Collider,… Continue reading Massive by Ian Sample
