The release of Expelled has generated all sorts of chatter, almost certainly more than it deserves on its merits as a film. It’s also produced repeated mentions of the fact that it’s the eight highest-grossing political documentary of all time– most recently, Tara Smith writing at Correlations. That claim reminds me of a long-ago student… Continue reading Non-Dorky Poll: Political Documentaries

Stability and Pedagogy
(Because nothing brings in readers like a physics pedagogy post…) Out in Minnesota, Arjendu is expressing high-level confusion about the business of lecturing: As I’ve said a few times before in this blog, I prefer to let students read the text to get a preliminary take on physics content on their own, generate questions and… Continue reading Stability and Pedagogy
Dorky Poll: Calculators
Over at Cosmic Variance, Julianne waxes rhapsodic about her calculator, a HP-15C. This is such an obvious Dorky Poll topic that I can’t believe I didn’t think of it earlier: What sort of calculator do you use? My students, particularly the future engineers, are always shocked by my answer:
Neil Lewis of the New York Times
The much-promised peer-reviewed research post is going to slip by another day, becuase I had forgotten about a talk by Neil Lewis last night on campus. Lewis is an alumnus of Union, and a writer for the Times best known for writing about the prison camps at Guantanamo Bay, Cuba, and he was speaking as… Continue reading Neil Lewis of the New York Times
Political Indoctrination by Faculty
An ad-lib from yesterday’s lecture about interactions between electric fields and neutral matter, paraphrased: So, we can divide macroscopic objects into two categories, based on what happens when you bring large numbers of atoms together. In materials that are insulators, the electrons aren’t free to move. The atoms hold onto their electrons very tightly. They’re… Continue reading Political Indoctrination by Faculty
The Sticky Tape Lab
I had the first lab of the term yesterday in my introductory E&M class. This is the first time I’ve taught out of this book (Matter & Interactions by Chabay and Sherwood), which actually includes the basic elements of this lab as suggested activities in the second chapter of the text. The lab was more… Continue reading The Sticky Tape Lab
Science in the 21st Century
The Perimeter Institute will be hosting a workshop in September on “Science in the 21st Century“: Times are changing. In the earlier days, we used to go to the library, today we search and archive our papers online. We have collaborations per email, hold telephone seminars, organize virtual networks, write blogs, and make our seminars… Continue reading Science in the 21st Century
Social Class and Educational Access
Via Matt Yglesias, the Quick and the Ed offers an absolutely terrific article about the effect of class on access to college, using AJ Soprano as an example. On The Sopranos, AJ was a delinquent, who nevertheless got sent off to college because of the tireless efforts of his mother, and the family’s money. Drawing… Continue reading Social Class and Educational Access
Better Teachers Cost Money
Kevin Drum points to a report comparing international education systems from McKinsey and Company management consultants. The report (9.5 MB PDF) does double duty: it serves as a useful and important contribution to the study of education reform, and also as a case study in how to use PowerPoint to generate documents that are well… Continue reading Better Teachers Cost Money
Dorky Poll: SI or CGS?
I have a doctor’s appointment this morning, and then class, so here’s another Dorky Poll inspired by the fact that I’m teaching intro E&M: What system of units do you prefer for E&M: SI, or CGS? This is even dorkier than usual, so I suppose I should provide some context…
