A collection of miscellaneous stuff with an academic inclination from the past week or so: — We gave an exam last night in introductory E&M (I’m teaching one of five sections this term), so we’ve spent a lot of time this week on exam review. One thing that might be worth mentioning here is the… Continue reading Academic Round-up: Exam Review, Student Comments, Speaker Invitations

Food Takes Time
Kevin Drum and Aaron Carroll report on a new study of the effect of new grocery stores opening in “food deserts” in poor neighborhood. The study is paywalled, so I can’t speak to the whole thing, but both of them quote similar bits making the same point: no statistically significant effects on the BMI of… Continue reading Food Takes Time
The Evergreen Topic of Grade Inflation
There was a flurry of re-shares last week for this article about Yale shutting down a site that aggregated student course evaluations, which is fine as far as it goes, but repeats a stat that really bugs me: About 43 percent of college letter grades in 2011 were A’s, up from 31 percent in 1988… Continue reading The Evergreen Topic of Grade Inflation
Congratulations to Fama, Hanson, Schiller, and DougT
It was looking like we were going to slip through the entire Nobel season without a winner in the Uncertain Principles Betting Pool, but at the eleventh hour, we got one: DougT correctly predicted that the 2013 Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel would be shared by Eugene Fama (remember,… Continue reading Congratulations to Fama, Hanson, Schiller, and DougT
Gender Gap Update
The JCC day care is closed today for one of the fall cluster of Jewish holidays, which means I’m spending the morning with The Pip before Kate comes home to take the afternoon shift so I can teach my class. Thus, this is more of a tab clearance sort of exercise than a thoughtful examination… Continue reading Gender Gap Update
White People Only Have 2.8 Friends
There was some buzz Thursday about a poll showing that 40% of white people don’t have any friends of a different race. Ipsos/Reuters include a spiffy “data explorer” where you can make graphs like the one above. It does not appear to provide an easy way to get at the actual wording of the question,… Continue reading White People Only Have 2.8 Friends
Physics Research Survey and Contest
One of my colleagues at Union is doing a physics education research project with a summer student, and is using an online survey to collect data. Obviously, the more people respond to the survey, the more scientific it becomes (subject to the limitations imposed by relying on self-selected Internet samples, of course), so I offered… Continue reading Physics Research Survey and Contest
Baseball and Gender Bias: “Number of Women in Physics Departments: A Simulation Analysis “
I’ve spent a bunch of time recently blogging about baseball statistics, which you might be inclined to write off as some quirk of a sports-obsessed scientist. I was very amused, therefore, to see Inside Higher Ed and ZapperZ writing about a new AIP report on women in physics (PDF) that uses essentially the same sort… Continue reading Baseball and Gender Bias: “Number of Women in Physics Departments: A Simulation Analysis “
Dorky Poll: Rorschach Numbers
It’s been a really long time since I’ve done a Dorky Poll here, but I’m pretty fried at the moment, so here’s a kind of mathematical personality test: two numbers that do not uniquely define a sequence, but suggest some possibilities that reveal your innate character type and/or appropriate career path: Personality Test: What number… Continue reading Dorky Poll: Rorschach Numbers
Science Is Hard?: “A Major in Science? Initial Beliefs and Final Outcomes for College Major and Dropout”
There was a brief flurry of discussion yesterday kicked off by Matt Yglesias posting People Don’t Major in Science—Because It’s Hard, which more or less says what the title would lead you to believe (either title, since he’s blogging for Slate where they like to give pages titles that don’t match the post titles…). This… Continue reading Science Is Hard?: “A Major in Science? Initial Beliefs and Final Outcomes for College Major and Dropout”
