A Constructive Response to Professorial Anxiety

Engaging in a bit of tab clearance before I head off to DAMOP tomorrow afternoon, I noticed that I still had How to Teach an Ancient Rape Joke open. This is because while I found it kind of fascinating, it’s not all that directly relevant to what I do, and I didn’t have anything all… Continue reading A Constructive Response to Professorial Anxiety

What a Difference a Year Makes

SteelyKid dressed in "fancy clothes" (a dress over tights with a picture of stars and nebulae on them), and The Pip in his new Superman shirt.

Back in October or so, SteelyKid’s first-grade class started a weekly journaling exercise. Every Monday, we were supposed to send in a sheet with some prompts on it– words about something interesting that happened over the weekend, and the kids started the day writing about… whatever it was. I was a little dubious about having… Continue reading What a Difference a Year Makes

Crude Monte Carlo Simulation of Light-Bulb Physics

Results of the crude Monte Carlo simulation in the text.

Last week, I did a post for Forbes on the surprisingly complicated physics of a light bulb. Incandescent light bulbs produce a spectrum that’s basically blackbody radiation, but if you think about it, that’s kind of amazing given that the atoms making up the filament have quantized states, and can absorb and emit only discrete… Continue reading Crude Monte Carlo Simulation of Light-Bulb Physics

Breaking Boards

One of the highlights of teaching introductory mechanics is always the “karate board” lab, which I start off by punching through a wooden board. That gets the class’s attention, and then we have them hang weights on boards and measure the deflection in response to a known force. This confirms that the board behaves like… Continue reading Breaking Boards

Toy Roller Coasters and the Energy Principle

A car going around the loop of our toy roller coaster demo.

One of the points I make repeatedly in teaching introductory mechanics (as I’m doing this term) is that absolutely every problem students encounter can, in principle, be solved using just Newton’s Laws or, in the terminology used by Matter and Interactions, the Momentum Principle. You don’t strictly need any of the other stuff we talk… Continue reading Toy Roller Coasters and the Energy Principle

Miscellaneous Academic Job Market Notes

A few things about the academic job market have caught my eye recently, but don’t really add up to a big coherent argument. I’ll note them here, though, to marginally increase the chance that I’ll be able to find them later. — First, this piece at the Guardian got a lot of play, thanks in… Continue reading Miscellaneous Academic Job Market Notes

SteelyKid and the Makey Makey

A couple of weeks ago, after one of my Forbes posts, I got contacted by a publicist working for Makey Makey. They really wanted publicity in Forbes, but that’s above my pay grade; I did, however, say that it sounded like the sort of thing my kids would get a kick out of, and I… Continue reading SteelyKid and the Makey Makey

Why Small Colleges Are Great For Science Students

We’re into admitted student season, that muddy period when large numbers of anxious high-school seniors visit college campuses all over the nation, often with parents in tow, trying to decide where to spend the next four years. As a result, I’ll be spending a good deal of time over the next few weeks talking to… Continue reading Why Small Colleges Are Great For Science Students

Course Report: Brief History of Timekeeping

Student projects from my SRS (L to R): Measuring the flow of powdered eggshell in a "sand timer," a homemade water wheel clock, and a pendulum to measure the effect of thermal expansion.

A few years ago, I taught one of our “SRS” classes, which are supposed to introduce students to research at the college level– I blogged about it while the course was in progress. I taught it again in the recently-concluded Winter term, but didn’t blog much about it because I was mostly doing the same… Continue reading Course Report: Brief History of Timekeeping

STEM Is Not an Alien Menace

Everybody and their extended families has been sharing around the Fareed Zakaria piece on liberal education. This, as you might imagine, is relevant to my interests. So I wrote up a response over at Forbes. The basic argument of the response is the same thing I’ve been relentlessly flogging around here for a few years:… Continue reading STEM Is Not an Alien Menace
