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:…

I hinted once or twice that I had news coming, and this is it: I’ve signed up to be a blog contributor at Forbes writing about, well, the sorts of things I usually write about. I’m pretty excited about the chance to connect with a new audience; the fact that they’re paying me doesn’t hurt,…

That’s the title of the talk I gave yesterday at Vanderbilt, and here are the slides: Talking Dogs and Galileian Blogs: Social Media for Communicating Science from Chad Orzel The central idea is the same as in past versions of the talk– stealing Robert Krulwich’s joke contrasting the publication styles of Newton and Galileo to…

I mentioned last week that I’m giving a talk at Vanderbilt tomorrow, but as they went to the trouble of writing a press release, the least I can do is share it: It’s clear that this year’s Forman lecturer at Vanderbilt University, Chad Orzel, will talk about physics to almost anyone. After all, two of…

How Does Angular Momentum Emerge?

Yesterday’s post about VPython simulation of the famous bicycle wheel demo showed that you can get the precession and nutation from a simulation that only includes forces. But this is still kind of mysterious, from the standpoint of basic physics intuition. Specifically, it’s sort of hard to see how any of this produces a force…

The Emergence of Angular Momentum

The third of the great physics principles introduced in our introductory mechanics courses is the conservation of angular momentum, or the Angular Momentum Principle in the language of the Matter and Interactions curriculum we use. This tends to be one of the hardest topics to introduce, in no small part because it’s the last thing…

Favorite Quantum Physics in Fiction?

We’ll be accepting applications for The Schrödinger Sessions workshop at JQI through tomorrow. We already have 80-plus applicants for fewer than 20 planned spots, including a couple of authors I really, really like and some folks who have won awards, etc., so we’re going to have our work cut out for us picking the attendees……

Just How Idiotic Are GPAs?

Yesterday’s quick rant had the slightly clickbait-y title “GPAs are Idiotic,” because, well, I’m trying to get people to read the blog, y’know. It’s a little hyperbolic, though, and wasn’t founded in anything but a vague intuition that the crude digitization step involved in going from numerical course averages to letter grades then back to…

GPA’s Are Idiotic

I was thinking about something only tangentially related to grading, when it struck me that the way we go about generating student grade point averages is the kind of mind-bogglingly stupid system that requires lots of smart people working together to produce. Two very different groups of smart people, with very different ways of looking…

I keep forgetting to mention these, but I have two talks coming up: 1) Tonight, March 17, I’m talking about Eureka to the Mid-Hudson Astronomical Association on the campus of SUNY New Paltz. This is a version of the talk I gave in Bristol, UK over the summer, but with the soccer content replaced with…
