“Talking Dogs and Galileian Blogs: Social Media for Communicating Science”

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… Continue reading “Talking Dogs and Galileian Blogs: Social Media for Communicating Science”

“Talking Dogs and Galileian Blogs” at Vanderbilt, Thursday 3/26/15

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… Continue reading “Talking Dogs and Galileian Blogs” at Vanderbilt, Thursday 3/26/15

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… Continue reading How Does Angular Momentum Emerge?

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… Continue reading The Emergence of Angular Momentum

Just How Idiotic Are GPAs?

Comparison of "GPA" for simulated B students with and without the intermediate step of passing through letter grades.

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… Continue reading Just How Idiotic Are GPAs?

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… Continue reading GPA’s Are Idiotic

Upcoming Talks: New Paltz Tonight, Nashville Next Week

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… Continue reading Upcoming Talks: New Paltz Tonight, Nashville Next Week

STEM Gender Gaps and Draft Dodging

Mike Mastroianni '07 speaking at the Physics and Astronomy Colloquium last week.

It’s always a pleasure to see former students doing well, and to that end, we invited one of my former thesis students, Mike Mastroianni, class of 2007, to give a colloquium talk last week in the department. Mike went to physics grad school for a couple of years after graduation, but decided he was more… Continue reading STEM Gender Gaps and Draft Dodging

The Two-Box Addition Game

Scratch paper from figuring out the two-number addition game.

SteelyKid’s school does a “March Math Madness” thing, and this year all the kids in her class are being asked to practice “Math Facts” for ten minutes a night. This appears to be motivated by some requirement that students be able to rattle off basic addition problems at high speed. So there are flash cards… Continue reading The Two-Box Addition Game

Announcing the Schrödinger Sessions: Science for Science Fiction

A few years back, I became aware of Mike Brotherton’s Launch Pad Astronomy Workshop, and said “somebody should do this for quantum physics.” At the time, I wasn’t in a position to do that, but in the interim, the APS Outreach program launched the Public Outreach and Informing the Public Grant program, providing smallish grants… Continue reading Announcing the Schrödinger Sessions: Science for Science Fiction
