On the Checking of Boxes, and the Need to Chill Out

In the comments to yesterday’s post about college admissions, Joseph Yoon quoted my statement that “I’m somewhat sympathetic to claims that Asians have a difficult position in higher education,” and shot back with: I wonder if you will feel more strongly about this in 10 years when your kids are near college. Will you advise… Continue reading On the Checking of Boxes, and the Need to Chill Out

The Visual Presentation of Misleading Information, Anti-Asian Bias Edition

A badly done graph showing enrollment trends at Ivy League schools plus Caltech.

In which the skewing of a data plot in Ron Unz’s epic investigation of college admissions makes me more skeptical of his overall claim, thanks to the misleading tricks employed. ———— Steve Hsu has a new post on a favorite topic of his, bias against Asians in higher ed admissions. This is based on a… Continue reading The Visual Presentation of Misleading Information, Anti-Asian Bias Edition

Using Light to Put a Mirror in the Dark: “Optomechanical Dark Mode”

A laser (red arrow) exciting an atom. On the left, an atom with only two levels must return to the same initial state; on the right, the atom can decay into a superposition of two states.

In which I unpack a cryptic paper title and explain how quantum superposition lets you use light to keep things from interacting with light. ————- I joined AAAS a couple of years ago to get a break on the registration fee for their meeting, and I’ve kept up the membership mostly because I like having… Continue reading Using Light to Put a Mirror in the Dark: “Optomechanical Dark Mode”

The Inspiring Power of You’re Doing It Wrong

I’ve got a bunch of browser tabs open on my various computers that have been there for weeks, one of which is Alastair Reynolds on writing science fiction. This is mostly a response to a not-terribly-interesting complaint that the science fiction genre has been “exhausted,” but there was a bit in there that resonated with… Continue reading The Inspiring Power of You’re Doing It Wrong

Hobbits and Prime Ministers: The Physics of Doors

Peter Jackson in the door to Bag End.

Over at Tor.com, Kate has begun a chapter-by-chapter re-read of The Hobbit, and has some thoughts on Chapter 1. It’s full of interesting commentary about characters and literary technique, but let’s get right to the important bit: Physics! Kate mentions in passing in the post that the Hobbit style round door with a knob in… Continue reading Hobbits and Prime Ministers: The Physics of Doors

Why Are Physics Classes Full of Old Stuff?

Minute Physics's open letter to the President.

Everybody and their siblings have been linking to this Minute Physics video, an “open letter” to President Obama complaining about the way that most high school and even intro college physics classes don’t teach anything remotely modern: I’m not entirely sure where the date of 1865 comes from, but it’s true, the standard intro physics… Continue reading Why Are Physics Classes Full of Old Stuff?

Do the New Paper Dance

OK, it’s a paper I mentioned here before, when it went up on the arxiv, but the “Comments on Atomic, Molecular, and Optical Physics” article I wrote this summer is up on the Physica Scripta web site now, and for the next not-quite-thirty days it’s free to read and download: Searching for new physics through… Continue reading Do the New Paper Dance

Financiers Still Aren’t Rocket Scientists

Over at Slate, John Dickerson has a piece expressing amazement that “numbers guy” Mitt Romney was so badly misinformed about the election. While I’ll admit to a certain amount of schadenfreude about the general bafflement of the Romney campaign and the Republicans generally, this particular slant (which Dickerson isn’t the only one to take, just… Continue reading Financiers Still Aren’t Rocket Scientists

Twilight of the Elites and the Rise of the Culture

In which I use my double license as a physicist and a science fiction fan to engage in some half-assed futurism spinning off Chris Hayes’s much-discussed book. ————- I don’t read a lot of political books, because I tend to find them frustrating. They’re usually surprisingly ephemeral, trying to spin Deep Meaning out of a… Continue reading Twilight of the Elites and the Rise of the Culture

What’s FiveThirtyEight Good For?: The Inevitable Nate Silver Backlash

Relative collision rates for different isotopes of metastable xenon. Figure from my Ph.D. thesis.

Now that we’ve apparently elected Nate Silver the President of Science, this is some predictable grumbling about whether he’s been overhyped. If you’ve somehow missed the whole thing, Jennifer Ouellette offers an excellent summary of the FiveThirtyEight saga, with lots of links, but the Inigo Montoya summing up is that Silver runs a blog predicting… Continue reading What’s FiveThirtyEight Good For?: The Inevitable Nate Silver Backlash
