The conference I’m at this week is the annual meeting of the Division of Atomic, Molecular, and Optical Physics of the American Physical Society (which this year is joint with the Canadian version, the Division of Atomic and Molecular Physics and Photon Interactions, or “DAMPΦ.” The Greek letter is a recent addition– as recently as… Continue reading Anatomy of a Conference: DAMOP Day 1

Evil Squirrels from Extra Dimensions
It’s been a very long day, so I’m lying on the couch watching “Pardon the Interruption” on ESPN. They’re having a boring conversation about baseball, and I’m just drifting off into a pleasant doze when: “Fear! Fire! Foes! Awake! Fear! Fire! Foes! Awake!“ I jolt awake. “What are you barking at?!?” I yell at the… Continue reading Evil Squirrels from Extra Dimensions
Why Do We Have Stuff? Hints from Fermilab
There’s a Dennis Overbye article in the Times today with the Web headline “From Fermilab, a New Clue to Explain Human Existence?” which I like to think of as a back-handed tribute to the person who linked to an interview with Sean Carroll by calling him “The cosmologist, not the scientist.” This is the secret… Continue reading Why Do We Have Stuff? Hints from Fermilab
Why I’d Never Make It as a Mathematician
Matt’s Sunday Function this week is a weird one, a series that is only conditionally convergent: So the sum of the infinite series, by inexorable logic, is both ln(2) and ln(2)/2. How is this possible? Of course it isn’t. The flaw in our logic is the assumption that the series has a definite sum –… Continue reading Why I’d Never Make It as a Mathematician
Quick Impressions of Bohmian Mechanics
I get asked my opinion of Bohmian mechanics a fair bit, despite the fact that I know very little about it. This came up again recently, so I got some suggested reading from Matt Leifer, on the grounds that I ought to learn something about it if I’m going to keep being asked about it.… Continue reading Quick Impressions of Bohmian Mechanics
The Problem of (Quantum) Moderation: On Many Worlds
I’ve written before about the problem of having in-between views on controversial subjects in blogdom. This is something that also comes up in Jessica’s excellent entry on online culture, and has been scientifically demonstrated in political contexts. I’m somewhat bemused, then, to see the same thing happen in a physics context. A while back, I… Continue reading The Problem of (Quantum) Moderation: On Many Worlds
The One Thing to Believe If You’re Only Going to Believe One Thing
Over in Twitter-land, S. C. Kavassalis notes a Googler who’s not afraid to ask the big questions: Weird Google search of the week: ‘the “one” scientific idea that we need to believe’. Uh um, I’m sure my blog couldn’t possibly answer that. It’s a good question, though, ad there are a couple of different ways… Continue reading The One Thing to Believe If You’re Only Going to Believe One Thing
Conference Organizers Should Not Live in Caves
A sad and sordid story from the Times Higher Education following the rescinding of invitations to a conference on quantum foundations: Details of the conference in August for experts in quantum mechanics sounded idyllic. Participants were due to discuss “de Broglie-Bohm theory and beyond” in the Towler Institute, which is housed in a 16th-century monastery… Continue reading Conference Organizers Should Not Live in Caves
Dorky Poll: Would You Like Constants With That?
I wanted to test whether I can put links into PollDaddy poll items for the Laser Smackdown wrap-up tomorrow, so I needed a test poll. But, of course, if I’m going to go to the trouble, I might as well post it, so here’s a dorky poll inspired by the fact that the book I’m… Continue reading Dorky Poll: Would You Like Constants With That?
There’s More to Science Than Evolution
The National Science Board made a deeply regrettable decision to omit questions on evolution and the Big Bang from the Science and Engineering Indicators report for 2010. As you might expect, this has stirred up some controversy. I wasn’t surprised to learn this, as I had already noticed the omission a couple of months ago,… Continue reading There’s More to Science Than Evolution
