Baseball Is Pretty Random

Batting averages compared to career totals for six famous players.

After Thursday’s post about sports and statistics, a friend from my Williams days, Dave Ryan, raised an objection on Facebook: There’s an unstated assumption (I think) in your analysis: that there is some intrinsic and UNALTERABLE statistical probability of getting a hit inherent in every hitter. If that is the case, then yes — a… Continue reading Baseball Is Pretty Random

More Kids and Conferences

There's a WHAT?!? Behind me?

The kids and conferences issue, discussed here a while ago has continued to spark discussion, with a Tenure She Wrote piece on how to increase gender diversity among conference speakers and a Physics Focus blog post on a mother who wound up taking her toddler to a meeting. There are some good points in both,… Continue reading More Kids and Conferences

Sports and Statistics: Nobody Deals Well With Randomness

The great xkcd nails sports commentary.

One of the chapters of the book-in-progress, as mentioned previously, takes the widespread use of statistics in sports as a starting point, noting that a lot of the techniques stat geeks use in sports are similar to those scientists use to share and evaluate data. The claim is that anyone who can have a halfway… Continue reading Sports and Statistics: Nobody Deals Well With Randomness

Dorky Poll: Rorschach Numbers

It’s been a really long time since I’ve done a Dorky Poll here, but I’m pretty fried at the moment, so here’s a kind of mathematical personality test: two numbers that do not uniquely define a sequence, but suggest some possibilities that reveal your innate character type and/or appropriate career path: Personality Test: What number… Continue reading Dorky Poll: Rorschach Numbers

On Mentoring

I forget who pointed me to the Tenure She Wrote piece on mentoring, but it’s something I’ve been turning over for a couple of weeks now. Probably because I became aware of it right around the time my two summer students started work last week. It keeps colliding with other conversations as well, though, so… Continue reading On Mentoring

The Making of a Sign Error

The Bose-Hubbard Hamiltonian, in the notation I used in the squeezed state paper.

One thing I left out of the making-of story about the squeezed state BEC paper last week happened a while after publication– a few months to a year later. I don’t quite recall when it was– I vaguely think I was still at Yale, but I could be misremembering. It’s kind of amusing, in an… Continue reading The Making of a Sign Error

Photons Are Here to Stay, Deal With It

I spend a lot of time promoting Rhett Allain’s Dot Physics blog, enough that some people probably wonder if I get a cut of his royalties (I don’t). I’m going to take issue with his latest, though, because he’s decided to revive his quixotic campaign against photons, or at least teaching about photons early in… Continue reading Photons Are Here to Stay, Deal With It

The Making of “Squeezed States in a Bose-Einstein Condensate”

A 3-d rendering of the squeezed state data, created in an unsuccessful bid for the cover of Science.

Yesterday’s write-up of my Science paper ended with a vague promise to deal some inside information about the experiment. So, here are some anecdotes that you would need to have been at Yale in 1999-2000 to pick up. We’ll stick with the Q&A format for this, because why not? Why don’t we start with some… Continue reading The Making of “Squeezed States in a Bose-Einstein Condensate”

My Claim to Scientific Fame: “Squeezed States in a Bose-Einstein Condensate”

A version of Figure 4 from the paper discussed in the post, taken from an old talk.

In Monday’s post on squeezed states, I mentioned that I really liked the question because I had done work on the subject. This is, in fact, my claim to scientific fame (well, before the talking-to-the-dog thing, anyway)– I’m the first author on a Science paper with more than 500 citations having to do with squeezed… Continue reading My Claim to Scientific Fame: “Squeezed States in a Bose-Einstein Condensate”
