My LonCon Schedule

Since lots of other people are posting their Worldcon progrm(me) schedules, I might as well share mine, too. Frankly, I find it a little baffling: Kaffeeklatsch Thursday 18:00 – 19:00, London Suite 5 (ExCeL) Kay Kenyon, Chad Orzel Banksian Saturday 11:00 – 12:00, Capital Suite 9 (ExCeL) ‘Banksian’ has become a commonplace descriptor in SF… Continue reading My LonCon Schedule

Tennis Ball Plus Soccer Ball Equals Blown Minds

Screen cap of the video in the post, showing me dropping a tennis ball on top of a soccer ball.

As noted last week, I went to SteelyKid’s day camp on Tuesday to talk about being a college professor. This was a little awkward, because I was scheduled to talk to kids ranging from not-quite-three to six-and-a-bit, and really, what do they care about the daily routine of physics faculty? So, I did a simple… Continue reading Tennis Ball Plus Soccer Ball Equals Blown Minds

Impressive Physics Tricks for Little Kids?

We got an email from the people running SteelyKid’s summer camp asking for volunteers to speak at a career day sort of event early next week. I said “Sure, I can do that, and talk about the glamorous life of a physics professor and book author.” They said “Great, you’ll be talking to several groups,… Continue reading Impressive Physics Tricks for Little Kids?

Uncertain Dots 18

In which our series of Google hangouts becomes old enough to vote and buy cigarettes– but not drink! Miscellaneous things mentioned in this: — My forthcoming book at Amazon and Barnes and Noble. I turned in the copyedits and figures a week or so ago, and cashed an advance check today, so it’s definitely going… Continue reading Uncertain Dots 18

Two Cultures of Incompressibility

Also coming to my attention during the weekend blog shutdown was this Princeton Alumni Weekly piece on the rhetoric of crisis in the humanities. Like several other authors before him, Gideon Rosen points out that there’s little numerical evidence of a real “crisis,” and that most of the cries of alarm you hear from academics… Continue reading Two Cultures of Incompressibility

What Scientists Should Learn From Economists

Right around the time I shut things down for the long holiday weekend, the Washington Post ran this Joel Achenbach piece on mistakes in science. Achenbach’s article was prompted in part by the ongoing discussion of the significance (or lack thereof) of the BICEP2 results, which included probably the most re-shared pieces of last week… Continue reading What Scientists Should Learn From Economists

Son of Interstellar Laser Communications

I didn’t plan to do a follow-up to yesterday’s post about the optics of sending messages with lasers, but then I starting idly thinking about detection, prompted in part by a bunch of conversations with my summer students about single-photon detectors. which led to scribbling on the back of an envelope, which led to Googling,… Continue reading Son of Interstellar Laser Communications
