Throwback Thursday

OK, the photo above is a recent picture of me– yesterday, in fact. But the spiral-carved rock I’m standing next to was carved that way a bit more than five thousand years ago, so that ought to count as a throwback… We’ve been in Dublin the last few days, and on Thursday we took a… Continue reading Throwback Thursday

Eureka! It’s a Talk!

Kate and I had a very nice time doing touristy things in Bath yesterday during the day– old church, very old hot spring, Georgian architecture– then went on to Bristol where I gave a talk on the forthcoming book, as you can see in the picture above. I would ordinarily include a SlideShare link to… Continue reading Eureka! It’s a Talk!

Women of the Arxiv

Fraction of Ph.D.'s in physics awarded to women, as a function of time. From the AIP Statistical Research center.

Over at FiveThirtyEight, they have a number-crunching analysis of the number of papers (co)authored by women in the arxiv preprint server, including a breakdown of first-author and last-author papers by women, which are perhaps better indicators of prestige. The key time series graph is here: This shows a steady increase (save for a brief drop… Continue reading Women of the Arxiv

Impossible Thruster Probably Impossible

Torsion pendulum from the Eot-Wash experiment at the University of Washington.

I’ve gotten a few queries about this “Impossible space drive” thing that has space enthusiasts all a-twitter. This supposedly generates thrust through the interaction of an RF cavity with a “quantum vacuum virtual plasma,” which is certainly a collection of four words that turn up in physics papers. An experiment at a NASA lab has… Continue reading Impossible Thruster Probably Impossible

The Fermi Alternative

Given the recent Feynman explosion (timeline of events), some people may be casting about looking for an alternative source of colorful-character anecdotes in physics. Fortunately, the search doesn’t need to go all that far– if you flip back a couple of pages in the imaginary alphabetical listing of physicists, you’ll find a guy who fits… Continue reading The Fermi Alternative

Ten Inessential Papers in Quantum Physics

I should really know better than to click any tweeted link with a huff.to shortened URL, but for some reason, I actually followed one to an article with the limited-reach clickbait title Curious About Quantum Physics? Read These 10 Articles!. Which is only part one, because Huffington Post, so it’s actually five articles. Three of… Continue reading Ten Inessential Papers in Quantum Physics

The Physicists of Journalism

This Alberto Cairo piece on “data journalism” has been kicking around for a while, and it’s taken me a while to pin down what bugs me about it. I think my problem with it ultimately has to do with the first two section headers in which he identifies problems with FiveThirtyEight and Vox: 1. Data… Continue reading The Physicists of Journalism

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
