NPR hack apologizes for Wall Street « LBO News from Doug Henwood
For a while, I've been thinking about writing a piece on how NPR is more toxic than Fox News. Fox preaches to the choir. NPR, though, confuses and misinforms people who might otherwise know better. Its "liberal" reputation makes palatable a deeply orthodox message for a demographic that could be open to a more critical message. The full critique will take some time. But a nice warm-up opportunity has just presented itself: a truly wretched piece of apologetic hackery by Adam Davidson, co-founder of NPR's Planet Money economics…
drorzel | February 6, 2012So, my Giants edged out Kate's Patriots again in the Chateau Steelypips Bowl, in a game that was certainly not without its drama. I'm not going to gloat about it, because a couple of different bounces here or there easily could've changed the outcome. Also, I didn't see the third quarter at all, really, because it was SteelyKid's bedtime, and I was upstairs reading her stories.
But as good as the game was, we now have to turn toward the future, and specifically what wacky thing will go wrong to prevent the Giants from doing anything significant next year. "What do you mean?" you ask. Well,…
drorzel | February 5, 2012Proving that you can find physics in everything, Sean Carroll points to a strange anomaly in the Super Bowl coin toss: the NFC has won 14 coin tosses in a row. The odds of this happening seem to be vanishingly small, making this a 3.8-sigma effect, almost enough to claim the detection of a new particle, and certainly enough to justify the generation of a press release.
Of course, there are two problems with Sean's analysis, one classical and one quantum. The classical objection is that what we have a record of is one team winning the toss every time, which does not mean that the coin is doing…
drorzel | February 5, 2012Like many Americans, I'm going to be hugely preoccupied today. Thus, a poll for your blog-like entertainment needs:
The Super Bowl is today. Who's going to win?
If you choose the last option, please arrange to have contacted me in the past to tell me who to have laid a significant bet on so I will have won a large sum of money.

Duke's Cameron Crazies Lose Their Enthusiasm - NYTimes.com
There is growing sentiment that Cameron has lost some of its craziness, and there is definitive evidence that it has lost some of its Crazies. About 1,200 seats are earmarked for Duke's undergraduates, but this season students have filled about 700 a game while classes are in session. Over the last three years, the university has filled the gaps by regularly selling hundreds of student-section tickets to nonstudents, giving the famed Section 17 an unusual look.
Stephen Colbert is winning the war against the Supreme Court and…
drorzel | February 3, 2012It's been a little while since I wrote up what I've been doing in my "Brief History of Timekeeping" class, because I was out of town, and then catching up from being out of town. Some of this material has already appeared here, though, so I can hopefully catch up a lot of stuff in one post.
The material that will be most interesting to random readers of the blog is the "How to" section, from a couple of weeks ago, which were the lecture form of the How to Read a Scientific Paper and How to Present Scientific Data posts here. The paper-reading class was on Monday and the data-presentation…

Whither The Occupation - Ta-Nehisi Coates - National - The Atlantic
"There's an argument that the process of federal legislation, at this point, is crippled by deep systemic problems. The filibuster is an obvious example. It's also worth pointing out that there is a space for activism beyond electoral politics. But laws exist for a very good reason. They are--roughly put--a compact between citizens and the state detailing the guidelines for governance. Laws--and their alteration or abolishment--are the means by which we change the compact. The alternative, to my mind, is revolution. At the…
drorzel | February 2, 2012It's now officially February, and the release date for How to Teach Relativity to Your Dog is only a few weeks off-- the official release date is Feb. 28. Of course, I've got a copy already:
If you would like a copy of your very own, you can either wait until the release, or take part in this shameless publicity stunt: The second-ever Dog Physics Photo Contest!
Last time around, we did a LOLEmmy contest for a bound galley proof of the first book. This time, I'm giving away a signed copy of the finished book, so we'll go for something a little trickier: I've picked three pictures from my…
drorzel | February 2, 2012As I keep saying in various posts, I'm teaching a class on timekeeping this term, which has included discussion of really primitive timekeeping devices like sundials, as well as a discussion of the importance of timekeeping for navigation. To give students an idea of how this works, I arranged an experimental demonstration, coordinated with Rhett at Dot Physics. We've been trying to do this literally for months, but the weather wouldn't cooperate. Until this past weekend, when we finally managed to make measurements that allow us to do some cutting-edge science. For 200 BC, anyway...
So, what…
drorzel | February 1, 2012It's apparently a good day for asking questions of the readership, so here's another one: as SteelyKid has gotten older and more active, she's become a real drain on productivity, especially at bedtime. Bedtime is now a process rather like a certain spoof book, extending well over an hour, and involving repeated requests to come back into her room for some silly reason or another. If I don't respond quickly enough, she'll work herself up into a real tantrum, so I pretty much need to stay upstairs in our bedroom until she's asleep. Which means either I can't get any work done, or I have to…
drorzel | February 1, 2012I'm using Dava Sobel's Longitude this week in my timekeeping class. The villain of the piece, as it were, is the Reverend Dr. Nevil Maskelyne, who promoted an astronomical method for finding longitude, and played a major role in delaying the payment to John Harrison for his marine chronometers. It's a good story, with lots of science and engineering and politicking.
There's one critical flaw, though, in terms of me teaching this book, which is that I don't really know how to say Maskelyne's name. And even Wikipedia is letting me down, here, by not providing a phonetic rendering of his name.…

They don't warn you about the bewildering, befuddling vertigo that comes with having done everything they say to do, all to no avail, and having no idea what to do next. There you are, willing and eager to wear away whatever leather there still is on your shoes, but you have no idea what direction to walk. There sits the phone, but you have no one left to call. And you've refined your online job-searching skills to the point where it takes you only a fraction of the time to confirm that there's nothing out there. Now what? What happens…

Quantum Diaries
Science is complex. There's no getting around that. But it's essential that everyone engage constructively with it. That's particularly true of the political and business leaders in Davos, whose decisions on science-based subjects can influence everything from the well being of our children to the future of the planet. It's vital that those decisions are taken from an informed position and on rational grounds. The challenge that science faces is that we live in a world where it's de rigueur to know your Shakespeare, Molière or Goethe, but quite all right to be proudly…
drorzel | January 30, 2012There's been a lot written recently about academic publishing, in the kerfuffle over the "Research Works Act"-- John's roundup should keep you in reading material for a good while. This has led some people to decide to boycott Elsevier, including Aram Harrow of the Quantum Vatican. I'm generally in favor of this, but Aram says one thing that bugs me a bit:
Just like the walled gardens of Compuserve and AOL would never grow into the Internet, no commercial publisher will ever be able to match the scope and ease of access of arxiv.org. Nor can they match the price. In 2010, there were about…

BOOK REVIEW: How To Teach Relativity To Your Dog By Chad Orzel - Science News
It may sound like a strange setup, but the somewhat kooky concept works well for explaining a field of physics that can sound, well, kooky to the uninitiated. Emmy is the stand-in for the everyman (or everydog) who has never quite managed to grasp the idea of spacetime, or why moving clocks tick slower than stationary ones. The imagined back-and-forth banter between author and dog keeps the book engaging while Orzel lays out the theoretical framework of particle physics, explains why neither dogs nor neutrinos can…
drorzel | January 27, 2012I was going to write something about the politics of scientific publishing, but instead, I want to focus on what's really important in modern publishing:
That's right, I got a couple of early copies of How to Teach Relativity to Your Dog in the mail this morning. It's a real book, with pages and everything... You can see it above, next to How to Teach Physics to Your Dog, and various clutter on my desk, for scale.
There's not much else to say, other than "Woo-hoo!" They're printing lots more, of course, and it will be available wherever books are sold starting Feb. 28th.

slacktivist » Mark Driscoll, John Woolman, Zacchaeus and grace
That [Quaker abolitionist John] Woolman was so miraculously persuasive suggests to me that he likely wasn't as monomaniacally focused on a single subject as the old preacher in the story I shared in the previous post. And the more I think about that story and Woolman's, the more I want to qualify my commendation of such a single-minded relentlessness. Woolman certainly was single-minded and relentless. He did one thing for decades, obsessively. Yet he also convinced people to change -- he convinced hundreds of people to change…
drorzel | January 25, 2012The toy model of statistical entropy that I talked about the other day is the sort of thing that, were I a good computational physicist, I would've banged out very quickly. I'm not a good computational physicist, but by cargo-culting my way through some of the VPython examples, I managed to get something that mostly works:
The graph at the bottom of that window is the entropy versus "time" for a lattice of 20 sites with a 25% hopping probability (either left or right). The window with the colored balls at the upper left is a graphical representation-- red dots are "occupied" sites, white "…
drorzel | January 24, 2012So, back when How to Teach Physics to Your Dog was coming out, I did a few "dramatic readings" of bits of the book, such as this one on the Quantum Zeno Effect:
This was made with Windows Movie Maker, because it was free (came with the computer) and dead simple. However, Movie Maker on my new computers is hopelessly broken-- I've made a couple of attempts to do the same sort of thing with my laptop, but I've never managed to get more than a couple of steps in before it crashes. (To be fair, this is one of only two things that are worse under Windows 7 than Vista, and the only one that's…
