drorzel | April 29, 2013Last year, Alan Alda posed a challenge to science communicators, to explain a flame in terms that an 11-year old could understand. this drew a lot of responses, and some very good winners. This year's contest, though still called the "Flame Challenge," asked for an answer to the question "What Is Time?"
This is a little closer to my corner of science, so I considered entering, but as previously noted, I'm crushingly busy at present. And either scripting/ shooting/ editing a video, or doing the necessary work to hack a written response down to the prescribed 300 characters was more time than I…
drorzel | September 27, 2012SCENE: The library at Chateau Steelypips. DADDY is typing on the computer, while THE PIP plays on the floor. Enter STEELYKID.
STEELYKID: I'm already four years old.
DADDY: Yes, yes you are.
THE PIP: Thbbbbbbbpppt!
STEELYKID: How old is The Pip?
DADDY: Eleven months. Not quite one year.
STEELYKID: When The Pip is four, how old will I be?
DADDY: You'll be seven.
STEELYKID: And when he's seven, how old will I be?
DADDY: You'll be ten.
THE PIP: (pulls himself to a standing position) GA BA DA BA Phbbbbt! (falls down)
STEELYKID: Daddy, how old are you?
DADDY: I'm forty-one.
STEELYKID: And when I'm…
drorzel | June 19, 2012In which we look at a slightly crazy-sounding proposal from my former boss, the experimental realization of which is getting close to completion.
------------
I spent more or less the entire first day of DAMOP a couple of weeks ago going to precision measurement talks. Most of these were relatively sedate (at least by the standards of a sub-field that routinely involves people proposing incredibly difficult experiments), but my boss when I was at Yale, Mark Kasevich, provided the bold proposals I usually expect, in this case suggesting an experiment using an atom interferometer to measure…
drorzel | May 21, 2012I was going to post something noting that the great WordPress transition will begin at 7pm tonight, and comments after that time will be lost like Roy Batty's tears. However, I have much happier news: tomorrow's Science Times (available on the Web already) will include a review of How to Teach Relativity to Your Dog!
I considered reading this book aloud to my dog, even though I doubted he would understand relativity, even as explained by the witty and clear-thinking Chad Orzel. Maxwell does seem to show some interest in Newton's first law: A body at rest tends to remain at rest, and a body in…
drorzel | May 18, 2012So, you find yourself living in the San Francisco Bay area, and you maybe have a dog who would like to know something about relativity, or you maybe want to someday have a dog who will want to know something about relativity, or you maybe want to know something more about relativity yourself, in case you ever find yourself cornered in a dark alley by a Rhodesian ridgeback who snarls "Explain time dilation to me, or I'll eat your face!" Well, in that case, you definitely want to be at Kepler's Books in Menlo Park on the evening of June 14th, when I'll be doing a book promotion thing for How to…
drorzel | April 9, 2012 I'm trying not to be Neurotic Author Guy and obsessively check online reviews of How to Teach Relativity to Your Dog every fifteen minutes. I've actually been pretty successful at it, so successful that I didn't notice the first posted review at Amazon until my parents mentioned it to me. It's a really good one, though:
I'm at the point know where I could answer some of the most basic questions that his dog has, but I remember a time when I couldn't and when the questions the dog asks would've been exactly the questions that I would have had. Pretty much every time a statement by the author…
drorzel | April 2, 2012So, the infamous OPERA result for neutrino speeds seems to be conclusively disproven, traced to a problem with a timing signal. Matt Strassler has a very nice explanation of the test that shows that the whole thing can almost certainly be traced to a timing error that cropped up in 2008. This problem is generally described as resulting from a "loose fiber optic cable," and Matthew Francis's reaction is fairly typical
The main culprit was a fiber optic cable that was slightly out of alignment. This is not quite a "loose wire", as it sometimes has been described: it's far more subtle and harder…
drorzel | April 1, 2012In comments to yesterday's post, Andrew G asked:
Speaking of writing, is there an errata list somewhere for "How to teach relativity to your dog"?
No, but there probably should be. I believe there's an error in one of Maxwell's equations (an incorrect sign, though you should've seen the first typeset version...), but given the length and complexity of the book, there are almost certainly other mistakes. So, if you've spotted an error, in physics, grammar, or anything else, leave a comment here, and I'll compile a list of things to fix if we ever get the chance.
drorzel | March 25, 2012I had a signing yesterday at the Barnes & Noble in Vestal, NY, which drew a smallish crowd mostly of friends and family. SteelyKid came, of course, and while she spent most of her time bopping about other parts of the store, she came over to the signing area while I was signing books for people after reading a bit. They had a big stack of copies of How to Teach Relativity to Your Dog, and she started picking them up and handing them to me.
"No, honey," I said, "Those are for other people. Give them to somebody else." So she happily ran one over to my mother. And then to one of my aunts.…
drorzel | March 20, 2012A couple of cool items in the promotion of How to Teach Relativity to Your Dog:
-- A little while back, I spoke to Alan Boyle, who writes the Cosmic Log blog for MSNBC, who posted a very nice story about the book last night. Mainstream media, baby!
It also uses this very cool picture of Emmy and me in my lab:
(Many thanks to Matt Milless for taking that and a bunch of others.)
-- This weekend (either Saturday or Sunday, depending on where you are), I'll be on the Science Fantastic radio show, talking about relativity with Michio Kaku. There's a lsit of stations that carry it linked from that…
drorzel | March 17, 2012I've done a bunch of publicity stuff for How to Teach Relativity to Your Dog, some of which frustratingly continue to not appear yet, but one thing from this week has gone live: a podcast interview on the Matt Lewis Show, where I talk about why and how I explain physics to the dog, and a little bit about why relativity is cool.
I continue to struggle a bit with the fact that relativity is a very visual subject-- most of the best explanations involve pictures, which aren't much help in an audio-only medium. I had trouble with this at Boskone, too-- when I was doing a reading, it was hard to…
drorzel | March 16, 2012A little more tab clearance, here, this time a few recent stories dealing with those elusive little buggers, neutrinos. In roughly chronological order:
The Daya Bay experiment in China has measured a key parameter for neutrino oscillation (arxiv paper), the phenomenon where neutrinos of one of the three observed types slowly evolve into one of the others. Mathematically, this is described as each of the three types we observe being an admixture of three more fundamental types. This mixing is described in terms of the sine of some "mixing angle," because physicists love geometry, and two of…
drorzel | March 6, 2012The new book is out, which means it's time for lots of promotional efforts and links to radio shows and news articles and that sort of thing. Such as this one: I'll be talking about relativity and dog physics tomorrow night, Wednesday the 7th, on the Big Science radio program(me) at 9pm London time (in the frame of reference in which London is at rest, anyway). This'll be the first radio show for the new book, though I've done a few phone interviews for print publications (links as they become available...).
If you're in London, and have nothing better to do, tune in. (We are, after all, more…
drorzel | February 29, 2012The Subject: header pretty much says it all: How to Teach Relativity to Your Dog is reviewed in Nature Physics. I am inordinately pleased with the existence of this-- not because I expect it to sell a significant number of books, but because a serious technical publication recognized it as worth writing up, despite the silly title.
Of course, Nature being Nature, it's paywalled, so you can only read the full thing via the above link if you have institutional access, or know a nice person who will email you a copy when you ask for it on Twitter. The review itself is about what I would expect…
drorzel | February 28, 2012I'm home with The Pip today, so no extended typing for me, but I pre[ared for this by typing something up ahead of time, and getting John Scalzi to post it for me, as part of his Big Idea series:
In a way, a book about Einstein's theory of relativity is uniquely suited to a series about Big Ideas. Relativity, at its heart, is a theory built on a single Big Idea:
The laws of physics do not depend on how you're moving.
For all its fearsome reputation, everything stems from that single,simple idea. Whether you're moving or standing still, floating in space or on the surface of a planet, you…
drorzel | February 28, 2012The Pip says, "Hi, folks. My daddy's book is released today, and he's shameless enough to use me to promote it:"
"I can't read it yet, because I'm just a baby, but I can report that it was very satisfying to drool on. So you should definitely buy a copy, maybe two."
"Also, dig the awesome stuffed alligator toy I got from my Aunt Erin and Aunt 'Stasia. It crackles, and it has a mirror! It's so cool!"
drorzel | February 27, 2012If you're allergic to hype, you might want to tune this blog out for the next couple of days, because How to Teach Relativity to Your Dog is officially released tomorrow, so it's all I'm going to talk about for a little while. Because, well, I'm pretty excited.
And tonight's exciting finding is that it's mentioned in the Washington Post:
If "Physics for Dummies" left you baffled, maybe it's time to go a step further: Why not physics for pets? In "How to Teach Relativity to Your Dog," physics professor Chad Orzel attempts to explain Einstein's theory of relativity via a dialogue with his dog,…
drorzel | February 26, 2012Hey, you might not know this, but I wrote a book...
The official release date for How to Teach Relativity to Your Dog isn't until Tuesday, but a friend reported buying a copy in Missouri, so when I was headed out to do some work this afternoon, I went to the cafe at the local Barnes&Noble so I could check for myself, and there it was:
That's How to Teach Relativity to Your Dog spotted in the wild. I'm not going to say "in its natural habitat," because it's really a domestic animal, which belongs in a loving home, with people to care for it. Copies in the bookstore are feral editions,…
drorzel | February 24, 2012It's not a good week for me to be writing about anything remotely controversial, but if I want to keep my physics blogging license, I need to say something about the latest fast neutrino news. This has followed the usual trajectory of such stories, with the bonus farcical element of people who blasted the media for buying into the initial release seizing triumphantly on an initial rumor in the press that was garbled into incomprehensibility. With a little more time, it's become more clear how their result has become less clear, and the best place to look for a description of this is Matt…
drorzel | February 23, 2012I'm grading exam papers at the dining room table when Emmy trots in. "Hey, dude," she says. "Where do we keep the superconducting wire?"
I'm not really paying attention, so I start to answer before I understand the question. "Hmm? Wire is in the basement, next to the--wait, what?"
"The superconducting wire. Where do we keep it?"
"We don't have any superconducting wire. And you're a dog. What do you need superconducting wire for, anyway?"
"I'm building a particle collider! I need superconducting wire for the beam-steering magnets."
How to Teach Relativity to Your Dog goes on sale next Tuesday…
