drorzel | February 20, 2012This was the title of the group discussion I led at Boskone on Saturday, and since it's probably relevant to the interests of people reading this blog, I figure it's worth posting a quick recap. Of course, between the unfamiliar format and Friday's travel with the Incredible Screaming Pip, I didn't actually make any notes for this, so what follows is my sketchy recollection of what I said; omissions and misstatements are a reflection of my dodgy memory, not an attempt to distort anything.
The title is obviously a little tongue-in-cheek, because the goal is really to not wreck your career with…

Chip MacGregor .com: Does the publisher lose money if my book doesn't earn out?
Remember, every business can lose money. Retail shops, service business, even publishers. I mean, if you own a shoe store, you order in shoes that don't sell, and you have to drastically reduce prices, you can lose money on each pair of shoes sold. Publishing is no different. The publishing house pays out advances, they pay an editor, hire a cover designer, buy ink and paper, then pay…
drorzel | February 18, 2012I'm at Boskone this weekend, and this morning went to a fairly frustrating panel on "SF/F/H As a Mirror on Society," described thusly:
It's simplistic to say genre fiction maps to current politics. Vampires are bankers, zombies are the revengeful victimized classes, and werewolves are the media in feeding frenzy? C'mon. But did we write more optimistic SF when the space race was young? Or victorious spacewar stories when we were losing Vietnam? If fiction in any way reflects societal anxieties or moods, what do we make of steampunk, or sparkly vamps, or dystopian YA, or upticks in stories…

Xpress Reviews: Nonfiction | First Look at New Books, February 17, 2012 -- Library Journal Reviews
Playing Gracie Allen to Orzel's George Burns is the endearing Emmy, the canine star of his previous book. No matter whether Emmy thinks she will be younger by pulling fast on her leash or that she will suddenly fit through a hole in the fence by running as fast as she can toward it, Orzel talks her (and readers) through the principles of relativity, including time dilation and length contraction. No prior mathematical knowledge is required for this book, but some basic knowledge in physics…
drorzel | February 16, 2012One of SteelyKid's favorite bedtimes reads is Good Night, Gorilla, which is very short and mostly pictures. We've read it about a million times, so to mix things up (and further my goal of convincing her that I'm a blithering idiot), I'll give it different titles when I hold it up before reading it. She giggles and correct me, and it's all very heartwarming and cute.
Tonight, I held it up and declared "This is... Konnichiwa, Kangaroo."
"No, Daddy, it's Good Night, Gorilla."
"Oh, my mistake. It's Bonsoir, Baboon."
"No, Daddy," she said, "Bonsoir Baboon is a movie. With a baboon, and the…
drorzel | February 16, 2012Regular reader Johan Larson sends in a good question about academic physics:
You have written about teaching various courses in modern physics, a subject that has a fearsome reputation among students for skull-busting difficulty. That suggests a broader question: what is the most difficult course at your university? Or even more broadly, how would one determine what course is the most difficult?
This is a good question, but hard to give a single answer to. The most difficult course at the college as a whole would be nearly impossible to determine, because different students find different…

Problem solving like a physicist | Science Edventures
Another way, which looks the same on the surface, is to break the nasty problem into a sequence of steps. "First, find the relationship between A and B. Then, calculate B for the given value of A. Next, substitute A and B into C and solve for C in terms of A..." That's a sequence of smaller problems that will lead to a solution of the nasty problem. But it's not scaffolding: it's spoon-feeding and it teaches none of the problem-solving skills we want the students to practice. I've heard from number of upper-level instructors declare they…

Proton Collisions Vs. Quark/Gluon/Antiquark Mini-Collisions | Of Particular Significance
Keep in mind that the total number of 7 TeV = 7000 GeV proton-proton collisions that took place in ATLAS while they were accumulating the data for the plot above was about 100,000,000,000,000. [The total 2011 data set was 5 times larger, but the corresponding plot won't appear for a few months.] Of all these collisions, just two had mini-collisions that passed above 3500 GeV -- half the collision energy of the protons. In principle the energy of the mini-collisions can go up all the way to 7000 GeV,…
drorzel | February 14, 2012As I've said a bazillion times already this term, I'm teaching a class that is about research and writing, with a big final paper due at the end of the term. Because iterative feedback is key to learning to write, they also have to turn in a complete rough draft, which I will mark up and have them revise.
One of the many, many problems with teaching writing is that too many students regard the writing of drafts as pointless busy-work. Others have no real concept of what a rough draft is-- when I've collected drafts in the past, I often get things that would barely qualify as an outline, let…
drorzel | February 13, 2012So, the big How to Teach Physics to Your Dog Photoshop contest concluded on Friday. We got five really good entries, and the judges (me and Kate) had a hard time reaching a decision. After long deliberation, though, we've come up with a solution.
But first, the entries:
Jane Di Giuseppe has Emmy as the dog pulling Einstein's strings:
John Pearce has Emmy playing with Einstein as well:
And Joseph Roith tells Maxwell's Demon to respect Emmy's authoritah!:
But in the end, it came down to two pictures: Tristan Croll's take on the famous chalkboard photo:
It's a little-known fact that not…

This will be a section from the forthcoming book, probably involving Emmy and particle physics. Or possibly William Butler Yeats.

The Virtuosi: Time Keeps On Slippin'
Alright, so how do we go about quantifying how "good" a watch is? Well, there seem to be two main things we can test. The first of these is accuracy. That is, how close does this watch come to the actual time (according to some time system)? If the official time is 3:00 pm and my watch claims it is 5:00 am, then it is not very accurate. The second measure of "good-ness" is precision or, in watch parlance, stability. This is essentially a measure of the consistency of the watch. If I have a watch that is consistently off by 5 minutes from the…
drorzel | February 12, 2012We send SteelyKid to preschool at the Jewish Community Center in Schenectady, because when we looked at day care programs back in the day, they had the one we liked best. This is a mixed blessing in a number of ways-- they close for a lot of religious holidays when nothing else closes, creating some awkwardness with child care and our jobs. On the plus side, though, it's a chance to learn about another culture, and as an extra bonus, most of what we learn is filtered through SteelyKid, making it extra cute.
For example, on the way home Friday, she was chattering quietly to herself in the back…

Jeremy Lin, Landry Fields unveil nerdiest handshake in NBA history - San Jose Mercury News
Jeremy Lin and Landry Fields of the New York Knicks may comprise the most intelligent starting backcourt in NBA history. It's certainly hard to top a duo that boasts college degrees from Harvard (Lin) and Stanford (Fields). So it's not surprising when Lin and Fields unveiled what has to be the nerdiest pre-game handshake in league history. The choreographed skit features the two skimming through an imaginary book, taking off their glasses and then placing them inside pocket protectors.
Confessions of…
drorzel | February 10, 2012Prompted by a number of people using the phrase "vast majority" recently, I wonder where the line between "majority" and "vast majority" is. Thus, a poll:
What is the minimum level of support that constitutes a "vast majority"
Assume for the sake of argument that the issue in question is a simple yes-or-no question, with only a small "no response/ don't know" fraction.
If there are other classes of "majority" that you recognize, feel free to define them in the comments. The poll is just about the term "vast," though.

Why the Proponents of a Gay Marriage Ban Will Soon Be Speechless - Slate Magazine
So there you have it: That's the best case that can be made against gay marriage. An appeals court dissent that rests on the premise that states needn't act rationally, or offer evidence of rationality, or even be rational in creating classifications, so long as someone publishes a study and someone else believes it. That's the best they've got, it seems. That is not legal argument or empirical evidence. It is the death rattle of a movement that has no legal argument or empirical evidence.

drorzel | February 9, 2012In a book that I read recently (either The Cloud Roads or The Serpent Sea-- I finished the first and immediately started the second), as some characters are traveling from one place to another, there's a passing mention that they weren't able to hunt at night because the moon wasn't out and it was too dark. Which sort of bugged me, and I was reminded of it tonight when I took Emmy out for our post-dinner walk-- it's very clear tonight, and a lot of stars were visible, even here in the light-polluted suburbs, but the moon wasn't up yet.
And the thing is, while it's darker when the moon isn't…

Why The Planet Doesn't Care About Your Eco-Friendly Lifestyle | Co.Exist: World changing ideas and innovation
Co.Exist:What does the average environmentalist get wrong? Wagner: Environmentalists, all too often, think that the best way to go about solving the problem is to get everyone to do as they--we, I included--do. I don't eat meat. I don't drive. But individual do-gooderism won't solve global warming. And it may actually be counter-productive, for two reasons. First, there's a well-documented psychological phenomenon called "single-action bias." You do one thing, and you move on. You…
drorzel | February 8, 2012Through a weird quirk of scheduling, I haven't actually taught the intro modern physics course since I started writing pop-science books about modern physics. So, this week has been the first chance I've really had to use material I generated for the books to introduce topics in class.
In the approximately chronological ordering of the course, we're now up to the late 1800's, and the next book we're talking about is Einstein's Clocks, Poincar$eacute;'s Maps, which talks about how Einstein and Henri Poincaré were (arguably) influenced by developments in timekeeping as they looked for the…
drorzel | February 8, 2012I have a Google alert set up to let me know whenever my name or the title of one of my books turns up in one of the sources they index. This is highly imperfect, sometimes missing interesting articles, and often blorting out 57 different pages on which my name appears in a sidebar link. It comes in handy from time to time, though, such as this morning, when it coughed up a whole bunch of pages linking to the Polish edition of How to Teach Physics to Your Dog:
Finally, dogs in the ancestral homeland of my father's family can learn all about quantum physics. I'm a little surprised to learn…
