drorzel | July 5, 2013The picture above shows the new sign on SteelyKid's door. She had to ask us how to spell the words-- she's not five for another month, yet-- but she is now the proud owner of a hand-lettered "DO NOT ENTER" sign for her bedroom. About half a dozen years earlier than I was hoping for...
I made good progress on the draft chapter of the moment this morning, which means that I'm allowed to blog today, per the terms of my agreement with myself. But this is kind of a lost day, anyway, so while I am going to write a post explaining some cool physics, I'll schedule it for Monday instead of posting it…
drorzel | July 4, 2013It's Independence Day here in the US, so here are some patriotic kid photos for you.
"Wait a minute," you say, "That featured image doesn't have any flags or fireworks or gilled meat products! How is that patriotic?"
"Ah," I reply,"It was taken at the American Museum of Natural History in NYC last weekend." Game. Set. Match.
Here are a couple of other pictures from that visit:
The Pip is impressed with skeletons of ancient megafauna.
SteelyKid racing a triceratops skeleton.
And since I've already had to bite back a couple of "Oh, go fuck yourself" responses to political tweets, I'm…
drorzel | July 3, 2013There was a brief flurry of discussion yesterday kicked off by Matt Yglesias posting People Don't Major in Science—Because It's Hard, which more or less says what the title would lead you to believe (either title, since he's blogging for Slate where they like to give pages titles that don't match the post titles...). This was inspired by a National Bureau of Economic Research paper, the full text of which seems to be paywalled, sort of-- they emailed it to me at my work address for free. And since I could get it, I figured I should dig into it a bit to see what it really said.
I'm not going…
drorzel | July 2, 2013Having said that I want to focus more on positive stuff, and talking up cool things in science, I'm going to make an effort to do more write-ups of research papers. I've got a few ideas along those lines, and of course I get regular emails from journals and press offices bringing other papers to my attention. But I don't want to neglect my audience, here...
So, I'll throw this open as a place to request discussions of particular topics or papers. If there's some topic in physics that you'd like me to write up an explanation of, or a paper or preprint that you'd like me to do the detailed Q…
drorzel | July 2, 2013In my darker moods, I sometimes suspect that all academics, regardless of their specialty, are engaged in the same pursuit: searching out and exposing the systematic oppression of... whatever department or program the faculty member speaking at the moment happens to belong to. No matter what field of study they work in, faculty seem to cultivate and even cherish a sense of victimhood. Somebody else has a bigger office, or a newly renovated building, or more support from the administration for their pet projects. Faculty with big offices and renovated space complain about the location, and…
drorzel | July 1, 2013One of the great frustrations of my intellectual life, such as it is, is the problem of the disappearing quote. This is a function of having acquired a broad liberal education (in the sense of "liberal arts college" not the sense of "person to the left of Rush Limbaugh") in a somewhat haphazard manner. My knowledge of physics is reasonably systematic, but for just about everything else, I've taken a bunch of classes, and read quite a bit of stuff, but never done all that much to keep the knowledge thus acquired organized. Which frequently leaves me in the position of knowing I read something…
drorzel | June 27, 2013The day I bought my iPad, as I was taking it out of the box, SteelyKid (then 3) came bopping into my office, spotted it, and declared "I want to play Angry Birds!" It's a remarkable demonstration of the genius of their product: not only have they created a game that a three-year-old can play, they've managed to make every three-year-old in the industrialized world aware of their product.
It's also a testament to my current obsession, the universality of science, and not just because you can use the game to illustrate physics. After all, the process of playing the game serves as a good…
drorzel | June 26, 2013 I'm always a little ambivalent about writing up papers that have also been written up in Physics: on the one hand, they make a free PDF of the paper available, which allows me to reproduce figures from the paper in my post, since I'm not breaking a paywall to do it. Which makes it much more attractive to write these up. On the other hand, though, they do a pretty good job writing accessible descriptions, so there's not that much for me to add.
In the case of this paper, I'll write it up anyway (albeit somewhat more briefly than usual, because they already did a nice job), just because the…
drorzel | June 25, 2013Kate had to leave at 7am this morning to go to a "retreat" for her office, so I took the kids to Dunkin' Donuts for breakfast. That got us all out the door at the same time, avoiding the freakout from The Pip if he saw Mommy leave without him. Kate will be late getting home tonight, as well, so I've got dinner with the kids as well, and SteelyKid has already declared that she wants to go to the Irish pub downtown for sweet potato fries and fish & chips.
I mention this not because I want to fill the blog with trivial details of my personal life-- that's what Twitter is for-- but because it…
drorzel | June 22, 2013One of the great things about "Fermi Problems" is that there are multiple ways of attacking them. So, for example, when considering the death ray plot yesterday, I used medical devices as an example system to assess the plausibility of the plot, while Physics Buzz talked total energy. But those aren't the only ways to approach this, and turning it over last night, I thought of another approach.
As I mentioned in yesterday's post, I normally think of light in terms of photon flux or energy flux, and one way to go at this would be to ask how many photons of light you'd be dealing with. The…
drorzel | June 21, 2013One bad thing about SteelyKid's preschool graduation yesterday was that it drained my phone battery, causing me to miss an interview request from a local TV station looking for somebody to talk about a a couple of local guys arrested for a plot to build a "death ray" from X-ray components. This is pretty far from my area of expertise, but, hey, I'd be willing to go on tv and talk about just about anything physics-related. And, as always, I promise to be at least 90% less wrong than Michio Kaku.
Of course, on another level, I'm kind of glad that I didn't get the message in time, because when I…
drorzel | June 20, 2013SteelyKid's preschool "graduation" was today, and in addition to a certificate with her name on it, she got a CD of her class's favorite songs and a composite picture of her class. I'd include an image, but it wouldn't reproduce well, and anyway, I try not to post pictures of other people's kids. What I will do, however, is a rundown of what it says about Kids these Days, since the picture is made up of shots of the individual kids each holding a sign declaring what they want to be when they grow up.
The class featured six boys and seven girls, so here are the results by gender, boys first…
drorzel | June 20, 2013One of the oddities of writing the book-in-progress is that it involves a lot more history-of-science than I'm used to. which means I'm doing things like checking out 800-page scientific biographies from the college library so I can use them to inform 500 word sections of 4000 word chapters. One of these is Cavendish: The Experimental Life by Christa Jungnickel and Russell McCormmach, a biography of Henry Cavendish (and his father), whose most famous experiment is one of the things I plan to describe in the book. Henry himself turns out to be quite a character, though, thus the 800-page…
drorzel | June 18, 2013I've got a ton of stuff that needs to get done this week, but I don't want the blog to be completely devoid of new content, so here's a quasi-poll question for my wise and worldly readers:
What scientist is most in need of a good popular biography?
By "popular biography," I mean things like Norton's Great Discoveries books, several of which Ive reviewed here, including Krauss on Feynman and Reeves on Rutherford, two books that I keep coming back to for useful tidbits. These aren't deep works of historical scholarship, and don't necessarily attempt to be definitive, but focus on being…
drorzel | June 17, 2013The other big event of the weekend was Commencement at Union. I didn't make it in time for the academic procession and all that, but I did hear John Lewis's speech, which was great. More importantly, though, I was there to see our students graduate, and congratulate them in person.
As I told my thesis student, I'm not always the best about praise and positive reinforcement-- I tend to react to progress in the lab with "That's great. Now, the next thing to do is.." But this year's class was a good bunch of students, and it's been a pleasure to work with them over the last four years.
So,…
drorzel | June 17, 2013This past weekend was more complicated than it might've been. On Friday night, we drove to Whitney Point to my parents' house, then on Sunday morning very early we drove back to Niskayuna so I could make it to Union's graduation on Sunday (I arrived just in time to hear Civil Rights icon John Lewis give the main commencement address, an excellent speech).
The reason for all this driving around was that on Saturday evening, I was inducted into the Whitney Point Central School District Hall of Fame. This is, quite literally, a hall, run ning from the front lobby of the high school to the…
drorzel | June 13, 2013A few months back, I got a call from a writer at a physics magazine, asking for comments on a controversy within AMO physics. I read a bunch of papers, and really didn't quite understand the problem; not so much the issue at stake, but why it was so heated. When I spoke to the writer (I'm going to avoid naming names as much as possible in this post, for obvious reasons; anyone I spoke to who reads this is welcome to self-identify in the comments), he didn't really get it, either, and after kicking it around for a while, it failed to resolve into a story for either of us-- in his case, because…
drorzel | June 12, 2013Hey, dude? Yeah, what's up?
I'm not normally the one who initiates this, but I was wondering: When you were at DAMOP last week, did you see any really neat physics? Oh, sure, tons of stuff. It was a little thinner than some past meetings-- a lot of the Usual Suspects didn't make the trip-- but there were some really good reports from a lot of groups.
Anything really surprising? Well, there was one talk that I really liked a lot, that I went to on a lark, because I didn't understand what the session title could possibly mean, and there was no abstract for the talk: Experimental Studies of…
drorzel | June 11, 2013I saw a bunch of people yesterday tweeting approval of John Hawks's complaint about academic timidity when it comes to blogging:
The bottom line is: People need to decide if they want to be heard, or if they want to be validated. I have long been an associate editor at PLoS ONE, and once I edited a paper that received a lot of critical commentary. That journal has a policy of open comment threads on papers, so I told disgruntled scientists to please write comments. The comments appear right with the article when anybody reads it, they appear immediately without any delay, and they can form a…
drorzel | June 11, 2013As previously noted, I spent most of last week at the 2013 DAMOP meeting, where I listened to a whole bunch of talks. At some point, I was listening to a talk, and said "I bet this guy hasn't given a lot of these before." What was the give-away? The fact that he almost never said "Um."
To the dismay of many students entering science majors, public speaking is a very significant part of being a professional scientist. Scientists are expected to give talks of a variety of different lengths-- 10-15 minute "contributed" talks at big meetings, 25-30 minute "invited" conference talks, 45-60 minute…
