Photos of the Week 2018-02-10

I’m trying to keep up some photographic activity, because I need something to do that isn’t work and doesn’t piss me off. Of course, this means generating lots of images, and I need to do something with them. At the same time, I’m trying to do more personal blogging, so…

This may or may not be sustainable as a weekly series, but we’ll start it out that way, and if it degenerates into an intermittent photo dump, well, so be it.

Snow is exciting!

On Metrics

A history prof from Catholic University named Jerry Z. Muller is flogging a new book titled The Tyranny of Metrics, most recently via an interview at Inside Higher Ed (there’s also a version at the Chronicle of Higher Education, but it’s paywalled, so screw them). This is being hailed in many parts of my social-media universe as being a righteous takedown of the mania for “assessment” in all things.

And, you know, I have some sympathy for this position. A lot of the push for greater “assessment” of everything in academia is pretty useless, just resulting in a lot of silly knees-bent running about. All too often the people calling for more “assessment” of things don’t have any coherent idea of something to do with the quantitative data they generate, they just want to be seen to be generating quantitative data because that’s a Thing that accrediting bodies have decided is important for colleges and universities to be seen to be doing. As someone from a quantitative science, that kind of pointless number-accumulation drives me nuts (and I’ve said so frequently enough that colleagues sigh heavily when the subject comes up in a meeting I’m at, even before I raise my hand to speak…).

That said, I’m not quite ready to sign on with Muller and his anti-metrics campaign, largely because of comments like this (from the IHE interview):

The key components of metric fixation are the belief that it is possible and desirable to replace judgment, acquired by personal experience and talent, with numerical indicators of comparative performance based upon standardized data (metrics)

At a very superficial level, that sounds great, and is very flattering to the faculty ego. We have spent years acquiring subject-matter expertise, after all, and are surely qualified to judge students and others.

On another level, though, this creeps me out. The problem is that an exclusive reliance on “judgment acquired by personal experience and talent” unchecked by reference to standardized data is a wonderful way for decision-making processes to become hopelessly corrupted by individual biases. Many of the most pernicious features of academia have gotten there through the operation of biased personal judgement, stretching back decades, and a lot of efforts to improve academic culture are at their core efforts to unwind those years of biased judgments.

The inclusion of “talent” in that especially gives me pause, because it’s uncomfortably close to the idea that some people are special and succeed for that reason. This is one of the most harmful ideas in all of academia, the source of endless social-media angst, and I’m not at all comfortable with the idea of enshrining it as one of the criteria for who gets to exercise judgment.

This is not to say that any and all quantitative metrics are automatically superior to the judgment of a professional– many of the easy numerical measures we have are, as Muller correctly notes, basically garbage. At the same time, though, we know that they’re garbage because they’re quantitative. People objecting to the use of student course evaluations as a metric for faculty performance rely heavily on the argument that they’re biased against faculty from underrepresented groups. We know because that bias is something that can be quantified, and has in numerous studies.

As crazy as it is to claim that quantitative metrics are inherently objective because they’re quantitative, it’s even crazier to say that relying on individual judgment is the fix for that. And yet, that happens an awful lot when this subject comes up. On a few occasions, I’ve heard this pointed out, and the counter-argument basically amounts to “It’s OK because unlike the quantitative systems we object to, we have the right biases…” I don’t find this to be a great testament to the quality of judgment being employed.

So, on the topic of metrics and assessment and how they’re debated in academia, I find myself deeply conflicted. I’m happy to agree with the claim that many of the “assessment” exercises we currently do are useless, and many of the metrics used in higher education are bad. All too often, though, the anti-metric argument slides directly from “We’re doing a bad job of quantifying this particular thing” to “We should stop trying to quantify anything,” and that’s not something I can sign on to.

It’s ROCKET SCIENCE, People!

I’m normally not a big watcher of rocket launches, but SteelyKid was home sick yesterday, and happened to be bored and demanding right about at the time scheduled for SpaceX’s Falcon Heavy launch, so I pulled up the live feed and we watched it together. It was totally worth it, because when the rocket cleared the tower, she jumped up and down in delight and yelled “It’s launching! It’s ROCKET SCIENCE, people!”

(She also did some heckling of the live chat running next to the streaming video, which was unsurprisingly a bit of a shitshow. Again, mostly worth it to hear SteelyKid talking back to the people who were claiming the whole thing was a fake…)

SteelyKid was super fired up, and decided on a Space theme when picking her clothes for today, so add a tally mark in the “inspiring the youth” column.

While I’m a little jaded about space stuff in general, I have to admit that the simultaneous booster landing was a pretty amazing spectacle. I mean, it’s basically a live-action version of classic sci-fi cover art:

Falcon Heavy boosters landing after the first test launch. Photo from SpaceX Twitter feed.

A lot of people are iffy on the stunt of sending a car into orbit, but I have no problem with that. The most likely alternative is launching a big lump of concrete or some such, so why not have a little fun with it? Some semi-useful collection of simple scientific instruments would’ve been better, sure, but SpaceX is a commercial operation, and they’re entitled to do a little advertising.

Which brings me around to the one thing I did have a problem with, which is the traditional Internet libertarian dunking on NASA any time a commercial space operation does something cool. The passing tweet that sort of crystallized this for me (though I don’t recall the exact source, and don’t care enough to look for it) was something like “Makes you wonder what Boeing and Lockheed and NASA have been doing for the last forty years, doesn’t it?”

And the answer is “Not really,” because I know what they’ve been doing: They’ve been doing what they were paid to do. They spent years doing shuttle launches, and launching satellites, and putting nuclear-powered robot cars on the surface of Mars, where they’ve succeeded better than any of the designers might’ve hoped.

I’m not trying to disparage SpaceX’s achievements, here: they’ve done amazing things, and I’m very impressed. But they’re not remotely in the same business as NASA at this point. They’re doing what they’re doing in large part because Elon Musk is a True Believer who has decided that this is something he’s willing to throw flipping great wodges of cash at to make it happen, and that’s wonderful.

If Boeing or Lockheed or NASA decided that simultaneously landing rockets was a Thing they wanted to spend significant resources on, I have absolutely no doubt that they could make that happen. They haven’t been asked to do that in a consistent way (there have been vague pie-in-the-sky concepts thrown around at various points, but never any sustained effort), and they damn sure haven’t been paid for it, and they’re not in the business of throwing money at causes because they Believe.

And, you know, I totally agree that it would be a more interesting world if they were in that business. Or, better yet, if we as a society were more willing to devote significant resources from tax dollars and the like to developing more awesomely cool rockets and all the many other things NASA does. That’s not where we are, though, and I get a little annoyed with people slagging them off for not doing something that they were never hired for.

That’s especially true when you consider all the things they have been paid to do: all the robot probes visiting Mars and Jupiter and Saturn and Pluto, the Hubble telescope and other orbiting observatories, the GPS system and other practical satellite systems, etc. They’ve focused on the science science side of things, not engineering new rockets, and that was a reasonable decision given the money available to them. It’s also been wonderfully successful, something we shouldn’t lose sight of just because a true-believer billionaire put a car in orbit.

Scientists, Journalists, and Crippling Cynicism

There’s a thread on everybody’s favorite low-stakes conflict, scientists vs. science journalists, going around on social media. It’s from a scientist who moved toward journalism (blogging for the Guardian), and lays out a bunch of reasons why it’s unreasonable for scientists to expect to see a news article article before it gets published. These are mostly pretty good, and founded in research into the content of news stories and institutional press releases.

While the thread as a whole is pretty good, it ends on a sour note for me, with a “get over yourselves” directed at scientists. I find that a puzzling decision, because a slightly different read on the same material would lay the blame for misrepresentation of science on the fact that many journalists are lazy and just lightly re-write press releases. There are plenty of good reasons for more humility on both sides.

The fundamental problem in this conflict, as in so many other stupid petty status fights, is that both sides have an overinflated view of their own work, and an overly cynical view of the other’s. Both sides seem themselves as noble seekers of TRVTH, thwarted by the nefarious actions of the miscreants on the other side.

Scientists in this argument like to portray themselves as ferreting out the secrets of nature, and prize accurate reporting of their work above all else. Any attempt to summarize or simplify their work will inevitably introduce some technical inaccuracies. This is seen as a horrible slight, misrepresenting the purity and elegance of what they do. Thus, the demand to fact-check things before they’re published, and the belief that refusal to allow this indicates an active desire to make them look foolish by inserting errors.

In reality, of course, most of the research carried out by scientists is not remotely important, and only a minuscule fraction of readers will even notice the bits that have been oversimplified. And the value of absolute accuracy tends to be very selective– scientists who fume about tiny errors in stories about their own work are often perfectly fine with gross oversimplifications of whole other fields of science.

But the journalists are not without fault, here. They have a tendency to see themselves as similarly noble in the pursuit of the public interest, ferreting out hidden details and penetrating layers of obfuscation to get to the real, uncomfortable truth. In that view, a scientist or other source asking to check the final story for accuracy is demanding an unconscionable breach of ethics, probably because they have some awful ulterior motive.

In reality, of course, only a tiny fraction of news stories are actually penetrating investigative capital-J Journalism. Most of them are small-r reporting, passing along a minor story that happens to be interesting. The fact that, as shown in the studies described in that Twitter thread, most distortion of science creeps into the news via press materials shows that the field isn’t exactly neck-deep in Edward R. Murrows.

So, yeah, scientists need to get over themselves, and accept that summarization and simplification are a necessary part of communication to a wider audience. Journalists also need to unclench a bit, and recognize that for the vast majority of stories there is not, in fact, any serious ethical concern raised by running a later draft past someone who can check its accuracy.

(There may be logistical issues regarding publication schedules and the like, which is a different conversation. I don’t think that’s an insurmountable obstacle either, but it’s not really the issue here.)

The fundamental problem, here, is a sort of crippling cynicism. Neither side really trusts the motives of the other, and that poisons interactions between them. Each side assumes the other is trying to put something over on them, and the end result is a kind of paralysis.

This sort of thing is extremely widespread in academia, and I find it utterly exhausting. When the starting point for analysis of any proposal or request is “How is this an attempt to screw me?” even trivial matters become enormous stupid fights. This kind of crippling cynicism is pervasive, and it’s responsible for about 2/3rds of the days when I hate my job and fantasize about doing something else for a living (the remaining third comes from grading…).

——

A couple of important caveats: First and foremost, Not All Collective Nouns. While there are too many pseudo-journalists out there lazily re-writing press releases, the best people in the field are very much not doing that. I’ve had very positive interactions with most of the journalists I’ve spoken to about stories they were working on, and I don’t recall feeling badly misrepresented by any of the stories that have quoted me. Similarly, there are a lot of scientists out there who are pleasant and reasonable and easy to work with on this sort of thing (I try to be one– I’ve never asked to review a final draft, and I hope my worst sin in interacting with the media has been losing track of the email asking me for a response).

Both science and journalism are, by and large, well-stocked with good people, and if you give them the benefit of the doubt you likely won’t be disappointed. The conversation tends to be dominated by the worst of the worst, both because they’re personally very obnoxious and because they make wonderfully flammable straw men for the other side to bring up.

I should also note that I write about this from the perspective of a physicist, which is arguably the field of science for which the generally low stakes are at their absolute lowest (our chief competitor being pure math). Most of physics, and especially the stuff I care about, has essentially no partisan political content, so there’s no political reason to misrepresent anything– it’s not like Trump voters are hugely invested in the Copenhagen interpretation while Clinton voters are big Many-Worlds proponents.

(Bernie Sanders is a Bohmian, though. No doubt about it.)

The stakes are higher for fields with partisan political relevance– anything touching on evolution or climate change, basically. Things may feel different in those fields, but even there I suspect that there’s a lot less actual incentive to distort than people think.

But then, I’m a sunny optimist at heart…

Winter Sports Update

At various point over the last few years, I have idly thought that SteelyKid might enjoy skiing, but we’ve had some winters with depressingly little snow recently, and I’ve never really gotten it together to get her out there. My parents were spending the MLK day weekend at Lapland Lake though, and Kate was going to Arisia in Boston, so I jumped at the chance to take the kids up to the fringes of the north country with adult back-up.

I arrived as the kids were getting a ski lesson from Pat, one of the instructors there, who was amazingly good with kids. SteelyKid took right to skiing, as she does almost anything involving physical activity– she’s an amazingly good natural athlete, which is a continual source of puzzlement for me and Kate. Neither of us ever had anything close to SteelyKid’s sense of balance and ability to pick up the moves for some new sport or game. The Pip had a harder time with it, which the instructors later commented may have had something to do with a bad set of ski boots.

Anyway, after a near-catastrophe when I accidentally took SteelyKid on a trail with a way-too-big hill on it, she was all about the skiing, playing broomball on skis in the “Reindeer Rally” that afternoon, and the next morning she dragged me and my dad out bright and early to ski a mile or so out to the lake (seen in the “featured image” above, and repeated below) and back. I shot this on the way back:

This was the third time she’d ever put skis on. Like I said, she took right to it… I was on skis for the first time in at least 25 years, and thus somewhat less graceful than she was, but it was a good deal of fun.

The Pip wasn’t as fired up about skiing as his big sister, though he did do a couple of lessons. He had a grand time on the tubing hill, trying to see how close he could come to riding his plastic sled into the creek (which wasn’t terrifying at all, nope). He was also quite content to lounge around the cabin and read books:

(The specific book he’s reading in that shot is The Stone Heart by Faith Erin Hicks (which is excellent, by the way). This was one of SteelyKid’s Christmas presents, but the Little Dude has gotten all fired up about reading, and powered through both volumes of the series that weekend.)

Anyway, it was a really good time, and SteelyKid has been occasionally agitating to go back. They got a few inches of fresh snow this week, so we’re going to make the run up there for the afternoon, and see how that goes…

Today in “AMO Physics Is Way More Pleasant Than Biology”

As part of my “blog more regularly” push, I’m going to start moving some things that I’ve been posting as Twitter threads over here, where they’ll maybe be more pleasant to read for the tiny number of people who bother to read them. Starting with this Ed Yong piece at The Atlantic on a couple of life-science journals making it easier to publish papers whose main results were “scooped” by another group within a few months.

This is very much a Good Thing, but also a bit of a head-scratcher for me, particularly the quote from journal editor Eve Marder saying “We are seeing a trend toward the co-submission of papers from labs that choose not to compete but, rather, to jointly announce new findings.” Thee are both things that have been reasonably common in my corner of physics, going back twenty-plus years.

I mean, two of the papers I published in grad school had technically been “scooped” in this way– our paper on optical control of collisions came out a couple of months after a similar paper from a Japanese group, as was the paper on collisions in optical lattices. In both cases, the Japanese group sent us advance notice of their work, and offered to delay publication slightly so the papers could come out together. We didn’t take them up on that, but in both cases, our paper came out later in the same journal, Physical Review Letters, which was about as high in the prestige hierarchy as it could plausibly get.

It’s not just us, either– when I was doing the research for the ebook on quantum simulation that I wrote for Physics World (which is a free download, you should read it), I saw a bunch of this. Papers announcing key advances in the techniques used for these experiments tend to come in groups: there are 2-3 papers demonstrating single-atom resolution in optical lattices with bosons, then 2-3 papers doing the same thing with fermions, etc. These come from different groups, but they’re all in glamour journals (granted, not exactly the same journal– typically one is in Science and the next in Nature, or vice versa). There doesn’t seem to be any career-destroying penalty to being second in these sort of races in the world of cold-atom physics.

Now, granted, in these groupings, the two papers tend to have slightly different angles on the same thing, but that’s a natural part of doing science– different labs think about the same problem in slightly different ways, so the results from two groups are never perfectly identical. But my experience within my home research community has not been that second-place papers are totally blocked from publication, or even blocked from publication in the top journals. There are plenty of examples of pairs or triplets of papers that report essentially the same physics result within a few months of each other, all in top-tier journals.

So, I find the story from biology slightly surprising. It’s a positive development, but also a bit of a “thank God I don’t work with these people…” kind of thing. I’m making another tally mark in the column headed “Life Scientists Are Assholes,” and then partially erasing it.

Academic Book Chapter: Pseudoscience

One of the many things I’ve been busy with that have kept me from blogging has now seen print: a chapter in the new MIT Press book Pseudoscience: The Conspiracy Against Science, edited by Allison Kaufman and James Kaufman. This has a bunch of different takes on pseudoscience, from a range of academic disciplines, and includes Internet luminaries Orac and Ivan Oransky.

My chapter is titled “Scientific Failure as a Public Good: Illustrating the Process of Science and Its Contrast with Pseudoscience,” and the argument is pretty similar to this 2015 piece for The Conversation (which is, in fact, how I got asked to write the chapter in the first place…). I go through two big recent debacles in physics, the OPERA faster-than-light neutrino thing and the BICEP2 primordial gravitational waves business, and point out how the behavior of the scientists involved fits a clear pattern showing how real science works. Both the initial claim and the criticism of it come from within the relevant scientific community, the debate over the validity is carried out in the regular scientific literature, and the ultimate resolution comes with the active participation of the original scientists.

As a contrast to this, I look at a specific example of a pseudo-scientific enterprise, namely the “hydrino” physics of Randell Mills, a fringe theory which is promoted by an outsider, mostly operates through non-standard channels, and barely acknowledges the existence of criticism, let alone accepting it and working to resolve the issues. The contrast is really stark, and I would say that this sort of procedural distinction can be a useful part of a bullshit filter for anyone looking to distinguish real-but-incorrect science from pseudoscience.

This is written for an academic audience, so the language is a little more formal and complicated than a lot of my popular stuff, which made an interesting contrast during the writing process. It also involved a lot of LexisNexis searching for news articles, which was kind of fun in a really dorky way. Other than the occasional baroque sentence, though, it’s probably a pretty accessible read, since the editors are psychologists, not physicists.

Or, at least, it would be accessible to read if it were, you know, accessible. That part of academia hasn’t really embraced the concept of the arxiv yet, so there isn’t a readily available online version. I think there’s some provision for posting a PDF on my website eventually; I need to check into that.

The finished book looks pretty spiffy, though:

My author copy of Pseudoscience: The Conspiracy Against Science, now out from MIT Press

I can’t vouch for any of the other pieces (yet, anyway; I may try reading a few), so I don’t know that I’d push you to drop $40 on a copy for yourself. You could ask your local library to pick it up, though…

Charlie Pupdate

Yesterday’s post launching the blog portion of this site included some cute-kid photos, but of course they’re not the only photogenic mammals in Chateau Steelypips any more. There’s also Charlie the pupper, shown here in a collage helpfully assembled by Google Photos:

Collage of Charlie the pupper photos, put together by Google Photos.

(Google Photos has recently added Charlie to the list of “People and Pets” that it automatically recognizes in pictures. I, for one, welcome our new image-recognition-algorithm overlords…)

Charlie is, as he will constantly remind you, a good boy, really sweet and enthusiastic with people and other dogs. He’s been invaluable for schoolday mornings, because when it’s time to get the sillyheads up for school, he goes charging up the stairs and licks their hands and faces (he especially loves to lick The Pip’s face, possibly because the Little Dude derives roughly 25% of his calories from bacon) while they’re in bed. The ambient morning stress level is about 30% lower with Charlie on the job. (That’s 70% of a rather large baseline, alas, because SteelyKid is emphatically Not A Morning Person…)

There are, of course, a number of adjustments that come with getting a new pupper after a couple of dog-less years. Charlie’s energy level is, um, juussssst a bit higher than Emmy’s was during her last few years, which means longer and faster walks than I had become accustomed to. Also a lot more “Jesus, what is he chewing on NOW?” moments when we’re all around the house. We’ve had to become vigilant about keeping the downstairs bathroom door closed, because otherwise when he gets bored (say, because somebody stopped petting him for thirty seconds), Charlie will trot off and come back to present us with a slightly slobbered-on hand towel.

One of the biggest adjustments has been that he’s really good with other dogs– he’s got a lot of puppy enthusiasm for roughhousing, but manages to take the hint from dogs who aren’t into that style of play, too. Emmy was Not Good with other dogs, so we always had a pet-sitter when we left town, and I had a whole set of routines for our walks designed to avoid encountering other dogs. Charlie, on the other hand, loves being taken to the dog park; the more dogs there, the better.

Panorama of the Niskayuna dog park stitched together from two shots tracking Charlie as he ran by, leading to a double pupper image.

It’s been a lot of fun taking him over there, and getting to experience the social aspects of dog behavior as well as the human-oriented stuff we had with Emmy. We can also leave him with a boarder when we go out of town, and he makes regular visits to the groomer for a bath and a day of playing with their day-care dogs. The only hitch is that he HATES riding in the car, and needs to be physically carried to the minivan and stuffed inside, even when we’re going someplace fun.

Pretty much everyone who meets him exclaims over his coloring, and also what a good boy he is for a nine-month-old puppy. This of course makes me feel proud, which is really weird because we have very little to do with that– he was very well socialized by his foster family before we got him, and naturally has a good temperament. And yet, the immediate reaction is the same as when somebody praises one of the kids, with whom I share actual genes…

Anyway, that’s the current status of Charlie the pupper, who is well settled into Chateau Steelypips and much loved by all, and especially by the kids. Both of them take almost any opportunity to play with him, which he is of course happy to indulge.

Is This Thing On?

Since the shutdown of ScienceBlogs, I’ve been feeling the lack of a personal blog a bit. It doesn’t seem quite right to add to the now-archived Uncertain Principles, though– that era is over– and the thought of adding yet another WordPress install to all the ones I already have is kind of exhausting. I’ve got this site right here, though, and it’s a blog system, after all, so let’s see how it works to put a “Blog” category in with the rest, and start posting some stuff here.

Of course, the most important rule of public writing is that you have to give the people what they want. So here are some cute kid photos. First, The Pip looking pleased with himself:

And then SteelyKid in profile:

I’m not sure how regularly I’ll be posting here, but just having the option again will be nice.
