The Core Ideas of Science

/ 24 Comments

A National Academy of Sciences panel, chaired by Helen Quinn, has released a new report that seeks to identify “the key scientific practices, concepts and ideas that all students should learn by the time they complete high school.” An ambitious undertaking, but a sensible one. At the very least, efforts like this serve to focus attention on what’s important across a wide variety of K-12 curricula, and at best it could help prod schools (or states, really) across the country into teaching more coherent and useful science to kids. Here’s the web page for the report, a summary (pdf), and the report itself (pdf, free after you register).

So what are the core ideas of science? They are all listed in the summary report, and divided into three categories. The first category is “Scientific and Engineering Practices,” and includes such laudable concepts as ” Analyzing and interpreting data.” The second category is “Crosscutting Concepts That Have Common Application Across Fields,” by which they mean things like “Scale, proportion, and quantity” or ” Stability and change.” It’s great that the organizational scheme emphasizes ideas that stretch across disciplinary boundaries, but there is definitely a danger that the resulting items come off as a bit vague. The secret to success here will be how they can be implemented, with concrete examples.

The third category is the nitty-gritty, “Core Ideas in Four Disciplinary Areas,” namely “Physical Sciences,” “Life Sciences,” “Earth and Space Sciences,” and “Engineering, Technology, and the Applications of Science.” (Math is not within the report’s purview.) And here are the actual core ideas proposed for the physical sciences: …

Unsolicited Advice: Non-Academic Careers

/ 10 Comments

Since I know nothing very useful about the job market outside academia, I solicited suggestions for specific pointers and helpful websites. A bushel of useful advice and thought-provoking comments resulted.

My original idea was to summarize what I thought was the best advice, and turn it into a single post. This idea has been undermined by (1) me not knowing which advice is best, and (2) a wide variety of occasionally-contradictory advice, presumably all applicable in different circumstances.

So instead here I’m just going to link to some of the most promising-looking resources that were mentioned. I encourage you to read the comments on the original post to get more ideas, and chime in here to keep the conversation going.

Soliciting Advice: Non-Academic Careers for Ph.D.’s

/ 70 Comments

While the previous post bemoans the lack of simple world-changing ways to make the career path for aspiring academics more pleasant (other than bushels of money falling from the sky, of which I would approve), there is one feasible thing that everyone agrees would be good: better career counseling for Ph.D. students, both on the realistic prospects for advancement within academia, and concerning opportunities outside.

I always try to be honest with my own students about the prospects for ultimately landing a faculty job. But like most faculty members, I’m not that much help when it comes to outside opportunities, having spent practically all my life within academia. I’m happy to give advice, but you’d be crazy to take it, since I have no idea what I am talking about.

But that’s a correctable state of affairs. So: I’m hereby soliciting good, specific career advice and/or resources for students who are on the track to get a Ph.D. (or already have one) and are interested in pursuing non-academic jobs. This might be particular jobs that are Ph.D.-friendly, or websites with good information, or relevant fellowships or employment agencies, or just pointers to other resources. (For example: do you know the difference between a CV and a resume?) The more specific the better, and including useful links is best of all. General griping and expressions of bitterness should be kept in the previous thread; let’s try to be productive. And there’s no reason to limit it to physics, all fields are welcome. Advice that is useful for only a tiny number of people, but extremely useful for them, is certainly sought. We’re looking for things that have a nontrivial chance of actually helping some specific person at a future date.

Most of all it would be great to have input from people who actually got a Ph.D. and then went on to do something else. But it’s the internet, everyone can chime in.

I will take what look like the most helpful suggestions and collate them into a separate post. Spread the word, let’s get as much input from different sectors as we can.

Toward More Comfortable Bottlenecks

/ 81 Comments

Jessica at Bioephemera posts a provocative quote about the way we train and employ young people who are seeking careers in academia:

They’re doing exactly what we always complain our brightest students don’t do: eschewing the easy bucks of Wall Street, consulting or corporate law to pursue their ideals and be of service to society. Academia may once have been a cushy gig, but now we’re talking about highly talented young people who are willing to spend their 20s living on subsistence wages when they could be getting rich (and their friends are getting rich), simply because they believe in knowledge, ideas, inquiry; in teaching, in following their passion. To leave more than half of them holding the bag at the end of it all, over 30 and having to scrounge for a new career, is a human tragedy.

— William Deresiewicz, The Nation

The author goes on to bemoan this “colossal waste of human capital” — all those talented young people spending time getting Ph.D.’s, then not eventually landing faculty jobs, when they could be going right into productive careers in some other field.

I’m sincerely unsure what to think about the occasional complaints one hears along these lines. On the one hand, I firmly believe that the grad school/postdoc/junior faculty years should be enjoyable ones, not days of peril and gloom living under a cloud of uncertainty. If there were a way to make the journey easier, I would be all for it. I can think of small ways to do so, and am certainly in favor of such incremental improvements.

But on the other hand, I really can’t think of any sensible major improvements, for a simple reason: there are many people who would like to be academics, and few available jobs. Short of multiplying the number of college professorships by a factor of three or so, I’m not sure how to address the primary cause of this anxiety — the difficulty in getting jobs. If you knew you were going to land a tenured spot at a good place, it would be much easier to bear the indignities of grad-student/postdoc level salaries for a few years. Deresiewicz says, “If we don’t make things better for the people entering academia, no one’s going to want to do it anymore.” But if that were true, why are there so many “highly talented young people who are willing to spend their 20s living on subsistence wages when they could be getting rich”? These seem to be contradictory worries.

Obviously one thing to do would be to dramatically cut down on the number of people who get into graduate school. But that just moves the bottleneck around, it doesn’t change its overall size. And I don’t want to be the one who says to a somewhat-promising-but-not-superstar-quality grad school applicant, “Sorry, I’d enjoy working with you, but we’ve decided not to admit you because in our judgement your chances of eventually getting a faculty job aren’t quite as good as some of our other applicants. So you see, it’s for your own good.” Generally the people who advocate this kind of strategy are the ones who have already been admitted to grad school. (If you’re waiting for Deresiewicz’s solution, here it is: “The answer is to hire more professors.” Well, okay then.)

Again, I honestly don’t know what should be done. I would love to improve the lifestyle and general well-being of students and postdocs in any feasible way. Not sure what that way would be.

Open Science

[Note: this post was published prematurely, then deleted, and is now back.]

Michael Nielsen gave a great talk at TEDxWaterloo about the idea of “open science”:

Open science: Michael Nielsen at TEDxWaterloo

There’s a great deal of buzz about “openness” in certain sectors of the science community; largely this has passed physics and astronomy by, because we’re already pretty darn open. It’s hard to image something more open than arxiv, where everyone puts their papers up for free even before they’re published in a journal.

But Michael’s talking about something much more ambitious: opening the process of creating science, not just publishing it. For experimentalists this would be difficult, for obvious reasons. (You think people who sweat to build an experiment are going to invite the public in to take a whirl?) For theory it is also hard, but the reasons are more subtle.

The point is that credit in science is given out on the basis of getting your name on published papers. In the arxiv era, the papers don’t necessarily have to appear in a traditional journal — but that’s a topic for another day. The model is set in stone: you have an idea, you work out its consequences to the point where it’s publishable, and you write a paper. Without that last step, you’re not going to get any credit. (Very occasionally you will see references to “unpublished work” or “private communication,” but it’s rare and not really for big-ticket ideas.)

So if I had an idea, I would either work it out myself or start working with students or collaborators. I certainly would not go around publicizing an undeveloped idea; I wouldn’t get any credit for it, and someone else could take it and develop it themselves. I might give seminars in which I mention the idea, but that’s only recommended once it’s to the point where a paper is on the horizon.

Michael and others want to overthrow that model. Their shining example is this blog post by Tim Gowers. Gowers is a mathematician who proposed attacking an open math problem right there on his blog, by asking for comments from the crowd. If they succeeded, they could publish a paper under a collective pseudonym. He next chose a problem — developing a combinatorial approach to the Hales-Jewett theorem — and, several hundred comments later, announced that they had succeeded. Here’s the paper. Buoyed by this success, people have set up a Polymath Wiki to expedite tackling other problems in this way.

Could this work for theoretical physics? I don’t see why not. But note that Michael spends a lot of his time in the talk pointing out the obvious — crowdsourcing doesn’t always work. I could easily imagine ways in which such a project could fail; too much noise and not enough signal, everyone with good ideas deciding they would rather work on them by themselves rather than sharing openly, etc.

Might be worth a shot, though. I’m thinking of suggesting some ideas here on this blog and seeing whether we get any useful input. Let me sleep on it.

It’s hard to have a clear-eyed discussion about academic jobs and tenure, both because emotions and stakes are very high and because everyone (including me) tends to universalize their personal experience. So let me just jot down some closing thoughts in the interest of clarity.

As Julianne says, there is a worry that passionate young scientists who read about how hard it is to get jobs or tenure will be dissuaded from even trying. I certainly appreciate that, and wouldn’t want to be responsible for scaring anyone away from this job I love so much myself. On the other hand, there is a countervailing worry: that in our attempts to convey our own enthusiasm for this career, we will be insufficiently honest about the difficult challenges it entails. I want to be as clear and open as possible about both the joys and the hurdles, and leave it up to responsible individuals to make their own choices. Of course there are many people who happily violate various of the guidelines I suggested, and nevertheless have no trouble getting tenure. It’s the underlying of the guidelines, not any of the individual points, that I would rather have explicit than hidden.

I sometimes hear people complain that senior scientists paint a rosy picture to lure unsuspecting students into their labs, shielding them from the harsh realities of the job market, just to squeeze a few years of indentured servitude out of them before they are blindsided by the realities of the academic career path. Most such griping, I figure, has to be some kind of defense mechanism; I certainly know that when I was in grad school we were all completely aware of what the job market was really like, and talked about it all the time. I make sure to talk openly about it with prospective students, and with students who want to have me as their advisor. But my sense is that there is not as much open talk about the tenure process, so I thought I could add some perspective. My guidelines were quite purposefully stark, to balance some of the vagueness that often characterizes the topic. As long as the institution of tenure exists, some people will be denied it, which is inevitable; what is not fine is if people are legitimately surprised when it happens. That should never occur.

It shouldn’t come as news that getting tenure at a top place requires a certain amount of focus and dedication to the task at hand. It’s not nearly as bad as, say, a concert violinist or an olympic gymnast. Only a very few people get to have these highly sought-after jobs, and it will naturally be beneficial to try as hard as you can if you want to be one of them. My purpose in the blog post was to emphasize what form that trying should take if that is your goal, not to frighten people with how hard it is.

How To Get Tenure at a Major Research University

/ 78 Comments

[Update: added a couple of useful points.]

This is the time of year when prospective graduate students are visiting different universities, deciding where they will spend the most formative years of their scientific lives. Amidst the enthusiastic sales pitches, I try to make sure to remind everyone that the odds of success are long — there is a bottleneck that shrinks as you go from grad school to postdoc to junior faculty to tenure. Probably the biggest hurdle is the leap from postdoc to junior faculty; it’s easier to get tenure once you’re a professor (statistically speaking) than to become a professor in the first place.

But it’s not guaranteed! As many of you know, I was denied tenure myself. This actually puts me in a pretty strong position to talk about the ins and outs of what it takes to succeed, having seen lack-of-success (is there a word for that?) up close and personal. I’ve avoided talking too much about this topic, partly because armchair psychologists have trouble resisting the temptation to take anything general I would say and attempting to match it to specific people and aspects in my own case, despite a pretty thorough lack of familiarity with the facts. On the other hand, maybe I can offer some actually useful guidance to people who are trying to do something difficult and important for their future lives.

So here goes: how to get tenure. But first, caveats. My own experience from grad school on has been at top research places, so those are the only ones I can speak usefully about; the situation will generally be very different at places that put more of an emphasis on teaching, for example. So really I’m talking about places that think of themselves as being in the top 10 or so in their research fields. And of course, to every set of rules there are exceptions; it’s not hard to find people who violated one or more of these guidelines, so don’t take them as written in stone. Every case, and every department, is different. Finally, don’t think of these as too bitter or cynical; I’m simply trying to be honest, with perhaps a small slant to counteract some of the misinformation that is out there. (This misinformation doesn’t usually arise from willful lying, but from the slightly schizophrenic nature of the mission of research universities; see The Purpose of Harvard is Not to Educate People.) I’m generally in favor of the tenure system; like democracy, it’s the worst system out there, except for all the other ones that have ever been invented.

With all that throat-clearing out of the way, let’s get down to brass tacks. Here is the Overriding Principle: what major research universities care about is research. That’s all. Nothing else. But even once you recognize that, there is still some craft involved in shaping your research career in the right way. This isn’t the place for me to pass judgment on this principle; I’m just elucidating its consequences. This is a how-to manual for the real world, not a roadmap for Utopia.

You’ll be pleased to learn that there are actually two different routes to getting tenure, so you can choose which one works better for you. The first one is simple to describe, and comes down to a single suggestion:

  • Be a productive genius. This deserves to be classified as a separate technique because, for the small number of easily-recognized true geniuses out there, the rest of the suggestions below are beside the point. Do whatever else you like, as long as you are revolutionizing the field on a regular basis. It’s worth stressing the word “productive,” though. The trash heap of history is littered with geniuses who thought it was beneath their dignity to actually produce anything; that won’t fly, generally speaking, in this game. So if the genius thing is working out for you, great; just be sure to put it to productive use, and you’ll be fine.

The rest of us schlubs, on the other hand, need a more explicit checklist. So here’s what ordinary people should try to do if they have a junior faculty job at a major research university, and would like to get tenure. …

Email Addresses

/ 24 Comments

On the one hand, it’s extremely convenient for young academically-oriented people to grab an email account with Gmail or some other generic provider. The nature of the profession is that you will jump around from institution to institution — grad school, postdocs, faculty positions — and it’s extraordinarily annoying to have to keep switching email addresses with every move. Changing jobs is hassle enough as it is.

On the other hand — it’s letter-of-recommendation season, and there are still some backwards institutions out there who refuse to accept letters submitted from non-academic email addresses. Grrr. Get with the program, people!

Okay, not every blog post will be deep.

Update: prodded by Anil in comments, I verified that indeed Gmail is smart enough to let you use Gmail to send from any other email address you have. Just go to “Settings,” then “Accounts and Import,” then “Send Mail As.” Obviously you can’t use just any address, only ones you can verify. Hooray for Gmail!

No One Is Spared!

/ 23 Comments

Caltech had its commencement ceremony last Friday, and I donned a cap and gown to march up on stage with the other faculty members. It’s always a great day, as years of work comes to fruition for several hundred students, ready to move on to the next stage of their careers.

Naturally, there was singing. The Glee Club sent spirits soaring with the Caltech alma mater, “Hail CIT.”

In southern California with grace and splendor bound,
Where the lofty mountain peaks look out to lands beyond,
Proudly stands our alma mater, glorious to see.
We raise our voices proudly, hailing, hailing thee.
Echos ringing while we’re singing, over land and sea.
The hall of fame resound thy name, noble CIT.

The one that got my attention, however, was the other song — Gaudeamus Igitur, apparently a “traditional college song.” How have I spent so many years in academia without coming across this one? It was sung in Latin, but a helpful translation into English was provided.

Therefore let us rejoice
While we are young
After pleasant youth,
After troublesome old age,
The earth will have us.

Where are they who before us
Were in the world?
You can cross the heavens,
You can go to hell,
If you wish to see them.

Our life is brief,
Shortly it will end.
Death comes quickly,
It snatches us cruelly,
No one is spared.

Long live the academy!
Long live the professors!
Long live each student!
Long live all students!
May they always flourish!

Cheerful, no? We’re all going to die, but at least the university will live on. Comforting.

And now Wikipedia informs me that a few verses were apparently left out of our version. To wit:

Long live all girls
Easy and beautiful!
Long live mature women also,
Tender and lovable
Good [and] productive,

Long live the state as well
And he who rules it!
Long live our city
[And] the charity of benefactors
Which protects us here!

Let sadness perish!
Let haters perish!
Let the devil perish!
Let whoever is anti-student
As well as the mockers!

So they left out the bits that were veering uncomfortably close to sexism, fascism, and serial killer-ism. I’m thinking they didn’t want the ceremony to drag on for too long.

Congratulations to Heywood and Moira!

/ 5 Comments

It’s that time of year again. Young graduate students, having toiled for several years at the feet of Science, are kicked out of the nest to take their places among the ancient and honorable community of scholars. If you will forgive the mixed metaphors.

This week we had a double-decker celebration: both Heywood Tam and Moira Gresham successfully defended their Ph.D. theses. Congratulations to both!

Heywood was stuck with me as an advisor, but he seems to have turned out okay. We worked together on a number of papers that looked into models of Lorentz violation, including issues of extra dimensions and stability. More recently we’ve been finishing a couple of papers on fine-tuning in the early universe — coming soon to a preprint server near you! In the Fall Heywood will leave the dry heat of SoCal for the damp heat of Florida.

Moira’s advisor was Mark Wise, but we also interacted quite a bit. She and I collaborated with Heywood and Tim Dulaney on a couple of aether papers, and she and Tim recently wrote a really interesting paper on anisotropic inflation. But she promises that her next project will be completely Lorentz-invariant. And she’ll be doing it from Ann Arbor, where she’ll be joining the Michigan physics department as a member of the Society of Fellows.

Always bittersweet when students graduate; it will be a loss to Caltech when the leave, but it’s great to see people launch their independent research careers. Best of luck to both Moira and Heywood!
