Angry Physics

Breaking News

2013-01-05T16:19:00.000-08:00

I know that I'm everyone's source for late-breaking physics-news, and so I've rushed to the terminal (neh, laptop) to update you all.

Everyone's favorite Star Trek-related author and physicist Lawrence Krauss is talking about The Higgs Boson Hangover. It's pretty mild compared to what Peter Woit might say, but then again this is in Slate and probably reaches a wider audience. The older I get, the more I realize that I continually overestimate the understanding of science and how it proceeds by the general public. And so it's good to publicize that scientists tend to want to be surprised instead of proven right.

Doug is discussing some fraud in the biomedical community about which I was completely unaware. This is, of course, part-in-parcel of how science corrects itself. Teaching the scientific method in school is all well-and-good, but I think it would behoove us to teach how science-the-enterprise corrects for the faults of those who practice it.

Slashdot today mentions a Forbes article about how I've got such a low-stress job. The link isn't working for me and so I've not read it, but apparently there's a big stink about it, and Slashdot has a number of links to some arguments against.

Finally, unrelated to physics, I wanted to link to a couple pieces by, and with, the person who turned-in Bradley Manning for allegedly leaking all those documents to Wikileaks: a very difficult piece by Adrian Lamo and a chat with him and someone else. Whatever one thinks of Manning's actions, the torture he's been put-through is awful and inexcusable.

This is a long read, but I found it pretty interesting. A guy who abandoned his goal of entering the academic linguistics world, but still had the drive to contribute bycreating a new language. But at one point he's quoted as:

I was surrounded by all these people hanging on my every word. It was intoxicating-especially for a loner like me. For one day, I got to play as an academic. I got to live this fantasy where I took the other path in the garden. I got to see what it would have been like if I had gone to graduate school and become a professional linguist. The fates of the universe tore open a window to show me what my life could have been. That night, I went back to my room, took a shower, and burst into tears.

Umm, where are these people hanging on to my every word? Am I doing this wrong?

Naughty, Naughty Boy

2012-12-11T17:38:00.000-08:00

This guy's no physicist (but did major in math as an undergrad), but he is an academic who got in trouble with financial reimbursements from his University: Sudhir Venkatesh, a sociologist at Columbia of whom you may have heard via the best-seller Freakonomics which features his work prominently.

This type of financial ''discrepancy'' doesn't seem terribly uncommon, but I don't see how this happens as much as it seems, given how tight and controlled most university's systems are. It's probably just that my mind isn't built to see the ways to abuse the system (that's not supposed to sound as immodest as it does).

His story and rise to academic stardom though is quite emblematic of how the academic world deviates from a pure meritocracy. Not to take anything away from the guy, but he clearly knows how to work the system and it's hard to believe there aren't many others who have gained far less with work just as significant.

A bit more can be found at the Freakonomics blog.

2012-12-04T08:51:00.003-08:00

I've had a number of things to share over the past few months, but none significant enough to merit a blog posting (as if that were a high hurdle!). It even crossed my mind for the first time that Twitter might be appropriate for communication.

My physics life, as opposed to family/friends/etc, has been up-and-down recently. I was riding high, feeling confident for a while...invitations to talk or visit, emails about recent papers, new projects with interesting collaborators, a phone interview with an interesting university.

Now, not so much. No response to my latest from some folks interested in a paper. Not even a "thank you but..." from the search committee. One collaborator has gone completely AWOL, hopefully just because he's too busy. A big snafu with some refereeing has left me pissed at some editors. A bunch of grant proposals are submitted, but given the current financial situation (e.g. "fiscal cliff") facing the U.S. right now, it's hard to be optimistic.

I know things go up and down and I've got enough experience and job security to ride it out. But it's not fun.

Introversion

2012-04-27T20:16:00.003-07:00

Chad links to this piece at the CHE, from which I quote:

But academe is a profession of opposites. Long periods of social isolation—research and writing—are punctuated by brief periods of intense social engagement: job interviews, teaching, conferences, and meetings. One reason that completion rates for graduate programs are so low—and unhappiness levels so high—is, I suspect, because students are not selected for the full range of aptitudes they will need to be successful in graduate school. And there are few if any supports in place for those students who struggle with the extremes of introversion and extroversion that academe demands.

I've often mentioned to students that being outgoing and social is a huge asset in academe, and I often get confusion. People don't think of physicists as social or outgoing. I've long struggled with these aspects, though not as much as some. I'm easily in the introverted category, but I don't obviously lack social skills (those who know me well often laugh at my lapses, but among physicists I can blend it rather well). In any case, I never quite thought of it as above...as a contrast. But of course it is. Even in the comfort of one's own institution, there are encounters with colleagues, students, etc. These are generally pretty manageable...if I feel overwhelmed, I can always retreat to my office with a closed door. However, one day during a vacation, I had to run into the office to get something. While walking across an empty campus, a woman walks towards me whom I completely ignore, until, up close, she says "hi." I look up, completely baffled and mute. It must have been fifteen seconds till my mind could bring up my database and realize I knew her. But it was too late. Unsure of what to do, not wanting to insult her, I emailed her saying I was spaced out and didn't mean to ignore her. More accurately I just wasn't prepared. I imagine an extrovert simply doesn't need to mentally prepare for an encounter. They naturally make the most of such an encounter. But seconds matter and one can get better at this stuff. It takes more than reading tips in blogs. It takes practice.

Everyday physics questions

2012-04-22T15:00:00.000-07:00

Some of these are better than others. Feel free to discuss in the comments. I doubt I'll post my answers unless some sort of argument breaks out. At best, these might be interesting, and at worst, they should give non-physicists some idea of what's going through the physicists head when the conversation turns boring:

when one goes to return the shampoo bottle to its place, its moment of inertia is generally much larger than when you picked it up. The moment of inertia is essentially a measure of a rigid body's resistance to rotation, and therefore one might naively think it would be more stable after use. However, that's clearly not the case. So the first question is why? The second is: is there some limit in which the increase to the moment of inertia would be the dominant effect so that one could construct a shampoo bottle that is unconditionally stable about its bottom?
Walking down the street, one observes someone who is otherwise well covered and obscured by clothing, but who has some cleavage apparent. As this person walks towards you, you observe the limited cleavage heaving up and down a bit. The question is: can one legitimately estimate the endowment by the time-scale of the heaving or instead does one just instinctively increase ones estimate (given there's so little else to go on) simply because there is motion at all? In other words, are the variables too many...speed, type of walking motion, type of support clothing etc...to provide any real estimate? [Sorry for the crassness...]
Seeing a Smart car, I am struck by the fact that it is so small but yet the fuel economy isn't particular good, compared to other micro-cars. If one considers good economy cars and then considers mopeds, the fuel economy roughly increases by a factor of two. What is the ultimate (ie physical) limit of fuel economy? Clearly certain assumptions have to go into such a limit, but how many?

Refereeing...

2012-03-25T19:35:00.000-07:00

So I've got this paper to referee, this horribly written mess. Among its author list are esteemed people I know who clearly didn't even read the full text. It's a silly paper just to pad the CVs of some listed. I know I'm supposed to just sign-off on it, but I can't. I know I'm supposed to point out the most atrocious of the comments and be done with things. Indeed I've already gone through and mentioned most of them. But now I'm thinking of deleting them all and telling the editors that they should publish as is! Right away! Maybe with footnotes next to the most ridiculous stuff saying explicitly that all the authors agree on these points. What do you think?

In any case, I just worry a bit about anonymity...the editors know who is doing the refereeing, and the editors can be pretty chummy with certain folks. Indeed, when one does email reviews of NSF proposals, the panel *sees* who wrote the review! Maybe something similar happens here...someone on the editorial board finds out, and lets the authors know how obnoxious and insulting I was to these people.

But here's the kicker...I'm pissed off that I've probably spent more time "editing" this paper than some of the established authors!

AGW

2012-03-02T18:45:00.000-08:00

I'm somewhat sympathetic to those reluctant to accept anthropogenic global warming (AGW). Indeed, it seems that for many their reluctance is in large part a reaction to the force with which "they" try to force it on people. So instead of trying to argue the science, let me try respond gently to certain fair, but likely misguided points, that some of these "deniers" make:

they don't reject science, but instead choose which scientists to accept: I think what many people fail to realize is that one can find scientists who say the craziest things. Even Nobel-winning physicists have some crazy ideas. Sure, science isn't a democracy, but when just a small minority of scientists take a certain opinion, the odds are against their being correct. And so one could choose to accept that relativity is wrong, that the mechanics even of the very small is truly deterministic, that evolution is wrong, that the big bang never happened. Heck, moving beyond science, one could choose to believe those who are sure mankind never visited the moon, that six million people didn't die in the Holocaust, etc.
climate scientists are motivated to scare the public to maintain their jobs: Ok, fair enough. But aren't we all motivated out of self-preservation? However, it wouldn't occur to me to publish something I didn't think was true for some professional gain. Besides the dishonesty, I would fear the inevitable refutation by other scientists. Academic scientists are no saints, but I think it fair to say that the motivations are more likely to have them steal the ideas and credit of others rather than to attempt to steer a research program along some particular agenda. And could they even pull such a global conspiracy off? But even if you dispute this, surely one so misanthropically inclined would have even greater suspicion of the intents and effectiveness of huge multi-national companies supporting the denier community.
there are many instances of mistakes or disputed claims. The science is either wrong or not well established: Deniers have often referred me to read the denier blogs. However, what these blogs generally have are fine-scale critiques of certain small claims, but with titles suggesting a larger scale of the critiques. I think what many scientists are good at is reading a paper and assessing weakness and strengths. Just because there may be some valid criticism of some aspect of some certain research, that's not necessarily an indictment of the entire field. Right now, I'm trying to figure out how critical to be in my paper which basically says that a competitor is wrong. But at the same time, the competitor is wrong in degree because he's over simplifying. As such, his overall position isn't even as "wrong" as the deniers claim about AGW. This isn't a court of justice with a final verdict. It's a messy, complicated system that we need to understand.

It's hard out here for a physicist

2012-01-17T19:26:00.000-08:00

"Trying to write a pseudonymous blog that wouldn't be immediately identifiable as me would require an awful lot of effort, more effort than would be worth it for the sake of blowing off a little steam."
Chad Orzel

So true, so true. It's darn hard. And what are the rewards? I get
no credit, no acclaim. Heck, I hardly get any readers. It all started
with my reviews. I actually take reviewing seriously which makes me an
attractive ~~mark~~ reviewer for editors. Here I was
tsk-tsking the elders of the field on sloppiness, and then running
into them just a few weeks later. Anonymity wasn't enough to protect
me...so I'd use different "voices" in my reports. There was the uptight
grammarian
who never ended a sentence with a proposition, no matter how awkward
things might get. Then there was the folksy neighbor using non-words
such as "ain't" and beginning sentences with "And another thing..."

So for this blog, it's tough. I'd love to tell stories about meeting
famous physicists, or casually bring up some invitation to speak. Or
even just pointing out interesting papers on the arXiv. But this
community is small. I was chatting about someone's research last week
and wanted to make fun of what a certain physics blogger we all know
and love would think of the work. Just an hour later, looking at some of
this guy's previous papers, he's published with that same physicist!

Anywho, I'm a complainer. I go through financial institutions pretty
quickly. I know this. However, I still maintain that, no matter how
trivial they might be, my complaints are still legitimate. So having
gotten nowhere with one such institution, I closed my accounts with them
and subsequently posted to a finance forum, explaining what happened.
I had heard stories of customers doing similarly and actually hearing
back from institutions trying to make things right in fear of such
social-media-complaints.

So what did I get? Tons of pity, sympathy, advice, consolation? Oh no.
There was some biting, albeit funny, jokes speculating what kind of
curmudgeon I was. But mostly it was people lambasting me expecting
good service and for complaining. Indeed, they just assumed
I had yelled at the CSR on the phone despite the fact that I neither
yelled nor mentioned yelling in my post. People were mean and, I was actually
a bit surprised that it had any effect on me. Here I was, anonymously
posting, and people's hurtful comments about an issue that was done
and over with were bothering me. It's hard for me to even extrapolate
what some teenager might go through with non-anonymous trashing in
social media.

So I concluded that people pretty much suck. They litter, they smoke
near entryways, they drive slowly in the passing lane, and they
perpetuate annoyances such as Rush Limbaugh and Nigerian email scams,

Anyway, one of the things I struggle to communicate concerns the drive
in this profession. I'm friends with a wide range of physicists. The
spectrum pretty much spans the range from those content to teach a few
classes and who do no research...to those who have many pots in the fire,
students working on all manner of things, running from collaborative
meeting to another. I say it's a spectrum, but if one actually introduced
a measure on it, I doubt they're many in between the extremes. I
suspect it's a pretty bimodal distribution. Me? I'm special. Neh, rare!

I always maintain a few pots in the fire, but I'm pretty laid back. I
have a competitive drive to compete with peers. But at the same time,
I want to enjoy the trip. And really I'm not sure where the drive
comes from. It's not that I enjoy the competition.

Everyone gather round to read a solipsist's blog!

2011-09-30T13:06:00.000-07:00

Great title: Static Patch Solipsism: Conformal Symmetry of the de Sitter Worldline...but can you use such a great word in the title without also including it in the text?
By now most everyone has heard about the new FTL result of OPERA. It's really such a shame, but it was fun while it lasted. I mean the climate scientists have long since begun to lose their stranglehold on the AGW conspiracy, so it was only a matter of time until the entire edifice of modern physics is torn down. Of course relativity and quantum mechanics was a snow-job to fool the common person! I mean if Joe-schmoe can't understand it, then it must be wrong. And if it's wrong and more than one person says it, then it is, by construction, a conspiracy. It's now only a matter of a few years until this nightmare of "modern science" is completely ripped asunder and we'll entire a utopia ruled by complete gun and religious freedom. That is to say, the freedom to be white, armed Christians (preferably no Catholics) in the unquestioned greatest country on Earth.

...removing tongue from cheek now.

Hello New Students

2011-09-02T14:31:00.000-07:00

This is introductory physics. The goal for this course is three-fold: (i) better understanding of how the universe works at a pretty fundamental level (in other words, this is not biology or chemistry), (ii) better problem solving ability, and (iii) increased quantitative awareness and ability. Students are often intimidated coming into a course such as this. I do not wish to make it hard, but you have to demonstrate some achievement in these three goals.

To give you some sense of how I see the grading in this course a metaphor is in order. Let's say that I'm here to teach you all basketball. You all come in with very different abilities. My tests will have a range of questions...some will be like free throws. An example would be: How much force would one have to exert to accelerate a 2 kg ball at a rate of 3 m/s^2? Some may have no numbers and might be comparable to asking someone to evaluate what kind of defense an opposing team is running. For example, I could ask: What force is responsible for holding a bag of concrete on the back of a flatbed truck as it drives down the highway? More difficult problems might be something like having you carry-out a give-and-go. All of this is definitely teachable, though some will have no problem at all. You all can do this. And, just like in basketball, it will take practice.

Some more involved problems will challenge nearly everyone. They are more akin to looking for you to demonstrate court-awareness and the ability to break-down a defense. You will have to introduce variables not given in the problem, determine a number of equations, and use your math skills to solve them. This can be taught, but is fairly advanced.

In any case, please be aware that you may make a habit of "hiding" in other classes, hoping that the instructor isn't particularly aware of how little one might know. This class doesn't really allow this. I will have a very good idea of both your ability and your understanding, regardless of how little you may participate in class. I want you all to succeed, but you have to do your part. Good luck!

Hurricane Denial

2011-08-26T19:18:00.000-07:00

If you look at the models of the meteorologists for the track of hurricane Irene, one can see a huge amount of uncertainty and a lack of agreement. One can also see that these meteorologists benefit immensely from these dire forecasts...afterall, to whom will local governments turn the next time one of these so-called storms appears on the 'radar' screens? I can believe that the East Coast is going to get some rain and wind, but I bet the Sun will peak and all will be well.

My First Scientific American paper...

2011-08-19T13:00:00.000-07:00

Since it's beyond a paywall, let me just give the essentials:

Title:
Needle in a Haystack: Our improbable Universe

About the author:
A former collegiate athlete, the author has been recognized by the APS for his long record of NSF-funded research. Outside of physics, he enjoys skiing, and the occasional glass of wine. A dutiful and doting father, he is generally as much of a prick in person as you might expect from this obnoxious blurb.

Abstract:
Have you ever eaten at a brand new restaurant, and wondered what its chances of success are? More than a metaphor, I establish a correspondence between such a probability and the measure problem of cosmology. Based on how one rates the restaurant, one can thereby deduce a proper normalization to establish the probabilities that others will similarly patronize the establishment. With this insight, I compute the most likely value of the cosmological constant and remarkably find that it occurs with the standard measurement to within 2.31 significant deviations without resorting to any anthropic principle.

Questions

2011-08-05T10:10:00.000-07:00

If I put lots of mouthwash in my mouth is it better than a little? With lots, perhaps I get more cleaning if the wash gets "used up" at all. However, if I go with a little bit, I can really swish it around well and probably get it where it needs to go.
Pandora is really finding some good music today. It's hindering my ability to work.
I orphan lots of my work. I can't remember how many I truly have abandoned, but right now there are two that I'll talk to people about and they ask when the papers are coming out. But they're just not high priority and I only work on them once a year or so. I have two papers to review, an invited talk to prepare, a review to write, and a regular research paper I'm working on. And then in September I've got two proposals to write. But of course, to all my non-physicists friends, I'm somehow "off from work" during the summer!
Why don't European hotels have alarm clocks (or at least some form of clock) in the rooms? Even the crappiest hotel in the U.S. has a clock.
I get that Europeans tend to think of Americans as dumb, uncultured, spoiled babies, and perhaps some of that is deserved. However, if you're going to group me in particular with them when you make fun of them, I'm going to take some offense. Especially when you hardly know me and I've given no particular reason for the grouping. And whatever criticism Americans deserve, this hardly means that Europeans are particularly well-behaved or cultured. On the whole, they can be as rude and crass. Of course, by necessity they're very likely going to be more aware of the world.

Cosmic Deviants

2011-08-01T09:49:00.000-07:00

Why doesn't the U.S. get the Honda Civic Type R?
Gosh, thanks for the compliment!
This is one way to get physics/physicists into the mainstream media. Speaking of famous atheists, what do atheists, in general, think about the idea of right and wrong? I would think (and actually do) that with no divinity, that right and wrong can have no essential meaning. And so, even the most heinous of activities (say killing for the fun of it) can't be wrong. I imagine this is well established within the entire ethics versus morality difference, but just wanted to make sure. Anyone?

Global warming denial

2011-07-13T13:21:00.000-07:00

The NYT has a good opinion piece expressing an argument I couldn't quite formulate. For me, I suppose, it comes down to the difference in the following two examples:

I believe in ghosts and it's no surprise that scientists can't prove their existence because...
I don't believe in global warming or mankind's contribution thereto because the pro-warming crowd is self-motivated to predict dire things, and I read these retired engineers and meteorologists who have good arguments against aspects of the pro-warming case. And just because there's consensus, the scientific truth of the matter doesn't come down to a vote.

The latter case does not dismiss science, but rather selectively chooses the science they "believe" despite the fact that they have no expertise with which to make such choices.

Electromagnetic wave generation

2011-07-11T14:48:00.000-07:00

I like to think of myself as something of a radical, yet pragmatic, progressive in the U.S. I say 'radical' because I try not to get too hung up on things others might hold dear, and pragmatic because whatever I advocate for has to work. So, for example, I'd be fine with applying the death penalty for a huge variety of crimes, except for the fact that the justice system is just too flawed and unfair. In terms of medical care, in general I wouldn't be too bothered by no universal health care. But if our country is going to allow poor people to use emergency rooms and hence we have to pay ultimately, let's do it in a sane way with preventive care.

And so I really can't understand how so many conservatives expect any sane person of taking them seriously when they go crazy about restrictions on light bulbs. We have so many restrictions in our homes, from our toilets (water conservation) to fire alarms (safety). And jeez, candles are still allowed. Anyone know the efficiency of a candle relative to an incandescent? This seems like a good Fermi-type question and so I'll leave it at that.

Lisa Randall

2011-07-08T17:11:00.000-07:00

Umm, not sure what compels Lisa Randall (of Warped Passages fame) to publicly comment on the musical The Book of Mormon, but she's very much a public figure so why not.

Turning the tables

2011-07-01T09:15:00.000-07:00

Dear Editors,

We unfortunately wish to inform you that your journal has not been accepted for our manuscript. Although your journal is very well-respected (perhaps, because of this reputation), the evaluation of our own anonymous referee indicates serious problems with your publication process. In particular, as is clear from the reports you provided, you received seriously flawed reviews of our manuscript, one indicating total incompetence and the other sheer pomposity. However, our referee also faulted the acceptance process itself. In particular, as editors, one of your roles is to actually edit the paper instead of delegating such work back on the authors. Fine details, picky formatting rules, and simple tweaking should not be passed onto the authors.

We have decided instead to simply note on the arXiv record for our manuscript that, ultimately, it was accepted by your publication. If you would like to appeal this decision, please contact the first author. We hope that perhaps in the future you will consider receiving another of our manuscripts.

Respectfully,
the authors

Judging People

2011-06-24T12:33:00.000-07:00

I like to think I'm not a really judgmental person. Certainly not in terms of one person being "better" than another. If someone lingers just outside the entrance to a building smoking and then tosses the cigarette on the ground, I'll certainly think ill of them, but not in terms that I'm somehow better than they.

In any case, when it comes to physics you must judge, in terms of ability. You need to find out if you might want to work with them, or what particular knowledge/experience you can take advantage of with questions and which questions you might as well not ask.

So when I google people after seeing them at conferences, you can usually find out their pedigree (education, advisors, etc). It's usually better to judge by asking them questions, but sometimes you use shortcuts. So when I find paragraphs written by them online and they're horribly written, that's not a good sign. When I then see that they were English or other liberal art majors at one point and they have grammatical errors, I judge them harshly.

And then there's the issue of what schools they've attended. Despite the fact that I attended a very elite school, I try not to count this much. But if they've attended some non-elite school and follow that up with a non-elite grad school, it's hard not to feel that they've essentially got to prove their worth to you.

Physics in Fiction

2011-06-14T17:20:00.000-07:00

I saw the movie Rabbit Hole recently. Pretty decent and not terribly long. Not a fun movie though. The reason I mention it here is that the idea of parallel universes makes an appearance (as in the universes associated with eternal inflation, not quantum mechanics; or are they the same thing (see Sean's recent discussion]). Anyway, I thought its mention was largely sensible and reflects a bit how physics shapes ones worldview. This contrasts sharply with the physics one often sees as something else...something bad (as in weapons) or geeky (e.g. a Seth Green type role) or hard (e.g. Breakfast Club [one of the best ever]).

Give a man a fish...

2011-06-13T17:13:00.000-07:00

A couple of recent posts, one by Chad and the other by the Female Science Professor, have me thinking about what we owe to our students.

For starters, I share with Chad an unbroken streak of graduations, but with the opposite polarity. That is, I've never attended my school's graduation ceremony. I don't like crowds, and don't relish having to make small-talk with seldom seen colleagues from across the University.

As for the FSP's commitment to students, for some classes I'll make a PDF of slides available, usually just a half-hour before class and I certainly don't print them out for students. In general, I severely limit how much time I spend on classes. With that said, I do feel a commitment to them, but generally prioritize avoiding diminishing returns. Talking with them, helping them understand, all that stuff I do without hesitation (except in rare cases where I can't stand a student). Elaborate preparation I avoid. Some of my best classes arise when I'm least prepared (though I don't think this should be taken as any sort of advice).

Ostensible

2011-06-09T11:46:00.000-07:00

Yesterday, was a slow day. Certain things had kind of wound down, and I wasn't sure what tasks to do. So I took it easy, caught up on reading some arXiv papers that were clogging up the tabs on my browser. I thought about starting up one of my unimportant (to anyone else), side projects, but I knew things would pick back up...I'd have an idea for the project that's finishing, I'd get a couple emails from folks needing help with their aspects, etc. And now I'm busy, or rather I should be busy, but figured I'd get out this post first.

One other thing, if you're interested in good photography of nature, you might checkout these winning photos. In any case though, you presumably have an interest in physics, so you should definitely checkout the picture of the ocean wave at the beach. One sees these...well I'm not sure what one would call them. Perhaps one would call them vortex lines or just vortices. In any case, pretty cool and dramatic.

Research Projects

2011-05-26T18:24:00.000-07:00

Scott wishes he had a list of research projects for when students come to him wanting to do research. It must be that time of year, because I'm meeting with two students next week about summer research projects. I do have a list of projects, but as Scott mentions, some are trivial and some are incredibly difficult. It's hard to come up with a good project, and even when you do, you've got to match a project to a student's skills and inclination. So no real advice for anyone, but maybe someone has advice for me?
