Strange happenings at arXiv.org

Update: All seems to be well at the arXiv site now. Still no word about what happened.

This morning I read a tweet from Daniel Lemire saying that some papers have gone missing from arXiv.org, the primary repository for preprints in physics and some areas of mathematics and computer science. I checked and it seemed that a lot of more recent papers were missing in several searches that I tried.

Just now, I heard from Martin Roetteler that arXiv.org is redirecting to a random mirror site, e.g. the Australian, Brazilian or Chinese mirror. At the time of writing, at least the mirror sites seem to be working correctly.

Speculation is that perhaps the arXiv has been hacked, but at the very least least they are having some pretty major problems with the main servers at Cornell. It comes as a big shock because the arXiv has always been one of the most stable sites that I use regularly and the physics community depends on it. I can’t remember anything like this having happened before.

At the time of writing there is no official comment from the arXiv.

Debunking the Quantum Mystics

Update: Stenger’s book has been reviewed by Steve Esser.

I interrupt the current hiatus of this blog for news of what I think is an important new quantum foundational book.

One of the ways that I follow the latest hot topics in Quantum Schmantum is via a carefully crafted Google Alerts feed, which is quite good at throwing up articles that are getting attention in the mainstream science press. It does need to be carefully crafted though, because a basic search on the word “quantum” is dominated by a James Bond movie, a video game, a 1990′s television series and, worst of all, a whole lot of quantum mystical mumbo jumbo influenced by things like What the Bleep Do We Know, The Secret, Deepak Chopra, etc. Unfortunately, this sort of stuff seems to be more popular than ever and is even getting celebrity endorsment from the likes of Carmen Elektra

.

Unfortunately, however carefully crafted your search is, quite a lot of quantum nonsense will always make it through, so I usually just ignore links with suspect titles. Recently though, the feed has been turning up a lot of links with titles like “Quantum Physics and God”, so much so that I was eventually tempted to click through to see what all the fuss was about. It turns out that these articles were all referring to a new book Quantum Gods: Creation, Chaos, and the Search for Cosmic Consciousness by Victor Stenger who is perhaps best known for his nu athieism book God: The Failed Hypothesis. How Science Shows That God Does Not Exist. Amongst other things, the new book is aimed at debunking the claims of the quantum mystics.

For a long time, I have thought that a book that clearly sets out the case against the quantum mystics is a good idea. I don’t imagine that many people who actually believe in this stuff will read the book, although some may get drawn in by the fact that the title does not suggest that the ideas are going to be debunked. More importantly, however, this is ammunition for scientifically literate people, who may not be well versed in quantum theory, to use when they come up against quantum nonsense.

I have not read the book yet, and I am unlikely to do so in the near future due to my current illness. I would like to add it to my carefully curated Amazon Store of books about quantum theory, but I have a policy of not including any books that I haven’t read, since there are a lot of bad expositions of quantum theory in the popular literature. My main concern is whether Stenger manages to clearly separate the argument against quantum mysticism from his more general concerns about whether or not science is compatible with new age mystical beliefs. In my view, it is one thing to hold a set of new age mumbo jumbo beliefs and quite another thing to believe they are supported by quantum theory. The latter is clearly false, independently of the general debate about new age ideas. For one thing, a large part of the message of things like The Secret and What The Bleep… seems to be that you can make good things happen by the power of positive thinking. I can certainly imagine that this is true to an extent in the realm of human affairs, but that is a matter of psychology and sociology rather than quantum physics. I am encouraged by the fact that Stenger is also the author of a 1997 article from the Skeptical Inquirer, which was my previous go to link for people in need of some quantum debunking. Since I think this is likely to be an important book, I may decide to relax my policy and add the book anyway, provided enough of my trusted colleagues and commenters tell me that the book is accurate. So go out and read!

I’ll leave you with a confrontation between Richard Dawkins and Deepak Chopra, which I couldn’t resist adding to this post.

The three scientific we’s

I am a grammatical pedant. Therefore, for the record, here is the definitive style guide to using “we” in your scientific writing.

There are three different common uses of “we”. Only one of them is evil. Writers on this subject do not usually distinguish them properly, so the discussion often gets horribly confused. I don’t know the correct grammatical terminology (I’m not that much of a pedant), so I’ll just make up my own.

  • “We” used correctly as a pronoun: If there is more than one author on the paper and you are describing something that you actually did as a group, then this is an unambiguously correct usage of “we”.
    Examples:

    “We placed the beaker on the tripod and turned on the bunsen burner.”

    “We ran a numerical optimization algorithm to generate the data in fig. 1.”

    I don’t think there is any problem with this usage of we. If you want to eliminate it then you have to write in the past passive tense, e.g. “The beaker was placed on the bunsen burner and the tripod was turned on.” This might be what you were told to do in high school, but it just makes the text sound cumbersome and boring. Modern style guides do not recommend this any more. The era of past passive tyranny is long gone and I say good riddance!

  • The Royal “we”: There is only one author of the paper and you are describing something that you actually did. The examples are exactly the same as in the previous case.

    I’m not a big fan of this sort of “we”, as it makes you sound like Queen Victoria. Personally, I make a point to use “I” in this context. It sounds funny to me, but a lot of people do it and it is not a very big deal.

  • “We” as in “you and I, dear reader”:
    Examples:

    “In section 20, we show that quantum theory is even weirder than we thought before”

    “Substituting eq. (5) into eq. (4), we see that Newton’s second law is obtained.”

    “If we plot luminosity against distance from the Earth, we obtain fig. 3.”

    This is the evil “we” and should be eliminated at all costs. Eliminating them does not make your writing sound more passive. In fact, the opposite is true because it usually forces you to bring the object to the beginning of the sentence. Most people, including myself, use a lot of “dearest reader we’s” when writing a first draft. OK, maybe it’s not a big crime to let one slip occasionally, but in general I think it is a sign of lazy writing. You will find your sentences shorter, punchier and more direct if you eliminate them completely. In case you don’t believe me yet, here are the de-”we”d examples:

    “Section 20 shows that quantum theory is even weirder than previously thought.”

    “Newton’s second law is obtained from substituting eq. (5) into eq. (4).”

    “Fig. 3 shows a plot of luminosity against distance from the Earth.”

You may be thinking that this post is rather aggressive. If so, I apologize. My Ph.D. thesis advisor made me remove every single “we” from every paper I wrote with him, so I still have some scars from that process.

WARNING: Do not write a comment unless you have understood the distinction between the three uses of “we” described above.

Apologies

The website has not been updated for a long time due to recent illness.  There are two new preprints (see below) and the publications section has been updated.

Get Paid to do Foundations III

‘Tis the season to get employed as a foundations researcher.  Perimeter Institute is currently advertising vacancies for Junior Faculty positions in Quantum Foundations.  See here for more details.  Deadline for applications is Jan 15th.

Get paid to do Foundations II

It seems that this blog is becoming the official website for Quantum Foundations job announcements.  Sadly, in the current climate this still means that I don’t have to bug you with job adverts too often.  In any case, there are two postdocs available via the PIAF (Perimeter Institute — Australia Foundations) partnership, which look like a pretty sweet deal for any finishing postdocs/grad students in Foundations.  They involve spending 9 months of the year in Sydney and 3 months here in Waterloo.  Theoretically, this means that you could completely avoid experiencing winter for the three years of the postdoc.  The job ad is posted here and the deadline is 7th December 2007.

Response from Chicago

The first response to my enquiry from the post on Traditional vs. Online Publishing comes from Jennifer Howard who is an Associate Editor for Physical Sciences at Chicago University press. The response comes in two parts, the first addressing the general issue of whether it is better to publish traditionally or online and the second addressing the specific questions that I asked. Here’s a quote from the first part:

The University of Chicago Press is a non-profit publisher, although we are one of the largest university publishers today . Our primary mission (carefully monitored by the University of which we are a part) is to help disseminate scholarly information. If a given work is already successfully distributed on the internet, my feeling is that a printed book is often not needed. For the prospective author considering whether to post or publish, however, there are a few issues to take into account:

1.) A print book is often better than an online publication when it’s longer than 100 pages. Most people don’t want to read an entire book online, though shorter snippets are usually fine. Most of our external reviewers, for example, decline the opportunity to read the electronic version of a manuscript, asking instead for a hard copy.

2.) A book, published by a university press, has a reputation and vetting process behind it. External experts from the author’s own field review and recommend improvements to the text prepublication. There are also copyeditors correcting typos and checking references. You know something about the quality of what you read or assign in class.

3.) As you mention on your blog, a book has the publisher’s advertising and marketing support behind it.

4.) For more established scientists, a book can be a capstone on a prestigious career. [I confess, I do not usually encourage younger scientists to write books--their case for tenure could be harmed if they are writing books rather than publishing original research articles. If a younger scientist has already written the bulk of the manuscript or feels strongly about publishing a book, however, I will consider it with the same care I would give to a more senior author.]

5.) A book also has a publisher working to secure its translation into other languages, something that is rare for online publications unless you have enterprising volunteers.

6.) A book has permanence–you can always access it, it’s not going to be taken offline or moved when the author goes to another university, gets bored with hosting a website, etc… Books are registered with the Library of Congress, for example, and can sit on the shelf until they are needed.

These are some good points about the benefits of traditional publishing, many of which I missed in my original post. There are a few things I disagree on though:

  • Firstly, if an online manuscript is popular and successful then I think that is exactly when it might be a good idea to publish it as a book, rather than just having the electronic version. Even if they have access to something online, people still want hard copies, and I think the interest generated by the electronic version would actually increase the sales of the book, particularly if the price is not set too high.
  • I’m not sure about the comment about young scientists writing books in point 4. I guess it is good advice in most of Physics, particularly in fast-moving, popular areas of research in which people are primarily judged by publications and citations. However, in less mainstream areas, such as the foundations of physics, having a longer-form to set out your ideas coherently can be a big advantage. Also, what about fields in which it is common practice to publish your Ph.D. thesis as a monograph? The point is just that the validity of this advice is heavily subject-dependent.
  • Point 6 is quite relevant at the moment, but I think it will disappear in the long term. Part of the reason for asking about repositories like arXiv, Connexions and Open Courseware is just that they are supposed to be more permanent than the author’s own website. Eventually, I imagine they will be integrated into the doi system, and that the Library of Congress might want to include them in its catalogues. I agree that the current systems for collating and cataloguing online academic texts are rather haphazard, so this might be a reason to go the traditional route for now.

For the second part of the response, I’ll respond to the responses in a bit more detail:

As some of your commentators suggested would be the case, I cannot claim any of the below responses to be Press policy. Hopefully, they give you a sense of my practices as an editor.

Yes, I would consider a manuscript that has been previously posted on the internet. This isn’t all that unusual and can provide an author with useful feedback.

I do not receive a lot of requests from authors to leave manuscripts online–most are glad to encourage readers to turn to the printed book, given the work they have put into writing the project. There are cases in which our authors have maintained online manuscripts, however, even after publication of their book. If you look at our list prices for these books, you will see why a lot of people are happy to buy them outright.

Well, the fact that leaving something online is an option with Chicago is definitely a plus point. Personally, I think we’ll see an increasing number of authors wanting to do this as a more internet-savvy generation begins to write books. Attitudes to Intellectual Property are changing, so I think academic authors will eventually become less concerned about whether or not people buy the hard copy book.

On posting with other sites. At this point, I haven’t considered this–noone has asked me for the opportunity. To be honest, we would probably have to evaluate it on a case-by-case basis in conversation with the author.

ArXiv.org– I believe a few of our authors probably post early drafts on ArXiv.org for feedback. Most ArXiv readers, however, are more interested in early news of new research. Because books are more often summations of existing literature–for the reference of researchers or for students in courses, I think these drafts are less often consulted at ArXiv. Some of your readers may have additional insight on this.

I know of at least one case of a book on arXiv, which I have mentioned previously on this blog. That’s the recent translation of the 1927 Solvay proceedings by Bacciagaluppi and Valentini (not exactly early news of new research!). Personally, I found the arXiv version enormously helpful.

I don’t think the question of what most arXiv readers currently use it for is particularly relevant. The arXiv can cater to niche audiences as well as mainstream ones. It is pretty flexible, so they could introduce new categories for books if there is the demand. Part of the reason for posting something there would be to have more permanence than you would get on your own website.

On licensing and rights. The licenses you list below can be good, usually if the author does not intend to publish with a publisher. The author at least establishes her or his ownership of the material, though with the internet, any right restrictions that exist in the contract are, in reality, somewhat illusory. Anyone across the world can pick up the material from the web, and it becomes quite difficult to track someone who is using the material in a way that is restricted, moreso to prosecute illegal use.

Agreed. I’m actually imagining that most authors using these licenses would not want many restrictions on how the material is used, particularly with regard to making copies and using the material in lectures. I still think you should ALWAYS explicitly license an electronic book in some way, because it makes it clear to the reader what the allowed usage is and avoids legal ambiguities. I imagine that the license would only be enforced in cases of extreme violation, e.g. if someone is exploiting the work for commercial gain without permission.

Any publisher will need the exclusive right to publish the print book. If one of the licenses below prevented that, we could be in a situation where a fly-by-night operation without a vetting process could publish a version of the book that looks like ours and takes advantage of our reputation and promotion efforts. This, without securing expert review and subsequent revisions or doing the kind of careful copyediting that transforms a manuscript into a published book. This would be harmful to a publisher’s good reputation and ultimately to our books and authors. I would not decline a book because it was licensed under one of these licenses, but we would have to find a way for the Press to be the sole publisher of the material.

This is more or less the answer I expected and is fair enough in the current IP climate. However, some of the licenses I mentioned would definitely be ruled out by this, e.g. I don’t believe the GNU license has provision to distinguish a published version from an electronic version. Probably, one of the Creative Commons licenses allows for this, but I’d have to look into the details to determine which one.
