Debate!

Before I did math, I did debate.
And now I’ve found a way to reconcile the two! Gil Kalai is a great researcher in theoretical computer science who has written several articles that are skeptical of the possibility of quantum computers ever being built. I think his ideas are interesting, but wrong.
So we’ve agreed to debate on the neutral territory of Dick Lipton and Ken Regan’s blog, Godel’s Lost Letter.
The debate begins with Gil laying out his case for skepticism of quantum computing.
In a few days, I’ll post my reply there. Stay tuned…

Why boycott Elsevier?

Everyone has their own reasons for doing this. There is an interesting debate at Gower’s blog, including a response from an Elsevier employee. Some people dislike Elsevier’s high prices, their bundling practices, their fake medical journals, their parent company’s (now-former) involvement in the global arms trade, their lobbying for SOPA/PIPA/RWA, or other aspects of their business practice. Indeed, for those who want to reform Elsevier, this is one limitation of the boycott, in that it doesn’t clearly target a particular practice of the company that we want changed. On the other hand, others think Elsevier isn’t evil, but just has a communications problem.
In this post, I want to defend a more radical position, which is that we should try not to reform Elsevier or other publishers of academic journals, but to eliminate them. Until the debate over SOPA, I thought this position was too extreme. I thought we could tolerate a status quo in which journals are used for credentialing, and although it is a little unjust and absurd, the only real cost is bleeding the library budgets a little bit.
But the status quo isn’t stable. Open access and self-archiving are expanding. Soon, someone will successfully mirror JSTOR. Libraries are increasingly complaining about subscription costs.
In the long run, the future looks more like arxiv.org. Their front page boasts (as of this writing):

Open access to 731,335 e-prints in Physics, Mathematics, Computer Science, Quantitative Biology, Quantitative Finance and Statistics.

Just like the walled gardens of Compuserve and AOL would never grow into the Internet, no commercial publisher will ever be able to match the scope and ease of access of arxiv.org. Nor can they match the price. In 2010, there were about 70,000 new papers added to arxiv.org and there were 30 million articles downloaded, while their annual budget was $420,000. This comes to $6 per article uploaded (or 1.4 cents per download). Publishers talk about how much their business costs and how even “open access” isn’t free, but thanks to arxiv.org, we know how low the costs can go.
By contrast, if you want your article published open access with Springer, it costs $3000. This seems like something we might be able to protest, and convince them to change. We can’t. Elsevier’s outgoing CEO left with a golden parachute worth two million pounds. They’re not going to make that kind of money while running with the efficiency of arxiv.org. So while scientists and the public see the internet as a way of sharing knowledge and driving down costs, publishers like Elsevier see it as a threat. For them, $6/article is a nightmare scenario that has to be stopped.
Some of you might think I’m overreacting. After all, publishers have tolerated self-archiving, citeseer, arxiv.org, etc. so far. This is partly to avoid backlash, and partly because for historical reasons editors of journals like Science and Nature have personally supported the advance of science even over the profits of the companies they work for. But in the long run, we can’t both have everything available for free, and journals continuing to charge extortionate prices. I suspect that a conflict is inevitable, and when it happens, we’ll regret the fact that journals hold all of the copyrights. SOPA was the first sign that publishers are not on the side of advancing knowledge, and if a journal ever goes bankrupt and sells its portfolio of intellectual property, we’ll find out what they’re capable of when they no longer are run by people who place any value on science.
So what can we do about it? A boycott of Elsevier is a good first step. But really we need to change the system so that publishers no longer hold copyright. Their role (and rate of profits) would be like that of the local Kinko’s when they prepare course packs. This would also improve the academic societies, like ACM and APS, by removing the terrible incentive that their publishing gives them to support organizations like the AAP that in turn support SOPA. Instead, they could simply represent communities of scientists, like they were originally designed to do.
I’m not idealistic enough to imagine that arxiv.org is enough. The issue is not so much that it lacks refereeing (which could be remedied easily enough), but that it lacks scarcity. To see what I mean, imagine starting a free online-only virtual journal that simply selects papers from the arxiv. The entire journal archives could be a single html file of less than a megabyte. But without space constraints, it would need to credibly signal that papers accepted into it were high quality. This is nontrivial, and involves convincing authors, readers, referees and hiring committees, all more or less simultaneously. As a community, we need to figure out a way to do this, so that the internet can finally do what it was designed for, and disrupt scientific publishing.
Update: Via John Baez, I came across a proposal for replacing academic journals with overlay boards that seems promising.

The cost of knowledge

Tim Gowers has put up a new pledge website against Elsevier.

For many years, academics have protested against the business practices of Elsevier. If you would like to declare publicly that you will not support any Elsevier journal unless they radically change how they operate, then you can do so by filling in your details in the box below.

Why should we boycott Elsevier? We’ve blogged before about Elsevier and highlighted their support of SOPA. They’ve also supported and lobbied for PIPA and the Research Works Act. As Aram commented on Lance Fortnow’s blog, support for one or more of these is a very direct assertion that you oppose open research and the advancement of knowledge in favor of keeping it behind paywalls and protecting profits. That alone is reason enough, but if you want a few more reasons, go read Tim Gowers’ discussion of their heinous practice of “bundling” a few high-quality journals together with a bunch of low quality journals and forcing libraries to buy the whole package at exorbitant prices.
While you may disagree with choosing such a specific target as Elsevier when many of the problems are endemic to scientific publishing, this is as good a place as any to start, and it can serve as a wake up call to other publishers like Springer that also bundle or to other publishers that supported SOPA et al.
If you are interested in supporting the boycott, then we’ve helpfully compiled a list of every Elsevier journal in computer science, physics and mathematics to help you stick to your pledge. Fortunately in our field there are many strong alternatives, so we don’t have to put our academic careers at risk by publishing in inferior journals while adhering to the boycott.

Unindicted co-conspirators — a way around Nobel's 3-person limit?

This is the time of year the selection process begins for next fall’s Nobel Prizes.  Unlike Literature and Peace, most fields of science have become increasingly collaborative over the last century, often forcing Nobel Committees to unduly truncate the list of recipients or neglect major discoveries involving more than three discoverers, the maximum Nobel’s will allows.  A possible escape from this predicament  would  be to choose three official  laureates randomly from a larger set of names, then publish the entire set, along with the fact that the official winners had been chosen randomly from it.   The money of course would go to the three official winners, but public awareness that they were no more worthy than the others might induce them to share it.  A further refinement would be to use weighted probabilities, allowing credit to be allocated unequally, with a similar incentive for the winners to share money and credit according to the published weights, not the actual results, of the selection process.
If the Nobel Foundation’s lawyers could successfully argue that such randomization was consistent with Nobel’s will, the Prizes would better reflect the collaborative nature of modern science, at the same time lessening unproductive competition among  scientists to make it into the top three.

referee Hall of Fame/Shame

At the Pontiff, we are big fans of Science 2.0 in all its forms. But even within the traditional journal system, there are ways to improve the peer review system. One tragedy of peer review is how little credit the referees get for doing good work, and how there’s nothing to trouble them if they don’t but their own guilty consciences and a bunch of emails from an editor.
One approach I recently came across is from an economics journal. They publish a list of their associate editors, together with average turnaround time for manuscripts.

etc.

This is a nice start, but surely we could do more. When I teach, I get student evaluations. What if the authors of the papers I refereed also gave me 1-5 stars as a reviewer? Before you mention the obvious problem, the way to average the ratings would be by outcome: all the “reject outright” ratings are averaged together, all the “revise and resubmit” ratings are averaged together, etc., before these are all combined into a final score. That way, you couldn’t get high ratings just by always accepting everything.
Clearly this proposal still needs more work. Any ideas?

strike!

In a move that will undoubtedly bring the US Senate to its knees, the Quantum Pontiff is going dark from 8am to 8pm EST on Jan 18 to protest SOPA, PIPA, the Research Works Act and other proposed acts of censorship.
We suggest you use this time to contact your representatives, read a book (or 1201.3387), or go outside.

Correcting Untruths

We here at the Quantum Pontiff value truth in all its forms: theorems, lemmas, statistical inference, and hard experimental data, to name just a few. So I feel compelled to highlight the following.
In his column on the New York Times website, Author S. Brisbane states,

I’m looking for reader input on whether and when New York Times news reporters should challenge “facts” that are asserted by newsmakers they write about.    …
[An] example: on the campaign trail, Mitt Romney often says President Obama has made speeches “apologizing for America,” a phrase to which Paul Krugman objected…
As an Op-Ed columnist, Mr. Krugman clearly has the freedom to call out what he thinks is a lie. My question for readers is: should news reporters do the same?

What are we teaching journalism students that would lead them to ask this question in ernest? After double checking my calendar to make sure it wasn’t April 1st, I continued reading:

If [reporters should call out lies], then perhaps the next time Mr. Romney says the president has a habit of apologizing for his country, the reporter should insert a paragraph saying, more or less:
“The president has never used the word ‘apologize’ in a speech about U.S. policy or history. Any assertion that he has apologized for U.S. actions rests on a misleading interpretation of the president’s words.”

I’m not sure which is worse… that Mr. Brisbane feels he, a professional journalist, needs to ask his readers for their opinion on how to be a journalist, or that he doesn’t know the answer to this question which looks (to any scientist at least) to be completely obvious.
“Everyone is entitled to his own opinion, but not his own facts,” as a fellow once said. If you don’t know the answer to your question, Mr. Brisbane, then you are a stenographer, not a journalist, and you need to ask yourself why you would bother giving column inches in your newspaper to misinformation and distortions without bothering to correct them. Some things are true; you are not “biasing” anything by printing true statements.

Could Elsevier shut down arxiv.org?


They haven’t yet, but they are supporting SOPA, a bill that attempts to roll back Web 2.0 by making it easy to shut down entire sites like wikipedia and craigslist if they contain any user-submitted infringing material. (Here is a hypothetical airline-oriented version of SOPA, with only a little hyperbole about planes in the air.)
I think that appealing to Elsevier’s love of open scientific discourse is misguided. Individual employees there might be civic-minded, but ultimately they have $10 billion worth of reasons not to let the internet drive the costs of scientific publishing down to zero. Fortunately, their business model relies on the help of governments and academics. We can do our part to stop them by not publishing in, or refereeing for, their journals (the link describes other unethical Elsevier practices). Of course, this is easy to say in physics, harder in computer science, and a lot harder in fields like medicine.
There is another concrete way to stand up for open access. The White House Office of Science and Technology Policy has requested comments on the question of public access to federally-funded scientific research. Comments should be from “non-Federal stakeholders, including the public, universities, nonprofit and for-profit publishers, libraries, federally funded and non-federally funded research scientists, and other organizations and institutions with a stake in long-term preservation and access to the results of federally funded research.” That’s us!
But don’t procrastinate. The deadline for comments is January 2.
Here is more information, with instructions on how to comment.
Here is also the official government Request For Information with more details.

More cracks in the theory of relativity?

When the OPERA collaboration announced their result that they had observed neutrinos traveling faster than the speed of light, it rocked the entire physics community. However, despite the high statistical certainty of the claim, any sober physicist knew that the possibility of systematic errors means that we must patiently wait for additional independent experiments. Einstein’s theory hasn’t been overthrown yet!

Or has it?

Enter the good folks at Conservapedia, a “conservative, family-friendly Wiki encyclopedia.” They have helpfully compiled a list of 39 counterexamples to relativity, and noted that “any one of them shows that the theory of relativity is incorrect.” In fact, relativity “is heavily promoted by liberals who like its encouragement of relativism and its tendency to mislead people in how they view the world.” That is already damning evidence, but you really must look at the list.

A few of them actually have some partial grounding in reality. For example,

6. Spiral galaxies confound relativity, and unseen “dark matter” has been invented to try to retrofit observations to the theory.

Most of them, however, are either factually challenged or irrelevant:

14. The action-at-a-distance by Jesus, described in John 4:46-54, Matthew 15:28, and Matthew 27:51.

18. The inability of the theory of relativity to lead to other insights, contrary to every extant verified theory of physics.

Why are these scientists at OPERA wasting tax payer’s money on their silly experiments when they can just check this list? And to Bill O’Reilly and Rush Limbaugh: please post your predictions for the LHC to the arXiv soon, before all the data gets analyzed.

Update from Aram: Ironically, conservativepedians don’t like Einstein’s relativity because of its occasional use as a rhetorical flourish in support of cultural relativism. (I agree that using it in this manner constitutes bad writing, and a terribly mixed metaphor.) But by denouncing relativity as a liberal conspiracy along with evolution and global warming, they’ve demonstrated their own form of intellectual relativism: the idea that there is no objective truth, but that we are all entitled to believe whatever facts about the world we prefer. At the risk of improving the credibility of Conservapedia, I made this point on their talk page. Let’s see how long it lasts.

Now that's what I call self correcting

credit: University of Illinois

Apparently this is the year for breakthroughs in self-correcting computer hardware. After hearing about Jeongwan Haah’s new self-correcting topological quantum memory at QIP, I just learned, via BBC news, about a new type of (classical) self correcting circuit: one which heals itself when one of the wires cracks! The full paper can be found here, and it is mostly quite readable. The basic idea is to start with a standard classical wire made of (for example) gold. The researchers sprinkled the wire with tiny capsules filled with a metal alloy (Ga-In) which is liquid at room temperature and has high conductivity. Then they bent the circuit board until it cracked, breaking the wire, and hence the circuit. Within milliseconds, the capsules also broke, the cracks filled with the liquid metal, and conductivity was restored. Self correcting, indeed!
One thing I didn’t understand is how the liquid metal stays in the cracks. I guess that at the scale they are working at, the surface tension alone is sufficient to keep the liquid metal in place?
