Is the Los Angeles Times Simply Publishing Press Releases for Companies Like Barnes & Noble?

The Los Angeles Times published an online article entitled “Barnes & Noble says e-books outsell physical books online.” While I understand that this is a quiet holiday week, the Times should be doing better work than simply republishing press releases from corporations trying to garner post-holiday sales.  Some of the thoughts they might have included:

“Customers bought or downloaded 1 million e-books on Christmas day alone”?

There is certainly no debating the continuous growth of the electronic book industry; even has said they’re selling more electronic books than physical books. The key word in the quoted sentence above is “or”. I seriously doubt a significant portion of the 1 million e-books were actually purchased on Christmas day. The real investigative journalism here would have discovered the percentage of free (primarily public domain) e-books that were downloaded versus those that were purchased.

Given that analysts estimate 2 million Nooks have sold (the majority within the last six months and likely the preponderance of them since Thanksgiving) this means that half of all Nook users downloaded at least one book on Christmas day. Perhaps this isn’t surprising for those who would have received a Nook as a holiday present and may have downloaded one or more e-books to test out its functionality. The real question will remain, how many of these 2 million users will actually be purchasing books in e-book format 6 months from now?

I’d also be curious to know if the analyst estimate is 2 million units sold to consumers or 2 million shipped to retail? I would bet that it is units shipped and not sold.

I hope the Times will be doing something besides transcription (or worse: cut and paste) after the holidays.



The Decline Effect and the Scientific Method | The New Yorker

The Truth Wears Off: Is there something wrong with the scientific method? by Jonah Lehrer(The New Yorker)

Jonah Lehrer’s New Yorker article “The Truth Wears Off: Is there something wrong with the scientific method?” is an interesting must-read article. In it he discusses the “Decline Effect” and outlier statistical effects within scientific research.

Among other interesting observations in it, he calls attention to the fact that, “according to the journal Nature, a third of all studies never even get cited, let alone repeated.”

For scholars of Fisher, Popper, and Kuhn, some of this discussion won’t be quite so novel, but for anyone designing scientific experiments, the effects discussed here are certainly worthy of notice and further study and scrutiny.

New Measures of Scholarly Impact | Inside Higher Ed

New Measures of Scholarly Impact(
Data analytics are changing the ways to judge the influence of papers and journals.

This article from earlier in the month has some potentially profound affects on the research and scientific communities. Some of the work and research being done here will also have significant affect on social media communities in the future as well.

The base question is are citations the best indicator of impact, or are there other better emerging methods of indicating the impact of scholarly work?

Poor State of Automated Machine-Based Language Translation

You know that automated machine language translation is not in good shape when the editor-in-chief of the IEEE’s Signal Processing Magazine says:

As an anecdote, during the early stage in creating the Chinese translation of the [Signal Processing] magazine, we experimented with automated machine translation first, only to quickly switch to professional human translation.  This makes us appreciate why “universal translation” is the “needs and wants” of the future rather than of the present; see [3] for a long list of of future needs and wants to be enabled by signal processing technology.

Improved Reading and Workflows with Instapaper and Tab Candy aka Panorama for Firefox

Over the summer, Ars Technica and others reported about the new feature Tab Candy being built into Firefox by Aza Raskin.  Essentially it’s a better graphical way of keeping “tabs” on the hundreds of tabs some of us like to keep open for our daily workflows.  One can now group series of related tabs together and view them separately from other groupings.  Many of us loved the feature in the early Minefield build of Firefox, but the recent release of Firefox 4.0 beta 7 includes the nearly finished and stable version of Tab Candy, which has been renamed Panorama, and it is great.

Though Panorama is a brilliant, one of the functionalities it doesn’t have and which is mentioned in the Ars Technica article, is that of “reading later.” I find, as do many, that the majority of the tabs I keep open during the day are for things I have the best intentions of reading later.  Sadly, often days go by and many of these tabs remain open and unread because I simply don’t have time during the work day and don’t come back later in my free time to give them the attention they deserve.  (It also coincidentally has the side effect of soaking up additional memory, a symptom which can be remedied with this helpful tip from Lifehacker.)

I’ve now got the answer for these unread stories in neglected tabs:  Instapaper, the brainchild of former Tumblr exec Marco Arment, is similar to many extant bookmarking tools, but with increased functionality that makes it infinitely easier to come back and actually read those stories.  Typically I use the Instapaper bookmarklet tool on a webpage with a story I want to come back to later, and it bookmarks the story for me and is configurable to allow closing that tab once done.

The unique portion of the tool is that Instapaper provides multiple ways of pulling out the bookmarked content for easy reading later.  For those who are RSS fans, you can subscribe to your bookmarked stream with tools like Google Reader.  But even better, the site allows one to easily download .mobi or .epub bundled files of the stories that can be put onto your e-reader of choice.  (I personally email copies to my Kindle 3 (affiliate link.)) Once this is done, I can simply and easily read all those stories I never got around to, reading them like a daily personal newspaper at my convenience – something I’m much more prone to do given my addiction to my Kindle, which provides a so-called “sit back experience.”

As if all this isn’t good enough, Instapaper allows you to create differentiable folders (along with separate requisite RSS feeds and bookmarklet tools) so that you can easily separate your newspaper articles from your tech articles, or even your communication theory research papers from your genetics scientific articles.  This can allow you to take your daily twitter feed article links and turn them into a personalized newspaper for easy reading on your choice of e-book reader.  With the upcoming pending Christmas of the e-reader and tablets, this is as close to perfect timing for the killer app as a developer could hope.

The e-book reader combined with Instapaper is easily the best invention since Gutenberg’s original press.

(N.B.: One could bookmark every interesting article in the daily New York Times and read them in e-book format this way, but I would recommend using an application like Calibre for reducing the time required for doing this instead. Instapaper is best used as a custom newspaper creator.)

Paul Halmos on Prerequisites

Definitely the quote of the day:

Paul Halmos (1916 – 2006, Hungarian-born American mathematician
in Measure Theory (1950)


This is essentially the mathematician’s equivalent of the adage “Fake it ’til you make it.”

Riemann’s On the Hypotheses Which Lie at the Foundations of Geometry

One must be truly enamored of the internet that it allows one to find and read a copy of Bernhard Riemann’s doctoral thesis Habilitation Lecture (in English translation) at the University of Göttingen from 1854!

His brief paper has created a tsunami of mathematical work and research in the ensuing 156 years. It has ultimately become one of the seminal works in the development of the algebra and calculus of n-dimensional manifolds.

Brief Thoughts on the Google/Verizon Compromise and Net Neutrality in the Mobile Space

This last week there’s been a lot of interesting discussion about net neutrality as it relates particularly to the mobile space.  Though there has been some generally good discussion and interesting debate on the topic, I’ve found the best spirited discussion to be that held by Leo Laporte, Gina Trapani, Jeff Jarvis, and guest Stacey Higginbotham on this week’s episode of This Week in Google.

What I’ve found most interesting in many of these debates, including this one, is that though there is occasional discussion of building out additional infrastructure to provide additional capacity, there is generally never discussion of utilizing information theory to improve bandwidth either mathematically or from an engineering perspective.  Claude Shannon is rolling in his grave.

Apparently, despite last year’s great “digital switch” in television frequencies from analog to provide additional television capacity and the subsequent auction of the 700MHz spectrum, everyone forgets that engineering additional capacity is often cheaper and easier than just physically building more.  Shannon’s original limit is far from a reality, so we know there’s much room for improvement here, particularly because most of the improvement on reaching his limit in the past two decades has come about particularly because of the research in and growth of the mobile communications industry.

Perhaps our leaders could borrow a page from JFK in launching the space race in the 60’s, but instead of focusing on space, they might look at science and mathematics in making our communications infrastructure more robust and guaranteeing free and open internet access to all Americans?

Global classical solutions of the Boltzmann equation with long-range interactions

Global classical solutions of the Boltzmann equation with long-range interactions(

Finally, after 140 years, Robert Strain and Philip Gressman at the University of Pennsylvania have found a mathematical proof of Boltzmann’s equation, which predicts the motion of gas molecules.


This is a brief announcement of our recent proof of global existence and rapid decay to equilibrium of classical solutions to the Boltzmann equation without any angular cutoff, that is, for long-range interactions. We consider perturbations of the Maxwellian equilibrium states and include the physical cross-sections arising from an inverse-power intermolecular potential r-(p-1) with p > 2, and more generally. We present here a mathematical framework for unique global in time solutions for all of these potentials. We consider it remarkable that this equation, derived by Boltzmann (1) in 1872 and Maxwell (2) in 1867, grants a basic example where a range of geometric fractional derivatives occur in a physical model of the natural world. Our methods provide a new understanding of the effects due to grazing collisions.


Terence Tao Teaching Real Analysis at UCLA this Fall

Holy cow! I discovered on Friday that Terence Tao, a Fields Medal winner, will be teaching a graduate level Real Analysis class this fall at UCLA.


Surprisingly, to me, it ony has 4 students currently enrolled!! Having won a Fields Medal in August 2006, this is a true shock, for who wouldn’t want to learn analysis from such a distinguished professor? Are there so few graduate students at UCLA who need a course in advanced analysis? I would imagine that there would be graduate students in engineering and even physics who might take such a course, but perhaps I’m wrong?

Most of his ratings on RateMyProfessors are actually fairly glowing; the one generally negative review was given for a topology class and generally seems to be an outlier.

On his own website in a section about the class and related announcements we seem to find the answer to the mystery about enrollment.  There he says:

 I intend this to be a serious course, focused on teaching the material in the course description.  As such, students who are taking or auditing the course out of idle curiosity or mathematical “sightseeing”, rather than to learn the basics of measure theory and integration theory, may be disappointed.  I would therefore prefer that frivolous enrollments in the class be kept to a minimum.

This is generally sound advice, but would even the most serious mathematical tourists really bother to make an attempt at such an advanced course? Why bother if you’re not going to do the work?!

Fans of the Mathematical Genealogy Project will be interested to notice that Dr. Tao is requiring his Ph.D. advisor’s text Real Analysis: Measure Theory, Integration, and Hilbert Spaces. He’s also recommending Folland‘s often used text as well, though if he really wanted to scare off the lookie-loos he could just say he’ll be using Rudin‘s text.
