        <description>&lt;p&gt;The site is now using https.  You should see a padlock in your
browser.  If anything seems broken, please &lt;a href=&quot;/blog/about-me/&quot;&gt;let me know&lt;/a&gt;.&lt;/p&gt;

        <title>Site now powered by Jekyll</title>
        <description>&lt;p&gt;I’ve converted this site from Wordpress to
&lt;a href=&quot;https://jekyllrb.com/&quot; title=&quot;Jekyll&quot;&gt;Jekyll&lt;/a&gt;.  This should give it better
stability and performance.&lt;/p&gt;

&lt;p&gt;One significant change is that comments are no longer supported, since
everything is static pages.  So if you want to share feedback or
commentary on this site, you’ll have to find somewhere else on the
Internet (or &lt;a href=&quot;/blog/about-me/&quot;&gt;contact me directly&lt;/a&gt;).
However, this does mean you won’t see spam or other abusive content
here.&lt;/p&gt;

        <title>An intriguing invitation from &lt;i&gt;Advances in Pure Mathematics&lt;/i&gt;</title>
        <description>&lt;p&gt;Now here’s an offer that’s pretty hard to resist.&lt;/p&gt;

&lt;blockquote&gt;
  &lt;p&gt;Invitation to Join Our Editorial Board&lt;/p&gt;

  &lt;p&gt;Advances in Pure Mathematics&lt;/p&gt;

  &lt;p&gt;ISSN Online: 2160-0384&lt;/p&gt;

  &lt;p&gt;Dear Dr. Nathaniel Eldredge,&lt;/p&gt;

  &lt;p&gt;The Advances in Pure Mathematics (APM, ISSN: 2160-0384 ), plans to recruit new members of the Editorial Board to serve an initial one-year term with renewal options. In view of your outstanding contributions in this area,&lt;/p&gt;

  &lt;p&gt;I am pleased to invite you to apply to be a member of the Editor Board. More information about it can be found at the following website: www.scirp.org/journal/apm.&lt;/p&gt;

  &lt;p&gt;Benefits of the position&lt;/p&gt;

  &lt;p&gt;•  Collaborating with an international editorial leadership team&lt;/p&gt;

  &lt;p&gt;•  Mentoring authors from all over the world&lt;/p&gt;

  &lt;p&gt;•  Receiving editorial reviewing resource materials&lt;/p&gt;

  &lt;p&gt;•  Participating in research projects to improve the editorial process&lt;/p&gt;

  &lt;p&gt;•  Acquiring knowledge on the latest innovations in qualitative inquiry&lt;/p&gt;

  &lt;p&gt;•  Gaining a valuable credential for tenure and promotion review&lt;/p&gt;

  &lt;p&gt;Relevant Information&lt;/p&gt;

  &lt;p&gt;Members of the board are expected to recommend papers for publication, help to review submitted manuscripts and provide suggestions to promote the journal. If you are interested or have any person to recommend, please feel
free to send your questions or application (including your research areas of interest and CV) to Editorialmanagement@scirp.org&lt;/p&gt;

  &lt;p&gt;APM Editorial Office&lt;/p&gt;
&lt;/blockquote&gt;

&lt;p&gt;Tempting… very tempting. I’d be in &lt;a href=&quot;https://www.scirp.org/Journal/EditorialBoard.aspx?JournalID=513&quot; title=&quot;APM editorial board&quot; target=&quot;_blank&quot;&gt;distinguished company&lt;/a&gt;, and it would be so rewarding to serve the scientific community as a part of APM’s &lt;a href=&quot;https://thatsmathematics.com/blog/archives/102&quot; title=&quot;Mathgen paper accepted!&quot; target=&quot;_blank&quot;&gt;rigorous peer-review process&lt;/a&gt;…&lt;/p&gt;

        <title>Mathgen book proceeds donated to AMS</title>
        <description>&lt;p&gt;Today I received the first check from &lt;a href=&quot;https://www.lulu.com&quot; title=&quot;Lulu&quot;&gt;Lulu&lt;/a&gt; with the proceeds from the first few months of &lt;a href=&quot;https://thatsmathematics.com/blog/mathgen-books&quot; title=&quot;Mathgen Books&quot;&gt;Mathgen book sales&lt;/a&gt;: US$76.32. I’ve just dispatched a check for the same amount to the &lt;a href=&quot;https://www.ams.org&quot;&gt;American Mathematical Society&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;Thanks to all who bought the books! Not only do you now own a fantastic conversation piece, but you’ve helped support real (non-randomly generated) mathematics research! And for those who haven’t: &lt;a href=&quot;https://thatsmathematics.com/blog/mathgen-books&quot; title=&quot;Mathgen Books&quot;&gt;you still can&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;&lt;strong&gt;Update:&lt;/strong&gt; In the interests of transparency, &lt;a href=&quot;https://thatsmathematics.com/blog/wp-content/uploads/2013/02/ams2.pdf&quot;&gt;here is the receipt (PDF)&lt;/a&gt;.&lt;/p&gt;

        <title>Another Mathgen paper accepted</title>
        <description>&lt;p&gt;&lt;a href=&quot;https://www.mi.uni-koeln.de/~stfriedl/&quot; target=&quot;_blank&quot;&gt;Stefan Friedl&lt;/a&gt; of the University of Cologne writes with the news that he has gotten a &lt;a href=&quot;https://thatsmathematics.com/blog/mathgen&quot; title=&quot;Mathgen&quot;&gt;Mathgen&lt;/a&gt; paper accepted by &lt;em&gt;&lt;a href=&quot;https://mililink.com/journals_desc.php?id=62&quot; title=&quot;JANTA&quot; target=&quot;_blank&quot;&gt;Journal of Algebra and Number Theory Academia&lt;/a&gt;&lt;/em&gt;. (Yes, that’s really the name of the journal; it was nominated for &lt;a href=&quot;https://recursed.blogspot.de/2010/09/new-journal-with-clunky-name.html&quot; target=&quot;_blank&quot;&gt;Clunkiest New Journal Title of 2010&lt;/a&gt;.)&lt;/p&gt;

&lt;p&gt;Friedl’s masterpiece is entitled “On the uniqueness of prime, Jacobi functors”; you can &lt;a href=&quot;https://thatsmathematics.com/blog/wp-content/uploads/2013/01/friedl.pdf&quot; target=&quot;_blank&quot;&gt;read the manuscript (PDF)&lt;/a&gt;. Its abstract:&lt;/p&gt;

&lt;blockquote&gt;
  &lt;p&gt;Let \(\delta^{(\Omega)} \le i\) be arbitrary. Every student is aware that every factor is independent. We show that \(\bar{f}\) is co-trivial and extrinsic. In this context, the results of [32] are highly relevant. On the other hand, in [32], the authors address the reversibility of additive scalars under the additional assumption that there exists a compactly semi-Monge locally symmetric monodromy.&lt;/p&gt;
&lt;/blockquote&gt;

&lt;p&gt;The anonymous referee’s report offers unqualified praise for this magnificent paper:&lt;/p&gt;

&lt;blockquote&gt;
  &lt;p&gt;I have gone through the paper. It is a good paper. In my view the results obtained are original, new and interesting. This paper may trigger further research in the direction of work.&lt;/p&gt;

  &lt;p&gt;Clarity: This paper is well-written and well-presented.&lt;/p&gt;

  &lt;p&gt;Literature: The authors’ references to the literature seem adequate.&lt;/p&gt;

  &lt;p&gt;Interest: Readers of the journal will find this paper interesting.&lt;/p&gt;

  &lt;p&gt;Recommendation: I recommend that this paper be accepted for publication in the Journal for Algebra and Number Theory Academia.&lt;/p&gt;
&lt;/blockquote&gt;

&lt;p&gt;Unlike &lt;a href=&quot;https://thatsmathematics.com/blog/archives/102&quot; title=&quot;Mathgen paper accepted!&quot; target=&quot;_blank&quot;&gt;&lt;em&gt;Advances in Pure Mathematics&lt;/em&gt;&lt;/a&gt;, JANTA is not an open-access journal but is available only by subscription; &lt;a href=&quot;https://mililink.com/onlinepurchase.php&quot; target=&quot;_blank&quot;&gt;current subscription rates&lt;/a&gt; are US$300 per year (6 issues). They do, however, require that the author pay an “article processing charge” of US$20 per page. Friedl also points out that JANTA is &lt;a href=&quot;https://www.zentralblatt-math.org/zmath/en/journals/search/?an=00007229&quot; target=&quot;_blank&quot;&gt;indexed by Zentralblatt&lt;/a&gt;, a well-respected review database.&lt;/p&gt;

&lt;p&gt;Congratulations to Stefan for his successful work!&lt;/p&gt;

        <title>Radio interview about Powerball lottery</title>
        <description>&lt;p&gt;With the current large &lt;a href=&quot;https://powerball.com&quot; title=&quot;Powerball&quot; target=&quot;_blank&quot;&gt;Powerball&lt;/a&gt; lottery jackpot, the media is pretty excited. I got interviewed this morning by Lee Rayburn of &lt;a href=&quot;https://www.whcu870.com&quot; target=&quot;_blank&quot;&gt;WHCU radio&lt;/a&gt; about the lottery, its odds, and so on. You can &lt;a href=&quot;https://www.whcu870.com/topic/play_window.php?audioType=Episode&amp;#038;audioId=6137607&quot; target=&quot;_blank&quot;&gt;listen online&lt;/a&gt; or &lt;a href=&quot;https://www.whcu870.com/episode_download.php?contentType=36&amp;#038;contentId=6137607&quot; target=&quot;_blank&quot;&gt;download as MP3&lt;/a&gt;.&lt;/p&gt;

&lt;p&gt;Note: I just noticed they gave me a promotion; my title at Cornell is “Visting Assistant Professor”, not “Visiting Professor”.&lt;/p&gt;

        <title>Fake airline email FAIL</title>
        <description>&lt;p&gt;I just got an email, nominally from Southwest Airlines, advising me of my upcoming itinerary:&lt;/p&gt;

&lt;div class=&quot;language-plaintext highlighter-rouge&quot;&gt;&lt;div class=&quot;highlight&quot;&gt;&lt;pre class=&quot;highlight&quot;&gt;&lt;code&gt;2012-11-20
Depart SAN LEONARD CITY IL (SLC) at 6:30 PM on Southwest Airlines
Arrive in PHOENIX CA (PHX) at 2:19 PM
&lt;/code&gt;&lt;/pre&gt;&lt;/div&gt;&lt;/div&gt;

&lt;p&gt;So apparently &lt;a href=&quot;https://https://en.wikipedia.org/wiki/Salt_Lake_City_International_Airport&quot; target=&quot;_blank&quot;&gt;SLC&lt;/a&gt; is not Salt Lake City but a nonexistent city in Illinois, Phoenix is in California now, and flying between them takes negative 2 hours and 11 minutes (even after accounting for time zones).&lt;/p&gt;

&lt;p&gt;Yep, seems legit!&lt;/p&gt;
