David had a side interest in physics and was a frequent e-mail correspondent.  From what I recall I first heard from him in 2004 soon after the blog started, with my first reaction when I saw the subject and From line that of wondering why David Gross wanted to discuss that particular article about physics with me.\n<p>Over the years he often sent me links to things I hadn&#8217;t heard about, with always sensible comments about them and other topics.  I had the pleasure of meeting him a couple years ago, when he came to Columbia to drop off his son, who is now a student here.  My condolences to his family and friends.<\/li>\n<li>The AMS has a wonderful relatively new repository of mostly expository documents called <a href=\"https:\/\/www.ams.org\/open-math-notes\">Open Math Notes<\/a>. The quality of these seems to uniformly be high, and this is a great new service to the community. I hope it will grow and thrive with more contributions.<\/li>\n<li>Peter Scholze has now finished his series of talks at the IHES about his ongoing work on local Langlands, the talks are available <a href=\"https:\/\/www.youtube.com\/playlist?list=PLx5f8IelFRgEBJSiTdHD7-WNmPfw9fL89\">here<\/a>.<\/li>\n<li>Jean-Francois Dars and Ann Papillault have a web-site called <a href=\"http:\/\/llx.fr\/site\/histoires-courtes\/\">Histoire Courtes<\/a>, with short pieces in French, many of which are about <a href=\"http:\/\/llx.fr\/site\/tag\/mathematiques\/\">math<\/a> and <a href=\"http:\/\/llx.fr\/site\/tag\/physique\/\">physics<\/a> research.<\/li>\n<li>The LHC is starting to come to life again after a long technical stop.  Machine checkout next week, <a href=\"https:\/\/docs.google.com\/spreadsheets\/d\/1F1fpmpyg2m6bD6G4L7fRmTXJPOheVIR_1GwwQMhpzgQ\/\">recommissioning with beam during May<\/a>, physics starts again in June.<\/li>\n<li>There&#8217;s a new book out with string theory predictions from Gordon Kane, called <a href=\"http:\/\/iopscience.iop.org\/book\/978-1-6817-4489-6\">String Theory and the Real World<\/a>.  Kane has been writing popular pieces about string theory predictions for at least 20 years, with a 1997 piece in Physics Today telling us that string theory was &#8220;supertestable&#8221;, with a gluino at 200-300 GeV.  Over the years, his gluino mass predictions have moved up many times, as the older predictions get falsified.  I don&#8217;t have a copy of the new book, but at <a href=\"https:\/\/books.google.com\/books?id=PJCNDgAAQBAJ\">Google Books<\/a> you can read some of it. From the pages available there I see that<br \/>\n<blockquote><p>the compactified M-theory example we will examine below predicts that gluinos will have masses of about 1.5 TeV&#8230;<br \/>\nThe bottom line is that with about 40 inverse fb of data the limits on gluinos are just at the lower range of expected masses at the end of 2016.<\/p><\/blockquote>\n<p>Right around the time the book was published, results released at Moriond (see <a href=\"http:\/\/www.math.columbia.edu\/~woit\/wordpress\/?p=9187\">here<\/a>) claimed exclusion of gluinos up to about 2 TeV.  Assumptions may be somewhat different than Kane&#8217;s, but I suspect his 1.5 TeV gluino is now excluded.<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>A few quick items: I was very sorry to hear recently of the death of David Goss (obituary here), a mathematician specialist in function fields who was at Ohio State.
