http://www.metafilter.com/157877/Hilary%2DPutnam%2D1926%2D2016
<a href="https://en.wikipedia.org/wiki/Hilary_Putnam">Hilary Putnam</a>, one of the most important analytic philosophers of the last hundred years, <a href="http://www.legacy.com/obituaries/bostonglobe/obituary.aspx?page=lifestory&pid=178040325">died today</a> from mesothelioma. Putnam made numerous significant contributions to philosophy, including contributions to <a href="http://ieas.unideb.hu/admin/file_2908.pdf">epistemology (pdf)</a>, <a href="http://baa.univpgri-palembang.ac.id/perpus-fkip/Perpustakaan/Perpus%20Cero/Filsafat/Filsafat%20Modern/Materialisme%20Modern.pdf#page=245">metaphysics (pdf)</a>, <a href="http://www.princeton.edu/~hhalvors/teaching/phi520_f2012/putnam1980.pdf">logic (pdf)</a>, <a href="http://www.sciencedirect.com/science/article/pii/0315086075901160">philosophy of mathematics (pdf)</a>, <a href="http://www.ninagierasimczuk.com/flt2013/wp-content/uploads/2013/01/Putnam_1965.pdf">philosophy of computation (pdf)</a>, <a href="https://mechanism.ucsd.edu/~bill/teaching/philsci/openheim.putnam.unity.pdf">philosophy of science (pdf)</a>, <a href="http://www.coli.uni-saarland.de/courses/lexsem09/material/u_boltz.pdf">philosophy of language (pdf)</a>, <a href="http://thatmarcusfamily.org/philosophy/Course_Websites/Math_S08/Readings/Putnam_MWF.pdf">philosophy of mathematics again (pdf)</a>, and <a href="http://www.phil.uu.nl/~joel/3027/3027PutnamPsychPredicates.pdf">philosophy of mind (pdf)</a>. (These are really only a small sampling of his contributions: ones that happen to be available online and that I could easily track down. They are mainly included here to indicate the breadth and scope of Putnam's philosophical work, while linking to his papers themselves, as opposed to second-hand reports.)
And here are some videos that show him in action or at least have recordings of his voice:

<a href="https://groups.google.com/forum/#!topic/rec.puzzles/suf8KVdN7nY">The Sleeping Beauty Problem</a> is a problem in probability (rumored to have originated at MIT) that appears trivially simple, yet has inspired some rather sophisticated arguments. <em>We plan to put Beauty to sleep by chemical means, and then we'll flip a
(fair) coin. If the coin lands Heads, we will awaken Beauty on Monday
afternoon and interview her. If it lands Tails, we will awaken her Monday
afternoon, interview her, put her back to sleep, and then awaken her again
on Tuesday afternoon and interview her again.
The (each?) interview is to consist of the one question: what is your
credence now for the proposition that our coin landed Heads?
When awakened (and during the interview) Beauty will not be able to tell
which day it is, nor will she remember whether she has been awakened
before.
She knows the above details of our experiment.
What credence should she state in answer to our question?

(The other three mathematicians who say they have corroborated it have also spent considerable time working alongside Mochizuki in Japan.) The overarching theme of inter-universal geometry, as Fesenko describes it, is that one must look at whole numbers in a different light — leaving addition aside and seeing the multiplication structure as something malleable and deformable. Standard multiplication would then be just one particular case of a family of structures, just as a circle is a special case of an ellipse."

<a href="http://blog.pshares.org/index.php/round-down-the-role-of-writers-in-a-stem-obsessed-society/">The Role of Writers in a STEM Obsessed Society</a> <blockquote>"As writers, it's easy to think of how we matter to literature classrooms, but what the appointment of writers-in-residence in hospitals, history classrooms, foreign language learning spaces, and cooking schools reminds us is that we are relevant wherever there is humanity—which is to say, wherever humans are with their stories. Writing is healing. Writing is art. Writing is learning. As such, writing across the disciplines matters. Many models of artist residencies depend upon the retreat model, wherein the artist sequesters herself away with a small community of other artists. While these models have value, especially when considering how solitude relates to the creative process, it's heartening to me to see more models catch on that value the place of the writer in society, rather than hidden away from it." </blockquote> tag:metafilter.com,2015:site.151680Thu, 30 Jul 2015 09:42:14 -0800FizzFamous Fluid Equations Are Incomplete

It would be built not of rods and gears but <a href="http://paulromer.net/why-information-grows/">from a pattern</a> of interacting currents." (<a href="https://twitter.com/Noahpinion/status/624664545995264000">via</a>) <blockquote>Tao has emerged as one of the field's great bridge-builders. At the time of his Fields Medal, he had already made discoveries with more than 30 different collaborators. Since then, he has also become a prolific math blogger with a decidedly non-Gaussian ebullience: He celebrates the work of others, shares favorite tricks, documents his progress and delights at any corrections that follow in the comments. He has organized cooperative online efforts to work on problems. "Terry is what a great 21st-century mathematician looks like," [<a href="http://www.metafilter.com/user/21049">mefi's</a> <a href="http://projects.metafilter.com/4308/How-Not-To-Be-Wrong">own</a>] Jordan Ellenberg, a mathematician at the University of Wisconsin, Madison, who has collaborated with Tao, told me. He is "part of a network, always communicating, always connecting what he is doing with what other people are doing."</blockquote>

<a href="https://www.quantamagazine.org/20150721-famous-fluid-equations-are-incomplete/">A 115-year effort to bridge the particle and fluid descriptions of nature has led mathematicians to an unexpected answer</a> - "The evidence suggests that truer equations of fluid dynamics can be found in a little-known, relatively unheralded theory developed by the Dutch mathematician and physicist <a href="https://en.wikipedia.org/wiki/Diederik_Korteweg">Diederik Korteweg</a> in the early 1900s. And yet, for some gases, even the Korteweg equations fall short, and there is no fluid picture at all." tag:metafilter.com,2015:site.151640Wed, 29 Jul 2015 00:34:29 -0800kliuless
