3:30 PM | Retractions appear in case of former Kansas water scientist rebuked for misconduct
Back in December, the University of Kansas issued a public censure of a former water researcher who, the school says, engaged in a pattern of plagiarism and other shoddy publishing practices. Marios Sophocleous, who’d held the position of senior scientist at the Kansas Geological Survey: has been found to have engaged in scholarly misconduct, relating […]

3:30 PM | "Knowing Alongside"
I was briefly observing a classroom yesterday where some students were discussing what they thought "congruent" meant. In particular, they were trying to determine if two figures were congruent....which led to some theory building about when figures could be considered congruent or not congruent, more generally.One student had constructed (what I thought to be) a very interesting theory. His theory was (and I'm paraphrasing [...]

3:30 PM | Active Subspace: Towards Scalable Low-Rank Learning - implementation -
Active Subspace: Towards Scalable Low-Rank Learning, Guangcan Liu and Shuicheng YanWe address the scalability issues in low-rank matrix learning problems. Usually, these problems resort to solving nuclear norm regularized optimization problems (NNROPs), which often suffer from high computational complexities if based on existing solvers, especially under large-scale settings. Based on the fact that the optimal solution matrix to an NNROP is often low-rank, we revisit the classic mechanism of […]

3:10 PM | Maria Droujkova - Make Math your Own
This morning I listened to a recording of Maria Droujkova giving a keynote address at the Learning Revolution Conference Online. The title of her talk was "From adventurous learning to disruptive innovations: brave design in mathematics education." Here's her description of the talk: Robert Lang is building a space telescope as long as the island of Manhattan. His out-of-the-box origami play helped to figure out how to fold the telescope into a rocket’s tiny storage box. Vi Hart is a […]

3:00 PM | Teaching, Conceptualizing, Common Core
As much as I try to avoid the primary/secondary education debates, I'd feel remiss if I didn't pass along two of the pieces from this morning's Web:1) California teacher Fawn Nguyen interviewed by Cathy O'Neil on Common Core:http://mathbabe.org/2014/04/23/interview-with-a-high-school-math-teacher-on-the-common-core/2) Grant Wiggins on "conceptual understanding" (longread +comments):http://grantwiggins.wordpress.com/2014/04/23/conceptual-understanding-in-mathematics/Fascinating (to me) how […]

2:52 PM | Hail to the Bard! 450 Years of William Shakespeare
There are plenty of old writers, poets, and playwrights whose works have stood the test of time—pieces that literary gurus still analyze and quote, and call “classics.” But few have remained so prominent that they have been a common household name for over 400 years. This year is the 450th anniversary of his birth. 450 [...]

2:45 PM | New Books Using Wolfram Technologies
Mathematica and Wolfram|Alpha are powerful technologies for deepening students’ and researchers’ understanding of complex topics in math and science. These recently published books incorporate engaging Mathematica and Wolfram|Alpha examples and code into texts written for undergraduates, graduate students, and researchers. Composite Materials in Piping Applications: Design, Analysis and Optimization of Subsea and Onshore Pipelines Dimitrios [...]

2:28 PM | Birth and death of zipper combinators (I)
Because zipper logic is a graph rewriting system which does not use variable names, just like GLC and chemlabda,  it needs ways to multiply, distribute or kill  things. See  Chemlambda, universality and self-multiplication  for multiplication, distribution or propagation phenomena. In this post we shall see how zipper combinators die or are born, depending on the sense […]

Folded DNA makes a 3-D nanostructure that is embedded with lipid molecules. Courtesy Wyss. The lipid molecules attached to the DNA nanostructure act as handles to direct the assembly of a lipid bilayer around the structure. Courtesy Wyss. The end product is a totally lipid bilayer nanostructure that cloaks the DNA nanostructure from an organism's immune system. Courtesy Wyss. Enveloped viruses (bottom) coat themselves with lipids.

A group of researchers in Tokyo has lost their 2013 article in the Journal of Crystal Growth over commercial interests — which don’t appear to be their own. We’ll explain. The article, “Interactions between planar defects in bulk 3C-SiC,” came from a team consisting of a researcher at Keio University and scientists at two companies, […]

1:30 PM | Peirce’s 1870 “Logic Of Relatives” • Comment 10.9
The use of the concepts of identity and teridentity is not to identify a thing-in-itself with itself, much less twice or thrice over — there is no need and therefore no utility in that. I can imagine Peirce asking, on Kantian … Continue reading →

1:22 PM | Dangerous graphs
Is there a worst-possible paradox and if so what is it? In this post I’ll discuss an open question about graphs, whose answer, if we could answer it, might tell us what is the worst-possible paradox. Most people have come across the Liar Paradox at some point or other, whether in an academic journal, or [...]

12:07 PM | Interalia: From strings to sculpture
Interalia is a show by Turner Prize winning artist Grenville Davey and theoretical physicist David Berman. When I went to see Interalia yesterday afternoon I managed to walk past the gallery twice, before an extremely helpful passer by finally pointed me in the (obvious) right direction. This worried me: if I can't even find the gallery, will I be equally unperceptive when it […]
