Poachers in Africa killed 1,215 rhinos and 30,000 elephants last year, and that makes for an "unsustainable situation." A team at the University of Maryland's Institute for Advanced Computer Studies is now using "analytical models of how animals, poachers and rangers simultaneously move through space and time by combining high resolution satellite imagery with loads of big data--everything from moon phases, to weather, to previous poaching locations, to info from rhinos' satellite ankle trackers--and then applying our own algorithms." The aim is to better place rangers to thwart the poachers. The author, one of the researchers, states that "the real game changer is our use of unmanned aerial vehicles (UAVs) or drones." But of course Africa is too large to launch drones randomly, so that's where big data and analytical models are informing the rangers and gaining success in arresting poachers of these magnificent animals.

"A proof is like the mathematician's travelogue. Fermat gazed out of the mathematical window and spotted this mathematical peak in the distance: the statement that his equations do not have whole-number solutions. The challenge for subsequent generations of mathematicians was to find a pathway leading from the familiar territory that the mathematician has already navigated to this foreign new land. [It's] a bit like Frodo's adventures in Lord of the Rings," explained Marcus du Sautoy in a talk at Oxford University that writer Charlie Jane Anders attended and covered for io9. She notes that a proof is like a journey, "from the familiar to the new," and points to the archived video of the talk plus the Q&A session after it.

A notebook of Alan Turing's that hadn't been seen in public until recently will go up for auction in April. Turing made the notes, which foreshadow some of his later foundational work on computing and logic, while working to break the Enigma Code. Andrew Hodges, author of Alan Turing: The Enigma, says that "This notebook shines light on how, even when he was enmeshed in great world events, he remained committed to freethinking work on pure mathematics." Turing left the notebook to his close friend Robin Gandy, who added his own personal notes to the notebook and kept it until his death in 1995. Perhaps because of interest in Turing generated by The Imitation Game, the notebook is expected to sell for over US$1 million.

At the 2015 Joint Mathematics Meetings in San Antonio, Texas, Peking University professor Chuanming Zong made history as the first China-based professor to win an AMS award. This CCTV video clip features interviews with Dr. Zong about his work on how to fill space effectively with objects like tetrahedra, a problem that dates back 2300 years to the time of Aristotle. Zong and his research partner, Jeffrey Lagarias from the University of Michigan, won the 2015 Levi L. Conant award for their work expounding upon the history and ideas behind this problem (see the news release). The video also features AMS President David Vogan, who heralds Zong and Lagarias' work for its accessibility, particularly in an era when new mathematics research is often comprehensible to only a very small group of people. Zong concedes that finding the answer to Aristotle's question may still take centuries, but he is grateful for the support he has received for his efforts.

In this article, we learn about the discovery of a new curve by artist and mathematician Edmund Harriss. Harriss constructed his curve using a technique similar to the one used to create the "golden spiral," a curve drawn through, increasingly smaller squares in a rectangle that has been subdivided into a smaller similar square and a smaller rectangle, which is then subdivided in the same way, and so forth. Instead, Harriss used a rectangle that could be subdivided into a square and two smaller similar rectangles, each of which could be subdivided in the same way, ad infinitum. The "main" spiral is formed by drawing quarter circles from corner to adjacent corner of some of the squares in the rectangle. Other spirals branch out from this spiral in a fractal pattern.
Harriss was delighted to discover this spiral because it is both aesthetically pleasing and based on a very simple mathematical process. At the same time, he was motivated by the desire to draw attention to what he calls 'proportion systems': "rectangles that can be subdivided into only squares and similar rectangles." The golden spiral and the Harriss spiral are formed from just two of many such rectangles, each of which, in fact, have a ratio between their sides equal to an algebraic number! Harriss is currently trying to prove that "every algebraic number is the ratio of a rectangle belonging to a proportion system."

Southwestern University President and mathematics professor Ed Burger talks to radio host Jennifer Stayton about why "effective failure"—learning from one's mistakes—is critical to becoming better thinkers. Burger opines that thinking and education should be focused on the outcome of being better thinkers, and that failing is a requisite step to achieving that outcome, because "there's no greater teacher than one's own mistakes." As an example, he notes that the first draft of a piece of writing is always a failure, and even Shakespeare had first draft "failures" as intermediate steps to creating his masterpieces. Burger notes that in his own classroom, he does not shy away from highlighting students' mistakes, nor does he ascribe to the "everyone gets a trophy" philosophy. Instead, he seeks to create an environment where students intentionally take risks and make mistakes in their thinking, so that he can use the exploration of why a student is wrong to empower the student as the teacher, and so that the student can learn enough from her setbacks to truly earn that trophy.

Shinichi Mochizuki is a mathematician at the Research Institute of Mathematical Sciences in Kyoto (Japan). In 2012, he made headlines around the world when he posted a 500-page paper claiming a proof of the so-called ABC Conjecture, one of the central questions in modern number theory. Mochizuki is a well known and highly respected mathematician, so his claim to a proof has been taken very seriously by the mathematical community. However, because his paper has proven very difficult for others to understand, his proof has not been accepted as correct. The New Scientist article discusses a report that Mochizuki has posted on his web site, in which he describes the current status of attempts to verify his proof. "[Mochizuki] says that three researchers who studied it with his help have yet to find an error, but it will take a few more years for it to be fully confirmed," the New Scientist reports. According to Minhyong Kim, a mathematician at the University of Oxford who is quoted by the New Scientist, the proof needs to be presented in a form understandable to those who have not studied with Mochizuki. Kim said: "I sympathize with his sense of frustration but I also sympathize with other people who don't understand why he's not doing things in a more standard way."

The ancient art of origami has been "going through a renaissance over the past thirty years," notes Thomas Hull, a professor of mathematics at Western New England University. "New designs [are] being created at ever-increasing levels of complexity." In this article, Hull describes a little of what we have been learning about the mathematical rules that govern paper folding. "At heart, mathematics is about understanding the rules and patterns of the universe... In the case of origami, we need to look at the geometry of the crease pattern, where the lines intersect, what angles they form, and in what directions the creases fold." One such rule of origami models that fold flat is called Maekawa's Theorem: "at every vertex where creases intersect in a flat origami crease pattern, the difference between the number of mountain and valley creases is always two." (Image above: Valley fold, by Thomas Hull.)
Hull also describes a few of the applications that have resulted from developments in origami design. One such design is the Miura map fold or Miura-ori, an origami tessellation, used by Dr. Miura "as a way to deploy large solar panels into outer space." Dr. Hull is working with a team of researchers that is studying the Miura map as a mechanical device. Another application is the development of self-folding materials, including extremely thin sheets of gel that could be used to deliver toxic cancer drugs directly to tumors.
