Thanks to Alex Bellos and Tash Reith-Banks for their July 30, 2015 posting on the Guardian science blog network for pointing towards the Bridges 2015 conference,
The Bridges Conference is an annual event that explores the connections between art and mathematics. Here is a selection of the work being exhibited this year, from a Pi pie which vibrates the number pi onto your hand to delicate paper structures demonstrating number sequences. This year’s conference runs until Sunday in Baltimore (Maryland, US).
To whet your appetite, here’s the Pi pie (from the Bellos/Reith-Banks posting),
Pi Pie by Evan Daniel Smith Arduino, vibration motors, tinted silicone, pie tin “This pie buzzes the number pi onto your hand. I typed pi from memory into a computer while using a program I wrote to record it and send it to motors in the pie. The placement of the vibrations on the five fingers uses the structure of the Japanese soroban abacus, and bears a resemblance to Asian hand mnemonics.” Photograph: The Bridges Organisation

The Bridges Baltimore Family Day on Friday afternoon July 31 will be open to the Public to visit the BB Art Exhibition and participate in a series of events such as BB Movie Festival, and a series of workshops.
I believe the conference is being held at the University of Baltimore. Presumably, that’s where you’ll find the art show, etc.
The Wilkinson Prize is not meant to recognize a nice, shiny new algorithm, rather it’s meant for the implementation phase and, as anyone who have ever been involved in that phase of a project can tell you, that phase is often sadly neglected. So, bravo for the Wilkinson Prize!
From the March 27, 2014 Numerical Algorithms Group (NAG) news release, here’s a brief history of the Wilkinson Prize,
NAG, NPL [UK National Physical Laboratory] and Argonne [US Dept. of Energy, Argonne National Laboratory] are committed to encouraging innovative, insightful and original work in numerical software in the same way that Wilkinson inspired many throughout his career. Wilkinson worked on the Automatic Computing Engine (ACE) while at NPL and later authored numerous papers on his speciality, numerical analysis. He also authored many of the routines for matrix computation in the early marks of the NAG Library.
The most recent Wilkinson Prize was awarded in 2011 to Andreas Waechter and Carl D. Laird for IPOPT. Commenting on winning the Wilkinson Prize Carl D. Laird, Associate Professor at the School of Chemical Engineering, Purdue University, said “I love writing software, and working with Andreas on IPOPT was a highlight of my career. From the beginning, our goal was to produce great software that would be used by other researchers and provide solutions to real engineering and scientific problems.
The Wilkinson Prize is one of the few awards that recognises the importance of implementation – that you need more than a great algorithm to produce high-impact numerical software. It rewards the tremendous effort required to ensure reliability, efficiency, and usability of the software.
1995: Chris Bischof and Alan Carle for ADIFOR 2.0.
1991: Linda Petzold for DASSL.
The prize will be awarded to the authors of an outstanding piece of numerical software, or to individuals who have made an outstanding contribution to an existing piece of numerical software. In the latter case applicants must clearly be able to distinguish their personal contribution and to have that contribution authenticated, and the submission must be written in terms of that personal contribution and not of the software as a whole. To encourage researchers in the earlier stages of their career all applicants must be at most 40 years of age on January 1, 2014.
Rules for Submission
Each entry must contain the following:
Software written in a widely available high-level programming language.

Two artists ,Yann Pineill and Nicolas Lefaucheux, associated with Parachutes, a video production and graphic design studio located in Paris, France, ,have produced a video demonstrating this quote from Bertrand Russell, which is in the opening frame,
“Mathematics, rightly viewed, possesses not only truth, but supreme beauty — a beauty cold and austere, without the gorgeous trappings of painting or music.” — Bertrand Russell
Publicizing an unpublished academic paper, which makes the claim that a series of math games, Monkey Tales, are more effective than classroom exercises for teaching maths while trumpeting a series of unsubstantiated statistics, seems a little questionable. The paper featured in a July 8, 2013 news item on ScienceDaily is less like an academic piece and more like an undercover sales document,
To measure the effectiveness of Monkey Tales, a study was carried out with 88 second grade pupils divided into three groups. One group was asked to play the game for a period of three weeks while the second group had to solve similar math exercises on paper and a third group received no assignment. The math performance of the children was measured using an electronic arithmetic test before and after the test period. When results were compared, the children who had played the game provided significantly more correct answers: 6% more than before, compared to only 4% for the group that made traditional exercises and 2% for the control group. In addition, both the group that played the game and that which did the exercises were able to solve the test 30% faster while the group without assignment was only 10% faster.
Ordinarily, this excerpt wouldn’t be a big problem since one would have the opportunity to read the paper and analyse the methodology by asking questions such as this, how were the students chosen? Were the students with higher grades given the game? There’s another issue, percentages can be misleading when one doesn’t have the numbers, e.g., if there’s an increase from one to two, it’s perfectly valid to claim a 100% increase even if it is misleading. Finally, how were they able to measure speed? The control group, i.e., group without assignment, was 10% faster than whom?
Serious or educational games are becoming increasingly important. Market research company iDate estimates that the global turnover was €2.3 billion in 2012 and expects it to rise to €6.6 billion in 2015.* A first important sector in which serious games are being used, is defence. The U.S. Army, for example, uses games to attract recruits and to teach various skills, from tactical combat training to ways of communicating with local people. Serious games are also increasingly used in companies and organizations to train staff. The Flemish company U&I Learning, for example, developed games for Audi in Vorst to teach personnel the safety instructions, for Carrefour to teach student employees how to operate the check-out system and for DHL to optimise the loading and unloading of air freight containers.
Reservations about the study aside, Monkey Tales (for PC only) looks quite charming.

In addition to a demo which can be downloaded, the site’s FAQs (Frequently Asked Questions) provides some information about the games’ backers and the games,
Who created Monkey Tales?
Developed by European schoolbook publisher Die Keure and award winning game developer Larian Studios, Monkey Tales is based on years of research and was developed with the active participation of teachers, schools, universities and educational method-makers.
What does years of research mean ?
Exactly that. The technology behind Monkey Tales has been in development for over 4 years, and has been field tested with over 30 000 children and across several schools, with very active engagement from both teachers and educational method-makers. Additionally, a two years research project is underway in which the universities of Ghent & Leuven are participating to measure the efficiency of the methods used within Monkey Tales.
What is the educational goal behind Monkey Tales?
Monkey Tales’ aim is not to instruct, that’s what teachers and schools are for. Instead it aims to help children rehearse and improve skills they should have, by motivating them to do drill exercises with increasing time pressure.
Because the abilities of children are very diverse, the algorithm behind the game first tries to establish where a child is on the learning curve, and then stimulates the child to make progress. This way frustration is avoided, and the child makes progress without realizing that it’s being pushed forward.
There’s a demonstrable effect that playing the game helps mastery of arithmetic. Parents can experience this themselves by trying out the games.
What can my child learn from Monkey Tales?
Currently there are five games available, covering grades 2 to 6, covering the field of mathematics in line with state standards (Common Core Standards and the 2009 DoDEA standards). Future games in the series will cover language and science.
What’s special about Monkey Tales?
A key feature of Monkey Tales is its unique algorithm that allows the game to automatically adapt to the level of children so that they feel comfortable with their ability to complete the exercises, removing any stress they might feel. From there, the game then presents progressively more difficult exercises, all the time monitoring how the child is performing and adapting if necessary. One of the most remarkable achievements of Monkey Tales is its ability to put children under time pressure to complete exercises without them complaining about it!
Hopefully this Monkey Tales study or a new study will be published and a news release, which by its nature, offers skimpy information won’t provoke any doubts about the validity of the work.
“We find positive and substantial longer-run impacts of double-dose algebra on college entrance exam scores, high school graduation rates and college enrollment rates, suggesting that the policy had significant benefits that were not easily observable in the first couple of years of its existence,” wrote the article’s authors.
The Mar. 21, 2013 news release on EurekAlert which includes the preceding quote recounts an extraordinary story about an approach to teaching algebra that was not enthusiastically adopted at first but first some reason administrators and teachers persisted with it. Chelsey Leu’s Mar. 21, 2013 article (which originated the news release) for UChicago (University of Chicago) News (Note: Links have been removed),
Martin Gartzman sat in his dentist’s waiting room last fall when he read a study in Education Next that nearly brought him to tears.
A decade ago, in his former position as chief math and science officer for Chicago Public Schools [CPS], Gartzman spearheaded an attempt to decrease ninth-grade algebra failure rates, an issue he calls “an incredibly vexing problem.” His idea was to provide extra time for struggling students by having them take two consecutive periods of algebra.
In high schools, ninth-grade algebra is typically the class with the highest failure rate. This presents a barrier to graduation, because high schools usually require three to four years of math to graduate.
Students have about a 20 percent chance of passing the next math level if they don’t first pass algebra, Gartzman said, versus 80 percent for those who do pass. The data are clear: If students fail ninth-grade algebra, the likelihood of passing later years of math, and ultimately of graduating, is slim
Gartzman’s work to decrease algebra failure rates at CPS was motivated by a study of Melissa Roderick, the Hermon Dunlap Smith Professor at UChicago’s School of Social Service Administration. The study emphasized the importance of keeping students academically on track in their freshman year to increase the graduation rate.
Some administrators and teachers resisted the new policy. Teachers called these sessions “double-period hell” because they gathered, in one class, the most unmotivated students who had the biggest problems with math.
Principals and counselors sometimes saw the double periods as punishment for the students, depriving them of courses they may have enjoyed taking and replacing them with courses they disliked.
It seemed to Gartzman that double-period students were learning more math, though he had no supporting data. He gauged students’ progress by class grades, not by standardized tests. The CPS educators had no way of fully assessing their double-period idea. All they knew was that failure rates didn’t budge.
Unfortunately, Leu does not explain why the administrators and teachers continued with the program but it’s a good thing they did (Note: Links have been removed),
“Double-dosing had an immediate impact on student performance in algebra, increasing the proportion of students earning at least a B by 9.4 percentage points, or more than 65 percent,” noted the Education Next article. Although ninth-grade algebra passing rates remained mostly unaffected, “The mean GPA across all math courses taken after freshman year increased by 0.14 grade points on a 4.0 scale.”
They also found significantly increased graduation rates. The researchers concluded on an encouraging note: “Although the intervention was not particularly effective for the average affected student, the fact that it improved high school graduation and college enrollment rates for even a subset of low-performing and at-risk students is extraordinarily promising when targeted at the appropriate students.” [emphasis mine]
Gartzman recalled that reading the article “was mind-blowing for me. I had no idea that the researchers were continuing to study these kids.”
The study had followed a set of students from eighth grade through graduation, while Gartzman’s team could only follow them for a year after the program began. The improvements appeared five years after launching double-dose algebra, hiding them from the CPS team, which had focused on short-term student performance. [emphasis mine]
Gartzman stressed the importance of education policy research. “Nomi and Allensworth did some really sophisticated modeling that only researchers could do, that school districts really can’t do. It validates school districts all over the country who had been investing in double-period strategies.”
I’m not sure I understand the numbers very well (maybe I need a double-dose of numbers). The 9.4% increase for students earning a B sounds good but a mean increase of 0.14 in grade points doesn’t sound as impressive. As for the bit about the program being “not particularly effective for the average affected student,” what kind of student is helped by this program? As for the improvements being seen five years after the program launch. does this mean that students in the program showed improvement five years later (in first year university) or that researchers weren’t able to effectively measure any impact in the grade nine classroom until five years after the program began?
Regardless, it seems there is an improvement and having suffered through my share algebra classes, I applaud the educators for finding a way to help some students, if not all.
1920, the year mathematician Srinivasa Ramanujan died, is also the year he left behind mathematical formulas that may help unlock the secrets of black holes (from the Dec. 11, 2012 posting by Carol Clark for Emory University’s e-science commons blog),
“No one was talking about black holes back in the 1920s when Ramanujan first came up with mock modular forms, and yet, his work may unlock secrets about them,” Ono [Emory University mathematician Ken Ono] says.
Expansion of modular forms is one of the fundamental tools for computing the entropy of a modular black hole. Some black holes, however, are not modular, but the new formula based on Ramanujan’s vision may allow physicists to compute their entropy as though they were.
Ramanujan was on his death bed (at the age of 32) when he devised his last formulas (from the Clark posting),
Accessed from http://esciencecommons.blogspot.ca/2012/12/math-formula-gives-new-glimpse-into.html
… A devout Hindu, Ramanujan said that his findings were divine, revealed to him in dreams by the goddess Namagiri.
While on his death-bed in 1920, Ramanujan wrote a letter to his mentor, English mathematician G. H. Hardy. The letter described several new functions that behaved differently from known theta functions, or modular forms, and yet closely mimicked them. Ramanujan conjectured that his mock modular forms corresponded to the ordinary modular forms earlier identified by Carl Jacobi, and that both would wind up with similar outputs for roots of 1.
No one at the time understood what Ramanujan was talking about. “It wasn’t until 2002, through the work of Sander Zwegers, that we had a description of the functions that Ramanujan was writing about in 1920,” Ono says.
This year (2012) a number of special events have been held to commemorate Ramanujan’s accomplishments (Note: I have removed links), from the Clark posting,
December 22  marks the 125th anniversary of the birth of Srinivasa Ramanujan, an Indian mathematician renowned for somehow intuiting extraordinary numerical patterns and connections without the use of proofs or modern mathematical tools. ..
“I wanted to do something special, in the spirit of Ramanujan, to mark the anniversary,” says Emory mathematician Ken Ono. “It’s fascinating to me to explore his writings and imagine how his brain may have worked. It’s like being a mathematical anthropologist.”
Ono, a number theorist whose work has previously uncovered hidden meanings in the notebooks of Ramanujan, set to work on the 125th-anniversary project with two colleagues and former students: Amanda Folsom, from Yale, and Rob Rhoades, from Stanford.
The result is a formula for mock modular forms that may prove useful to physicists who study black holes. The work, which Ono recently presented at the Ramanujan 125 conference at the University of Florida, also solves one of the greatest puzzles left behind by the enigmatic Indian genius.
Here’s a trailer for the forthcoming movie (a docu-drama) about Ramanujan, from the Clark posting,
Here’s a description of Ramanujan from Wikipedia, which gives some insight into the nature of his genius (Note: I have removed links and a footnote),
Srinivasa Ramanujan FRS (…) (22 December 1887 – 26 April 1920) was an Indian mathematician and autodidact who, with almost no formal training in pure mathematics, made extraordinary contributions to mathematical analysis, number theory, infinite series, and continued fractions. Living in India with no access to the larger mathematical community, which was centered in Europe at the time, Ramanujan developed his own mathematical research in isolation. As a result, he sometimes rediscovered known theorems in addition to producing new work. Ramanujan was said to be a natural genius by the English mathematician G.H. Hardy, in the same league as mathematicians like Euler and Gauss.
There is a little more to Ono’s latest work concerning Ramanujan’s deathbed math functions (from the Clark posting),
After coming up with the formula for computing a mock modular form, Ono wanted to put some icing on the cake for the 125th-anniversary celebration. He and Emory graduate students Michael Griffin and Larry Rolen revisited the paragraph in Ramanujan’s last letter that gave a vague description for how he arrived at the functions. That one paragraph has inspired hundreds of papers by mathematicians, who have pondered its hidden meaning for eight decades.
“So much of what Ramanujan offers comes from mysterious words and strange formulas that seem to defy mathematical sense,” Ono says. “Although we had a definition from 2002 for Ramanujan’s functions, it was still unclear how it related to Ramanujan’s awkward and imprecise definition.”
Ono and his students finally saw the meaning behind the puzzling paragraph, and a way to link it to the modern definition. “We developed a theorem that shows that the bizarre methodology he used to construct his examples is correct,” Ono says. “For the first time, we can prove that the exotic functions that Ramanujan conjured in his death-bed letter behave exactly as he said they would, in every case.”
Ono is now on a mathematicians’ tour in India (from the Clark posting),
Ono will spend much of December in India, taking overnight trains to Mysore, Bangalore, Chennai and New Dehli, as part of a group of distinguished mathematicians giving talks about Ramanujan in the lead-up to the anniversary date.
“Ramanujan is a hero in India so it’s kind of like a math rock tour,” Ono says, adding, “I’m his biggest fan. My professional life is inescapably intertwined with Ramanujan. Many of the mathematical objects that I think about so profoundly were anticipated by him. I’m so glad that he existed.”
Between this and the series developed by Alex Bellos about mathematics in Japan (my Oct. 17, 2012 posting), it seems that attention is turning eastward where the study and development of mathematics is concerned. H/T to EurekAlert’s Dec. 17, 2012 news release and do read Clark’s article if you want more information about Ono and Ramanujan.

Mathematics professor at Australia’s Queensland University of Technology (QUT), Graeme Pettet provides a fascinating perspective on skin and bone, from the April 23, 2012 news item by Alita Pashley on physorg.com,
Professor Graeme Pettet, a mathematician from QUT’s Institute of Health Biomedical Innovation (IHBI), said maths could be used to better understand the structure of skin and bones and their response to healing techniques, which will eventually lead to better therapeutic innovations.
“Mathematics is the language of any science so if there are spatial or temporal variations of any kind then you can describe it mathematically,” he said.
“Skin is very difficult to describe. It’s very messy and very complicated. In fact most of the descriptions that engineers and biologists use are schematic stories (diagrams),” he said.
“Once we understand the structure (of the skin) and how it develops we can begin to analyze how that development impacts upon healing in the skin and maybe also diseases of the skin.”
Professor Pettet said his research would, for the first time, formalise the theories about the way cells interact when healing.
Professor Pettet is also working on applying similar techniques to figure out how to show how small, localised damage at the site of bone fractures can impact on healing.
