Black hole illustration. Modern day mathematicians drew on modern mathematical tools that had not been developed before Ramanujan's death to prove that a mock modular form could be computed just as Ramanujan predicted. The result is a formula for mock modular forms that may prove useful to physicists who study black holes. (Credit: NASA, M. Weiss (Chandra X-Ray Center))

Dec. 17, 2012 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. A devout Hindu, Ramanujan said that his findings were divine, revealed to him in dreams by the...

## Olympic Games in Rio 2016: Mathematical formula can predict medal haul, including impact of home advantage

- 19 September 2012

TechAndComputer (Sep. 19, 2012) Team GB is only likely to clock up 46 medals in the Olympic Games in Rio in 2016, say researchers who used a mathematical formula three years ago to predict performance for London 2012, and came up with a medal haul of 63.

In the end, Team GB won 65 medals in London, so the prediction was only out by two.

The formula, published in the British Journal of Sports Medicine, is based on all cities and countries that have hosted the Olympic...

TechAndComputer (July 9, 2012) If a train is travelling a distance of 55 miles at 150mph, how long will it take to reach its destination? If the thought of having to answer this question makes you apprehensive, then you may have mathematics anxiety. A new study published July 9 in BioMed Central's open access journal Behavioral and Brain Functions reports that a number of school-age children suffer from mathematics anxiety and, although both genders' performance is likely to be...

## Knowledge of fractions and long division predicts long-term math success

TechAndComputer (June 15, 2012) From factory workers to Wall Street bankers, a reasonable proficiency in math is a crucial requirement for most well-paying jobs in a modern economy. Yet, over the past 30 years, mathematics achievement of U.S. high school students has remained stagnant -- and significantly behind many other countries, including China, Japan, Finland, the Netherlands and Canada.

## Study finds twist to the story of the number line: Number line is learned, not innate human intuition

TechAndComputer (Apr. 25, 2012) Tape measures. Rulers. Graphs. The gas gauge in your car, and the icon on your favorite digital device showing battery power. The number line and its cousins -- notations that map numbers onto space and often represent magnitude -- are everywhere. Most adults in industrialized societies are so fluent at using the concept, we hardly think about it. We don't stop to wonder: Is it "natural"? Is it cultural?

## Math teachers demonstrate a bias toward white male students, study finds

TechAndComputer (Apr. 16, 2012) While theories about race, gender, and math ability among high school students have long been debated, a recent study found that math teachers are, in fact, unjustifiably biased toward their white male students. This study was published in a new article released in the April 2012 issue of Gender & Society (GENDSOC), the official journal of the Sociologists for Women in Society, published by SAGE.

TechAndComputer (Mar. 22, 2012) Tapping out a beat may help children learn difficult fraction concepts, according to new findings due to be published in the journal Educational Studies in Mathematics. An innovative curriculum uses rhythm to teach fractions at a California school where students in a music-based program scored significantly higher on math tests than their peers who received regular instruction.

## Girls' verbal skills make them better at arithmetic, study finds

TechAndComputer (Feb. 23, 2012) While boys generally do better than girls in science and math, some studies have found that girls do better in arithmetic. A new study published in Psychological Science, a journal of the Association for Psychological Science, finds that the advantage comes from girls' superior verbal skills.

"People have always thought that males' advantage is in math and spatial skills, and girls' advantage is in language," says Xinlin Zhou of Beijing Normal...

## Puzzle play improves math skills

TechAndComputer (Feb. 17, 2012) An important context for figuring out problems through reasoning is puzzle play, say researchers at University of Chicago.

Psychologist Susan Levine and colleagues recently conducted a study that found 2-4 year-old children, who play with puzzles, have better spatial skills when assessed at 4 1/2 years of age.

After controlling for differences in parents' income, education and overall amount of parent language input, researchers say puzzle...

TechAndComputer (June 24, 2011) For years, it has been assumed that teachers -- specifically math teachers -- need to master the content they intend to teach. And the best way to do this is to take courses beyond that content.

Yet in a paper published June 23 in the Education Forum of the journal Science, Dr. Brent Davis of the University of Calgary says research does not support this common belief. There is little evidence that advanced...
