Globalization certainly has its ups: new markets, free trade, travel or economic growth (especially for developing nations). It’s this latter aspect of globalization that might be the dominant factor that’s wiping out languages from the face of the world, according to a study by researchers at University of Cambridge. …

How one single sheepdog herds a flock of one hundred – mystery solved

sheepdog

Researchers at Swansea University, UK and Uppsala University in Sweden built a mathematical model that explains how one single sheepdog can round up herds made of up to 100 sheep. Their conclusion suggests that the dog needs only to follow two simple mathematical rules. …

The road to happiness is paved with many surprises

happiness

Sometimes, we go through situations thinking when we reach the end of the road the outcome will feel gloom. But sometimes, the exact opposite happens and we’re flooded with absolute joy, the kind of which we couldn’t have experienced were we to expect that outcome. In a word, this is called surprise. …

If you fold an A4 sheet of paper 103 times its thickness will roughly be the size of the Universe

The folding limiting equation Britney found: L is the minimum possible length of the material, t is material thickness, and n is the number of folds possible in one direction.

Whaaaat? It’s just a matter of math, really. Fold an A4 once and it will be twice as thick, fold it again and it will be four times as thick as it initially was. Turns out, according to Dr Karl Kruszelnicki, if you do this 103 times the sheet’s thickness will be larger than the observable Universe: 93 billion light-years.  To do…

University of Stuttgart’s Institute for Computational Design (ICD) is a state of the art research facility that seeks to solve complex structural problems by mimicking nature. Every year, the institute demonstrates how natural biological constructions can be used to solve design problems by building a new research wing. The results are nothing short of breath taking. This year for instance, ICD…

Invisibility cloak could help protect cities from earthquakes

invisible

French researchers say they are close to developing seismic ‘invisibility cloaks’ which would cancel out potentially hazardous earthquake shockwaves, protecting key buildings or even entire cities. Nuclear power plants especially, and potentially entire cities could be cloaked using this technology – if the researchers’ theories are true (which seems highly likely). They believe that by drilling boreholes in a precise pattern into…

It’s long been supposed that monkeys are capable of mental arithmetics, but it was only recently that this was proven for a fact by neuroscientists at the Margaret Livingstone of Harvard Medical School in Boston. The researchers taught three rhesus macaques to identify symbols representing the numbers zero to 25, then when given the choice between two panels, one depicting…

Children who use their hands to gesture during a math lesson gain a much deeper understanding of the concepts and methods discussed, according to new research from University of Chicago’s Department of Psychology. It’s already a pretty much accepted fact that gesturing accentuates children learning – it was already established by several studies that gestures help children learn – and…
