We cannot say for sure what kind of a home Earth will offer in 2080, but averages made across thousands of model runs help paint a picture of what a 2 degrees Celsius warmer world would look like.
Shalosh B. Ekhad, the co-author of several papers in respected mathematics journals, has been known to prove with a single, succinct utterance theorems and identities that previously required pages of mathematical reasoning. Last year, when asked to evaluate a formula for the number of integer triangles with a given perimeter, Ekhad performed 37 calculations in…
From Michaela Pommells at Huffington Post: Let’s face it, race inequity may not be a deliberate goal of education policy and practice (or maybe it is) but neither is it accidental. The result is a whole lot of seemingly well-meaning people trying to evoke change in an education system that never intended to educate people…

Depending on certain factors, changing stances can actually help a candidate. But it also depends on what political party both voter and politician belong to. Author Metanexus Editors
Both high-valued diamond and low-prized graphite consist of exactly the same carbon atoms. The subtle but nevertheless important difference between the two materials is the geometrical configuration of their building blocks, with large consequences for their properties. There is no way any kind of material could be diamond and graphite at the same time. However,…
Sometimes, history really does seem to repeat itself. For the past 15 years, Peter Turchin, who studies population dynamics at the University of Connecticut in Storrs, has been taking the mathematical techniques that once allowed him to track predator–prey cycles in forest ecosystems, and applying them to human history. He has analyzed historical records on…
This was the year climate change vanished from the political agenda – and then suddenly reappeared, after Hurricane Sandy shook the country. It was just a few years ago that President Barack Obama flew to Copenhagen to rescue faltering climate treaty talks amid bipartisan calls for global warming action. But in 2012, there wasn’t a…
