One consequence of the fundamental difference between flat surfaces and spherical surfaces, such as the Earth, is that any planar depiction of the Earth – such as a map on the wall, in an atlas, or on Google Maps – will necessarily have some distortions.

From the passes NHL players make to their teammates, to the shots they take to score, players in every position are constantly using geometry when playing the game. The lines, angles and curves on the ice are also examined. "Science of NHL Hockey" is a 10-part video series produced in partnership with NBC Learn and the National Hockey League.

Choose a number at random from scientific data. Think it's just as likely that it will start with a 9 as a 1? In many cases, you'd be wrong. The ages of volcanic calderas are one of those cases. Law-abiding citizens everywhere will be happy to know our planet also obeys Benford's Law, with the duration and size of volcanic eruptions showing the same sort of pattern.

More than 500 years ago, Leonardo da Vinci observed a particular relationship between the size of a tree’s trunk and the size of its branches. Specifically, the combined cross-sectional areas of a tree’s daughter branches are equal to the cross-sectional area of the mother branch. However, da Vinci didn’t know why tree branching followed this rule, and few explanations have been proposed since then. But now in a new study, physicist Christophe Eloy from Aix-Marseille University in Aix-en-Provence, France, has shown that this tree structure may be optimal for enabling trees to resist wind-induced stresses.

Back in 2006, Dan Christensen did something rather simple and got a surprisingly complex and interesting result. He took a whole bunch of polynomials with integer coefficients and drew their roots as points on the complex plane. The patterns were astounding!

Trees almost always grow so that the total thickness of their branches at a particular height is equal to the thickness of their trunks. Until now, no one has been able to explain why trees obey this rule, which Leonardo da Vinci first noticed.

We measure a digit ratio, abstract reasoning ability with the Raven Progressive Matrices task, and risk attitude with choice among lotteries. Low digit ratio in men is associated with higher risk taking and higher scores in abstract reasoning ability when a combined measure of risk aversion over different tasks is used.

Out of all these new ideas there is one that perhaps defies intuition more than all others: that space, when you zoom in on it, stops being a smooth and continuous whole and starts breaking up into little indivisible chunks of some kind. This idea is truly mind-boggling. When you think of little chunks you can't help but think of them as existing inside something else and this something is — well, continuous. Another visualisation is to imagine space becoming fuzzy at this fundamental scale. But what exactly does that mean? Fuzzy with respect to what? Our macroscopic intuition simply isn't equipped to deal with a non-continuous space. Maths is the only language in which to talk about this, but ordinary geometry won't do — we need a completely new model of space. Shahn Majid from Queen Mary, University of London, has developed such a model, based on something called non-commutative geometry. His work is a fascinating blend of abstract algebra, theoretical physics, philosophy and experiment. Plus went to see him to find out more.

Why the temperatures in the solar wind are almost the same in certain directions, and why different energy densities are practically identical, was until now not clear.
