Blood flows could be more turbulent than previously expected
Blood flow in the human body is assumed to be mostly smooth and non-turbulent. Unstable and unsteady flow is linked to a variety of cardiovascular diseases including arteriosclerosis -- one of the leading causes of death worldwide. Now, Professor Björn Hof from the Institute of Science and Technology Austria, together with a team of international researchers has shown that our bloodstream is more turbulent than what has been previously thought.

Indeterminist physics for an open world
Classical physics is characterized by the equations describing the world. Yet our day-to-day experience is struck by this deterministic vision of the world. A physicist (UNIGE) has been analyzing the classical mathematical language used in modern physics. He has thrown light on a contradiction between the equations that explained the phenomena and the finite world. He suggests making changes to the mathematical language to allow randomness and indeterminism to become part of classical physics. (2020-01-07)

A new method for boosting the learning of mathematics
How can mathematics learning in primary school be facilitated? UNIGE has developed an intervention to promote the learning of math in school.

'I will do my very best!' Children who engage in positive self-talk about effort can boost their math achievement
Children who think poorly of themselves often underachieve in school. A new Dutch study tested whether a simple mental activity -- having children with low self-confidence say favorable, encouraging words to themselves -- could boost their achievement. The study found that children who engaged in this kind of self-talk improved their math performance when the talk focused on effort, not ability. (2019-12-17)

Researchers develop first mathematical proof for key law of turbulence in fluid mechanics
Turbulence is one of the least understood phenomena of the physical world. Long considered too hard to understand and predict mathematically, turbulence is the reason the Navier-Stokes equations, which describe how fluids flow, are so hard to solve that there is a million-dollar reward for anyone who can prove them mathematically. But now, University of Maryland mathematicians have broken through the barrier and developed the first rigorous mathematical proof for a fundamental law of turbulence. (2019-12-11)
