In 1975, Yoshiki Kuramoto introduced a simple model to describe the collective dynamics of a set of interacting oscillators. In the model, each oscillator has a natural frequency, and is coupled equally to all other oscillators.
How do animals move through their environment as they search for resources, or try to satisfy other natural goals? Over the past two decades, researchers have examined this question using real world data for organisms such as albatross, marine predators and bees, often finding a pattern of many short or mid-scale movements punctuated by occasional […]

Tectonic movements create stress within the Earth’s crust, which gets released in sudden earthquakes, but also in less dramatic slow slip events. Such events are sometimes accompanied by so-called non-volcanic tremors – weak seismic signals of extended duration along major faults.
In Southern California, Japan, Indonesia or other areas around the world prone to earthquakes, people at risk face vast uncertainty about when, where, and how strong the next one will be.
Early in the 20th century, experts tried to forecast the weather by noting current conditions, patterns of winds, temperatures and air pressures, and looking into historical records to find previous moments when similar conditions prevailed. Looking a few days forward in the records, they could then make predictions by assuming the atmosphere would evolve as […]
The stable fixed points of a dynamical system attract obvious interest as potential resting points, or final states. Without continued forcing, for example, a physical pendulum will ultimately end up hanging motionless in the downward position.
The jet stream is a band of air that flows around the Earth at high-altitude, moving West to East in mid-latitude regions. This so-called “zonal” flow typically has cyclones and anticyclones embedded within it, which last for a few days.

Following the financial crisis of 2007-2008, governments and financial regulators all over the globe pledged to reduce risk in the financial system. Many have raised capital requirements on banks, while others have tried to force financial institutions to be less opaque in communications with their clients.
