Before going into hibernation at 01:36 CET on 15 November 2014, the Philae lander was able to conduct some work using power supplied by its primary battery. With its 10 instruments, the mini laboratory sniffed the atmosphere, drilled, hammered and studied Comet 67P/ Churyumov-Gerasimenko while over 500 million kilometres from Earth.

At the Far Ends of a New Universal Law

At the Far Ends of a New Universal Law | Physics as we know it. | Scoop.it

Systems of many interacting components — be they species, integers or subatomic particles — kept producing the same statistical curve, which had become known as the Tracy-Widom distribution. This puzzling curve seemed to be the complex cousin of the familiar bell curve, or Gaussian distribution, which represents the natural variation of independent random variables like the heights of students in a classroom or their test scores. Like the Gaussian, the Tracy-Widom distribution exhibits “universality,” a mysterious phenomenon in which diverse microscopic effects give rise to the same collective behavior. “The surprise is it’s as universal as it is,” said Tracy, a professor at the University of California, Davis.

Damien Thouvenin's curator insight, October 29, 10:15 AM

Un article intéressant : la courbe de fréquence d'apparition d'un état dans un réseau interconnectant de nombreux éléments (de nombreux systèmes complexes donc) ne suit pas la fameuse courbe de Gauss mais plutôt celle, asymétrique, de la distribution Tracy-Widom. Le modèle a été prouvé pour un certain nombre de cas mais on ne sait pas encore identifier les critères nécessaires et suffisants à son apparition mais cela semble corroborer les effets de seuil que l'on constate dans les réseaux massivement interconnectés.

How Information Theory Could Hold the Key to Quantifying Nature

How Information Theory Could Hold the Key to Quantifying Nature | Physics as we know it. | Scoop.it

The Western Ghats in India rise like a wall between the Arabian Sea and the heart of the subcontinent to the east. The 1,000-mile-long chain of coastal mountains is dense with lush rainforest and grasslands, and each year, clouds bearing monsoon rains blow in from the southwest and break against the mountains’ flanks, unloading water that helps make them hospitable to numerous spectacular and endangered species. The Western Ghats are one of the most biodiverse places on the planet. They were also the first testing ground of an unusual new theory in ecology that applies insights from physics to the study of the environment.

Traffic Ghost Hunting

Traffic Ghost Hunting | Physics as we know it. | Scoop.it

Few experiences on the road are more perplexing than phantom traffic jams. Most of us have experienced one: The vehicle ahead of you suddenly brakes, forcing you to brake, and making the driver behind you brake. But, soon afterward, you and the cars around you accelerate back to the original speed—and it becomes clear that there were no obstacles on the road, and apparently no cause for the slowdown.
Because traffic quickly resumes its original speed, phantom traffic jams usually don’t cause major delays. But neither are they just minor nuisances. They are hot spots for accidents because they force unexpected braking. And the unsteady driving they cause is not good for your car, causing wear and tear and poor gas mileage.

How bird flocks are like liquid helium

How bird flocks are like liquid helium | Physics as we know it. | Scoop.it

Mathematical model shows how hundreds of starlings coordinate their movements in flight.

A flock of starlings flies as one, a spectacular display in which each bird flits about as if in a well-choreographed dance. Everyone seems to know exactly when and where to turn. Now, for the first time, researchers have measured how that knowledge moves through the flock—a behavior that mirrors certain quantum phenomena of liquid helium.
