Thought experiment proposed to reconcile psychological versus thermodynamic arrows of time
Simulations uncover obstacle to harnessing laser-driven fusion
(Phys.org) —A once-promising approach for using next-generation, ultra-intense lasers to help deliver commercially viable fusion energy has been brought into serious question by new experimental results ...
Multifractals suggest the existence of an unknown physical mechanism on the Sun
The famous sunspots on the surface of the sun result from the dynamics of strong magnetic fields, and their numbers are an important indicator of the state of activity on the sun. At the Institute of Nuclear ...
In the eye of a chicken, a new state of matter comes into view
Along with eggs, soup and rubber toys, the list of the chicken's most lasting legacies may eventually include advanced materials such as self-organizing colloids, or optics that can transmit light with the ...
Mathematical equation could reduce traffic jams
(Phys.org) —New research has found traffic jams and accidents could be reduced by controlling the reaction times of robotic cars.
Increasing oil flow in the Keystone pipeline with electric fields
Researchers have shown that a strong electric field applied to a section of the Keystone pipeline can smooth oil flow and yield significant pump energy savings.
New model sheds light on 'flocking' behaviour
Understanding how turbulence can alter the shape and course of a flock of birds, a swarm of insects or even an algal bloom could help us to better predict their impact on the environment.
3-D imaging reveals hidden forces behind clogs, jams, avalanches, earthquakes
Pick up a handful of sand, and it flows through your fingers like a liquid. But when you walk on the beach, the sand supports your weight like a solid. What happens to the forces between the jumbled sand ...
Dancing beads on surface waves cluster in surprising ways
(Phys.org) —FOM researchers have discovered that objects floating on surface waves behave differently than expected. If a small number of floating objects is present on a water surface, these will drift ...
Try clapping your wet hands: A physics lesson from Virginia Tech engineers
Sunny Jung continues to redefine the views on the laws of physics, and in doing so, impacts the research on topics as varied as drug delivery methods to fuel efficiency.
Rethinking surface tension
(Phys.org) —If you've ever watched a drop of water form into a bead or a water strider scoot across a pond, you are familiar with a property of liquids called surface tension.
Mathematicians show how shallow water may help explain tsunami power
(Phys.org)—While wave watching is a favorite pastime of beachgoers, few notice what is happening in the shallowest water. A closer look by two University of Colorado Boulder applied mathematicians has led ...
When fluid dynamics mimic quantum mechanics
In the early days of quantum physics, in an attempt to explain the wavelike behavior of quantum particles, the French physicist Louis de Broglie proposed what he called a "pilot wave" theory. According to ...
High-speed camera captures dancing droplets for scientific 'photo album,' study (w/ Video)
The splash from rain hitting a windowpane or printer ink hitting paper all comes down to tiny droplets hitting a surface, and what each of those droplets does. Cornell University researchers have produced ...
