They include "coffee rings" from dried coffee droplets, soup stains on the dining table, and the patterns salted snowmelt lays down on the pavement. Solvents leave a variety of residues as they evaporate from suspensions, including single rings, periodic bands, shapes resembling spider webs, and even wide uniform films assembled from arrested particles.

In order to achieve this, she programmed a mathematical tool in which all stations had to be visited at least once and where all connections had to be ridden at least once as well. Her tool eventually provided a travel plan which, despite a heavy storm, in practice would be 1 hour and 57 minutes faster than the previous record. At every station she took a picture as proof. The record attempt has been submitted to Guinness World Records, for an official mention.

It transpired that this is not a common combination and I then went on to do my PhD at Loughborough University in Leicestershire in the United Kingdom on mathematical application solving engineering problems. Both these choices proved fruitful in my career, which brought me to Wits University in 1997," says Professor Montaz Ali.

Mathematics Wed, 08 Oct 2014 09:40:01 ESTnews331977351Fluid mechanics suggests alternative to quantum orthodoxyThe central mystery of quantum mechanics is that small chunks of matter sometimes seem to behave like particles, sometimes like waves. For most of the past century, the prevailing explanation of this conundrum has been what's called the "Copenhagen interpretation"—which holds that, in some sense, a single particle really is a wave, smeared out across the universe, that collapses into a determinate location only when observed.

This is due to a higher presence of dense roots and organic matter in the soil. Since water is a limited resource in many dry ecosystems, such as semi-arid environments and semi-deserts, there is a benefit to vegetation to adapt by forming closer networks with little space between plants.

General Physics Wed, 10 Jul 2013 13:00:05 ESTnews292678608Researchers explain magnetic field misbehavior in solar flaresWhen a solar flare filled with charged particles erupts from the sun, its magnetic fields sometime break a widely accepted rule of physics. The flux-freezing theorem dictates that the magnetic lines of force should flow away in lock-step with the particles, whole and unbroken. Instead, the lines sometimes break apart and quickly reconnect in a way that has mystified astrophysicists.

This necessitates collecting energy from ambient sources including wind, solar, and geothermal power, and converting it into appropriate forms for distributing electricity. While it is possible for this electric power to be distributed efficiently, conversion is necessary for use in automobiles and large-scale storage is problematic.
