Physics Students a Maze With Leidenfrost Effect

Physics Students a Maze With Leidenfrost Effect

Reuters (Nov. 29, 2013) — An aluminum maze which demonstrates the so-called 'Leidenfrost effect' could help inspire the development of a new wave of non-electric thermostats. In physics, the 'Leidenfrost effect" allows water droplets to travel upwards on heated surfaces, a phenomenon scientists in the UK believe could become the basis of new engineering systems. Jim Drury went to see it in action.

Spain: The Battle Over Water

Spain: The Battle Over Water

Deutsche Welle (Aug. 21, 2013) — As a result of the economic crisis, many municipalities in Spain have sold their public water utilities to private companies. Now some local communities are finding out that the water supply networks are no longer being maintained properly and that water quality is on the decline. By the end of the year, about 60 percent of water utility management will be partly or entirely in private hands, making Spain the frontrunner in water privatization within Europe. Some experts are already calling it a "water bubble, and communities that are still trying to sell their water utilities are no longer able to obtain top prices. Now some communities are trying to regain public control over their water supply.

The Physics Behind Oracle's America's Cup Victory

FORA.tv (Oct. 4, 2013) — The Physics Behind Oracle's America's Cup Victory California Academy of Sciences - African Hall Why go fast? Compared to moving slowly, the advantages seem obvious: find food first, forage more widely, and escape more rapidly! But, in the water, being speedier incurs huge energetic costs, with moving a little bit faster skyrocketing the amount of fuel you need. This trade-off between speed and energy propels the evolutionary race for fish, robots, or sailboats: you have to find ways to go faster with ever-greater efficiency. Over generations, the evolutionary race can produce biological and engineering surprises: distantly related fish and boat hulls that have similar streamlined shapes, materials and construction techniques that manage to both stiffen and lighten bodies and hulls, specialization of propulsive systems, and constraints on making turns and tight maneuvers. While the evolutionary processes employed by nature and engineers are similar, there are important differences in how fish or boats are built. For both kinds of designers, the laws of evolution and physics interact to create and constrain the drive for speed. Dr Long will discuss how robotics research lab studies fast fish! A book signing will follow the talk for Dr. Long's latest book titled Darwin's Devices: What Evolving Robots Can Teach Us About the History of Life and the Future of Technology.
