“Gold Tiger Eye Frost Crystals Ignite Fire Fiber Optics” Sunrise fires nature’s ice crystal
As well as marvels of nanotechnology like the “superlens” and the invisibility cloak, Roland Pease looks at optical computers and the trusty old laser.
Four hundred years ago, by combining a pair of simple lenses, Galileo revealed to the world a Universe far larger and far more interesting than had previously been imagined. Since then, telescopes and microscopes, and the study of the properties of light have contributed to many of the great breakthroughs of science.
But now light has become an instrument of science, able to heat, cool, cut and manipulate matter in marvelous ways.
In this edition of Discovery, Roland Pease sees how laser light creates the hottest and coldest materials on the planet, and how cells can be manouevred and dissected with beams of laser light.
“Invisibility cloak one step closer, scientists say”
The findings, to be released later this week in Nature and Science, were made by scientists at the University of California, Berkeley, led by Xiang Zhang. The research, which was funded in part by the U.S. Army Research Office and the National Science Foundation’s Nano-Scale Science and Engineering Center, could have broad applications, including for the military.
But the materials work in limited wavelengths, so they won’t be used to hide buildings from satellites, said Jason Valentine, who is a co-author of one of the papers.
“We are not actually cloaking anything,” Valentine told Reuters. While the Harry Potter series of books and films has made the idea of a personal “invisibility cloak” popular, he says, “I don’t think we have to worry about invisible people walking around any time soon. To be honest, we are just at the beginning of doing anything like that.”
“Army Eyes Invisibility Cloak”
According to Dr. Richard Hammond from the Army Research Office, the military is two or three years away from being able to manufacture devices using meta-materials that allow “unprecedented extreme control over the flow of light.” And not just that: in theory the materials could deflect radar and other sensors, too.
Famed physicist Dr. Michio Kaku discusses revolutionary research and experiments that could make this futuristic tech a reality.
Insane, invisible, rampaging scientists, a la Kevin Bacon in Hollow Man (pictured), can’t be far behind.
