Invisibility is the state of an object that cannot be seen. An object in this state is said to be invisible (literally, "not visible"). The term is often used in fantasy/science fiction, where objects are literally made unseeable by magical or technological means; however, its effects can also be seen in the real world, particularly in physics and perceptual psychology.
It may still be a while until we get our Harry Potter-like invisibility cloak, but researchers have managed, for the first time, to render a cylinder invisible to microwaves. Science, not magic Invisibility is a notion that fascinated humans for centuries or even millennia; it’s just one of those things which never gets old, regardless [...]
Cloaking has turned into a subject of great interest for scientists in the past decade, most likely because of its military potential. We’ve seen some exciting prototypes developed, from optical invisibility cloaks to temporal cloaks, and now French scientists at the University of Aix-Marseille have added a new member to the cloaking family, one that renders [...]
Worldwide, motor vehicles currently emit well over 900 million metric tons of CO2 each year, amounting to more than 15 percent of global fossil fuel CO2 releases. With this in mind, major automobile manufacturers have been investing massively in developing more fuel efficient power systems and lower emissions for the past few decades. We’ve seen a [...]
The much dreamed off invisibility cloak is just a few tiny steps away, after remarkable research in the field, many backed by military interests, have sparked some amazing advances. In the last few years alone, scientists have managed to successfully cloak various objects either using meta-materials that bent light around an object to conceal it or [...]
Cloaking used to be one of my favorite SciFi themes. James Bond supercars that would show up or disappear instantly at the flick of an alarm key, the hallow man, objects rendered completely invisible to the human eye and lost in the surroundings. I say used to be because spatial cloaking has transcended for some [...]
You’ve seen James Bond’s vanishing Aston Martin or Frodo’s Elven cloak, and probably always wished for your own means of becoming totally invisible. The are a lot of perks to such a technology (who here remembers Invisible Man movies?), and scientists from University of Dallas in Texas have managed to devise an invisibility cloak inspired by [...]
Photo by Firentzesca Recently, attempts to make “cloaking technology” possible have reached a great level, with major break throws. Among mentionable achievements, more notable are the work of Oleg Gadomsky, a Russian professor that managed to redirect light around objects and that of the people from the University of Maryland, who reported the successful cloaking [...]
