As you know the highest mountain in our Solar System is on the planet Mars which is called Olympus Mons. But today we will introduce you top 10 tallest mountains according to their heights.
Scientists in France are working on an invisibility cloak for heat and have reported their research in a recent issue of Optics Express.
The technology could be used for military purposes to hide soliders from infrared detectors, but it could also work to thermally isolate circuits in computer chips, which would keep them cool. The team, lead by Sebastien Guenneau of the University of Aix-Marseille and colleagues at the French national research council, devised a mathematical model showing that a set of concentric rings, each one made of a material with differing diffusivity could cloak heat energy. Metal, for example, diffuses heat very well, while plastic doesn’t. By alternating such materials, the heat flowed around the central region, essentially making it invisible. An infrared camera wouldn’t pick it up because there would be no temperature difference between that region and its surroundings. As said Sebastien Guenneau the underlying idea is to guide heat around the region which you’d like to protect from thermal flux. A key finding in this research is that the team realized cloaking heat would not require exotic, manmade materials, known as metamaterials, typically used to cloak objects from other kinds of light waves or even sound waves. That’s good news for this kind of cloaking because it can use standard materials already available. The next step is to actually fabricate a device, thus far the work has been in the area of mathematical modeling. It will take some work to find the materials that work best.
