(Phys.org) -- In the real world of so called “normal” materials, people expect certain things to occur as a result of certain actions. Covering an object with a cloak for example, should hide the object, but the cloak should still be visible (or vice-versa), or if you push or sit on a couch cushion, it should contract. Lately though, new science has been changing our perception of how materials should behave. For example, recent research into metamaterials; materials that aren’t normally found in nature, has been turning some of what we see as normal, on its head. The development of cloaking devices that hide objects and are themselves invisible, is one example. http://phys.org/news256972609.html Physics Wed, 23 May 2012 06:17:07 EST news256972609
