Disappearing - July 2011


Disappearing - Economy


Nothing is disappearing faster than balance in the global economy
so please stay on top of evolving stories. Next week will be big.
Your life as you know it could disappear.




Disappearing - Reality


This week I seem drawn to stories about things that disappear. Many of you may be experiencing the rapidly accelerating closure ... faster and faster until it disappears. People are noticing the illusion of reality while looking at objects in their daily lives. Let's call this the Inception Effect when everything collapses at the end of the film and the creators of the illusion wake up.

It's all projected illusion - nothing is real except the players who created it.




Disappearing - Harry Potter

In the beginning, magician Harry Potter had an invisibility cloak that could make him disappear. The last Harry Potter film Harry Potter and the Deathly Hallows – Part 2 premiers this week. IT ALL ENDS. FADE TO BLACK


Abracadabra - It All Disappears

Abracadabra is an incantation used as a magic word in stage magic tricks, and historically was believed to have healing powers when inscribed on an amulet. The word is thought to have its origin in the Aramaic language, in which abra means "to create" and cadabra which means "as I say", providing a translation of abracadabra as "create as I say", thus its use in magic.

In popular culture, the expression "avada kedavra" is used as lethal spell known as the Killing Curse in the "Harry Potter" novel series. During an audience interview at the Edinburgh Book Festival on 15 April 2004, series author J. K. Rowling had this to say about the fictional Killing Curse's etymology: "Does anyone know where avada kedavra came from? It is an ancient spell in Aramaic, and it is the original of abracadabra, which means 'let the thing be destroyed.' Originally, it was used to cure illness and the 'thing' was the illness, but I decided to make it the 'thing' as in the person standing in front of me. I take a lot of liberties with things like that. I twist them round and make them mine."




Disappearing - Cloaking Space-Time


Invisibility gets a reality check   MSNBC - July 15, 2011
Harry Potter's invisibility cloak comes in handy for the final installment of the boy wizard's film saga, but real-life invisibility technologies might well be at least as useful - even if they aren't as cool as Harry's cloak. For the foreseeable future, the benefits provided by the real-life gizmos that have come to be called "invisibility cloaks" or "cloaking devices" really won't have much to do with the kind of tricks you'll see in "Harry Potter and the Deathly Hallows: Part 2." Sorry to disappoint, but you won't be able to throw a high-tech fabric over your head and disappear from the scene when the bad guys come looking for you.


Cloaking devices are advanced stealth technologies still in development that will cause objects, such as spaceships or individuals, to be partially or wholly invisible to parts of the electromagnetic (EM) spectrum. Fictional cloaking devices have been used as plot devices in various media for many years, but developments in scientific research show that real-world cloaking devices can obscure objects from at least one wavelength of EM emissions. Scientists already use artificial materials called metamaterials to bend light around an object.


Monday I blogged about disappearing ships.

Today we talk about a way to make events disappear ... check this out.


Space-Time Cloak Possible, Could Make Events Disappear?
 
National Geographic - July 12, 2011

Material would adjust speed of light to hide actions, physicists say. Fiber optic cables (pictured) could help prove the theories behind the new "space time" cloak concept. It's no illusion: Science has found a way to make not just objects but entire events disappear, experts say. According to new research by British physicists, it's theoretically possible to create a material that can hide an entire bank heist from human eyes and surveillance cameras. "The concepts are basically quite simple," said Paul Kinsler, a physicist at Imperial College London, who created the idea with colleagues Martin McCall and Alberto Favaro.

Unlike invisibility cloaks - some of which have been made to work at very small scales - the event cloak would do more than bend light around an object. Acoustic 'Invisibility' Cloaks Possible

Instead this cloak would use special materials filled with metallic arrays designed to adjust the speed of light passing through. In theory, the cloak would slow down light coming into the robbery scene while the safecracker is at work. When the robbery is complete, the process would be reversed, with the slowed light now racing to catch back up. If the "before" and "after" visions are seamlessly stitched together, there should be no visible trace that anything untoward has happened. One second there's a closed safe, and the next second the safe has been emptied.

Our view of the world is determined by what our eyes see, our ears hear and our noses smell, or what the philosopher Bertrand Russell termed "sense data". But we know from simple optical illusions that our eyes can be fooled – things are not necessarily always what they seem. However, the techniques that physicists have recently developed to manipulate the path taken by light and other electromagnetic radiation are not mere tricks of the eye: they are real advances that can result in some fascinating and useful effects.
