Cloak of Invisibility Coming Soon
davaguco writes "It seems that we will finally be able to make ourselves invisible" It seems like this story resurfaces every few months and then gets submitted a zillion times so here it is. Personally I'm still waiting for my cloak of evasion. 20% miss chance is awesome.
From the end of TFA: So far the researchers have only worked through the mathematics to prove that the device is plausible. The practicalities of making one have yet to be solved.
SJW: a person who perceives an injustice, and while correcting it, commits a greater injustice.
I can only imagine the power it would take to run a cloak like in Start Trek or Stargate, howerver certain concepts are here. For instance Active Camoflage. Granted it's not refracting light around the object, but it still gets the same result. I don't think we'll see a personal cloaking device, or for that matter one for a ship (where it makes it invisible) for a long time.
That which does not kill me only postpones the inevitable.
I know it, and you know it.
No prototype has been built to demonstrate that it works for any real meaning of "invisible" whether optical, radar or what-have-you.
I'll believe it when I fail to see it.
I assume CmdrTaco is talking about some other game. In D&D, evasion doesn't provide any kind of miss chance. It allows you to take less damage on certain attacks when making a successful reflex saving throw.
Also, there is no cloak of evasion. There is a ring of evasion, though.
If it only blocks one wavelength of light, you just paint the object that colour.
Radio waves (which RADAR uses) are simply light waves. Radar works by bouncing the waves off an object. If this device refracts the light in such a way that it pass around the object without reflecting off of it, then the radio waves would not be able to return a signal to the radar station.

"A professor at the University of Tokyo has developed an optical camouflage system that makes a special reflective material seemingly disappear, including the wearer! The picture on the coat is made by a viewfinder which puts together the moving images behind the wearer. It's hoped the technology will be useful for surgeons to be able to see through their hands and tools and also for pilots so the cockpit floor will be transparent for landings."
Here's a way to do it http://www.h33.dk/usynlig_index.en.html
If I recall correctly, something similar to this was used in the serbo-croatian conflict; one side found that they could detect incoming airborne objects (planes, missiles, etc.) by detecting "holes" in cellphone broadcast beacon radiation. They were basicly able to see every location in the sky where reflection was either greater or less than it should be.
I actually think the trade was cloak for a certain class of Bird of Prey, not warp drive. However, the Vulcans made first contact with Earth, not the Romulans. The Romulans are a sister race to the Vulcans. They both evolved on Vulcan, and then during the Time of Sarek, when Vulcans were coming very close to the point of destroying themselves through constant war, Sarek, the Vulcan "Father of Logic", convinced the majority of the population to learn to suppress their emotions, a (comparatively) small sect decided to leave the planet on several sublight spacecraft rather than supress their emotions. This is referred to by the Vulcans as "The Sundering." In TOS this was initially a closely guarded secret of the Vulcans. These sundered cousins eventually settled on the twin planets Romulus and Remus, and through generations of genetic drift became a separate species. If you look carefully, Romulans have slightly less pointed ears and more prominent brow ridges than their Vulcan cousins. For generations, the Vulcans did not know what had become of their sundered cousins. Sometime after the sundering is when Vulcans developed the warp drive. When the Romulans finally landed, their ships were in very poor shape, and they didn't have much in the way of raw materials or production methods, and were thus sent back to a sort of stone age. When The Federation made first contact with the warlike romulans, neither species had developed warp drive. The first Romulan war was carried out with sublight spacecraft.
Unless that device works directly on your brain (which I doubt), what you say is complete nonsense. The absence of light is perceived as black.
Invisible can merely be concealed in such a manner as to not be detectible to the eye. Transparent allows light to pass through without distortion. Although this sounds more translucent, light passes through with slightly noticible effect.

Speaking from another day and time, you have hit on the whole point of it! Visibility and invisibility are as much psychological as applied physics. I just read what is supposed to be a true account of a maimed Chinese house church leader locked in a maximum security prison who walked slowly through three check points and out the front gate in the light of day. I was myself once a victim of quadranopsia. During the occurance I could not see items in the lower left quadrant of both eyes near the field equator, yet there was a sense of normalcy in my field of vision. There was no perceived abnormalcy until cars passing me in the left lane just vanished! Remember how magicians make things disappear? It is not about the event but one's perception of it. Perhaps the easiest way to make someone invisible is turn him into a geek! For that you don't even need a cloak.
