New version[edit]

I've created a new version at the temporary subpage. --Gray PorpoisePhocoenidae, not Delphinidae 01:57, 20 October 2006 (UTC)

Looks good. Now we wait for it to move into place. -- M (speak/spoken) 01:18, 22 October 2006 (UTC)
I've asked Misza13 to do this task. --Gray PorpoisePhocoenidae, not Delphinidae 14:49, 28 October 2006 (UTC)
Moved. Misza13 15:41, 28 October 2006 (UTC)

Just found something interesting , might be incorporated into the science section, as this could potentially make an invisibility cloak. read it and check it out ( you may have heard of it before.) —Preceding unsigned comment added by (talk) 20:34, 19 March 2008 (UTC)

Shouldn't there be a reference to "Lord of the Rings" in the literature section? Frodo uses a cloak of invisibility there too. —Preceding unsigned comment added by (talk) 20:56, 21 March 2010 (UTC)

Scientific development[edit]

I think this info should be added to the article. John Hyams (talk) 17:29, 25 July 2010 (UTC)


Why is this article not merged with Invisibility? In particular, the scientific contributions (here and for Invisibility) are merely idiosyncratic versions of that in the metamaterial cloaking, varieties of cloaking theories, and other pages. In fact, I suggest all the detailed science from here and Invisibility is moved somewhere else, leaving only a few descriptive sentences and appropriate links. —Preceding unsigned comment added by (talk) 18:00, 9 November 2010 (UTC)

A recurring theme[edit]

In the field of metamterials a new paper often critques a previous work, or method. New papers pertaining to cloaking do this also. This can include an overview of the weaknesses of the previous work. This is probably because the new paper is an advance, or progress in the field. And critiquing the other paper probably helps to illustrate the current work, and maybe ensures funding, and it is appropriate. However, the critiqued work often advances (incrementally) and then critiques the work that critiqued it. Hence, there is no sure bet about which method will actually achieve broad band cloaking in the visible spectrum. Metamaterials and cloaking are in a constant state of flux, will be until a broad band invisibility cloak is produced (in 50 years ???). Hence, I have made some changes in this article.

I copy edited global statements and "forever-always" conclusions. I removed implied, or explicit, singular authorites of this sceince. This is a highly collaborative field, with many participants, and a number of approaches to cloaking. There is no way to predict the outcome - there is no way to know which methods will ultimately succeed. ---- Steve Quinn (talk) 00:34, 28 December 2010 (UTC)

Section copy edit[edit]

I am thinking doing some clean up on the section entitled "Cloaks of invisibility in science". On the other hand, it seems to do well in its current format. ---- Steve Quinn (talk) 06:17, 2 July 2012 (UTC)

Tarnkappe and Alp[edit]

The tarnkappe is probably most often associated with the dwarf Alberich, but association with Alp (folklore) is spurious, and I have removed it. The association is given in the Alp (folklore) citing three vampire handbooks, which have no independent value since the contents are so similar, and only one of the three (Maberry) says the hat worn by the Alp is the tarnkappe. So this is pretty much only citable to only one not so reliable source (fiction writer and not an academic who specializes in German lore). Furthermore, the three vampire references make an assertion that an alp is always found to be wearing a hat (or tarnkappe), which is patently false, since not every alp anecdote features a hat/cape of invisibility. Ergo, the three vampire sources are erroneous and not reliable on this subject. --Kiyoweap (talk) 02:50, 23 July 2014 (UTC)

FWIW, we also have Cap of invisibility.....Cas Liber (talk · contribs) 22:43, 31 July 2014 (UTC)

Article structure is fundamentally wrong[edit]

The lead tells us that "A cloak of invisibility is a fictional theme and a device under some scientific inquiry". Yet the cloak isn't a device under any kind of inquiry at all. More than half of this article is devoted to some as yet unreplicated experiments – we ought to be relying on review papers, not primary research – a great deal of which is uncited and pretty clearly copied from somewhere. What's the relevance of acoustic invisibility anyway? Is this supposed to be an article about the mythological garment or about current research into invisibility in general?

Cloak of invisibility referenced in the Bible[edit]

I wasn't able to locate any reference to the cloak of invisibility referenced in the Bible. I just thought I'd throw that out there. In Acts 12 written around 80-90 AD: 6 The night before Herod was to bring him to trial, Peter was sleeping between two soldiers, bound with two chains, and sentries stood guard at the entrance. 7 Suddenly an angel of the Lord appeared and a light shone in the cell. He struck Peter on the side and woke him up. “Quick, get up!” he said, and the chains fell off Peter’s wrists.

8 Then the angel said to him, “Put on your clothes and sandals.” And Peter did so. “Wrap your cloak around you and follow me,” the angel told him. 9 Peter followed him out of the prison, but he had no idea that what the angel was doing was really happening; he thought he was seeing a vision. 10 They passed the first and second guards and came to the iron gate leading to the city. It opened for them by itself, and they went through it. When they had walked the length of one street, suddenly the angel left him."

It seems clear that wrapping the cloak around him resulted in invisibility with him passing by the guards unaware.
