The hamadryas baboon is one primate species that fails the mirror test.. The mirror test—sometimes called the mark test, mirror self-recognition (MSR) test, red spot technique, or rouge test—is a behavioral technique developed in 1970 by American psychologist Gordon Gallup Jr. as an attempt to determine whether an animal possesses the ability of visual self-recognition.

Only a few animal species have been shown to have the ability to recognize themselves in a mirror, most of them mammals. Experiments have found that the following animals can pass the mirror test: Humans. Humans tend to fail the mirror test until they are about 18 months old, or what psychoanalysts call the "mirror stage". [104] [105] [106]
The best known research technique in this area is the mirror test devised by Gordon G. Gallup, in which an animal's skin is marked in some way while it is asleep or sedated, and it is then allowed to see its reflection in a mirror; if the animal spontaneously directs grooming behavior towards the mark, that is taken as an indication that it is ...
In fact, a solid with a large Rayleigh number can also convect, given enough time, which is what occurs in the solid mantle due to the very large thermal gradient across it. [ 256 ] [ 257 ] There are small pockets of molten rock in the upper mantle, but these make up a tiny fraction of the mantle's volume. [ 258 ]
Additionally, if one very large space mirror were to be deployed, its massive surface area will be a very large target for space debris. Therefore, maneuvering hundreds of space mirrors or one very large space mirror will prove to be very difficult due to the space debris and the potential size of the space mirror. [30]
It wasn’t just large cargo ships, either; passenger ships made the same route. There’s even a monument at the tip of Cape Horn, in memorial of the more than 10,000 sailors who are believed to ...
The largest optical telescope in the world as of 2009 to use a non-segmented single-mirror as its primary mirror is the 8.2 m (27 ft) Subaru telescope of the National Astronomical Observatory of Japan, located in Mauna Kea Observatory on Hawaii since 1997; [3] [better source needed] however, this is not the largest diameter single mirror in a telescope, the U.S./German/Italian Large Binocular ...
