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.

Animal multilayer reflectors work in the same way as a man-made dielectric mirror (or Bragg mirror) being composed of alternating layers of high and low refractive index, the thickness of each layer being 1/4 the wavelength most strongly reflected. [8] To reflect a wide range of wavelengths, the spacing must vary through the thickness of the ...
The amount of water needed varies by person, weight, diet, activity level, clothing, and the ambient heat and humidity. Water does not actually need to be drunk in pure form, and can be derived from liquids such as juices, tea, milk, soups, etc., and from foods including fruits and vegetables. [346] [347]

The song was released in 1994 as the third single from the album Bat Out of Hell II: Back into Hell and it reached number 38 on US's Billboard Hot 100 , and number 26 in the UK Top 40 .
The mirrors deflect x-rays at very shallow angles, like skipping pebbles across a pond; in order to make an image, each x-ray is reflected twice – once from each member of a pair of cylinders. Four pairs of cylinders are nested inside one another to increase the size of the telescope, in order to collect more x-rays.
