Eye

Eyes are the organs of vision. They detect light and convert it into electro-chemical impulses in neurons. In higher organisms, the eye is a complex optical system which collects light from the surrounding environment, regulates its intensity through a diaphragm, focuses it through an adjustable assembly of lenses to form an image, converts this image into a set of electrical signals, and transmits these signals to the brain through complex neural pathways that connect the eye via the optic nerve to the visual cortex and other areas of the brain. Eyes with resolving power have come in ten fundamentally different forms, and 96% of animal species possess a complex optical system. Image-resolving eyes are present in molluscs, chordates and arthropods.

The simplest "eyes", such as those in microorganisms, do nothing but detect whether the surroundings are light or dark, which is sufficient for the entrainment of circadian rhythms. From more complex eyes, retinal photosensitive ganglion cells send signals along the retinohypothalamic tract to the suprachiasmatic nuclei to effect circadian adjustment and to the pretectal area to control the pupillary light reflex.

Eyes (video game)

Eyes is an arcade game released in 1982 by Rock-Ola.

Gameplay

The player controls a hat-wearing eyeball in a maze. As in Pac-Man the goal is to collect all of the dots to advance to next level, but in Eyes you shoot the dots rather than eat them. Computer-controlled eyes chase and shoot at the player. Shooting a computer eye gives points and removes it from the level, but it will reappear a short time later. Being shot by a computer eye is fatal.

As the game progresses, more computer eyes are added to levels and they take less time to shoot at the player. They also move faster.

Eyes Galaxies

The Eyes Galaxies (NGC 4435-NGC 4438, also known as Arp 120) are a pair of galaxies about 52 million light-years away in the constellation Virgo. This galaxy takes its name from its ring structure which made it popular.

NGC 4435

NGC 4435 is a barred lenticular galaxy with a relatively young (age of 190 million years) stellar population on its central regions that has been discovered by the Spitzer Space Telescope and whose origin may be the interaction with NGC 4438. It also has a long tidal tail possibly caused by the interaction with the mentioned galaxy; however other studies suggest that tail is actually a galactic cirrus in the Milky Way totally unrelated to NGC 4435.

NGC 4438

NGC 4438 is the most curious interacting galaxy in the Virgo Cluster, due to the uncertainty surrounding the energy mechanism that heats the nuclear source; this energy mechanism may be a starburst region, or a black hole powered active galactic nucleus (AGN). Both of the hypotheses are still being investigated.

Flood (They Might Be Giants album)

Flood is the third studio album by Brooklyn-based alternative rock duo They Might Be Giants, released in January 1990. Flood was the duo's first album on the major label Elektra Records. It generated three singles: "Birdhouse in Your Soul", "Istanbul (Not Constantinople)", and the domestic promotional track "Twisting". The album is generally considered to be the band's definitive release, as it is their best-selling and most recognizable album. Despite minimal stylistic and instrumental differences from previous releases, Flood is distinguished by contributions from seasoned producers Clive Langer and Alan Winstanley. John Linnell and John Flansburgh also took advantage of new equipment and recording techniques, including unconventional, home-recorded samples, which were programmed through Casio FZ-1 synthesizers. The album was recorded in New York City at Skyline Studios, which was better equipped than studios the band had worked in previously.

Promotion for Flood included television appearances, promotional videos, and an international tour. The album's mainstream promotion and success contributed to its status as the band's most well known album. Many fans, including young viewers of Tiny Toon Adventures, were first exposed to They Might Be Giants's music through Flood.

Per "Dead" Ohlin

Per Yngve Ohlin (16 January 1969 – 8 April 1991), better known by his stage name Dead, was a Swedish black/death metal vocalist and lyricist best known for his work with Norwegian black metal band Mayhem. He also performed as vocalist of the Swedish death metal band Morbid on their demo December Moon.

Roadrunner Records ranked him No. 48 out of 50 of The Greatest Metal Front-Men of All Time.

Early life

Per Ohlin (sometimes called "Pelle") was born in 1969 in Stockholm, Sweden. As a young child, he suffered from sleep apnea. At the age of ten, he suffered internal bleeding when his spleen ruptured, after what he alleged was an ice skating accident. In the Swedish metal book Blod eld död however ('Blood Fire Death', named after Swedish band Bathory's fourth album Blood Fire Death), his brother said in an exclusive interview that Dead was bullied in school and one day the beatings got out of hand causing the ruptured spleen. He had to be rushed to a hospital, where he was for a time clinically dead.

Format (Common Lisp)

FORMAT is a function in Common Lisp that can produce formatted text using a format string similar to the printf format string. It provides more functionality than printf, allowing the user to output numbers in English, apply certain format specifiers only under certain conditions, iterate over data structures, and output in a tabular format. This functionally originates in MIT's Lisp Machine Lisp, where it was based on Multics ioa_.

Example

An example of a C printf call is the following:

Using Common Lisp, this is equivalent to:

Another example would be to print every element of list delimited with commas, which can be done using the ~{, ~^ and ~} directives:

Note that not only is the list of values iterated over directly by FORMAT, but the commas correctly are printed between items, not after them. A yet more complex example would be printing out a list using customary English phrasing:

Whilst FORMAT is somewhat infamous for its tendency to become opaque and hard to read, it provides a remarkably concise yet powerful syntax for a specialised and common need.
