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.

Mayo (Dáil Éireann constituency)

Mayo is a parliamentary constituency represented in Dáil Éireann, the lower house of the Irish parliament or Oireachtas. The constituency elects 4 deputies (Teachtaí Dála, commonly known as TDs). The method of election is the single transferable vote form of proportional representation (PR-STV).

History and boundaries

The constituency was created by combining the former constituencies of Mayo East and Mayo West, and used for the first time at the 1997 general election. It spans the entire area of County Mayo. This area includes Castlebar, Westport and Ballina. Mayo is the largest Dáil constituency in Ireland by area.

At the 2011 general election, this was the constituency of Fine Gael leader Enda Kenny, who subsequently became Taoiseach. Fine Gael won four out of five seats in Mayo at that election. This was the first time in the modern era that any party won four seats in a Dáil Éireann constituency; the last such time was in the era of six- and seven-seat constituencies. It was the first time that any party won four seats in any five-seat Dáíl Éireann constituency. At the 2002 general election Fine Gael suffered its worst electoral performance ever, losing 23 seats nationally, a figure larger than expected and with its overall vote down 5%. Kenny himself came close to losing his seat and even went so far as to prepare a concession speech. In the end he won the third seat in the five-seat constituency.

Mayo (UK Parliament constituency)

Mayo was a parliamentary constituency in Ireland, which returned two Members of Parliament (MPs) to the House of Commons of the Parliament of the United Kingdom from 1801 to 1885.

History

The constituency was created at the Act of Union 1800, replacing the earlier Mayo constituency in the pre-union Parliament of Ireland. Under the Redistribution of Seats Act 1885 it was divided into four new single-seat constituencies: see East Mayo, North Mayo, South Mayo and West Mayo.

Boundaries

This constituency comprised the whole of County Mayo.
