Warhammer 40,000

Warhammer 40,000 (informally known as Warhammer 40K, WH40K or simply 40K) is a tabletop miniature wargame produced by Games Workshop, set in a dystopian science-fantasy universe. Warhammer 40,000 was created by Rick Priestley in 1987 as the futuristic companion to Warhammer Fantasy Battle, sharing many game mechanics. Expansions for Warhammer 40,000 are released periodically which give rules for urban, planetary siege and large-scale combat. The game is in its seventh edition, which was released on May 24, 2014.

Players can assemble and paint individual, 28-millimetre (1.1 in) scale miniature figures that represent futuristic soldiers, creatures and vehicles of war. These figurines are collected to comprise squads in armies that can be pitted against those of other players. Each player brings a roughly equal complement of units to a tabletop battlefield with handmade or purchased terrain. The players then decide upon a scenario, ranging from simple skirmishes to complex battles involving defended objectives and reinforcements. The models are physically moved around the table and the actual distance between models plays a role in the outcome of combat. Play is turn-based, with various outcomes determined by tables and the roll of dice. Battles may last anywhere from a half-hour to a whole weekend, and battles may be strung together to form campaigns. Many game and hobby stores host games, and official gaming events are held on a regular basis, such as the Throne of Skulls.

USS Sentinel (1918)

The second USS Sentinel, a motorboat built in 1918 by Richardson Boat Co., North Tonawanda, New York, for the United States Coast Guard, was completed on 17 June 1918 and assigned to St. Mary's River patrol, Sault Ste. Marie, Michigan.

Mission completion

Returned to the United States Coast Guard when the services were separated on 28 August 1919, Sentinel served until 1935, being renamed AB-13 in 1923.

Sentinel (FBI)

Sentinel is a software case management system developed by the US FBI with the aim to replace digital and paper processes with purely digital workflows during investigations. There was a previous failed project called Virtual Case File.

The project started in 2006 with a $425 million budget. After several delays, new leadership, a slightly bigger budget, and adoption of agile software development methodology, it was completed under budget and was in use agency-wide on July 1 2012.

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.
