Steven Paul "Steve" Jobs (February 24, 1955 – October 5, 2011) was an American inventor and entrepreneur. He was co-founder, chairman, and chief executive officer of Apple Inc. Jobs also previously served as chief executive of Pixar Animation Studios; he became a member of the board of directors of the Walt Disney Company in 2006, following the acquisition of Pixar by Disney.

In the late 1970s, Jobs—along with Apple co-founder Steve Wozniak, Mike Markkula and others—designed, developed, and marketed one of the first commercially successful lines of personal computers, the Apple II series. In the early 1980s, Jobs was among the first to see the commercial potential of Xerox PARC's mouse-driven graphical user interface, which led to the creation of the Macintosh. After losing a power struggle with the board of directors in 1985, Jobs left Apple and founded NeXT, a computer platform development company specializing in the higher-education and business markets.

In 1986, he acquired the computer graphics division of Lucasfilm Ltd, which was spun off as Pixar Animation Studios. He was credited in Toy Story (1995) as an executive producer. He remained CEO and majority shareholder at 50.1 percent until its acquisition by The Walt Disney Company in 2006, making Jobs Disney's largest individual shareholder at seven percent and a member of Disney's Board of Directors. Apple's 1996 buyout of NeXT brought Jobs back to the company he co-founded, and he served as its interim CEO from 1997, then becoming permanent CEO from 2000, onward. After resigning as CEO in August 2011, Jobs was elected chairman of Apple's board of directors and held that title until his death.

Book

On October 5, 2011, Jobs died in California at age 56, seven years after being diagnosed with pancreatic cancer. On his death he was widely described as a visionary, pioneer and genius—perhaps one of the foremost—in the field of business, innovation, and product design, and a man who had profoundly changed the face of the modern world, revolutionized at least six different industries, and who was an "exemplar for all chief executives". His death was widely mourned and considered a loss to the world by commentators across the globe.

Eye

Eyes are organs that detect light and convert it to electro-chemical impulses in neurons. The simplest photoreceptors in conscious vision connect light to movement. 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.

Evolution eye

Photoreception is phylogenetically very old, with various theories of phylogenesis. The common origin (monophyly) of all animal eyes is now widely accepted as fact. This is based upon the shared anatomical and genetic features of all eyes; that is, all modern eyes, varied as they are, have their origins in a proto-eye believed to have evolved some 540 million years ago. The majority of the advancements in early eyes are believed to have taken only a few million years to develop, since the first predator to gain true imaging would have touched off an "arms race". Prey animals and competing predators alike would be at a distinct disadvantage without such capabilities and would be less likely to survive and reproduce. Hence multiple eye types and subtypes developed in parallel.

Eyes in various animals show adaption to their requirements. For example, birds of prey have much greater visual acuity than humans, and some can see ultraviolet light. The different forms of eye in, for example, vertebrates and mollusks are often cited as examples of parallel evolution, despite their distant common ancestry.

The very earliest "eyes", called eyespots, were simple patches of photoreceptor protein in unicellular animals. In multicellular beings, multicellular eyespots evolved, physically similar to the receptor patches for taste and smell. These eyespots could only sense ambient brightness: they could distinguish light and dark, but not the direction of the light source.

Through gradual change, as the eyespot depressed into a shallow "cup" shape, the ability to slightly discriminate directional brightness was achieved by using the angle at which the light hit certain cells to identify the source. The pit deepened over time, the opening diminished in size, and the number of photoreceptor cells increased, forming an effective pinhole camera that was capable of dimly distinguishing shapes.

The thin overgrowth of transparent cells over the eye's aperture, originally formed to prevent damage to the eyespot, allowed the segregated contents of the eye chamber to specialize into a transparent humour that optimized color filtering, blocked harmful radiation, improved the eye's refractive index, and allowed functionality outside of water. The transparent protective cells eventually split into two layers, with circulatory fluid in between that allowed wider viewing angles and greater imaging resolution, and the thickness of the transparent layer gradually increased, in most species with the transparent crystallin protein.

The gap between tissue layers naturally formed a bioconvex shape, an optimally ideal structure for a normal refractive index. Independently, a transparent layer and a nontransparent layer split forward from the lens: the cornea and iris. Separation of the forward layer again formed a humour, the aqueous humour. This increased refractive power and again eased circulatory problems. Formation of a nontransparent ring allowed more blood vessels, more circulation, and larger eye sizes.

DEEP IMPACT

Deep Impact is a NASA space probe launched on January 12, 2005. It was designed to study the composition of the comet interior of 9P/Tempel, by releasing an impactor into the comet. At 5:52 UTC on July 4, 2005, the impactor successfully collided with the comet's nucleus. The impact excavated debris from the interior of the nucleus, allowing photographs of the impact crater. The photographs showed the comet to be more dusty and less icy than had been expected. The impact generated a large and bright dust cloud, which unexpectedly obscured the view of the impact crater.

Previous space missions to comets, such as Giotto and Stardust, were fly-by missions. These missions were only able to photograph and examine the surfaces of cometary nuclei from a distance. The Deep Impact mission was the first to eject material from a comet's surface, and the mission garnered large publicity from the media, international scientists, and amateur astronomers.

Ants?

It is important we look at the animals small, insignificant, or a waste of time?But keep in mind there is something we look at the animal. Ants are animals that are useful for other creatures, God created all creatures to interlinked .. This time I am talking about ants. After making observations on ant there are a few notes about these animals.- Discipline: The meaning of ants is one that emphasizes togetherness or animal called a colony. Walking with neat is why this animal is referred to as the beast that discipline.- Courtesy: every time I went and met with his fellow ants always faced and never collide with other ants, as they shook hands.- Mutual cooperation: ants including animals decomposing, while the number of ants rely on activities such as foraging and make a comfortable nest for them.- Efficient but not cheap: when certain weather conditions the ants collect as much food as they get, and consume in moderation. As they shared their winter food in their nest, with no scrambling to get food."God created creatures to interact and interrelated."

Stockholm

Stockholm (Swedish pronunciation: [ˈstɔkːˈhɔlm, ˈstɔkːˈɔlm, ˈstɔkːɔlm] is the capital and the largest city of Sweden and constitutes the most populated urban area in Scandinavia. It is the site of the national Swedish government, the Riksdag (parliament), and the official residence of the Swedish monarch as well as the prime minister. Since 1980, the monarch has resided at Drottningholm Palace outside of Stockholm and uses the Royal Palace of Stockholm as his workplace and official residence. As of 2010, the Stockholm metropolitan area is home to approximately 22% of Sweden's population. Stockholm is the most populous city in Sweden, with a population of 851,155 in the municipality (2010), 1.37 million in the urban area (2010), and around 2.1 million in the 6,519 km2 (2,517.00 sq mi) metropolitan area (2010).
Founded no later than circa 1250, possibly as early as 1187, Stockholm has long been one of Sweden's cultural, media, political, and economic centres. Its strategic location on 14 islands on the south-central east coast of Sweden at the mouth of Lake Mälaren, by the Stockholm archipelago, has been historically important. Stockholm has been nominated by GaWC as a global city, with a ranking of Alpha-. In The 2008 Global Cities Index, Stockholm ranked 24th in the world, 10th in Europe, and first in Scandinavia. Stockholm is known for its beauty, its buildings and architecture, its abundant clean and open water, and its many parks. It is sometimes referred to as Venice of the North.

Sail Rock

SAIL ROCK

Sail Rock, or Parus Rock (Russian: скала́ Па́рус, Skala Parus), is a natural sandstone monolith located on the shore of the Black Sea, in Krasnodar Krai, Russia. It resembles the outline of a ship's sail, hence its name.

The monolith lies 17 km to the southeast of Gelendzhik, near the village of Praskoveyevka (which is about 500 meters from the coast) and the farmstead of Dzhankhot (approximately twice that distance from the coast). Sail Rock has a sheer vertical slope confronting the shore of sea, isolated from the mass of basic rock by geological forces. It is more than three-fourths revealed by the tide and lies perpendicular to the coast. What is most remarkable about this landmark is its proportions. While the cliff is only a little more than a meter thick, its height is about 25 meters and its length about 20. Thus, the form of the cliff is described as resembling the outline of a quadrangular sail.

An opening of unclear origin is located in the sail, approximatively 2.5 meters above the ground. Many guides state that the formation was a defense against mountain artillery during the Caucasian War. However, this version of the origin of the opening is under some doubt. In 1903, S. Vasyukov, who was investigating the Black Sea coast, wrote after the inspection of the cliff that it was "[..] shot from a battleship by seamen, they released 4 projectiles, but the wall remained firm, although the traces are noticeable, but they nowhere opened the rock [...]".

benefits of pets

benefits of pets
Pet dog or cat is one way to avoid the symptoms of some diseases, and also enhance children's thinking. Discourse is evidenced by the survey results from some people who keep animals at home and who do not keep animals at home.
The following are some of the discourse:
People who keep animals at home says:
- Young children prefer to play with the pets rather than playing alone, pets are helping with the development of children's memory
- They are more concerned with their neighbors and care about the security environment
- When tired or fatigued after work they are more relaxed when I got home and met with pets
- Melting point of saturation when interacting with the pet, It resulted in reduced
his high blood pressure and cholesterol levels in the body
But keep in mind the cleanliness of animals and the house must be properly addressed.

I was the one person who has a pet at home, and has been proven. I loved the cleanliness of the house, concerned with their surroundings and always healthy living.
