The inhabited history of the Las Vegas Valley stretches to 23,000 b.c. , when much of the area was covered by a prehistoric lake. During this period, the indigenous people lived in caves, hunting the mammals that gathered at the shoreline. The landscape of the valley changed dramatically over the next 200 centuries. The glaciers feeding the lake melted away and the lake evaporated. Fossils tell an obscure story of man's slow and sporadic development. Around 3000 b.c. , native Archaic Indians began to develop a lasting hunting and gathering culture. By this time, the valley was in much the same geographic state as it exists in today, with one exceptionthe presence of artesian springs that bubbled to the surface in several areas. These springs fed a network of streams draining through the Las Vegas Wash to the Colorado River. The areas surrounding the springs were desert oases: sprawling collections of grasses, trees, and wildlife. Many springs lay in areas that would eventually become the center of the modern Las Vegas metropolis. For about 4000 years, the Archaics thrived in a culture that included many signs of early civilization. Signs of even more advancement appeared halfway through the first millennium a.d. , when the Anasazi Indians inhabited the valley. Far more progressive than the Archaics, the Anasazi utilized such formal agricultural techniques as irrigation to assist their harvest. This permitted the Anasazi to achieve a benchmark of advanced societythe ability to live in permanent shelters year-round without need to follow wildlife. Mysteriously, the Anasazi vanished from the valley around a.d.

The factory is highly automated and designed to shift flexibly to produce many different kinds of chips to suit demand. "The diversity is the big difference with this plant," said Richard Doherty, president of Envisioneering, a research firm. "It gives IBM the capability to make so many different kinds of custom chips, and the world is going to custom chips." The 140,000-square-foot plant is a testament to advanced manufacturing technology. The 300-millimeter silicon wafers -- about the size of a standard pizza -- are shuttled around the facility in enclosed plastic pods, which ride on overhead tracks. They drop down from wires automatically into machines, sheathed in stainless steel and glass, for each stage of processing and fabrication. Throughout the 500 processing steps, which typically last 20 days, the wafers are not touched by human hands. The circuits etched into the chips are less than one thousandth the width of a human hair. Human operators are there to monitor the systems, catch errors and fine-tune the production process for maximum efficiency. Because each of the hundreds of processing machines is self-enclosed, and essentially airtight, the uniforms operators wear are less constricting than in the previous generation of chip plants, which looked like space suits. The operators at the East Fishkill factory wear light nylon uniforms, light blue shoe coverings and translucent hair nets made of paper. They look more like workers in a bakery. Yes, said Richard Brilla, director of the new facility, "but the donuts are a lot more costly here." Each wafer, holding hundreds of chips, is worth $6,000 to $10,000 apiece, depending on what insulation, circuitry and materials are used.

The film is set in Igloolik in the Eastern Arctic wilderness at the dawn of the first millennium . http://atanarjuat.com/legend/legend_film.php The wind is blowing over a bleak snowy landscape while a man tries to herd away some marauding dogs . We hear the voice of an old man singing a childish song . Inside a stone house a strange shaman by the name of Tungajuaq , who comes from up north , is singing playfully to the gathered community and camp leader Kumaglak . But among the spectators there are some mistrustful faces . Flash forward to another day . Qulitalik is bidding goodbye to his sister Panikpak , wife of Kumaglak , promising to come if she calls for help in her heart . She gives him her husband's rabbit's foot for spiritual power . Qulitalik tells his sister , '' Tulimaq is the one they 'll go after now . '' It seems that Qulitalik is leaving to escape a threat , and the hope is that one day he will return to help . As Panikpak watches him leave , we hear a voice-over from a woman : '' We never knew what he was or why it happened . Evil came to us like Death . It just happened and we had to live with it . '' Flash back to the original scene in the stone house . The visitor and the camp leader Kumaglak are in a '' friendly '' spiritual duel involving binding in leather thongs . But Panikpak is startled when the stone lamp in front of her breaks in half , and , to the horror of those present , Kumaglak falls over dead . The visitor removes the leader's walrus-tooth necklace from Kumaglak's body , and , passing by Tulimaq , he puts the necklace around the neck of Sauri , the son of the murdered leader Kumaglak , saying , '' Be careful what you wish for '' .

So what is gravity? A typical definition of gravity is that it is a force. It causes an attraction between two masses. According to this definition, anything that has mass exerts a force. Any object exerts gravity on other objects. It does not matter how small it is, it has gravity. The more matter an object has, the more gravity it has. Your pencil has a tiny bit of gravity, but far too little to notice. What about a planet? It would have a lot of gravity. An objects gravity exerts a pull on other objects. Friction only occurs between objects that are touching. Gravity can act between objects that are not touching. In fact, gravity can act over very long distances. Where else can you feel gravity?
