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.

(CNN) -- As Iranian President Mahmoud Ahmadinejad visited the U.N. General Assembly in New York last month, the spotlight was once again on Iran. And true to form, the Iranian president made his fair share of provocative statements for the Western media. But while Ahmadinejad's mercurial rants captured our media's attention, back in Iran a coordinated strategy against the women's movement continued. On the eve of Ahmadinejad's arrival to New York, Shiva Nazar Ahari, a prominent young female defender of human rights, received a heavy sentence of six years in prison on charges including the vague crime of "waging war against God" -- a convenient catch-all offense for anyone who criticizes the regime and its human rights record. There's no denying it -- Iran's women have had a bad year. Nazar Ahari joins a steadily increasing number of other women's rights activists who are in prison for no greater crime than their attempt to fight for the rights of the women. Hengameh Shahidi, Alieh Eghdam Doust, Bahareh Hedayat and Mahdiyeh Golrou have all been sent to Tehran's notorious Evin Prison on trumped-up charges related to their activism. And while Nobel Peace Prize laureate Shirin Ebadi, arguably the most internationally recognized Iranian women's rights activist, remains unable to safely return to her country, the government is targeting those affiliated with her for arrest and imprisonment, including her lawyer Nasrin Sotoudeh and her former aide Jinous Sobhani. Since the 2009 disputed elections and associated government crackdown on the overall reform movement, the government has increasingly targeted women activists. The reasons behind this go well beyond the misogynist nature of Iran's religious leadership. Rather, it is more part of a deliberate and calculated strategy of the Iranian authorities to strike at the heart of the regime's greatest vulnerability -- internal legitimacy with its own people. See more CNN.com opinion articles Iran's government recognizes and fears the broader power of the women activists who have been on the front line of reform in Iran for more than a decade. One can roughly draw an analogy between the women's movement in Iran to movements of religious groups in Burma or Tibet, or the labor "solidarity" movements in the former Eastern bloc and associated labor-Roman Catholic solidarity in Poland -- all advocating initially for the freedoms of a specific group but which provoked government fears for their transformative power to promote broader human rights progress. While the outside world occasionally reacts to the most egregious manifestations of Iran's repression of women -- such as the international condemnation associated with Sakineh Mohammadi Ashtiani, an Iranian widow sentenced to stoning on charges of alleged adultery -- these events are often portrayed simply as a consequence of the regime's archaic viewpoint about gender.

Mechanical energy is a combination of the energy of motion or position. This type of energy describes objects that are moving or could move. A moving ball can have energy from motion. An arrow can also have the energy of motion. Both are types of mechanical energy. Can you think of some other examples? Where does the energy of motion come from? It comes from the energy created by position. This energy is stored energy. This means it is not moving yet, but it has the potential to move. How can you store energy? The arrow gains energy from the drawn bow. As the arrow is released, the bow releases its stored energy and puts the arrow into motion. Can you think of some other ways to store energy using position?

Brad, Texas (CNN) -- Authorities were working on plans Friday for residents who were forced to flee a wildfire in northern Texas to return home, a day after firefighters made progress battling the blaze that destroyed dozens of homes. The blaze in Palo Pinto County scorched 6,200 acres by Thursday, according to the Texas Forest Service. The fire is burning near the resort of Possum Kingdom Lake, near the town of Brad, about 100 miles west of Dallas. "We feel much better about this fire today," as the blaze is now 50% contained, said John Nichols, a spokesman for the Forest Service. He said evacuations were lifted for some residents forced to evacuate the fire, which was driven by high temperatures and dry winds. The wildfire has destroyed 40 homes and nine RVs since it began Tuesday, the Forest Service said Thursday. Firefighters were receiving support from aerial tankers and helicopters. Authorities are mapping out plans to allow residents to return to their homes, said Palo Pinto County Sheriff Ira Mercer. Authorities also are trying to open the lake for the Labor Day holiday, he said. On Wednesday, evacuations were ordered in several communities on the north side of the lake after the fire charged over a ridge and approached a dam on the lake, CNN affiliate WFAA reported. The wildfire was moving so fast that the Forest Service pulled out of its command observation post, telling journalists and onlookers to get out of the way of the fire. "My house is right through here, though it may be gone," Tom Hardeston told WFAA as he watched the fire. Nearby ranchers battled to save their herds from the encroaching fire. "I'm just moving them from pasture to pasture," Cindi McCoy told WFAA, referring to her livestock. "As one pasture burns, I'm moving them back to that one and bring(ing) them back around."
