Ex Input:
IBM opened a sprawling and sophisticated semiconductor factory here on Wednesday that cost more than $2.5 billion to build and equip, the largest single capital investment the company has ever made. The factory, which opens as the computer chip business is in a slump, is a costly and risky move for IBM. But it is also an expression of confidence by the company that it can remain a technology leader in the highly competitive global semiconductor industry, and a commitment that the best place to execute that strategy is in upstate New York. IBM is an exception among computer makers in that it still invests heavily in research to advance the design, manufacture and materials used in semiconductor chips. It is spending more than $500 million a year on semiconductor research and development. The factory will produce a wide range of specialized semiconductors used in everything from the largest mainframe computers to cell phones and video-game consoles. The new plant is part of IBM's push to gain a strong lead in chip-making beyond the personal computer business, where Intel and East Asian chip producers hold the advantage. "The core of our strategy is to lead in technology and attack the high-performance segments of the market," said John Kelly, senior vice president in charge of IBM's technology group. An advantage to having the semiconductor fabricating factory here, Kelly explained, was that it was very close to its research laboratories in nearby Westchester County, N.Y. To stay ahead in advanced chip technology, he said, moving innovations out of the labs and into the factory as fast as possible is crucial. "What we call the lab-to-fab time should be as close to zero as possible," Kelly said. "If our strategy were anything but to be on the leading edge, we'd have put the plant in Asia." The new factory, which will begin normal production early next year, will employ about 1,000 people. <sep>What does IBM's senior vice president in charge of their technology group, John Kelly, feel that the location of the new plant is so important?<sep>To increase the lab-to-fab time

Alexander earned the epithet "The Great" due to his unparalleled success as a military commander. He never lost a battle, despite typically being outnumbered. This was due to use of terrain, phalanx and cavalry tactics, bold strategy, and the fierce loyalty of his troops. The Macedonian phalanx, armed with the sarissa, a spear 6 metres (20 ft) long, had been developed and perfected by Philip II through rigorous training, and Alexander used its speed and maneuverability to great effect against larger but more disparate Persian forces. Alexander also recognized the potential for disunity among his diverse army, which employed various languages and weapons. He overcame this by being personally involved in battle, in the manner of a Macedonian king. In his first battle in Asia, at Granicus, Alexander used only a small part of his forces, perhaps 13,000 infantry with 5,000 cavalry, against a much larger Persian force of 40,000. Alexander placed the phalanx at the center and cavalry and archers on the wings, so that his line matched the length of the Persian cavalry line, about 3 km (1.86 mi). By contrast, the Persian infantry was stationed behind its cavalry. This ensured that Alexander would not be outflanked, while his phalanx, armed with long pikes, had a considerable advantage over the Persian's scimitars and javelins. Macedonian losses were negligible compared to those of the Persians. At Issus in 333 BC, his first confrontation with Darius, he used the same deployment, and again the central phalanx pushed through. Alexander personally led the charge in the center, routing the opposing army. At the decisive encounter with Darius at Gaugamela, Darius equipped his chariots with scythes on the wheels to break up the phalanx and equipped his cavalry with pikes. Alexander arranged a double phalanx, with the center advancing at an angle, parting when the chariots bore down and then reforming. The advance was successful and broke Darius' center, causing the latter to flee once again. When faced with opponents who used unfamiliar fighting techniques, such as in Central Asia and India, Alexander adapted his forces to his opponents' style. Thus, in Bactria and Sogdiana, Alexander successfully used his javelin throwers and archers to prevent outflanking movements, while massing his cavalry at the center. <sep>How did Alexander use the phalanx in the battle of Granicus?<sep>Armed with the sarissa
