For more than five thousand years Chinese doctors have used needles to fight illness. This kind of medicine is called acupuncture. The doctor studies the sick person carefully. Then he puts needles into that person’s body at the right places for his illness. Chinese doctors believe that they can control the body’s natural forces in this way. At first, doctors in the West thought that this was just another kind of magic. Recently, however, they have found out that it is possible to cure many illnesses like this because the needles help the body to produce its own "medicines". In this way the body cures itself.
Nowadays doctors can do a lot of wonderful things. They can use thousands of medicines. They can give you pills and injections. They can even give you mechanical legs or a new heart. Sometimes modern medicine works like magic. But there are still a lot of illnesses that drugs and machines cannot cure completely. Medicine is not only a sc
John Tiernan has spent five years trouble-shooting as an interim manager, hired on short-term assignments by a variety of companies to sort out their problems. He has no desire to return to the certainties of a permanent position, because now, whichever company he is working for, he is perpetually involved in a meaningful task that’s critical to the business at that time.

Thirty-five years after computer scientists at UCLA linked two bulky computers using a 15-foot gray cable, testing a new way for exchanging data over networks, what would ultimately become the Internet remains a work in progress.
University researchers are experimenting with ways to increase its capacity and speed. Programmers are trying to imbue Web pages with intelligence. And work is underway to re-engineer the net- work to reduce spam and security troubles.

Stephen Crocker and Vinton Cerf were among the graduate students who joined UCLA professor Len Kleinrock in an engineering lab on Sept. 2, 1969, as bits of meaningless test data flowed silently between the two computers. By January, three other "nodes" joined the fledgling network.
