章節(jié)摘錄

　　Automatic Doors　　When you next step through the doors of a super market'spare a thought forHeron.a talented specialist of ancient“high tech”engineering. Nearly thousand years ago he designed automatically opening doors for the temples of the Egyptiancity of Alexandria.　　Heron had a talent for designing mechanical wonders to surprise people andmake people happy.His design for automatic temple doors was a gift to the Egyptian priests’who for centuries had used wonders’mechanical or otherwise，as a way of strengthening their authority.　　Employing relatively simple mechanical principles，Heron devised a meanswhereby the doors of a small temple would open——as if by unseen hands——when the priest lit a fire on the altar outside the temple.The fire heated the air in a metal globe placed beneath the altar，forcing the water in it through a pipe into an enormous bucket. The bucket was suspended by chains from a system of weights and pulleys，which turned the doors on their pivots as the bucket became heavier.　　A second surprise took place when the altar fire was put out. As a result of the sudden cooling of the air in the globe，the water was sucked the other way through the pipe. When the bucket emptied，it went upward，making the pulley system move in reverse’and the doors closed again.　　Another design include in Heron'S writings could make a trumpet blow when the temple doors opened-a combination of musical doorbell and burglar alarm.　　There need be little doubt that the automatic.door system described by Heron was actually used in Egyptian temples and possibly elsewhere in the Greco. Roman world. Heron himself referred in passing to a similar system used by other engineerg：“Some instead of water use quicksilver（mercury）.”Using mercury instead of water in a machine similar to Heron'S design would certainly have made it more efficient.　　……
