Brancusi had found his own style. From then on, he began those drastic reductions of natural shapes that left the human head an egglike form on which the features are barely traced, that found in a delicate wafer of blue, mottled marble the poetic essence of fish, that outlined in metal and stone the soaring flight of a bird...
...several years, Bell scientists have been experimenting with thin wafers of crystalline materials known as orthoferrites, which are compounds of iron oxides and such rare-earth minerals as ytterbium, thulium and samarium-terbium. They found that when a strong enough magnetic field is applied, orthoferrites display an extraordinary property: tiny cylinder-shaped areas, or "bubbles," of magnetism are formed in the wafer, their polarity opposite to that of the surrounding material. Often smaller in diameter than a human hair, the magnetic bubbles can be maneuvered and positioned into an almost endless variety of patterns...
Therein lies the secret of their usefulness. Because their presence or absence at specific points in the wafer can be precisely controlled and electronically detected, bubbles can be used to carry coded messages in the on-off binary language of the computer, store reams of data and perform myriad mathematical calculations. Moreover, controlling the position of the bubbles is relatively simple. One method is to send small electric currents through tiny circuits printed on the surface of the crystalline wafer; the currents generate magnetic fields that cause bubbles to form at predetermined locations in the wafer. Currents passed through different...
...upstairs. He found the Protectalarm, pulled out his checkbook, and waited patiently while a new clerk figured out how to work the still camera that photographed every customer paying by check. In her confusion, the clerk wrapped the package without first removing the tags. One of them was a wafer, specially radiated to set off a Knogo sonic alarm in the doorway of the store. John had barely reached the sidewalk when he was surrounded by detectives who accused him of shoplifting...
...EUCHARIST. In recent years, some Catholic thinkers-primarily the Dutch -have questioned their church's difficult doctrine of transubstantiation- that the wafer and wine of the Mass are mystically changed into Christ's true body and blood. They have suggested, instead, a doctrine of "transignification," which argues that the change does not take place in the substance of the bread and wine but in the meaning. Pope Paul reaffirmed the literal interpretation, concluding: "In the reality itself, independently of our mind, the bread and wine have ceased to exist after the consecration, so that they are the adorable...
