Forty-three years after the birth of ENIAC—the first electronic computer, computers are still in their infancy. We are on the verge of a true revolution when we will see the computer itself“doing science”.In the next decade advances in computer-assisted science should dwarf the past historical accomplishments of scientific computing. Ken Wilson, Cornell University's Nobel laureate, points out that computational science is now the third paradigm of science, supplementing theory and experimentation.

A block may not only indicate the insertion of new information,but also the omission of matter previously shown.The text of the Notice should invariably be read carefully.The limiting lines of a block are determined for convenience of reproduction.They need not be strictly adhered to when cutting out for pasting on the chart,provided that the preceding paragraph is taken into consideration.Owing to distortion the bocks do not always fit the chart exactly.When pasting a block on a chart,therefore,care should be taken that the more important navigational features fit as closely as possible.This is best done by fitting the block while it is dry and making two or three pencil ticks round the edges for use as fitting marks after the paste is applied to the chart.

DISTORTION means that ______.
A.the change in form of the block
B.extract of in form of the block
