[1] Each of us has to be able to think scientifically, and to understand some science. Every day we face decisions that depend on science. Even for decisions that don' t depend on specific scientific facts, science remains the proven set of best methods for acquiring accurate information about the world.

[2] Decisions made by policy - makers in government or business fundamentally affect the well - being of everyone, and most of them know no more about science than does the rest of the general public. Yet they must decide what to do about global warming, expensive space programs, and applications of biotechnology. It' s the nonscientists, not scientists, who have the last word on whether we can drink safe milk. To make such decisions wisely, me decision makers have to be drawn from a scientifically educated public.

[3] As voters, we all bear the final responsibility for those decisions, because we are the ones who decide which candidates will succeed. We need enough sense about science to select the decision makers who will _______________ when faced with scientific questions.

[4] Even if science had nothing to do with the lives of ordinary people, a strong scientific enterprise is extremely important to our society. That requires lots of young people to become excited enough by science that they make a definite decision to become professional scientists. This requires, to some extent, the support and understanding of the general public.

[5] Scientists are not always able to communicate their findings in an easy - to - under- stand manner. Although the scientists should do a better job of explaining their discovery the general public have to expend some energy in making an attempt to understand what they have discovered. Familiarity with the non - official language of science, knowledge of some of the basic principles, and confidence in our ability to fit the new findings into our ever expanding scientific knowledge are valuable qualities of an informed citizen.

Slow down, multitaskers

Think you can walk, drive, take phone calls, e – mail and listen to music at the same time? Well, New York′s new law says you can′t. And you′ll be fined $ 100 if you do it on a New York City street.

The law went into force last month, following the conclusion of a recent research that a shocking number of accidents are relevant to people using electronic gadgets (小玩意儿) when crossing the street.

Who′s to blame? Scientists say that our multitasking abilities are limited. “We are under the impression that our brain can do more than it often can,” says Rene Marois, a neuroscientist in Tennessee. “But a core limitation is the inability to concentrate on two things at once.”

The young are often considered the great multitaskers, but a research suggests this perception is open to question. A group of 18 – to 21 – year – olds and a group of 35 – to 39 – year – olds were given 90 seconds to translate images into numbers, using a simple code. The younger group did 10 percent better than the older group           . But when both groups were interrupted by a phone call or an instant message, the older group matched the younger group in speed and accuracy.

It is difficult to measure the productivity lost by multitaskers. But it is probably a lot. Jonathan Spira, chief analyst at Basex, a business – research firm, estimates the cost of interruptions to the American economy at nearly $ 650 billion a year. The estimate is based on surveys with office workers. The surveys concluded that 28 percent of the worker′s time was spent on interruptions and recovery time before they returned to their main tasks.
