创新与想象

王生

  平艺术贵在创造,科学贵在创新。艺术是情感的表达,追求的是美;科学是理性的事业,追求的是真。二者似乎不搭界,但都离不开人类的想象力,是相互渗透、相互补充的。

  艺术不是科学,但艺术创作却具有科学的品格,所谓增之一分则太长,减之一分则太短,就是这个意思。古人的“两句三年得,一吟双泪流”的深沉慨叹;令人把“你是没有骨气的文人”中的“是”改成“这”,而提议者被尊为“一字、之师”;著名钢琴家因演奏成名的钢琴曲错了一音而后悔。这一切都说明了艺术上的一字之差、半拍之慢,是美感强弱的构成因素、决定成分。尽管艺术采用的是形象的表达方式,但它的表达也有一个基本的技巧适中问题,也要符合客观的规律即科学问题。无科学性,艺术表达就不会有美感,也就难以为人所理解。

  科学不是艺术,但科学发现也常有某种艺术创造的品格,即使有了新的突破、价值和意义,也会是“睫在眼前常不见”,只是有些“美妙”感,至于到底是什么东西,还是不能说清楚、道明白。杨振宁20世纪50年代关于“交换规范场论”的论文就经历了一个由不理解到理解的过程。“在20世纪50年代,我们只觉得这篇文章很美妙。到了20世纪60年代,才觉察到它的重要性。我到1964年以后才清楚认识到它跟数学的关系。”(《杨振宁文集》)电报的发明者美国人莫尔斯原本就是画家,1832年10月他在由法国返回美国的轮船上,一名叫杰克逊的医生在介绍一种叫“电磁铁”的新器件时说:“实验已经证明,不管电线有多长,电流都可以神速地通过。”正是这句话使莫尔斯沉浸在神奇的幻想之中,他大胆设想:既然电流可以在瞬间通过导线,那么我们是否可以用电流来远距离传输信息呢?这个想法使他坐卧不安,从此以后,他告别了艺术,投身到科学领域,专门研究电流传输信息的问题,最终发明了电报。美国发明家郝奥发明缝纫机的针头,德国化学家凯库勒发现“苯环”结构,都是在“无意识”的梦中完成的。钢筋混凝土的发明者既不是著名的建筑师,也不是卓越的力学家,而是一位整天摆弄花草的法国园艺家约瑟夫·莫尼埃。这些事例意味着,科学发现并不只是理性思维的产物,它还依赖于艺术的想象力、创造力,依赖于人们的灵感和顿悟。

  上述的创造和发现说明,艺术与科学、美与真,有重叠、有交融,二者是形象思维与理性思维的统一。王国维曾提到了这一现象,他通过对辛弃疾词《木兰花慢》——“可怜今夕月,向何处、去悠悠?是别有人间,那边才见,光影东头”的研究,认为“词人想象,直悟月轮绕地之理,与科学家密合,可谓神悟”。1964年8月,毛 * * 在同周培源、于光远谈哲学时也认为,“这首诗含有地圆的意思”。西方物理学家海森堡说“美是真理的光辉”,而爱因斯坦直接把科学发现称为“自由创造”,表达的均是同样的意思。为什么会这样?因为审美与科学殊途而同归:同归于历史、实践和生活,分途在求真、抽象与求美、具体的社会分工上。分工的优点是产生了专业和特长,缺欠是出现了职业的痴呆。中外先贤、学者给了我们以忠告。达尔文说,若有来生,不再成为制造公司的机器,每周要读诗、赏画、学音乐。工程院院士许国志诗云:“他生倘得从吾愿,甘为诗书再献身。”由于社会在发展、历史在前进,又由于生活、实践是整体的、不能分割的,产生了专业和特长的强强联盟,消化着消极的弊病,使二者互补成为主流,于是便有了科学与艺术的相得益彰态势。科技关学的诞生标志着这一点,而美育学科的建立,则意味着我国在促进人的自由而全面的发展方面将大有作为。

  艺术与科学的关系启示我们,不论是理论创新、科技创新还是其他创新,都不仅需要科学的逻辑推理,而且需要艺术的想象力和创造力;不仅需要理性,而且需要感性、直觉、顿悟。因此,我们要不断提高理性思维能力,不断提高艺术品味和形象思维能力,这也是人的全面发展的重要内容。

本文第二段和第四段都谈到了艺术的科学性问题,这是重复吗?请说明理由。

        Microwaves may be great at warming up food, but what about warming people?    

        Using microwaves to directly heat owners of a room would save much of the energy wasted by

heating walls and furniture. And despite popular ideas about microwaves, this technique would be safe,

according to Charles R. Burlier of the Microwave Research Center in Marlborough, New Hampshire.

Low-power microwaves only penetrate (贯穿) the skin (low-power microwave penetration in a ham is

about 0.2 inches, for example) and with no negative effects.    

        To test this idea, Buffler subjected himself to microwaves in a special room using a standard

500-watt, 2459 MHz magnetron (磁控管). He found that a person will start to feel warmth at about 20

milliwatts per square centimeter (mw. / sq. cm. ) ; a satisfactory feeling of warmth occurs between 35 and

50mw. / sq. cm. By comparison, a person standing in noonday summer sun feels the amount of 85

mw. / sq. cm. And a frozen meat pie in your microwave oven receives about 1000 mw. / sq. cm.    

        In houses of the future, each room could be provided with its own magnetron, says Buffler. When

you stepped into the living room, for example, a motion detector (运动感应器)would turn on the

magnetron, filling the room with low-power microwaves. In the same way that a microwave oven heats up

a hamburger, but not the plate it’s on, you would feel warmth from the microwaves without changing the

temperature of your coffee table. (You could, however, make your favorite easy chair even more

comfortable by treating it with a radiation-absorbing chemical.)    

        While it might be some time before homeowners are comfortable enough with the idea to set up

whole-body microwave heaters in houses, Buffler says microwaves may attract livestock(家畜) farmers.

Lambs that are born outdoors in winter, for example, are frequently lost to cold. Microwaves could warm

the lambs safely and quickly.

1. Which of the following can tell the main idea of the passage?

A. A new heating system.

B. A new microwave oven.

C. A popular technique.

D. The magnetron.

2. According to Paragraph 2, which of the following does not describe the characteristics of a microwave

heater?

A. It directly heats people in a room.        

B. It heats walls and furniture in a room.

C. It is safe.                            

D. It saves energy.

3. The test conducted by Buffler shows that when a person feels comfortable warmth, he receives about

________________.

A. 20 mw. / sq. cm.

B. 40 mw. / sq. cm.

C. 60 mw. / sq. cm.

D. 85 mw. / sq. cm.

4. According to Paragraph 4, which of the following fills the room with low-power microwaves?

A. The magnetron.

B. The motion detector.

C. The microwave oven.

D. The radiation-absorbing chemical.

5. Which of the following statements about microwave heaters would Buffler most probably agree with?    

A. Microwave heaters will soon be widely used by homeowners.    

B. Microwave heaters sometimes make people feel uncomfortable.    

C. Perhaps microwave heaters will be first used by livestock farmers, who wish to protect their lambs in

winter.
