I suspect, in honesty, my initial interest was based on a private image of streams of unsuspecting eastbound motorists in the American plains states plunging over the edge of a sudden 4,000-mile-high cliff running between Central America and the North Pole, but gradually my attention did turn in a more scholarly manner to the scientific import of the drawing and the realization that the Earth consisted of discrete layers, ending in the center with a glowing sphere of iron and nickel, which was as hot as the surface of the Sun, according to the caption, and I remember thinking with real wonder:"How do they know that?"
坦白讲,我怀疑自己最初对那幅画的兴趣仅源于脑海中的一幅画,里边一群意志坚定的人驾车东去,要穿越横亘在中美与北极之间的一道深四千公里的悬崖。但后来开始慢慢的以一种学术眼光来研究这幅插图背后的科学含义。并意识到地球是由分离的层组成,最里边是由铁和镍构成的发红的球心。图片旁边的说明文字解释说,这个球心的温度同太阳表面一样高。我仍记得当初十分好奇的想知道,他们是如何得知这一切的。
