The idea was two decades ahead of its time, and helped to attach his name to the geostationary orbit above the equator. In 1962, at the chilliest part of the cold war and just after the launch of Sputnik had heralded the space age, he discussed in "Profiles of the Future" the implications of transatlantic satellite radio and television broadcasts, with information raining down on previously isolated parts of the world.

他在20年前就萌发了这个想法，也是这个想法让他把名字贴到了围绕赤道的地球同步轨道上。1962年，也就是爆发冷战最严重的那一年，继Sputnik 人造卫星的成功发送开启了太空世纪后不久，他在《未来的轮廓》一书中探讨了卫星广播和电视广播横渡大西洋的应用，他认为它们将使信息降落到原先与世隔绝的那些地方。

Two years ago, Pfizer bought rights to the medicine, a potent stimulator of the immune system, and inested $10 million in its inentor Coley Pharmaceutical.

Mentions of boron compounds like borax date back millennia. In 1808, within a week and a half of each other, two research efforts, led by the great chemists Sir Humphrey Davy in London and Joseph Louis Gay-Lussac and Louis-Jacques Thénard in Paris, announced that they had isolated boron.

硼的一种化合物硼砂被提及的年代可以追溯到一百万年前。1808年，在间隔一个半星期的时间内，分别由伦敦的Sir Humphrey Davy以及巴黎的Joseph Louis Gay-Lussac和Louis-Jacques Thénard领导的两项研究成果均声称他们分离出了硼单质。

大部分产品开发需要时间，有些是一场革命。10年前，汽车用螺旋齿轮还是利用圆锻件或棒材经过机加工制成，可是今天大体积的齿轮都是经过冷挤压或热锻造制作，轮齿的几何图形一次成型或接近成型。
