作者：艾萨克·阿西莫夫（1920-1992）

俄裔美籍作家，被全世界的读者誉为“神一样的人”；美国政府授予他“国家的资源与自然的奇迹”这个独一无二的称号，以表彰他在“拓展人类想象力”上做出的杰出贡献。

阿西莫夫是一个全知全能的作家，其著作几乎覆盖人类生活的一切方面，上天下海、古往今来、 从恐龙到亚原子到全宇宙无所不包，从通俗小说到罗马帝国史，从科普读物到远东千年历史，从圣经指南，到科学指南，到两性生活指南，每一部著作都朴实、严谨而又充满幽默风趣的格调，为了尽情发挥自己诙谐搞笑的天赋，他甚至还写过一本《笑话集》。

到了晚年，他开始变得“好色”，出版了一系列两性话题的“黄书”。

他提出的“机器人学三定律”是当代机器人研究的基本法则，他预言了今天的生物科技，预言了互联网时代的数字图书馆，预言了人类将进行太空殖民。

终其一生，阿西莫夫最引以为豪的则是：《银河帝国》系列小说。

Now it is not just a case of life or death for Biron, but a question of freedom for the galaxy....
