1939 年纽约世界博览会上，人们在会场底下埋下了一粒时间胶囊，希望 5000 年后也就是 6939 年的人们打开它。
里面放了什么呢？一支钢笔、一套字母积木、记录在微缩胶卷里的新闻事件、一些《生活》杂志、一个丘比娃娃、一个米老鼠茶杯、一美元零钱、一包骆驼牌香烟、一顶 Lilly Daché 帽子、一些植物种子，等等。
除此之外，还有当时最重要人物之一——爱因斯坦写的一封简信，也是我最感兴趣的。他究竟写了什么？
我们的时代充满了创造力，他们的发明可以极大地促进我们的生活。我们正在通过力量穿越海洋，并利用力量来让人类从所有累人的肌肉工作中解脱出来。我们学会了飞行，我们能够通过电波毫无困难地向全世界发送信息和新闻。但是，商品的生产和分配完全是无组织的，每个人都必须生活在被淘汰出经济周期的恐惧中，从而一无所有。此外，生活在不同国家的人们在不规则的时间间隔内互相残杀，因此任何考虑未来的人都必须生活在害怕和恐慌之中。这是因为群众的智力和品格，比少数为社会做出有价值的东西的人的智力和品德低得多。我相信后人会怀着自豪和正当的优越感阅读这些声明。
Our time is rich in inventive minds, the inventions of which could facilitate our lives considerably. We are crossing the seas by power and utilise power also in order to relieve humanity from all tiring muscular work. We have learned to fly and we are able to send messages and news without any difficulty over the entire world through electric waves. However, the production and distribution of commodities is entirely unorganised so that everybody must live in fear of being eliminated from the economic cycle, in this way suffering for the want of everything. Further more, people living in different countries kill each other at irregular time intervals, so that also for this reason any one who thinks about the future must live in fear and terror. This is due to the fact that the intelligence and character of the masses are incomparably lower than the intelligence and character of the few who produce some thing valuable for the community. I trust that posterity will read these statements with a feeling of proud and justified superiority.
