简介：系统科学和控制论在二次世界大战以后出现在年里。这些地创造了许多新途径到工程和管理并且贡献了新想法到存在的学术地。新地也越过地的一个范围识别了类似的概念并且开始创造了系统的一个一般理论。另外，系统科学为管理复杂系统创造了许多方法，例如后勤，运筹学和计算机模拟。在1970年代，关于人口和环境平衡有担心。当前与统治正在增加担心，后来，问题的表示的率似乎比我们的机构的能力很好管理他们。这篇论文将讨论系统科学的历史，控制论，提出的问题和答案求婚，困难在在当代的大学和现在在进行之中的研究的一些令人激动的线以内发现一个家遇到了。

简介：我们每晚都要做梦。我们每天晚上要花上两个小时的时间做大约四到六个梦。在梦境中我们经历了各种景象，还有我们现在遇到和过去曾经遇到的人或事。可是我们大多数人都过于重视清醒世界的一点一滴，而没有时间分析我们的梦境，甚至根本就不想去记住这些梦。
