Klein bottle

无意间看到这个小老头的TED talk Clifford Stool’s talk at TED, 一个有趣的对未知痴迷的scientist,讲起来话来倍精神——活蹦乱跳的。他对science,engineering,technology的定义:

“The first time you do something it’s science, the second time it’s engineering, the third time it’s technology, it’s just being a technician. I’m a scientist: Once I do something, I want do something more.”

但曾是微软CTO的professional jack-of-all-trades的 Nathan Myhrvold却无比好玩,辞职做厨师,BBQ champion,野生动物摄影家,甚至火山研究者(挺羡慕他,不用把生命耗在一件重复的事上):

“Once I do something, I want to do something else.”

我们到底是要专一还是要协调平衡呢? 读一读Steve Pavlina的《Living congruently》,便可明白多维度的学习工作生活还是可以相互协调、相互促进、共同发展的。

话说Clifford的klein bottle,数学领域中的概念就是一种无定向性的one side的平面,没有内外之分,可以到这里围观。跟August Ferdinand Möbius (1790-1868)的莫比乌斯带(Möbius strip)有异曲同工之妙。

usage: the area of architecture has borrowed the idea of Klein bottle, you can refer to http://www.billwang.net/html/2009/17616.html

由此推出,没有无用的创意,只有不爱东脑瓜找应用的懒人。
