★ Surely You’re Joking, Mr. Feynman!

起的蛮早，和刚到北京时一般早。昨晚半睡半醒，和在火车上摇摇晃晃差不多。不过呢，睡过一个晚上，郁闷缓解了一些，奇妙。解决难题有了头绪了不是，郑重向各位推荐，不过最好你用不到。路上听两位音乐电台主持耍宝，世界又恢复了部分美好，wish myself good luck。

曾有一段每天浏览bloglines里面订阅的blog，大家写的东西很新鲜，但也木有保持下来，看来并非兴趣所在。昨日又重新看了日志，才发觉自己的却好久没有更新了，中断了…还是随便写些琐屑的东西吧，无所谓多严肃，多思考，算是从指尖再读给自己听，奇怪的方式。

想 到便拷贝 my life as a quant里的话给自己些鼓励。从南非赶到哥大攻读理论物理的Derman同志从事数量金融，偶差距甚远，但朴素的人生是我爱读的。和when genius failed不同，伊在自传中对数量金融并无太多着墨，通篇是Derman对人生和智识的诚恳思考。比较羡慕伊先抑后扬的人生，终于，找到自己的领域，最 后回归象牙塔。

扉页：

Amibition is a state of permanent dissatisfaction with the present

心酸的一段

Ten years later,as a postdoctoral researcher at Oxford in 1976,I experienced a minor epiphany about ambition’s degradation.At age 16 or 17,I had wanted to be another Einstein; at 21, I would have been happy to be another Feynman;at 24,a future T.D.Lee would havesufficed.By 1976, sharing an office with other postdoctoral researchers at Oxford,I realized that I had reached the point where I merely envied the postdoc in the office next door because he had been invited to give a seminar in France.

温暖的一段

In the evenings I rode the subway home along Broadway to the Upper West Side and pored over textbooks by Cox and Rubinstein or Jarrow and Rudd,excited to be learning stochastic calculus and using my head again.One evening,someone from my old vanpool to the Labs got into the same subway car as me on Fourteenth Street. Seeing me engrossed in symbols,scribbling proofs on my lap on the shaky train,he laughed good-naturedly but incredulously at me for sitting there and doing mathematics on the subway—that was what you were meant to leave behind when you joined the business world!

But I remember thinking quite the opposite:What an enormous relief it was to be in a place where people actually wanted you to spend
your time on what you liked! I told my vanpool friend that I could easily imagine doing this sort of work for another ten or fifteen years.

觉得Derman其实心思细腻

最后，突然有一个奇怪的想法:这次下决心改下吃饭太快的习惯，吃饭要向张磊敏学习。
