Hi Dr. Ho.
Thank you very much for your comments on my note on the last day of 2009, and your successful prediction 10 years ago.
What you said "If future of science is predictable, then the world will not be so interesting" told me the same idea by Alan Kay: "The best way to predict the future is to invent it." It is really hard to predict how everything goes, indeed hard-working and imagination are all we need.
Thank you again! Happy Chinese Lunar New Year!

这几天靠在床上休息时间看了从你的博客编辑而成的书《科学人生纵横》。知道了你在科技网上写了好几年,现在把你的英文原文和中文翻译过来结集出版。读起来很有意思。我是搞石油工程的,你的专业领域自动化和运筹学方面我不熟悉。但你对中美文化的分析和对人生的感悟,我特别理解和赞同。对比一下中英文翻译也很有收获。虽然英语是我的工作与语言,但我的第一语言还是中文。我猜你看中文没有问题,只是写可能不习惯吧。所以我还是用中文和你交流。如果你看中文不习惯,我也可以用英文。以后我会时常来看你的博客。你特别像我的一位同. 他是 我过去的mentor。他是大陆出生,四十几年前从台湾到了美国读书, Ph.D毕业后已经工作了41年了(同一个公司,同一个妻子,多少年如一,和你一样, 但现在还没有退休,身体特棒,登上比年轻人还走得快)。读你的书对人有所启迪, 就好像与一个老前辈老朋友对话。我喜欢逛书店,就像逛超市一样。看到好书,就喜欢去读,是一种享受。你的这本书是我前天逛书店碰巧找到的。其实应该放在畅销书一类,放科技书类知道的人会太少了。你的书不仅对年轻人有帮助,对我这样的中年人也有所裨益。我希望中国的大学教授和校长都能读一读你的书。

You know what, I have a colleague. Formerly he was my mentor when I joined the company. He and you have a lot in similarity, obtained Ph.D in the U.S., worked more than 40 years in the same company, still married the same wife for many years. However, he is still working in the company, very energetic and healthy. I enjoy reading various good books. I would like that more Chinese readers have chance to read this book. Reading your book is like talking to an old friend, to a knowledgeable scholar, and to a sage. It is not only v ery helpful for the young people, but also beneficial for middle-aged Chinese people like me. I hope that all of the Chinese university presidents can read your book. /an oil man
博主回复:Dear Oilman, Glad you enjoyed the blog book. Helping others was my main purpose in writing my blog. I have made free copies available to several universities. By all means help to publicize the existence of the blog or the book.

Dear Professor HO,I have read your book “Letters from America”. It is very interesting for me to read both your original English and the Chinese translation (both are wonderful!). I am a petroleum engineer, worked more then 10 years before in China as a faculty in a university, and then spent more than 5 years in the U.S. for my Ph.D and worked for about 10 years in American oil industry. Currently I am working in China again for my company for a major capital project. Although I am not familiar with your academic field in automation and operation research, I understand and agree with you completely in your general understanding on life value, Chinese/American culture difference, especially your sharp eyes in Chinese academia. /an oil man

Hi Dr. Ho, I still remember your words on CDC1999--control is going to have a new birth with computational intelligence. right now10 years has passed, how do you think about the development of computational intelligence?

Thank you very much! Happy New Year!
博主回复:It may be subject to debate. But don"t you think a great deal on intelligence have been added to control systems. Just compare two issues of the Transaction of AC and the Control Systems Magazine 10 years apart.
However, in the same article I also said that "the dust heap is full of scientific predictions by well intentioned persons". If future of scienbce is predictable, then the world will not be so interesting.

何老师您好:
学生打扰了,向您请教个问题:我是数学出身的,硕士搞的是矩阵代数;学习控制基础课已经快到一年了,感觉还可以!对控制领域不是很清楚,控制领域哪个方向有发展且与数学(特别是矩阵)联系比较密切,请您指导,学生会向着这个方向努力的!您是控制界的权威人士,若能在您的指点下学习,晓光终身受益!
期待您回复!
学生:韩晓光
博主回复:Take a look at the topic "Linear Matrix Inquality" by Stephen Boyd of Stanford. It may help.

我为一个问题伤透了脑筋,特向各位名牌大学名牌学科的名课名师恭敬地求教……

假如一位院士在他编撰的光学教科书第2页、第4页、第21页、第489页、第540页中多次指出:光的本质是量子的,光的量子理论能够包含光的经典电磁理论。可是,近80年来,“光的量子理论能够包含光的经典电磁理论”却又找不到一个实验证据(见《谁能破解这一神奇的怪现象?》http://www.sciencenet.cn/q/showtopic.aspx?g=physics&id=141)。您将怎样真实地面对学生并给学生讲解?要是那些天赋特好的学生不停地追问实验证据,您将如何应对……

还有,不少名校学风严谨,甚至是《实践是检验真理的唯一标准》的酝酿与诞生地,依贵校的学风校风该如何处理这样的问题……

不希望您马上作答,您可以与贵校的教授们讨论讨论、然后再告诉我……

何老师您好:

我想请教您一下,如果写学术论文要引用一篇文献中的某些实验数据(文献中为图,没有具体数据),可不可以委婉地向文献作者索要实验数据?这样会不会不太好?

请您指教!谢谢!
博主回复:假如你有很好的理由,而且很礼貌的要求,我想一般作者会给你的.

建议数学家带头搞起个[数学圈]!

数学家高斯说: “数学是自然科学的皇后”,笛卡尔也曾说:“数学的概念和证明,能够而且必须应用于一切世俗科学”, 兰 德尔还曾说:“科学产生于用数学解释自然这一信念。”,马克思也说过:“一种科学只有在成功地运用数学时,才算达到了完善的地步!”,实际上任何科学,甚至任何的日常生活,都
离不开数学。
这些都充分说明了“数学”的重要性。
[科学网]有不少数学家,许多博客也都有很精彩的数学博文,和相应的数学评论和讨论。
但是至今还未建立起个[数学圈],不利于有关数学问题的科普和深入的讨论,和促进其创新与发展。
建议数学家带头搞起个[数学圈]!


博主回复:Many thanks for your suggestion, Professor Wu. I am retired and not suitable to be the organizer except as the cheering section member.You should do it.Best regards.

Dear Prof. He,

I"m a PH.D candidate of Harbin Institute of Technology. I have composed one research paper and decide to submit it to IEEE Transactions on Automatic Control. But I"m studying in Japan now, and the university has no IEEE Transactions database such that I can not get enough information about that Transaction. This is the reason I"m writing to you. I wonder that, generally, how much time does this Transaction will cost when reviewing one research paper and the time cost from receiving manuscript to publishing the paper? Thanks a lot. I"m sorry that I don"t know your email address. Therefore, I have to leave a message to you here.

Looking forward to your reply.

Kind regards,

Jian Liu

How to get a paper published - 关于论文发表(原文及译文)
[27]张秀丽   2009-3-17 11:50
何教授,看了您的《新学者融入世界科坛》,很受启发。其中一点是:我一直以为“审稿人”是个很大的荣誉,有很高级别。原来并非,只是贡献自己的服务。我研究机器人,在国外刊物也发表过几篇文章,觉得自己做审稿人也是可以的,立刻给国内的《机器人》杂志发了信,他们回复表示了欢迎。
这是走入学术届的一条路,没有人指点,自己可能意识不到。所以,谢谢您!
博主回复:Often times, young scholars are the most consciencious and up-to-date referees. Best of luck and success to you.

何老师,您好!请教您个问题:美国评选院士是不是有指标限制?就像这次工程院增选院士一样,限定六〇个名额。
博主回复:Yes, every year there is a suggested quota for each discipline determined by the membership committee of the academy. But it is my im pression that this is not an absolutely strict limit that cannot be exceeded in extraordinary cases.

如果一个物理学博士向您请教有关能量不守恒的问题,您会不会把这个博士踢出去?
刘晓东
博主回复:第一我不是物理学博士导師.第二要看他怎么问这问题. 要一个博士研究生退学是一件大事. 不能隨便决定的.

何老师:
My current research is about systems biology and biological networks. I am wondering what"s the strategy to drive a nonlinear dynamic system from one steady state to another one, or from oscillation back to steady state. Could you recommend some books about control theory for nonlinear dynamics system to deal with these kind of problems.

Many thanks,

Zhou Xu

博主回复:I am sorry. This is not my area of expertise. I cannot help you. Nonlinear controllability and biologoical models are fascinating subject to study. You need to consult other experts. Good luck

[22]张清鹏   2008-9-15 21:39
Thank you for your useful instruction.
I have listened your speech at Huazhong Univ of Sci and Tech. As a Control-student, I followed your words "Computational Intelligence will give a new birth to control science. (not exactly the same sentence)" and I chosed to have research experience in Computational Intelligence and Graph Theory to have preparation for further research.

Thank you again for your successful instructions via speeches, talks, the red-book for new researcher, and so forth.
博主回复:You are most welcomed.

更糟糕的是,因为在首都的缘故,我虽然愚笨,但相对于其他地方的朋友,还总是能够找到一些资源,但是这些和应急管理的关系就不是多直接了,但是些方向得到的经费支持却十倍于应急管理。

您说,这样的状况持续下去怎么得了?等99%的理想主义者完全现实起来,我们的科学怎么可能继续发展呢?
[20]陈安   2008-8-15 11:02
何先生可能不知道,近3年来,我一直如“疯子”一般在推进应急管理的理论和方法的研究,自己办了一个完全免费永远免费的电子学术期刊《应急管理汇刊》,并做了一个网站,几乎每天更新,讨论班一般情况下每周两次,因为自己的学生不够,就去其他大学找愿意合作培养来北京跟我学习应急管理的学生(这些基本来源于私人关系),全力的付出也使得我们的研究在学界有了一些影响。但是,您不知道的是,我在应急管理方面拿到的经费在“万元”这个量级上——这可是我准备竭尽全力做的东西啊!也算出了一些个东西(叫做成果),但是居然就没有基金来支持。好在有学界的朋友说:陈安这个团队在应急管理方面做的工作不比那些拥有上亿经费的团队差,这样我也可以聊以自慰了,但是仅能如此而已。
[19]陈安   2008-8-15 11:02
我想我其实是很了解读者趣味所在的,所以,我的博客其实可以让它很热闹,但是热闹之后怕什么都没有,点击量?我的另外一个博客已经有60万了,使得我对点击量这个指标已经非常不敏感了,于是,这个博客其实还是冷清点好。可是,知道把握读者关注点所在的我有时候也难免俗一下,就如昨天突如其来地连写数文来论述海归学者之事。

本来就说今天明天不再写博文,但是何先生的问题我又很想回答,于是在“回复”里写了这些字。今后有机会,还希望和何先生多多学习交流。我也是理想主义情结有点重的人,也不太适合在当前国内的科研大环境里待,但是,没办法了......
