怎样做科研？ -- 普林斯顿经济学教授的经验之谈
||||
“My System of Work (NOT!)” 是Princeton的经济学教授Avinash Dixit总结的科研经验。虽然是为研究经济学的人写的，但其中的很多观点对做工程的也很有借鉴意义。以下是从这篇文章摘录的：
...of all the lessons I have learnt during a quarter century of research, the one I have found most valuable is always to work as if one were still twenty-three.
As we went along, more than half of the time we found that someone else had been there before. But it was much more fun to do it ourselves.
The breakthrough came when I had by mistake gone to the airport far too early, and had to kill a couple of hours. Once the right idea came, everything worked out really fast.
I do believe that mere relevance of an issue will not guarantee good research unless you have a genuine drive to work on it. ...Good work on an apparently unimportant problem will have more long-run value than mediocre work on one of greater intrinsic importance. And one's judgment of importance can always be wrong; concepts of relevance can change over time.
revolutions are the consequences of attempts to resolve anomalies that are observed in the course of normal science. And the best way to notice anomalies is to do normal research.
Many ideas, and techniques for theorizing, will come to you by accident. But don't wait for such accidents to happen; facilitate them. Always be on the look-out for examples, questions etc that relate to what you are doing, or something you worked on once but set aside.
Learn to manage your time. When asked to contribute to a collective volume, or present a paper at a conference, unless the assigned topic happens to coincide exactly with your interests, follow the Nancy Reagan strategy: "Just say no."
when doing frontier research of real intellectual importance and challenge, do not be afraid to spend a lot of time thinking vaguely, or even "day-dreaming" around the subject.
...four phases in creative work: preparation, incubation, illumination, and verification
Keep a "portfolio" of problems to work on. If you are not making progress on one, switch to another.
Read other people's papers either seriously, or not at all.
If you are doing innovative work, be prepared to meet bias, and be prepared to meet careless dismissal. Give such reports due consideration -- even they may contain useful tips for revision -- but if you have basic confidence in what you are doing, press on. If you meet sheer incomprehension, however, take that as a sign that your writing has failed.
