关于做研究

本文摘录了伊利诺伊大学厄巴纳-香槟分校教授马毅关于如何进行研究的讲座精华。他认为,优秀的研究者应勇于面对自己的恐惧并不断学习,研究是一种热情而非工作,并强调了从设定规则到解决问题的不同研究层次。

Today, I listened a lecture about “How did I learn to do research, or did I?” which was presented by Yi Ma, a professor from University of Illinois at Urbana-Champaign. I extract some important sentences from his presentation as follows:

 

§           When he spoke about how to prepare for doing research, he said:

 

The only way you can improve yourself is to learn things that you are the most afraid of!

 

§           When he spoke about what is research, he said:

 

Research is a game for which you get to set the rules, but it can not be a trivial one!

 

§           When he spoke about how to do research, he said:

                     

Research is not a job, and is more of an addiction.

 

§           When he spoke about four levels of research, he said:

 

Knowing what to do is more important than knowing how.

 

§           When he spoke about what is good research, he said:

 

You recognize a good research result if it keeps you up all night, feeling like your first date.

 

§           When he spoke about what is engineering research, he said:

                                                          

A good engineer needs not to be a good researcher; a good researcher needs not to be a good engineer.

                                           

§           When he spoke about what does doing research feel like, he said:

 

Research is to have faith in you can make the world better!

 

Four levels of research:

 

§           Research assistant

 

§           Homework like research

 

§           Formulate you own problem and solve it

 

§           Formulate problems for others to solve

 

He gave some “avoids” in doing research:

 

§           Think research is only for genius;

 

§           Think yourself is a genius;

 

§           Think you need to know everything about the subject in advance;

 

§           Think you should wait for the most important problem to work on;

 

§           Think a solution is correct just because you can not find anything wrong.
