He calculates the Fourier-transform of a rational function in his mind. He inverts a 9 by 9 complex valued matrix on the back of an envelope in ten minutes. At the age of 30, He publishes one chapter of a book and 10 articles every year, in 3 of these articles he is a single author. He works 11 hours a day in his room and he is always busy thinking or calculating. He knows the answer to any physical and mathematical question you ask. He must be a genius.

As a junior researcher with a little experience in writing articles, I have asked a few senior scientists about the part that they think is the best to start writing a manuscript from. Some experimentalists propose to start with the graphs and their captions. For a theory article, some scientists like to start with the the main body of their calculations and then insert the words in between the formulas.

In the presentation guide, repeating questions in order to involve the whole audience is said to be a golden rule for which there is no exception. I have no doubt in the importance of repeating questions, but speakers must be careful not to distress themselves and the audience.

In our department, consisting of 6 groups, we have a weekly colloquium. Once or twice a year, each member gets a chance to present a 45-minute talk for the whole department. During the talk the speaker gets as much comments on her presentation skills as she gets scientific questions. As a result, the presentation-skills of the members of our department improve much faster than the other institute-members who do not practice as much.
