These days, I came cross a professor who is from Germany by reading his book.

So attracted by his book then I checked his personal websit and discovered many of the things I had ever known but not really known till now.

Prof. Frank Werner, is a mathematian in the University of Magdeburg, Germany.

And his info is clearly showed in the website so I am sure people can easily knlw him at a glance.

Then I was so curious about the University in which he works. von djakj hsab University of Magdebury. What is the heck of this difficult name? First I was such disappointed as I really was.

A few mins of stuggling, I determined to break the “stupid door”.

Then I realized that this University is with the name of a famous man who once was the mayor of the Megdeburg, as well as a great physicist.

He is known for his famous experiment of "Megdeburg Hemisphere".

And this Hemisphere was mentioned as one of the most wonderful experiments in the secondary school.

Suddenly I was exicited about encountering an old friend who many years I had not seen.

And also them moment of the happiness liken that "A cat discovered a cat picture on a cup in a grocery store."

I discovered the new world again it seems. I can help to pretend to be unhappy about this experience.

....Afterwards, you guess what?

....Undoubtfully I would probably seek after the footprints of the Mathematicians who are noted as Pineers.
