I am Patrick.

very many

Now I am working with Prof. Horst to study Limit Order Books and other related problems. 

Postdoc

If you can jump out from the time-dimension then randomness will not exist and the whole world is determinstic. All substances are crystal and light is the critical state, the main challenge for us comes from dimension restrictions. Thank GOD! We are not omnipotent and future is mysterious, relative randomness exists actually! Probability is meaningful! If tomorrow's stock prices can be known, I would lose my job! Time is unbelievable!
