Martin Nowak is MathDoc and PianoDoc
On February 18, 2005, Dr. Martin Nowak from Germany, found the new largest known prime number, 225,964,951-1. The prime number has 7,816,230 digits! It took more than 50 days of calculations on Dr. Nowak’s 2.4 GHz Pentium 4 computer.
See also www.Mersenne.org but his largest prime number has been overrun in the meantime for several times…..
By the way, Martin plays the piano very well and he has participated in two piano master classes with Wolfgang Ellenberger.
The latter has given a piano recital in his house arranged by the round table 101 (?) in the ninties.
