Personal background
I'm a physicist from Germany born in 1965, interested especially in astronomy and other
natural sciences, science fiction (especially "SPACE above and beyond")
and computer science. I work as software developer and UNIX expert and do also
at home much for my website.


Some less common interests for my background are Pamela Anderson, former
tennis professional Gabriela Sabatini and some more famous (mostly also
beautiful) women; other topics like dinosaurs, birds, environmental and democratic issues are
also of importance to me.

Most important in astronomy were the extrasolar planet discoveries of the recent time, despite no earth like planets could be found yet elsewhere, we have
just begun to make the foundation for later SETI work this way. Necessary
are a true statistic (at the moment it's absolutely inconclusive!) about
them and of course enough earth sized objects, to gain further insights!


Finally I want to thank Compart GmbH (BB, Germany) for letting me not only calculate, but also transmit results with/by the companies machines.

Thoughts about SETI and SETI@home
A computer colleague mentioned once the project and shortly later in autumn
1999, about half an year after project launch, I joined it and run it
immediately with one result per day delivering initially at home solely,
now I use not only that LINUX PC, but also LINUX, Solaris, HP-UX and AIX at work as well as a new Mac with OS X at home
for it. On UNIX SETI@home is a perfect CPU idle time user (nice) process in the background.

It's of great philosophical and practical importance to know about ETIs.
Further it benefits a lot, to build joint efforts in the Internet for addressing
heavy crunching problems like this one. The only drawback of the current SETI@home
is the narrow range of frequencies searched, but I know for now it's impossible
to improve there much --- still too many data!


I'm absolutely convinced of the existence of ETIs, but I can't judge, if we have
a realistic chance to find them and how it could be achieved best. Maybe we
misjudge any piece in the assumptions we make usually? Aimed signals doesn't
make much sense for me at now, we can try this later. Nobody can tell, what
will happen after receiving an ETI signal and even less after a bidirectional
contact is established, but it will be exciting anyway.
