After Wheeler now Edward Lorenz–father of Chaos theory–died. He coined the term butterfly effect. While studying computer science in Linz I was very impressed by chaos theory and its implications.

Above you can see a strange attractor, the Lorenz attractor, which looks like a butterfly and were introduced by Lorenz in 1963.

Update: Zeilinger schreibt etwas dazu in seinem Blog. Recht viel schlauer macht mich das aber nicht und der Titel verspricht auch viel mehr als er halten kann… :(

Here are the time periods of where and when you can be a part of this astronomical event in Austria:

Sonnenfinsternis Anfang Ende
Wien 11:44 13:54
Eisenstadt 11:43 13:54
St. Pölten 11:43 13:53
Linz 11:43 13:50
Salzburg 11:41 13:48
Innsbruck 11:40 13:45
Bregenz 11:39 13:42
Graz 11:41 13:52
Klagenfurt 11:39 13:50
