Read e-book online Christian Doppler (German Edition) PDF

By Clemens M. Hutter

Der Salzburger Christian Doppler (1803–1853) entdeckte 1842 einen "Effekt", der die Welt veränderte. Es handelt sich um die Stauchung oder Dehnung eines signs bei der Veränderung des Abstands zwischen Sender und Empfänger während der Dauer des indications. Ohne diese bahnbrechende Erkenntnis wären Radar, Ultraschall, GPS, Flugsicherung, Computertomographie, tracking von Operationen und Schwangerschaften oder Satellitennavigation unmöglich! Auch wir erleben den Doppler-Effekt, wenn sich zum Beispiel Feuerwehr, Krankenwagen oder Polizei mit Folgehorn Vorrang im Verkehr bahnen.

Wer aber battle dieser geniale Erfinder? Christian Doppler teilte das Schicksal vieler Größen: Erst kaum beachtet, dann missachtet, endlich – nach seinem Tod – hoch geachtet. Salzburg brauchte lange für die Würdigung seines großen Sohnes. Erst 1900 bekam eine Straße in Lehen Dopplers Namen, und 1903 stifteten inner most eine Gedenktafel an Dopplers Geburtshaus – dann Pause, während in Linz, Prag, Wien und Venedig längst Gedenktafeln Dopplers Wirkungs- und Wohnstätten bezeichneten. Seit 1970 trägt sogar ein Krater auf der Rückseite des Mondes seinen Namen. Salzburgs Nachholbedarf deckte die Wissenschaft: Seit 1987 fördert der "Christian-Doppler-Fonds" Forschung, seit 1995 trägt das gym an der Lehener Brücke und seit 1996 die Heilanstalt in Lehen den Namen Christian Dopplers.
