Hello! I am Ludwig Micheler.

As I live in Germany and my English is not good, I usualy try to write and improve articles in the German Wikipedia (my page there),
For a virtual walk around in Marburg
go to the ↑Commons-photo↑
above with description

and to the stairs from bus stop 'Am Plan' up to the castle
(with mouseover jumps upstairs, or to old town).
if you want something to read. Or help to improve or translate articles Petersberg Climate Dialogue and Steering tax in more languages.

Two examples of useful redundancy

(de:COP 19 (2013).

But in the last years, I have contributed a lot of Photos to Commons (for use in WP-articles),

and to the chronological archives there (Media by time), with a structure to view the daily fresh taken and uploaded photos of other photographers worldwide in our sisterproject Commons,

so View

my Commons page with photos and links to some Wikipedia-articles, picture pages like Milky Way, Rosetta mission, the 2016 Summer Olympics, mountains like Grünten and Alpspitze, Le Châtelard (Valais, Switzerland). Contributed to Delhi , mountain Zugspitze and to Contemporary art.

Let's cooperate to bring more knowledge and science in our world ...
