I am a proud Danish citizen.

After my retirement from University of Copenhagen, as a part time science teacher back in the late 2000s at several high schools I used Wikipedia for supplementary material in chemistry, physics, and climate. Mostly I used the Danish Wikipedia, and I soon found out that it was an excellent medium...naturally I had to make a lot of additions and corrections on the way to the classroom. Overall, my contributions reflect my scientific interests and travels.

About the importance of travel and exposure to the world

Some years ago I started the Wikipedia page on SS Arosa Kulm. Now someone must add photos. It is a bit of a personal history: I crossed the Atlantic Ocean with the American Field Service as a 17 year old boy to become an exchange student at Hamburg High School in Western New York. The voyage started from Cuxhafen on August 6, 1956 with stops at Zeebrücke and Southampton. In the middle of the Atlantic we experienced the storm of my life and I think I was the most seasick person on that ship. We arrived to America on August 18, 1956 and docked somewhere in New Jersey. I was seasick walking the streets of New York, on top of Empire State Building, in United Nations Building and meeting with Stephen Galatti. I returned to Europe the following year on Arosa Sky (later known as Bianca C) - a somewhat more pleasant voyage. In the time between my sea voyages I lived with American families; experienced the best of America; had Louis Armstrong sign a consert program; forgot to speak Danish; and met with president Eisenhower and presidents-to-be Kennedy and Johnson. Since then I have travelled the world as a scientist and a teacher.

In 2026 I had to turn off most news from America, but I continue to listen to the very best from America: Nothing but the Blues with Gary Wagner and late shows with Stephen Colbert and Jimmy Kimmel and I also continue to read the New York Times.
