First full day in Dresden! We arrived yesterday afternoon with just enough time to walk around the neighborhood and have dinner at my brother, David’s, house. I haven’t travelled in a while. Not this kind of traveling, at least. So getting here was a bit more challenging than I remember. But it was fine and the train ride was really enjoyable. I’m traveling with my 7 year old son, Marlon and so I’m getting to see everything through his eyes. On the train we walked up and down visiting all the cars. I remember doing this as kid. Marlon loved it! I loved getting to practice my German for the first time and was pleased that people didn’t immediately revert to English.
Today, we spend the day walking around Allstadt - the part of the city with the big old buildings. We saw the Kings residence and the Catholic Church and dundeons! A tour of the dungeon where cannon balls were made was so cool! A really well done walking tour with a ghost for a tour guide and beautiful projections on the walls of the dark dungeon to tell the stories.
The highlight of the day was a math and physics ‘salon’. A museum that housed mathematical instruments from the 16th, 17th and 18th centuries. Old instruments are some of \240my most favorite things so I was in heaven! I looked at everything in there and took a lot of pictures. Taking pictures of things is kind of silly because it’s so easy to access photos these days but I couldn’t help myself. \240Celestial Sphere from the 1600s!! A Herschel telescope!! An astrolabe!! These are things I teach my students about and have never seen. The intricate detail and mathematical precision is impressive. The importance of geometrical and astronomical technologies was high at this time and so these instruments were making big changes in the world. Mostly having to do with navigation but also in a philosophical importance of the owner having a priveged view of the universe and thus proximity to God. What made the biggest impression on me today, in having the opportunity to view these items, was how these were “technologies” just like a cellphone is today. The amount of detaied attentionl and science and trial and error and perfection that was required matches (exceeds most likely) any technology we see today. A big difference is how accessible these were to the general public. We’ve come a long way. Now many more are among the privileged to know the workings of the heavens. As a teacher, I hope to expand that even more.
Used to determine the exact location of the sun as it past the meridian, marking noon.
A celestial sphere that included a clock to keep the location of the sun always lining up. Absolutely stunning marksmanship.
An astrolabe. These things are so cool! Never seen one before!!
