And that concludes our #schoolweek! What a whirlwind of topics! We had 19 different subjects – I really enjoyed that broad perspective … we probably wanna do this again someday!

Being able to follow our curiosity every day was wonderful. The technique where we repeatedly asked questions, and then go answer them to each other worked extremely well.

We played a school bell sound at the beginning/end of each lesson, here it is for your enjoyment :D https://freesound.org/people/Hansl/sounds/203653/

Thanks for reading! 🏫

And today, on the last day of our #schoolweek, we started with another Astronomy class – more about the Moon's movement, we learned why it seems to "wobble"!

For Engineering, we learned about how combustion engines work, from another lovely Ciechanowski article: https://ciechanow.ski/internal-combustion-engine/ 😍

In Math, we finished the chapter on compression, which covered Huffman codes, and arithmetic codes, where you represent a message with a number between 0 and 1 — super fascinating stuff, look it up!

A joker lesson: City Planning! @piko called in sick, and I flipped through a book. I learned about the "Alsterzentrum", an unrealized building project in Hamburg that was intended to replace St. Georg in the 80s!

In German class, I looked into the history of orthography reforms. Surprisingly (to me), the 1996 reform apparently had a crisis after 8 years, and several newspapers wanted to return to the old orthography rules. In protest, @tazgetroete had an all-lowercase edition! :P

In Politics, we compared different voting systems! We started at @ncase,'s https://ncase.me/ballot/, but quickly veered into proportial voting systems, and the Sainte-Laguë method for distributing seats (which is used for the German Bundestag, and the Hamburger Bürgerschaft). Later, for homework, we wrote a seat-distribution program for a fictitious election.

Math: We continued with information theory, and learned how the entropy of a data source is defined.

Yesterday, we started with an English lesson, where we tried to get an overview of some style guides like the Chicago Manual of Style, the IEEE Style Guide (which is based on it), and the style guides of MDN Web Docs and Wikipedia. I learned that the 2017 edition of Chicago, "e-mail" became "email" and "Internet" became "internet"! :)

Then, Astronomy! We started reading https://ciechanow.ski/moon/, an interactive explanation of the Moon's motion – extremely brilliant!

#schoolweek

Languages: @piko flipped through a new Spanish text book, while I started to build a tiny Japanese dictionary based around Toki Pona's words.

For Biology, we did some… anatomic studies of the muscles in our… forearms :3

And today, we had an after-school club: Linux Club! :D We were pretty tired, but read an overview of how hardware, the kernel, and userspace interact. I didn't know that the CPU can actually stop execution of a program, and transfer control back to the kernel! :O

#schoolweek

In Economics class, we compared different legal structures of firms/corporations in German law, and tried to find out where a "registered cooperative" fits in.

Next up: Crafts! I removed a broken zipper from my backpack, and ordered a new one. Nice to mix in some more manual things! :) And @piko made changes to a pillowcase – now, @piko is no longer afraid of needles; needles are afraid of @piko!

#schoolweek

Wednesday! In History class, we looked into the history of China since 1900, which saw the end of the Chinese Empire, the foundation of the Republic of China (which *still exists* in Taiwan! [disputed]), and today's People's Republic of China.

Physics: More classical mechanics basics. We wrote a little computer simulation for a dampened spring system, and learned that most school physics is just a non-relativistic approximation.
