I'd love to hear about everything, but mainly the historical context.

I know about that shrine that I mentioned thanks to the astronomer Shibukawa Shunkai, also known as Shibukawa Harumi, whose life was depicted in a movie called Tenichi Meisatsu (天地明察, Insight into the Universe). It starts at this shrine, which has stood at this exact location for 390 years.

Maths (and go) geeks still leave their puzzles at the shrine. I took the ema photo years ago; the other two were taken this week.

Hello! I just saw your post about the conference. I know it's very niche, but I'd love to hear / read more about your sangaku presentation. I actually went back to Konnō Hachiman-gū this afternoon, hoping to see more examples, but no such luck. (I cannot decipher them, of course, but I taught English at a faculty of engineering, and my students could. Sometimes. )

I'll put together something about the shrine, but どうぞお先に。Nudge nudge hint hint.

Hi, thanks for the message!

The presentation was in two main parts: first the historical context of the Edo period and function of sangaku in developing mathematics during that time, and second a closer look at Kashihara Miminashi Yamaguchi-jinja's example with a modern solution. I can't read the sangaku in full, but I have been able to pick out the parts with numbers and compare some of their results with the formulas.

I can probably put together a mini-series at some point. Which parts would you want to hear more about? (That's a general question btw: anyone can reply and add the conversation of course.)

#this one's for the maths fandom #and astronomy lovers #and history boffins

This one’s for amcapril, who asked me what you can do with cherry blossoms (except, of course, look at it). You can also eat it, especially in the form of pickled cherry blossoms. You can already see cherry blossom snacks in convenience stores: this is sakura daifuku (桜大福), a small mochi stuffed with red bean paste and decorated with a salty pickled blossom, sold at 7-Eleven convenience stores.
