The Mulhouse-Thann Tram-train

A few more odds and sods from Triberg. I'm not going to show much more because someone commented on a previous post saying that they will visit Triberg in June, so I'm not going to spoil everything for them, particularly regarding cuckoo clocks.

The Black Forest is well known for its cuckoo clocks, and Triberg is home to the most extreme: the largest, which is a possible stop on the Railway Adventure Trail we covered yesterday, and the smallest, which are housed in the Schwarzwald Museum. But there is also a "first biggest cuckoo clock"... in Schonach. This would be the first clock to be recognised as the biggest by the well-known record book, but it has since been overtaken by the one in Triberg.

It's closed on Mondays, so all I have is this photo from the main road between Triberg and Schonach - in which I've cropped out the clock on the left. The clock is on the old road between the two towns, which is much nicer and at times bucolic. Schonach has a ski jumping hill which I'd like to visit, but didn't manage to fit it in on my one-day trip.

Between the waterfalls and the first biggest cuckoo clock is the Bergsee, a tiny lake with a simple café-restaurant on its edge - decent food, calmer* and not as pricey as downtown Triberg. The lake served as an alternate venue for ice-skating competitions in the 1920s, when Berlin wasn't cold enough!

Japan Weekend coming up!

This weekend, in fact! Every April, Strasbourg hosts some ekiden running races, and a festival of Japanese culture on the side. Taiko drums, shamisen, martial art demos including kyûdô and aikidô, Japan-inspired artists, food... and games like shôgi and mah-jong, the latter of which I will be partaking in as a member of the Strasbourg club. So if perchance you are in Strasbourg this weekend, pop by!

To end the "Canal Contraptions" mini-series, here's a brief look at the Keage Incline on the Lake Biwa canal in Kyoto. Located near Nanzen-ji and its famous aqueducts, it's apparently a popular sakura spot, not that I'd know visiting in July...

Boats were loaded onto wagons at one end of the slope, and hauled by an electric engine up or down before being unloaded back into the water at the other end. Thinking about it just now it sounded rather ludicrous to me, but I was picturing long European-style barges, but the boats of Meiji period Japan were probably not that big, as a picture of the surviving wagon shows.

We didn't go down to the incline, it was just something the friends I was travelling with that day brought up between Nanzen-ji and our next destination. Something to go back for...

Nagahama Castle Ruins

Like Hikone Sawayama, Nagahama Castle is not on the list of Japan's 100 Famous Castles, nor on the list of Japan's Next 100 Famous Castles. Like Hikone Sawayama, it was a pre-Edo period fort which was owned by clans which at some point landed on the wrong side of the unifiers of Japan. Little is left, and short posts mark where buildings would have been. It's a short climb from the base, and the view of Uchiura from this location is pretty good.

This part of Numazu, and the island in the middle of this shot, Awashima, is most famous for being featured in the anime Love Live! Sunshine!!, which I know nothing about but saw some hints of (train for another day). It's possible to see Mount Fuji from here on a good day. And... well, I could see some it...

It's a considerable distance from a train station, though there appears to be a bus stop at the base, but I was driven there by a friend so I don't know how frequent the buses are. We were also lucky to get on a quick boat tour out to Awashima and back, with the chance to see the castle from a the sea, against the hilly backdrop of Izu Peninsula.

Palais Universitaire de Strasbourg

In 1870, a broad coalition of German nations waged a war against France. Napoleon III's Second French Empire fell swiftly, and the Second German Reich formed on the back of this victory, with a Kaiser at its head. Germany annexed Alsace and Moselle, and had particularly grand plans for Strassburg, the capital of the region. While the city centre on the island was repaired after heavy shelling, the Germans decided to develop around it. To the North, the Neustadt, "New Town", was built, with, at its core, a wide avenue with a palatial residence for the Kaiser at one end, and a University Palace at the other, the storefront of a brand new campus complex. It's still part of the university today, with classrooms and all.

Completed in 1884 in a neo-Renaissance style as a monument to Germany's newfound power, the Palace is richly decorated with statues, ranging from effigies of Germania and Argentina - no relation, the Roman settlement at Strasbourg was called Argentoratum -, and historical figures of German science and thought: below, theologist Martin Luther, mathematician Gottfried von Leibniz, astronomer Johannes Kepler and educator Johannes Sturm. Though probably not a direct response, the Eiffel Tower would provide a similar list of French greats a few years later.

France regained Alsace following World War I, and would de-germanify several buildings in the Neustadt area. The home of Germania insurances became the Gallia building, and the effigy of Germania, restored below, was removed from the University Palace. A similar process would be undertaken in 1945, after Alsace was once again be annexed by Germany in 1940 - the University Palace would need de-nazifying.

However, a few symbols remain as a reminder of the Nazi oppression. In the grand hall, called the Aula, a subtle swastika appears among the geometric patterns on the floor. It sits in a corner, as lonesome as it is loathsome. I thought I had a picture of that swastika, but looking through my folders, I don't appear to have taken photos of the interior at all. I seem to remember thinking "nah, it's weird to take pictures of Nazi swastikas". It's still weird, right?

Sangaku Saturday #5

This is it, we've reached our first full sangaku problem! (At least one that I've seen on a real-life tablet.)

We set up the tools in previous posts, so I'll let you work this one out by yourselves: given two circles which are tangent to each other and tangent to a same line, what can you say about the radii of the three smaller, light-coloured circles?

The trains the E10 will replace

Following the announcement of a new Shinkansen type due to enter service on the Tôhoku Shinkansen in 2030, let's have a quick look at the oldest trains on the line, that will be replaced.

The E2 is the oldest high-speed train type that JR East owns, and many examples have already been retired. Built for the slower Jôetsu route to Niigata, they operate the Yamabiko and all-stop Nasuno services.

The E10s will also replace E5 sets. This sounds unreal to me, the E5 is the pinnacle of Shinkansen, still the only train running at 320 km/h in Japan (coupled with the E6, when the couplings work), and still young, having been introduced in 2011! Granted, by 2030, the first E5s will be nearly 20 years old, but they're probably not going to disappear completely in one go.

Photos taken at Utsunomiya station (as far North as I've ever been in Japan).

Everything is ready for Tuesday! How this particular configuration works, as well as the one below, will be covered - we can talk about it on here too afterwards if anyone's interested.

C'est avec grand plaisir que je présenterai le mardi 16 avril à la Maison Universitaire France-Japon de Strasbourg une conférence sur la géométrie pendant la période d'Edo, avec en support le sangaku de Kashihara. Entre grande Histoire et petits calculs. Lien vers les détails 4月16日(火)、ストラスブール市の日仏大学会館に江戸時代の算額についてコンファレンスをします。楽しみにしています！ Looking forward to giving a conference on Edo-period geometry on 16 April at Strasbourg's French-Japanese Institute. Expect a few posts about Kashihara around then. Has it really been 6 years?...

As the maths problems take a break, maybe we can have a brief pub quiz. So...

Q. What's that building on the 10-yen coin?

A. The Phoenix Hall at Byôdô-in, Uji.

Initially built as a villa by a member of the Minamoto clan just before the year 1000, the land was sold not long after to members of a rival clan, the Fujiwaras, who turned it into a Buddhist temple named Byôdô-in in 1052. The most striking feature of the temple is the Amida Hall, which with time gained the name Phoenix Hall due to its overall appearance: the two outer corridors are the wings, and a corridor extending behind is the tail.

At the same time, tea production was picking up in Uji, and by the 14th century, Uji tea had become well renowned. I need to go back there someday, my first visit was just an afternoon flick after completing the climb of Mt Inari in the morning. I thought of going back there in the summer of 2023, but couldn't quite make time for it.

Busy week done! Lots of work especially on Wednesday, and helping Vent d'Est organise their mah-jong tournament on Sunday to cap it off. We were on the boat in the foreground of this photo taken a few years ago - yep, still there today. A more flattering angle for the river, at a greener time of year, below.
