Here is a small selection of my favorite personal links for
1. buying books via
Springer and AMS
2. searching new mathematical literature via LANL
3. getting information about music and, in particular, opera
4. Musik-Vermittlung (homepage of my daughter Stephanie Riemenschneider)
If you are interested, you may
find here a biography of Tilman Riemenschneider (more detailed information is
given in the German edition),
his selfportrait and one of his works . Please also contact the Mainfränkisches Museum in Würzburg. -
My own "creations" in pictorial arts were always rather abstract culminating in sketches like
the divisor with normal crossings à la Mirò.
On the cover photo I am playing a piece
of Johann Sebastian Bach at the "Riemenhaus"
Here is an older one showing me (in 1963, when I was a student in Göttingen) hiking on the peninsula of Athos.
The next photo was taken (in a similar style of almost all participants) at the occasion of the 75th birthday of Professor Kneser in Göttingen
in the Auditorium Maximum of the Mathematisches Institut. It imitades a well known photo of David Hilbert showing him exactly at the same place
when delivering a lecture with one of his printed papers in his hand.
On October 29, 2016, there has been a small ceremony in the same lecture hall in memory of the "Goldenes Doktorjubiläum" of a few persons.
This and the
next photo were shot after the day
of a typhoon at a famous shrine (Dazaifu) south of Fukuoka
in the 1990's
during one of my several visits to Japan with my wife Kyoko.
In 2016 we have been in October on Mt. Rokko, at some waterfalls near Kagoshima and hiking again in the hills near Fukuoka.
Here are some photos from our last stay from October to November 2017.
Near Fukuoka, we visited this time the hometown of the famous Japanese Composer Rentaro Taki, and I performed his piece
Kojo no tsuki (moon over the ruined castle) at his statue on the ruins of Oka castle.
During a conference in Kagoshima we could marvel again at the smoking Mt. Sakurajima and the beginning of
autumnal tints at Lake Rokukannonmiike.
I attach here from time to time just a few of my own favourite photos.
Northern Tuscany: From the villa of Laura and Paolo in Chiatri one has a beautiful view to the summer house of Puccini and to the
Lago di Massaciuccoli. There, in Torre del Lago, Puccini had his main villa, now a museum with a nearby open air theater in which
every year a Puccini opera festival takes place. The lake itself - where Puccini chased waterbirds - is now a wonderful refugium for these
animals. We also visited his birthplace in Lucca, a museum, too, with - among many other items - costumes of Manon Lescault, Turandot and
Cho-cho-san and a piano on which he composed his last opera, Turandot. To be sure, there is also a statue of him in Lucca. Other highlights
of this town are the amfiteatro, the pallazzo Pfanner and its garden, the church of San Michele with a painting of Lippi and the Guignini tower.
North of Lucca, one finds the gothic devils bridge, to the west, there is the - at this time - deserted beach of Camaliore with a view to the marble
near Carrara, and finally, south of Lucca: Pisa with the famous tower and the piazza dei miracoli.
Quedlinburg (Rathaus and a birds view), and the Brocken from Torfhaus.
Goslar: Hotel Brusttuch and Hotel Kaiserswörth and the Kaiserpfalz.
Amsterdam: Rijksmuseum, Concertgebouw and boat trip.
Near Hamburg: A "Rapsfeld" near Haseldorf.
Pond at the Wulfsmühle, flower in the Arboretum.
Hamburg: View over the Elbe from Hirschpark.
A new years view over the harbour from the Plaza of the Elbphilharmonie.
Bremen: The famuous "Roland" standing close to the mayors hall, the "Bremer Stadtmusikanten" and their true order,
a statue on the wall, a window in the dome, a painting of Monet and a modern installation in the Kunsthalle, a sculpture
of Tilman Riemenschneider in the Roselius Haus, and a visit to the Space Center of Airbus Industries
(a model of the I(nternational)S(pace)S(tation)).
Southwestengland: Bath, Cathedral of Wells from outside and inside, Bishops palace, park of Killerton house, Bodmin moor,
cemetary in Tintagel, view to King Arthurs "castle", Padstow, Mt. Saint Michael, storm at Lands End, Stonehenge, Cathedral
of Salisbury and Magna Carta.
Sayonara once more to Japan.
Flowers in the Arboretum near Hamburg.
