61 years
I was born on Wednesday, November 1, 1961 at 9:45 in the morning (CET). That
means that today, I will be 61 years according to the calendar and 22280 days
old. But how old am I really? The tropical year, the time that it takes for the seasons to return, is said
to be 365 days, 5 hours, 48 minutes, and 45.19 seconds. Today, around 4:19
in the night, it was 61 tropical years since I was born.
But the tropical year is shorter than the sidereal year, the time taken by the Earth to orbit the Sun once with
respect to the fixed stars, namely 365 days, 6 hours, 9 minutes, and 9.76
seconds. That means that, tomorrow at 1:03:55 it will be 61 sidereal years
after I was born. The average anomalistic year, the time taken for the Earth to
complete one revolution with respect to its apsides, is 365 days, 6 hours, 13 minutes, and 52.6 seconds. That means
that, tomorrow around 5:51:28 it will be 61 average anomalistic years since I
was born.

Pier Paolo
Pasolini's Saló o le 120 giornate di Sodoma (1975) by photographer and visual
artist Rein Jelle
Terpstra, which has editted frames from the film that show the many
prominent futuristic paintings on the walls.
At 14:33, I bought the book 100 Artists' Manifestos:
From the Futurists to the Stuckists edited by Alex Danchev, written in
English and published by Penguin Adult in 2011, ISBN:9780141191799, from the museum shop for € 19.95.
Book

geschiedenis van de mensheid in 515 kaarten written by Christian Grataloup,
translated by Henriette Gorthuis from French into Dutch, published by Nieuw
Amsterdam in 2020, ISBN:9789046827321, from bookshop Broekhuis
for € 19.95.
Dutch water line
This afternoon, Conny and I visited the Waterliniemuseum, which a museum is about the Dutch water lines, which
by means of indundation were used by defend against attacks by foreign
countries. The museum is inside the fort near Vechten. This fort is one of
about fifthy that are part of the New Dutch Water Line, which was meant to
defend the provinces North Holland, South-Holland, and the west part of Utrecht including the city Utrecht. The old water line did not include Utrecht.
Next, we visited Castellum
Fectio, which is just west of the fort. It is part of the Limus Germanicus, the northern border of the Roman Empire and the
unsubdued Germanic tribes. The next castellum (fort) to the west, is Traiectum, which is located in the center of Utrecht. The book
Limes atlas has some interesting maps explaining the position of limes and
the various Roman forts in the Netherlands.
We went to Utrecht were we are going to stay for two nights. On the way to a
Greek restaurant, we visited the bookshop Steven Sterk. At 17:55, I bought the
book Actie-Reactie: 100 jaar kinetische kunst written by Serge Lemoine,
Marianne Le Pommeré, and Emily Ansenk, edited by Charlotte van Lingen,
written in Dutch and published by Lannoo in 2018,
ISBN:9789401456234, for € 12.50.
After having our dinner at the Greek restaurant in one of the wharfs at Oudegracht, we walked through the city center, looking at some of the
light art works that are part of Utrecht Lumen. We visited:
- Bridges
- Ganzenmarkt tunnel
- Sint Willibrord Church
- Jams Light
- Drift Vaults
- Marking the Castellum Wall (off)
- Lights of Saint Peter's Church

DOMunder
This morning, Conny and I, walked through some of the
many alleys in Utrecht. We walked through the following (where the numbers in
square brackets refer to the numbering used in Stegenboek, rapport en kaart):
- Ridderhofstad [228]
- Catherijnesteeg [239]
- Catharinatuinen [210A]
- Abraham Dolehof [211]
- Abraham Dolesteeg [210]
- Brandstraat [146]
- Zwaansteeg [140]
- Jacobsgasthuissteeg [139]
- Walsteeg [116]
- Schildershof [115A]
- Driehoek (to Mariahoek) [114]
- Mariagang [113]
Around noon we arrived at the Domplein (Dom Square), which is where the nave of
the St. Martin's Cathedral (usually refered to a the Domkerk) used to be,
which on 1 August 1674 was destroyed by a summer storm, maybe including a bow echo (see: A reconstruction of 1 August 1674 thunderstorms over the Low Countries).
The nave of the church was never rebuild. We did the DOMunder tour. After some introduction, we descended under the Domplein to
view the excavations. These excavations proved the presence of the Traiectum and established it location to included the current square. It
was interesting to hear the 2000 long history of the square.
At the end of the afternoon, the evening we visited bookshop Broese at the new location that they moved to. I was a bit
disappointed. The shop felt very crowded and the amount of ramsj (sale of new,
hard-to-sell books at reduced prices) has been reduced greatly and placed in a
'corner' of the shop. The exact science section of the bookshop had no books
on math and physics, but did have a lot of management related books.
We had dinner at Silk Road, where we had
dishes from Route 1: naan, zeitun, hummus, muhammara, murgh massale, kofte,
tabouleh, bahar, and Route 2: naan lahasun, baba ganoush, hummus mazara, dahl,
tajine, dopiazza gosala, salat mazara, kaeng kari kai, plov. We also had some
desert. Although the dishes did not look large, it was still enough and
definitely a very nice experience with a lot of interesting tasts.
We also walked through some alleys, the first two on the way to the restaurant.
These are:
- Lauwersteeg [81]
- Jodenrijtje [79, 80]
- Massegast [87]
- Hekelsteeg [86]
- Hamsteeg [78]
- Drieharingstraat [75]
- Zakkendragerssteeg [74]
- Achter Clarenbrug [109]
- Wijdepoort (closed) [98]
- 1e Buurkerksteeg [99]
- 2e Buurkerksteeg [99]
- Buurkerkhof [97]
- 3e Buurkerksteeg [100]
- Donkerstraat [100]
- Kuipersteeg [104]
- Boterstraat [123]
- Lijnmarkt aan de werf [126, 127, 128]
We also saw the light art work of Utrecht Lumen at Buurkerkhof.
De Meer 1
Conny and I visted Castellum Hoge Woerd were we saw the exhibition about De Meern 1, a 25 meter long Roman ship that sank due to an accident based
on the fact that many tools and personal items were found in the area the cabin
was located. A unique find and quite interesting. We also saw the exhibition Natuur in Eenvoud with sumi e painting by Martha
Goedings and raku
creamics by Anke van der Kwaak.
We also visited the museum with many archaeological finds, but we did not find
any information about the roman castellum, if it was indeed located at the
location of the Castellum Hoge Woerd, which has the form and size of the
castellums found in the Netherlands.
15.3° Celsius
The temperature at Twenthe Airport has gone up to
15.3° Celsius, which breaks the previous record of 14.9° on this date
in 2015. This is the tenth warmest day record of this year. Below a picture
that I took this morning of a Garden marigold (Calendula officinalis) flower, which I sowed on Sunday, April 10, 2022. The normal flowering periode is from may to
november.
Book
At 16:06:24, I bought the book Limes atlas edited by Bernard Colenbrander, written in Dutch and published by 010 Publishers in
2005, ISBN:9789064505355, second-hand from Polynea (webshop) for € 75.00.
(The book will be send to me through a package delivery service.)
Infinite
In the past weeks, I have been working on trying to prove that it is indeed
possible to create infinite irregular grids of
squares and equilateral triangles. I wrote a program for manipulating vertex labeled graphs. The program constructs
two vertex labeled graphs, calculates the product of these graphs, prunes any
dead-ends, and checks that all edges in the original graphs is still
represented in the product graph. If that is the case, it means that there is
a matching between the two graphs (on the labels) such that for any infinite
walk in one them, there is also a path in the other graph. Because the two
labeled graphs are related to the edges of all possible sequences of triangles
and squares, it proves that above and under any sequence.
Patches of snow
This morning, when I biked to my office, I saw some patches of snow. I saw some layers of snow on some car roofs and from this I conclude
that about 0.5 to 1cm of snow fell during the night. Only at the end of the
night (after 5 o'clock) the temperature dropped below zero, reaching a
temperature of -1.4° Celsius at Twenthe Airport. The night before the
temperature dropped to -8.2° Celsius, which is not a record, but this rather
exceptional. In the middle of the province Overijssel one weather station reported 4cm of snow.
Palindrome date (DD-MM-YY and YY.MM.DD)
Today is a palindrome date when written
according to the DD-MM-YY format: 22-11-22 and the YY.MM.DD formats: 22.11.22.
The previous such date was November 12, 2021 and
the next will be November 3, 2030.
Going into the city
I went biking to the city center. I walked to Fotogalerie Objektief where I saw
the exhibition Bomen in het park (Trees in the park) by Ruth Lowie. I went to Concordia, where they did not have any new
exhibition. I looked at the books at the low round table in the middle of the
exhibition Doublet: Thijs Ebbe Fokkens & Silke Schönfeld and
I made notes of the titles of two of them: The Immortality Key: Uncovering
the Secret History of the Religion with No Name by Brian C. Muraresku and
being aware of being aware by Rupert Spira. I also visited bookshop
Broekhuis, where I spend almost an hour looking at the new arrives. When I
noticed that the sun was about to set, I decided to go home, to enjoy the last
light of the day while going home. On my way home, I took the following
picture on the 'square' called Usselerplein, there where the Usselerweg ends
at the Denneweg and continue into the Zweringweg
(position in street view).
Book
At 16:57:20, I bought the book Geschiedenis van de moderne literatuur
written by Herman
Brusselmans in Dutch and published by Prometheus in 2021,
ISBN:9789044648904, from bookshop Broekhuis
for € 17.95.
