Le Nozze di Figaro
This afternoon, Andy spend some considerable time
listing to the opera Le
Nozze di Figaro by Mozart.
This made me think about the question, what is the minimal intelligence (IQ)
for intentional and attentively listening to an opera? Some classify operas
as the most complex form of classical music. However, in the paper
Why More Intelligent Individuals Like Classical Music by Satoshi Kanazawa
and Kaja Perina it states: At the same time, preference for opera, another
highly cognitively complex form of music, is not significantly correlated with
intelligence.
I prefer to listen to the
Boom Room while trying to understand the paper Minimal Phenomenal Experience by Thomas Metzinger. Or I listen to the presenation he gave about the subject, while cleaning up my email
inbox and, later, writing this.
Finals 2018: Second visit
This morning, I visited the AKI Finals 2018
exhibition again. Now on my own. I arrived
early and it was very quiet, giving more time to absorb and enjoy everything.
It made me realized, I had missed some things last
Friday. I found the works of the following graduated students noteworthy
(in the order I encountered them):
- Mike de Jong. (Later, I inquired
if the book he has on display is for sale.)
- Maria Britze.
- Benedetta Guidi.
(Later, I contacted her to talk about buying a work from her.)
- Eline van Hove. I read that she
combined her study with studying math at the University of Twente.
- Marlijn van Zadelhoff. I talked a little with her. She works mainly with
glass.
- Liesbeth Piena.
- Lorraine Etimiri. (Actually, mainly her individual 'business' cards.)
- Lex Chan. (Talked a bit with him. He has a picture of Kira Fröse and her works on display.)
- Nadie van Wijk. I ordered the little
book Het feest der mislukking.
- Laura Homölle. I
ordered the book WE ARE AKI.
Yesterday, when seeing a drawing of a the B4 orthographic projection
of the tesseract
(the first hypercube), I thought about how it would look it pentagram would be extended with 'cubes'. Today, I came up with the
following drawing:
33.35%
One third of all 428,362 sets of equations for
the the Irregular Chocolate Bar problem for
the problem of finding 22 unique integers which can be divided in up to and
including 10 partitions, has been processed. Now at 33.35%, 7380 unique
solutions have been found. It seems that the processing of an equation is
taking more time and that more solutions are found. This makes it hard to
estimate when all sets of equations will be processed.
This afternoon, I first went to Concordia for the part of the AKI Finals
exhibition that I had not seen yet. I liked
the works of Pjotr Stam. Next, I went to the AKI
building. At 17:08, I bought the book Emma & Thomas that Mike de Jong had on display for € 20.00. It is one of five he
had made. I met with Benedetta Guidi, looked at her works, talked with her
about them, and thought about which of her works I want to buy. I also talked
a little with Eline van Hove, mainly about discrete mathematics.
Watercolour by Benedetta Guidi
Last Thursday, I met with Benedetta Guidi and looked at her works, which are about the intimacy of
two people meeting. Yesterday morning, I let her know my decision to buy
one of her
works. I like this work, because on one hand it is very realistic, and on
the otherhand it vague, very colourful, almost abstract, if you do not
recognize the figures that are in it. The male figure is less clearly visible
as in more of her works. This afternoon, I went to the AKI to collect the
Untitled work.
At 17:54, I bought the following two comics from charity shop Het Goed for € 1.95 each:
- Ravian: de vierde dimensie written by Pierre Christin, illustrations
by Jean-Claude Mézières, written in Dutch, published by
Dargaud in 1983, and translated from Les Mauvais Rêves written
in French, ISBN:9067932183.
- Ravian: De wees van de sterren written by Pierre Christin,
illustrations by Jean-Claude Mézières, written in Dutch,
published by Dargaud in 1998, translated from L'Orphelin des astres
written in French, ISBN:9067934844.
Royal Academy of Art
I went to the Graduation 2018 exhibition
at Royal Academy of Art in The Hague. I first
went Amsterdam, where I went to bookshop
Scheltema and bookshop Het Martyrium. At
both bookshops I did not buy anything. In The Hague, I payed short visits to
the American Book Center and bookshop Paagman. At 14:14, I arrived at the
Royal Academy of Art and stayed there till 19:50. I am almost sure, I missed
some rooms, because it is a rather compex building. I found the following
graduates noteworth (in the order that I encountered them or their works):
At 19:20, I bought Graduation Catalogue 2018 for € 12.50.
Gerrit Rietveld Academie Finals 2018
Today, I went to the Gerrit Rietveld Academie Finals 2018
exhibition. I found the works of the following
graduates noteworthy (in the order I encountered them):
At 15:39, I bought one of the last available copies of the magazine that is
a remake of the British Vogue March 2018 issue, for € 18.00.
Rain
At 14:45, we had some rain, the first time since
June 25, when there was 1.2mm of rain according to
data from Royal Netherlands Meteorological Institute for station 665 in Enschede.
This morning, I spend some time cleaning up leaves that had fallen from the
tree in our garden. At the moment we are in the 5%
dryest of years on record. In the past weeks, our
magnolia has had some flowers, but it seems that they wither before they
are fully open.
Jessica Segall
In the evening, I was in the city with a friend, and we went to Concordia
where there was an opening an exhibition by
Jessica Segall. We were a little
late for the artist introduction and joined at the end of Q&A session.
Book
At 11:01, I bought the book Kunstopdrachten van de Rijksgebouwendienst na
1945 written by Wilma Jansen (in Dutch) and published by Uitgeverij 010 in
1995, ISBN:9789064501951, from charity shop Het Goed
for € 4.50.
Kunst & Koffie
This afternoon, I went to the opening of the exhibition Kunst & Koffie (Art and Coffee in English) at
Concordia. The exhibition consisted of works from their art for loan
collection. Among the works in the art for loan collection, I found the work
Zonder titel III by Hill Boxem the most interesting.
In the evening, I opened the window to listen to the thunder outside. I also
saw some lightning. We did get some drops. It seems there was some rain last
night (less than 0.5 mm, it seems). That is the first rain since July 9.
Rijksmuseum Twenthe
I went to Rijksmuseum Twenthe. I first went
to see the exhibition Paula Modersohn-Becker with work from her and other artists. I
liked the work Staand vrouwlijk naakt, from about 1899, the most. Next I
walked through the exhibition of Bernard Heesen, which I did not find
very interesting and went to see the exhibition Schatkamers,
which included the following works:
Next I watched the woodworks exhibition by Luuk van Bindsbergen. Finally, I went to see the exhibition
Ars Longa, which included the following works:
- Paring / copulation, 1961, by Aat Veldhoen
- Paring / copulation, 1962, by Aat Verlhoen
- Untitled, 2014, by L.A. Raeven.
- You - Me, 1998/1999, by Frank van Hemert.
- BJA: The prince of fine art, 2016, by Berend Strik.
- Untitled, screen print 1966, by
Peter Struycken.
- Untitled, 1973, by Peter Struycken.
- Trames, screen print, 1965, by François Morellet (multiple parts).
- Random objectivation V72-140S by
herman de vries.
- 10 meters of sound, 2018, by Philip Vermeulen.
- jij en ik / you and i
by Karin Avink.
- Waldrand 20-10-17 by Armando.
At 15:31:59, I bought the catalogue Ars Longa, vita brevis - Human life in
nine episodes written by Arnoud Odding in English and published by
Rijksmuseum Twenthe in 2018 for € 15.00.
I went to the opening the exhibition Beyond
the grain at photo gallery Objektief with works by Lena Paßlick and Lex Chen. Both are also invited for the Best of Graduates 2018 exhibition at Ron Mandos in Amsterdam, which opens
at August 3.
Dark cloud
At the end of the day, a colleague of mine, mentioned that rain was coming. It
was indeed, and I decided to leave for home. When I came outside at one side
of the building, there was a blue sky and the temperature was above 30°
Celsius. When I came to the other side of the building, I saw a large dark
cloud approaching. I stopped to take a picture. About half way, I felt some drop of rain, while already
hearing thunder overhead. I put on my rain poncho, just to be prepared for a
heavy shower, but it did not happen. Later, at home, it started to rain a
little stronger for a few minutes, barely enough to make the streets wet. A
little up North, in Losser, they got much more rain, up to 57mm, resulting in
some roads being flooded.
Blood moon
Yesterday evening, just before ten in the evening, I biked around, to see
from which locations the moon is visible, in order to know, from where I should
be able to see the lunar eclips this evening. Just after ten this evening, I was on a
nearby bridge, but could not discover the moon, probably because the sky was to
light. Half an hour later, I went outside again, and around 22:35, I took the
above picture from a location not far from my house. I took the picture with
my Panasonic Lumix DMC-TZ8 using the
stary-night mode from a simple tripod at maximum optical zoom. The picture
shown is but a small part of the actual picture. Later, I took some more
pictures, when the moon started to come out of the core shadow. Some of the
looked like the pictures, I took
on September 28, 2015.
Persistent 'balanced' tree revisited
Last Tuesday, I started to work on an implementation of a set of integer
intervals using a tree structure. This made me return to the persistent
balanced tree, I worked on in January. In the past
week, I worked on improving the code, resulting in a new version. When MAX_SHARED is not defined, it does keep the
tree balanced, in the sense that the difference in height between each left and
right subtree of a tree is at most one. In case MAX_SHARED is defined,
this is not the case, whenever balancing would require to no longer share trees
that could still be shared. This reduced the memory usage with the introduction
of some imbalance.
