Today, just like last year we went sailing on
the Fluessen lake with a large part of our company. At first the plan was
to sail from Lemmer to
the IJsselmeer but
plans where changed because of the strong wind (seven on the scale of
Beaufort) and rough conditions on the lake. Instead we left from Elahuizen,
the same place as previous years. After we sailed for about twenty five
minutes one of the cables connecting the helm and the helm wheel broke,
and the captain decided to lower the sails and continue the rest of the
trip on the engine. In Stavoren we had our lunch and after a short walk
over the dyke to see the waves on the IJsselmeer, we went back. The cable
had been repaired and we sailed back with only the jib. The captain allowed
me to stand at the heml wheel for about 80% of the trip.
09-09-09 and twin chestnuts
Today, is one of these special dates
again. Of course, there were more weddings today than on a normal
day. A local newspaper started a contest for the best picture
taken on 09:09 in the morning. At that time, Li-Xia
and I were biking into the city to look for some shoes for
Andy. When we discovered that the shops
where still closed we decided that I would go to my office. On the way
I found two chestnuts inside a single
shell. I took them with me and put them on my desk in the office.
The last time got into
Metamath, a computer-assisted
proof checker, I thought about an alternative that would have
a little more 'structure'. Yesterday, I came across the
Ghilbert language as invented by Raph Levien. He wrote a collection of Python programs to transform Metamath files
to Ghilbert and to verify Ghilbert proofs.
Dan Krejsa wrote Shullivan, a verifier written in C. Proofs in Ghilbert is
more compact than the equivalent Metamath proofs.
The file set_mm.gh gives the Ghilbert representation of the
Metamath set_mm proofs of October 17, 2006 converted by

In the past days the GOGBOT festival
was held in Enschede again. Thursday evening, I already looked around
the central square "De Oude Markt" in Enschede. Today, Li-Xia and I first went to the Rijksmuseum
Twenthe. There was only a small exhibition with respect to the
festival. We did see some paintings from the Red Storm exhibition with works
of young Chinese artists.
Next we went to Tetem 2, where watched "Probe" by Boris Debackere. We looked
at some other exhibitions of the festival, which I did not really like.
When we came back to "De Oude Markt", Bastiaan Maris just ignited his
pulse jet. (See also YouTube part 1). We also played with the
by Jonas Vorwerk. The refrigerators
from the Coldwar project by Topotek were quite funny. The work by
Saygin Soher made me think about
the art of Rinus Roelofs.
In the evening, Annabel, Li-Xia, and I also walked
around. We watched another ignition of the pulse jet and we also looked
at the drumming robot "Stickboy Model RC 1007" by Robocross. Especial the movements of the head made it almost look like
a real drummer. Very funny. Annabel took a picture of the Punktrabant made by Olaf Mooij.
Ninth Dutch Kabuki day
Today, the ninth Dutch Kabuki day was held. Li-Xia,
Andy, and I went to the South of the country
to attend this day, which was organized in the Ronald McDonald Kindervallei
aan de Geul. The colorfull building is designed by Heinz Springmann in
the tradition of Friedensreich Hundertwasser. We left at 6:50 and it took us almost three
hours to get there. But it was worth the drive. The weather was very nice.
It was good to meet some other parents again. Andy is now among the older
children. The youngest child was 20 months old. Professor Connie Schrander-Stumpel
told us about the scientific results of the past two years. There were no
significant break-throughs. Also the analysis of the blood we as parents donated
two years ago, did not reveal any clues about
the cause of the Kabuki Syndrome. It is not very unlikely that the syndrome
is caused by a single mutation of a certain gene. In the afternoon we had a
great lunch (including bread and ragout). There was ample opportunity to share
with other parents. In the afternoon we had some more presentations and discussions.
At the end the children performed a small piece of drama for us, which they had
been taught by some 'clowns'. Around half past six we left for home again.
Today, according the date notation that places the
day before the month, is a double date. It is also the birthday of one
of my sisters.
The Meaning of Life
This morning, I finished reading
the book "The Meaning of Life" by Terry Eagleton, which I started reading on September 12,
two days after I bought the book from De Slegte for € 7.95.
(Watch this short introduction to the book by the author.)
It is a pretty to read book with many great insights, but
I failed to clearly see the great line. On page 163 the
author quotes statement 6.44 from Wittgensteins
Tractatus Logico-Philosophicus, which, translated to
English, reads: "Not how the world is, is the mystical,
but that it is." Eagleston thinks that perhaps this
statement means that we can speak of this or that state of
affairs in the world, but not of the value or meaning of the
world as a whole. Funny, but that is not what I read into
that statement. I thought that Wittgenstein states that the
fact that something exists, instead of nothing at all, is
the most mystical. I guess not everyone realizes the significance
of this fact, that it is far more logical that nothing would
exist at all. I formalized this in 2003 as the two big questions
This afternoon at 16:53:24, I bought the following books from
Henry and June
This morning, I finished reading the Dutch translation
of Henry and June
by Anaïs Nin. I started reading this book on August 10, the day I bought
the book at 17:49:59 from De Slegte € 3.
I have read this book side by side with the Dutch translation of
The Diary of
Anaïs Nin Vol. 1 (1931-1934) and putting the common phrazes between
brackets and marking with the page numbers from the other book. This required
a very intensive method of reading and rereading, because there are large
gaps between these two books that are based on the same original dairies of
Anaïs Nin. I am getting the impression that Henry and June,
which was published after the death of Anaïs Nin, is an heavily editted
version by the hand of Rupert Pole, because it often uses a very different
style than the earlier version and feels less like a diary. It is sure that
Henry and June is far more explicit, but to call it an erotic novel,
is really too much, because it mainly deals about the emotions of Anaïs Nin
and her dealing with her past. In the earlier dairy nothing was said or even
hinted about the romantic relationship she had with Henry Miller and other man
in her life. I found it an interesting book to read, because it shows that
reality is often far more stubborn than we think.
This evening, I went to the university to play Go.
I was the first to arrive. Next came Taco and Rudi. Rudi proposed that
I would play against Taco and that he would watch us. We agreed that I
would get seven stones ahead. Not long after we had started, Huub arrived
and he played against Rudi. After they finished their game, they watched
our game. We finished around eleven after having played for almost two
and half hour. In last half of the game I made some big mistake and lost
a small group in a corner. Rudi felt that I lost a lot of points in the
end game. I lost with 52 against 41.
