Ayaan Hirsi Ali

According to this press release, USCIS Director Emilio Gonzalez presented Ms. Ayaan Hirsi Ali with her green card on September 25, 2007, during which he said: "Today, we welcome her to the United States as a permanent resident. We welcome her to the protection provided by the U.S. Constitution and encourage her to continue speaking out regarding those issues she feels passionate about."

However, yesterday, she returned in the Netherlands, because the Dutch government announced that they no longer want to pay for the cost of her security while is abroad. Neither the Unites States nor the employer, American Enterprise Institute for Public Policy Research seems to be willing to pay for her security.

14 balloons

This morning, we found 14 balloons on the table in the living room (picture). These were put there by Annabel for our 14th wedding anniversary. She had set her alarm at five o'clock.

In the afternoon, Li-Xia, Annabel, Andy, and I went to the city and we had a dinner at Camel consisting of some donner kebab, falafel, salad, and fried potato slices. Andy did not want to eat anything, but he sat very quiet in his chair. It seems he is used to wait while others are eating. Once in a while he would look at our dishes to see if we were already finished our meal. Afterwards he wanted to visit some toy shop. Because it was close to closing time (five o'clock), we had to rush. Whenever he saw some Pokémon related toy he would greet is goodbey, because tomorrow is his tenth birthday.

4 dimensions

Today, I read an item on Slashdot about the time dimension becoming space-like, in reference to the scientifical publication "Is the accelerated expansion evidence of a forthcoming change of signature?". All highly speculative. But it made me think about the idea that I got some weeks ago that time in our three-dimensional world is maybe like an expanding four-dimensional sphere. That would imply that time has a different direction at each location in space. The best way to compare this, is to look at a wave in a pond that occurs when a stone is dropped in the pond. That wave has the form of an ever expanding circle. The circle could be viewed as a one dimensional space. The "time" on each point of the circle is moving in a different direction. This too is all highly speculative. I wonder whether such a model would be consistent with general relativity, let alone special relativity. Maybe such a model would imply that red-shift are approaching to infinity at the end of our visible universe.

Playing Go

This evening, I went to the university on my own (because Annabel did not want to go) to play Go. I had to wait some time before someone else arrived. First Rudi arrived and I asked if we could analyze a game that I played on Its Your Turn. Just before I left, I had copied the game record by hand, and it appeared that I had made some mistakes. But we managed to find them. While we were doing this, Marcel arrived. They found several big mistakes in the game made by my opponent and me. (A PostScript and a SGF file with the remarks). Rudi suggested that he would play simultaniously against Marcel and me. He played rather quick with Marcel and the managed to finish two games in the time I needed to finish my game. I had been given eight stones ahead, which should have been nine. Although Marcel remarked in the middle of the game that my position looked strong, I lost the game with 70 points. Afterwards we spend some time talking and analyzing the game. One and half year ago, I never liked it when others started to analyze my game and telling me how to deal with certain issues. Now it seems, I can remember large parts of the game myself and like to ask questions about how to deal with certain situations. Marcel thinks that I have become 10 Kyu stronger since I started to play at the club.

Curly kail hotchpotch

Today, it is the thirteenth birthday of Annabel. She wanted to eat curly kail hotchpotch for her birthday. Because she had three friends visiting, I had to made a lot. One of the friends did not like curly kail, so I made some green beens for her. I boiled the curly kail in a separate pan because everything did not fit in one pan. I made two pans with hotchpotch. I mixed the pork cut in cubes with the biggest of the two pans, because I did not want to eat the pork. It looks like that everyone liked it, because we almost finished everything. I think I cut about three kilo of potato.

Blood proteins may diagnose Alzheimer's

Today, I read an interesting article from the BBC about a blood test that could identify Alzheimer's disease. They found that the levels of 18 proteins are different. These proteins are are also involved in the production of new blood cells, immune processes and the death of cells at the end of their natural life cycle. Dr Wyss-Coray said: "Our hypothesis is that there is something wrong with the production of certain blood cells, which may be needed to clear that stuff that accumulates in the brain in Alzheimer's disease." Yesterday, I came across Peripheral ethanolamine plasmalogen deficiency: a logical causative factor in Alzheimer's disease and dementia. I do not know whether these two findings are related. If I understand it correctly, the chemical ethanolamine is not a protein. Ethanolamine also refers to a class of antihistamines containing an ethyl-amine group attached to a diphenyl structure.

This morning, when I biked to my office, I was surprised by a complete rainbow with in the background a blue sky with some clouds. I immediataly took some pictures (combined) and when I was finished it started to drizzle.

A bottle of wine

This afternoon, I went to the University to talk with some students who for a certain course have to design a device with a GPS receiver which could support people with early stages of Alzheimer's Disease (or other forms of memory problems) in their daily activities such as visiting friends and doing shoppings. It was a very interesting talk. Afterwards, I was given a bottle of wine as a reward for my cooperation. One of the greatest challenges with defining such an interface is that most people with these type of memory problems have often great troubles with learning to use a new device. The interface needs to be very intuitive. We concluded that it should make extensive use of images and pictograms.

Path of the Shell

Yesterday evening (actually, early this morning), I finished Uru: Path of the Shell. Especially during the last part, I made use of the hints, because I got bored.

Last ten unsolved square tiles

Today, I finished the write-up of the proof that the last ten square tiles do not have an infinite solution using all possible tiles in the set. With this, I think, I have determined of all possible square tilings with two values, whether they have an infinite solution or not.

This afternoon we went to catch Andy from the place where he says every other week for the weekend. We were told that when they had pancakes yesterday, Andy kept on asking for more until they were finished. He ate at least four of them. This is one of the first time, he himself has been asking for more to eat of something. Of all places, that place is where he eats the best. The strange thing is that there he refuses to drink his liquid formulea, whereas at home it is the only think he wants to drink.

Playing Go

This evening, Annabel and I went to the university to play Go. We arrived as the first, although it was already half past eight. Luckily, we had brought a playing board, so I challenged her for a game. She wanted to eat "bitterballen" (a type of croquette served as an appetizer) and suggested that I would pay her these if she would win. We played on a 19x19 board. Not much later Araldo and Rudi arrived, and they started to play with each other. At the end of middle game, after I lost some stones, I felt I had lost and I resigned. Annabel went to order the "bitterballen". We continued the game, and although I still had some chance to win the game, I made some big mistakes, because I was playing too fast, and lost the game. She challenged me for another game on a 13x13 board. Although I was determined to win this game, I lost it again because I made some stupid mistakes, when I played too reckless. I challenged her for another game. She complained she felt tired and was not playing very strong anymore. I won this game with ease. Then I waited for Araldo and Rudi to finish their game, because I wanted to ask their opinion about a game that I played on the It's your turn. (A PostScript and a SGF file with the remarks). We left around ten to eleven and Annabel complained that it was too late. Torrow, she had a test for French.
