Air Crash Investigation

This evening, I watched Air Crash Investigation episode 1 of season 10 "Who's In Contol?" about the crash of Turkish Airlines Flight 1951. (YouTube: 1 of 4.) I noticed that they used some fragments from Turkish Airlines Flight 1951 Accident Animation Dutch Safety Board, but I am surprised that they did not go into the details of what happened in the final ten seconds, which are also mentioned in this animation. It is important to notice that the final report from the Dutch Safety Board states that the pilots should have been able to control the plane when the stick-shaker was activated. During the episode it is remarked that humans are good a making split second decisions. Now it seems that the co-pilot, who was at the controls, responded properly to the stick-shaker, but that his response was aborted when the captain took over the contols. Next the captain failed to perform the correct steps. Had the captain not taken over control, the plane most like would not have crashed. I had always thought that Air Crash Investigation was about going to the bottom of the cause, but it seems that they failed this time, even though I think that Joseph Sedor, working for the NTSB, should have known the U.S. Summary Comments on Draft Final Report of Aircraft Accident Turkish Airlines flight 1951.

When I came home, I found that many flowers on our magnolia had opened and one could say it started to bloom again.

Hamiltonian Cycles

Today, I received an email from Artem M. Karavaev informing me about the new result with respect to the number of Hamiltonian Cycles in graphs of the form PmxPn and CmxPn, which he has published on Flow Problem. This extends the results I found with respect to counting Hamiltonian cycles. Interesting to see how others follow-up my research and have gone much further than I thought would be possible. Karavaev is working on a paper dealing with the results.

De Slegte Nijmegen

This afternoon, I visited bookshop De Slegte in Nijmegen for the first time in my life together with Susan who lives in Nijmegen. On the way to her home, I took a picture of a tree in blossom. (My GPS tracks of today as KML file or in Google Maps.)

Bob Dylan: Intimate Insights

At 13:14, I bought the book Bob Dylan: Intimate Insights from Friends and Fellow Musicians by Kathleen MacKay (ISBN:9781847721341) for € 4.00 from bookshop De Slegte.


Last Sunday, I read Lynch's Dune, 1st Draft Screenplay. This screenplay stays quite close to the key scenes of Dune by Frank Herbert. It deals with only the first half of the book as it was the idea to cover the book by two movies. Although the screenplay really focused on the core of the story, I felt that it was quite boring. Yesterday, I started to read Dune for the fourth time, the first time in English, curious about what made me read the book so often. (I bought this copy on April 3, 2010 for € 4.00.) Maybe one reason why I felt that the story is boring, is because the story was not really around Paul, the main character of the book. In the first part of the book he is still having a rather passive role in the story.

If I ever were to open a restaurant, I would present my dishes in layers. The nice thing about presenting a dish in layers is that often you cannot see the bottom layer, which makes it a kind of surprise when you start eating the bottom layer through the other layers. The bottom layer of the dish consisted of bits of chicken in Chicken Tonight Satay Sauce. Then a layer of boiled string beans and some rice on top. Normally, I would have put the sauce on top, but because the sauce was left over from yesterday, I had to heat it up in the microwave, and got the idea to put the beans and the rice over it. I found it quite interesting and when I served for the third time, I decided to take a picture, which explains the 'spots' of sauce on the edges of the plate.

Perelman interview

According to some article, Grigori Perelman has given an interview to the Komsomolskaya Pravda newspaper. He has agreed to be part of a documentary about the cooperation and the struggle between three major mathematical schools in the world: the Russian, the Chinese and the American ones. During this interview he said: "I know how to control the Universe. Why would I run after a million, tell me?" According to the article some seem to take this statement literal, but most likely Perelman means "to control" in a figurative/mathematical sense.
