[From chiamai] Hi! I finally dared to post a photo. Not good, but gives the idea of me not sleeping because of rain and stress :)
[To chiamai] Hi, It's an artistic photo with a flavor of abstract painting. Did you get it with a long exposure?
[From chiamai] Thanks for your kind words. I used a long exposure, but with an automatic setting in my camera. I have also taken 'normal' pics, but this corresponds more to my being half-asleep and a bit angry at the rain that woke me up.
[To chiamai] I see. Today I noticed your retweet at quite an early time of your zone. We also had rain this morning after a long while.

ウォーキング・コースの風景 11 (Scenery in the Courses of My Walking Exercise 11)
写真は堺市西区の南部に残る田園。2010年8月28日に撮影。もう稲穂の香りが漂っていて、幼い頃に住んだ田圃の多い小さな市(石川県七尾市。その後、村を併合して面積は拡大された)を思い出させた。写真中央の道の先を、昨日掲載の写真の和田川が横断している。
The photo, taken on August 28, 2010, shows rice fields remaining in the southern part of Nishi-ku, Sakai. There smelled ears of rice already. It reminded me of my childhood when I had lived in a small city (Nanao, Ishikawa Prefecture) with a lot of rice fields. At the forward of the road lies Wada River in the photo posted yesterday.

About Books
Began to read Marcia Bartusiak's The Day We Found the Universe (Vintage). —"While notorious for being a man of few words .." (p. x). You may ask if Dirac appears here. No, this man is Calvin Coolidge, the thirteenth president of the United States.
[madgestar's words came between my previous tweets about Bartusiak's book (sent in two), as follows: "Popular science books take off: a big bang in physics publishing," by TomChivers*, Telegraph. I wrote about this happening:] This is quite interesting, because the article cited writes about the publishing phenomenon of "the soaring popularity of popular physics books" like the one I am reading.

About Arts
Yesterday, my wife and I went to see the 1934 German film "Abschiedwalzer: Zwei Frauen um Chopin" (Japanese title "別れの曲"), which had been shown in Umeda, Osaka, to commemorate the 200th anniversary of Frédéric Chopin's birth. It rather comically depicted Chopin's love of his motherland Poland and two women, Constantia Gladkowska and George Sand.
About Physics
[In reply to materion's words, "Fundamental laws of physics are same everywhere. If the fine-structure constant is not same everywhere, this would mean that it's not a constant."] You're right, indeed, but Dirac would be pleased in heaven.
[From materion] I do not remember if Dirac expressed something about variation of fine-structure constant.
[To materion] I mean Dirac large numbers hypothesis. It does not refer to fine structure constant, but the gravitational "constant" was assumed to be inversely proportional to the age of the universe.
[From materion] Thanks for pointing out Dirac's large numbers hypothesis. Gravitational constant must be in some way interconnected with the fine-structure constant.

About Universe and God
"Are we living in a designer universe?" Telegraph. —It is interesting that John Gribbin wrote this article just before "Hawking's denying God's creation fever." (I wrote the same comment on the Facebook page of Gribbin. He replied, "Well spotted!")
"Is physicist S. Hawking right that physics, not God, created the universe?" Poll, Gardian Yes: 37.5%, No: 62.5%. What do you think?
[From F414] God was created by imagination; the universe by energy. The universe came first.
[To F414] Yes, I think so too. I wanted to hear rather comments on the result of the poll. When I saw the result about 8 hours before the closing of the poll, "Yes" was 85%, and I thought the opinion of the British was sound. However, I was surprised at the final result.
[From F414] God is comforting; the unknown is not. Personally I love the unknown, the unthought, the not yet imagined; but that's just me.
[To F414] Science seeks for the truth of Nature; religion, the peace of mind as you mean by the words "God is comforting." From this point of view, the poll itself (or Hawking's saying) is nonsense. There should be no debate between science and religion.

[To chiamai] Hi, It's perhaps morning there. I woke up from a nap after lunch.
[From chiamai] HI! Yes it's morning, and I'm up a bit later as it's Sunday. Have a nice afternoon :)
[To chiamai] Your time zone is UTC+2 hours including +1 hour of daylight saving time (DST), right? Ours is UTC+9 hours. In what months do you use DST?
[From chiamai] Right, we are currently UTC+2 hours. DST in the European Union is used between the last Sundays of March and October. What about Japan?
[To chiamai] We used DST from 1948 to 1951 but don't use it now. Only in the most northern area, Hokkaido, it is used experimentally.

[To itadori3] サルスベリの木の肌は、サルがすべりそうなほどツルツルなので、その名があり、百日紅と書くのは、花の咲く期間の長さからの別名を当てているのでしょう。
