2010年10月分記事へのエム・ワイ君の感想 (M.Y.'s Comments on October-2010 Articles)

In Japanese only

 M.Y. 君から "Ted's Coffeehouse 2" 2010年10月分への感想を11月28日づけで貰った。同君の了承を得て、ここに紹介する。青色の文字をクリックすると、言及されている記事が別ウインドウに開く。

1. 水彩画「夏木立」(9月掲載分)、水都の一景

 堺市役所本館エントランスホールで開催された美交会展(11月15日から18日)に、筆者が出品したものです。画題の選定には作者の趣向が感じられます。ツイッター友達の Chaira Maieron さんもこのブログを見て共通の趣味をお楽しみの様子。私もブログでこの傑作を鑑賞しました。実物は色彩表現に作者の苦心が感じられるでしょうが、ブログではかなわないことです。

2. バス旅行「秋のかやぶき音楽堂コンサート」


 妻とバス旅行「秋のかやぶき音楽堂コンサート」に参加した。バスは午前9時に JR 大阪駅前を出発した。まず、兵庫県篠山市にある兵庫陶芸美術館へ寄り、特別展「型が生み出す、やきものの美—柿右衛門・三田—」を見学した。


 コンサートの演奏者ザイラーピアノデュオ(夫妻)は、日本各地はもとより、世界各地で4手のための連弾アンサンブルとして活躍しているほか、世界各地で未出版や廃版になったピアノデュオ曲の発掘にも精力的に取り組んでいる。演奏曲目は、ロベルト・シューマン「小さな子どもと大きな子どものための連弾曲集 」より9曲、ヨハネス・ブラームス「シューマンの主題による変奏曲」など。帰途のバスの中で、ゲーテが好んだという植物の、ザイラー夫妻が増やした苗が土産として配布された。


3. 「浜辺の歌」、「故郷を離るる歌」

 前者は「歌声喫茶 in さかい」で、筆者が最近、「この歌の3番の歌詞を覚えたばかりだったので、リクェストしたのだ。リクェストの6割ほどは知らない歌だったが、楽しい時間を過ごした」とあります。私もこの歌は、小学生の時、町の小学校の合同発表会で女生徒が清らかな声で歌ったのを聴いて心に残りました。3番の歌詞はずっと後になって知りました。チェロ奏者のミッシャ・マイスキーが情感豊かに美しく弾いているCDをよく聴いています。後者については、10月26日づけ記事中、J. Tanaka さんとのツイート交換の項にあり、筆者のこの歌を好む理由が書かれています。Tanakaさんは、「上手な少女の合唱で聞くと不思議な感動を覚える」と述べています。私は中学3年の音楽の時間に習いました。歌詞、メロディーとも美しい歌で、中学卒業後、就職して故郷を去る友人には、「蛍の光」のように心に響く歌だろうな、と思って歌っていました。

4. ツイートなど

 先端の科学・技術、平和、友人との言葉の交換、引用、インタ-ネットの利用などについて、よくこれだけの情報が毎日提供できることかと、筆者の見識の広さと好奇心と処理効率のよさに感心しています。筆者のフォロワーの多くは外国の方だそうです。『iPad英語学習法』著者、湯川さんによると、「英語学習には英語ツイートが有効」とのこと。筆者もこれを肯定し、吉田兼好や泉谷閑示の文の各一節を自身で英訳した例(それぞれ、10月15日づけ10月1日づけツイッター記録 "Quotations" の項)を掲載しています。通じる英語能力があってこそ外国のフォロワーが増えるのでしょう。Tanaka さんの言葉「ただ今HPを拝見し、ツイッターも拝見しましたが、殆どが英文の高度な内容で、いったんたじろいでしまいました」の通り、難解な話もありますが、最新情勢や啓蒙的なものを楽しんでいます。

Yesterday, I went to see the November Festival of Kyoto University with my wife. We met our first daughter's family at the festival site. One of our grandson, who had entered the university this year, was selling cups of pork soup at one of the booths on Yoshida Ground with fellow members of the softball club, so that we each had a cup. There were many booths selling food etc., and the music was loudly played from the speakers. Such liveliness was quite different from the festival in my student days.

Copies of Vol. 4 of the magazine N-Free, published by the Execution Committee of the November Festival, were distributed free of charge. It consists of a total of 24 pages and carries a feature article of 5 pages, "Interview with Toshihide Maskawa." The Nobel-winning physicist Maskawa gives the following words to students: "I recommend discussing everything with the young people of the same generation as you, even all through a night. Then, you get much more things than are taught by your teachers or seniors." (The photo shows the sign of the November Festival at the north-east corner of Yoshida Ground, Kyoto University.)

[From Arjen Dijksman] I'm reading about Kikuchi lines (electron diffraction) and looking for bio about S. Kikuchi but don't find. Is there any in Japanese?

[To Arjen] The bio of S. Kikuchi in Japanese: . It's regrettable that there's no English version. I should be able to help you translate part of the bio on the above page into English, if you would like it.

[From Arjen] Great! Thank you. The bio of Kikuchi should also be available in English indeed. I will see if I can work on en.wiki.

[From Arjen] I created the wiki stub from what I understood with Google translate. Thanks again.

On the first day of the reunion, the organizer said, "For the museum visit of tomorrow, I chose 'Petit Louvre' Exhibition at Musee d'art Mercian Karuizawa. The exhibition has been well received, and the period in which it is held has been extended." So we thought that we would certainly go there. However, he added, "It's a pity that the museum is closed from October 25 to 29 in order to change the works for exhibition." He continued, "In Karuizawa, there is another excellent museum, the Sezon Museum of Modern Art." Hearing this, we thought it was also a smart plan to visit there. However, he said, "The museum is closed on Thursdays." Thus, we actually went to the Tasaki Museum of Art by the small bus of the hotel, arriving there shortly before the opening time. But alas! The museum remained closed after the opening time in spite of the information that it was closed on Wednesdays. Reluctantly, we took the bus again to go to the Karuizawa Museum of Picture Books.

The Museum of Picture Books is located in a large park, Muze Forest, together with another facility, the Erzgebirge Toy Museum of Karuizawa, and consists of separate buildings of the First Exhibition Hall "Berg," the second Exhibition Hall "Turm," Picture Book Library "Hügel" (the photo above), and so on. At the First Exhibition Hall, a special exhibition, "Animal picture books: The fantasy of anthropomorphic animals" was being held. It was such a lovely museum for both children and adults to appreciate that I wished to have a similar one in Osaka Prefecture where I live. The tickets we bought were also valid for the Toy Museum. However, we did not have time to see that museum and went to the place for lunch.

The original schedule for the second day of the reunion of Kindaijihō-kai was that we would enjoy cycling or visiting museums in two separate groups by preference of each person. Because of a low temperature and rainfall, however, cycling was canceled. Before breakfast, it did not yet begin to rain, so that I could manage to take some pictures of the typical scenery of Karuizawa in the hotel garden (the photos above show the back garden of the hotel).
