軽井沢で1 (In Karuizawa 1)


 さる10月27、28の両日、軽井沢で旧金沢菫台高校新聞部の同窓会「菫台時報会」(第14回)が行なわれ、参加した。出発前に滞在する日々の軽井沢の予想気温をインターネットで調べると、最高で5度となっており、冬装束を準備して出かけた。それほど寒くなければ、早めに会場へ行って、散策を楽しむところだったが、予想気温の低さに驚いて、集合時間に近い夕刻に到着する新幹線の列車を選んだ。

 出席予定者は12名だったが、間際に3名のキャンセルがあり、「ホテル鹿島の森」に参集したのは、盛会だった頃の半分以下の9名だった。しかし、政治・経済・社会問題を声高に論じてあきない口達者な連中が何人もいて、相変わらず賑やかな会合だった。[写真はホテル鹿島の森の前の庭園。28日の朝、撮影した。]

On October 27 and 28, I attended the 14th reunion of the newspaper club of the former Kanazawa Kindai Senior High School (the reunion is named "Kindaijihō-kai") held in Karuizawa. Finding on the Internet that the highest temperature expected during our stay in Karuizawa would be 5 degrees centigrade, I went with winter clothes. If it had not been so cold, I would have enjoyed walking in Karuizawa before the meeting. However, I was surprised to the temperatures expected and chose the bullet train that arrived at Karuizawa close to the meeting time in the evening.

The number of people who initially entered in the list of participants was twelve, but three persons made cancellation. Thus, the number of persons actually came to the site of reunion, Hotel Kajimanomori, was only nine (less than one half of the number at the best time of the reunion). However, there were some participants who liked loudly and tirelessly to discuss political, economic and social issues, and the meeting was lively as ever. The photos above, taken in the morning of 28th, show the front garden of Hotel Kajimanomori.

"The evolutionary origin of laughter," Technology Review Physics arXiv Blogs (October 29, 2010). —"A new theory attempts to explain one of the great puzzles of evolutionary biology: why we laugh." [Retweeted by Neil Gunther and Tim Jones]

[From Tim Jones] Interesting, but the explanation of humor would be more so.

[To Tim Jones] The evolutionary origin of humor? It might come after the establishment of the theory on the origin of laughter. Let's expect it.

[From Tim Jones] Yes; it could well be. The article reminded me that laughter can be separate from humor (nervous, embarrassed, etc.).

[To Tim Jones] Yes, laughter comes not only from humor but also nervousness and embarrassment. The Japanese often show a smile for the last reason.

[From Tim Jones] I know! My boss was Japanese between 1992 and 1996 (from Nippon Steel). I just did not like to mention it (embarrassed laughter ;-).

[To Tim Jones] It's interesting (or embarrassing) that you learned embarrassed laughter from contact with your former Japanese boss.

[From Tim Jones] It was a very multi-cultural environment in Brussels. I learnt a lot there from different cultures/nationalities. If only everyone could have the same experience, we would all understand each other better. The world is getting there . . . slowly.

[To Tim Jones] I also liked to have multi-cultural environment on the occasions of international academic meetings. Thus we, scientists and engineers, might be better diplomats than the actual ones who work in the fields of politics.

[To Chiara Maieron] I should be glad if you could enjoy looking at my second watercolor work "A Landscape of the City of Water" for the exhibition to be held next month.

[From Chiara Maieron] At a quick look it looks beautiful! I'm now going to Lyon tonight, to fly to Seattle tomorrow. I'll check your work again from there.

[To Chiara Maieron] Thanks for your kind words about quick look at my watercolor. Have a nice flight and good days in Seattle!

2010年9月分記事へのエム・ワイ君の感想 (M.Y.'s Comments on September-2010 Articles; in Japanese only)

 M.Y. 君から "Ted's Coffeehouse 2" 2010年9月分への感想を9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. 郷里・金沢

 金沢の街の風景・名所の美しい写真と筆者の描いた絵を添えて、9月13日から15日の3日間が、懐古風にまとめられた旅行記です。A 先生と古くからの友人、合わせて3名の方々と会い、その合間をぬって、ありし日の郷里・金沢を偲ばれたこの旅は、いつまでも心に残るものでしょう。10回の連載には、生活の場としての金沢のよさも紹介され、読んで、見て、楽しいものでした。

 昨年米寿を迎えて金沢市などから祝福を受けたA先生[小学6年生のときのクラス担任]は、手術すれば失明の恐れもある厄介なタイプの白内障になり、医療技術の発展を待って手術を見合わせておられるとのことだった。しかし、精神的にはすこぶるお元気で、差し上げた私の自費出版書の内容などを中心に大いに話がはずんだ。

 K.T. さんとは、14日にホテルの和食堂で昼食をしながら、共通の友人 Y.A. さんの入院、その他について、2時間ほど話し合った。

 高校同期の友人 K.Y. 君とは15日に、ホテルの喫茶室で10時半から12時少し前まで愉快に語り合った。

 13日に A 先生の家を辞してから、私の母校・菫台高校まで歩く。高校1、2年生のときに私の住んでいた家が、少し行ったところに、いまもその頃とほとんど同じ形で立っていた。

JR金沢駅東口の「鼓門」、木製で、2005年に完成。その奥に巨大な総ガラス製の半球形天井「もてなしドーム」が続く。旧市街は駅の南東に広がっていたが、最近、北西側の開発が進み、2003年、石川県庁舎もこちら側に移転した。金沢駅の地下道脇に、小さな日本庭園が造られている。これは金沢の街の雰囲気にいかにもふさわしい。

 14日には、城下まち金沢周遊バスの1日フリー乗車券を買って、浅野川の縁を散策した。この川は犀川と並ぶ金沢の大きな川の一つで、後者が男川と呼ばれるのに対して、こちらは女川と呼ばれている。私は3~4歳の頃、写真にある天神橋の近くの町に住んでいた。

 周遊バスを再度利用して、片町まで行き、犀川大橋を渡ってから、川岸の道へ降りてみる。桜橋と、遠方に白山へとつながる山系が見える。

 この他、金沢蓄音機館や天徳院、尾山神社、金沢の中心街、香林坊北側の裏通りを撮った写真もあり、「懐かしい郷里の街を、もっと方々歩きたかったが、今回の金沢旅行の写真はこれで終わりである」と結んでいます。

2. ウォーキング・コースの風景

 8月19日から9月12日まで、12回にわたって掲載された夏のウォーキング・コース風景は、私が昔見て、いまは変わっている景色が所々にあり、興味深く拝見しました。貴宅から往復数キロのコースだと思いますが、夏の空遠くに和泉山脈が見える川沿いの道、木の茂る公園、子ども達が遊んでいる広場、竹林、今も残る田圃、普通の町中の道など、変化に富んだ道を、季節により変わる美しさを楽しみながら逍遥され、健康維持に努められるようすが目に浮かびます。

3. About Hobbies, from and to chiamai(9月9日)

 「chiamai さんから:こんにちは、ようやく一枚の写真をお見せします。あまりよい出来ではありませんが、私が雨とストレスで眠れない様子がお分かりになるでしょう。
 chiamai さんへ:こんにちは、抽象絵画のような雰囲気の芸術的な写真ですね。長い露出をかけて撮ったのですか?
 chiamai さんから:親切なお言葉ありがとう。私のカメラで、長い露出ですが、自動設定で撮りました。「普通」の写真も何枚か撮っていますが、このほうが半睡状態で、私を起こした雨に腹を立てている様子がよく表現されています。
 chiamai さんへ:分かりました。きょう、御地のとても早い時間にリツイートされたのに気付きました。こちらも、朝から久し振りの雨です。

 彼女の写真を開くと、古風な橋を隔てて城のような建物を背景にした真夜中の静かな雨景色(9月8日)がぼかして表現されています。距離と時差を超越した、筆者との簡単な会話のやり取りと、彼女の心象を巧みに表現したこの写真を見ると、不思議な世界に誘われた気がします。

水都の一景 (A Landscape of the City of Water)


 表記題名の水彩画を先日描き上げた。来る11月15日から18日まで堺市役所本館エントランスホールで開催される美交会展に、私が出品する予定の2点のうちの一つである。

 「水都(水の都)」とは、大阪の一つの愛称である。江戸時代、各地の大名がここに蔵屋敷を作り、在来の川に加えて多くの水路を作って年貢米を運んだため、そのように呼ばれるようになった。

The other day, I have finished drawing the watercolor of the title as shown above. It is one of the two works I am going to present at Bikōkai Exhibition, which is to be held at the main building of Sakai City Hall from the 15th to 18th of November.

"The City of Water" became one of the affectionate names of Osaka in Edo Period, because a number of rivers and canals crossed there. Canals were made in that period by daimyo (powerful territorial lords) of different regions of Japan to carry annual rice tax from and to their kurayashiki (house for storage and living) by boats.

[Mary Ellen Goree] Why does the word "dyslexic" have to be so difficult to spell?

The Japanese Ministry of Education and Science is planning to add some Chinese characters to "the regularly used Chinese Characters" to be taught at primary and secondary schools. The list of characters to be added includes a very difficult one "鬱," meaning "mental depression." I'll never write it by hand.

[Mary Ellen Goree] Hmmm, I wonder if any Japanese students will become depressed by their inability to write "鬱." ;-)

[To J. Tanaka] 私は小学生のとき大連で終戦を迎えました。日本への引揚げが始まる数カ月前、中国人による大連市当局が日本人家屋の約半分を中国人向けに明け渡すことを命じたので、中国東北部奥地から引き揚げに備えて大連まで来ていた人達と近所の家族を含め、わが家に数所帯が同居しました。その中の、近所から入って貰った A 家には小学生姉妹がいて、不便な生活環境にも関わらず、「故郷を離るる歌」を朗らかによく歌っていました。姉妹の一人が学校で習ったばかりだったからでしょうが、間もなく故郷・大連を離れることになるという思いも込められていたかも知れません。
[Shortened English version of the above] I like "The song of leaving native land," because I often listened to it sung by daughters of one of families, with whom I lived together in Dalian for a few months after the end of the World War II. It was just before our leaving the land.

[From J. Tanaka] 少女の合唱団が朗らかにうたっているこの悲しい筈の別れの歌には不思議な魅力を感じました。ちなみに私の故郷はその気になれば何時でも帰れるところですが、堺市です。 鳳神社へも歩いて行けます。でも今この歌をかわいらしくも上手な少女の合唱で聞くと本当に不思議な感動を覚えました。

稲木 (Inagi: Hanger for Rice Plants)


 従来、田園では秋になると、イネを刈り取ったあと、束ねて、木材や竹で作った稲木(いなぎ、いなき、いのき)[稲掛け(いねかけ、いなかけ)、稲機(いなばた)、稲架(はさ、はざ、はせ、はぜ、はで)などとも呼ばれる]に掛けて天日で乾燥させる光景が見られたものである。しかし、最近は農作業の機械化が進んで、このような風物があまり見られなくなった。写真はわが家の近くの小さな田で見た、稲木で稲を干してある様子(2010年10月13日撮影)。

After reaping, farmers used to hang rice plants on inagi (also called inekake, inabata or hasa), made of woods or bamboos, for drying them in the sun. Because of progress in the mechanization of farming, we rarely see the scenery of rice plants hung on inagi these days.

歌声喫茶 in さかい (Utagoe Coffeehouse in Sakai)


 昨日の午後、近くの西文化会館・セミナールームで開催された「歌声喫茶 in さかい」に参加した。出演者(一ノ瀬陽子、宮本由美、喜多陵介)の歌と伴奏に合わせて参加者一同がレンタル歌本 [1] の歌詞を見ながら歌うのである。参加者総数は約70名で、そのうち男性は10名ほどだった。10分間の休憩を入れて2時間、出演者が選んだ歌の他、参加者のうちの希望者が始めに紙に書いて提出したリクェスト曲を含めて、多くの歌を歌った。

 リクェストの数は時間内にとても消化出来ないほどあり、私の提出したリクェスト用紙は読み上げられなかった。しかし、同じ曲「浜辺の歌」のリクェストは何人かの女性たちからあったということで、採用された。私は最近、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。6割ほどは知らない歌だったが、楽しい時間を過ごした。

Yesterday afternoon, I joined "Utagoe Coffeehouse in Sakai" held at the seminar room of Nishi Culture Hall, Sakai. It was the event in which participants sang songs following the singing and accompaniments of performers (Yoko Ichinose, Yumi Miyamoto and Ryosuke Kita), just like at Utagoe coffeehouses, which had been popular in Japan in ca. 1955–1975. They provided a pair of rental books [1] for us to find lyrics. The total number of participants was about 70, among which only about 10 were men. We sang many songs for 2 hours with a 10-minute break.

Some of the songs were chosen by the performers; and the rest was selected from the requests submitted at the beginning of the event. There were so many requests, so that not all of them could be sung. They did not read my wish sheet. However, the same song, "Hamabe no uta (Song of Beach)" was adopted because it was also requested by some number of women. The reason of my request was that I recently learned the third piece of the lyrics of this song. I did not know about 60% of the songs we sang, but had a joyous time.

大連の旧小学校同窓会 (The Reunion of a Former Primary School in Dalian)


 日本人の引き揚げ時期が近づいたため1941年末(私が5年生のとき)に廃校になった大連嶺前小学校の、日本での同窓会(嶺前会)総会が2年毎に開催されて、今年第16回を迎え、さる11日に東京のホテル・グランドパレス(1枚目の写真)で開催された。参加者総数は210余名で、われわれの同期生は11名だった。現会長(2枚目の写真)は、もう少し若い卒業生に席を譲ることになったが、全員の高齢化(最も若い会員もすでに70歳を超えている)に伴い、4年後に開催される第18回総会で打ち切りとなる予定である。

Near the end of 1941 (when I was a fifth-year pupil), Dalian Reizen Primary School was closed to prepare for the start of Japanese people's returning to the homeland, and graduates of the school have had a reunion (general meeting of Reizen Association) every two years in Japan. The 16th reunion was held last Monday at Hotel Grand Palace (the upper photo) in Tokyo. The total number of participants was about 210, and there were eleven classmates among them. The current chairman of the association (the lower photo) gives the role to another graduate younger than the former, but the reunion is planned to be discontinued after having the 18th meeting in 2014 because of the aging of all the members (the youngest ones are already over seventy years old).

バス旅行「秋のかやぶき音楽堂コンサート」4 (Bus Trip, "Autumn Concert at Straw Thatched Music Hall" 4)


 写真はかやぶき音楽堂の天井(上)と舞台(下)。天井に見えている太い梁の上の壁際には、2階と3階の客席がある。1階客席は、床に敷かれた座布団の上に座るようになっており、長時間姿勢を保つのがやや苦痛だった。

 コンサートの演奏者ザイラーピアノデュオ(エルンスト・ザイラー、カズコ・マサダ・ザイラー)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。この日の演奏曲目は、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 Op. 85」より「No. 1 誕生日の行進曲」他8曲、ヨハネス・ブラームス「シューマンの主題による変奏曲 Op. 23」、同「愛の歌(18曲のワルツ)Op. 52」、同「ハンガリー舞曲」から Nos. 11〜16。

 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。夫妻からの説明書には、その名が「プリオフィルム」とあったが、調べてみると、ベンケイソウ科リュウキュウベンケイ属のセイロンベンケイ [Kalanchoe pinnata (Lam.) Pers.]、別名トウロウソウ(灯籠草)である。学名のシノニムに Bryophyllum pinnatum (Lam.) Oken または Bryophyllum calycinum とある。「プリオフィルム」は、Bryophyllum がなまったものであろう。

The upper photo shows the ceiling of the straw thatched concert hall; and the lower, the stage of the hall. Near the walls above the thick beam seen in the latter photo, there are seats of the second and third floors. In the auditorium of the first floor, each listener sits on a zabuton. It was somewhat painful to keep my position on a zabuton for a long time.

The performers of the concert, Seiler piano duo (Ernst Seiler and Seiler Masada Kazuko), are actively working as an ensemble duo for four hands at different locations not only in Japan but also around the world. They are also actively searching the music for a piano duo that was unpublished or abandoned. The numbers of the concert were as follows: Robert Schumann, No. 1 (Birthday March) and other 8 numbers from 12 pieces for piano 4-hands (For Big and Small Children), Op. 85; Johannes Brahms, Variations on a Theme by Robert Schumann, Op. 23; 18 Love Song Waltzes, Op. 52; Nos. 11–16 from Hungarian Dances.

On the way back, the seedlings of Kalanchoe pinnata, the plant Johann Wolfgang von Goethe loved, were distributed as souvenirs from Seiler and his wife.

 兵庫陶芸美術館での見学後、篠山市の「お菓子の里丹波」の本館で昼食。ここには旧・神戸市警垂水署を移築改装したミオール館その他の施設もあるが、雨が降り出したので、本館から見える庭園の一部の写真を撮ることが出来ただけだった。

 2枚目の写真の手前に写っている「つくばい(蹲踞)」には、「吾唯足知」(われ、ただ足るを知る)の4字が、中央の口を共有した形で刻まれている。これは京都・龍安寺のつくばいにある文字と同じである。

After seeing the exhibition at the Museum of Ceramic Art, Hyogo, we had lunch at the main building of "Okashi-no-sato Tamba (Tamba Sweets Village)"in Sasayama. "Okashi-no-sato Tamba" is a tourist attraction and has Mior House (former Kobe-Tarumi Police Station reconstructed and renovated) and other facilities. However, it became raining, and I was able to take photos of part of the garden seen from the main building.

At the bottom of the second photo, we see a stone basin with four Chinese characters. Each of these characters shares the central bowl representing 口 as its part. The four characters together (吾唯足知) make a poem to mean "what one has is all one needs," which is the basic anti-materialistic teachings of Buddhism [1]. We also see the same poem on the basin of Ryoan-ji Temple in Kyoto.

About Physics

"Physicists convert information into energy," Technology Review arXiv blog (september 30, 2010).—"Build a tiny staircase and place a small polystyrene bead on the bottom step (a staircase is fairly straightforward to construct using electric fields). [. . .] Keep a close eye on the bead using a video camera and every time you see it go up a step, change the electric field so that it cannot drop back down again. This is like placing a barrier behind the bead. As you repeat this process, the bead will move up the staircase, driven by Brownian motion."

The changing of electric field mentioned above supply energy to the system from the outside, so that I wondered if this could be an "information heat engine." However, the authors, S. Toyabe et al., of the related paper (arXiv:1009.5287v2) write, "Under real-time feedback control, the particle climbs up a spiral-stairs-like potential exerted by an electric field and obtains free energy larger than the amount of work performed on it."

Quotations

「経験」とは、自身の内的な成熟のために「心の平衡を失うこと」を厭わずに「身を開いて」生きることなのである。そしてまた読書という営みも、「開かれた」姿勢でなされなければ、「経験」にはなり得ないものなのだ。——泉谷閑示「読書する怠け者、読書しない怠け者」図書 No. 740, p. 11 (2010年10月号); "Experience" comes from living for one's own inner maturity by "opening oneself" without hesitating "to lose mental balance." The deed of reading also requires an "open" attitude to become "experience." - Kanji Izumiya, "The lazy person who reads and the lazy person who does not," Tosho No. 740, p. 11 (2010).
