バス旅行「秋のかやぶき音楽堂コンサート」2 (Bus Trip, "Autumn Concert at Straw Thatched Music Hall" 2)


 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.

Wrote a comment on the above blog post: I get 1+α, not 0, for αx+1 with x=1. Am I wrong?

[From republicofmath in reply to my comment] Tatsuo, thanks for your blog comment. I made your correction.

[To republicofmath] You're welcome. The corrected figure for the triangle became less like a triangle in appearance.

バス旅行「秋のかやぶき音楽堂コンサート」1 (Bus Trip, "Autumn Concert at Straw Thatched Music Hall" 1)


 昨日、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った。ここは、2005年に出来た新しい美術館で、敷地面積は 49,000 平方メートルある。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。写真は、同美術館の庭園と建物のごく一部である。

Yesterday, my wife and I joined a bus trip titled, "Autumn Concert at Straw Thatched Music Hall." The buses started at 9:00 a.m. from JR Osaka Station. We first dropped at the Museum of Ceramic Art, Hyogo, located at Sasayama, Hyogo. The museum is a new one completed in 2005 and has the site area of 49,000 square meters. There, we appreciated the exhibition, "The Beauty of Pottery Created by Molds: Kakiemon and Sanda." The photos show only part of the gardens and the buildings of the museum.

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."

「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).
