リュウキュウアサガオ (Oceanblue Morning Glory)


 いままで、写真の花はセイヨウアサガオと思っていたが、リュウキュウアサガオ(琉球朝顔、ヒルガオ科)らしい。リュウキュウアサガオは、「オーシャンブルー」「宿根アサガオ」など多くの異なる名称で販売されているという。2010年7月28日、堺市・中の池公園で撮影。

Oceanblue morning glory, blue morning glory, koali awa or blue dawn flower; botanical name, Ipomoea indica (a genus); family, Convolvulaceae. The photo was taken at Nakanoike Park, Sakai, on July 28, 2010.

About Arts

Watched an NHK TV program telling the inside story of the Japanese anime film "The Borrower Arrietty" last evening. The efforts of the new director Hiromasa Yonebayashi at Studio Ghibli were well depicted as well as Ghibli founder Hayao Miyazaki's patient observation of him.

About Mathematics

[Retweet of newscientist's words with an addition] "P ≠ NP: Has the biggest question in computer science been solved?" (http://bit.ly/bgtc6r) (via @physicsdavid) - Good explanation.

About Physics

"How to perform the perfect stone skim," Telegraph (http://bit.ly/cSwj97) - I read about a similar study before in the journal Nature: "Secrets of successful stone-skipping" (http://bit.ly/djkj9w).
