About the image of the website icon and background

The green background color of the website icon was decided by the image of growing in the color of the plant. The letter "Edutt" is an acronym for education and me, and in the image, this represents an exponential increase. The image of the background is nandina domestica. I imagine that the plant is absorbing all the electromagnetic waves (below infrared rays + visible rays + above ultraviolet rays) and finally make the fruits. The plant has long been regarded as an auspicious tree because of the sound of "Turning over difficulties" in Japanese. My email address is also nandina domestica.

About RSS distribution

RSS (Rich Site Summary) is an XML-based data format for distributing website summaries and article headings. You can read it using an RSS reader. For your reference, I subscribe to RSS on about 30 sites. The main thing about the English sites among them is 1. WIRED: https://www.wired.com/feed/rss 2. Ars technica(Science): http://feeds.arstechnica.com/arstechnica/science. For iPhone, iPad, and Mac users, I made the shortcuts(app), so please check these.
