Tickle the hearts of science lovers ♪ I found a product called "The World's Most Beautiful Periodic Table Shijiki" (Hyakushosha) on Amazon.co.jp and bought it.

An underlay (A4 version) printed with a periodic table with photos by Theodore Gray. As the name "The Most Beautiful Periodic Table in the World" suggests, the various substances that emerge on a black background make you feel the beauty of art. It is also a nice point that the 113th element, which was discovered by a Japanese research group and officially decided as "nihonium (Nh)" in November 2016, is properly contained. On the back side, the properties of each element such as atomic weight, melting point, boiling point, and density are described.



Similarly, from Hypothesis, a stationery called "Monosashi to see history" is also available. This is a 30 cm plastic ruler with the Japanese era divisions from 1 AD to 2000. If you take a quick look at each time you use it, it will be easier to keep up with the topics of Japanese history.



The selling price on Amazon.co.jp was 540 yen for both "The most beautiful periodic table in the world" and "Monosashi to see history". Not only as an adult collection, but also as a gift for children who are interested in science and history.
