The periodic table has been giving a great impact not only on the development of human technologies but also on the advances in natural science, such as physics, biology, geology, astronomy, and so on.2019 is the 150th anniversary on the discovery of the periodicity of chemical elements by Dimitry Mendeleev. Moreover, International Union of Pure and Applied Chemistry (IUPAC) has been giving a great contribution to establish various regulations regarding all chemistry issues, such as atonomic weights and isotopic abundances of elements, names of elements, and so on. IUPAC also celebrates its 100th anniversary in the same year.The United Nations and UNESCO proclaimed2019 as the "International Year of the Periodic Table of Chemical Elements (IYPT2019)".
Let's cerebrate IYPT2019 by giving our appreciation to the pereiodic table which has given various impacts to our society.We hope many IYPT2019 activities will be planned and held in Japan. Please share your IYPT2019 activities in Japan with us.
