I saw in a dream a table where all the elements fell into place as required. Awakening, I immediately wrote it down on a piece of paper
Russian chemist and inventor. He formulated the Periodic Law, created a farsighted version of the periodic table of elements, and used it to correct the properties of some already discovered elements and also to predict the properties of eight elements yet to be discovered.

Be kind, for everyone you meet is fighting a harder battle
No one can make you feel inferior without your consent
