Except, Mendeleev didn't invent it.
Just refined(?) it to a better(?) way than the other ways.
PS, I called one of my computers Mendeleev (big fan)... and this morning I was thinking about installing exherbo on it, with herbstluftwm. Have we got a complete periodic table for distros and another for window managers? ;D
[Edit, oh wait, oh. No. Mendeev died. It's Ferraris that sits in that corner now. Named after Gallileo Ferraris. Teachers didn't teach me that. I had to learn it myself, with an internet connection and a library card. School failed me. I wish the teachers had got me to memorise the periodic table. Instead, they said to ignore it, without saying to ignore it, but focussing on what felt like 99.999,999% only on hydrogen and carbon. And after they promised to teach it all, too. I'm like the guy in the picture, hands on hips, glaring, at the teachers and school system. ... Because they didn't get me to memorise the periodic table of elements.]
