Over the past few months, I've been trying to memorize the periodic table of the elements.
It's not for any real reason, I just thought I'd pickup a personal challenge. And it's certainly not been easy.
I've been working through it learning one lien at a time, and I've gotten stuck.
Now I'm good through Argon (18), that's three lines. But to complete the next line I have to double the elements that I can recite.
So, I'm working on it, but we'll see.
I do have an urge to learn the etymologies of the element names now though.
