Table of Elements
Well, who knew? Dmitri Mendeleyev of Russia wrote down and set in place in 1869 what would haunt me more than 100 years later. Dmitri has a statue here in St. Petersburg. I only saw a photo op of statue with snow and I ran off to snap the picture. Upon returning to my group, I asked, so who is that statue? They pointed to the big wall on the side (previously un-noticed by me) and replied "that guy, who did the table." Sure enough, to the right was a big, giant periodic table. But before I could do anymore, our hitch-hike luck had worked and a car was ready to take us to the next work stop.
