My new glasses arrived this week. Let’s hope my spelling improves.
This week’s lesson was The Periodic Table. And with that sentence, I just lost most of my readers. Those of you still with me – imagine the vague underlying sense of discontent that haunted the chemists all through the 1860’s as they kept discovering elements, 63 in all, but without hope of reaching a greater understanding.
I used to work for a scientist who often said “Simple is best, unless it’s wrong.” Dimitri Mendeleev created the first Periodic Table simply and correctly by arranging the elements in ascending order of atomic mass. In doing so, he unlocked a powerful secret about those 63 and all that came after. The elements had a pattern and it was a pattern of eights.
Just like my new glasses, Mendeleev’s list made everything in the world a little clearer. The elements suddenly looked like neighbors, grouped together by common interests and behavior. Holes in the list were simply houses under construction waiting for germanium, gallium, and scandium to arrive.
This begged a much larger question: What other neighborhoods were out there and just how large was this city?
