What a pleasant surprise!

Mendeleev

I don’t normally notice the special images on Google’s search page but was pleasantly surprised this morning to see this one.

It’s great to see some people are celebrating  Dmitri Mendeleev’s 182nd birthday. He was born February 8, 1834 , in the village of Verkhnie Aremzyani, near Tobolsk in Siberia.

Mendeleev is considered the “father” of the Periodic Table. I remember as a school student being fascinated by the periodic table and the early versions of it as the researchers of the time attempted to make sense of chemistry. That fascination remained with me as my study of chemistry became more advanced Today, the table is firmly based in quantum physics and can be derived directly from quantum considerations. Yet, in  those early days, no-one had that theoretical insight and derived the table from the chemical and physical properties of the then-known elements. The fact this enabled them to predict the existence of other elements, and the fact this lead to successful searches for them, has always inspired me.

So, Dmitri Mendeleev is one of the giants whose shoulders today’s scientists stand on. Only natural then that this commemorative ruble marking the 150th anniversary of his birth is a prized souvenir I picked in up Moscow 30 years ago.
