Thoughts on the periodic table

Eric Scerri has written the definitive history of Mendele’ev’s periodic table and how it came to be formulated.

Thus, ontology has gone the way of taxonomy, being dragooned into service of database techniques, to mean something quite the opposite of what it originally meant. I have noticed this tendency of Read More…
