Long before there was a periodic table of the elements, there was no need for a table — just four chairs. From ancient through medieval into early modern times, natural philosophers could count the ...

Since the invention of the periodic table 150 years ago this month, scientists have worked to fill in the rows of elements and make sense of their properties. But researchers have also pursued a ...
