"Based upon key publications by Paul Oskar Kristeller (1938) and especially Frances A. Yates (1964), it has been widely assumed that an important “Hermetic Tradition”
emerged during the Renaissance and that Marsilio Ficino’s Latin translation of the Corpus Hermeticum (first ed. 1471) was at its origin. This article argues that these
assumptions need to be revised."

"The discovery of the 118 chemical elements known to exist as of 2023 is presented in chronological order. The elements are listed generally in the order in which each was first defined as the pure element, as the exact date of discovery of most elements cannot be accurately determined. There are plans to synthesize more elements, and it is not known how many elements are possible. Each element's name, atomic number, year of first report, name of the discoverer, and notes related to the discovery are listed."
