Amedeo Avogadro

About Amedeo Avogadro

Amedeo Avogadro (1776–1856) was an Italian chemist and physicist whose foundational work forms a cornerstone of modern chemistry. His most enduring contribution is Avogadro's Law, which postulates that equal volumes of all gases, at the same temperature and pressure, have the same number of molecules. This principle, which led to the concept of the "mole"—a standard unit for measuring large quantities of very small entities—is central to stoichiometry and physical chemistry, securing his #962 rank in MIT's Historical Popularity Index.

Despite this fundamental importance, Avogadro currently experiences a significant internet attention deficit, registering an "Attention Gap" of -3x relative to his historical weight. In 2025, his Wikipedia page accrued an estimated 109K annualized views. This level of attention is dwarfed by figures of far lesser historical influence; for instance, he receives five times fewer views than Camilla, Duchess of Cornwall (#446 importance), and Helena (#354 importance), illustrating a clear disconnect between historical chemical impact and contemporary online visibility.

While interest is down 7.7% year-over-year, his recent momentum shows a slight $+8\%$ increase between Q1 and Q3 of 2025, suggesting a minor, recent uptick in curiosity surrounding his work.
