Louis de Broglie

About Louis de Broglie

Louis de Broglie was a pivotal figure in 20th-century physics, best known for his revolutionary hypothesis that matter exhibits wave-like properties, a concept known as wave-particle duality. This groundbreaking work, which extended the quantum theory established by Planck and Einstein, earned him the 1929 Nobel Prize in Physics. MIT's Pantheon project ranks him highly at #888 for his profound, though perhaps specialized, contribution to modern physics, placing him among the most historically influential individuals globally.

Despite his high historical importance ranking, de Broglie’s current internet attention appears relatively muted. His page recorded approximately 150K annualized Wikipedia views in 2025, resulting in an Attention Gap ratio of -2x, indicating he is significantly underattended relative to his historical influence. For contrast, a figure ranked much higher in importance, Huang Xianfan (#130), receives only 20K views, showing that for some influential figures, online visibility does not align with historical measure. While his visibility is slightly increasing year-over-year (+3.3%), his recent 2025 Momentum dropped by -8% between Q1 and Q3, suggesting a slight cooling of public interest in his work this year.
