International Day of Light—“Light, Innovation, Society”, 16 May 2025
Celebrating the International Day of Light, we reflect on light’s essential role in connecting scientific discovery with daily life. Guided by the 2025 theme, “Light, Innovation, Society”, we explore how light transcends boundaries—driving innovations across disciplines, enhancing human experiences, and fostering collaborative solutions to shared challenges. As both a universal symbol and a scientific tool, light continues to inspire curiosity, creativity, and meaningful connections in an ever-evolving world.
MDPI invites researchers and readers to engage with our open access journals, Special Issues, and collaborative platforms dedicated to advancing light-related research. Discover freely accessible studies spanning from foundational principles to emerging applications, participate in global discussions through interdisciplinary forums, and contribute to open science efforts that bridge ideas and communities. Together, let us harness light’s simplicity and depth to spark dialogue, empower collective progress, and illuminate pathways toward a brighter, more inclusive future.
