Fresnel Reports on Birefringence Experiment
In a note presented to the Academy of Sciences, Augustin-Jean Fresnel discusses a direct refraction experiment that verifies David Brewster's hypothesis regarding photoelasticity. This phenomenon, now recognized as stress-induced birefringence, showcases how materials change optical properties under stress. Fresnel's findings contribute to the understanding of light behavior in different media, marking a significant advancement in optics.

Augustin Fresnel presented his groundbreaking memoir on light diffraction to the French Academy of Sciences. This work meticulously detailed the behavior of light as it interacts with obstacles, particularly the phenomenon of diffraction, wherein light seemingly spreads into shadows and around edges. Fresnel's research countered long-standing criticisms of the wave theory of light, providing compelling evidence that established the wave nature of light more clearly than ever before. His insights not only advanced the understanding of optical physics but also laid the groundwork for future innovations in this field.

The Russian Academy of Sciences was founded in St. Petersburg by Peter the Great through a Senate decree. Initially named the St. Petersburg Academy of Sciences, its establishment aimed to promote scientific research and education in Russia, reflecting Peter's vision for modernizing the nation and boosting its intellectual capabilities. The academy attracted many prominent scientists and became a leading institution in various fields until its renaming in 1917 after the Russian Revolution.
