Question

In 1794, the German physicist Ernst Chladni published a provocative treatise arguing that stony and metallic masses found on Earth's surface originated from cosmic space rather than terrestrial volcanic eruptions or atmospheric aggregations, as prevailing eighteenth-century consensus maintained. Chladni arrived at this conclusion not through direct astronomical observation, but by analyzing historical accounts of witnessed falls and evaluating the chemical composition of iron specimens, which contained nickel proportions absent in terrestrial iron ores. Although Chladni’s hypothesis was initially met with widespread skepticism by contemporary scientific institutions—who dismissed reports of falling stones as folk superstition unbefitting the Rationalist Era—the discovery of the L'Aigle meteorite shower in 1803 forced the French Academy of Sciences to reexamine his claims. Biologist Jean-Baptiste Biot was dispatched to L'Aigle to conduct a systematic field investigation, gathering eye-witness testimonies from hundreds of villagers and mapping the distribution ellipse of the fallen debris. Biot’s meticulous methodology demonstrated a high degree of spatial clustering inconsistent with atmospheric phenomena and corroborated Chladni's foundational premise. Consequently, Chladni’s work, paired with Biot’s empirical validation, established meteoritics as a legitimate branch of physical science, fundamentally altering scientific understanding of interplanetary matter.
