Session 01 - Planck, 1900

In the late 19th and early 20th centuries, discrepancies were observed between experimental results and theoretical predictions based on classical physics. Among these discrepancies was the problem of black-body radiation. The total radiative power of a black body was described using thermodynamic considerations, but the frequency distribution of this radiation was inconsistent with theoretical predictions. In 1900, Max Planck proposed a relationship for the frequency distribution of black-body radiation by introducing the hypothesis of quantized energy, which showed significant agreement with experimental data. This achievement is considered the foundation for the development of quantum mechanics. In this session, the historical context and content of Planck’s paper will be examined and analyzed.
