Task 2 - Max Planck and Albert EinsteinBefore the work of Max Planck and Albert Einstein, classical theory was the predominant scientific thought. However, it eventually became clear that classical theory was unable to explain the occurrence of certain phenomena observed in the experimental data, including black body radiation and the photoelectric effect. The work of Planck and Einstein led to the development of quantum theory and contributed greatly to the understanding of society. Both Planck and Einstein were affected by the two world wars, so their work also played a political role. Einstein was an activist for world peace and believed that scientific research should be distanced from social and political forces and focus instead on the pursuit of knowledge and understanding. On the other hand, Planck was very patriotic and supported the rise of the Nazi regime. He believed that the purpose of science was to support a social and political agenda. During World War II, Planck remained in Germany to conduct research oriented toward the war effort and true to the goals of Nazi doctrine, while Einstein left Germany for the United States of America. Classical theory and black body radiation The classical theory of thermal radiation states that thermal radiation arises from the acceleration of charged particles near the surface of the object and these charges emit radiation. It also states that as the temperature of the object increases, the acceleration of oscillation (frequency) of charges increases and the intensity of shorter wavelength (higher frequency) radiation increases. However, as shown in Figure 1, there was a gap between the classical theoretical prediction and the experimental result...... middle of paper ...... the larger the total energy radiated (for a given temperature). Einstein also explained that wave and particle behavior could coexist. In 1916, Robert Millikan confirmed Einstein's equation for the kinetic energy of the electron and Planck's constant. Verdict Therefore, I believe that Albert Einstein is the “father of quantum theory”. Although Max Planck was the founder of quantum theory, he doubted his own explanations. Einstein accepted Planck's hypotheses as true and was ultimately able to confirm Planck's propositions. Without Einstein, the idea of ​​quantification could have been easily dismissed. Instead, Einstein extended quantum theory.
