Task 2 - Max Planck and Albert Einstein Before the work of Max Planck and Albert Einstein, classical theory was the predominant scientific thought. However, it eventually became apparent that classical theory was unable to explain the occurrence of some phenomena observed in the experimental data, particularly blackbody radiation and the photoelectric effect. The works of both Planck and Einstein led to the development of quantum theory and contributed greatly to the understanding of society. Since Planck and Einstein were both affected by the two world wars, their work also played a role in politics. Einstein was an activist for world peace and believed that scientific research should be distanced from social and political forces and instead focused 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 the Second World War Planck remained in Germany conducting research aimed at the war effort and faithful to the aims of the Nazi doctrine, while Einstein left Germany for the United States of America. Classical Theory and Blackbody Radiation The classical theory of thermal radiation states that thermal radiation originates from the acceleration of charged particles near the surface of the object, and these charges emit radiation. It is also stated that as the temperature of the object increases, the acceleration of the oscillation (frequency) of the charges increases and the intensity of radiation of shorter wavelength (higher frequency) increases. However, as Figure 1 illustrates, there was a discrepancy between the classical theoretical prediction and the experimental result… in the middle of the paper… the greater the total radiated energy (for a given temperature). Einstein also explained that the behavior of waves and particles 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 eventually succeeded in confirming Planck's proposals. Without Einstein, the idea of ​​quantization could have easily been dismissed. Instead, Einstein extended quantum theory.
