Wave-particle duality presents a compelling research project due to its inherent controversies, particularly between the photoelectric effect and Young's double slit experiment. The discussion emphasizes the importance of exploring how electrons create interference patterns, even when emitted individually. Suggestions include investigating higher-dimensional space vibrations as a potential explanation for duality, although this may exceed A-Level scope. Alternative project ideas, such as the solar neutrino controversy, were also proposed, but sticking to familiar topics is recommended. A timeline approach, tracing historical perspectives from Newton to Einstein, could effectively illustrate the evolution of understanding in this area.
