Quantum mechanics has spawned numerous interpretations attempting to explain the same mathematical formalism. Select three competing interpretations (such as Copenhagen interpretation, many-worlds interpretation, pilot-wave theory, objective collapse theories, or quantum Bayesianism) and provide a detailed analysis of each. For each interpretation, explain its core principles, how it addresses the measurement problem, and its philosophical implications regarding determinism, locality, and realism. Compare the strengths and weaknesses of each approach based on both theoretical considerations and experimental viability. Conclude with your assessment of which interpretation (if any) provides the most coherent account of quantum phenomena.
