John Bell

John Bell was a physicist known for his groundbreaking work on the foundations of quantum mechanics. He formulated Bell's Theorem, which demonstrates that certain predictions of quantum mechanics cannot be reconciled with classical concepts of locality and realism. Essentially, his work showed that if quantum mechanics is correct, then particles can be correlated in ways that defy our everyday understanding of how objects should interact, leading to implications for concepts like entanglement. Bell's Theorem challenges our notions of causality and has profound philosophical implications, influencing debates on the nature of reality in both physics and philosophy.
