American-born British theoretical physicist David Bohm made many significant contributions to physics. But he's most famous for challenging convention and interpreting quantum mechanics in terms of nonlocal or hidden variables. Several eminent contemporaries accused him of defending outdated ideals based in deterministic physics, rather than embracing his contemporaries' non-deterministic views.
In a study published in The European Physical Journal H, Andrea Oldofredi, of the University of Lisbon, Portugal, revisits Bohm's private correspondences and academic works to reconstruct the evolution of his philosophical trajectory. The analysis indicates that bias against Bohm was mostly not based on scientific grounds, and instead underlines the originality of his ontological reflections.
Bohm presented his famous pilot wave theory in 1952. In addition to a wave function, that he considered a new kind of physical field, each particle has a definite location, with position changes governed by the quantum potential. These changes occur in a way that depends on what all other particles are doing. Wolfgang Pauli called it a cheap solution; and Leon Rosenfeld called it a positively harmful "new obscurantism."
