Paulo Castro studied Physics at the Faculty of Sciences of the University of Lisbon and moved to the Humanities where he graduated in Anthropology at the University Nova de Lisboa in 1996. He holds a PhD in the philosophy of contemporary thought from the University Lusófona of Humanities and Technologies. In 2015 he joined the Philosophy of Natural Sciences Research Group, at the Centre for Philosophy of Sciences of the University of Lisbon, working on the philosophy of nonlinear Quantum Mechanics. John W. M. Bush is a Professor of Applied Mathematics at MIT. He completed his BSc and MSc in Physics at the University of Toronto and his PhD in Geophysics at Harvard University, before pursuing postdoctoral research at the University of Cambridge’s DAMTP. He joined the faculty of MIT in 1998, was tenured in 2004 and now directs the Applied Mathematics Laboratory. His research began in geophysics, but then shifted towards surface-tension-driven phenomena and their applications in biology. For the past decade, his research has been focused on hydrodynamic quantum analogs.  José Croca directed the Research Group on the Foundations of Quantum Physics at the Centre for Philosophy of Sciences of the University of Lisbon. Held a teaching position at the Department of Physics of the University of Lisbon. Did his PhD in 1985 at the University of Lisbon under the supervision of J. Andrade e Silva, one of the most direct collaborators of Louis de Broglie. Did postgraduate research at the University of Bari with Professor Franco Selleri. He is the author of innumerous scientific books, papers and talks in international conferences about nonlinear causal quantum physics. He has proposed several experiments to detect quantum waves and introduced a non-linear Schrödinger equation and its wavelet-based set of generalized uncertainty relations, from which Heisenberg’s result as a particular case. Founding member of the Centre for Philosophy ofSciences of the University of Lisbon.
