“Locality” is a fraught word, even within the restricted context of Bell’s theorem. As one of us has argued elsewhere, that is partly because Bell himself used the word with different meanings at different stages in his career. The original, weaker, meaning for locality was in his 1964 theorem: that the choice of setting by one party could never affect the outcome of a measurement performed by a distant second party. The epitome of a quantum theory violating this weak notion of locality (and hence exhibiting a strong form of nonlocality) is Bohmian mechanics. Recently, a new approach to quantum mechanics, inspired by Bohmian mechanics, has been proposed: Many Interacting Worlds. While it is conceptually clear how the interaction between worlds can enable this strong nonlocality, technical problems in the theory have thus far prevented a proof by simulation. Ghadimi, Hall and Wiseman report significant progress in tackling one of the most basic difficulties that needs to be overcome: correctly modelling wavefunctions with nodes.

George Musser: "Usually when physicists talk about nonlocality, they mean spatial nonlocality—influences leaping across the void. But if Einstein taught us nothing else, it is that space and time are woven together. So if there is spatial nonlocality, there should also be temporal nonlocality—influences leaping across spans of time, explains theoretical physicist Emily Adlam, who just received her Ph.D. from the University of Cambridge."

About 350 registered attendees made the EmQM17 London symposium a great success. A strong case was made for the possibility of ontological quantum mechanics on the occasion of the David Bohm Centennial celebration at Senate House of the University of London, adjacent to Birkbeck College, Prof. Bohm's final academic home.

The Cozzarelli Prize of the US National Academy of Science has been awarded to a project of the Institute of Quantum Studies, which is led by Yakir Aharonov and Jeff Tollaksen, at Chapham University, California. The Cozzarelli Prize is awarded annually for published PNAS papers “of outstanding scientific excellence and originality.” The winners were recognized during the National Academy of Sciences Annual Meeting Awards Ceremony on April 30, 2017, in Washington, D.C. Chapman acknowledges support (in part) for this project by the Fetzer Franklin Fund of the John E. Fetzer Memorial Trust. The photo shows two members of the team who received the prestigious award at the ceremony, Jeff Tollaksen (right) and Sandu Popescu (left).

“Is quantum physics a stepping stone to a deeper understanding of reality?” asks Michael Brooks in his report on the Vienna Symposium, which was published on November 14, 2015, in New Scientist magazine. The Vienna Quantum Symposium was sponsored by the Fetzer Franklin Fund (FFF) and its major purpose was to explore whether there could – in fact – exist “pre-existing connections between all quantum particles”: Is the world local or nonlocal? A radically holistic conception of quantum reality was first envisioned in de Broglie-Bohm theory in the 1950s, the best-known alternative formulation of quantum mechanics.

The report by Michael Brooks features statements by EmQM15 presenters also, including by Aephraim Steinberg (Univ. Toronto, Canada), Lev Vaidman (Tel Aviv Univ., Israel), Markus Arndt (Univ. Vienna, Austria), Nobel Laureate Gerard ‘t Hooft (Utrecht Univ., Netherlands), Howard Wiseman (Griffith Univ., Australia), and Jan Walleczek (FFF and Phenoscience Laboratories, Berlin, Germany).

How to address the current reproducibility crisis in science? The acceptance and impact of breakthrough findings depends on the ability to reproduce these findings by independent investigators. To explore the challenge of reproducibility from a meta-scientific perspective, the Fetzer Franklin Fund (FFF) co-sponsored a conference on scientific integrity and “Best Practices in Science” (BPS) at Stanford University’s Center for Advanced Study in the Behavioral Sciences. The conference was held on June 18-19, 2015. Lead Organizer Jon Krosnick, a social psychologist at Stanford University, is a member also of the FFF multi-center team exploring the so-called “Decline Effect”, and the role of the experimenter agent in science. The other four members of this inter-laboratory research initiative include Jonathan Schooler (UC Santa Barbara), Leif Nelson (UC Berkeley), Brian Nosek (Center for Open Science, Charlottesville), and Jan Walleczek (FFF and Phenoscience Laboratories, Berlin).
