My Meeting with David Bohm
June 29, 2023. Some scientists seek to clarify reality, others to mystify it. Physicist David Bohm seemed driven by both impulses. He is renowned for promoting a sensible (according to experts like Einstein, John Bell and philosopher Tim Maudlin) interpretation of quantum mechanics. But Bohm also a

A successful example of "adversarial collaboration"
We synthesized the vast, contradictory scholarly literature on gender bias in academic science from 2000 to 2020. . . . Claims and counterclaims regarding the presence or absence of sexism span a range of evaluation contexts. Our approach relied on a combination of meta-analysis and analytic dissection. We evaluated…
