Simple Summary: I discuss whether a signature of the quantum origin of large scale structures observed in our Universe can be found.Abstract: According to the theory of cosmic inflation, the large scale structures observed in our Universe (galaxies, clusters of galaxies, Cosmic Background Microwave -CMB -anisotropy . . . ) are of quantum mechanical origin. They are nothing but vacuum fluctuations, stretched to cosmological scales by the cosmic expansion and amplified by gravitational instability. At the end of inflation, these perturbations are placed in a two-mode squeezed state with the strongest squeezing ever produced in Nature (much larger than anything that can be made in the laboratory on Earth). This article studies whether astrophysical observations could unambiguously reveal this quantum origin by borrowing ideas from quantum information theory. It is argued that some of the tools needed to carry out this task have been discussed long ago by J. Bell in a, so far, largely unrecognized contribution. A detailed study of his paper and of the criticisms that have been put forward against his work is presented. Although J. Bell could not have realized it when he wrote his letter since the quantum state of cosmological perturbations was not yet fully characterized at that time, it is also shown that Cosmology and cosmic inflation represent the most interesting frameworks to apply the concepts he investigated. This confirms that cosmic inflation is not only a successful paradigm to understand the early Universe. It is also the only situation in Physics where one crucially needs General Relativity and Quantum Mechanics to derive the predictions of a theory and, where, at the same time, we have high-accuracy data to test these predictions, making inflation a playground of utmost importance to discuss foundational issues in Quantum Mechanics.

Opening the Gender Box: Legibility Dilemmas and Gender Data Collection on U.S. State Government Forms

US states collect sex and gender data on official government forms to understand, identify, classify, and surveil populations. These forms’ gender boxes—sets of questions about sex, gender, and gender identity paired with a wide variety of answer options—can mean the difference between legibility and erasure or between surveillance and privacy. They also create classic disclosure and legibility dilemmas that disproportionately burden transgender, nonbinary, gender-nonconforming, and intersex individuals. And yet, the socio-legal forces determining the design of these gender boxes have been insufficiently studied. Documents obtained through public records requests and interviews with civil servants responsible for form design demonstrate that gender box design stems from the competing yet mostly inertial pressures that define the socio-legal contexts of street-level bureaucracy. In other words, gender boxes are products of the institutional, technological, political, and social contexts in which they are designed. Specifically, gender boxes look the way they do because they are subject to the effects of bureaucratic processes, social networks, expertise, intergovernmental dependence, norms, path dependencies, and technologies, with implications for research and advocacy.
