Wenn man Kinder schon darauf trainiert, Kanonenfutter zu werden, wenn sie gross sind:
Mir tun die Bilder über russische Kinder, die für den Krieg trainiert werden, weh.
Gelernt: Putin muss sich rechtfertigen, dass er nach 25 Jahren immer noch im Amt ist, und die Rechtfertigung, die seinem Volk am ehesten einleuchtet, ist: Russland befindet sich im Krieg gegen einen faschistischen Westen. 🤷 😔

Muss sich die Schweiz vor Russland fürchten – Patriotismus und Aufrüstung (Teil 1) - Reporter - Play SRF
Für das offizielle Russland ist die Schweiz nicht mehr neutral. Sie gilt als Teil des «kollektiven Westens», dem Russland feindlich gegenübersteht. In Russland haben wir ein Land im Kriegsmodus getroffen. Die Bevölkerung, insbesondere die Jugend, wird auf militärisch-patriotischen Kurs gebracht. «Reporter» ist unterwegs in Russland. Und trifft ein Land im Kriegsmodus, in dem seit Jahren eine Militarisierung der Gesellschaft, insbesondere der Jugend, betrieben wird. Begriffe wie Dienst a…

Temporal Entanglement and Witnesses of Non-Classicality
The universality of quantum theory has been questioned ever since it was proposed. Key to this long-unsolved question is to test whether a given physical system has non-classical features. Here we connect recently proposed witnesses of non-classicality, based on information-theoretic ideas, with the theory of temporal entanglement. We provide a protocol to witness the non-classicality of a system by probing it with a qubit: we show that, assuming a general conservation law, violating temporal B…

An Irishman in Ireland has posted a picture of his Irish flag flying outside his house (in response to some sports thing, apparently?)
The comments are exclusively full of Irish people spouting vitriol about the United States

The Anglosphere mind has been fully reverse-colonised by its biggest boi. They define themselves in opposition to it; without it, they would have no identity at all. Very sad state of affairs.

Gravothermal expansion of dwarf spheroidal galaxies heated by dark subhaloes
We use analytical and $N$-body methods to study the evolution of dwarf spheroidal galaxies (dSphs) embedded in dark matter (DM) haloes that host a sizeable subhalo population. Dark subhaloes generate a fluctuating gravitational field that injects energy into stellar orbits, driving a gradual expansion of dSphs. Despite the overall expansion, the stellar density profile preserves its initial shape, suggesting that the evolution proceeds in a self-similar manner. Meanwhile, the velocity dispersio…

Universal Quantum Computational Spectroscopy on a Quantum Chip
Spectroscopy underpins modern scientific discovery across diverse disciplines. While experimental spectroscopy probes material properties through scattering or radiation measurements, computational spectroscopy combines theoretical models with experimental data to predict spectral properties, essential for advancements in physics, chemistry, and materials science. However, quantum systems present unique challenges for computational spectroscopy due to their inherent complexity, and current quan…
