I try to contribute to things getting better, with sourced information, OC and polite rational skepticism.
Disagreeing with a point ≠ supporting the opposite side, I support rationality.
Let’s discuss to make things better sustainably.
Always happy to question our beliefs.

  • The NIH article seems to support your point.

    In conclusion, our results from a large cross-cultural sample demonstrate that women’s preferences for male facial masculinity are positively associated with economic development and individual differences in sexual openness, which complements findings from cross-cultural studies of men’s preferences for women’s facial femininity67. However, we found no evidence that indices of male-male competition (i.e. homicide rates and income inequality) were predictors of women’s facial masculinity preferences. Future cross-cultural research quantifying women’s mate preferences for facial masculinity that include individual differences data among participants from small-scale to more urban settings regarding their fear of violence would be valuable30. For the present, our findings suggest that in countries with more favourable social, ecological and economic conditions, wherein any costs of selecting less paternally investing masculine partners may be reduced, women’s preferences for facial masculinity are higher.




















  • The abstract of the scientific article

    In the relentless pursuit of quantum computational advantage, we present a significant advancement with the development of Zuchongzhi 3.0. This superconducting quantum computer prototype, comprising 105 qubits, achieves high operational fidelities, with single-qubit gates, two-qubit gates, and readout fidelity at 99.90%, 99.62%, and 99.13%, respectively. Our experiments with an 83-qubit, 32-cycle random circuit sampling on the Zuchongzhi 3.0 highlight its superior performance, achieving 1×106 samples in just a few hundred seconds. This task is estimated to be infeasible on the most powerful classical supercomputers, Frontier, which would require approximately 5.9×109  yr to replicate the task. This leap in processing power places the classical simulation cost 6 orders of magnitude beyond Google’s SYC-67 and SYC-70 experiments [Morvan et al., Nature 634, 328 (2024)], firmly establishing a new benchmark in quantum computational advantage. Our work not only advances the frontiers of quantum computing but also lays the groundwork for a new era where quantum processors play an essential role in tackling sophisticated real-world challenges. https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.134.090601

    Random circuit sampling is a problem designed to showcase quantum computing strength. Random circuit sampling is the simulation of the outcome of many randomly generated quantum circuits. So, having a computer based on quantum phenomenon, such as superposition and entanglement, is obviously a big help, as opposed to having to imperfectly simulate this on a classical computer. So much that classical super computer cannot simulate this problem in a reasonable human time anymore. They call this “quantum superiority”.
    It’s like giving a math problem to a math professor and a philosophy professor, and then demonstrating how much better the math professor was at solving this problem.
    But it’s a good benchmark to compare quantum computers between them.

    Overall, it’s still useless to the average server or gamer.
