  2. Quantum computing - Wikipedia

    en.wikipedia.org/wiki/Quantum_computing

    While current quantum computers may speed up solutions to particular mathematical problems, they give no computational advantage for practical tasks. Scientists and engineers are exploring multiple technologies for quantum computing hardware and hope to develop scalable quantum architectures, but serious obstacles remain.

  3. Sun - Wikipedia

    en.wikipedia.org/wiki/Sun

    Fusing four free protons (hydrogen nuclei) into a single alpha particle (helium nucleus) releases around 0.7% of the fused mass as energy, [68] so the Sun releases energy at the mass–energy conversion rate of 4.26 billion kg/s (which requires 600 billion kg of hydrogen [69]), for 384.6 yottawatts (3.846 × 10 26 W), [5] or 9.192 × 10 10 ...

    The reactor went from complete shutdown to 20 GW in a few milliseconds. It also jumped over 9 feet (2.7 m) in the air. 3: 22: 4 October 5, 1966: Frenchtown Charter Township, Michigan, United States: Meltdown of some fuel elements in the Fermi 1 Reactor at the Enrico Fermi Nuclear Generating Station.

    Potential solutions include randomly shuffling training examples, by using a numerical optimization algorithm that does not take too large steps when changing the network connections following an example, grouping examples in so-called mini-batches and/or introducing a recursive least squares algorithm for CMAC.

    But those in the class of delinquent (criminals, deviants, etc.) should be eliminated from society ("Folkways", 1907). However, methods of eugenics were applied to reformulate more restrictive definitions of white racial purity in existing state laws banning interracial marriage : the so-called anti-miscegenation laws .
