An affordable, water-resistant packable backpack for travel and day hikes

Our verdictThe Sea to Summit Ultra-Sil Dry Daypack is an affordable packable travel daypack that works as a functional backup bag without taking up too much room. It packs compactly into a very small Ultra-Sil stuff sack that includes a handy aluminium carabiner to clip onto your primary bag, purse, sling, or larger backpack. It is designed for travelers who want a lightweight stuff sack rather than a structured daypack or backpack. We tested the Sea to Summit Ultra-Sil Dry Daypack on a week-long trip to Germany that involved city tours, casual hiking, and a short run. We even used it for three months on weekend trips to Chicago, taking it to farmers markets, on bike rides, and on errands around town. It has one main compartment that can hold items like jackets, caps, snacks, and knick-knacks. The bag performed flawlessly in terms of durability and comfort for carrying for short periods of time as well as a 5-mile hike. It is easy to open with a roll-top closure and pack away when not in use. The bungy cords on the front are convenient to store quick-access items like a rain jacket or a hat.

Quantum System's Evolution Defies Standard Approximation - Quantum Zeitgeist

Matias Ginzburg of Scuola Internazionale Superiore di Studi Avanzati, Simone Rademacher of LMU Munich and Giacomo De Palma of University of Bologna have demonstrated a fundamental limitation in a widely used simplification of quantum dynamics. The researchers analytically solved a model of N bosonic qubits governed by a purely anti-Hermitian Hamiltonian, revealing that the standard mean-field Hartree approximation fails to accurately predict the system’s behavior as the number of qubits increases. This failure occurs even in the thermodynamic limit, challenging the validity of the Hartree approximation for non-Hermitian Hamiltonians and potentially impacting a quantum algorithm designed to solve nonlinear differential equations. Their findings call for additional conditions to ensure the accuracy of mean-field models in bosonic many-body systems.

Samsung all but confirms iPhone Duo is goosing Galaxy Z8 sales - Ars Technica

Samsung released its first foldable phone in 2019, and it was the only company seriously pursuing the form factor for several years. Those early devices were clunky and more interesting as feats of engineering than as things you’d want to carry around all day, but little by little, foldable hardware improved until Apple could finally release the product it wanted. The iPhone Duo is not an island—it relies on many of the same components as other foldable phones, including Samsung displays. The iPhone Duo may lead to wider foldables (and bigger hands, apparently).
