LG’s Wing is a weird, surprisingly practical smartphone

When it comes to offering more screen real estate on a smartphone, manufacturers have two options: either go with a flexible display à la Samsung’s Galaxy Z Fold 2, or attach a secondary screen like the LG Velvet. While the latter is obviously the easier (and cheaper) option, both implementations have a common problem: multi-tasking only works well when both apps are in portrait orientation, due to the design of most apps.

This can be a big problem. If I watch YouTube and Netflix videos in landscape, but then load Twitter or Facebook on the bottom half of the phone, these would be stretched wide, making it difficult to read text or view images. This is where the LG Wing 5G’s bizarre swivel-screen design comes in, and having used a pre-production unit for about a week (and having used both the Velvet and the Galaxy Fold), this

Spin clean-up method brings practical quantum computers closer to reality — ScienceDaily

Quantum computers are the new frontier in advanced research technology, with potential applications such as performing critical calculations, protecting financial assets, or predicting molecular behavior in pharmaceuticals. Researchers from Osaka City University have now solved a major problem hindering large-scale quantum computers from practical use: precise and accurate predictions of atomic and molecular behavior.

They published their method to remove extraneous information from quantum chemical calculations on Sept. 17 as an advanced online article in Physical Chemistry Chemical Physics, a journal of the Royal Society of Chemistry.

“One of the most anticipated applications of quantum computers is electronic structure simulations of atoms and molecules,” said paper authors Kenji Sugisaki, Lecturer and Takeji Takui, Professor Emeritus in the Department of Chemistry and Molecular Materials Science in Osaka City University’s Graduate School of Science.

Quantum chemical calculations are ubiquitous across scientific disciplines, including pharmaceutical therapy development and materials research. All of
