Per gli antichi romani superare un corso d'acqua aveva un forte valore sacrale, poiché alterava l'equilibrio naturale delle cose. Pertanto per costruire un ponte occorreva innanzi tutto la presenza di un sacerdote, che da questa funzione prese poi il nome di Pontifex #svagaiature

National Lab (LBNL) results support LK-99 as a room-temperature ambient-pressure superconductor. Simulations published 1 hour ago on arxiv support LK-99 as the holy grail of modern material science and applied physics. (arxiv.org/abs/2307.16892) Here's the plain-english explanation: - The simulations modeled what the original Korean authors proposed was happening to their material - where copper atoms were percolating into a crystal structure and replacing lead atoms, causing the crystal to strain slightly and contract by 0.5%. This unique structure was proposed to allow this amazing property. - @sineatrix from Lawrence Berkeley National Lab simulated this using heavy-duty compute power from the Department of Energy, and looked to see what would happen to the 'electronic structure' of this material, meaning, what are the available conduction pathways in the material. - It turns out that there are conduction pathways for electrons that are in just the right conditions and places that would enable them to 'superconduct'. More specifically, they were close to the 'Fermi Surface' which is like the sea-level of electrical energy, as in '0 ft above sea-level.' It's believed currently that the more conduction pathways close to the Fermi surface, the higher the temperature you can superconduct at (An analogy might be how its easier for planes to fly close to the surface of the ocean due to the 'ground effect' that gives them more lift.) This plot in particular shows the 'bands', or electron pathways, crossing above and below the Fermi surface. - Lastly, these interesting conduction pathways only form when the copper atom percolates into the less likely location in the crystal lattice, or the 'higher energy' binding site. This means the material would be difficult to synthesize since only a small fraction of crystal gets its copper in just the right location. This is insanely bullish for humanity.

Il problema non è tanto che anche qui ha vinto la destra o che il tasso di gente che non è andata a votare è aumentato esponenzialmente, il vero problema è che le persone hanno perso la speranza in un futuro migliore. Questo è il vero problema. Ci accontentiamo della mediocrità.

I can NOT believe it! ❤️ One more cover in Nature!! ❤️ "Twist factor" @prashantksk @kotov_group Chiral molecules are structures that have the same composition but are mirror images of each other. In this week’s issue, Nicholas Kotov and his colleagues use self-assembling nanosheets that form bow-tie-like microparticles to examine whether it is practical to use geometrical measures of chirality for chemical structures. #sciart

How neat. Researchers claim to have found, at long last, an "einstein" tile - a shape that tiles the plane in a pattern that never repeats. First two authors appear to have no academic affiliations. arxiv.org/abs/2303.10798

Very worrying thread by the epidemiologist who rang the alarm on January 25, 2020 (!) with the famous "Holy mother of God" thread about the exploding COVID pandemic. China relentlessly planning a "quick" explosion of the new pandemic to accelerate restoring of productivity.

Hello September and hello to the new series of portraits with selected researchers called "Meet our users". Today let's meet Carlo Antonio Pignedoli from @Empa_CH cscs.ch/publications/stories…

…The #ChiralCrew will also have some low-tech optical rotation experiments @ExRdFestival: paper cup kaleidoscopes! 🌀🤯

…you know what else is chiral? sugar! here’s a *sweet* little demo of optical rotation using corn syrup. 🌀🌈 #ChiralCrew @ExRdFestival

…so far our #ChiralCrew demos have shown how chiral molecules can twist linearly polarised light. when unpolarised light hits these beetle’s shells, the reflected light is circularly polarised (!): and you can see that through that through the LH RH lenses of 3D glasses! 🌈🪲

We "computationals" still have to learn a lot in terms of CGI and presentation skills... amazing on @m6info
