  • How to Watch Artemis 2, NASA's First Crewed Mission to the Moon in 54 Years

    Jump

  • For those who do not know, NASA has an app and they post a bunch of photos and will probably be streaming this as well. The app is free and surprisingly well done.

  • Researchers prove that atomic vibrations can transfer orbital angular momentum directly to electrons in a non-magnetic material

    Jump

  • The study’s innovation was using the natural symmetry and vibrations of atoms to control the orbital momentum of electrons. Atoms in a solid are tightly packed together in lattice-like structures, whose shape depends on the material. In some materials, like metals, the atoms are arranged in a cube pattern, stacking together symmetrically so that their mirror image superimposes perfectly.

    In chiral materials, such as quartz, the atoms are arranged in a helical pattern, like the threads of a screw. The atoms stack together with a built-in twist with either a “left-” or “right-” handedness that can’t superimpose onto each other, a symmetry called chirality. Human hands are a classic example of chiral symmetry—hold them out with the palms facing up, then put one on top of the other. That’s chiral!

    Now, onto chiral phonons. Individual atoms vibrate in place while staying in a fixed position. In symmetrical materials like metals, the atoms wiggle side-to-side. In chiral materials, the twisted lattice structure forces the atoms to naturally wobble in a screw-like pattern with right- or left-handedness.

    Phonons are the collective vibrations that travel through a solid, like a ripple moving through its atoms. Chiral materials have chiral phonons. Imagine you’re in the pit at a rock concert when the ballad hits. Someone starts swaying, hands in the air, forcing their neighbor to sway, and so on until the wave pattern ripples through the crowd.

    The fact that the atoms vibrate in a circular, chiral path means that the atoms themselves naturally have an angular momentum. The study is the first to show that the chiral phonons’ angular momentum is transferred directly to the electrons’ orbital angular momentum.

  • Disaster can sway votes but won't deliver climate action, study shows

    Jump

  • Dr. Malavasi states, "One key takeaway to me is that experiencing climate change, weather anomalies, or surviving climate disasters does not increase support for climate policies 'enough.' The natural question is, 'what do we do about this?' and to me, the answer is stronger leadership."

  • How much do you need to retire early?

    Jump

  • Your question is too vague. It all depends on what you consider an acceptable lifestyle and also what area of the world plays a huge part.

  • Mexican cartels overpower police with ammunition made for the US military

    Jump

  • I think the person you are responding to means that while it is legal for civilians to purchase in the US they do not believe it is legal for anyone in Mexico but the Mexican military to possess

  • You did read where they said charismatic, right?

    Vance's "charisma" couldn't fight it's way out of a paper bag.

  • Brazil President Bolsonaro was arrested. Good morning to Brazilian reporter Manuela Borges, who’s been waiting 11 years for this petty moment. ❤️ 🇧🇷

  • Milky Way shows gamma ray excess due to dark matter annihilation, study suggests

    Jump

  • New research shows that dark matter has a different distribution in our galaxy than previously thought, and that advances dark matter's status as a potential source of the observed gamma ray excess in the Milky Way's center. High-resolution simulations reveal that the dark matter distribution in the inner galaxy is not spherical, but flattened and asymmetrical. The findings confirm the theory that the gamma ray excess is due to dark matter annihilation.

  • The nazi call is coming from inside the House!

  • People who don't/can't sleep when they're "supposed to", why? What do you do during this time?

    Jump

  • They are not very accurate. You're more likely to get yelled at by a NCO(non commissioned officer) than by an officer on a day to day basis. Most officers are like middle managers until you hit the O-5 to O-6 rank. Officers give out orders, NCOs carryout orders using junior enlisted personnel. Most harassment stops outside of basic/advanced training, unless someone in your unit gets in trouble and then they might do a mass punishment where everyone is cleaning the barracks on a Friday night or over the weekend. I'm white, so I can't speak much to the discrimination part, other than it didn't happen much in the jobs that I was in. I'm positive it happens, but it didn't happen out in the open when I was in. Obviously the current administration for the US government is changing that a bit. I can't speak for the person you asked the question to, but I had two combat deployments and two trips to South Korea, with a solid bit of PTSD from the deployments.

  • Trump can’t let go of Nobel Peace Prize despite epic snub

    Jump

  • Words have lost all meaning. Brutal to point out character flaws that everyone already knows about and epic that they talk it about openly. SLAMMED!

  • Trump can’t let go of Nobel Peace Prize despite epic snub

    Jump

  • But that just tells me he's not the first, only, or likely last person to solicit something he isn't qualified for from this committee. Not exactly epic if they are just stating the obvious out loud.

  • Trump can’t let go of Nobel Peace Prize despite epic snub

    Jump

  • "epic snub" seems a little exaggerated for something that fat orange fascist was never qualified for in the first place.

  • House of South Carolina judge criticized by Trump administration set ablaze

    Jump

  • Well, anything digital comes to mind. Cutting undersea communication cables is another. But you can generally look in the direction of Russia for most of it. In the US they have corrupted an entire political party with out drawing any "front lines"

    Russian interference

  • American politicians are freaking out about homicides on public transit

    Jump

  • The graph shows deaths. I'm sure there are quite a few more collisions that don't end in death, but possibly severe and lasting disabilities. You don't see a lot of subway cars colliding with other subway cars. I'm sure plenty of people run into buses though.
