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.

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.”

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.

Thank you! Super helpful for someone like me just switching over.

He is not yet out. His term ends in a few months and this is the nomination to replace him.

A key finding from the survey is that the galaxies are maturing faster in several ways than researchers previously believed. For one, the galaxies are more chemically enriched than expected, which means they have produced more heavy elements, in particular carbon and oxygen, than was thought possible during this early age of the cosmos.

As galaxies evolve, pockets of gas within them condense and ignite into stars. The new stars churn out heavy elements like carbon, which then become building blocks for the next generation of stars. Ultimately, these heavy elements (referred to as metals in astronomy) are required to make planetary systems, and even humans, in the case of our own solar system.

“How do metals form in less than 1 billion years? It was a surprise to see such chemically mature galaxies,” Faisst says. “It’s like seeing 2-year-old children act like teenagers.”

I am not sure if I should hate agreeing with people I hate.

I don’t quite agree with your assessment. There are not a whole lot of mechanisms in the constitution for “the people” do more than vote every couple of years or violently opposed the elected government. Look at fetterman and sinema. Both turn from what seemed to be progressive candidates to the main reason several legislative things fell through. I’m sure several people wish they could do something more immediate than wait until their term is up.

It doesn’t work when you don’t have a defined mechanism to enforce the balance after the check. These historical documents were written when your word meant something. Like they said above it works when people are doing things in good faith.

Third Rock. I’m not usually a fan of slapstick style comedy, but John Lithgow has the perfect delivery, timing, and enthusiasm in just about every line Dick Solomon says.

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!

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.

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!

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.

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