- Comment on What do you think of this movie ?? 2 weeks ago:
I saw it. I liked it. It isn’t my favourite Spielberg film, but it was fine. I thought it lacked a little bit in exposition, but the overall plat and pacing was good.
spoiler
Steven Spielberg really likes generic Grey Aliens. Close Encounters of the Third Kind, Kingdom of the Crystal Skull, this film…
The music was excellent. There was a French Horn blast during one of the action sequences which made me think “that sounds like John Williams!”. But as Williams had announced his retirement after Indiana Jones 5, I wondered who Spielberg got as a composer…
When the credits rolled, it turned out that Spielberg coaxed the nonagenarian out of retirement for another film score :)

How the mini-universe works
Barontini used a cloud of 24,000 ultracold atoms—just a few billionths of a degree above absolute zero—to create a hermetically sealed quantum system that mimics a simple “universe.”
Okay, so they didn’t create a new universe. They just sectioned off a portion of the universe we already have, and did experiments on it. Still neat, though.

He’s the person who holds the exclusive rights to use vantablack in art.

Didn’t the person who developed the “pinkest pink” allow everyone to use it… except for the guy who tried to restrict vantablack, as a reciprocal !fuckyouinparticular@lemmy.world?
Edit: LOL, that exact story is one of the top posts on that sub.

No, Nancy (Grace) Roman: en.wikipedia.org/wiki/Nancy_Roman

- Comment on Every Signal We've Ever Sent Into Space 1 month ago:
I wonder how extraterrestrials would react to the moon landing.
If they’re technologically advanced enough to build radio telescope of sufficient size to detect such weak signals, they’d probably think we were cute. Like how we feel when we observe a crow or a squirrel solve a puzzle or navigate an obstacle course.

Not for me.
Article text
Researchers in the University of Minnesota Twin Cities have discovered a powerful new way to control the electronic behavior of a metal—by manipulating the atomic properties of materials where they meet. The study, published in Nature Communications, demonstrates that interfacial polarization can tune the surface work function of metallic ruthenium dioxide (RuO2) by more than 1 electron volt (eV)—a tiny amount of energy—simply by adjusting film thickness at the nanometer scale. “We often think of polarization as something that belongs to insulators or ferroelectrics—not metals,” said Bharat Jalan, professor and Shell Chair in the Department of Chemical Engineering and Materials Science at the University of Minnesota. “Our work shows that, through careful interface design, you can stabilize polarization in a metallic system and use it as a knob to tune electronic properties. This opens an entirely new way of thinking about controlling metals.” This specific change is most powerful when the metal layer is about 4 nanometers thick—roughly the width of a single strand of DNA. At this precise size, the metal shifts from being “stretched” by the material underneath it to a more “relaxed” state. This transition proves that the physical way atoms are packed together has a direct, measurable impact on how the metal handles electricity. “This was surprising,” said Seung Gyo Jeong, first author of the study and a researcher in Jalan’s group. “We expected subtle interface effects, but not such a large and controllable change in work function. Being able to visualize the polar displacements at the atomic scale and connect them directly to electronic measurements was especially exciting.” Beyond fundamental physics, the findings could impact the design of next-generation electronic, catalytic and quantum devices. In addition to Jalan and Low, the research team included members from the Department of Chemical Engineering and Materials Science at the University of Minnesota-Twin Cities, Massachusetts Institute of Technology, Texas A&M University, Gwangju Institute of Science and Technology and the School of Physics at the University of Minnesota-Twin Cities.
The original paper also appears to be open access.

- Comment on Australia struggling with oversupply of solar power 1 year ago:
or that the idea of turning them off is simply inconceivable (why would I turn mine off and let others make money)
If that’s the issue, it seems like time-of-use rates or smart metering could be an easy solution. If the price of electricity were negative during periods of oversupply, I bet people would figure out how to disconnect their solar panels pretty quickly. This would simultaneously incentivize energy storage projects.

This seems like a good problem to have, no? Just need some batteries or some interuptable industrial processes to absorb the excess.
