What have you learned today?

Seeing what it starts out as, and what it ends up as -


*mind blown*. Talk about precision, and the heat that must be required to enable forging something that size through it all. To top it off this isn’t exactly a recent process by any industrial measure, which makes it even more impressive.

Thing that stand out the most to me is that it seems like the forging is done in a single go. No reheating. Tho I suppose something that large has a huge thermal mass.

I’m wondering if reheating would change the integrity, ie tempering, strength, etc. to some undesirable value. Seeing the outer crust flaking off when the press hit it leads me to think time is of the essence in a process like this.

It does have an effect on the material properties for sure. I'm not a materials engineer but I took a class on this back in school. Metals like steel are solids composed of a microscopic crystal structure and stuff you do to the metal will change the shape of the crystals, and that will change the properties of the material. Reheating and letting it cool off will change the crystal shape, and so will pressing the steel like in the video. There's a whole field of study that does nothing but try to develop different crystal shapes in metals to get better properties in the final result.

Guessing that must be what metallurgy entails. I’m also wondering, what with the cost, resources and environmental impact of procuring elements used to create steel, if something like this will be what eventually replaces it -

MIT team creates plastic that is “stronger than steel” - Global Construction Review

A team from the Massachusetts Institute of Technology (MIT) has created a polymer that has twice the yield strength of steel, but only a sixth of the density. The plastic…

But, then we’ll have a bunch of plastic covering the surface of earth, along with landfills. *sigh*

I learned anybody who can sing, dance and act is called a "triple threat" in the biz.

I learned that after a bogey (one over par,) Par, Birdie (one under par,) Eagle (two under par,) and the elusive albatross (3 under par) is the incredible rare condor, a hole in one on a par 5, and it's actually happened... only 5 times, which to me, still sounds like too many. That's why no one should golf alone; if something that incredible happened and no one was there to see it, one should act like it never happened because no one would believe them.

Valentine's Day is a day of love, a special day on which we're supposed to make sure that those around us know how much we care for them. But on this day when Cupid is supposed to strike us with his arrow, there are several reasons to think love isn't what it once was in the United States.

Maybe this should also be the new criteria for attaining that coveted AAA-lister status. Or is it just A lister in movies. If so it should just be changed to SAD lister to avoid confusion.

 

[Johnny Novgorod]

Maybe this should also be the new criteria for attaining that coveted AAA-lister status.

It used to be, back when sound in movies was the new hot thing and everybody was making musicals. Suddenly the ability to sing and dance was super coveted by studios who had lots of contracts with good actors who didn't necessarily know how to do either.

These days it boils down to studios wanting to tap into the under 25 female quadrant, so they go plucking young hot pop stars and giving them acting lessons.

The quantum realm is ours for the remoulding!

Strange Quantum Object Successfully Created in The Lab For The First Time

Quantum mechanics – the behavior of the Universe at the smallest of scales – continues to surprise us, with scientists now having been able to successfully create a quantum object called a domain wall in laboratory settings.

Quantum mechanics – the behavior of the Universe at the smallest of scales – continues to surprise us, with scientists now having been able to successfully create a quantum object called a domain wall in laboratory settings.


For the first time, these walls can now be generated in the lab on demand, occurring when atoms stored at very cold temperatures – a scenario known as a Bose-Einstein condensate – group together in domains under certain conditions. The walls are the junctions between these domains.

The researchers creating these domain walls say they could end up shedding new light on many different areas of quantum mechanics, including quantum electronics, quantum memory, and the behavior of exotic quantum particles.

"It's kind of like a sand dune in the desert – it's made up of sand, but the dune acts like an object that behaves differently from individual grains of sand," says physicist Kai-Xuan Yao from the University of Chicago.

There has been previous research into domain walls, but they've never been able to be created at will in the laboratory until now, giving scientists the ability to analyze them in new ways. It turns out they act as independent quantum objects, but not necessarily in the way that scientists would expect them to.

That unexpected behavior means domain walls join a class of objects called emergent phenomena, where particles that join together seem to follow a different set of physics laws than particles that are operating on their own.


One of the unusual observations made by the team is the way that domain walls react to electric fields, something which will need further study to untangle. For now, just being able to produce and manipulate these walls is an important step forward.

"We have a lot of experience in controlling atoms," says physicist Cheng Chin from the University of Chicago. "We know if you push atoms to the right, they will move right. But here, if you push the domain wall to the right, it moves left."

Part of the reason why the discovery is so important is that it could teach us more about how atoms behaved at the very beginning of the Universe's existence: Particles that were once clumped together eventually expanded to form stars and planets, and scientists would like to know exactly how that happened.

This domain wall discovery falls under the umbrella of what's known as dynamical gauge theory – a way to test and compute the dynamics of quantum phenomena in the lab. These discoveries could explain how emergent phenomena operate in everything from materials to the early Universe.

As well as looking backwards though, the researchers are also looking forwards. Once more is understood about how domain walls can be controlled, it could open up opportunities for new quantum technologies.

"There may be applications for this phenomenon in terms of making programmable quantum material or quantum information processors," says Chin.

"It can be used to create a more robust way to store quantum information or enable new functions in materials. But before we can find that out, the first step is to understand how to control them."

Plex sucks. At least for Windows. Couldn't get HDR working in the app, the sound kept disappearing in some videos and it doesn't appear to have any of the types of shortcuts I like from my media player. Can't right-click for options like Audio Track and Subtitle Track; it has the same cumbersome navigation that all the streaming services have. I don't get why so many people use this tool to play movies and shows stored in their own homes.

I could try the app on my TV, but Android navigation is even worse.

At least I can use it to stream my stuff at other people's places, if the opportunity should ever present itself.

I find it amusing that Social Conservatives/Republicans often oppose birth control and abortion, trotting out "If you don't want kids, don't have sex". And then making laws making abortion and conception increasingly difficult to obtain in places like Texas.

And lo and behold......the consequences of our actions!

We could also attribute some of this to the fact nobody seems to be hopeful about the future right now and it's hard to want to have kids when you think/know the future is gonna suck.

What's more amusing is that they're anti-abortion, but pro-death penalty, meaning a clump of cells is more worth life than an unquestionably alive and sentient human being who's been convicted of a capital offence they may or may not have actually committed based on the decision of our very fallible and corrupted judicial system. They're anti-abortion, but pro-limiting social services like welfare and affordable healthcare, so when unwanted babies are born, "yer on yer own, you lazy, irresponsible mooch!" I'm not partisan by any stretch, but were I to be forced to pick a side, I'd most certainly go with the any that doesn't deal in ridiculous absolutes that dictate other people's lives because of "my" values.
