Scientists use pressure to make liquid magnetism breakthrough

It sounds like a riddle: What do you get if you take two small diamonds, put a small magnetic crystal between them and squeeze them together very slowly?

The answer is a magnetic liquid, which seems counterintuitive. Liquids become solids under pressure, but not generally the other way around. But this unusual pivotal discovery, unveiled by a team of researchers working at the Advanced Photon Source (APS), a U.S. Department of Energy (DOE) Office of Science User Facility at DOE's Argonne National Laboratory, may provide scientists with new insight into high-temperature superconductivity and quantum computing.

Though scientists and engineers have been making use of superconducting materials for decades, the exact process by which high-temperature superconductors conduct electricity without resistance remains a quantum mechanical mystery. The telltale signs of a superconductor are a loss of resistance and a loss of magnetism. High-temperature superconductors can operate at temperatures above those of liquid nitrogen (−320 degrees Fahrenheit), making them attractive for lossless transmission lines in power grids and other applications in the energy sector.

What does this screen show in terms of numbers and abbreviations? Why is there a change in the color/shading of the image?

Why isn’t the image very clear since this was supposedly a US fighter jet chasing the object and in a combat situation, you don’t want unclear images of a supposed enemy.

I’ve never been happy with the narrative that went with this film (it’s the lack of a real informational narrative that bothers me - coverup, fake, misinterpreted image, etc).

Looks like a bedbug was setting on the lens.

[sit-rep]

when has a picture of a UFO ever been clear??

[Spktyr]

The change in color/shading is a screen inversion of thermal data. IR camera displays can have contrast issues, so users can change from whiter/brighter = hotter or darker/blacker = hotter so you can better pick out the target against the background.

[Spktyr]

Also, at the top center you can see the camera is in IR mode, and you can see that the IR sensor is rapidly panning to track the object (the numeric display is the bearing onto the target displayed in degrees.)

Also, IR is not the sharpest in most atmospheric conditions.

Not a bug but a feature!

[LesbianThespianGymnasticMidget]

The colors change as the pilot flips through the spectrum. Visible light, infrared, etc. I am sure the color (hue) change is left as a Poka-yoke for the pilot to know what mode he is in (it is displayed as well) because that can easily be changed with a digital filter.

The object is far away hence the resolution is low. Air interferes with resolution at a distance plus the number of receptors in a camera when digitally zoomed in displayed on the screen drops. Think of zooming in on one of the massive images on the web. When you zoom in it starts getting blocky at some point. What you are seeing is a tiny portion of the cameras field of view. Zoomed out it is clear. Zoomed in it is blocky.

What does the 2015 Super Hornet chasing a “Tic Tack” have to do with pressure to make liquid magnetism breakthrough?

Liquid magnetism, or superconductivity, demonstrates anti-gravity effects. Superconductors, electrically charge lift off of tables due to the earths magnetic field.

So...Tic Tac UFO could be using liquid magnetism propulsion.

Liquids become solids under pressure, but not generally the other way around.

Uh, that's not what I was taught in High School Physics...

Another stupid reporter who knows nothing about science.

I was thinking Abba from the last airbender.

[Yo-Yo]

To be fair, I hadn't Read The Fine Article. They're talking extreme pressures, so the triple point graph of water I posted doesn't really apply.

And see it disappear they did, at around 20 gigapascals—equivalent to 200,000 atmospheres, or about 200 times more pressure than can be found at the bottom of the Mariana Trench in the Pacific Ocean, the deepest trench on Earth. The spins of the electrons remained correlated over short distances, like a liquid, but remained disordered even at temperatures as low as 1.5 Kelvin (−457 degrees Fahrenheit).

[PIF]

OK but that so O/T
they could also be using zero point propulsion as easily

or, as one critic clams, the object is actually a bird, but because of the way the background is presented and the planes own motion, the object appears to move very rapidly - but claim does not account for close visual sighting by pilots

[rightwingcrazy]

There’s talk about “liquid diamond” deep in Jupiter and Saturn, albeit at very high temperatures.

That must be how Skynet made that cop in T2.
