JCC Go science?

That's too bad, but let's wait and see.

IF it's true, or comes true soon, what could the realistic ramifications be?

 

Well, if the model is correct, room temperature superconductors.

 

You'd have to be able to produce it in bulk before it really changed anything for consumers and that sounds... a ways off.

 

shhh ramza no engineering only science bby

 

Superconductor switches in research machines already happened, man, it's engineers all the way down from there.

 

Hydrogen/Oxygen rockets have a Specific Impulse (Isp) of up top 450. A few chemical reactions can be a little higher but they are very toxic. In space that would make little difference though but they are not going to be used as Earth launch vehicles. The highest comes from a combo of lithium, fluorine, and hydrogen of something like 540. A metallic hydrogen rocket could have an Isp of 1700. This is a DeltaV budget increase of 3.77 over hydrogen/oxygen.

Lord Vivec -- discuss?

 

This is pretty cool. I don't have access to the journal it's published in, which I really wish I had because I know a thing or two about quasiparticles in conducting materials. This is now, what, the second time we've seen this effect in materials? I'm beginning to wonder if we may see a series of materials like this, and what that means for solid state physics.

The Berkeley article had a good tidbit that's relevant:

"By tuning its thermal conductivity, the material can efficiently and automatically dissipate heat in the hot summer because it will have high thermal conductivity, but prevent heat loss in the cold winter because of its low thermal conductivity at lower temperatures."

That's a very interesting effect to have in technology.

Regarding the law of physics it breaks, IIRC it's the kind of law that's empirically show from experiment, meaning that violations from experiment are a lot less severe than a law that's derived from theory. This is because it's a law born from observation.

 

This is more "go math" but Ramza

I'd say my immediate beef is the layout, and the actual video addresses that, so... yeah, solid high level synopsis, for the most part. There are a few weird assertions - the glaring one for me was the statement that category theory attempts to answer completeness when, in fact, it was formalized over a decade after Gödel's incompleteness result was published, and to a lesser extent the divorcing of a discussion of cardinal numbers from set theory when the two concepts are so intertwined that anyone who studies cardinal numbers is considered a set theorist is a weird choice. Admittedly those probably stand out the most to me because they're in Foundations, which is my jam.

 

The problem is that whenever someone says that, all I can think about is the shower scene in the first Pitch Perfect. This is my cross to bear, I suppose...

 

An old family friend did the proof for the four color map theorem. I don't know where that fits on the infographic.

 

These days it's usually considered a graph theoretic theorem, but the actual proof uses a wide range of techniques (also it's massive).

Appel or Haken, incidentally?

 

Wolfgang Haken. I know his son.

 

When I was in high school I came up with a longer and more complicated way of squaring two digit numbers.

 

Another one for Lord Vivec -- discuss!

Is this really the "holy grail" of physics?

 

There's cause to have skepticism for this result and I'd wait until another test is done. But no, this isn't the holy grail lmao. This isn't even a dungeon clearing reward.

A new subspecies of polar bear, that locals have long referred to as the King Bear, might be officially "discovered" after finding a skull. With locals still sometimes reporting seeing "king bears," then hopefully that means this subspecies is still around and just very elusive!

A possible major reclassification of dinosaurs (if it ends up being accepted):

(T. rex would end up being considered more closely related to Triceratops than Diplodocus, under this system)

 

Negative mass fluid

Replication needed.

 

Makes sense to me, especially in light of archeological evidence that Velociraptors had feathers.

And evidently, Brontosaurus is now a thing again. https://blogs.scientificamerican.com/tetrapod-zoology/that-brontosaurus-thing/

 

BAH! really wish this was in arXiv.

 

This is me if I were an Iranian-Canadian electrical engineer and made youtube videos
