There's a lot of conversation taking place around this LK99 room-temperature ambient-pressure superconductor. This would have MASSIVE engineering implication if true. I have no clue what's real at this point. Thanks to nostr:npub1zh36wt34eav4tugmd3r7f4tr99suj6p9ps2ezneugdvyfvrw3rpqtx4qq9 (My most trusted and astute technology advisor) for sharing this post from Andrew Cote on Twitter. Here's what he said about it:

"Simulations published 1 hour ago on arxiv support LK-99 as the holy grail of modern material science and applied physics.

(https://arxiv.org/abs/2307.16892)

Here's the plain-english explanation:

- The simulations modeled what the original Korean authors proposed was happening to their material - where copper atoms were percolating into a crystal structure and replacing lead atoms, causing the crystal to strain slightly and contract by 0.5%. This unique structure was proposed to allow this amazing property.

-

@sineatrix

from Lawrence Berkeley National Lab simulated this using heavy-duty compute power from the Department of Energy, and looked to see what would happen to the 'electronic structure' of this material, meaning, what are the available conduction pathways in the material.

- It turns out that there are conduction pathways for electrons that are in just the right conditions and places that would enable them to 'superconduct'. More specifically, they were close to the 'Fermi Surface' which is like the sea-level of electrical energy, as in '0 ft above sea-level.' It's believed currently that the more conduction pathways close to the Fermi surface, the higher the temperature you can superconduct at (An analogy might be how its easier for planes to fly close to the surface of the ocean due to the 'ground effect' that gives them more lift.)

This plot in particular shows the 'bands', or electron pathways, crossing above and below the Fermi surface.

- Lastly, these interesting conduction pathways only form when the copper atom percolates into the less likely location in the crystal lattice, or the 'higher energy' binding site. This means the material would be difficult to synthesize since only a small fraction of crystal gets its copper in just the right location.

If it wasn't clear why this is a big deal, if successful LK-99 would be a watershed moment for humanity easily on-par with invention of the transistor, here's why: https://twitter.com/Andercot/status/1685088625187495936?s=20

As an additional note (This is Preston again), I got a really interesting message from fellow Bitcoiner, Phil Champagne, about something seemingly unrelated to this LK99 stuff, but oddly relevant. It's a white paper that suggests gravity is actually formed from a dipole by the elliptic form atoms take. This could potentially explain why gravity is a fraction of the electric force since it would be derived from it. Here's a link to the paper: https://vixra.org/pdf/1608.0426v6.pdf and here's a link to a youtube video talking about the paper: https://www.youtube.com/watch?v=mCxw3PEes4M

If you have questions about this paper, you could ask Phil (https://twitter.com/egg_descrambler) about it, here seems really well versed on the subject. BUT, if you want a REALLY "interesting" response definitely go to my trusted technical advisor, Greg Zaj.

Using a number of various models/risk tolerances they create different frames for investing in BTC. Toward the end of the paper they suggest a 9.5% allocation as optimal.

9.5% of only Blackrock's investment capital is roughly $1 Trillion

...

The current BTC market cap is $570 Billion. Among other banks and financial institutions, that should raise some eyebrows to say the least. 👀

I downloaded and have it available for anyone who was looking for it 👇🏻
