KJ

Thank you 100 times over to the @doodles team and @evankeast … life changing.

@jeffreygwei Still holding my two sticky’s from when it first launched 🤙🏼

gm gm Important notice to NOT buy this. Remove all offers too. I love to see the floor being alive again but we need to move to a new contract and cap supply. These sit on an old contract and I didn't expect the sudden demand. Information in announcement channel in Discord. Don't get rekt!

@dbarawn When it comes to semiconductors, which companies do you believe have the best shot at advancing the technology over the next 5+ years?

@RetireByDoodles Towards a room temperature superconductor? No, because if this is one (which I highly doubt), no one knows how to make it outside of the Korean group.

LK-99: The Case for Skepticism By now there's been a number of replications, videos, pre-prints on arxiv, and at-home or at-work attempts to reproduce the original findings of Lee and Kim. Here's why I'm increasingly skeptical on LK-99 and my reasoning: #1 - The Videos There's been a number of videos produced and circulating the internet showing partial levitation or full levitation, the kind of thing you see in cryogenic superconductors that 'quantum lock' or 'flux pin' and float in mid-air. The issue with all these videos is that the visual behavior is completely indistinguishable from a diamagnetic. I was initially under the impression that you could not produce stable levitation from two simple dipoles, according to a time-honored theorem from physics by Earnshaw, and so levitation above a single magnet was 'proof positive'. However, as it turns out, there is a less well-known exception to this rule called Brauenbecker extension which provides a mathematical proof that levitation is possible with a simple diamagnetic in a dipole field so long as the diamagnetic material mass is very small relative to the strength of the magnetic field. (Note that there are plenty of videos of a diamagnetic floating above a grid of magnets, but those magnets have a more complicated field than a dipole and so Earnshaw's theorem does not apply. Here is the derivation of Brauenbecker's result for the curious: cds.cern.ch/record/535810/… ) The suspicious thing in the levitation of LK-99 videos is that the 'stable equilibrium point' is directly above the center of the magnet. This is what you'd expect via the Brauenbecker derivation - that the only stable point is in the center. A flux-pinned super conductor could levitate in many different orientations including off to the side of the magnet. Conclusion - the videos do NOT show flux-pinning. #2 The Simplest Measurements are Missing By now there have been several replications of the material by laboratories of professional scientists with high quality equipment that yield a high purity of LK-99, higher purity than the original reports by Lee and Kim. None of these measurements have accomplished the most direct and obvious result of room-temperature superconductivity, which is zero resistance at room-temperature. Lee and Kim's original paper had badly formatted plots, not the best choice of plot axes, and in general it was overall rushed to arxiv. They reported absolute resistance but not physical dimensions of the sample, and claimed a resistivity in the text of their article that was on the order of a superconductor but it isn't clear where that calculation came from. Subsequent teams have published results claiming 'zero resistance' but at 110K - which is great, but not that impressive - tons of materials superconduct at very low temperatures and so it is not indicative of much special about LK-99. Conclusion - Measurements are the proof and they haven't materialized #3 - Simulations are suggestive and not predictive Much of my initial enthusiasm came from reading simulations performed by well-respected scientists like @sineatrix at LBNL and others are University of Boulder Colorado and TU Wien - their results didn't rule out LK-99 entirely! I thought this was incredible. However, this was always tempered by the knowledge that the physical properties as measured by lab equipment would be soon to follow and support the proposed mechanisms of superconductivity as described in the preprints on simulations. Notably those simulation results are also congruent with other more mundane interpretations like magnetism and diamagnetism, as mentioned by the original authors themselves. Conclusion - Simulations are suggestive but we don't live in a simulation ~~~~~~~~~ Overall Takeaway: I first wrote about my initial take on the LK-99 publication in this tweet here: x.com/andercot/statu… I expressed a few concerns in that original tweet and so far none of them have been adequately addressed, despite several replication attempts and follow-ups. If this material was the holy grail of materials science then it seems likely at least some of the missing results would have manifested by now. Summary: - Videos are explainable by more mundane everyday effects - Key measurements are missing - Simulations are nice but we don't live in one. ~~~~~~~~~~ As I've said before I'm deferring any real conclusions until the results of Argonne National Lab, but right now my mental model is: LK-99 is a diamagnetic semiconductor. This doesn't change my conviction that ambient-pressure room-temperature superconductors can very well be discovered and manufactured at-scale within our lifetimes, and that such a development would be a watershed moment for humanity.

@dbarawn So in your opinion, is American Semiconductor making legitimate progress?

@ArthurB @Andercot This is confusing multipole expansion (e.g. spherical harmonics) about a point with arbitrary configuration of magnetic dipoles. Yes, arbitrary field's harmonic expansion will require higher than l=2 terms. But you can also represent it as a configuration of dipoles in space.

@ScottSh5000 @akafacehots So where are your facts then? 😵‍💫

@akafacehots Fact check: TRUE 🔥🔥🔥🔥

@CharliCohen @RSTLSSxyz @clairesilver

have an annoying amount of cool shit I want to share with you guys and can’t yet 🥹 @RSTLSSxyz x @clairesilver is going to be wild

@rishi1969 @Derivatives_Ape Nothing you said was based on fact. It was all “what if’s” and wishful thinking. If you could provide some concrete evidence I’d be more inclined to entertain it, but without the yuan becoming the #1 reserve currency none of your wishes will come true.

@RetireByDoodles @Derivatives_Ape 3. North America as a whole needs to open their eyes and get their priorities straight and shift focus from they/them stuff. US is literally on its way to be the next U.K. U.K. is still developed but just not as important to the world. Same would happen to the U.S.

Top nation states China, GCC & Russia are sticking together more than ever recently. They collectively look at the US in disgust. Just look at all the homelessness, drug addiction and rampant crime. USA is truly a 3rd world country in comparison to the others.

@rishi1969 @Derivatives_Ape In order for that to happen, the yuan would need to become the global reserve currency, and it’s not even a top 5 so good luck there. Also, 2/3 of China’s workforce doesn’t have a high school education, and the US has a GDP per capita 6x that of China’s.

@rishi1969 @Derivatives_Ape 5-10 years? What is collapsing? Would be open to the idea if you’d be able to provide facts to back up that wild claim.

@RetireByDoodles @Derivatives_Ape Give it 5-10 years, you won’t say the same thing. Collapse takes years to finish.

@Legend You mean “sayonara”, right?

@phomo_eth Happy to still be around with you phomo!

@RetireByDoodles i know that name, gm KJ 👀 haven’t gone full rabbit hole on that one but plan on doing what i need to secure if possible

see a lot of @clairesilver stories & thought i’d tell how i acquired the 2 genesis @braindrops_art works below it’s Nov 15th 2021, peak bull eth is $4560, 120 gwei is low… 👈 ‘mary in the black & white room’ ‘amalgam’ 👉

@k2_nft I minted and look forward to following along 🤙🏼

@TheMSingh @EverydaySpy @lexfridman @EverydaySpy Since it’s been 6 months from when this aired, do you have an updated assessment? You mentioned Odessa would be taken by the fall, but we’re almost into Spring and Russian positions are almost the exact same as September so the assessment ended up not coming true.

@ajv @vandemlau @garyvee Embarrassed to admit that I always thought you were Gary’s son, not brother. On the plus side, you both age like a fine bottle of wine🍷 so…

@vandemlau @garyvee Yes. The investment amount is directly correlated to the amount of equity you receive. In some instances you can receive official advisory shares. That was not the case for Gary and I.

1) jumping in along with the others to clarify my initial commitment to invest $10k and @garyvee and his initial commitment to invest $25k into flux

@blockworks @michael_bodley They first start with NFT payments in USD, then roll out to accepting crypto soon after. It is supposed to be a Q1 launch but may be getting pushed back.

SCOOP: Amazon is coming to Web3, according to multiple sources. How long could they stay on the sidelines, as millions of consumers see the value of NFTs? Exclusive from @michael_bodley blockworks.co/news/amazon-nf…

@defitoast @doodles I’ll never forget that 🙌🏼

Lots of @doodles FUD going around these days. I still remember how awesome the founders were right after reveal to buy their beautiful mascot from a community member for 100 ETH. People forget… but I won’t 🫡

@leanpockets @xPeaceLandBread @doodles Lol well I bought at 0.95 originally so a 12x return is worthy of congrats I guess. It’s all good, I’ll find another one and continue on this journey.

@RetireByDoodles @xPeaceLandBread @doodles dunno if that's an oof or a congrats so i guess take your pick?

Just purchased a 2nd @doodles 😳 🤠 Doodles are one of the only utility pfp projects I'm betting on, and the first I own 2 units of. To me, Doodles is the only pfp with the art & team to become a global brand. If achieved... RIP those fading 💀🪦

@leanpockets @xPeaceLandBread @doodles I didn’t want to! I listed 4e above floor a few weeks ago not thinking anyone would grab it and it would expire. Bittersweet sale. Now I need to grab another dood 🤔

@xPeaceLandBread @doodles Damn dude that cowboy is goated, a grail fr. Tbh surprised @RetireByDoodles let it go

@zergdonkey @Createra_ 8 hours later…

Genesis Land in @Createra_ is experiencing the beginnings of a sell-side liquidity crisis. It has always been like oil on crack. Production is entirely inelastic, demand meanwhile, is reflexive.
