The year we realized that Crypto was all a fraud
The most interesting phenomenon revealed so far is that the room-temperature superconductor people and the generative-LLMs-are-God people draw on the same limited global pool of credulity, such that HN cannot be flooded with both ChatGPT worship and superconductor speculation at the same time.
As someone strongly in the first camp and not the second, this feels like a very odd observation. I despise generative LLMs and avoid using them at every opportunity. I'm also spending all my free time this week perusing arxiv preprints and Twitter threads. Make of my datum what you will. :)

Serious question- I saw the original video, where once they stopped waving the magnet around and held it near the sheet of LK-99, it looked to me like it stayed at a specific standoff distance, with no decay. Assuming no videographic trickery, what else could it be, other than the Meissner effect?
A diamagnetic material. "In simple terms, diamagnetic materials are substances that are usually repelled by a magnetic field. Electrons in an atom revolve around the nucleus, and thus possess orbital angular momentum. The resultant magnetic momentum in an atom of the diamagnetic material is zero."

> I despise generative LLMs and avoid using them at every opportunity. why? it's just a tool. despise how it was released, how it was trained, the people that operate it , whatever, but I can't really understand why someone would 'despise' a wrench -- even if it was used really poorly and produced by a shady company with a checkered past.

Regarding #1, it pains me to see so much hype about this feat. To restate it. We were able to simulate the implosion of the secondary stage of a thermonuclear device in a lab by the means of lasers, to the point that this simulation has ~ 0.001% the efficiency of a real device. We also probably learned a lot about the amplification of x-rays by the casing material that would have been useful during the SDI days of th…
> It was a weapons test, by a weapons lab Beyond a certain point, every energy system is a weapon first. Uncontrolled precedes controlled.

Perhaps, but the reverse engineering efforts you mention may have already led to incredible breakthroughs over the past few decades. Lasers, integrated circuits, Kevlar, fiber optics, and more technologies were said to have been seeded among the research community based on recovered UAP components. This is based on Army Colonel Philip Corso’s account in his memoir, “The Day After Roswell”. [1] [1] https://en.wikipedi…
I know that. I used to believe that too. I really wanted to believe all the SSP stuff (Corey Goode, David Wilcock, et al). However, my view is now that all of the talk over advanced tech has actually been a propaganda/influence/information-warfare campaign to: 1) assert that gov/corp is in control when it's in fact not; pretend it's not at all challenged by superior species, not at all ignorant of 1000s-of-years-more…
This ongoing research saga pretty much the most excited I’ve been about anything since before Covid. It feels like the science equivalent of watching your favorite sports team on an epic rise towards winning a world championship. Even if this turns out to flop, I hope history remembers the original authors favorably. They really did find something that by all accounts could plausibly be a room temp superconductor. An…
Just curious, how did you find Covid "exciting"? Making lots of money on the bear market?
Of course it for tedious very quickly, but I remember going to the park and people being told not to sit on benches by police on horseback. How is that not crazy and sort of exciting?
I got my PhD studying band structure of high-tc superconductors (experimentalist, ARPES). These Cu d-d interactions right at the fermi energy give me huge hope. Feels very familiar to other superconductors (re: all the cuprates). (Note: I specifically worked in a lab that was measuring a lot of the d-wave character / gap-energies of various superconductors) All in all, I'm now much more bullish on LK-99 being real su…

I think we're being trolled. Or trawled. Not sure which, yet. But the mention of Salvatore Cezar Pais in the patent should be enough to put this to bed for serious folks. https://news.ycombinator.com/item?id=36967333 In case you aren't familiar with the man's work, here are some highlights of his discoveries over the last decade: Conditional possibility of spacecraft propulsion at superluminal speeds High frequency g…

Lead solder is mostly ok. Arguably lead free solder has been much more damaging for the environment because of all the e-waste it created.
> lead free solder has been much more damaging for the environment because of all the e-waste it created. We're getting quite off-topic here (I guess I should have used different examples), but I would be interested where you got that information from. Most consumer electronics devices do not break prematurely, and especially not due to soldering issues. Source: I buy most electronics second-hand, I regularly repair…
One of the theories at the time was that the poor thermal design of these devices (the most notable example being the Xbox 360) lead to cracks in the solder balls after repeated thermal cycling.
