If you believe it there’s money to be made https://polymarket.com/event/is-the-room-temp-superconductor...

I've been wondering why the market didn't really respond to this. It dropped a lot on the previous articles where the Tc was around 110K, so I'm curious why it has stayed relatively flat here.

This is the only website I actually trust to give me an accurate picture of where we stand on LK-99.

As long as the blue line doesn't cross the red one, I won't believe in it. Money talks, bullshit walks.

> Good rigorous science takes time to produce. It can take anywhere between several months to a year or more, and the career implications for rushing something out that is later found lacking is not great. Implying that Chinese science is bad? Chinese universities absolutely dominate in chemistry: https://www.nature.com/nature-index/institution-outputs/gene... By my count, 18/20 top universities for chemistry researc…

I think for a lot of people this whole saga is probably the first time that they realize that a ton of original work is done in Asia, rather than that it is just our manufacturing hub. They have to adjust their mental model to account for a view of Asia that is in important ways outstripping the West in terms of resources and combined brain power. The amount of scientific output in Asia is astounding, and the number…

Well, most of HN still has the mentality that China can only copy/steal as perpetuated by the media.

It was true 20 years ago when China had to catch up in everything.

The thinking needs to be updated.

Heck, just look at chemistry publications from top US and European universities. Chances are, there's one or more Chinese names in most of them.

It would have been more convincing if you had given real past examples rather than speculative future ones :) Although I'm pretty sure there are plenty that many people can think of, so it doesn't really detract much from your point.

Auctions, sanitary towels, retirement, banking, disposable razor, sewing machine, canned food, interchangeable parts, antibiotics, solar cells, postage stamp, light bulb, pencil, air conditioning, insurance, dwarf wheat, spreadsheet, cold chain, double entry book-keeping, S-bend, infant formula, clocks, public key cryptography, passports, batteries, printing press, video games, GPS, contraceptive pill, shipping conta…

Looking at that list, I feel like we would first have to establish which things actually do make life better and which only make it more comfortable. This is going to be highly subjective.

For some reason, I'm not entirely willing to believe that my parents (who are still alive) had a less happy life than I have even though they didn't grow up with an iPhone. And it's not like modern conveniences have no downsides (e.g. increase in stress). That's not to say I would give up on these things readily, I'm just way too used to them.

I think probably most people could agree that treatments for diseases that regularly also affect young / middle-aged peolle are a good thing. It's hard to argue that someone in the prime of their life should die of some silly infection.

Exactly, the 99 stands for 1999, so potentially this material has existed for over 20 years and we could have started testing and replication on a much wider scale a decade ago. What benefit have we gained by disseminating this research so slowly?

What happened, for those who want to catch up: https://twitter.com/8teAPi/status/1685294623449874432 With the anti-hype hype that surrounds this discovery this was to be expected. Why would I disclose this kind of research to the public so that the whole world can benefit from it when I'm called a fraudster or a liar. Why would I risk my reputation – no matter how I spin my research – in a sacrificial circle jerk whe…

that account is fan fiction

Hasn’t this already been done by several groups? It’s the first paper but it’s old news now.

One somewhat ironic fact of this story is that the rogue former employee perhaps deserves some credit for bringing this thing out into the world. They had been working on this for quite a long time themselves, rightfully so. But now the whole world is working on it and exploring other methods and combinations of materials I would assume (to improve upon the original design and avoid any patents). How long would they…

I think there are multiple big reasons they didn't publish sooner. It is pretty clear that they were convinced, but had insufficient evidence to convince others. Additionally there had recently been a sensational fraud in their field so journals would have been extremely sceptical.

It seems to me they were just in the process of constructing a convincing paper, which included convincing tests and could have been acompanied by sending out samples to independent labs. Then they were essentially forced to put out what they had, which made their claims even more unconvincing.

For those experiencing this type of "black swan, but good" event for the first time, it is helpful to recognize that the human tendency to believe that all future "big events" will be dystopian downers, is statistically unsound. For a while I've kept a list of the things that could be "good" swan events, but to be fair I didn't have "room temperature superconductor on that list" :-) Other things that could happen: 1)…

I like the idea of this list. Some others: - Quantum supremacy - HIV vaccine - Synthetic life - Discovery of ET life - P vs NP solution

> P vs NP solution

If it's proven to be the case that P != NP, it would hardly change much on the grand scale of things as generally, that's what most people believe anyway. In particular, the world continues to function mostly in the same way (since, even if it was the case that P = NP, we haven't found any polynomial reductions yet, so we're effectively living in a P != NP world). Of course, for mathematics and CS, this would be huge, because the techniques used in a proof would likely be very interesting and novel.

If it's proven to be the case that P = NP, then it remains to be seen whether this knowledge can be turned into actually efficient algorithms (polynomial algorithms are not all efficient in practice). If that is the case, I think it might have more downsides than upsides, since all of cryptography would collapse.
