Bypassing the CUDA moat is, in fact, one of the major tasks Deepseek set for itself. Their efforts in this area are likely one of the main reasons for their slow release cadence, culminating in their v4 inference setup that runs on Huawei A

That wouldn't explain why Deepseek is fast relative to other Chinese providers, especially considering that they're reportedly ahead of the curve among Chinese companies in moving off Nvidia. I think their quant fund background ha

Had they wanted a good ML relevant physics Nobel, the committee had decades to award a prize to Marshall and Arianna Rosenbluth for the Markov Chain Monte Carlo method. Would have been self-evidently important and relevant to both physics a

Reducing the levels of allergens in food very likely has the side effect of promoting food allergies in children, due to lack of exposure during development. That's a strong negative consequence.

Not sure how this is "dishing it out and not taking it". They intend to "take it"; they will force Bytedance not to sell, and thereby lose its US business with no compensation.

I am old enough to remember US internet companies spamming users to support net neutrality, even those who aren't American and can't do anything about it. And net neutrality was heck of a lot less of an existential issue for them.

Beijing has a veto on the sale, and are likely to exercise it. From their point of view, allowing the US to force a Chinese company to sell itself off as soon as it achieves success would set a very bad precedent, and encourage a torrent of

The trouble with doing that for Freakonomics is that the work on abortions reducing crime, which has been proven wrong, is the first chapter and the centerpiece of the book. It's the thing that they use to exemplify the "freakonom

I mean, Plato argued for governance by philosopher-kings, not too different from the Confucian conception of governance. What's more interesting to me is the skeptical attitude toward omens and the notion of heavenly will. That sounds

The desktop client is basically a web app, little different from running it in the browser. As for the app, I have been pretty unimpressed by it; performance is sluggish, and emails are displayed poorly (lots of unreadably small fonts with

From Fig. 2, it looks like the "hazard ratio" is minimized at a total cholesterol level of around 230 mg/dL, with both higher and lower total cholesterol levels associated with higher mortality. However, medical advice (see

It stands to reason that someone who can create his own file system can't possibly be guilty of murder.

That German lab should sell LK-99 crystals. I wouldn't mind buying a souvenir for this whole episode!

No, they were not careful about their claims. Putting aside the drama around the arxiv postings, they had previously explicitly made the "discovered a room temperature ambient pressure superconductor" claim in a Korean language jo

I'd add that the 3-4 preprints that put the final nails in the coffin for LK-99 --- the ones that showed how ferromagnetic samples produce half-levitation, pointed out the Cu2S structural phase transition, explaining why the flat bands

Yes, I noticed that this article disproportionately quoted American scientists who played relatively minor roles in the replication efforts. I guess the reporter just found it more convenient to reach out to them for comments.
19.
by seewhydee 3y ago
The thing is that there are now multiple independent lines of investigation pointing to LK-99 not being a superconductor, and explaining away the original "smoking guns" offered by the authors. It's like we have a murder susp

The video really rubbed me the wrong way. I guess it's a persona he's putting on for the YouTube channel, but that "tough minded skeptic" bit is way over the top. He spent all his time criticizing various problems with t

by seewhydee 3y ago
Yeah. I would argue that he displayed some bad science of his own. He kept harping on about how the LK-99 paper didn't show resistivity going down to exactly zero, but had a residual resistivity. But that is exactly what you would have

Yeah, it needs to be doped with a room temperature superconductor, lol.

> According to some of the new data, the resistivity of LK-99 increases as you lower the temperature, like some sort of anti-superconductor. The writer based this on a sarcastic tweet, taking it at face value. It seems to imply that resi

I would argue that CMTC is acting here more like a twitter drama queen than a proper scientist.

That's a pretty condescending take on what's evidently a paintakingly put-together theoretical+experimental study, from one of the best condensed matter groups in the world. Believe it or not, researchers more than any other peopl

Contrary to the linked tweet, there's some reason to think its diagmagnetism is pretty interesting. It might be the second most diamagnetic non-superconductive material known. Why this may happen may keep condensed matter physicists en

The team believes they have made the world's first room temperature superconductor, and they submit the paper to APL Materials (Impact Factor 6.6)?

Yes, there exist diamagnetism-paramagnetism phase transitions.

A room temperature superconductor would, by definition, maintain quantum coherence (of the superconducting order parameter) at room temperature.
