If one works in a field where there is already an issue of abundance, which is (nowadays) basically any field that produce information, it's better for the society to produce less, but higher quality, more meaningful work. Of course, i

I buy the argument that work arrangements can significantly shape psychology. I am really annoyed by the culture to "sell" your findings using grandiose phrasing. It's a observation that confirms many people's prior, but

Interest and competence is a feedback loop that drive each other. I really had it with the reductionist views that "don't force kids to learn things they don't like" and "keep up the practice and the rest will come&

This looks like the result of an abuse of the foreign students visa as work visas, partly due to leftover pandemic era policy. In a typical government response, instead of actually fixing the loophole, they use the blunt weapon of cutting v

What I learned as a parent and from interacting with other parents is that most parenting advises are useless because it's what "works for their kid". Most parent's style is coevolved with their kid through lots of try-a

Speaking as a researcher, I think the whole citation business was invented by and consumed by administrators. Researchers don't need citation numbers to discover new works and evaluate people. They are perfectly fine asking their circl

Citation numbers doesn't provide any useful information for a serious researcher. It's all a game for administrators.

The study does not prove causality: it is right in the title of the paper: Association Between Slow-Wave Sleep Loss and Incident Dementia. Sorry for the rant: we should not share university press release articles, they are always clickbai

I am wondering if there's any performance comparison between js based approach like mathjax and katex with the built-in mathml rendering? Given that the the browser needs to parse and render the generated html and css for the js approa

It seems to me that the authors of the paper, in anticipation that writing scientifically (that they don't believe the lab leak hypothesis, but it cannot be disproven) will be misinterpreted by journalists and the public, resorted to

I think "learn B because it will help you do A better" type of advice often doesn't work. But "learn adjacent fields if they are interesting to you, time and energy permitting" may work, as they sometimes do yield u

Actually I think all the things that happened up to now is probably a net positive. However there seems to be a trend that the closer the technology is related to human communication, the less obvious it's a positive. It's probabl

A lot of technology disruptions happen by a "bait and switch" approach. A new technology appear that promises to produce something at a much higher efficiency and much lower cost. Only after it already took over the market did peo

It's a really nice idea. I wouldn't call it a proof in the rigorous sense, because you need to define trigonometric functions first and be careful you don't use Pythagorean theorem to avoid circular logic. It's however p

I don't understand why people at Microsoft's gaming division are not acting like their hair is on fire right now. The only reason I and many people stay on Windows is because of games. The success of Steam Deck makes Linux a major

It's truly remarkable that most likely SVB lobbied congress to allow more risk taking because it will encourages innovation, while in reality what it did destroys innovation.

With how the system is supposed to work, isn't anyone who have uninsured deposits supposed to buy their own insurance? If the risk of bank failure is low, then the insurance premium should be very low. If the premium is high, that&#x27

I think this is not the right way to look at it. You can think of mathematical proofs as computer program that is compiled by the mathematician by hand. There is a lot of room for error, but with practice and peer review, it's relative

Computer assisted proof is not a new idea. The most famous example is the four color theorem, which (as far as I know) does not have a humanly understandable proof. For this particular proof, it looks like the computer assisted part would b

I personally think media reports of most academic results is a distraction. Experts would surely start to weigh in very soon if this result is as significant as claimed. It doesn't hurt to wait a bit before discussing it. As the story

We shouldn't encourage this type of reporting of academic results. A better headline: "Evidence towards causal relations between mental health issues and Facebook use for some College students in 2004". If this doesn't l

There's nothing wrong with presenting existing knowledge in the most organized, clear, and accessible way. Historical context is useful, but I don't think we need to spend a lot of time explaining the initial confusions. When you
