This introduction must assume that the reader already understands physics deeply, right? For instance, the page on Hamiltonian mechanics stated that force is the derivative of momentum with respect to time. I can't imagine how one will

I was wondering how the manufacturers address the potential culture conflicts. Obama's documentary American Factory revealed two notable contentions. One is that American workers think that the management is too tough on them while the

Luckily those kids won’t go far academically. I can understand why one needs tutoring for IIT’s JEE, but SAT? Students in Asia and Eastern Europe send their LOLs. So kids who have certain talent can beat those who need tutoring for SAT one

Is this a US thing because there has been so much debate on race, equity and etc? I thought this was obvious. Academic excellence arguably requires the least resources, which means the difference in social-economic status matters the leas

I think there's a substantial difference between "Hey ChatGPT, could you explain Maxwell's Equations" and reading Jackson's textbook and solving the problem sets on the book.

I buy the author's point that we should minimize the time on tactical knowledge, but the following particular point seems over generalized: > The school model focuses on just in case knowledge. Take my math education, for instance,

I don't understand the rant either. Tan already has a platform. If he wants to "hurt" someone, wouldn't cold facts and logic work the best? What's the point of ranting some nonsense?

I remember Stephen Wolfram mentioned that he managed Mathematica Products via email since it was founded in 1988. I was wondering how he could that so effectively.

I agree with you that one needs dedicated study. I just don’t think Anki card is necessary — it’s great if it works for you, of course. The repetition comes from tons of reading, writing, and listening, and speaking, all intense and dedicat

It's common in the IT industry for a non-technical person to become the lead. For instance, Andre Jassy built AWS from ground up. I was wondering if teams in aerodynamics can have the same dynamics.

Maybe, but at least it is not immediately clear to me why scrapscript is better than SQL. The homepage of scrascript says: > Scrapscript is best understood through a few perspectives: > “it’s JSON with types and functions

The same reason I don't like AWS' Step Functions. The spec in JSON is horrible. On the other hand, Step Functions is pretty scalable and reliable and can take practically unlimited throughput. It's a good story for how a prod

An often-heard benefit for using YAML is that JSON does not have comment. What I don't understand is why we would switch to a whole new language. Just add a filter before loading the configuration, which can't be harder than switc

I can't remember how many times I heard or saw the argument "but that is in YAML", which implies that the configuration(or god forbid, the code) is simple and well designed. I find it hilarious. And a worst contender is embed

Yeah, possibly. I have only visibility to the teams I worked with. That's partly why product market fit is hard to find, as it relies heavily on intuition. I'd be happy if I'm wrong.

Ah, I guess this is the curse of ignorance: I saw the sentence but didn't register its significance as I'm not familiar with what's required in game development.

I think Google's situation is due to its promotion culture. As Hasting of Netflix said, culture is all about who gets rewarded and who punished. When so many people got promoted for so-called impact and complexity yet their project ult

Yeah, I'm neutral on the merits of different promotion philosophies. On the personal level, I'd prefer promotion on mastery because it gives an IC leverage: Jeff Dean can still code out a brand new system to solve an seemingly imp

I like how they promote engineers based on "mastery". This is very different from Google, who treats promotion as a tool. That is, mastery often is not the only consideration. Sometimes it is not even a consideration. Of course, n
