For those interested in a kind of retrospective about 40 years after Feynman's speech, read "Physics in Latin America Comes of Age" (published in 2000) by José Luis Morán‐López:
> At the end of the 20th century, a large “science gap” still exists between Latin America and the developed countries of the North.
> The description is not intended to be a complete analysis, but may give a sense of the significant development that has occurred in the past half century and of what might be needed to make the 21st century a flourishing epoch for science in Latin America .
> The most developed group includes Brazil, Mexico, and Argentina, which have, respectively, about 3000, 2200, and 2000 PhDs involved in physics research.
Feynman, of course, always had confidence in the ability of the people of Latin America to do good physics. In fact his mentor Manuel Sandoval Vallarta was born in Mexico and emigrated to the US to study at MIT. Emigration to the US or Europe is typical of successful physicists from Latin America, including Juan Maldacena, a theorist from Argentina who discovered the AdS/CFT correspondence and has been a professor at the Institute for Advanced Study since 2001.
Anecdotally, I think Europe has more opportunities these days. My friend Gustavo, a high energy theorist from Brazil, got his PhD in the US but now works at the Oskar Klein Centre for Cosmo Particle Physics (OKC) in Stockholm.
Documents written in the 1980s in LaTeX still compile and look great today. Good luck doing that with an old MS Word file, especially if it has equations in it.
> And I found a fascinating pattern: the AI gives artificially high scores to reports written with AI [...] it was giving very high marks to poorly reasoned, error-filled work simply because it was elegantly written. Too elegantly... Clearly written with ChatGPT.
This is an interesting phenomenon, but I would have liked to see some quantitative evidence for this N=24 sample, e.g. would a paper ordinarily get an 80% score but the LLM gives it a 95%?
I also wonder how accurate a professor's perception of style is. I tend to write in a formal style, even in online forums like this one, and I wonder if people assume I use LLMs as a result (I don't).
Zstd decompresses faster, perhaps 2x faster, but Brotli is fast enough. Often a little faster than gzip/deflate.
Brotli can compress more because of context modeling, about 5% more without the static dictionary and even more with it. Brotli works better with very short data.
Brotli is a bit more streamable than zstd, i.e., hides less data during transfer.
Zstd has better encoder implementations, but basically there is no technical difference in the demands of the format on the encoding algorithms. Compression could be equally fast, Zstd just saw more love and specialization for encoding. As a result, Zstd libs are 2x heavier than Brotli.
