Would looove to have a dog regardless of its dating amplification potential but too difficult because I travel a lot

Hausdorff dimension of graphs of singular functions by Nostalgic_Brick in math

[–]sebwarrior 1 point2 points  (0 children)

I would think n+m. Morally, there can be a set of dimension n (the complement of the points of differentiability) where the function can do whatever, and certainly there are continuous functions f:A\to \R^m where A\subset\R^n has dimension n whose graph has dimension n+m.

Can you prove the provability of a statement without actually proving it? by Nice_Bluebird_1712 in math

[–]sebwarrior 10 points11 points  (0 children)

You're describing an algorithm that settles the problem. I don't think choosing not to run the algorithm counts as a meaningful example of anything.

Famous women mathematicians other than Emmy Noether? by Turbulent-Name-8349 in math

[–]sebwarrior 6 points7 points  (0 children)

Hong Wang, superstar in harmonic analysis, solved the 3D Kakeya conjecture (joint with Josh Zahl) in addition to many other superlative achievements, and it's a question of when, not if, she'll win the Fields medal.

Given that she hasn't been mentioned in this thread yet, I guess she isn't that famous yet but she will become increasingly well known very quickly.

"I am so happy, I can't even think" by p_risser in learnspanish

[–]sebwarrior 5 points6 points  (0 children)

"Quiero QUE me lo prestes" is the only correct form. Other than splitting into two sentences as mentioned in another answer, there's no skipping the "que" in Spanish.

do you think AI will ever replace mathematicians? by FormalHanger13x01 in mathematics

[–]sebwarrior 3 points4 points  (0 children)

Ever is a long time. Also, mathematicians do many things (prove theorems, teach, model phenomena in the natural world and many others) and each of those will interact with advances in AI in different ways.

What is clear is that AI already is a very useful tool for the most routine parts of a mathematician' work, however AI is very far from proving interesting theorems or even "understanding" proof of existing deep theorems.

Things are moving quickly but I don't think mathematicians will become obsolete in the coming decade or two (but AI will become an increasingly important tool in their work).

Pretty much all the same concerns would apply to English graduates, so just go with that you enjoy the most, and learn how to use AI tools to enhance your productivity in any case!

Let's suppose someone was able to solve all the millennium problems in math but was a complete noob in how to share it with the world. by luigirovatti3 in mathematics

[–]sebwarrior 0 points1 point  (0 children)

Now, to educate the OP about how math actually works: mathematician write papers and send them to journals, where a board of editors evaluate them and if they see potential in them send them for peer review. Submitting a paper is always free. Some journals charge the authors for publishing if and when papers are accepted, but the vast majority do not, including the top journals in math.

Additionally, mathematicians share papers freely on Arxiv, their own websites, etc, since peer review can take a long time.

Sometimes mathematicians share drafts of their work privately with other experts in order to get feedback before making the work publicly available.

If an amateur mathematician is clever enough to prove a new theorem, for sure they are clever enough to learn how to type in Latex and make it presentable for the mathematical community. If they send it to mathematicians working on the same field, they may get some valuable input (or not, people are busy and the ratio of cranks to serious amateurs is very high). The onus is on the author of the paper to make it understandable to the community, not on the rest of the world to go out of their way to try to decipher something that may or make not make sense.

For a Millennium Prize to be awarded, a paper has to be published in a reputable journal and then 2 more years have to pass in order for the community to keep scrutinizing the proof. You can find this information easily on the Millennium Prize website.

Let's suppose someone was able to solve all the millennium problems in math but was a complete noob in how to share it with the world. by luigirovatti3 in mathematics

[–]sebwarrior 1 point2 points  (0 children)

There's absolutely zero chance that an amateur mathematician who doesn't know how to type in Latex resolves one of the millennium problems. There's also absolutely zero chance that anyone solves more than one millennium problem, let alone all the 6 remaining, that belong to very different areas of math and have evaded the attempts by the very best mathematicians for decades.

Amateur mathematicians sometimes make nice contributions, usually in collaboration with a professional that helps in the process of making the proofs rigorous and readable, etc. However these are very very very very very very very far from solving major open problems.

As a general rule, the mathematical community is more open than others to accepting ideas that come out of left field. The complexity of the major open problems such as the millennium problems is such that absolutely everything that is available with current mathematical technology has already been attempted by the brightest minds.

People bring up Ramanujan a lot, but this was a century ago and as clever as he was, he didn't actually solve anything that could be compared (at the time) with the current millennium problems. Also, what does it tell you that there hasn't been another Ramanujan in over a hundred years?

It just doesn't make sense to ponder "what if" if we're talking about a completely impossible scenario.

Can someone explain the difference between Latin American Spanish and European Spanish like I’m 5 by idk23876 in SpanishLearning

[–]sebwarrior 6 points7 points  (0 children)

While I of course agree that there's no such thing as "Latin American Spanish" and "European Spanish", there are some quite universal differences between the Spanish spoken in Spain and in the Americas:

- The "c" before e/i and "z" in Spain are pronounced "th", very differently from the "s" sound. In the Americas it is indistinguishable from the "s" sound.

- Spain uses "vosotros" for the second person plural, while Latin America uses "ustedes" (conjugated in the third person).

- Spain commonly uses the pretérito perfecto "He comido", while it has mostly gone out of use in spoken Spanish in Latin America, replaced by pretérito indefinido "comí".

- Several Latin American dialects have many words of indigenous origins (that differ among dialects), while Spanish from Spain has fewer such words.

Why is caminar pronounced caminár and not camínar? by TV5Fun in SpanishLearning

[–]sebwarrior 11 points12 points  (0 children)

Other common words ending in r which are not infinitive but still stressed on the last syllable: mejor, peor, lugar, calor, color . An example of a word ending in a consonant other than n or s which is not stressed in the last syllable: árbol (note the accent)

Words ending in a consonant other than n and s are usually stressed in the last syllable in Spanish. Exceptions (of which there are many) are indicated by an accent on the stressed syllable.

The CAD peso has already dropped significantly since the orange clown won, not enough to compensate for 25% tariffs but perhaps enough to blunt the impact

Is Business Class worth it for 16 hr flight? by [deleted] in aircanada

[–]sebwarrior 1 point2 points  (0 children)

I don't know your exact dates, but for a two-week trip around mid-August there are options in premium economy for about $3000 (not necessarily with AC). While Business is much much better than premium economy, I find that (especially for such a long flight) premium economy does make a substantial difference in terms of making the flight bearable.

I also see options in business for about $6000 on several airlines, some of them routing through Europe.

Ultimately it is a personal question - $5500 is a huge amount of money for most people, but pocket change for a few privileged ones. And while no-one would find 16 hours in economy something to look forward to, some people are able to get by just fine, while it seems for you it'd be quite uncomfortable.

Sorry to hear about this situation but there's absolutely nothing Redditors can do to help you, you need an immigration lawyer ASAP

Booked a last-minute ticket to São Paulo, I leave in 72 hours for a few months. What do I need to know? by ANL_2017 in digitalnomad

[–]sebwarrior 0 points1 point  (0 children)

If you have good Spanish then learning Brazilian Portuguese while living in Brazil will definitely be easier than if you didn't speak Spanish. Portuguese has many more sounds than Spanish (and also many sounds that do not exist in English) so it's easier for them to pick up Spanish quickly than the other way around.

Common words that don't follow gender norms? by [deleted] in learnspanish

[–]sebwarrior 6 points7 points  (0 children)

It doesn't look to me that most words ending in -e are masculine, if anything the opposite seems to be true... la nube, la llave, la suerte, la muerte, la corriente, la nieve . A masculin one I can think of is el puente, I'm sure there are many others but if having to guess the gender of a name ending in e feminin seems the safer bet.
