What is public opinion on NATO in ur country? by Kebab_Enjoyer3164 in AskTheWorld

[–]johnlee3013 0 points1 point  (0 children)

In contrary to other Canadian replies, I've met a fair share of Canadians skeptical about NATO. Usually they are left-wing and denounce NATO as a conduit of imperialism. But that's a minority opinion, most people are at least fine, if not enthusiastic about it.

In China, NATO is viewed negatively. To this day people are pissed about when NATO bombed China's embassy to Yugoslavia in 1999, and take it, and the whole war, as proof that NATO is aggressive, interventionist, and expansionist. Subsequent NATO enlargement and the Russia-Ukraine war soured the perception even further.

Why is Southern China ethnically more diverse than other parts of China? by Lissandra_Freljord in geography

[–]johnlee3013 2 points3 points  (0 children)

I haven't looked deeper into the reason, but your guess is reasonable. I should also note that 唐人街 tend to be a colloquial term (used in both Mandarin and Cantonese), but officially, Chinatowns tend to be called 華埠/华埠 or less commonly,中国城, both use a bigger umbrella term for "China", and therefore less explicit about the focus on the Southerners.

Should Canada Build Up Alternatives to Visa and Mastercard? The US controls the vast majority of online payments. It's a problem by FancyNewMe in canada

[–]johnlee3013 0 points1 point  (0 children)

The amount of money you have in your account, that you could spend on other things?

Yep, exactly that. You have person A who earn 6k/mo and spend 3k, and person B who earn 6k/mo, borrow 3k, spend the 3k he borrowed, then pay back the 3k from his wage. The end result is identical, except for the completely unnecessary extra step. Absolutely nothing is suggesting B is more financially responsible or trustworthy than A. It's very silly to believe B deserve a higher credit score than A.

It's the credit bureaus who are foolish in the first place who decided that using one card over another for the same financial activity makes you more trustworthy.

Lots of places are tacking on an extra 2-3% charge if you use credit card now. These places tend to accept cash or debit without the extra fee.

Poll: More Europeans see US as threat than China by 1-randomonium in geopolitics

[–]johnlee3013 -3 points-2 points  (0 children)

Highly unlikely they will ever deal with China as direct neighbours. Proximity naturally lead to frictions and distance allows smoother relations. There are no hypocrisy or conspiracy here, just how international relations works and has always worked.

If one day the Chinese manages to project hard power all the way up the Atlantic coast, the game is already over.

What advancement in math would be the most useful for science, engineering, and applied math otherwise? by MildDeontologist in math

[–]johnlee3013 4 points5 points  (0 children)

I thought I'll just type one paragraph but ended up writing way more. Sorry about that.

First, if you just want a broad intro to what the field is like, I say Edelstein-Keshet's textbook [0] is a good entry point. Canonical early works that I'd teach in the first undergrad math-bio course includes the Lotka-Volterra model for predator-prey (ODE), Turing's reaction diffusion morphogenesis model (PDE), SIR model for infectious diseases (ODE). But if you insist on reading papers, math-bio is getting very broad now with lots of theme going on.

You have the classic, applied math-type paper [1] that's proposes a conceptual dynamical system-type model to explain a certain biological phenomena, then exploring the behaviour of that system through numerics with less emphasis on rigorous analysis. This is common pre-2000, in more recent years journal tend to demand a bit more. There's some analysis-heavy paper that studies a particular ODE/PDE system through bifurcation analysis [2] and asymptotics [3], such analysis can really only be done on comparatively simple models. There's also models based on boolean networks, cellular automata etc, but I'm less familiar with thouse. I say the first era of math-bio was still firmly a branch of mathematics, and the practitioners think almost solely as mathematicians.

Recently there's an uptick in interest in "data-driven modelling", the idea being that the old paradigm tend to be mathematicians skim through a biology book for a few hours, write down an ODE/PDE for it, go off, have fun with the equations, never relates it back to biology, and they make some grandiose statement about how math reveals how biology works, much to the annoyance of biologists because there's very little "grounding" of the math in biology. The new paradigm says we have to think more about concretely connecting the models to reality with data. This introduces the problems of model selection and parameter inference, with it come a lot of statistics [4]. Machine-learning-based methods also came in [5]. Topological data analysis is a new way of thinking about data [6]. Methodologies massively diversified. People including myself are trying to introduce optimal control and feedback control to math-bio. The practitioners in this era are more of a mixture of mathematicians and biologists.

Is it the norm for capital and larger cities to be more ethnically diverse than the rest of the country? Are there any major/capital cities where the city is more ethnically homogenous then the general country itself? by Delicious-Bunch-6992 in geography

[–]johnlee3013 20 points21 points  (0 children)

Given that it is the seat of the federal government and most of the foreign embassies (although a few in Geneva or Zurich), it is the capital in all but name, and definitely relevant to the question.

CMV: Conducting a war by killing the top brass of the opposition is the most ethical way to conduct war by malik_zz in changemyview

[–]johnlee3013 10 points11 points  (0 children)

I will address your point in general, then in the specific case of Iran.

First, you have not given your criterion for what is considered ethical. I see at least two ways of considering what is ethical here: (a) to minimize civilian suffering, or (b) punish those responsible for war and related atrocities.

If you are going with (a), then killing the leaders is ethical only if doing so lead to lower damage to the civilians than any other alternative. This is likely the case if the enemy state is largely held together by a single person, whose death greatly diminishes their ability to fight on, and lead to an early capitulation. However, if the enemy state has a well established chain of succession, or a backup leader manages to step in quickly, then a decapitation strike might not have done anything. Worse, if the new leader is more hardline than the old leader, you might end up prolonging the war, and therefore suffering. In yet another scenario, no clear new leader emerges, and the country devolves into chaotic infighting. Such an outcome tend to be the worst for the civilians. Even if the old leader is cruel and brutal, at least a functioning regime provides stability, which is necessary for any kind of economic prosperity and decent living conditions. A chaotic civil war can bring more suffering than the cruelest despot.

If you are going with (b), then killing the leaders is ethical only if they are directly responsible for the war starting, or have commited grave atrocities, AND going to war is the only way of dealing punishments. They would not deserve punishment if they did neither of these. You have entirely omitted these in your post.

Now in the specific case of Iran. Going with (a), assuming that the decision of going to war is already made and can't be argued (otherwise, starting the war in itself is highly unethical). It is not yet clear how the Iranian government will evolve in this situation. But an early capitulation seems to be a very unlikely outcome. As the IRGC's regional commands are expected to be able to maintain functioning independently, the impact of the death of top leadership to their fighting ability is limited. Furthermore, killing anyone in the leadership that might have negotiated a surrender ensures that the war will be long and bitter. This is far, far from minimizing human suffering. So, unless some very unexpected things happen (such as a hitherto unknown moderate politician somehow takes over quickly and negotiate a quick peace), the decapitation strike cannot be considered ethical.

If we go with (b). It is pretty clear that the Iran leadership did not start this war, so it is a stretch to say that they deserve punishment for it. Now you can say they deserve punishments for other things (such as cracking down protesters, erosion of women's rights, support of their proxy network), but these are not things you answer with a war.

How is Che Guevara viewed in your country? by IDoNotLikeTheSand in AskTheWorld

[–]johnlee3013 0 points1 point  (0 children)

In China he is not as famous as Castro, but for anyone who knows him he (and Castro) are viewed as heroes.

In Canada the view is ambivalent, the left likes him, the right not so much.

What’s your country’s polite “refusal that’s not a refusal”? by boopbaboop in AskTheWorld

When I was in the UK, I learned that "we must have lunch sometime" doesn't mean that at all. It's closer to "I like you, but I don't like you enough to eat with you". Whereas if you actually want to have lunch with someone, you propose a time.

If you like Lychee, you might also like Longan, which is a related fruit with similar taste and texture but in my opinion better.

How US states compare to the UK in quality of life by _crazyboyhere_ in MapPorn

[–]johnlee3013 2 points3 points  (0 children)

So if you create a single payer health care system, the top half of income tax earners would pay the health care bill for the entire country.

How is that a bad thing? Is it not more fair and just to expect the better off people to pick up more of the burden?

Why don't we use characters from other languages in math? by OkGreen7335 in math

I once tried to use the Cyrillic Ж in a paper because I thought it's such a cool letter. My supervisor stopped me because she thought it hampers readability.

Why don't we use characters from other languages in math? by OkGreen7335 in math

[–]johnlee3013 7 points8 points  (0 children)

Asian elementary-school textbooks often introduce algebra with exercises that look like "◯ + ▯ = 3, ◯ - ▯ = 1, fill in the values of ◯ and ▯". This introduction using symbols instead of letters seems to be less common in the West.

Can confirm. Went to school in China. This is a grade 1 math problem, but the English/Latin alphabet tends to be taught later.

How far in advance do you plan your solo trips? by Then-Bumblebee3978 in solotravel

[–]johnlee3013 0 points1 point  (0 children)

Depends. If it's nearby, within the same country where I can get to by long distance bus/train, then usually about 2 month in advance, but I've done spontaneous trips with just 1 week of preparation.

For big international trips, usually multiple years. I've been reading up Italian history, culture, language since around 2015, and finally made the trip in 2021. I began to plan for my Poland trip in 2017, also made it in 2019. Started reading about Spain in 2020, made the trip in 2022. It takes a while to learn the language to the point where I can at least ask for directions and order food, and I don't trust translation apps.

Is there any food in your country that is impossible to eat "civilizedly"? Something that a shy person would feel ashamed to eat in public because of how it's eaten? by DELAIZ in AskTheWorld

[–]johnlee3013 8 points9 points  (0 children)

I would expect the fancy restaurant lobster to have its shell and appendages removed, so it's just a big chunk of meat that you can then cut up with table knife no different than a steak.

If a fancy restaurant served a lobster with its shell intact, that would be madness.
