> smoking is not an appropriate analogy at least insofar

Missing the forest for the trees.

The point isn’t that neglecting to mask is exactly the same as smoking. Obviously these are different. The point is that in both cases the person in question is advising one thing and doing another. The fact that a doctor smokes or doesn’t mask up in a pandemic does not mean that their advice to not smoke or to wear a mask is not good advice.

If a person regularly snacks on lead paint but tells you not to eat paint, the advice is still good even if it’s coming from an idiot.

> it is not ad-hominem to try to understand a person's motivations

Sure, but claims of hypocrisy are still not a rebuttal.

No doubt it was hypocritical for Dr Mike to tell others to social distance and then hop on a boat with a dozen people unmasked, just as it was hypocritical for Gavin Newsom to attend a dinner at The French Laundry while telling others to stay home.

This isn’t actually relevant to whether the advice to socially distance was sound, though.

The idiom is, "Do as I say, not as I do."

Yet here you are trying to convince folks why this doesn't lead to poor morals, low self-awareness, and a lack of trust in doctors. We are talking about a doctor, of course, not just an average nobody. And we are talking about a doctor with 6 million subscribers. His influence is wide.

Last I checked, a doctor is not the same as a politician.

I have been treated by very good doctors that smoke.

And also... https://en.wikipedia.org/wiki/Ad_hominem

kafkaesque · a day ago
I'm not sure why you are drawing a parallel to a good doctor that smokes.

I never said "Doctor Mike" is a bad doctor. I have no idea if he is a good or bad doctor.

Further, an ad hominem is when a person attacks someone's character without any base.

I wrote specifically about him not being at the forefront and questioning his values, as displayed by his actions during the pandemic. His actions were literally not in line with Covid guidelines. Those are guidelines that were formulated by hundreds (thousands?) of doctors, all of whom sought to be at the forefront of medical science during a pandemic.

As another user said, MRI scans not corresponding to brain activity is not really news, and in at least the part of the US I live in, MRI scans are not so easily recommended, especially since they're not covered by health insurance.

Dr. Amen should be called out, of course, but it doesn't mean a doctor is at the forefront for doing so.

I came to the US for college from Asia to study physics (and mathematics). I actually came to study astronomy because I found it fascinating but didn't really like physics or math. My first physics encounter in college here transformed my life. There was no memorization. Instead, we had short quizzes in each class (first 5 min), weekly individual assignments, weekly group assignments (two students each), four "midterms" where one could get densely written "cheat-sheets" as well as weekly physics lab that often went on far beyond the time slot.

In high school, physics was mostly based on memorization. There were a few problems but all based on some patterns. None made you think extremely hard.

I also found that many American students (who were extremely good in my experience) seemed to have a much better practical sense.

One of the key steps in the development of a physicist is the transition from solving textbook problems to creating your own problems. In essence, the skill one learns in graduate school is defining/crafting problems that are solvable and interesting. The primordial phase starts in college as one is solving many problems. Initially, the new problems are straightforward extensions of existing ones (e.g. add an air resistance term for parabolic motion). Eventually, one (hopefully) develops good taste and essentially is doing research.

Interestingly, I also find very different attitudes to physics in the west (at least in the US) and other parts of the world. In US universities, physics is still seen in glowing terms. In many other places, physics is what you study if you couldn't do engineering. Young people (well, all people) are impressionable and this subtle bias affects what kind of students end up studying the subject.

> physics is what you study if you couldn't do engineering

This reminded me of something from my alma mater.

At my (Canadian) university, there was a running joke that engineering was what you studied if you couldn't get into computer science. In fact, the Engineering and Computer Science faculties would semi-frequently prank each other because they were next to each other, I guess. Each faculty focuses on different things, of course, but the "running joke" was that engineering courses were just easier, not as rigorous, and therefore getting in engineering was seen as easier (and so they had more time to do such elaborate pranks).

Again, I don't think this had any truth to it, but it was just one part of a fun tradition the university had.

Also, this was a long time ago. I'm not sure what the current state of this is now or if it even still exists.

> "Learn how to avoid peak traffic hours." Most people living in Bangkok cannot do this

you can absolutely do this. Once you learn how to live there and design your own routes with motorbike taxis, sky train etc you do save a lot of time. It's still quite bad but it's 20 minutes vs 2 hours sort of better.

Every time I tried taking a motorbike taxi, they charged me probably three times more than a local to just travel maybe 1km, not to mention Bangkok has one of the deadliest roads in the world, if not the deadliest. I have explored pretty much all of Bangkok and I don't think the MRT and BTS are as convenient as some people make it out to be. It is built as it is in any other city where it's very concentrated around the city centre but anything right outside of that is terrible.

Also, for two weeks in December you have the Red Cross festival. I challenge you to schedule your day every single day to avoid that mass of hell if you live anywhere in a 2km radius of that. Even if you call a tuktuk or a motorbike, they will absolutely NOT come to get you if they think there's too much traffic, or worse, they will tell you to get off somewhere where it's convenient for them.

Like a lot of foreigners, you seem to have built your life avoiding many things in Bangkok, which you can do in any city, but that's not the point. You are compensating for how poorly the city is built and how poorly the city is ran. A city is not appealing if you have to self-impose so many restrictions and find so many workarounds.

I'd take Bangkok over Singapore any time of the day/month/year. There's still a bit of chaos in Bangkok in 2025 but once you spend a few days there and learn how to avoid peak traffic hours and areas it's incredibly charming and charistmatic city with loads of activities and opportunities for all classes of people. Singapore while clean is incredibly dull and characterless unless you're a billionaire.

"Learn how to avoid peak traffic hours." Most people living in Bangkok cannot do this. Also, a very high percent of the time, the Icon Siam area is extremely congested (even on weekends). Yes, you can avoid living in or going to that area, but there are also very few nice areas in Bangkok in general.

Most don't have the luxury of the flexibility to avoid certain areas and/or certain peak travel times (which in BKK are many throughout the day)

Am I the only one who sees "content boxes"/divs with content displayed in different widths as poor design? At least in the example given, I would think you would want the image and its associated content box to be the same size for all four and not have its content vary in width based on how much content it has.

But in terms of functionality, I'm sure there are plenty applications for this!

Is it possible to label/tag these submissions as containing content that is AI-generated? I think the HN community would appreciate that
