I don't think anyone's arguing that it's not okay to watch youtubers you like, but people are always going to be questioning you and your motives if you watch chud-lites or chuds.

Questioning viewing habits isn't a bad thing either, there's no reason that the background input we subject our noggins to shouldn't be subject to criticism.

It's just a shame he gets one little nit wrong, because Japanese has both stress/intonation and pitch accent.

Huh? AFAIK Japanese doesn't have stress in the sense of stress accent like in English and intonation is not relevant to what is being discussed.

Yeah, I was forgetting that there's a different between pitch accent (which Japanese has) and stress accent where pitch-accent is high/low and stress-accent is strong/weak.

There are commonalities between the two, though - because if someone asks a question in Japanese, there's the same rising intonation at the end as there would for a question asked in English.

Whats interesting is what it got wrong and how it got the questions wrong. It often starts out with the right concept and starts doing the math and then just veers off in the wrong direction and cant be convinced that its doing it wrong, in fact insisting upon obviously wrong facts to justify its answers (like insisting that 40 is larger than 63, very basic math stuff that is incorrect)

There is also a pretty interesting theory that things like ChatGPT may eventually become like Wikipedia. In the beginning everyone mostly intrinsically trusted wikipedia because it was this new and gigantic repository of information the likes of which we had never seen. Then we realized that it wasnt always right, and was fallible. Now we treat it as something of a starting point or a jumping off point, but we generally accept that it is not 100% correct 100% of the time and everyone knows that.

He posits that at least in the near term, ChatGPT may go the same way

It's almost as if algorithmically combined and controlled text processing models don't really understand the underlying concepts and have only been trained to seem confident, and that that in turn means it can be confidently wrong.

I have been watching a bunch of the 'History of the Universe' channel longform videos: https://www.youtube.com/@HistoryoftheUniverse

https://www.youtube.com/watch?v=_IkaetPoBZM

I can't say I have a full understanding of some of the stuff like the most recent 'Theory of Everything' vidoe, but at least I feel I don't understand it better.

https://www.youtube.com/watch?v=E4CsY5B3BoI

Oh great, more of these channels where they'll take vaguely science-related topics and use it as an excuse to speculate on all sorts of things that amount to little more than religion.

The first video has several instances of the argument from analogy fallacy whereby the analogy, for example when they're attempting to use doesn't satisfactorily explain the differences between an oblate spheroid and whether or not space-time is positively, negatively curved, or basically any other time they use any analogy to try and explain something which is, given our current understanding of the universe, impossible to prove.
And if we'd arrived at a theory of everything, I'm pretty loving sure a youtube channel wouldn't be the place for that news to be breaking, because that'd basically be a revolutionary discovery given the limits of our current understanding - so the answer to the second video is "no, period".

I don't understand why people are so loving obsessed about this, when there's so much stuff and things that can be evidentially and experimentally proven that one person can spend their entire life on it and still not make any amount of headway.
And if the point is to point out how little we understand, science already does a great job of this - because everything about the scientific method has shown that the more facts we have, the more questions we can ask.

A vid about GPT/language models.

TLDW: language models use tokens. Tokens are either common words or parts of words or individual characters. That way, rare words can be represented by characters, but common words/sentences take up less space. The choice of what words are tokens is simply based on how common those words were in the INITIAL data set.

There are some tokens that are really weird such as PsyNetMessage and SolidGoldMagikarp.
If you use those in a message, GPT-3 completely glitches out and returns nonsensical crap (not in ChatGPT, that has been patched since this was discovered).

Why? Well, what happened is PsyNetMessage is a term that appears very often in some game's debug log that somehow made it into the initial data set, and SolidGoldMagikarp is the name of a reddit user who was extremely active in r/counting... where people just count up numbers. Whatever web scraper they used for the initial dataset picked those up as really common.

Then, when they actually started training the model, the researchers cut out those weird terms and used more sensible data. However, the tokens already existed at that point. Result: the tokens exist but there's basically no information associated to them. The language model has no idea what they "mean" or how to respond to them. This causes the glitchy behaviour.

Along these lines:

this might be the right thread to ask
to any Physicists out there who understand relativity, space time and gravity:
this video calls out a bunch of other YouTube videos about the cause of gravity. I�m not sure I understand it all but is it correct?

https://youtu.be/PjT85AxTmI0

I�d really like to know

It's "fine" to say that other YouTube videos of understanding of gravity is lacking, because unless there's been a pretty radical change in the scientific community - which we would almost certainly have heard about, given the big impact it'd have had - it's pretty fair to say that nobody understands gravity.

We don't know how/if gravity propagates like the other fundamental forces, and we can't fully integrate it into our existing models.
Scientists ended up building the worlds largest beam cannon just to attempt to find this out at CERN, and so far we're still pretty much in the dark.

So really, while someone can make an rear end out of themselves by claiming other YouTubers don't understand it, that someone also doesn't understand it.

thanks for this, I�ll take a look for sure

this is what I thought� I (somewhat) understand the concept of action at a distance and how gravity doesn�t fit into any current unification theory.

I�ve read �In search of Schr�dinger�s Cat� and �the God Particle�, lol

recently I watched a couple of those other vids and was surprised they seemed able to explain it. their argument seems to boil down to: Gravity is caused by differing time dilation with respect to the observer

the video I linked says that�s not it, and fair enough.

I just thought maybe our understanding had changed and I hadn�t been notified in accordance with the physics phone tree we all agreed to

I was just pointing out that the YouTuber who posted the video also has no loving idea, despite the implications of the clickbait headline and scrapbook-looking preview image.
That he then goes on to handwave a bunch of explanations, which don't account for propagation and our inability to integrate gravity with the standard model of particle physics as well as how none of what he's talking relates to quantum mechanics, is just about par for the course.

I'm not sure about the best way to go about science education, but I'm sure taking a page out of tabloids is a good solution.

Symbolic Butt posted:

I gotta watch the video until the end but the way I see it is not about questioning youtubers' understanding of gravity, it's about questioning their fluency in applying the general relativity theory.

I think the idea of time difference creating some kinda torque that influences the space dimension is absolutely mind blowing. So wild that I'm inclined to believe it's just popscience people not understanding GR really.

But again, I'm not a physicist. I'll watch his argument more carefully.

If you wanna question fluency in terms of scientific understanding, you first gotta address all the lies to children that fill most peoples imaginations; the notion that atoms somehow look like solar systems, the definitions of acids and bases and how it relies on water being part of the solution (pun fully intended), and things of that nature.

Sure these things help in establishing a basis, but all too many people are stuck with these notions.
Even people who've been piled higher and deeper in a narrow subject, can harbor these lies to children in areas they're not expert in.

I'm absolutely for leaving the science education to the people who're qualified for the job; I realized a long time ago that I wasn't cut out for it.

The best thing about science is still that for all the answers we get, we get even more questions.

Nah, once the four years are over, you're now one of the worlds foremost experts in a field so narrow, unless you choose to work within that field, it's useless.

If you're lucky, you'll have learned critical thinking and other things along the way, but that's absolutely not a given as it typically isn't part of a curriculum.

It's low-key amusing that a video with a guy talking about saturation has audio that's all over the place.
Some segments are clearly recorded in post and set over B-roll, and it's pretty jarring.

this is why vinyl often sounds better because you can't mix as loud on vinyl

There's a real argument to be made that Phil Spectres use of instrument doubling and echo chambers, which was nominally done to make transistor radios and vinyl sound better, was the start of the loudness war.

At least one paper also makes the observation that it was already happening during the 60s' Motown era, and it also mentions that the term originates from 1979 (a little more than 30 years before it got popularized).

Intensity Modulated Radiation Therapy, which is done by heating up wolfram until it gives off electrons and accelerating them then shaping them into a beam, is used for cancer therapies and is supposedly around 2000mSv.
It's typically always listed as 2Gy/day, because the entire point of IMRT is that you can control the dose via beam forming and things like Bragg''s peak to only be maximized in the area where it'll do the most good.

In total, 30 days of IMRT will be 60Gy, which if received in the entire body in an instant, would be fatal within 24 hours.

Yup.

The way it works is that they have a beam-forming mesh on the end of the accelerator which is then spun around the patient, so that only the place where all the beams cross gets the full dose.
This area is calculated using a mix of PET-CT and MR scans, and are done by a medical professional with a specialty in particle physics using a computer.
