[@snarzetax]

The fundamental flaw in the article is that it directly states that annihilations are explosions. To be precise, they are not the same thing. Annihilations expel photons(no mass) and are simply a flash of light. Explosions are a sudden expansion using waves of kinetic force to push everything away from an epicenter(creating motion, thrust). If we could harness gamma photons, annihilations would be an awesome source of power but, they would still not be a source of motion. Also, Jenna has retracted her position on vaccines but that part of the story gets no press so very few people know.

I love that the pinto/Indy car analogy is literally just to explain what the word "faster" means.

@@Hailfire08 The mindboggling thing to me is that people are willingly consuming bad information that they know they don't entirely trust because it takes on the semblance of what they would expect in that situation. The perfect example are those google dropdowns and answer boxes at the top of your search--those are all entirely scraped and answered by websites whose provenance and reliability are taken as given because they're at the top of the SEO or most closely match the phrase one inputs. People would rather go through multiple of those dropdowns to get an answer that they think satisfies their needs rather than do the due diligence and eventually save themselves some time.

[@differentbutsimilar7893]

@@manwalrus The good news about those drop downs is that with the commercialization, they have become increasingly less useful and relevant. I am trained to skip them at this point, because they fail me every time I try to use them. Can't be a unique experience. I don't need advanced knowledge to know the dropdown didn't remotely understand what I was searching for. People learned to rely on them because at one point they were at least good enough for conversation. Nowadays, they're good for nothing and that alone will probably deter reliance somewhat. You can't even convince yourself the answers mean anything when it becomes obvious it's still struggling to understand the question. It answers every question but the one you're actually seeking an answer for, until it is about something you're buying.

When I was in middle school I wrote travel articles for places I had never visited in order to save up spending money for a vacation I was going to take one summer. Don't know what websites they went up on as everything was anonymous and disconnected. I also wrote comments for song from some online music streaming site. Those weren't technically fraudulent I guess because they let us listen to 10 seconds before we wrote our review. I want to clarify, the website that I was writing travel articles for knew that I had not visited the places, there were instructions and procedures to follow for how to look stuff up. This type of low effort content has existed for the better part of 20+ years online, but AI is increasing the rate at which it can be pumped out. I literally would not be surprised if an actual kid wrote the article in the video.

[@gingerestkitten]

It’s really just a disclaimer. Think back to university when you were doing Composition as one of your reqs and they forced you to write everything in a program that had a little owl as the icon (I forget what it was now). It gave you a score - you needed to get it to 90 “quality” and fix all your Chicago or AP style guide errors. Or like.. if you’ve ever written something for “inclusive language” for HR while doing recruiting they sometimes make you write it in a web app and get the same kind of score. Thats all AI now. Yara opened the article, the AI scored it for SEO and readability, Yara hit Publish and it automatically tagged them as an author is the most likely explanation. The “may have been generated by an AI” is boilerplate like “sent from an iPhone” being on your emails, and UNTRUSTED SENDER gets put at the top of every email you receive from outside your org. That brings up an interesting point though that you actually trusted the disclaimer at the bottom of the article as factual..

Not *exactly* topical, but this reminded me of my high school chemistry class. We had to do a huge end of year project with each student getting a unique prompt for an experiment. My prompt was stupid hard, requiring me to bust out the dictionary and thesaurus just to understand the single sentence I was given. Eventually got the grasp of it and after research saw it was pretty cool; required me to build my own barometer. Was doing my final write-up after having done the experiment, felt unsure about one thing I was about to write so did one more google search. Found a university article that COMPLETELY countered everything I understood about the assignment. Like, negated each element verbatim. Lost my mind for a couple days before finally realizing that there was a clause in the opening paragraph of that article that could be interpreted as saying "written below is a counter example," but like the specific diction was such that I originally took it as "here's an example." Sudden peace followed by UNYIELDING RAGE were my prevailing emotions. Got an A. Moral of the story: fuck that author. Nobody I showed the article to properly understood it on the first go.

[@OzgurNevres]

Regarding achieving the top position on Google: In the early days of Google, it was relatively easy to manipulate the algorithm, especially when there wasn't much content available on a particular topic. Once you secured the top spot, you could acquire numerous links from other websites. However, today, manipulating the algorithm is not as straightforward. Nevertheless, if your content held the top position, let's say, 20 years ago, it implies that you have accumulated thousands of links to that article from other websites. Links continue to be one of the most significant factors in the Google algorithm, if not the most significant one. If the article was recently written, it might not be at the top spot. But, thanks to its historical links, the Google algorithm still regards it as an 'authoritative' article. This is how such content maintains its first-place ranking.

[@davidjkemper]

Thanks for providing this explanation.

[@hunterm9]

In addition; Google will grab the date currently on the website. So even if an article was written 20 years ago and unchanged, if they updated the date it will change on Google. So many (clickbait/scummy) websites will have a script that automatically updates the dates on their articles in order to attempt to provide more "credibility" to them. So not only are some of these websites still legacy top rankers, but they may look recent to the average observer. Just another reason why multiple sources and critical thinking is important when doing any research on the internet.

[@monkeydetonation]

I really hate that feeling of confusion reading an article like that. I always go into a spiral of thinking "Am I stupid? Am I going insane? Is this evidence of cognitive decline?

Honestly, even the Star Trek writers seem a little confused about the distinction between the warp drive and its antimatter power source, but that's neither here nor there.

[@DrewLSsix]

From day one star treks warp drive has been a loose magic fast travel system with the word SCIENCE slapped on it. Someone asked a nerd what's a plausible way to go FTL and the nerd said "well theoretically there's what's called spacetime warping but..." producer: PERFECT! WARP DRIVE IT IS!! But what kind of gas would it run on? Nerd: well, the most energy dense power source might be what's called antimatter, but.... Producer: right! Antimatter, it powers every no matter what. No concept of what warp drive would actually be, how it would work or what it's effects might be. No thought given to how much antimatter would be required at any plausible level. I did some napkin math years ago and found that the energy required to get the four and a half million ton Enterprise up to full impulse speed and back is equal to roughly 7,000 tons of antimatter, plus it's equivalent in regular matter. That's assuming 100% efficiency, and canonically this is done with a few fusion reactors rather than antimatter reactions. I gave up trying to calculate how much fusion fuel that would require as it started to look like something close to the whole mass of the ship itself. And the order to full impulse is given so casually you just know Picard doesn't have to pay the bill!

Something that a lot of non-teachers don't realise is that a huge number of American high schools are just diploma mills. Before the pandemic even, but especially since the pandemic, administrations have adjusted the role to be more like daycare than education. Students are enabled to not learn anything with no consequences, natural or otherwise. I've worked in high schools where more than half of students in all classes just sit on their phones, where daily attendance is 50% of kids on any given day. I also currently work in a school where there are consequences, and despite serving a very low economic area, even the low performing students are learning at about an expected level in my class. But a lot of kids go to college because it's "the next step" in life when they really only have a C level elementary or middle school education.

Something in their narrative style that I think would translate well is after they finish the video they have an aside where it's something they realized while writing the video and it's a tangent, but also interesting and so they add it in. And I think it would be very interesting if you did something similar (also it boosts engagement bc it's like a post credits scene to get people to watch til the end, everyone wave hi to the omnipotent youtube algorithm, hiiiii, pleasedontsmiteme)

This made me want to learn about antimatter engines, and I ended up reading the wikipedia entry on antimatter rockets. That site has managed to hold on to a level of rigor that's become almost non-existent for the most part anywhere else. But it seems like a herculean effort, and it seems like that web site could fly apart at any time, just as soon as all the volatile components present in the rest of the internet combine in just the right way.

This reminds me of an issue that pissed me off at work a couple days ago: I had a niche question about some Microsoft product, and as I usually do in that situations, I went to a search engine to see what forums and help pages had on the topic. One page I clicked on had the exact question I had in the title. The body then included in information on how to resolve that issue. Scrolled back to the top to see if I missed something, and I saw a banner proclaiming the article had been written with AI. These niche forums and help pages are incredibly important to me, and I hate seeing them get cluttered out and replaced by useless garbage, that likely is plagarising from the actually useful work other people did. I really hope enough people push back against this, still unclear to me the most effective way to do that though.

[@MarianneExJohnson]

When I was in college -- and I was studying engineering, for what it's worth -- I had the distinct impression that there were professors there who were more interested in making the students feel stupid than in helping them get smarter. Not all professors, to be sure, but disturbingly many, particularly in the first two years. I suspect that they rationalized that behavior as "weeding out the ones who aren't cut out for it" or something, but I feel very strongly that this kind of approach to teaching causes a lot of good students to drop out, and a lot of bad students (who just happen to be good at memorizing the textbook) to stay and then perpetuate this bad culture. Or write bad popular science articles.

[@JorenVaes]

I can't say you are wrong because I don't know your situation or professors, but during my PhD in engineering, and getting my hands dirty teaching, what I noticed is that a lot of professors are genuinely super excited to be able to share their field and really want to take students with them to discover and learn. The problem is, instead, that doing it for 20 years has made them lose touch with what a young bachelor or masters student actually knows and understands, and how this stuff that is easy for them (as they have been doing it for 20 years!) is really not as easy as they think. As a result, they go 'but look at the mathematical beauty' because they have honed the ability to think in pure mathematics for 20 years, and don't understand students can not grasp the topic without the link to real world examples as they do not (yet) poses the tools to do so. Which kinda makes it even more tragic, because they really want to share and teach, but without a good support system to give them feedback on the shortcomings and help them relate to the position of the student, they fail to do so.

[@inevespace]

@@JorenVaes it looks like more absence of teaching skills. Your explanation would work for prof. who just started to teach after long period of working, only in this case they can be detached from knowledge of students. But people who teach for few years clearly see what concepts are difficult for students. And after few years of experimentation with explanations they can find the way that majority will understand it. Problem usually that you immediately find that you need to explain things beyond your topic. You maybe teaching some engineering topic, but you have to jump into explanation of some mathematical concepts(quite deeply), when you find that students didn't understand it from other math courses.

It's a common practice, unfortunately, to pump out shallow content and continuously "update" it to trick people and search engines into thinking it's timely. The most egregious examples are the "Everything we know about [upcoming game/movie]" articles that are constantly "updated" to say that we still don't know anything new. Usually they will generate their own slop (now with an AI, of course), but I suppose buying a website with lots of existing content works just as well.

I think an element of what you call scientific literacy is philosophy. I never studied philosophy as a kid, but when I studied for the Law School Admissions Test (LSAT), I had to learn about the structure of valid and sound arguments. Your example person who was ignorant of antimatter physics, but otherwise scientifically literate, recognized the key missing step as the article giving no link between why antimatter explosions would be so large, and why that would make you go fast. I think learning about necessary and sufficient conditions, various common logical fallacies, and what is needed to make an argument sound and valid could go a long way to helping people develop the skills for detecting nonsense.

[@SpecialEDy]

Well, matter and antimatter mutually annihilate into pure energy. But, the problem is converting that energy into useful work. I suppose that youd want to inject the antimatter and matter into a "combustion"(Reaction?) chamber with a matter rich ratio. Then the extra matter would become superheated and used to propel the spacecraft. Hydrogen would be the fastest exhaust velocity, and itd be the best material as fuel to react wwith Hydrogen. All current engine designes use exhaust gas as the reaction mass, be it chemical rockets, nuclear designs, or ion thrusters. In all designs, you heat or accelerate the gas molecules. Or, I suppose you could just just use the photons released by the reaction to propel the spacecraft? But, Im not sure if youd need some kind of strong magnetic field to bounce the photons off of? that also wouldnt be very efficient.

[@sobertillnoon]

I think the pinto was named after the horse, not the bean. So I just looked it up. Apparently pinto is just the Spanish word for modeled color or something like that. So the bean and the horse are named with just a description. The car was named because horses are fast and cars are fast. This is the third edit.

[@stevenjacobs2750]

Yeah pinto is basically mottled or painted. So a pinto horse is a horse that looks painted. A pinto bean, similar. The car was named after the horse, even though the car didn't have a funky paint job, they just exploded.

As someone who grew up in a family with one, I can assure it was named after the bean.

My guess at antimatter engines? Two types: - antimatter decay engine: notable in using a large, thin film of radioactive material that produces positrons or anti-protons. Doesn’t NEED to emit antimatter, but perhaps there are advantages to be had. Notable for the velocity of the emitted mass being used for thrust. - antimatter heat engine: uses antimatter annhilation to produce heat, which in turn is used to produce thrust
