I wish this kind of disclaimer would have been in my physics book in school. Big reason why I didn’t pursue an academic career in physics is because all the quantum stuff sounded like a religion, trying to convince itself that superpositions are real and you can’t measure things, because you just can’t.
Many years later I know that there’s explanations for these things and that some of the illogical things I’ve been told were not nearly as certain or just flatout wrong. Because yeah, we’re still pushing the boundaries of our understanding outwards…
I’ve taken like four or five advanced trigonometry courses and I still can’t really define what trigonometry is. Mathematics is like Andrew Tate’s Hustler University scam. If you take one class, it only exists to prove that you’re a mark and sell you more classes.
I enjoyed the trigonometry unit in my highschool geometry class, but that’s because it was mostly proofs, and those were just philosophy about triangles.
For some reason people seem to think they’re fundamentally smarter than people were back then.
Yeah, you may have technically had a better education, but you’re not inherently more intelligent than the average person back then, and a genius from that time is still miles ahead of you.
Yeah, it’s been linked to systemic racist thought patterns (which are often unintentional but should be acknowledged). I explain it to people like this: take a handful of sand and turn your fist so that your palm faces perpendicular to the ground. Now release the sand slowly… What shape does it form? It isn’t rocket science.
Pyramids = basic engineering shape for a sturdy structure. Wide base, tapered top. A lot of early monumental structures were constructed with that basic concept in mind.
The constant barrage of Joe Rogan clips of idiots claming it was impossible to move these huge stones over those distances with the tech at the time was what drove me to disable YouTube shorts.
Honestly, the first and arguably most important step is recognizing how much of online content is specifically designed to get a reaction out of you, primarily in the form pissing you off.
What’s funny (I guess funny lol) is ever since I got my current job about 2.5 years ago, I no longer need to use social media. I am much, much happier without it. But I still get into little fights on forums and I really wish I didn’t. Every now and then I resolve to be less hostile, and things really do improve, but somehow I always get dragged back into old habits. But I’m a little hesitant to completely abandon things like Kbin because they are often my only window into events/what is going on/my hobbies. Idk what the answer is.
Well, the fact that you have the self awareness to realize is a great place to be. Not sure what to say other than try to treat your body with respect and your mind will follow.
I honestly I’m surprised how much of a problem this is for people. All I’ve done is made sure to hit the “not interested” type buttons on YouTube and tiktok whenever they pop up, and I’ve run into next to nothing after like 3 times of doing that. Sometimes I’ll watch something the algorithm thinks is adjacent to ragebait or alt-right bullshit so it’ll try to feed it to me, and after not-interested’ing the video it goes back to feeding me the stuff I actually want…
Do people just not use those features or is my experience with the algorithms really that different?
This is the truth. I am a few months away from getting my PhD in particle physics and the core questions being raised in all levels of the field at the edges of our decent big-picture understanding are so exciting.
It is interesting, but it feels like there are too many compromises made at the expense of observational data.
The first issue is the reliance on a ~2eV neutrino to compensate. While sterile neutrinos could theoretically be that massive, we have yet to find conclusive evidence of steriles and don't know the absolute masses or the mass ordering of the neutrinos mass eigenstates we have observed. (I am in neutrinos, so this is the point I am most familiar with.) While the discovery of steriles could occur, my buddy works on a search for eV scale sterile neutrinos and all of his findings have shown that there is no preference for any sterile signal at or around 1-100eV. Normal neutrinos also can't work: While we don't know the masses of each neutrino mass eigenstate individually, we know the sum of the neutrino masses, ~0.06-0.1eV, eliminating normal neutrinos from contention as well. This is a core failing, as it relies on the presence of an equally unproven particle as DM, but isn't as good a fit as DM in many ways, leading into point 2...
It has a hard time fitting to galactic cluster data. The Bullet cluster is one of the best observational proofs of DM, and MOND doean't offer a good explanation for what we see. It also doesn't account for gravitational lensing, which is a problem given we can see that quite clearly. Since it is only effective at huge scales and can't be easily checked in a lab, it needs to at least consistently describe observations before I can consider it over DM, which does an excellent job of describing observation. This leads into my final point...
There isn't really any way to experimentally verify/refute it. I am an experimentalist, and while not every theory needs to have a labrotory confirmation, it seems like there is no way to falsify MOND. DM experiments have long proposed models that allow for some DM particle interaction mechanism, however infrequent, with barionic matter that would confirm/deny those models. While far from exhaustive, it at least allows for the ruling out of certain models if the expected flux isn't there. MOND seems opaque to even this sort of experimental checking.
There are other issue too, but I am not well versed in GR, which is where many other tensions exist. Overall, it seems like an interesting math problem, but I can't take it seriously until it gives us something to test or describes what we see much more accurately.
