Is there even the slightest chance that at some point in history a white woman got knotted by a dire wolf
>>16893511Given when and where they lived the answer is definitely no.
if i have a scientific theory that i want to publish can i do it while being just a normal guy?where to publish for people to carehow to check if something like my idea has already been publishedhow to format the thing i want to publish- any guides on thatetc.
>>16893860You can. Anyone can submit to arxiv though you would have to follow the strict latex guidelines - https://info.arxiv.org/help/submit_tex.html - downloading existing papers or templates would be a good starting point.For checking already published articles try using Google Scholar.

Quote from Wikipedia: "Under string theory, strings are bundles of energy vibrating in complex ways in both the three familiar dimensions of space as well as in extra dimensions."Simple question: is this a symptom of schizophrenia?
>>16893204Is there any point in doing problems you can't check the answers for?
what's the best approach to learning AI/ML/DL in 2026? Should I do freecodecamp, codeacademy or Deeplearning.ai specialisations?
>>16894074No, but your question might be.
>>16894074So, basically, harmonic oscillators with extra steps? It seems more like a lack of imagination than schizophrenia (imagination led astray)https://arxiv.org/pdf/2407.06856
2/3 of the perimeter of the pentagon is visible. Is that too much? That's a rhetorical question.
>>16894278Harmonic oscillations happen in something. String, gas or field. What the hell are "bundles of energy" and what's their vibration means? It's nonsense. If an equation looks like vibrations that doesn't mean you should postulate vibrations.
>>16894302Things like the wiki quote are just dumbed down pop-sci answers, not detailed scientific explanations. If you want the latter go look elsewhere.> Harmonic oscillations happen in somethingIn the theory "strings" are fundamental, in the same way you are taught in high school particles like electrons are thought to be. The energy strings have then comes from their modes of vibration just like any vibration you are familiar with has energy.
>>16894302The point is, harmonic oscillations are a related physical phenomenon but harmonic oscillators are a formalism. Even if unispired, looking for new applications of the same old formalism may be naive but it is not schizophrenic. Your complaint seems to be about the word salad coming from taking said formalism at face value. >>16894366It seems that this is no different from the "luminiferous aether" word salad of 19th century electromagnetism
>>16894372The aether wasn't a terrible idea, it was actually good science. Until then every type of wave scientists had encountered required a medium. When the newly discovered electromagnetism turned out to be a bunch of wave equations it wasn't a stupid assumption to believe there also had to be some unseen medium they moved in - the aether. It took breaking that mindset, and some experiments, to advance physics.String theory has many problems, it could very well be wrong, but it's very different to how the concept of the aether arose.
>>16894409>String theory has many problems, it could very well be wrong, but it's very different to how the concept of the aether arose.The analogy with aether is not about string thery as whole, but about said dumbed down pop-sci talk of "bundles of energy vibrating", because something has to be vibrating, right? Just like every wave needs a medium. Even better, let's throw in a semantically overloaded word like "energy".
>>16894438Actually vibration and energy are the most scientifically accurate and precise words in the whole description. Their use is no different to that of QM or QFT.
>>16894366Thanks for the answer.>just like any vibration you are familiar with has energyThe vibration I'm familiar with has constant or dissipating energy, energy is not the thing that vibrates, that's why it's frustrating. I'm bachelor in biomech.Electrons... they feel kinda fundamental because they match fundamental math idea of a point. Even if electron somehow consists of other particles, they better to be points. There's nothing less than a point.
>>16894806Unfortunately, even if points make the math simple and and easy, they can't physically be true. If electrons really were zero-volume points they would have infinite mass and charge densities. That's simply not possible.
What is the purpose of the Neutrino? It travels at the sped of light, but there are claims it has mass which cannot be true if it travels at c. Or, is the rest mass so small it can actually travel at c? Is it just excess energy and not actually a particle?
>>16895250Our best understanding is that neutrinos have a very very tiny but nonzero mass, and that they "travel at c" simply because we have no detector sensitive enough to pick up on the difference.
>>16895250The neutrino masses as so small that they 'effectively' travel at the speed of light (but NOT at c). The difference is so tiny that a neutrino coming from another galaxy millions of light-years away would only be delayed compared to a photon by a few seconds, if that.
>>16895263>"travel at c">>16895323>'effectively' travel at the speed of lightIf time slows as velocity approaches c, from the nuetrino's perspective how does it have time to interact with anything since it essentially is emitted and travels across the universe instantly?
>>16893204Why doesn't science acknowledge the biological reality of race when there are numerous genetic distinctions/adaptations that every race has?How many more distinctions need to exist before they recognize that we are clearly not all the same?
>>16895851>Why doesn't science acknowledge the biological reality of raceRace, and species, but politics has overridden science and deformed it to not hurt people's feelings. How do you tell the retarded race they are a subspecies?
>>16895843Interactions are about position, not time. They aren't affected by time dilation. However scattering cross sections are dependant on energy and that dependency can be complicated, so in that regard the likelihood of a particular interaction does depend on kinetic energy (velocity).
