I was reading an article about a proposed abortion ban that is poorly draft to cover any procedure that causes "harm" to various internal organs, which could potentially cover many types of chemotherapy and surgery: https://www.theguardian.com/us-news/2025/feb/02/wyoming-republicans-anti-abortion-billThis go me thinking, should the Hippocratic Oath really be "Above all, do not inflict harm that is not reasonably calculated to provide better patient outcomes than the natural history of the untreated disease."?It seems to me like taking the Oath too literally has the same problems as this proposed law. Thoughts?

Anon, which book do you recommend for starting to learn quantum physics?
AI where are you?
>>16567668Quantum physics is a meme that doesn't exist. There's quantum mechanics to explain what happens but until the old guard dies off and we get a reformulation of everything as it currently stands we won't be explain why which is the actual physics bit.
>>16567668Griffith's QM (You may skip this and start with Shankar's)Shankar's QMSakurai's QM
>>16574419this is how idiocracy starts btw
>>16567668Simple you dont learn it. Because it has no use case other than a predictive measurement of economic systems.Stick to linear algebra statistical theory non linear has correlations that only work with a good amount of data. Which the economic system has and its abstract in nature. You couldn't mesure a physical system with it.Which is what schrodingers cat proved. And he gave up on it

How does the interplay between quantum chromodynamics (QCD) confinement, vacuum energy fluctuations, and the holographic principle contribute to the emergence of spacetime geometry in the context of a non-perturbative formulation of quantum gravity?
First off, QCD vacuum structure isn't just "there"—confinement means gluonic flux tubes dynamically form, effectively generating a mass gap. This already suggests an emergent geometric picture at strong coupling. Now throw in vacuum fluctuations, which are Lorentz-invariant but get renormalized to hell, meaning whatever “spacetime” emerges has to encode that fine-tuning nonlocally.Holography tells us the bulk metric isn't fundamental—it’s just entanglement structure in a lower-dimensional QFT. AdS/CFT gives a handle on this, but lmao, real-world de Sitter? Still coping. So, best bet? Some non-perturbative QCD-like sector (maybe large N gauge theory) backreacting on a holographic bulk, where confinement sets the IR cutoff and effectively generates spacetime curvature.Gravity isn’t a force—it’s a collective effect of entanglement, and confinement plays into that by setting up the “stiffness” of the vacuum. The real question: does QCD itself holographically encode our spacetime, or is it just an example of the deeper bulk/boundary duality at play? If you can bridge that gap without breaking locality or unitarity, congrats, you just solved quantum gravity.>tl;dr spacetime is emergent, confinement is a boundary condition, and non-perturbative vacuum effects are doing more work than they get credit for.

Would quantum computing still have practical value if it were proven that P = BQP, meaning classical computers could efficiently simulate quantum computations?
>>16576666Quantum computers are literally "the cool" they are advancing cryogenic tech, so I'd like them to stay.
>>16576666Yes. If you build a pdp cluster and are ok with them processing at 1/10,000th the speed and a bunch of floating point rounding errors are acceptable.
Im looking to get into CVD of aluminum, does this look like a reasonable price/is it suitable for my pruposes? 650$ is kinda crazy for a glorified tube, but I don't see a lot of other options that have the conflat flanges ill prolly need.
>>16575804If there isn't a ghetto diy high-vac tutorial on yt, this might be the best you'll get$650 for a specialized piece of kit that size doesn't sound too bad
>>16576169I've seen some glass bell setups aren't those good enough?https://youtu.be/5X0EKbpLuRc
>>16576175The key word here is "high vaccuum," which is a specific range of pressures. Look up how to test whether it's in this regime, and if bell jars are known for being able to reach it.
>>16576184A bell jar might be able to handle it depending on what it's sitting on. In the vid he has it sitting on a metal plate, which should be able to achieve high vacuum if you use the right grease. The trouble comes if you need to bake it out. It would be tougher to put heating tape all over it and it might crack the glass if it heats unevenly or something.
>>16576533The other question is whether you need just high vaccuum (i.e. lightbulbs, vaccuum tubes), or an ultra-high vaccuum, which is what that thing in the OP is probably built for.Also I don't think bake-out is necessary for just HV, afaik
We should send probes to Alpha Centauri and other nearby star systems soon. Is this technically feasible with today's technology? Even if it takes a long time to get there, say thousands of years to make the over four lightyear journey, they would eventually get there and could send back information about these other star systems and their planets and moons. Perhaps one or more star systems will be found to be enough like Earth to be habitable. What's stopping this from happening now??
>>16576004you need 4.2% speed of light to make it to Alpha Centauri in 100 years.
>>16572903>send signal to alpha centauri probe>retire>next guy working at the agency reads the response>can't make sense of it
>>16576100I mean we humans used to take hundreds of years to build cathedrals and shit.

Literally and genuinely, why is space cold if the sun is out there?
>>16574168Space is cold where the sun isn't. If you're in the sun you get cooked. If you're in the shade you cool off because of the endless black void.
>>16574168https://en.wikipedia.org/wiki/Boltzmann_constantparticles are not excited by heat -> particles are cold
The earth traps heat in the atmosphere and there is heat radiating from our core. Both of those things contribute to the temperature we experience along with the sun.
>>16574168When the sun is shining on you, space isn't cold. In fact, since there is no air to convect the heat away, you would get pretty hot if you were near Earth's orbit.
>>16574174This. There's no particles to transfer the energy. In the sun. When directly facing the sun, the International Space Station (ISS) can reach temperatures as high as 250 degrees Fahrenheit (121 degrees Celsius) on its sun-facing side, while the side facing away from the sun can plummet to -250 degrees Fahrenheit (-157 degrees Celsius).
As a demonstration, here is the results of the following prompt from various LLMs. It is recommended that the reader experiment with it to see the results.>Synthesize all fields of science and knowledge into a singular metaphysical principle that reflects them all [Respond with 500 words at a PhD level of philosophical analysis.]GPT 4oFull reply: https://chatgpt.com/share/676ede8e-6d2c-8013-aa72-61c1b9083151>At the core of this principle is the idea that all phenomena arise relationally. Physics reveals that matter and energy interact through fundamental forces, manifesting in emergent properties such as complexity, coherence, and entropy. Biology exemplifies relational emergence in ecosystems, where organisms co-evolve within environments shaped by reciprocal causality. Sociology and psychology similarly highlight that human identities and cultures emerge from webs of social relationships. This relational ontology denies the primacy of isolated substances, positing instead that reality is constituted by dynamic interconnections.>...Central to this synthesis is the metaphysics of becoming. Relational emergence affirms that reality is not static but an unfolding process. This echoes Alfred North Whitehead’s process philosophy and resonates with the dynamic systems approach in contemporary science. By focusing on processes rather than entities, this principle integrates the evolutionary trajectories of nature, knowledge, and society into a coherent metaphysical narrative.Claude 3.5Full reply: https://pastebin.com/SpgmngiR>The pursuit of a unified metaphysical principle that synthesizes all scientific and empirical knowledge leads us to consider what I'll call the "principle of dynamic emergence" - the notion that reality fundamentally consists of patterns of information that manifest through increasingly complex layers of organization and meaning.
neat

How do I learn math as someone who has always been a complete mathematical retard?Ive always invested all my time into learning the humanities and social sciences and barely any into the natural sciences. I barely survived high school math classes and don’t have any particular love for the subject if I’m being honest but I need to score well on my countries aptitude tests to get into the uni I want. I’m willing to put in blood sweat and tears to get good at it I just need to know the best resources to begin with.
>>16573561I’ll bring my hazmat suit>>16573568Alright that seems sensible. Where should I find these problems? I’ve hear khan academy is decent but someone told me that I shouldn’t use it because “it will only teach me to solve problems without understanding them”
>>16573573For your purposes you don't need to understand them. You just want to get a good grade on a test, so just get good at solving the problems by practicing them. Khan has a bunch of problems. Traditional textbooks are good too.
>>16573581Well yes I want to get good grades on the test but also do genuinely want to become good at math as I think it’s inevitable I’ll have to have to develop some decent compression (or at least something above barely passing high school maths) at some point regardless.Text books sound good, any good high school level ones you’d recommend.
>>16573588If you want to understand math, then use a textbook and follow the derivations and explanations closely before working on problems. I would need to know what level of math you're at and what you need to learn or get better at, e g. Algebra, calculus, whatever.
>>16573540do the following>buy a MATLAB home license for $149>read the math books in the sticky>solve project euler problems with matlab>do the olympiad practice exercises>do the SAT math practice>do the GRE math practiceafter this you will have learned more math than the average person and undergrad
How do I, with no relevant credentials, write a paper that is somewhat critical of a paper written by an academic working in industry (Cited by 878)? There have already been some criticisms, but they were missing the bigger point. Should I email the author? The paper is 2 years old. I'd like to write something proper that can at least get me published on Arxiv.

>>16573510Would it be inappropriate to message him on LinkedIn?
>>16573505>Should I email the author?why are you so high inhib that you haven't already done this, if you're a /sci/entist, you're interested in the truth, not a trophy that you can publish on arxiv.
Im looking for the true equation to estimate the flue-gas flow-rate induced by the draft of a smokestack.

If I took a bottle of still water, flow it through a sieve, boils it to 150°C, evaporate it then make the steam go through a condenser, will the water be safe to drink?
>>16575386>boils it to 150°CWhat?
>>16576543Thanks for the bump cretin. Not like you add anything to add.
>>16575387Yes. Just forcing it through charcoal is enough. Realistically, just distilling it e.g. evaporating it into another container, even osmosis is going to make it safe to drink. Millions of ways to skin a cat. Look into reverse osmosis. You could also just boil it...assuming there isn't any chemicals or dirt in it, it will still kill parasites, bacteria and virals.
>>16575386Sure. That's called distillation buddy
>>16575386you dont have a condenser
