how do we distinguish science from non-science???

Anonymous Sat 02 Apr 16:51:29 2022 No.14358228 View Reply Original Report

Quoted By:

What logical, methodological, and mathematical features distinguish science from other academic disciplines, from pseudo-science, and from flat out disinformation?

If we want to promote science and factual public discourse, how should we restrict or limit the spread of pseudoscience and misinformation, and what logical and methodological criteria should we use to determine what should not be censored? What makes something settled science?

If you want replicability to be a criteria for censorship you'd have to defund the research of those fields except for very high sample and more simple projects that can actually hope to draw conclusions. The closest thing done in psychology is probably the study of mental illnesses in drug trials bc they have the resources and profit motive of not wanting to f up and get sued and trying to actually get their drugs cleared. Kind of the same with sociology, but there it's mostly a reluctance to accept things that perpetuate unflattering stereotypes as being actual phenomena that have some real effect on relative standings of groups in the populace. The topics were mostly pseudo in their infancy and based in prejudices, but it wasn't entirely fallacious or bigoted as some people sought to understand these things to rectify them like classifying forms of mental handicaps and at least exploring if they were diseases or traits. Otherwise understanding the traits which differentiate a better and a worse are in the interest of a system of justice that doesn't include anything about group distinctions in it's scope. Things like should this child get an advanced or a remedial course of study? Is it reasonable to expect this child to learn to read and write this subject? Is it reasonable to expect a person to attain employment? Is it reasonable to complain about insert group difference here?

Science should never have been democratized. If scientists could create tests based on observable phenomena to knock each other out of the profession and sharing scientific information as being settled or concrete or even releasing accurate statistics were thoughtfully hampered we'd have much more logical leadership and public discourse. It's not so much gatekeeping as trial by fire that's needed.

Ok sci, why does this?
I imagine two character with screen as a head, just flat plane or like LCD. So, when imagining these, which is more chad and which is more virgin? As I see it, the widescreen one must be chad, the other way around doesn't work. The square itself seems to have some quality of being more sidekick like.
This isn't about head shape, I don't know what exactly it tracks to, since imagining people with similar shaped heads of triangle or rectangle doesn't really seem to cause the same. But as abstract form, the head being literally a concept of a screen like an LCD, for some reason 16:9 just seems chad. Yea? No?

One of the best conceptual definitions of p-value such as the ASA uses is as follows: “The probability under a specified statistical model that a statistical summary of the data (eg, the sample mean difference between the 2 compared groups) would be equal to or more extreme than its observed value.”(6).

It’s a field which has a lot of practical problems on the theory and applied side. The two most important problems are efficient error correction and producing longer coherence times and higher temperatures, which are theory aligned and applied physics aligned respectively, but both questions have elements of both (actual logical vs. physical qubit abstraction on the machine level, optimal pulses and lattice alignment are both good examples of crossover).
There’s a lot of work to be done, but researchers from all angles have a lot of good methods to attack these problems. Progress has been very brisk.

>possible
In principle yes, there's nothing in our fundamental understanding of physics stopping them from existing. But we might also be missing some fundamental understanding to begin with. This is why experimental physics efforts to build a QC is interesting, even from a purely academic standpoint.
>extremely beneficial
Maybe, in extremely niche applications. "Extremely beneficial" is a huge overstatement.
>we've been trying since the 70s
No, the idea of a QC wasn't even conceived of until the mid 80s, and there was little to no interest in it until Shor's algorithm in the mid 90s. One could argue that quantum information theory got started in the 70s by Holevo, but he wasn't thinking anything about doing computations or algorithms with the notion.
>we're still not very close to actually doing it
As far as anything practical goes, that's right. Fault-tolerant QCing is decades away at best. But noisy quantum devices with 50-100 qubits exist now, and they are interesting to study as physical systems themselves - modestly sized, controllable quantum systems with lots of "unwanted" interactions with a classical environment.

Quoted By:

https://aip.scitation.org/doi/10.1063/5.0087175

>The mass–energy–information equivalence principle proposed in 2019 and the information content of the observable matter in the universe estimated in 2021 represent two important conjectures, called the information conjectures. Combining information theory and physical principles of thermodynamics, these theoretical proposals made specific predictions about the mass of information as well as the most probable information content per elementary particle. Here, we propose an experimental protocol that allows for empirical verification of the information conjectures by confirming the predicted information content of elementary particles. The experiment involves a matter–antimatter annihilation process. When an electron–positron annihilates, in addition to the two 511 keV gamma photons resulting from the conversion of their rest masses into energy, we predict that two additional low energy photons should be detected, resulting from their information content erasure. At room temperature, a positron–electron annihilation should produce two ?50 µm wavelength infrared photons due to the information erasure. This experiment could, therefore, confirm both information conjectures and the existence of information as the fifth state of matter in the universe

Why not just openly publish a list of what we're not allowed to discuss, would save ppl the trouble of making all the content that was just deleted?

Twitter explained it best when they said [We can't tell you the rules because you might comply with them]. They want excuses to silence you. If they publish a set of clear rules, you might abide by them and then they have to either tolerate your existence or go against their own rules. Almost all platforms now use this system so they can shape the discussion to be whatever they want it to be.
