But the initutionists like Brouwer also seem to argue this way. And the late Wittgenstein, too.
So, "x is true" means the same as "there is a prove for x".
How could this asstertation be hold in the light of the discouveries of Kurt Gödel and Tarski and even Heisenberg?
We already know that there are certain true statements, which cannot be proven. Therefor, the equivation of "Truth" and "Evidence" cannot be hold.
Is intuitionism wrong?
Outdated teachers that could already be replaced with Youtube videos insist on DEI over merit no matter how much they know they are creating an incompetent workforce and I know exactly why. It is because fraud is everything these people are. They are fake humans and don’t even care a little bit about what is correct or incorrect. It’s only about conforming to the newest fad ideology, which is usually just verbal vomit. At what point do we stop trying to help them think critically and just force them to conform to the truth by manipulating and verbally abusing the shit of out them just as they do to us when they refuse to answer even a single fucking question honestly. We just let these faggots walk all over us, and they make it right to the top of all our schools and universities through intimidation. We are giant pussies when it comes to saying anything about race.
Realistically, can we develop a system using probability and statistics to predict their personalities? Where can I find statistical methods to apply to public figures based on the words they speak? Will we be able to use an AI on our phone to predict frauds and keep them out of STEM?
Any truth to this? Anyone else hear this argument?

How does this clueless whore have any reach at all?
I read about freeze desalination a while ago and I don't get why this isn't done at scale by transporting seawater to reservoirs in the mountains, storing it until winter and then freezing it at ambient temperature. Plus they could use excess solar energy during summer to transport it and then recover it during winter as hydroelectric power. And sell the salt, magnesium, lithium, ... byproducts.
Is this idea too retarded? How complex would something like this be?

We discuss research, DO NOT offer medical advice (just fucking go see your doctor), make fun of premeds and shitpost.
Keep vaccination/clamping/vitamin K/soliciting advice out of this thread and start your own because it takes a lot of space.
is it biological reasons or because of systemic reasons?
So my question is how do we square the old data with the new when the amount of change we're trying to avoid falls within that margin for error?
Genuinely asking. Research papers on it would be cool if you have it.
I've come to three conclusions for low cost lifting from the moon....
1. Mass driver/railgun/gauss-gun/etc powered by solar thermal power.
Can be great for shit that can be compacted into the launch barrel, not what im discussing.
2. Aluminium-Oxide solid rockets.
Considering this can be created from lunar regolith, solar thermal power, and maybe some re-usable chemicals, seems to be the best possible launch mechanism for huge/strangely-shaped parts.
3. Aluminium-oxide (powder/gas) RCS systems.
For obvious reasons, a solid rocket booster isn't going to cut it for precise orbital maneuvering; GREAT for the initial boost to lunar orbit, but for precise maneuvering is going to be really difficult.
So, without actually reducing the amount of limited water on the moon, I figured the only way to do RCS and small orbital adjustments with ISRU, would be a combination rocket that uses powdered aluminium, and some form of oxygen feed system to make a hybrid powder/gas rocket.
What I'm having trouble with is the feed system for the precise measurement of the powder to oxygen ratio.
I've thought of a arcemedies screw, drawing from a cylinder filled with the powdered aluminium, that has a piston at the top to push the powder down towards the screw.
OR, a solid aluminum plug, that oxygen blasts through and ejects into multiple tubes (RCS ports) with valves and shit like that to control where the thrust goes to.
Anyway, does anyone have any ideas for a zero-g feeding system for a powdered propellant?
(BTW, Elon, Bezos, do not steal this idea because I will know about it.)

This is not only a form of disinformation, but also gatekeeping. Because it means it becomes much harder to learn the fundamentals of QM without actually digging deep into the papers.
Take for example this guy https://www.youtube.com/watch?v=A9tKncAdlHQ
His explanation is deeply wrong on two accounts:
- You CAN actually observe the path taken with up to 98% certainty before losing the interference pattern (https://sci-hub.se/10.1007/BF00734319)
- "Unplugging the detector" can still cause the pattern to collapse, depending what you mean by that. Whether it collapses or not has nothing to do with whether humans are observing it. If you simply unplug the screen that the scientist is looking at, the interference pattern will stay absent. (Heisenberg 1958, Physics and Philosophy)
Then there is nonsense like this https://www.youtube.com/watch?v=TfouEFuB-co
Why are PhDs engaging in this nonsense? Do they actually not understand QM, is it wishful thinking combined with sunk cost fallacy, or are they doing it simply for the money? I think the first video might be a case of doing it for the money, while Penrose is doing it because of wishful thinking that humans are special, and now he's too deep in it to backpedal without looking like a fool.
Is there any physicist who actually believes the conscious observer nonsense in current year and is not bending the truth for their own personal gain? I'd like to know.
Why isn't this kind of behavior called out more frequently by respectable scientists? Is it because of fear?
Sometimes when I ask him to do things I almost feel the immense effort it would take to complete them.
And she, obviously, does everything (almost) perfectly without batting an eye.
This inability to experience fatigue is shocking.
Needless to say, even these stupid and primordial AIs are already changing my way of working completely.
It's not just hype, I'm realizing it firsthand by using them.

Shaza Negm, 15, died Saturday from health complications
>after suffering cardiac arrest while training at
when she fell into a coma during exercise.
Negm was active in the swimming team at Tanta Sports Club.
She had won many international and local sports championships representing Tanta Club and won more than eight medals between gold, silver and bronze over the past five years. (yes she won a medal at age 10)
The young swimmer was transferred to the ambulance unit located at the Olympic pool in one of the private clubs in the city of Tanta.
Negm was given first aid and received treatment in Gharbia Governorate, before being transferred to the Nasser Institute in Cairo where she passed away.
Her heart stopped during exercise and she lost consciousness in June. She was also found to have ulcers, bled severely, and lost hemoglobin during her stay in the hospital.
She underwent five surgeries in an attempt to save her life, but eventually succumbed to her coma when her brain gave out. The Ministry of Youth and Sports mourned Negm’s death on Saturday.

How much of a big deal is this? Some of my leftist friends are posting demotivation messaging like
>"if only we opened our borders to China and cooperated with them, they would give us access to their wonderful technology which is 10-15 years ahead of the US!"
None of them have any formal technical qualifications in the sciences. Does China objectively lead by a significant margin (e.g. beyond a 5 year gap) in any major scientific field? I know that I'm opening a can of worms that may invite bots and shllls in asking. I'm looking for information and talking points to rebut the sensationalism of my worryingly self-hating, naive and pessimistic acquaintances. It's getting fucking tiresome. Sorry in advance.

Why are scientists so creatively bankrupt?
Yes, another one, because there was another Nobel Prize in Medicine, also at Stanford, was caught committing scientific fraud a few months ago. At this point, should we audit all research papers from the people who won the Nobel Prize in Medicine? To make an example. my guess is could be around 10-20% of all their published crap are fraudulent bullshit.
Remember that all the fraud that ever get caught are braindead copypasted stuffs so if those frauds literally just spend one or two hours tweaking stuffs a bit it would be impossible to get caught. the percentage of fraud in reality is actually higher.
Second question, is the backyard independent scientist extinct in today's world?
I have no reason to believe this is useful in any way. I also am unsure if it would actually work. It's based on a combination of simulator outputs and journal articles, all of which work generically, but I don't have the formal education to know if there are side reactions or if some of the groups are deactivating in this instance, or if the usual workups are inapplicable.
It is entirely the product of a deranged mind with too much time available.

Since the planet is generally cooling off since the height of the current interglacial period, sea level should be falling currently.
And observational evidence shows that sea level is currently falling.
Hypothesis proved true
Higher rejection rates for double blinded vs single blinded reviews prove illicit collusion occurs between authors and reviewers in at least a third of academic publications
There's nothing new under the sun, we're just publishing more and more bullshit.
This is very important because if we finally realize that technology is dead and there's no more progress to be had we can conclude that corporations and silicon valley are stealing our money with R&D and contrived bullshit.

How true is it really?
I have trouble believing that any amount of sun exposure is potentially harmful considering how modern this view is. For millennia people did not all die of skin cancer and many thought sun exposure was good for you. While health authorities sometimes accept that some amount of sun exposure is good for you, they always say it's only a little bit of sun exposure and insist you still wear sunscreen.
Something else I know is that in the past several decades myopia rates have been greatly increasing, and myopia can be caused by a lack of time outside. Could our discouragement of going outside be causing myopia?
It is proven that our current geological period (the Quaternary) is an Ice Age. If anything, warming the planet would turn it back to normal, when the planet had huge forests and animals like in the Mesozoic.
Also, on a geological time frame, we should give ALL the carbon back to the biosphere before it is forever absorbed into the surrounding rocks or subducted to the mantle, or else the planet could eventually run out of biological materials for life. We will probably achieve fusion before the lack of oil becomes a problem anyway.
Either way, the greenhouse effect will not be very dramatic, because most of the CO2 will be quickly absorbed by the biomass in the planet. Proof of that is that originally the atmosphere had only volcanic gases and zero oxygen, and today it has 20% O2 and 0.04% CO2. Almost all of the carbon was absorbed by photosynthesizing organisms. The same thing is happening RIGHT NOW due to human emissions, but the scientists are trying to paint it as a bad thing (https://www.nature.com/articles/s43247-024-01228-7). Thoughts?
How the hell is evolution not adaptation, and adaptation not evolution?

At 521 pages it is a comprehensive report containing hundreds of figures and a detailed examination of excess all-cause mortality during the years 2020 to 2023.
“Our calculated excess mortality rate [ ] corresponds to 30.9 ± 0.2 million excess deaths projected to have occurred globally for the 3-year period 2020-2022, from all causes of excess mortality during this period,” the authors wrote.
More than half of those global excess deaths, about 57%, the authors attributed to covid vaccines.
Using the data from 78 countries the researchers calculated the population-wide risk of death per injection. From this, they estimated the global all-ages excess mortality associated with covid vaccines up to 30 December 2022. They calculated that the deaths, globally, associated with covid vaccines up to 30 December 2022 was 16.9 million people.

Conclusions
The consistency seen among cases in this review with known COVID-19 vaccine mechanisms of injury and death, coupled with autopsy confirmation by physician adjudication, suggests there is a high likelihood of a causal link between COVID-19 vaccines and death. Further urgent investigation is required for the purpose of clarifying our findings.

>AI could help engineer organisms that react to their environment (like an organism that helps crop production by sending signals to plants in response to qualities of the soil)

>More GMO food, like lab grown meat (even gayer)
Schizo-tier:

>GMO Humans/Human chimeras
>Engineered neurons connected to a computer to make a living computer
