Yes he was. He literally claimed to be the son of the Jewish god.
You should actually read the image I posted, it may clear things up for you. Multiple groups can worship the same god in different ways, it doesn't make those groups the same.
Different countries usually have slightly different number symbols.
I don't read schizo propaganda.
Let me make it simple enough so even a stupid retard like yourself will understand it.

If you believe in only the kike god, then you're a kike.
If you believe in the kike god and Jesus, then you're a Christian.

And before you say anything, yes, muslims are the biggest kikes of them all.

What makes belief in String Theory more alluring over the belief in Quantum Field Theory? Does one offer more advantages in ones daily life? Is its eschatology more in line with the modernistic scientific ideology?

Isnt the field just probability of the particle? Lack of information due to hidden variables?
I should clarify: Quantum mechanics of any kind (fields, particles, strings, any of it) don't exist except as a conceptual crutch to patch up incorrect models that don't work.
>atoms dont exist
Where did I say that? Quantum mechanics deals with things SMALLER than atoms. Those are the things which don't exist.
>Isnt the field just probability of the particle?
No. The fields in QFT are more like the classical electromagnetic field than the Schrodinger wavefunction.

>What makes belief in String Theory more alluring over the belief in Quantum Field Theory?
String theory and QFT are not directly in opposition and the the guy in the Twitter screencap sounds like an idiot.

Two more weeks, vaxxie mass death soon, anti-vaxxie bros win the internet argument and go back to cooming in socks

A quick look at the overall casualties from the CV19 vax reveal an unparalleled medical disaster. Dowd explains:

“I went before Senator Ron Johnson in February to talk about the ‘pandemic scorecard,’ which is abysmal.

Ever since the CV19 vaccine came on, we have had 1.1 million Americans die excessively, 4 million permanently disabled and another 28 million injured. It’s 33 million people who have been negatively affected now.

The question you have to ask is why are these institutions not screaming from the rooftops? I think the reason why is, it’s all because of the (deadly) vaccine. It’s all circular, and I think it’s a joke at this point.”

One big problem Dowd has spotted is an explosion of cancers and, yes, you cannot get the truth about this either. Dowd says:

“The fact that people will not even say that cancers are on the rise is pretty comical to me. Doctors were reporting it anecdotally, and now we have the data to prove it. This is where we are...

In 2022, I said that ‘60,000 millennials died excessively between March of 2021 and February of 2022. That was a Vietnam War.’ That tweet went viral, and Reuters and AP fact checked me and said no, our experts say that’s not true.

Now, even the establishment is saying there is excessive all-cause mortality. So, we are now in a stage where cancers are not rising. They are now denying that. The lies are just unreal.”
but everyone across the board was more likely to have gotten cancer in 2022 compared to just 3 years ago
in fact, the only people who didn't were the extremely elderly
Is that why 4chan has dwindling numbers?

No, when you run, you skip over a bunch of points with each stride, so you don't have to step on every single point in your path to traverse the path.
Middle school physics: for every x distance traversed by A there's B traversing x+n distance. It follows there must be a point at which the difference between two functions (distance A = time * speed A and distance B = time * speed B) is bigger than the difference between the starting points of the pursuit.

Intellectual Functioning and Personality Traits
Higher scores on Wechsler scales are generally associated with better intellectual functioning, such as higher IQ scores. While these scales do not directly measure personality traits, there can be indirect correlations between intellectual abilities and certain personality dimensions. For example, individuals with higher intellectual abilities might demonstrate traits like openness to experience, curiosity, and a willingness to explore complex ideas.

Emotional Regulation
There's a connection between cognitive abilities and emotional regulation. People with stronger cognitive skills may be better equipped to understand and regulate their emotions, leading to a more balanced personality. On the other hand, deficits in cognitive functioning, as measured by Wechsler scales, could be associated with difficulties in emotional regulation, potentially leading to symptoms like anxiety or depression.

While Wechsler scales are not diagnostic tools for psychiatric conditions, certain patterns of cognitive strengths and weaknesses can be associated with different clinical symptoms. For instance, specific cognitive profiles may be linked to conditions such as attention-deficit/hyperactivity disorder (ADHD), autism spectrum disorder (ASD), or specific learning disabilities. These conditions can influence aspects of personality and behavior.

Cognitive Styles
The way individuals process information, solve problems, and approach tasks can also be linked to personality dimensions. For example, someone with a highly analytical cognitive style might exhibit traits like skepticism or a preference for detailed, structured thinking. These cognitive styles can intersect with personality traits and influence how individuals respond to various situations.
Executive Functioning and Behavior
Executive functions, which include abilities like planning, decision-making, and impulse control, are closely related to cognitive abilities assessed by Wechsler scales. Deficits in executive functioning can manifest as impulsive behavior, poor decision-making, or difficulties in social interactions, which can impact personality expression and contribute to clinical symptoms.

Scientists have developed a new solar-powered system to convert saltwater into fresh drinking water which they say could help reduce dangerous the risk of waterborne diseases like cholera.

Via tests in rural communities, they showed that the process is more than 20% cheaper than traditional methods and can be deployed in rural locations around the globe.

Building on existing processes that convert saline groundwater to freshwater, the researchers from King’s College London, in collaboration with MIT and the Helmholtz Institute for Renewable Energy Systems, created a new system that produced consistent levels of water using solar power, and reported it in a paper published recently in Nature Water.

If green land creates oxygen and green land is created by water and humidity.

If we could create some seas in the middle of Sahara and other arid places as Middle east, Austrialia. wouldn't that create rain and humidity for nature?

Let's say we construct some nuclear power plants on the coast of Sahara, that can power some big pumps, and a pipe as gazprom constructed in Europe. till the middle of Sahara. and pump water from sea few years

If it would be big enough, wouldn't that create humidity and rain?

It wasn't a forest, but a grassland and a savannah. The Hadley cells tilt northwards and southwards throughout the ages, IIRC due to earth's axis "wobbling" like a spinning top. The Sahara will be green again in about 10000 years.
Sahara is at the same lattitudes as India or the Carribean, obviously there must be more to it.

There are two things that will forever be impossible for us to understand: the speed of light and quantum mechanics.

The speed of light simply makes no sense, but it works on paper 100% of the time.

Quantum mechanics cannot be understood because Feynman showed that Quantum Mechanics cannot be calculated by classical computers. Predictions can be made by classical computers, but the actual mechanics of the quantum world cannot be explained or even understood classically. As our brains are classical computers they will forever be incapable of understanding quantum physics. Even if we built a quantum computer that could understand quantum mechanics that computer could not explain it to us.

We will never know.

Can someone explain the law of identity to me?

It is claimed that for all subjects x, x = x. But I cannot think of anything that can be said of a thing other than its predicates, implying that "x = y" is equivalent to "For all predicates P, P(x) iff P(y)". If this is the case, the law of identity reduces to "P(x) iff P(x)", which is the law of noncontradiction. Am I misunderstanding the meaning?

>But I cannot think of anything that can be said of a thing other than its predicates

The idea that two things are equal if they share all the same properties is not expressible in first order logic. So the law of identity is a bit different than what you are saying.
Look up the concept of intensional vs extensional equality. If law of identity reduces to P(x) iff P(x), then you are talking about intensional equality. Now consider two different definitions of pi:
>The limit of area of regular n-gons with apothem length 1 as n goes to infinity
>Liebniz formula: 1-1/3+1/5-1/7+...
We can write them both as definitions of pi, and thus, they can be considered extensionally equal in some world, but it is clear that not every predicate about one is true about the other:
>They convergence at different rates
>One implies the existence of some geometry
There you have it. We're doing no more than making a rule about how '=' can be used in the symbol game.
The sign doesn't say anything about what is equal to what. You have to show this using axiomatic statements that leave nothing to ambiguity.
Retard. It’s just the definition of the sign there for algebraic manipulation. It’s not a logical concept but a purely symbolic one
It means that x is a member of its own equivalence class

>"if you want to both appreciate and make great food, it is necessary to have a great palate, but not if you only want to appreciate it" is a semantically valid interpretation of your sentence.
That's a contradiction. It's literally meaningless (not semantically valid). But instead of recognizing that interpretation as such, you've attributed a different meaning to it out of thin air. Regardless, even if you actually had explicit reasons to disagree with me, it's clear why you're doing it, and why I shouldn't bother.

> if the French must have a good palate because they developed French cuisine, it stands to reason that anyone who develops a shit cuisine would have a correspondingly shit palate.

Again: https://en.wikipedia.org/wiki/Affirming_the_consequent
>That's a contradiction.
No it isn't. Doing both requires a great palate. Doing only one does not. No contradiction. Maybe read everything again as slowly and as many times as you need?
>even if you actually had explicit reasons to disagree with me
I do, and I fucking explained them above for any moron to fucking understand, you fucking retard.
>if the French must have a good palate because they developed French cuisine, it stands to reason that anyone who develops a shit cuisine would have a correspondingly shit palate.
That's not affirming the consequent, it's inductive reasoning. You rightfully point out that your statement leaves room for people having a great palate and yet not producing a great cuisine. I, however, am introducing another premise here. Just as a great palate produces a great cuisine, so a shit palate produces a shit cuisine. It's not conceptually the mere absence of a great cuisine, it's the presence of its antithesis. Again, just because I'm disagreeing with you that doesn't mean I don't follow your logic. I'm rejecting your premises.
All right, so, firstly, the notion that the French have great taste because they have great food and you know it's great food because they have great taste is circular.
Secondly, the implication that if even a single Briton appreciates French cuisine it therefore means that the Britons as a whole appreciate French cuisine seems like a hasty generalisation. I would also bet there are many more fast food restaurants in the UK than French haute cuisine, but you attach no conclusions to that fact.
Thirdly, I disagree with the notion that a refined palate is necessary to enjoy good food. Someone can go to a great steak restaurant and eat a great steak and like it, but still prefer steak well-done with ketchup. And he'll be full after his meal either way. And if you say that appreciating the food is not necessary to eat at a fine restaurant, then the existence of French restaurants in London obviously tells us nothing.
Fourthly, you lack an explanation for the existence of terrible cuisines. You posit that a great palate is necessary but not sufficient for developing good cuisine, but why? Whence cometh terrible food then? This assumption seems tailored to the needs of your conclusion that white people universally share great taste regardless of any evidence to the contrary.
Finally, I think that if you told an Englishman and a Frenchman that they must appreciate the same food due to their shared "whiteness", the best response you can hope for is laughter. Because Nigel might smack you for implying he eats frogs and snails, and Pierre likewise for comparing his national pride to beans on toast. Just about the only thing both cuisines have in common is an aversion to spices, come to think of it...
You are too stupid to understand high-school-tier reasoning and too arrogant to compensate through any other means. That's why you're so resentful and hate whites, and since you lack the ability to achieve anything by yourself, you've amounted to biting the hand that feeds you. I've never met someone as persistent in his stupidity before, and now it's clear to me the ideals of the Enlightenment could never work with the likes of you.
>You are too stupid to understand high-school-tier reasoning
No, I'm simply more advanced than your high-school-tier reasoning. You have yet to address any point and instead just insist that unless I capitulate to you entirely it must be because I'm simply too stupid too understand you. You've yet to shown an ounce of understanding of my criticisms of you.
>now it's clear to me the ideals of the Enlightenment could never work with the likes of you.
