Quantum Mechanics

Quoted By: >>14409292

Quantum Mechanics says that particle can travel through space at a fixed point in time. How is this possible given the notion that we know space and time are pretty much inextricably linked?

Wouldn't it be better to come up with an equation that is independent of space and time? I don't even know how you would do that

not true at all
all quantum physicists worth their salt know the the "quanta" are abstractions of an underlying field which is continuous, i.e. that there's no such thing as any "particle", only wave packets
>«Integers are not inputs of the [quantum] theory, as Bohr thought [Danish physicist Niels Bohr “implemented” discreteness at the atomic scale]. They are outputs. The integers are an example of what physicists call an emergent quantity. In this view, the term “quantum mechanics” is a misnomer. Deep down, the theory is not quantum. In systems such as the hydrogen atom, the processes described by the theory mold discreteness from underlying continuity.»

Yes it would increase moisture and rain. But it doesnt matter if the desert is let as desert. Nothing is lost from the desert continuing to be desert. Its a bad investment, a lot of work and money over some rain with minimal economic impact

>clinicians were able to pinpoint a major component of bacterial cell membranes through a molecule called lipopolysaccharide (LPS) which can trigger "pro-inflammatory molecules" such as the protein and cytokine oncostatin M (OSM)
>The researchers found that blocking the OSM can reduce severe asthma-related symptoms in mice, leading to the potential development of antibodies and other medicinal drugs against OSM pertaining to asthma treatment.
>a potential cure is possible in the future if the scientific community further understands the mechanisms surrounding asthma and its relation to both microscopic living organisms, such as germs or pathogens.

Are chronic conditions like asthma, arthritis, etc. going to be cured in our lifetimes?

It can be prevented by early exposure to allergens. Ensure your pregnant wives eat allergen-laden foods like peanut butter and low-mercury fish to ensure babies come out prepared to eat such foods and continue to feed babies those foods after birth (no honey until 2 though).

That Anon isn't too far off, though. Best evidence is that things like peanuts can be introduced around 6 months, as long as the child is considered low risk for eczema. Honey, however, contains Clostridium spores which are typically destroyed by stomach acid in older children and adults but not by young children, so they're at increased risk of botulism and tetanus.

Mechanism in medicine means jack shit. This is not a hard science like physics. For every one mechanism you postulate there are 1000 different mechanisms that you don't know about and for all you know altering the mechanism you know about will be a drop in the ocean compared to all the other factors involved here. The only way you can know is via clinical trials.

Yes. It's the same. There is no difference. Even if one is conditional on the other, it makes no difference, it's all captured in AND.

It's literally an intersection of sets. Of course A and B is equivalent to B and A.

Now, P(A|B) /= P(B|A), but that's a different problem.

It's pretty clearly stated desu. The definition of a probability is simply:
P(A) = N(A)/N(U)
Where N(A) is the number of items in the set A and N(U) is the number of items in the set of all outcomes possible for a given event (like rolling dice).

Ok, let me put this VERY CLEARLY:

Let $U$ be the sample space. Let $A\subseteq U$ and $B\subseteq U$ .

THE DEFINITION OF SET INTERSECTION IS:
$X\cap Y = \{z: z\in X and z\in Y\}.$
SO BY DEFINITION, FOR ANY SETS X AND Y, $X\cap Y = Y\cap X$ . IF YOU WANT TO BE EVEN MORE EXPLICIT, ITS NOT HARD TO SHOW FROM HERE THAT $X\cap Y\subseteq Y\cap X$ AND $Y\cap X\subseteq X\cap Y$ .

Thus, $A\cap B = B\cap A = S\subseteq U$ .

THE FIRST AXIOM FOR PROBABILITIES STATES:

For every subset $E$ of the sample space $U$ , $P(E)\in\mathbb{R}$ and $P(E)\geq 0$ .

BECAUSE $A\cap B = B\cap A = S$ ARE ALL THE SAME SUBSET OF $U$ , THEY MUST BE ASSIGNED TO THE SAME REAL NUMBER BY $P$ .

THAT IS, BY THE DEFINITION OF SET INTERSECTION AND THE FIRST PROBABILITY AXIOM,

$P(A\cap B) = P(B\cap A)$ .
