Ultra-pasteurized milk has a remarkable shelf life, even when unrefrigerated.
And how is it better for us? Considering a majority of the world can’t digest it is a big sign as to why plant based is better.
Your argument becomes a non-sequitur when extended to people who are lactose tolerant. The mere existence or ubiquity of lactose intolerance does not entail that milk is bad for the lactose tolerant. Perhaps plant substitutes to cow milk are better for even the lactose tolerant, but lactose intolerance is completely irrelevant to the minority of us such as myself who produce sufficient enzymes to digest lactose without any difficulty whatsoever.
Also, I constantly name files in the same directory the same thing except for case. In my ~/tmp directory I have unrelated foo.c (C source) and foo.C (C++ source).
I meant that electromagnetism is ubiquitous in its role in the nature of ordinary matter itself.
Are magnet’s the most dangerous thing in the universe?
No, not even remotely. That’s not to say that the extreme magnetic fields of magnetars wouldn’t be awesomely dangerous, but “most dangerous thing in the universe” is an absurdly high bar to meet.
After all Blackholes are powerful magnets
The accretion disk consisting of material surrounding a black hole is capable of generating strong magnetic fields, rather than the black hole itself.
Hello. I’m in my mid 20s. I was mute in my early youth and had to attend speech therapy classes in preschool and early in elementary school, and I rode the short bus. I played with and spoke to my stuffed toys until I was in middle school and that was when my parents took them away. My family always said that I was an odd...
I can’t be the only one who absolutely hates the idea of a particle having two states at once, right? Is it just a personal thing or is it tied somehow to the fact that autistic people generally have more binary thinking?...
There is absolutely no evidence that consciousness causes wavefunction collapse (that is, if wavefunction collapse even happens at all, but that is a different discussion entirely).
You appear to be discussing quantum indeterminacy, measurement, and wavefunction collapse rather than the uncertainty relation. Also, quantum indeterminacy is not a matter of “knowledge”, as you seem to suggest.
The particle does have a state before it’s observed—it just might not be an eigenstate with respect to the variable that shall be measured, but rather there is a well-defined distribution in said variable which comes from the wavefunction.
… the state of a quantum particle is fundamentally ambiguous before measurement. This is demonstrated by experiments breaking the Bell inequality …
No, the state is not what’s ambiguous, but rather a single, definitive value of the variable is what does not exist unless it’s already in an eigenstate of said variable.
Yes, I am aware of what you meant, but your wording may be misleading.
I always thought it was just not possible to measure… without changing [the system being measured]
This is the observer effect, which is certainly not unique to quantum mechanics.
I always liked to think of it like christmas presents - you don’t know what the inside looks like until you open it. It could be anything!
That analogy is suggestive of hidden variables. Hidden variables theories are severely constrained by observed violations of Bell’s inequality. Without loopholes like non-locality, there cannot be a “hidden” definite value underlying a superposition state.
If you have any source with credible evidence of consciousness causing collapse, I would like to see it.
Even if it were a matter of opinion among experts, the position that consciousness causes collapse is hardly a common one, despite your attempt at claiming the contrary.
Other than some issues with wording (i.e., the misuse of “state”), those are some good questions.
It turns out under reasonable assumptions that any theory that attempts to always assign deterministically evolving “hidden” definite values to measurable quantities while reproducing the predictions of quantum mechanics must be nonlocal. This does not mean that such nonlocal hidden variables theories are necessarily wrong, but introduces issues such as the incompatibility of the dynamics of the hidden variables with the theory of relativity. However, the “standard” Copenhagen interpretation has the same issue of nonlocality in the case of wavefunction collapse.
A second issue with such hidden variables theories that are faithful to the predictions of standard quantum mechanics is that they are often essentially standard quantum mechanics with added complexity in the form of the hidden variable dynamics, which would be undesirable from the perspective of Occam’s razor, which disfavors unnecessary complexity.
A third issue is the question of how measurement of a quantity would reveal the true, definite hidden variable value. The Copenhagen interpretation has a similar issue with the question of how measurement causes wavefunction collapse.
One may ponder the hidden variable theories that disagree with the predictions of standard quantum mechanics, but experiments investigating these differences in predictions have repeatedly favored the predictions of standard quantum mechanics to an overwhelming degree.
Literally every source suggests that the wave function collapses due to being observed.
This claim that every source suggests that the wave function collapses due to being observed by a conscious being, and only by observation by a conscious being (which is presumably what you meant given the original context) is blatantly false. Give me a single reputable source that makes such a claim of consciousness causing collapse as anything other than a statement of (minority) interpretation.
Unless you’re a Nobel-winning physicist, it’s unclear how you are an authority whose opinion matters.
This is insulting. You are ludicrously claiming that expert opinion agrees unanimously that consciousness causes collapse (despite it actually being seen as a minority view by the community), yet have the audacity to say that my opinion on the matter is useless, despite the fact that I am a senior physics/mathematics double major at a major university with a respected physics program (and which includes multiple Nobel laureates in physics, since you mentioned it). I have already taken both undergraduate quantum mechanics courses as a junior; moreover, I currently only have one more physics course (along with several more math courses and one more general education requirement) required to graduate.
Obviously, this does not make me an expert on the topic in any sense whatsoever, but I think you are in no position to suggest my opinion isuseless.
But I do like the implication that I get to determine what’s “real” because the quantum universe doesn’t collapse into a single state until my consciousness interacts with it.
To get right to the point, the idea of consciousness causing collapse is a minority interpretation of quantum mechanics (one that was originally conceived more as a hypothetical alternative interpretation without full seriousness being given to it in its own right) that has been given undue credit in the public eye by the dishonest purveyors of quantum mysticism (like Deepak Chopra) who confidently attribute supernatural attributes to quantum theory with neither any explanation nor even the simplest indication of understanding of even the simplest of an introduction to the topic, let alone any authority on the topic. The part of your comment, “I get to determine what’s ‘real’”, seems to indicate your familiarity with quantum mysticism beyond just the idea of consciousness causing collapse.
NO, there is absolutely no evidence of any fundamental role of consciousness in quantum mechanics, but you may have been mislead into believing there is. If you have any such credible experimental evidence of consciousness causing collapse, you would be the first to provide such.
Not today, sorry. (startrek.website)
