Re: æðрь áûðòÑÂý's Aether model of QM.
Greetings,
Now, it appears, that you accept that air is the best explanation of things concerning air.
I have indicated that, in order to discern between subjective and objective reality, the Scientific Method is used to test for and verify whether something is (externally) real or not. Science approaches "Truth" like the Newton-Raphson Method - even if we may never actually reach it.
Really??!!
What arrant nonsense!!
Then you'll get the "white-out" to which I referred earlier!
And by using the adjective "invisible", what you really mean is "undetectable", which - by definition - negates the ability of anyone to prove its existence or non-existence.
We cross-check everything we can - after that, we have to accept that we can't be "absolutely, 100%" certain: but we can go forward and live our lives and make progress.
In reality, that isn't the case.
We use the Scientific Method to reduce the likelihood of error as much as possible. And on that basis we make progress to more a accurate understanding of how Nature works.
The helicentric model is a closer match to the reality of how the Solar System is arranged.
Geocentric model
"A geocentric frame is useful for many everyday activities and most laboratory experiments, but is a less appropriate choice for solar-system mechanics and space travel. While a heliocentric frame is most useful in those cases, galactic and extra-galactic astronomy is easier if the sun is treated as neither stationary nor the center of the universe, but rotating around the center of our galaxy, and in turn our galaxy is also not at rest in the cosmic background.^
Basically, tracking satellites or finding the RA/Dec of stars is easier using the geocentric model - however, to change the trajectory of spacecraft in the gravitational field of the Sun, it's more appropriate to use the heliocentric model.
If we ever travel to the stars, we'd use a galactic-centred model - the other two would simply result in our getting hopelessly lost (you'd no longer be able to detect the Earth - or, even, the Sun).
Consider...
How could we prove categorically which body orbits which (we'll assume here that we're including barycentres)?
One way would be if we could observe the Solar System from a vantage point above/below it - from where we could observe the Sun-Earth "dance".
That's what the Ulysses Mission has been doing for nigh on 20 years.
Which is why Science is based on lots and lots of people making the same observations, doing the same experiments, collating/analysing/synthesizing the results and cross-checking those results through peer-review.
Can you improve the Scientific Method? Without adding unnecessary steps?
The Scientific Method is the simplest it can be without people ending up becoming paranoid and cross-checking everything ad infinitum.
Only through the Scientific Method can we make steady but certain progress.
There's nothing else that'll allow us to progress.
That was not what you implied - nor intended.
As I, and others, have already pointed out, it had nothing to do with the Scientific Method - nor peer-review related to scientific theories or experimental results.
It was a lack of objective peer-review in the Humanities at that university.
There is a vast difference between arguing philosophical points and scientific ones - the latter must pass muster through observation and experiment; that is the litmus test for Science.
Arguing about philosophical matters, like "Virtue" or whether God exists or not is undecidable - like the undetectable Pink Unicorn. It's just one person's viewpoint versus another's, with no means of testing it objectively.
Unlike Science.
As I've already pointed out.
You appear to suffer from what's called "Man's need for certainty in a uncertain world".
Life - Nature - is not a zero-sum game, it's not "all-or-nothing".
Given that the Earth is, in fact, round (an oblate sphere, to be precise), not only is his calculation wrong - but the manner in which he applied the formula.
There are other problems with his approach:
He assumes that the Bedford Levels were ... level - even though he states that there was a flow of water, which indicates that they're not.
He was looking "up-slope", which would add to the "height" of the horizon.
Worst of all, he seems to have been unaware of Aristarchus' attempt to measure the distance of the Earth from the Sun - Aristarchus was unable to measure the angle the Sun made (it's virtually 90 degress) which would have given Rowbottham some idea of how far wrong he was!
All I said was that the Scientific Method is used to discern whether a observed phenomenon was in our head or external to us - to ensure that errors weren't made in observation or experimental results.
Kindest regards,
James
Greetings,
Lecture 21: The Rotation & Revolution of the Earthæðрь áûðòÑÂý said:Anything you got.What evidence will you accept?
Pulsar (and others) have already explained that it wasn't detected.æðрь áûðòÑÂý said:Then what did it do? The predicted values was the one measured by the experiment. And tuhs the best explanation is that it was detected.You continue to claim that the MG experiment detected the aether - it did not. Your linking to the other article is a effort to prove its existence by "proving" that it's the aether that's turning (even though it doesn't explicitly state the word: in effect, if it's not the Earth that's turning, then...)
Yet more prevarication - you contradict yourself with regard to your previous post.æðрь áûðòÑÂý said:Just as the air is the best explanation of things that we observe concerning air.
Now, it appears, that you accept that air is the best explanation of things concerning air.
As already explained, the aether does not exist because none of the experiments have shown any evidence for it.æðрь áûðòÑÂý said:In the same way is this and other experiments best explained by an aether.
Same prevarication/equivocation as above!æðрь áûðòÑÂý said:No. I'm saying that air is the best explanation for what goes on in the atmosphere.That is complete nonsense!
We already have valid explanations for these - with verifiable evidence.
You're claiming that the atmosphere is actually aether? What?! All of it?? The same or different types???
Again, no evidence.æðрь áûðòÑÂý said:Just as the aether is the best explanation for the MG and other similar experiments.
At no point have I said - or implied - "ultimate truth".æðрь áûðòÑÂý said:No, my point is that all those observations were made by people throught their senses you claim are failable. Thus, they are not reliably to give us the ultimate truth.Your claims are false - I know this through empiric observation and experimental evidence, carried out over centuries by lots and lots of people all over the world. Yet you claim that all of these are wrong and your explanation is right?
I have indicated that, in order to discern between subjective and objective reality, the Scientific Method is used to test for and verify whether something is (externally) real or not. Science approaches "Truth" like the Newton-Raphson Method - even if we may never actually reach it.
"At least 1000 miles".æðрь áûðòÑÂý said:We don't know that. At least 1000 miles.You're equivocating again.
First you refer to it as a "shell" - consistent with a geocentric model - now you claim it isn't a actual "shell", just "empty space" and that it's "at least as big as the observable universe".
So - how big is that??
Really??!!
What arrant nonsense!!
Then you'll get the "white-out" to which I referred earlier!
Avoiding the question, I see...æðрь áûðòÑÂý said:Prove that an Invisible Pink unicorn does not exist!Prove that it isn't.
And, in case you ask me to do prove that it is, you should be well aware of what Science already says about that.
And by using the adjective "invisible", what you really mean is "undetectable", which - by definition - negates the ability of anyone to prove its existence or non-existence.
You can only have anything from 0% up to - and including - 100%: not "10000000000000%".æðрь áûðòÑÂý said:You missed my point by about 10000000000000%.Your original statement was made with the intention of proving your point: that Science and scientists are not to be trusted - they make their results conform to what they want them to show. In effect, there's a conspiracy amongst scientists to fake their research/results.
My statement was a denial of this allegation.
And as I've already pointed out - no-one here is talking about "ultimate truth".æðрь áûðòÑÂý said:I simply said that scientists are people, and people are failable, thus they can not by definition tell you the ultimate truth. They can't by definition. I'm not accussing anyone of anything.
...so there's no point in trying...æðрь áûðòÑÂý said:It doesn't matter how good you check it, there is always a chance you will miss something.Instruments are calibrated prior to experiments - this is the same in any practical field, such as computer maintenance (electrical testing equipment is checked to ensure that it's working prior to a engineer using it - I know, I've worked in the industry).
We cross-check everything we can - after that, we have to accept that we can't be "absolutely, 100%" certain: but we can go forward and live our lives and make progress.
No - we go one step further: we identify which descriptions match the observable workings of Nature. Those that don't are discarded.æðрь áûðòÑÂý said:It depends on what you need. If you need ultimate truth, then no. If you simply want descriptions of of how nature works, then yes.We all know that. You speak as if nothing can be trusted - ever - under any circumstances.
But not descriptions which match Nature's workings - merely hypotheses. And yours has been discarded through centuries of observation and experiment (space travel, to name but one type).æðрь áûðòÑÂý said:But I'm not claiming that my statements are the ultimate truth. I'm simply sayign that they are descriptions of how nature works.If that's the case, then no-one would be able to make any statements about life, the universe or anything - yet, that doesn't stop you from making all sorts of claims which fly in the face of human history and science.
"Philosophically" anything can happen!æðрь áûðòÑÂý said:Yup, and philosophically that still means that a mistake can happen.The probability of one person being wrong is 0.5.
The probability of a thousand people being wrong is (0.5)^1000.
Now, what's the probability of millions upon millions of people - all over the world, throughout human history - who've made observations, which are reviewed by others; who carry out experiments, whose results are verified through further experiments - making a mistake?
In reality, that isn't the case.
We use the Scientific Method to reduce the likelihood of error as much as possible. And on that basis we make progress to more a accurate understanding of how Nature works.
History.æðрь áûðòÑÂý said:What numbers?I have the weight of numbers on my side.
It is not "as precise as the Copernican today".æðрь áûðòÑÂý said:You don't get it, the Tychonic model is as precise as the Copernican today. And simply claiming that it does not work is meaningless.If the mission planners had used a geocentric model - any model - they would have been lost. Claiming that "we just need more time to correct our model" would be pointless.
The helicentric model is a closer match to the reality of how the Solar System is arranged.
æðрь áûðòÑÂý said:Why not?Only on Earth or near-Earth - not out in the big, wide solar system.
Geocentric model
"A geocentric frame is useful for many everyday activities and most laboratory experiments, but is a less appropriate choice for solar-system mechanics and space travel. While a heliocentric frame is most useful in those cases, galactic and extra-galactic astronomy is easier if the sun is treated as neither stationary nor the center of the universe, but rotating around the center of our galaxy, and in turn our galaxy is also not at rest in the cosmic background.^

One way would be if we could observe the Solar System from a vantage point above/below it - from where we could observe the Sun-Earth "dance".
That's what the Ulysses Mission has been doing for nigh on 20 years.
It's not an assumption - the evidence indicates that it does.æðрь áûðòÑÂý said:But this measurement has been produced based on the assumption that its teh Earth that is orbiting the Sun.The stars aren't "smaller" - as the measurements from a number of different methods have shown.
Which is why we use the Scientific Method to mitigate that possibility.æðрь áûðòÑÂý said:No, I'm just saying that people are failable.You appear to believe that all people are morons - and that there is no point in having more people cross-check observations or experimental results - because the human race is a race of morons, therefore, there's no point in even trying.
Which is why Science is based on lots and lots of people making the same observations, doing the same experiments, collating/analysing/synthesizing the results and cross-checking those results through peer-review.
Again, you have this obsession with "ultimate truth". No-one is expecting to gain "ultimate truth" in everything.æðрь áûðòÑÂý said:If you don't need to improve it, then you claim that you have the ultimate truth. Do you really think you do? How would you know you do?I did not claim that it needed to be improved, I'm pointing out that it wasn't a case of people accepting it without question.
Can you improve the Scientific Method? Without adding unnecessary steps?
The Scientific Method is the simplest it can be without people ending up becoming paranoid and cross-checking everything ad infinitum.
What does the Newton-Raphson Method do? How does it do that?æðрь áûðòÑÂý said:Your point being?It works like the Newton-Raphson Method.
So you keep repeating...æðрь áûðòÑÂý said:I don't care whose fault is it! The scientific method is not working itself! Its the people who are using it! And they are failable!That is the fault of the individual - not the Scientific Method.
Peer-review is meant to catch that failure - it may not always work, but it does act as a safety-net to prevent bad science from occurring.
Only through the Scientific Method can we make steady but certain progress.
There's nothing else that'll allow us to progress.
Prevarication.æðрь áûðòÑÂý said:It uses peer review, that's my point.http://en.wikipedia.org/wiki/Sokal_affair
That was not what you implied - nor intended.
As I, and others, have already pointed out, it had nothing to do with the Scientific Method - nor peer-review related to scientific theories or experimental results.

Unlike Science.
As I've just pointed out, it's not!æðрь áûðòÑÂý said:Its the same thing.The peer-review process for Science papers is not at all the same as those for the Humanities!
You're still obsessing about this - something to which borrofburi alluded earlier: The Relativity of Wrong.æðрь áûðòÑÂý said:Less likely still means failable.But less likely so!
Thank you for agreeing with me...æðрь áûðòÑÂý said:True,It gives us models which work better than others - over time - and the less-workable and/or invalid models are discarded.
Which I've never claimed it to do - not "the truth", just "a better truth"æðрь áûðòÑÂý said:and this process still does not give you the truth.
As I've already pointed out.
As I've already implied - the Newton-Raphson Method.æðрь áûðòÑÂý said:Just better and better models.
But not when you leave the Earth.æðрь áûðòÑÂý said:Its still in use as I provided evidence for earlier. The ECI and ECEF reference frames are geocentric.Like geocentricism.
And yet you've been trying to prove that Science is wrong about physics here (the aether, heliocentrism, etc) - and biology (evolution) in the other thread...æðрь áûðòÑÂý said:Which they are. But that does not mean I do not accept them.You have dismissed the Scientific Method, Science and Mathematics as "failable" [sic]
Then, you can't make any sort of progress.æðрь áûðòÑÂý said:I don't!If you have no trust in these to discern objective reality from subjective illusion, how can you expect to find out what's true?
Still obsessed!!æðрь áûðòÑÂý said:And what you got with that process is still an incomplete model. Thus NOT the truth.Models (hypotheses/theories) are tested against the real world through experiment - if they fail that test, they are discarded for those models that reflect the real world. That are workable - which can be used to make predictions about what one will find before one tests it against the real world, again.
You appear to suffer from what's called "Man's need for certainty in a uncertain world".
Life - Nature - is not a zero-sum game, it's not "all-or-nothing".
The fact that a relative truth works in "the real world" is better than something which doesn't - and the fact that it does work is a fair indication that we're, at least, half-way there.æðрь áûðòÑÂý said:Yes, precisely my point. It does not give you absolute truth. And this relative truth of yours is still not any colser to real truth, since you don't know what the truth is,s o you don't know how close you are to the real truth.Yes - it may not give you ABSOLUTE truth - but it gives a more accurate RELATIVE truth than previous models.
Geocentric - but not used off-Earth, as I've explained above.æðрь áûðòÑÂý said:This is simply not true. ECI and ECEF are geocentric models.Hence, why Science uses the heliocentric model, rather than either of the other two.
Not all of them do so in the geocentric model!!æðрь áûðòÑÂý said:Wrong. The planets are going around the Sun too!No, it doesn't!
The heliocentric model has the planets going round the Sun - the Tychonic model has the Sun and the other planets going round the Earth. With circular orbits.
It gives distances in terms of Earth and Moon radii - there's a table towards the end comparing the reconstructed and modern values. You should already know what these are.æðрь áûðòÑÂý said:This article doesn't give out any numbers on how exactly far the Moon and the Sun are.Aristarchus On the Sizes and Distances [of the Sun and Moon]
We've shown you throughout - but see the Ulysses Mission above.æðрь áûðòÑÂý said:Show me one evidence.It does - all observable evidence, from astronomical observations and probe/satellite mission data confirms this.
As explained earlier, they wouldn't - due to the mechanics of the Solar System: predominantly, the Sun's gravitational field.æðрь áûðòÑÂý said:That doesn't meant that they couldn't do teh same with the geocentric model.The mission data is - along with the fact that the probes arrive at their destination safely based on the heliocentric model.
Not account for them!!æðрь áûðòÑÂý said:What exactly didn't the geocentric model do?Because the heliocentric model had accounted for them - by virtue of it working! Unlike the geocentric one.
The problem here, as I've pointed out, is his assumption about the Earth being flat.æðрь áûðòÑÂý said:Well I did it for him.He based it on the assumption of a flat Earth - hence, he only took a 400 mile baseline.
If he'd based it on a spherical Earth, he'd have realized he had to take into account the proper value of the Earth's radius - and he'd have gotten a far more accurate result!
The left part of the picture shows you the Earth. From the top to the bottom is the distance half of the equator which is 24,860 miles, so the half distance is 12,430. Thus 90,°is then a quarter, which is 6,215 miles. And thus, to make it short, we get to 400 miles distance that Rowbotham used. From the top of teh Earth, which is 0, to 400 miles is about 6,°. So to get the better approximation for a spherical Earth we need to add 6,°to Rowbotham's measurements.
Now on to the right side of the picture. The original Rowbotham's measurement had this same picutre, which had the distance to the Sun split up in 14 equal parts. Which are the same as 400 miles. If we now rotate the observed right line of light to the right for 6,°, we get the height of the sun at 18,6 parts. Which equals 531 miles.
Thus, according to Rowbotham's method, the Sun is about 531 miles above the Earth.
Given that the Earth is, in fact, round (an oblate sphere, to be precise), not only is his calculation wrong - but the manner in which he applied the formula.
There are other problems with his approach:
He assumes that the Bedford Levels were ... level - even though he states that there was a flow of water, which indicates that they're not.
He was looking "up-slope", which would add to the "height" of the horizon.
Worst of all, he seems to have been unaware of Aristarchus' attempt to measure the distance of the Earth from the Sun - Aristarchus was unable to measure the angle the Sun made (it's virtually 90 degress) which would have given Rowbottham some idea of how far wrong he was!
Again, thank you for agreeing with me...æðрь áûðòÑÂý said:Okay,We do know - shining them through media tends to affect them, From which, you can deduce what effects the media are having and correct for that.
This is what's done with the "twinkling" effect of starlight passing through the atmosphere and detected by telescopes - astronomers correct for this to get a clearer image of the star.
Still obsessing!!æðрь áûðòÑÂý said:but you don't know what else could affect those measurements.
Actually, you're the one who's been banging on about people, Science, the Scientific Method, Mathematics, etc, being "failable" sic.æðрь áûðòÑÂý said:You said that people are failable right?Where did I say this??
It is you who has been claiming this throughout my discussion with you!!
All I said was that the Scientific Method is used to discern whether a observed phenomenon was in our head or external to us - to ensure that errors weren't made in observation or experimental results.
Kindest regards,
James
