I answered the question. You are apparently too ignorant to be able to see that.
So, okay, I have given a reworded answer.
Now go learn something about science. Ignorance is temporary; you should be able to overcome it.

It doesn't matter what standards you use, as long as you are consistent. You cannot state the hypothesis in dynes and report the result in newtons, unless you apply the appropriate conversion factor. Regardless of what standard you use, if your methodology was flawless, if your results contradict Newton's laws of motion, and if your results can be replicated, then we must conlcude that Newton was wrong.

Could you please post some links to web sites that directly refer to these 'standards', so that I may understand what you are talking about?

I recommend the CRC Handbook of Chemistry and Physics, but I don't know whether it is available online. There's probably a copy in the reference section of your local library.

I'm going to use the metric system, except I will use local time instead of internationally standardized time. That is, I will take noon to be the time when the sun appears to be at its highest point (or in a direct north/south direction). I will take the time interval between two consecutive noons, and divide that into 24 local hours. I will then further divide those local hours into local minutes and local seconds.
With careful measurement, and using that local time as my standard, I should be able to show that the rotation of the earth is speeding up and slowing down, but there is no known force that would explain such speeding up and slowing down.
Should Newton's laws be rejected, or should my data be rejected?

CS writes:
The point is that F=ma is different from a theory like 'All swans are white' because it doesn't use the same inductive process.
Doesn't it?
I don't think so.
Do you think that the scientific conclusion is that F=ma only applies to those occurrances we have actually observed rather than ALL events where forces apply?
No. F, what that capital letter is representing, equals mass time acceleration. It is defined as that and cannot be anything else.
CS writes:
But the F can't be anything other than the m times the a because that's what it is defined as being.
Can't be?
Correct. Anything else would not be F.
Are you saing that nature cannot be applying forces that are proportional to the mass squared elsewhere in the universe because our theory simply won't allow that to occur?
No. If you had a force that was not equal to mass times acceleration, then you would not have the F.
The alien culture could have their own F2 that was proportional to m2, like I explained in the message you replied to.
CS Do you think nature cares what the standard is or will behave in accordance with this standard just because we have defined it as a standard?
Really!? Of course not. Gawd!
Without induction what reason do you have to expect your standard to apply to anything that has not been directly observed to behave in the standard manner?
This is a totally different subject. As the point is, this isn't an inductive issue.

Re: Universal Principles
Right:
A law describes.
A theory explains
Laws don't grow up to be theories; theories explain laws.

Religious belief does not constitute scientific evidence, nor does it convey scientific knowledge.

I have a copy.
It is almost 3000 pages long.
I can find no reference to the 'standard' you appear to be refering to.
Can you either be more specific about a location in that book or suggest some web-sites.
I would have expected such a widespread term to be mentioned in many places...

Re: Universal Principles
I have a very very old edition (1960s vintage).
There should be a section where it defines physical properties such as force.

Still too vague.
Is there really nowhere on the web that gives a defintion of 'standard' as you are using it?

Re: Universal Principles
Usually "standard" is used for defining particular units of measurement. I'm just using the same idea in a unit free sense. New Cat's Eye seems to be understanding the word in the same sense, so I don't think there is anything particularly confusing about that. If you prefer the word "definition" instead of "standard", that's a different way of saying the same thing. Definitions are standards.

Since F=ma is causing such confusion, how about Newton's 3rd Law of Motion.
quote:
To every action there is always opposed an equal reaction: or the mutual actions of two bodies upon each other are always equal, and directed to contrary parts.
I am sure you wouldn't say that Newton had tested every action.
And surely you wouldn't say that Newton's laws don't apply to future actions.
So, could you please explain how the words 'every' and 'always' can be used without inductive reasoning?

Three Replies
Combining replies to Message 359, Message 360, and Message 361:
Can you give an example of something that you do know?
The Sun rose this morning.
Do you claim to know things you have experienced?
Not all, no.
How do you deductively conclude from a limited set of observations that a conclusion based on those limited set of obsevations applies universally?
You simply make an assumption to close the gap; really, Straggler, the turning of an inductive argument into a deductive one is elementary. Why the difficulty?
In order to see if you can backup your assertion. It seems that you cannot.
I have made no assertions regarding Newton's Laws, so I am not sure what I would be backing up relative to those laws.
Perhaps you can explain specifically how Newton's third law which tells us that ALL forces are the result of interactions was arrived at wholly deductively?
You just make an assumption to close the gap. Newton observed some shit happening; saw it all happened in a certain way; assumed everything worked like the things he saw; concluded everything happened in that same certain way. Elementary, really.
So this axiom of yours which you have repeatedly asserted is "derived from nothing" is actually derived from experience.
Huh? I don't recall saying such a thing; you will have to point out where I did say such a thing.
That it will always apply, as per your "axiom", is thus an inductive conclusion.
Again; how do you figure this from anything I've said? You asked:
"Jon when you wake up tomorrow morning do you think the world and it's workings will show every indication of having continued along the same lines as when you are observing it?"
I replied:
"Of course..."
You concluded:
"So this axiom of yours ... is actually derived from experience."
Somewhere there is a link missing, for you asked me regarding what I thought, and concluded regarding what I experienced. Two entirely different things; you will have to demonstrate your leap from point A to Q. But even if you do that, you'll still have to show me why 'experience' is in no way tied to 'observation', because it still seems to me like you are trying to derive non-observed information from the world by making observations.
You have conceded that your "derived from nothing" axiomatic starting point of your little deductive exercise is in fact derived from experience.
No; I have not. I've made no statements regarding the derivation of my axioms.
Have you ever woken up to observe the world in a state that is inconsistent with it functioning as observed while you were not observing it?
I'm sorry, but that is just stupid. I cannot observe the world and then pretend like my observations are actually not observations and so then conclude that I made an observation about the unobserved world. What folly.
Have you (for example) ever awoken to find that the world appeared to have been on pause during your period of non-observance?
Again, more irrelevant stupidity.
Do you think you ever will?
Why keep asking?

Straggler writes:
What are the missing premises here?
There aren't any.
Then you remain refuted.
Learn to read Straggler. The reason there are no missing premises is because your argument is stupid, circular, contradictory, and pointless: All unobserved things I observe operate identically to all observed things I observe; All (p) that are (~p) are identical to all (p) that are (p). Only you fail to see the absurdity.

So to translate your previous messages:
quote:
Newton's laws are a definition upon which observation is based. As far as I know, he proposed those definitions on theoretical grounds, and then his "limited set of observations" were used to demonstrate the efficacy of his definitions.
Here it becomes clear that you have things back to front.
Newton did not base his observations on his definitions.
He observered the apple falling before describing the apple falling.
quote:
Another method is to define a definition, such that observations are to be made in accordance with that definiton. Then all observations that are made by following that definition will have the appearance of being specific instances of the general statement which is the definition.
I say that Newton was setting definitions. And we are still using some of Newton's definitions even today. The Wikipedia definition of "dyne" is pretty much the restatement of one of Newton's laws in the form of a definition of measurement.
Again, you seem to think that scientists make definitions prior to making observations.
This is not true.
You observe lots of white swans before claiming that all swans are white.
You do not observe lots of white swans because you decided that all swans are white.
