True, my example posts probably weren't the best. But tell me this (near the end of the thread) doesn't sound familiar:
AVOGARDO wrote:If there would be another source of gravitation, it would sum up to a lightly changed pull. The pull of a source of gravitation would increase, the more its source get near to you (or you to it.) Thus you can determine the velocity throug the increasing force of the pull, if you assume, that the source doesn't change its own mass.
Sounds a lot like this?
AVOGARDO wrote:If the ship is travelling to you with a constant velocity, you can calculate this with the increasing gravitation, unless you think, it would loss its own mass while it is flying.
This is a scenario I had already proven false much earlier: "you don't know if it's a big object moving slowly or a small object moving quickly." You need more information than what he gives in the scenario.
Jedi Master Spock wrote:Correct. If you have finely enough tuned gravimeters, or graviton detectors, coupled with sufficient computation, you can determine mass, distance, and velocity.
There's more to it than just that, given that each gravimeter is going to lump everything within detection range into one vector. You'll have a bunch of possible gravity well combinations that could match your readings, and the problem becomes trying to figure out which range of possibilities is close enough and which ranges to ignore.
Jedi Master Spock wrote:The problem is the hyperbole, and the hyperbole is probably why he reacted so strongly. "Astrophysicist" definitely qualifies, but they aren't the only possible expert.
There are very few engineers involved in designing gravimetric sensors, to say the least, so that would not be a very likely expert to stumble upon the scene.
It's quite simple in terms of determinate fact. He made a statement; you blew it out of proportion; he called you on it. The only dishonesty involved there was your exaggeration in the first place.
Hyperbole is not dishonesty, especially when the term "astrophysicist" can be used to describe a "scientist" who is an "accepted expert" on gravitons. (Somehow, I don't think undergrads count as accepted experts.)
My issue with what he said was the construct of "I'll also accept speculation from someone knowledgeable, but he must be a scientist and an accepted expert on gravitons, and he must not be an engineer" is nonsense if accepted at face value. The fact that he went into detail on requirements and made an exclusionary clause is very telling.
In fact, check
this post out:
AVOGARDO wrote:If you claim, that I have ignored or overlooked a scientifical explanation, an explanation which is proved or evidenced and not only a speculation, you have to name it and have to explain, where my thoughts, as I have tried to explain these, infringe such an scientifical explanation.
A claim is no explanation and no argument.
He wants something that has been proven, or has solid evidence behind it. Not speculation. He then made
another post immediately after:
AVOGARDO wrote:I would even accept a speculation from someone, who is very well versed in these subjects.
That person would have to be a scientist and would have to research this subject and must be an accepted expert on this subject.
An engineer would not be such an expert.
But even this person would have to try to explain the reasons for its speculation.
From this context, it's clear that "even" does not refer to including people (as he claimed it did in his later reply), but the only kind of person he'll accept speculation from: a "scientist" who is an "accepted expert" on gravitons.
Jedi Master Spock wrote:From saying he made a mistake to saying he made two mistakes and didn't really mean for it to be taken that way.
He never said he made a second mistake. His response on being called on the inconsistency was this:
AVOGARDO wrote:No, I had difficulties to unterstand you. Maybe, if you quote something, you should do it in a way that you are understandable.
So his story changed to "I didn't understand" when the contradiction was called out.
Also, what I had asked him was very understandable and I quoted him, using the same wording and phrasing he used, so as to be as understandable to him as possible.
Jedi Master Spock wrote:Frankly, I thought it was common knowledge that radio telescopes detect and successfully resolve extraordinarily minute quantity of energies with high resolution - and depending on the precise snowflake, the amount of background radio noise, and the radio telescope involved, it's not too far from dead accurate.
Actually, he's way off. (As was your estimation. Check your math: intensity is reduced by the
square of distance.)
A
3E-6 kg snowflake melting would absorb about 1 J.
With Mars being, at closest,
56,000,000,000 m, the reduced intensity would be 2.5E-23 J/m^2. The
Effelsberg antenna's aperture is 7,854 m^2, so the reduction in energy received (assuming the energy radiated would have reached the antenna in the first place) by the antenna would be 2.0E-19 J.
That's nowhere near comparable to the energy of a snowflake hitting the ground. (1.5E-8 J or so by your estimate of 0.1 m/s.)
(A snowflake melting on the moon would show as a difference of 4E-15 J to the telescope, also not comparable to a snowflake hitting the ground.)
Jedi Master Spock wrote:For the purpose of hyperbole - as I said, noise is a problem for radio telescopes, and since you weren't concerned with the precise numbers - Mars or Moon, does it really matter? - the claim was quite good enough for the purposes of the argument at hand.
He was using it as evidence for his claim. It was fallacious. And considering the differences between a radio telescope and a gravimeter, he's still way off.
Jedi Master Spock wrote:Actually, it does talk about the specific capabilities of that particular array in some detail - from which you could have gathered the capabilities of the radio telescope and much ado about its fantastic resolution. You have to dig deep through the site, and it's hard to find the right bits if you don't understand German well enough to figure out how to navigate the site. Rude of him, yes, and condescending; however, he did provide you with a website containing evidence to substantiate what he was talking about.
The burden of proof was not on us to calculate the answer for him.
Jedi Master Spock wrote:That sort of rude behavior would not be tolerated here, but AFAIK, SDN rules don't disallow condescending rudeness, nor did you invoke it in your explanation.
That's right, it's not against the rules. But when that's the attitude of someone who is breaking the rules, the Senate is not likely to be lenient.
