We will see and hear the term Darwinism a lot during 2009, a year during which scientists, teachers, and others who delight in the accomplishments of modern biology will commemorate the 200th anniversary of Darwins birth and the 150th anniversary of the publication of On the Origin of Species. But what does Darwinism mean? And how is it used? At best, the phrase is ambiguous and misleading about science. At worst, its use echoes a creationist strategy to demonize evolution.
snip...
In summary, then, Darwinism is an ambiguous term that impairs communication even about Darwins own ideas. It fails to convey the full panoply of modern evolutionary biology accurately, and it fosters the inaccurate perception that the field stagnated for 150 years after Darwins day. Moreover, creationists use Darwinism to frame evolutionary biology as an ism or ideology, and the public understanding of evolution and science suffers as a result. True, in science, we do not shape our research because of what creationists claim about our subject matter. But when we are in the classroom or otherwise dealing with the public understanding of science, it is entirely appropriate to consider whether what we say may be misunderstood. We cannot expect to change preconceptions if we are not willing to avoid exacerbating them. A first step is eschewing the careless use of Darwinism.

I can't imagine why you would think I would be interested in this info. I am not waiting expectantly for your return nor do I care what you and your wife do. You seemed to indicate that the timing of another poster's response was important (post 423)...
The last FReeper who was this irascible on a regular basis was RightWingProfessor (banned or opused, I'm not sure; he's now on Darwin Central).
Many posters exchange light pleasantries of this type over the course of a thread; maybe you're not used to it.
Cheers!

To: GourmetDan
No one ever said that the CS of geocentrism and geokineticism were shown to be either true or false. What is being said is that they are equivalent and there is no observational or physical way of distinguishing between them. The fact is that it could equally mean that the earth is not moving. Correct. It is called the equivalence principle. You can arbitrarily pick any point and call it fixed.
Also, saying there is 'no absolute frame of reference' is an assumption of GR not a demonstrated fact
Correct, science has no facts, just evidence.
And, GR does not require that the speed of light be fixed across time, only that it be the same throughout the entire universe at any point in time. That is a huge difference in meaning. If the speed of light is not fixed across time, then time and distance are not variables.
No, even if the speed of light isn't the same at all times, time and distance are still variables. You have just added a third variable.
If you performed an experiment to detect the assumed motion of the earth about the sun, found no sign of said motion and then developed a theory that assumed that motion but had to be consistent with no evidence for it, you would have GR.
You will have to explain yourself a little more. I have no idea about what you are trying to say.
And again, let's not assume that ease of use represents reality because then you would have one reality within the earth-moon system and an opposite reality within the solar-system. That you choose to believe the solar-system CS is a philosophical choice, nothing more.
A philosophical Choice? It depends on what you are studying or attempting to do. If you are planning a trip to the moon, you can use the Earth as a fixed reference point. If you are studying the planets it makes sense to use the Sun as a reference point. If you are studying the stars it makes sense to use the stars as a reference point. It is all relative.
That's what Ellis was saying.
I don't know who Ellis is.
What you guys fail to understand is that a huge number of things you accept as fact, are not.
There are no facts, just theory and evidence. Find some evidence to contradict the theories and you will invalidate them. That is science in a nut shell.

To: mrjesse
But when there is a third body in motion (for example, light) then we can measure and calculate angles and distances between all three -- and now being orbited and spinning are no longer indistinguishable. Light is not a third body, that was Einsteins point. You can't use light to determine your absolute velocity, there is no aether (or fixed velocity for that matter). Did you miss my example of the people floating in space with radar guns?
The use of a third body for reference only changes the point of reference, which can be very helpful and it can simply be an arbitrary point, it doesn't have to be a 'body'. Did you not look at the Merry go Round animation that I linked to?

To: LeGrande
Said LeGrande:
Light is not a third body,...
Now wait a second! You previously
said "Light, is the moving part in the LRG" ! Early on in the discussion when you said that there was no difference between spinning and being orbited in a two body model I said "But if you bury a Laser Ring Gyro 10 feet deep on earth it'll tell you whether you're spinning or being orbited" and you
said "The Gyro, LRG and pendulum are essentially the same thing and if you add them in you are adding in a third body and unnecessarily complicating the model."
And now you say that light is not a third body? Did you change your mind? or what? You, my friend, have contradicted yourself most brilliantly this time, have you not?!
I did see your example the people floating in space with radar guns but that's not an angular equation, which the lag of the sun is. I also saw your example of the merry go around and the football players (or whatever those creatures were.) They demonstrated 3 bodies in motion - the ground, the go around, and the ball. And it was obviously absurd to say that the merry go around was being orbited because look at the spiral the ball took! I mean maybe it was a foot ball, and I know they don't bounce nicely and they may not fly straight, but they don't fly that badly in a spiral!
The question at hand is not about frames of reference but whether, for an observer on earth, at a point in time, the sun appears 2.1 degrees behind its actual position or Pluto 102 degrees or a 12-light-hour planet, 180 degrees, or if an observer on the north pole on a merry go around turning at the rate of 180 degrees per 8.3 minutes would see the sun appear in one direction while its actual and gravitational position were the exact opposite direction -- all, of course, at an instant in time.
And since we're discussing the earth, the sun, and the light that travels from the latter to the former on a course reasonably uninfluenced but either the sun or the earth, we must consider there to be 3 bodies in motion if we are to be able to discuss how far lagged the sun might or might not appear to be.
By the way, if you still think that "appear" and "see" are the same thing, here's an illustration that shows the difference:
Let's say I reported to you that "I saw a man coming out of a bank with a mask on and his pockets full of money. It appeared that he had robbed the bank."
See difference? What I saw was certain fact - I
did see the man and so on and so forth in this example. Now whether he actually had indeed robbed the bank or not I do not know, only that in my judgment it appears that he had robbed the bank. But it could be that he just likes masks and had withdrawn money from his account.
To take it further, if I had then called the police and said "I saw a man rob a bank" or "I see a man who robbed a bank" I'd be lying since I didn't see it, and didn't even know for certain that he did rob the bank. The only honest thing I can say is that I saw him, and it appeared to me that he had robbed the bank.
Does that help?

The Red question - 12 light hour away planet:
For an observer on earth who is looking at a bright and stationary planet that is 12 light hours away and is above the earth's equator, at the instant that said planet appears in the east will it really be in the west? Will its gravity be pulling in the opposite direction of where the light appears to come from at that instant? LeGrande's Answer: None yet to this question. |
The Green question: Pluto
For an observer on earth who looks up and sees Pluto when it is overhead and when it is 6.8 light hours away, at that instant in time, will Pluto really be about 102 degrees away from where it appears? Will it really appear directly overhead at the moment it is really below the horizon? LeGrande's Answer: None yet to this question. |
The Blue question: if the sun were 10 light days away
If the sun were 10 light days away, and the earth was suddenly stopped, do you believe that the sun would continue to appear to rise and set for another 10 days? LeGrande's Answer: None yet to this question. |
The Yellow question: Turntable at north pole tracking the sun
Let's say that you are standing on a turntable at the North Pole. Lets also say that the turntable (and its pointer) is tracking and pointing at the Suns gravity field (its actual position). Will the pointer on the turntable be pointing at* the light that you see or will it be leading or lagging that light by 2.1 degrees? (*Note: by "at" I mean "within about 20 arcseconds") LeGrande's Answer: None yet to this question. |
The Lavender question: 17 minute merry go around tilted toward Polaris
Let us say that I tilted up my merry go around so that it's top pointed directly at the north star (Polaris to be specific) and furthermore let us say that I got it spinning at exactly 180 degrees per 8.3 minutes with reference to the position of the sun -- at the instant that the sun appeared almost exactly in my face, would it really be behind my head? In other words, would the light be coming from about the exact opposite direction from where the sun's gravity would be pulling - at any instant in time? LeGrande's Answer: Just asked, Awaiting answer.... |
The Purple question: 17 minute merry go around on north pole
Let us say that I had a merry go around on the North Pole furthermore let us say that I got it spinning at exactly 180 degrees per 8.3 minutes with reference to the position of the sun -- at the instant that the sun appeared almost exactly in my face, would it really be behind my head? In other words, would the light be coming from about the exact opposite direction from where the sun's gravity would be pulling - at any instant in time? LeGrande's Answer: No answer yet. |
The Aqua question: 17 minute day vs 17 minute merry go around revolution.
You said that If the earth were turning at the rate of 180 degrees per 8.5 minutes, the sun's optical image would be lagged 180 degrees from its real position.
But then you say that if I was on a merry go around that was turning at the rate of 180 degrees per 8.3 minutes, and the sun appeared on the horizon, the sun's apparent position would not be 180 degrees displaced from its actual position.
So how come, by your theory, would the earth's hypothetical rotational rate of 180 degrees per 8.3 minutes, for an observer on earth at an instant in time, cause the sun's gravitational pull and light to come from opposite directions from eachother, when for an observer on a merry go around turning at the same rate, it would not? LeGrande's Answer: None yet. |

PS. Sorry.
Said LeGrande:

But you
can use light to determine your absolute
angular velocity! That's why the Laser Ring Gyro works. And that's why Foucault and Michelson were able to use the spinning mirror
method.
So can you at least give me one good reason why you won't answer any of my color-coded questions?

Resorting to a personal attack so soon? Come now, you said that you are in the habit of thanking people when they show you were your errors reside, didn't you? You should thank me for showing you where your error really is. It's in your brain. Lodged like a maggot. Mrjesse has been trying to remove it, but you are an uncooperative patient.
To: mrjesse
But you can use light to determine your absolute angular velocity! No you can't. There are no absolute velocities. All velocities are a relation to something else and light can't be that something else.
But you can use light to determine your absolute angular velocity! That's why the Laser Ring Gyro works. And that's why Foucault and Michelson were able to use the spinning mirror method.
What result do you get with your laser ring gyro on the equator? It tells you nothing, the point you seem to miss is that the laser ring gyro is a third body that you are referencing from, just like my example of the two men floating in space with a spaceship. If you assume that the spaceship is stationary, then you can determine the velocities and directions of the men with respect to the spaceship. The laser ring gyro is no more fixed than the spaceship.
So can you at least give me one good reason why you won't answer any of my color-coded questions?
I have answered those questions. You can answer those questions yourself if you can figure out what your reference frame is and what you mean by an 'instant' in time? When the light leaves the object or when the light is seen by the observer. You don't seem to understand that when you are looking at something you are seeing into the past.
There is no universal 'now'. Time and distance are variables. You should read up on the Michelson-Morley experiment, they tried to use light to determine the Earths velocity and failed. If you were correct that light can determine absolute angular velocity, Michelson and Morley would have succeeded : )

Replied LeGrande: No you can't. There are no absolute velocities. All velocities are a relation to something else and light can't be that something else.
Are you quibbling over the fact that I said "absolute angular velocity" rather then "absolute angular rate?" If there is no such thing as an absolute angular rate then how do you explain a gyro? Even a simple spinning weight works as a gyro. You know that! You're a pilot after all! Does your
artificial horizon or your
turn rate coordinator or your
Gyro compass/heading indicator not work on the basis of absolute angular rate? Ever heard of
Foucault's pendulum experiment?
What result do you get with your laser ring gyro on the equator? It tells you nothing,
Huh? A laser ring gyro works just fine to measure earth's rotation on the equator just like any other absolute reading gryo -- assuming of course you have the gyro oriented in the correct way to measure the rotation of the earth...! Do you really think that a top like
this wouldn't work on the equator? Are you smoking varius weeds? [grin]
the point you seem to miss is that the laser ring gyro is a third body that you are referencing from, ..... The laser ring gyro is no more fixed than the spaceship.
Then how does the ring laser gyro know that the earth is rotating at about 360 degrees per 24 hours even when buried 10 feet deep? Don't you mean that the light inside the LRG is a third body, not the hardware part of the unit?
And you just got done
saying that "Light is not a third body"!
I don't know if you knew this or not, but if you bury a ring laser gyro (or any good gyro for that matter) in the correct orientation, it will measure the earth's rotation. Now it has no idea where the sun is, or anything else - all it knows is that it's rotating -- and what, I ask you, is it basing its measurement off if not absolute angular velocity of zero?
I have answered those questions.
Yeah, yeah, you keep saying that. And I'm well aware that you've answered many questions that I didn't ask, even if they sounded similar. But if you answered the questions I asked, I sure don't remember it! And I also don't remember you ever providing links and saying to me "Here is where I answered that one."
But in any case, if you have already answered them, then would you please be so kind to answer them now as well? They are simple easy questions with short answers; it won't require a lot of thought or typing on your part. If you already answered them then you have nothing to fear from answering them again! (except of course, if you haven't answered them already, then I can see why you won't answer them now.)
You can answer those questions yourself if you can figure out what your reference frame is and what you mean by an 'instant' in time?
Oh I already answered them for myself -- but I came to the opposite conclusion that I expect you will. And I don't know if you know this, but in science, there are times when a measure can be taken of the angle between two things at an instant in time. For example, 2 cars are traveling the same speed down the road. How far apart are they? 20 feet. That 20 feet measurement is a valid measurement and is still valid even though now "frame of reference" was defined - well, actually, the frame of reference was defined - it was the distance of one car in a frame of reference of the other car - in other words, the distance between them, referenced to each other. And this is the same thing with my question, and this is why it is valid of me to ask you about the apparent displacement of the sun from its actual position - at an instant in time because the question is not one of rate but one of angular difference. And I don't know if you knew this, but it is possible for two things to have an angular difference at an instant in time.
When the light leaves the object or when the light is seen by the observer. You don't seem to understand that when you are looking at something you are seeing into the past.
Of course I understand that -- but you seem to not understand that the light's record of the sun is still true even though the record is 8.3 minutes old, because the sun hasn't moved since the record was made.
There is no universal 'now'. Time and distance are variables.
You're totally missing it! Back to my example of two cars which are both moving at the same rate: If they are moving at the same rate (and direction), then the distance between them will remain constant! so once we know them to be moving at the same rate, it is then valid to ask "What is the difference between them at any instant in time." -- Just like it is valid to ask regarding the 2.1 degrees or the 102 degrees for Pluto or the 180 degrees for the 17 minute day or whatever -- because since the sun moves at the same rate as it appears to move, it is therefore valid to ask about the angular difference at any point in time.
You should read up on the Michelson-Morley experiment, they tried to use light to determine the Earths velocity and failed. If you were correct that light can determine absolute angular velocity, Michelson and Morley would have succeeded : )
But Michelson
did succeed in measuring absolute angular velocity! It was called
the Michelson-Gale-Pearson experiment!
That's what I've been telling you all along! While light may not work to measure absolute linear velocity, it can be used to measure absolute angular velocity - and as a matter of fact is used for just that in laser ring gyros today!

Quote "When a Foucault pendulum is suspended on the equator, the plane of oscillation remains fixed relative to Earth... the angular speed, α (measured in clockwise degrees per sidereal day), is proportional to the sine of the latitude."

Notice that they say that the plane of oscillation is the reference point, not that the plane of reference is fixed.

LOL No I didn't know it because it isn't true : ) It is just as valid to say that Foucault's pendulum is rotating and the Earth is fixed. It is only when you add a third point of reference (like the stars, or sun) that you can say that the an object is moving (rotating or otherwise) with respect to that reference.
Oh I already answered them for myself -- but I came to the opposite conclusion that I expect you will.

Take another look at the Merry Go Round, and visualize the ball as a photon. Notice that both observers are facing each other when the photon is emitted and when the photon is received, the person on the Merry go Round has his back to the receiver.
Which 'point in time' is the correct reference? When the photon is emitted (the observers are facing each other) or when the photon is seen (both observers are facing the same direction,180 degrees difference)? This is exactly the answer to your 12 light hour question.
You're totally missing it! Back to my example of two cars which are both moving at the same rate: If they are moving at the same rate (and direction), then the distance between them will remain constant! so once we know them to be moving at the same rate, it is then valid to ask "What is the difference between them at any instant in time."
No, I understand exactly what you are trying to say. Your problem is that you are implicitly using the Earth as your frame of reference for the two vehicles. If you eliminate the earth as your frame of reference then the vehicles are not moving at all.

Oh, this is starting to get fun!

You think I could sell some one Ebay and have plenty left over, huh? [grin]

Replied LeGrande: Quote "When a Foucault pendulum is suspended on the equator, the plane of oscillation remains fixed relative to Earth... the angular speed, α (measured in clockwise degrees per sidereal day), is proportional to the sine of the latitude." Wiki Foucault pendulum.
Like I pointed out (See bold above) if you are going to try to measure the absolute rotation of the earth, and you have only a 1 axis gyro, you have to align that axis with the earth's rotation - just like using a tape measure - you can't measure the length of something by having the tape measure crosswise.
I guess you didn't know this, but the Foucault pendulum is a single axis gyro, and due to the construction thereof, its axis of measurement works best on the poles and not at all on the equator. But there are lots of other gyros which can be operated in any orientation (like those in airplanes, flywheel gyros and laser ring gyros) which can detect and measure the earth's rotation even on the equator, simply by starting out the gyro with it's axle pointing either up or down or east or west. (or any direction not north and south.)
So it is most absurd for you to say that since the Foucault pendulum doesn't work on the equator that therefore no type of gyro works on the equator -- because not all gyros are constructed in such a way that their operation is limited to a certain orientation.
So on the poles, you could measure the absolute angular rate/velocity of the earth with a Foucault pendulum. Using a correctly oriented gyro of other types (like spinning flywheel, laser ring gyro) you can measure absolute angular rate of the earth at any point in or on the earth.
And do you notice that they mention "sidereal day?" Do you know what that
means? Even the Foucault pendulum measures the absolute angular rate of the earth's rotation - regardless of the sun's position! In other words, the star-referenced direction of the sun changes throughout the year, and yet a good gyro can not only track and measure the earth's rotation each day, but it can also track and measure the earth's rotation of 1 turn per year! And you think there's no such thing as absolute angular rate?
Said MrJesse: I don't know if you knew this or not, but if you bury a ring laser gyro (or any good gyro for that matter) in the correct orientation, it will measure the earth's rotation. Now it has no idea where the sun is, or anything else - all it knows is that it's rotating -- and what, I ask you, is it basing its measurement off if not absolute angular velocity of zero?
Responded LeGrande: LOL No I didn't know it because it isn't true : )
You don't think that a gyro can track the earth's rotation? How about that. Anyway, if you really believe that a correctly oriented gyro of good enough quality cannot track the earth's rotation when placed anywhere on or in the earth, then you should read
this or go search google or go to the library yourself. Trust me - absolute reading gyros can be used to measure the absolute angular rate of the earth!(I mean if you are certain that there is no gyro that can be used to measure the absolute rotational rate of the earth by placing it anywhere on the earth, then you go ahead and provide some evidence or articles to that affect - but I'm telling you, you're wrong. I've provided a link that demonstrates that you are wrong.)
And if you did have a Foucault pendulum on the north pole, just why do you suppose it's turning strangely at the rate of the earth? What gets it spinning, anyway? If the Foucault pendulum is not tracking absolute zero angular rate, then what is it doing and why does it pick that speed?
And if it's not tracking absolute zero angular rate, then what
is it tracking? It's obviously tracking something -- and it's not the sun!.
It is just as valid to say that Foucault's pendulum is rotating and the Earth is fixed. It is only when you add a third point of reference (like the stars, or sun) that you can say that the an object is moving (rotating or otherwise) with respect to that reference.
Sorry dude, I'm not buying your claim when the evidence is to the contrary. The earth could spin at any speed, but it would take force to change its rotational velocity. The gyro goes at zero angular rate as compared to the stars. If you're going to say that that's not absolute zero angular rate then you'd better provide some nice evidence.
Take another look at the Merry Go Round, ...
Sorry, not now. You refuse to answer my color coded questions. And you have contradicted yourself on whether light is or is not a third body. You contradict science when you say that it's not true that a gyro cannot measure the absolute rotational rate of the earth. I've already seen the merry go around and given you my response.
I also know that you keep trying to move this to a discussion of "frame of reference" when the questions I'm asking don't require any such discussion - but that's just another outworking of your desire to change the subject.
Which 'point in time' is the correct reference? When the photon is emitted (the observers are facing each other) or when the photon is seen (both observers are facing the same direction,180 degrees difference)?
You're not getting it, are you. Remember, we are talking about the constant angular displacement between the suns actual and apparent position. Since the distance to the sun is more or less unchanging (close enough for our discussion) and since the apparent rotational rate of the sun (in other words, the rotational rate of the earth) is also reasonably constant, any apparent displacement of the sun will also be constant. Thus, it doesn't matter which point in time - it doesn't matter whether it's yesterday, or tomorrow, the day you were born, or in 50 years - since all the parameters are the same, the apparent angular displacement will be the same - it doesn't matter which point in time. Your football merry go around demo may only send out one photon, but the sun really sends out a constant flood of light.
This is exactly the answer to your 12 light hour question.
Hey, speaking of your merry go around demo, doesn't that prove that if I was on a merry go around turning at the rate of 180 degrees per 8.3 minutes - that the sun would appear in the exact opposite direction of it's gravitational pull?
Said MrJesse:You're totally missing it! Back to my example of two cars which are both moving at the same rate: If they are moving at the same rate (and direction), then the distance between them will remain constant! so once we know them to be moving at the same rate, it is then valid to ask "What is the difference between them at any instant in time."
Replied LeGrande:
No, I understand exactly what you are trying to say. Your problem is that you are implicitly using the Earth as your frame of reference for the two vehicles. If you eliminate the earth as your frame of reference then the vehicles are not moving at all.
How am I implicitly using the earth as a frame of reference? I never said with reference to what they were going x miles per hour. The only frame of reference I gave in an absolute way was that they were both going the same speed and in the same direction one ahead of the other, and that they were a certain distance apart. In other words, my frame of reference was the other car. Same thing goes for the sun and its apparent position: Since the lag (if any) and rates are all constant, the only question left is "How far apart are they."
By the way, you
said "
When someone shows me an error that I have been making, I thank them.". And then you
said "
If you were correct that light can determine absolute angular velocity, Michelson and Morley would have succeeded : )".
Then I
pointed out to you that "Michelson
did succeed in measuring absolute angular velocity! It was called the Michelson-Gale-Pearson experiment!"
As a matter of fact, I've pointed out quite a few points where you've been in error - and I've used sources so you can go read it for yourself! And yet you provide no supporting sources for your claims. In your opinion, have I ever told you something that you didn't already know? Or do you really see yourself as 100% correct in this discussion and me as 100% wrong?
I simply cannot fathom how you can make such claims, and stick behind them for so long (
seven months!) even though we've provided so much scientific material that counters your claims and even though you haven't provided a single scientific material that supports your claims. What's going on? I mean, are you like the brightest person since good old Albert E. ? Are your ideas just such new and amazing that nobody else has ever had them? Unless you are the inventor and pioneer in the field, there has got to be some other scientific writings that support your views. But there sure don't seem to be any!
Is this just a matter of faith for you? You know it must be true so therefore it is? Amazing. How could somebody go on for so long believing something that is scientifically unsupported -- and as a matter of fact, scientifically refuted, unless it is by pure faith? Please help me understand! I mean, just imagine what it'd be like to believe with all your heart in something that you claimed was purely scientific and yet for which you could not present a shred of scientific support or evidence!
Please explain!
Thanks,
-Jesse

Take another look at the Merry Go Round, ... Sorry, not now. You refuse to answer my color coded questions.
The Merry Go Round example answers the color coded questions.
Enjoy : )

"You seemed to indicate that the timing of another poster's response was important (post 423)..." Or maybe you just misunderstood what I was saying. Trust me, I'm not interested in what you and your wife do, how much you enjoy it, where you went to dinner or when you'll reply.
"Many posters exchange light pleasantries of this type over the course of a thread; maybe you're not used to it."
If you think that's 'light pleasantries', I'd hate to see what you consider graphic.

"I don't know who Ellis is." "People need to be aware that there is a range of models that could explain the observations, Ellis argues. For instance, I can construct you a spherically symmetrical universe with Earth at its center, and you cannot disprove it based on observations. Ellis has published a paper on this. You can only exclude it on philosophical grounds. In my view there is absolutely nothing wrong in that. What I want to bring into the open is the fact that we are using philosophical criteria in choosing our models. A lot of cosmology tries to hide that.

Enjoy : )
Ahah! All along you've been saying that you have answered my questions. Now you say that the merry go around example answers them. But the merry go around example doesn't answer my questions! My questions are specific and have answers like "Yes, No," or perhaps some numbers like "180 degrees." So when you say that you answered my questions you really mean just like the merry go around example did -- which is not really! So you haven't answered my questions all this time and you've been saying that you have! But in order for me to know that you really believe your theory, I need you to personally answer my color coded questions specifically.
Look... You've asked me lots of specific questions with numbers or "yes/no" for answer, and I've answered many of them. You well know that science won't get anywhere without answering specific questions.
So when you refuse to actually personally answer my color coded questions, the only conclusion that I can logically come to is that you are outright lying in your claim of 2.1 degrees for an observer on earth at an instant in time, and that you are outright lying in saying that you have answered my questions -- and that you know full well that you're lying.
How can I (or anyone else) logically come to any other conclusion when you refuse to apply your claims to some simple questions?
-Jesse
PS: You still haven't answered my comment about Foucault's pendulum tracking absolute angular rate of zero, or about Michelson detecting the rotational rate of the earth with light. Or for that matter any of the other numerous cases where you've made a scientifically incorrect statement and I've provided evidence to the contrary. Everything together convinces me that you must be knowingly lying. How can I come to any other conclusion? Am I just immeasurably stupid? Sometimes it feels like it. If I was just ignorant, you could just show me the scientific reports which support your claim and then I wouldn't be ignorant about that anymore. But as it is no matter how hard I try, things you say still don't make sense or seem honest.

But as it is no matter how hard I try, things you say still don't make sense or seem honest. I don't think you are stupid. You simply don't have a good grasp of basic concepts. You are correct that many basic concepts don't initially make sense. Anyone dropping a bowling ball and a feather can clearly see that the bowling ball drops faster than the feather, and except for exceptional circumstances, that observation is correct. You seem to be stuck at that point.
It is hard to explain why everything falls at the same rate. We know the answer, but if I tell you the answer, you will think that I am lying : ) because the answer won't make intuitive sense to you.
If you really want to understand reality, it requires that you take a viewpoint different from yourself and your preconceptions. Everyone's preconceptions are wrong, it is impossible to completely understand reality, but the journey is fun : )

It's common courtesy when delaying a reply to mention why; and most people can relate to talk birthday dinners with a spouse.
If you think that's 'light pleasantries', I'd hate to see what you consider graphic.
Maybe you should read some of Laz's posts...
Cheers!
