My Hot Air Challenge

[Belk]

is this a serious question?

No, I think this is another thread where AV plays silly in order to rile people up. As annoying as AV can be he is fairly bright.

Only at the equator during the equinoxes (I think).

. . .Insert your favorite facepalm picture here . . .

They are perpendicular for any level surface everywhere on the globe except right at the poles.

You can't tell us why everything doesn't roll to the bottom of the globe?

 

[AV1611VET]

No matter where you are on earth, the plumb line and the level with a bubble will give you a right angle. They are, after all, both using the same force of gravity, merely in alternate ways.

You're thinking three-dimensionally, aren't you?

Do you suppose we could apply that to the passage in the Bible about the CIRCLE OF THE EARTH?

 

[AV1611VET]

OK Here's a BIBLE question for YOU. The church at Jerusalem wrote a letter to the church at Antioch. They sent it by the hand of Barnabas, Paul, and some others.

Acts 15:30
30 So when they were sent away, they went down to Antioch; and having gathered the congregation together, they delivered the letter.
NASU

Why does it say the went DOWN to Antioch? You look on a map, it clearly goes up on the page.

I couldn't figure that out either, until I read the accusation:

Acts 17:6 And when they found them not, they drew Jason and certain brethren unto the rulers of the city, crying, These that have turned the world upside down are come hither also;

Then I understood.

QV please:

They don't need a compass --- Luke makes this clear ---Where are they now? --- In Galilee.

Now watch this ---Up to Jerusalem?

Galilee, in AD16 was evidently south of Jerusalem, not north of it --- as it is today on a map.

You guys might be hot-shot geologists, but leave cartography to the cartographers, okay?

Notice too, Thaumaturgy, that it says they turned the world UPSIDE DOWN in AD58.

Thus your flip of 778,050 years ago didn't happen --- did it --- or they would have been accusing the Christians of turning the world back to RIGHTSIDE UP.

Is this a trick question?

Let's say the earth was perfectly round, with a polished topography (no mountains and valleys), and you started a huge marble rolling southward.

In the absence of friction, wouldn't that marble keep going until it passed the equator, then eventually slow down and be pulled back up -- going back and forth across the equator until it finally comes to rest?

Why wouldn't it start rolling on its own?

Wait, you think a three dimensional object has less of an "up"-property than two dimensional objects?
Or conversely, that two dimensional objects have more?

That's just silly.

Both of the cases are equally dependent of the definition. Of which I know of two. As it happens, both definitions applies to both cases.

Or do you have some special definition in mind?

 

[AV1611VET]

Um ... Norton's Law of Motion?

An object at rest tends to stay at rest until acted upon.

 

[AV1611VET]

Or do you have some special definition in mind?

Nope.

Just wondering why, if warm air rises, the higher latitudes aren't warmer.

(Unless the air cools as it rises toward the pole.)

He is an attention seeker.

 

[Loudmouth]

An object at rest tends to stay at rest until acted upon.

In this case, gravity is acting on it. You claim that the South Pole is "down". Therefore, the ball should roll from up to down since gravity is acting on it. Everything that is North should start rolling towards the South, right?

Didn't I agree that the ball would roll down (southward)?

Until it rolls past the equator, then it is pulled back up by ... for lack of a better term ... equatorial gravity.

But again, this thread is about air north of the equator being pushed northward as colder, denser air is pulled southward.

 

[Loudmouth]

Didn't I agree that the ball would roll down (southward)?

No. You said it would be sitting still until you pushed it.

Why would you need to push the ball in order to get it moving downhill?

Pull the other one . . .

But again, this thread is about air north of the equator being pushed northward as colder, denser air is pulled southward.

If air is being pushed around in such a way, then why aren't we? Why aren't we all tumbling across the surface of the Earth towards the South pole?

 

[AV1611VET]

I don't think you are.

I see you're a "gamer."

Surely you're not assuming I'm running on artificial intelligence, are you?

Maybe a Turing program gone wild?

Did your programmer accidently put in the line . . .

North=up

Or the additional line

If mouth=open, then insert foot;

 

[AV1611VET]

No. You said it would be sitting still until you pushed it.

Why would you need to push the ball in order to get it moving downhill?

Oh, I see now.

Ya -- good point.

If the gravity was strong enough to overcome ... what's it called? ... rest friction or something?

But for the record, I did stipulate the absence of friction.

So yes, you're correct -- good catch.

Go outside and point straight down. Are you pointing at the South Pole? No. You are pointing at the center of the Earth.

Now, point straight up. Are you pointing at the North pole? No. You are pointing out into space parallel with your down line that went to the center of the Earth. That straight line between your eyes and straight up is the direction that air densities are sorted. Not North to South.

 

[Elendur]

I see you're a "gamer."

Indeed.

Surely you're not assuming I'm running on artificial intelligence, are you?

Maybe a Turing program gone wild?

Nope. I'm contending your claim that you're actually wondering that thing.

Even if you're not running on an artificial intelligence there is nothing stopping you from running on simulated silliness.
