Sure. But that is not why I was judging Out2. I did not say what I said because he didn't "tow the line" or join the crowd. I have no idea whether it was a real dog or not--nor do I frankly care.

It was the WAY he ridiculed Chrisisall. He patronized him and implied Chris is stupid and ignorant, without explaining why. That is not discussing a different opinion. That is bullying, and in my view, trolling.

And Frem, I am disappointed that you would agree with BDM. I thought you would have known me enough by now that I don't jump on people for thinking differently. I DO however, defend my peeps when they get jumped on for no reason.

I don't have a problem with divergent opinions. I only have a problem with people being mean about whatever opinion they have (mainstream or maverick). And if you don't know that by now, then you don't really know me at all. But then, maybe I shouldn't expect that. I'm just a name on a black and yellow discussion board.

Thanks Kirkules. If Out2 weren't such an ass, he could have explained it to Chris this way to make his point, instead of the old "You flunked physics, didn't you?" I appreciate your taking the time to do this.

As I understand it, the point of contention is assumption of equal initial force. That is, Chris is saying a heavier puppy would have less initial velocity, and a lighter puppy more initial velocity. Of course, without knowing the difference between the initial velocities (if there is actually a difference), it is hard to say off the cuff whether the heavier puppy would still have the greater ending velocity.

I'll write more in the morning.

Let's review just a little...

First , C-I-A made a couple of posts in response to P-N's thread...

In which , he straddled a fence , in an effort to have his 'opinions' heard on both sides of an issue...He postulated a number of his assumptions in an effort to bolster his 'opinions'...

I haveen't a particular regard for 'opinions' in most cases in which mathematical 'proofs' are actually available , but that's just part of the scientific method , perhaps...But , neither had I suggested any math , yet , and as I recall , I still haven't suggested anyone take up the math...

I offered him some search terms so he'd be able to begin correcting *his own* misconceptions about the physics...But he insisted that I explain everything , in other words , act as his free tutor in physics...He rejected my suggestions to just look up the words...

In science , we'd have to come to some agreement about the definitions of the words that describe the things we're talking about...

Agreement on words like the search terms he was offered for his , and my , starting point...
Get on 'the same page' , one might say...But , he said that *I* just wanted a fight...

Who can offer *reason* to someone like that...

What followed , rather than his own sincere search of the relevant areas , was his efforts to out-type me , and the sarcasm about 'inertia' , followed immediately thereby with his ad hominem attacks...

If he'd gone and done some looking into the matter on his own , then he might've discovered that it wouldn't be as easy as he apparently believed , just because he'd stated that I should be able to explain it in only a few sentences . He would've then possibly realized that physics , which he possibly might've figured he must already know , would be perhaps somewhat more complicated...

But , hey , I'd thrown him a lifeline already...

Should we perhaps begin a list of all the things I've been called since this whole matter began ?

Seems a truism , yes , indeed , that some of the 'animals' ARE 'more equal' than others...

Rather than go away and begin his own 'education' , while things had not yet gotten too far out of hand , he continually clung to his assumptions that he must be the correct one , much like a drowning man grasping at straws , without apparently ever realizing that he had perhaps jumped into something over his head , with both feet going first...

At that point , I'm not going to jump in and try to 'save' him ', because , firstly , he didn't actually want to be saved , and secondly , he had begun taking me to task for his own faulty judgment...And thirdly , he continued to waste his 'breath' , so to speak , by continuing to hurl invective at me , flailing his arms against the keyboard , as it were...

Troll , ass , bully...Just your opinions , is all..

Not 'science'...Only an emotional response...

My observation that he'd possibly flunked physics was just summarily denied...Though I phrased it in the form of a question , he was given a *red-light-in-the-brainpan* opporunity for self-correction...

I'm told that in Mandarin Chinese , the word (or character) for 'crisis' has a duality to it , that it consists of two components , one of which means 'danger' , and the other of which means 'opportunity'...

Perhaps my challenge put him in 'crisis' , and while he perceived 'danger' , he did not avail himself of 'opportunity'...

Even if this WERE a case in which mathematical proof is available, opinions are still necessary in discussing assumptions behind the proof. But there ISN'T enough information in this video for any mathematical proofs. You have no idea what the mass is, what the initial force applied is, what the initial velocity is, what the trajectory is, what the induced drag is as the puppy turned in the air, etc. But there isn't any proof, so opinions matter even more. If you had a counter opinion, or if you did have mathematical proof, deliver those--not insults.

Quote:

What misconceptions about physics? He made observations and proposed a hypothesis to explain the observations. If either his observations and/or his hypotheses are wrong or ill-conceived, you could have presented your counter-opinion straight up. Instead you told him to "go back to school" as it were--which only serves to belittle, not make a case.

And I looked up momentum, laws of motion, acceleration, and centripetal force in Wikipedia and that link you eventually shared. None of those definitions, as presented by wikipedia, has any significant bearing on Chris' observations or hypothesis.

Momentum: All things being equal, a heavier puppy has more momentum, and can travel faster than a lighter puppy. But all things are not equal, including initial force applied and initial velocity achieved--which was Chris' argument. So you have no idea what velocity was and what the momentum would have been.

Laws of motion: Neither inertia nor reciprocity of action is relevant. (Yes, we know the puppy will keep moving until something slows it down. And yes, we know something will slow it down. But tells us nothing about the weight of the puppy without knowing initial velocity.) That leaves acceleration, which we can address next.

Acceleration: I only watched the video once, so I could be wrong here. But it seemed to me the trajectory of the puppy was in a largely horizontal arc, with almost no straight vertical drop at the end. As soon as the puppy left the hand of the soldier, there was no longer any force being applied. The puppy would have simply lost velocity, not gained. I would disagree with Chris there was acceleration to begin with, except for the very small vertical drop at the end.

Centripetal force: The radius was the length of the soldiers arm. The puppy was hurled many times more that length. For most of the puppy's path, the difference made by mass in centripetal force would be insignificant. Again, what matters is the initifal velocity, which we do not know. So centripetal force, as I see it, is neither here nor there.

None of these terms are relevant in either supporting or refuting Chris' position. Ultimately, in my view, the video does not provide enough mathematical information to guess the weight of the puppy. It is not something that can be either asserted or refuted as a matter of fact or definition.

I may be wrong, and am open to correction. But there had better be an argument involved and not just arrogant, patronizing insults about intellectual or academic failures.

/B]



Here you go , Ms. C-T-S !

Back in the beginning , before I made any observations or comments at all in this thread...


Let's see , how did that 'reasoning' go :

If that puppy weighs what a 'smallish' cat *did*...

Tell us what the smallish cat *did* weigh...

Can someone quantify what the smallish cat *did* weigh ? There'd be a *start* at working out this little problem...

...the toss "at that speed" ...

At that speed...What is *that speed* ?

Quantify , Please !

OK...So nobody steps up to quantify , once again...

But , despite the lack of *known* quantities...

The 'Conclusion' is that *that speed* is 'impossible' !Due to what ?

Its WEIGHT ! Its UN-known UN-QUANTIFIED Weight !

OF COURSE !

Ergo , UNKNOWN , UNQUANTIFIED , 'WEIGHT' * UNKNOWN , UNQUANTIFIED , 'IMPOSSIBLE' 'speed' EQUALS

ONLY 'stuffed' dog WEIGHING UN-Quantified 'very little' could

ACCELERATE , UN-Quantified *LIKE THAT* ,

GIVEN ,

the 'SCRUFF-OF-THE-NECK* 'hold' ,

PLUS , *UN-QUANTIFIED , UN-EXPLAINED*,

'motion' =
'too fast' = IT DOESN'T

'REALLY'

'WEIGH'

'ANYTHING'....

Does that seem more clear to ANYONE ?

Does that seem 'right to you ? Am I A-Lyin' ?

Hello , 'anybody' ?


Can it get plainer than that ?

Who's doing pseudo-science now ?

Was there something in that 'FORMULA' that escaped everyone's notice , perhaps ?

When these certain Falsehoods are given as Assumptions , can this physics/math problem actually be worked out ?

Can True Results be acheived ? Better than the ones shown?...

Any Takers ?

C-T-S , do you wanna teach this class ?

C-I-ALL , do you ?

That's just it. Chris can't quantify the variables. But then neither can you. So there is insufficient information to arrive at any conclusion, mathematically speaking.

If you had made THAT argument to begin with, instead of the derisive remark about academic failures, we would not have any conflict now.

EXACTLY the point of my CHALLENGE to his ASSUMPTIONS...

So there is insufficient information to arrive at any conclusion, mathematically speaking... ALSO TRUE ! NEVERTHELESS , he made a CONCLUSION , actually many more than just the one...See , so far you and I don't disagree on any particular points , except for the name-calling that was launched early on...You went there , too , all over me , so please don't start preaching to me about it...

If you had made THAT argument to begin with, instead of the derisive remark about academic failures, we would not have any conflict now.

Hey , he had already made all his assumptions and conclusions without a well-reasoned SCIENTIFIC thought process , and a 'workable' HYPOTHESIS ! ...: that COULD have switched on the RED LIGHTS for him...And which might've told him :

STOP ! DANGER/OPPORTUNITY ! NOT ENOUGH INFORMATION ! Garbage In , Garbage Out !

I DID direct him to a place to BEGIN ! And , I did tell him that if he did not BEGIN with an understanding of the 'basic-basics', that there'd be NO WAY to 'do the math' , knowing at that point myself , that he'd already had an 'academic failure'...

Most authorities in Education would certainly concur , that if he doesn't bother to 'go to school' , or crack a book ,
that he'd have an 'academic failure' !

That he'd end up like Jayne Cobb and try to just muscle his way through people , rather than being able to know how to 'get along' with folk...I told him that if he needed 'educating' , he'd have to get it himself...STILL TRUE ! Not doing so was HIS academic failure , because , ironically enough , I didn't feel like it was 'my dog' in that fight..

Chris made ALL the initial (and Inertial) assumptions in that academic failure...The lessons have just been handed to him over and over , by many contributors , and he may not ever LEARN from those academic failures...I truly hope he chooses a different path for his future , and doesn't have his mind snap shut due to a slight challenge , anymore...

Like I told him , it wasn't MY job...That has to all be on him...Sorry !

Again , his CHOICE from the outset !

" Begin at the Beginning ! Begin with THE END in mind ! " --Steve Covey

We still have a ways to go in agreeing on definitions , even the ones that you looked up .

While I applaud your effort at finding 'common ground' with me , there are still some of those definitions for which we've not Begun to find consensus...That would be the next set of points that we'd have to subject to debate...No more name-calling , please...It's tiresome , and not provably true...

Keep the Shiny side up


Anyone with any experience in movies will tell you that was not a live puppy being thrown off a cliff. It was a professional stunt-cat in a puppy suit. Note how you can not see the stunt-cat land on the giant airbag due to clever use of camera angles. The puppy's yelp was of course a stock sound effect added in post-production.

Agreed, but I am glad to see that the public has such a positive view of our service men; holding them to a higher standard then most. I'd prefer that to the idea that they were all fools and psychos. Reminds me of a Rudyard Kipling Poem, to be honest;

We aren't no thin red 'eroes, nor we aren't no blackguards too,
But single men in barricks, most remarkable like you;
An' if sometimes our conduck isn't all your fancy paints:
Why, single men in barricks don't grow into plaster saints;

I smell alot of...

[IF] ,

If you can keep your head when all about you
Are losing theirs and blaming it on you,
If you can trust yourself when all men doubt you
But make allowance for their doubting too,
If you can wait and not be tired by waiting,
Or being lied about, don't deal in lies,
Or being hated, don't give way to hating,
And yet don't look too good, nor talk too wise:
If you can dream--and not make dreams your master,
If you can think--and not make thoughts your aim;
If you can meet with Triumph and Disaster
And treat those two impostors just the same;
If you can bear to hear the truth you've spoken
Twisted by knaves to make a trap for fools,
Or watch the things you gave your life to, broken,
And stoop and build 'em up with worn-out tools:

If you can make one heap of all your winnings
And risk it all on one turn of pitch-and-toss,
And lose, and start again at your beginnings
And never breathe a word about your loss;
If you can force your heart and nerve and sinew
To serve your turn long after they are gone,
And so hold on when there is nothing in you
Except the Will which says to them: "Hold on!"

If you can talk with crowds and keep your virtue,
Or walk with kings--nor lose the common touch,
If neither foes nor loving friends can hurt you;
If all men count with you, but none too much,
If you can fill the unforgiving minute
With sixty seconds' worth of distance run,
Yours is the Earth and everything that's in it,
And--which is more--you'll be a Man, my son!

A Kipling fan as well? Good on you boy!

Personally, I really like the on in my sig, the Grave of the Hundred Head
Quote:

There's a widow in sleepy Chester
Who weeps for her only son;
There's a grave on the Pabeng River,
A grave that the Burmans shun;
And there's Subadar Prag Tewarri
Who tells how the work was done.


A Snider squibbed in the jungle,
Somebody laughed and fled,
And the men of the First Shikaris
Picked up their Subaltern dead,
With a big blue mark in his forehead
And the back blown out of his head.

Subadar Prag Tewarri,
Jemadar Hira Lal,
Took command of the party,
Twenty rifles in all,
Marched them down to the river
As the day was beginning to fall.

They buried the boy by the river,
A blanket over his face -
They wept for their dead Lieutenant,
The men of an alien race -
They made a samadh in his honor,
A mark for his resting-place.

For they swore by the Holy Water,
They swore by the salt they ate,
That the soul of Lieutenant Eshmitt Sahib
Should go to his God in state,
With fifty file of Burmans
To open him Heaven's gate.

The men of the First Shikaris
Marched till the break of day,
Till they came to the rebel village,
The village of Pabengmay -
A jingal covered the clearing,
Calthrops hampered the way.

Subadar Prag Tewarri,
Bidding them load with ball,
Halted a dozen rifles
Under the village wall;
Sent out a flanking-party
With Jemadar Hira Lal.

The men of the First Shikaris
Shouted and smote and slew,
Turning the grinning jingal
On to the howling crew.
The Jemadar's flanking-party
Butchered the folk who flew.

Long was the morn of slaughter,
Long was the list of slain,
Five score heads were taken,
Five score heads and twain;
And the men of the First Shikaris
Went back to their grave again,

Each man bearing a basket
Red as his palms that day,
Red as the blazing village -
The village of Pabengmay,
And the "drip-drip-drip" from the baskets
Reddened the grass by the way.

They made a pile of their trophies
High as a tall man's chin,
Head upon head distorted,
Set in a sightless grin,
Anger and pain and terror
Stamped on the smoke-scorched skin.

Subadar Prag Tewarri
Put the head of the Boh
On the top of the mound of triumph,
The head of his son below -
With the sword and the peacock-banner
That the world might behold and know.

Thus the samadh was perfect,
Thus was the lesson plain
Of the wrath of the First Shikaris -
The price of a white man slain;
And the men of the First Shikaris
Went back into camp again.

Then a silence came to the river,
A hush fell over the shore,
And Bohs that were brave departed,
And Sniders squibbed no more;
For the Burmans said
That a white man's head
Must be paid for with heads five-score.

There's a widow in sleepy Chester
Who weeps for her only son;
There's a grave on the Pabeng River,
A grave that the Burmans shun;
And there's Subadar Prag Tewarri
Who tells how the work was done.

That's just it. Chris can't quantify the variables. But then neither can you. So there is insufficient information to arrive at any conclusion, mathematically speaking.


Okay, based on what I've learned so far (yes, I have things to learn; try not to faint...), I can say that the initial acceleration was too great for a weight of about two pounds (A guess at the weight of a puppy of that size), and what seems to be a lack of acceleration as wind resistance is encountered on the way down, again indicating (to ME) that it's weight is not truly that of a real puppy.
Plus it swung real fast (very much like a weightless doll) as the Marine's arm switched from backwards to forward motion for the launch.

But like CTS noted, hard numbers are impossible here.

Maybe I should have just skipped the details of my brainworking and said "Awww, bulls**t, that looked like a freakin' doll to me" and that might have avoided this whole thing, but ya have to admit, this thread was NOT boring...
Even Geezer came up with the funny!

Momentum: All things being equal, a heavier puppy has more momentum, and can travel faster than a lighter puppy. But all things are not equal, including initial force applied and initial velocity achieved--which was Chris' argument. So you have no idea what velocity was and what the momentum would have been.

Laws of motion: Neither inertia nor reciprocity of action is relevant. (Yes, we know the puppy will keep moving until something slows it down. And yes, we know something will slow it down. But tells us nothing about the weight of the puppy without knowing initial velocity.) That leaves acceleration, which we can address next.

Acceleration: I only watched the video once, so I could be wrong here. But it seemed to me the trajectory of the puppy was in a largely horizontal arc, with almost no straight vertical drop at the end. As soon as the puppy left the hand of the soldier, there was no longer any force being applied. The puppy would have simply lost velocity, not gained. I would disagree with Chris there was acceleration to begin with, except for the very small vertical drop at the end.

Centripetal force: The radius was the length of the soldiers arm. The puppy was hurled many times more that length. For most of the puppy's path, the difference made by mass in centripetal force would be insignificant. Again, what matters is the initifal velocity, which we do not know. So centripetal force, as I see it, is neither here nor there.

None of these terms are relevant in either supporting or refuting Chris' position. Ultimately, in my view, the video does not provide enough mathematical information to guess the weight of the puppy. It is not something that can be either asserted or refuted as a matter of fact or definition.


...and let's ALL give it up for Canttakesky who clearly knows more about physics than the rest of us could ever imagine.

Incapable of resisting the physics discussion... I'm about to be a know-it-all. If you're one of those who doesn't like that, skip on by this post.

So, there are three forces in effect here:

1. The push from the soldier's arm. I only watched the film once and it didn't strike me as odd that the man launched the puppylike object so fast, but then the launching happened behind his body and I couldn't see it well. Still, light puppy, strong arm. I wouldn't be surprised that a grown, physically fit man could launch ~2 pounds so easily.

Chris, the fact that the man held the puppylike object by the scruff means he held it to one side of its center of mass. This doesn't make it impossible to throw, it just gives it spin when he releases it, as a pool ball has spin if the cue hits it off center.

2. Gravity. No matter the weight of the puppylike object, the gravitional acceleration is the same. It pulls down. This doesn't tell us much.

3. Air resistance: this is where the weight (inertia) of the puppylike object becomes an issue. [Edit for messed up wording:] The force of air resistance is only strong on a low density object. (High surface area to act on, not much mass to push against.) This is why a feather falls slower than a penny. A light stuffed puppy would have been slowed more by air resistance than a heavy real puppy. Sadly, I don't recall seeing the plo slow down as much as I'd expect of a low density object. I wasn't watching for that, so I'm not sure.

Back to the spin though. Air resistance also slows the rotation of a spinning object,and a low density object has less inertia and will be slowed more. Spin a styrofoam peanut. Spin the same shape/size rock. Styrofoam slows down quickly while the rock keeps spinning, right?

It seemed it me that a spinning stuffed animal that weighs very little should not keep spinning so quickly. That plo was spinning very quickly. This suggests enough rotational inertia, enough mass in the object, to overcome air drag.

Which makes me cringe, so I'm not going to think about it anymore. :(

Yeah, the spin was definitely there.

Just watched it three more times, it sure didn't fall as fast as I'd expect it to, plus a bit more of a bounce than the 'splat' I'd also expect.

Okay, but two things: I feel that it weighed maybe 1/3 to 1/2 of a real puppy's weight, which would account for the rotational inertia, HOWEVER, I've seen cats in mid air extending their legs and ( please excuse my lack of technical language here) 'disrupting the single-axis spin'. The plo spun on a clear single axis, and moved no appendage even once. Once again, I'm left with the phony-puppy assumption.

Just a correction on the aerodynamic(Drag) side of the equation. The total drag on the puppy is the sum of the pressure drag and the skin friction drag. Neither of these is dependent on the mass or density of the puppy. For pressure drag what matters is the cross sectional area of the puppy, for friction drag it's the total surface area. Because the surface area and cross sectional area would be approximately the same for a stuffed animal or a real puppy, the drag coefficient can be assumed to be the same for both. This leaves velocity as the only important factor in determining drag. Keep in mind that drag is related to the square of the velocity.

Another issue is the flight path of the puppy. This is primarily determined by the vertical component of velocity imparted to the puppy when it is released and doesn't tell us much. The only significant factor here is the horizontal distance, since all projectiles essentially fly in a parabolic curve.

The velocity of the puppy when it leaves the soldiers hand as previously mentioned is governed by the basic equation F=m*a(force equals mass x acceleration). Acceleration is defined as the change in velocity with respect to time as given by the equation a=dv/dt where dv in the change in velocity and dt is the time interval that the force F in applied. Combining these equations we can get the form F/m=dv/dt or dv=(F/m)dt. From this we see that the velocity of the puppy is determined by the force F of the soldiers hand, the mass of the puppy, and the amount of time the force is applied.

The problem we have here is the one Cantakesky eluded to earlier. Without knowing the mass of the puppy/fake puppy, and the force, and time applied, we can't really determine anything helpful using the laws of physics.

Just from personal experience my best guess is that it was a real puppy or a stuffed animal weighted to make it fly better. Can't completely rule out the stunt cat in puppy suit either.

But isn't the drag's effect changed by the weight of the object? I mean, doesn't a heavier object need a greater surface area to be affected by drag similarly to a lighter object?

First thing is that you need to do is separate the concept of weight from that of mass. Mass is independent of Earths gravitational field and is what is most often used in physics. Weight comes from the fact that all mass on Earth is effected by the earths gravity. If you drop an acorn or a feather in a vacuum on the earths surface both will accelerate towards the center of the Earth at 9.81 m/s2. Just like Galileo dropping two steel balls of different mass from the Leaning Tower of Pisa, both hit the ground at the same time. It's a good thing he used balls with enough mass and similar surface areas, making the aerodynamic drag on them an insignificant factor or he would have gotten a different result.

Drag is completely independent of weight or mass. The only other factors that effect drag in subsonic air flow are the density and viscosity of the air, but in this case that too would be the same for both puppies.

I think your mention of surface area is related to your understanding of the aerodynamics of aircraft creating lift with an airfoil. In this case the idea is to maximize lift by having as much surface area as is required to lift the aircraft but at the same time minimize the parasite drag that is a result of the creating lift.

Guys, this is apparently something the guy said...not sure about the source so take it with a grain of salt

The Marine's name is apparently David Motari
He is on myspace if you feel so inclined to ask him yourself

“I want to say first of all that I am really sorry for the whole puppy thing. I don’t know why people are so pissed. It was a FUCKING STRAY!!! Get the fuck over it! You know how many people I see get blown away on a regular basis?!?! Shit Man Not only the towle heads out here but my own friends!” ~ David Motari ‘the Puppy Killer’ just updated his MySpace page: “I want to clear somethings up before tomarrow. This might be hard to believe but I am sorry about the dog. At the time I just really didn’t care. When you are constantly under fire sometimes people develope a different sence of humor than what others are used to. That video was from over a year ago and i dont know who put it out there but it wasn’t me. It has been a real hard day. I don’t know how they got my information but someone got all my information and i had to disconnect my parents and my girlfriends phone. not to mention i had to redo my myspace because it got hacked. I just want this to end.” And: “What, you expect me to carry a stray sick dog from patrol 10+ miles back to camp with me. Did you know that we’re not supposed to have dogs? Did you know that there isn’t medicine available for animals out there? So what the fuck do you want me to do with it. It was going to die a slow and horrible death. Sorry you guys saw that, but it wasn’t supposed to ever been shown. Usually what happens is we shoot them. I was being “creative” that day and decided to throw the dog instead. If i could take it back, I would. Either way, I did the dog a favor. Sorry if you can’t understand that.” AND: “Look, you guys didn’t know that the dog was sick and starving by the road. I was helping it. That dog was going to die anyways”

Because the surface area and cross sectional area would be approximately the same for a stuffed animal or a real puppy, the drag coefficient can be assumed to be the same for both.

This is progress !

I think amidst all the preliminaries I may have intimated to you that this could end up being a long conversation...

That perhaps it was 'answers' that you were seeking...

I was asked once by a beautiful lady friend if I'd take her for a flight in a sailplane...Which I , feeling the compulsion for magnanimity ,, was able to oblige , and which she was able to enjoy...She didn't have to understand flight physics , she just had to recline in a semi-supine position and enjoy the ride . No prob .

But , on another occasion , as co-workers in a very techie job , our conversation turned to a particular area of science , where she had some prior notions prepared in regard to that field...

She challenged my notions intensively and found most of them contrary to her own , because I was able to give certain logically-supported reasons for my beliefs . She found that the conversation was frustrating , and exclaimed ,

" You seem to have ALL the answers , and I hate that about you ! " It stopped her in her tracks when she heard me say,
" You know , hate is a strong word...No , I do not have all the answers...Never told you that I have all the answers , and I'd never try to make you think otherwise...What you are finding to 'hate' about me is that I'm learning to ask better questions ."

Her mouth fell open a bit , 'cause she'd become 'speechless' , but as long as I knew her after that , she was really kind of switched on , with a whole new attitude...

'Attitude' , as it happens , is an important word in relation to many flying objects , especially those inhabited by intelligent crews...

That's why folk shouldn't be ashamed of their 'learning', and that's why I think learning is much to be preferred over 'education'...

A persistent perception that folk have about education is that it's something that they can go and get , like a service that can be received in a manner similar to getting a haircut..Just show up , and 'voila'!. Not so much .

Learning is much more of an attitudinal process...
It's a way in which a person finds out just how much they ALREADY 'know' , a foundational site-preparation for a questing mind , if you will...

That's how I can tell you've 'grown'...You have a different outlook , and you're asking continually-better questions...
