Earth's Core Has Another Layer, Scientists Claim

Hmmm ~ "pretend to know" ~ all of this comes to me in dreams. I draw on the Overmind ~ don't you?

(I also read books and study, and the whole idea seems to have something to do with gravity and melting temperatures )

What has science done for us in the last 100 years?

"But apart from the sanitation, the medicine, education, wine, public order, irrigation, roads, the fresh-water system, and public health, what have the Romans ever done for us?"

"Actually it is because airplane wings deflect particles of the air in a downward motion. For every action there is an equal and opposite reaction."

Well, that blows my theory of the wings creating a low pressure bubble that creates lift...

Gee. Wow. You read books and study.

Have you ever been asked by any scholars to write papers about this stuff? I have, and it's not my field.

I used to believe that too. But winged-flight comes from air displacement, not because of the Bernoulli effect on a shaped wing. This is e.g. why planes can fly upside down.

That was answered about a hundred years ago: from decay of radio active elements in the earth’s core. There’s very little of them, but the core is exceptionally well insulated.

The outer gore where temperatures reach 10 gazillion degrees.

Actually it is because airplane wings deflect particles of the air in a downward motion.

Some of the lift comes from the air having to run a farther distance over the top of the wing, than the bottom. This creates a low pressure area above the wing, while a higher pressure area is below the wing.

At least in theory, and according to MOST wing design.

I have flown Piper Cherokee's and the wing is symmetrical. So... it's kind of like the Bee can't fly theory.

Hmm ~ and your credentials for wiseacre are....., and .......!

My word ~ a veritable Genius.

We are blinded by your shining brilliance, and say hi to your mom for me ~ tell her NO MORE NOONERS ~

Well, ...that'll just have to be your little secret. And to think you were bad mouthing others about the missle.

[jaydubya2]

I suppose it depends on the type of wing it is (asymetrical or other) and the angle of attack.

[muawiyah]

Weren't most of the early design formulas still useful irrespective of the force models imagined in the mind?

Like, they could build successful airplanes ignorant of how they actually worked ~ right?

[ml/nj]

Hmm ~ and your credentials for wiseacre are....., and .......!

I have science degrees.

Actually, it comes from a combination of both.

The 'kite effect' and the Bernoulli effect BOTH provide lift.

Airliners have Flaps on the rear and Slats on the front. The flaps generate most of their lift from air displacement, and the Slats provide most of their lift by changing and adding to the curve of the wing to increase the Bernoulli effect.

[muawiyah]

Amazing ~ and I suppose you think a degree of some sort in mere science qualifies you to talk back to someone with substantial studies in statistical analysis techniques, systems analysis, Calculus, etc ad infinitum ~ who ALSO has degrees that required knowledge of a foreign language (most of those “science degrees” don’t).

[SeeSac]

Well, that blows my theory of the wings creating a low pressure bubble that creates lift...

Somewhat. But remember, vacuums do not suck. In order for a force to be created on the wing by the gas molecules, a change in the momentum of the gas molecules is required. The wing creates a pressure difference and that 'pressure difference' model is still taught.

I thought the earth was flat?

Remember that wild idea for sending a probe to the center of the earth? Basically, you would pour a large quantity of molten iron into a crack in the earth. The theory is, the extreme mass of the molten iron would cause the crack to propagate downward, and the iron blob would descend to the center of the earth over a period of several days. Embedded in the iron would be a probe that would send information back to the surface acoustically.

And "worked" for the Post Office! Give me a break!

Ooooo. Calculus. People like me took that in high school. And BTW, for my BS I was required to take four useless semesters of German.

Hmm, and you imagine America's second largest employer doesn't have room for mathematicians, statisticians, economists, engineers, and so on?

What you don't know is that every large organization has a class of people who do the heavy duty thinking and design the systems and processes that make the organization far more efficient than local centers of activity could make it.

That way only a few need to have the higher degrees ~ others, like you, who imagined that 4 semesters of German was wasted get to deliver the mail. Plenty of guys on the street have degrees comparable to yours.
