Principle of volume |
I've been working on a "new" principle of geology. I call it the
principle of volume, and it is applicable to physics as well. When you
look at the earth, you can see how the largest volume of the earth is
on top, and the smallest volume of the earth is in the core. This is
the principle of volume.
Rocks of greater size rise to the top above rocks of lesser size.
I've done an expiriment to test this theory. I bought 3 boxes of these
toy building blocks that are very much like legos. They all have the
same density and are the same size. They can connect on every side,
and on the top and the bottom.
I filled a kitchen bowl with the blocks, and connected 12 of the blocks
to form a solid 3x3x3 block. I left the lest of the blocks loose. I
then shook the bowl up for about 5 minuets, with a lid on. I turned it
upside down and shook it, sideways, etc. I then put the bowl flat
down, and gently shook it from side to side.
When I opened the lid the big block was on top!!!
This is a universal principle, and can create boyancy. Density is not
the only thing to consider when talking about boyancy, size is
important too.
If you have a balloon filled with hot air it will rise if the volume of
hot air exceeds the weight of the balloon. What is interesting about
this is that the ratio of volume to surface area of a sphere isn't 1:1.
As the surface area of a sphere increase the volume increases
exponentially. Because of this, if you have a very large balloon, it
will rise into the air with less heat, because it has more volume to
surface area.
With a large enough balloon you don't need hot air at all, and the wind
and air pressure will simply carry it up into the air because of the
principle of volume.
What do you think!?!?!?!

Agreed.

No thats rubbish. You will allways need a temperature difference between the
inside and outside.

Nope. Buoyancy is a different phenomenon than the differential settling
you're talking about. Note that buoyancy is something that occurs in
*fluids*. You need to understand the difference between a fluid and a
bucket of gravel.

I think you should study 8th grade physics before attempting to solve the
mysteries of the universe. They are only mysteries to the ignorant.
If you had studied 8th grade physics you would be aware of size segregation,
assuming the particles have the same density. Now if the large particle has
a density 10 times greater than the small particles, which one will be on
top?
You will find the answer in the Liberal's Favorite Movie "Brokeback
Mountain". The dense one is on the bottom.
Happy trails,

Wonderful choice of example - I'll pass that quote on to Neil & John

No, ..he's quite right. This is why Plate Tectonics has convection -
or rather, doesn't have convection. The bigger the planet, the more it
doesn't have convection:-

A quick scan of your reponses, none mention the Brazil Nut Effect.
Whenever a can of mixed nuts is opened, the brazil nuts tend to be on
the top. This phenomenon seems counterintuitive, because the brazil
nuts are more massive than the peanuts, cashews and other nuts in the
can. How can this be?
The effect can be extended and used to study problems in construction,
consumer packaging, and geology.
http://jfi.uchicago.edu/~jaeger/granular2/Brazilnut.html provides a
middle level introduction to current work.

2004 2 July A5
MATERIALS SCIENCE: ON GRANULAR SEGREGATION
The following points are made by Troy Shinbrot (Nature 2004 429:352):
1) Every farmer can attest to the curious fact that the largest crop
each spring is the boulders that appear, untended, on open fields.
Common wisdom holds that this crop is loosened from the soil by frost
heave, and rises because small pebbles can slip beneath large
boulders, but not vice versa(1). This is the "brazil nut effect" --
named for the fact that in a container of mixed nuts the brazil nuts
always seem to rise to the top. Because similar processes and effects
occur in pharmaceutical, chemical and food processing, the problem of
granular segregation has earned serious attention(2,3).
2) The first complication to the simple picture of pebbles slipping
beneath boulders (termed "percolation") ... (snipped)
3) Over the past decade, however, our understanding of the segregation
of large particles in vibrated beds has been challenged by experiments
revealing ... (snipped)
4) In fact the RBN effect turned out to be even more complex than
realized at first. (snipped)

No, buoyancy is different. Yes, both buoyancy and the brazil nut effect
can cause things to rise to the top, but that doesn't mean that they're
the same.

Cool, thanks! For a minuet I thought I was a genius. Maybe I could
discover why the brazil nut effect operates, because it still seems to
be somewhat of a mistry.

Do you think the brazil nut effect could make a large enough balloon
fly, or solve any mistrys of the universe?

The container shakes,
the side of the container slow this shaking
the inner small parts shake to the top of the outer
parts because they can move more freely,
the parts on the sidewall get pushed down
as all of them push down they end up pushing more
up in the middle.
and the bigger items can not fit into the "smaller stream"
of parts moving down on the sides.
:)

No on the balloon.
sorry
but...
The universe.. is still not completely known of course
so the brasil nut effect may prove to solve something
to do with the universe but... there is no proof it will
or won't.

Small things can fall into big holes.
Big things can't fall into small holes.
Small things have more opportunity to move downward.

This principle is used in number of aids to help survive avalanches.
One can wear and inflate a balloon device that keeps higher in
the snow.
However density is more applicable to geology.
As salt and shales are buried in sediments, they'll
start flowing upwards once the surrounding rock
is compressed denser. Trillions of dollars of oil are
associated with these structures, so they are being
thoroughly studied.
