Superstring theory requires a lot of extra dimensions,
and the
crews of various spaceships tend to zip around through
the
fourth dimension from time to time.
It occurs to me that, just as a 3D extruder can extrude
things
(like aluminium sections) which have useful 2D profiles,
a 4D
extruder
could extrude, say, teapots or complete car
bodies.
These extrusions could then be sliced up into individual
3D objects.
MaxCo. is considering patenting this idea, in anticipation
of
the fourth dimension.

I thought 3 Dish was a square meal. |
|
| |
Would it not just always extrude clocks? - time being the 4th dimension. |
|
| |
Well, if you're going to be picky... I was confining
myself to the traditional space dimensions. |
|
| |
Clocks have nothing to do with Time; in fact, they make a
mockery of it. |
|
| |
<at this point, [The Alterother] manifests just enough self-
restraint to keep from launching into another of his wierd
half-formed intuitive theories concerning the nature of
reality> |
|
| |
Mismatch between title & idea. 3D extruders well baked. |
|
| |
Also, teapots are not made from metal. Not ever. |
|
| |
//Also, teapots are not made from metal. Not ever.// |
|
| |
Taking that statement at face value - what else do we know besides metal which is extruded? |
|
| |
Are the teapots made of pasta? |
|
| |
PVC and other plastics, certain ceramic compounds, pet
food and other kibble, fiber-pulp products both synthetic
and natural... |
|
| |
//Also, teapots are not made from metal. Not
ever.// Ah yes, you're right. I was thinking of
stainless steel, silver and all those other famous
non-metals. |
|
| |
But imagine the sheer aesthetic joy of seeing a
smooth continuous 4D ribbon of teapots emerging
from the strangely twisted nozzle! Imagine the
sheer profits attainable by just slicing this ribbon
up into individual, perfectly-formed teapots!
Moreover, the same extruder could make teapots
of any size, simply by adjusting the intervals at
which the 4th-dimension blade sliced the
extrusion. |
|
| |
// a smooth continuous 4D ribbon of teapots // |
|
| |
<frantically flicks through contract looking for Sanity Clause> |
|
| |
+1 for blowing my mind. Physicists might say those
extra dimensions are "too small" to use, but I'm sure
there's a solution involving doughnut-shaped black
holes. |
|
| |
//a smooth continuous 4D ribbon of teapots// |
|
| |
Actually, that should have read "a smooth
continuous 4D ribbon of teapot" |
|
| |
alternatively of course is to get a tiny teapot and use 4D water. |
|
| |
That's fine until you spill boiling water all inside
yourself. |
|
| |
//sliced// Why? Wouldn't this work just as well if it
were left intact? |
|
| |
Because you'd have one teapot hugely extended in
the 4th dimension, which would be unweildly. It
would also take a lot of tea to fill it. |
|
| |
The aim is to create a continuous extrusion, much as
aluminium profile is extruded and chopped into
convenient lengths far more cheaply than casting or
forging individual pieces. |
|
| |
//It would also take a lot of tea to fill it.// If that's
true, then your chopped teapots will leak tea into
the fourth dimension. |
|
| |
//unwieldy// You just have to crumple 3-D
spacetime so that all the places requiring teapots
are adjacent to each other. Then it's not unwieldy
at all. |
|
| |
I believe the solution we're looking for would be a klein
teapot. |
|
| |
Certainly not. It would leak badly, since its inside is
the same as its outside. Also, you couldn't fill it,
since it would have zero volume. |
|
| |
But it would simultaneously have infinite volume, presuming that the rest of the Universe were completely filled with tea leaves and boiling water ... |
|
| |
Thank you, enemy mine, I was trying to figure out how to
explain that elegantly. Also, the tea would would always
come out hot and fresh, because it would essentially be
the same tea you originally put in, no matter how 'long' it's
in there and how 'much' you pour out. |
|
| |
What I mean to say is that, if you fill the klein teapot with
its presumed volume of hot water and tea leaves, the
universe as presumed to contain and be contained within
_will_ be filled with hot water and tea leaves. Forever. |
|
| |
That's going to give Stephen Hawking something to think about. |
|
| |
Doesn't every 3D object already come with it's reality assigned 4th dimension component? |
|
| |
Is a quantum-entangled shotglass both half-full and half-empty at the same time ? |
|
| |
The whole raison d'etre of shotglasses is that they are either full or empty. The transition between the two states should occur in the Planck time and be represented by the Heaviside step function. |
|
| |
//reality assigned 4th dimension component// |
|
| |
<PeterCook>Yes. The interesting fact about the fourth dimension is that the people in charge assign it.</PC> |
|
| |
Extrude 4-D material through a 3-D hole for a 4-D
ribbon that can be sliced into teapots. |
|
| |
What does 4 dimensional ceramic look like anyway? |
|
| |
That depends very much on the shape of the 3D
hole. |
|
| |
Well ... try to visualise a spherical tesseract made of fused silica, rotated by 90 degrees in each of 4 orthogonal adjacent Riemann planes. |
|
| |
Got that ? Good. It's nothing like that at all. |
|
| |
I'm reminded of Sir Terry's 'The Lost Continent', specifically
the 4-dimensional cave drawings that show animals not
just as they are but also as they always have been and will
be. |
|
| |
//try to visualise a spherical tesseract// |
|
| |
The closest you could get to visualizing a 4D
teapot extruder would be to envisage a solid
metal die containing a teapot-shaped cavity
(complete with the core, of course). |
|
| |
The feed (and the exit of the extruded teapots)
happens along the 4th axis of the system. The
easiest way to visualize it is to imagine an infinite
number of egg-timers, with their waists
populating the entire space in the mould. |
|
| |
It might make commercial sense to ship the
complete extrusion to its country of destination,
rather than dicing it into individual teapots at the
point of extrusion, since
many bulk carriers charge by cubic capacity rather
than weight (let along quartic capacity). |
|
| |
Further shipping economies could be made by
producing two extrusions - one inward and one
outward. These two extrusions would nest nicely,
allowing twice the amount of teapot to be
packaged in a given cubic volume. |
|
| |
//the exit of the extruded teapots) happens along the 4th axis of the system// The problem with this is that the completed items end up somewhere off along the 4th dimension rather than here, which is not so convenient. It's like me saying, I'll give you a tiger if you like? And you say, why, yes I would like, and I reply, here it is, oh actually it's in Africa. |
|
| |
A piffling problem. Teapots are fairly simple to
move. In practice, rather than laying the extrusion
down and dicing it (which would leave the teapots
distributed over a distance), it would be easier to
move the extrusion past a fixed dicing blade, so that
they are all in the same place afterwards. |
|
| |
I'm still obsessing over the idea of 4D tea that runs through several parallel universes: make a small pot that serves many, and whichever universe uses the last bit has to make a new batch. |
|
| |
I remember this from the pants thing. (update: [mb] suggested dimensionally novel pants at idea: Trousers based upon the recirculating washroom towel principle) actually
this could be the biggest thing since atheism. |
|
| |
I have the impression that the form of the world I
perceive is rather like the continuously group
modified (world being) at the Zelazny amber sci fi
writings. If you can create an actual human
producible object that varies continually,
controllably across a different dimension, then it
supports this other nonreligious view of creating a
fossil record along with actual animals
simultaneously as a result of just rotating a kind
of graph of beingness. [MB] here could create not
just continuous pants, yet create preexisting
historical pants at their energy minima local
contexts, like fossils. The really nifty thing would
be days of future pants at present. |
|
| |
so Im thinking about how to actually make it
function, i think. Anyway I think I once figured
out how to fake the fossil record with something
similarish. that is like, if god made everything,
what dimensionality would be used to create a
fossil record contemporaneous with actual
existing creatures. Changing the angle of that
creature constructor would vary the fossil record
simultaneous to the newly different living
creatures. |
|
| |
//Days of future pants// That is a title in search of
a novel, if ever there was one. |
|
| |
[beanangel]: if you can find a copy, read 'Strata' by Terry
Pratchett. It's a very early work. |
|
| |
[mb] this differs from superstring theory technology yet could create 4d adustable pants |
|
| |
one approach to chronoextruded materials is to immanentize quantum glider guns at a fog. |
|
| |
Rather the way particles condense material at a cloud chamber as they zing their way, the creation of quantum linked photons or even atom groups could act like automata glider guns suddenly coalescing matter at multiple quantum linked places simultaneously to create multiple copies of an item from a data file |
|
| |
So compare a sooper toobular bubble having a shape from a wand, unformed matter fog would drift through an area continually producing multiple materialized quantum imaged thingies, along with the simultaneity you also have the normal chronological path length of the automata glider gun as well as the specific automata rules that describe how much spread n move the immanetized quantum glider guns actually do. |
|
| |
If you did make a photoncaster like that it would actually make, like 3d pants, across a duration Where Changing One Of The Pants Would Change All Of The Pants regardless of their actual moment of instantiation its just that they are fog pants until you spray fixative on them. |
|
| |
also [mb] kind of like you say, you could (nonlinked photon) weave or unweave the nonlinked parts (area) of each quantum linked glider guns actual local area to create "interior" variation that might otherwise be "impossible" |
|
| |
The square of the distance lightspread rule as well as the instantiation of glider guns also supports the the same extruder could make things of any size simply by adjusting the intervals at which the 4th-dimension "unlink" function said each item was complete |
|
| |
so you have chronological creation latitude with immanentization as well as customization |
|
| |
I see words but no meaning... but thank you
nevertheless. |
|
| |
//I see words but no meaning// - I was sitting here thinking, "This sounds like a description of the world where [beanangel] lives." Then, he saunters in and states //I remember this from the pants thing.// Well, I guess... If you see a person out wandering around who appears to have no pants, you can now just assume that the person really does, or will, have pants, right after they are immanentized, so it's no big deal, pay it no mind, g'day, fine weather we're having, isn't it?; oh, yes, top-notch, 'cept for the Thames crawled up the side of my flat again last night; Ooh, blimey, sorry mate, that's not a good biscuit - say, you have any idea how I get this brick out of my head?; Oh, that's a nice one, adobe, makes grit on your teeth, yep, all you have to do is just lean away from when it came and it'll missed you. Cheerio, haven't they? |
|
| |
//I remember this from the pants thing.// |
|
| |
I know I'm stepping out on a limb, but [marked-for-
tagline]. |
|
| |
<stealthily applies saw to limb onto which [TheAlterother] has just stepped> |
|
| |
[b] You're talking about the collapse of an object existing in a large width of timeline, all into a smaller width. |
|
| |
So if the entire large width started off wearing, say, designer jeans from the 80's, at the end of the operation, the person-sheaf to either side of the middle would find themselves pantsless, and the thin middle-sheaf would be enrobed in a sturdy set of original Levis which would probably be on fire too, but you can't have everything. |
|
| |
Hence the term, "The Trousers Of Time" ... |
|
| |
A concept grounded in Norse mythology... interesting. |
|
| |
I think that if we're going to carry on using
"immanentize", we need at least a lemma to show
it's a real word. |
|
| |
actually I recently read at softpedia that 114 AMU molecules are observable as waves with a double slit procedure. Now think of [mb]s idea with a huge plurality of unobserved 114 AMU polyethylene double slit waves overlapping each other. observe them from just the right angle you get overlapping mer fields to create a polymer thousands of AMU big, with durable physicality, do this enough, you've got immanentized pants |
|
| |
Uh-oh. I was suggesting "don't look". So you're saying we have to look, or the pants won't show up? |
