I've often thought that what we consider beautiful curves are those that
have simple mathematical equations. It would be interesting to try to
test this.

Isn't it interesting that potters achieved these with only they
eye. The high point of form in Sung China was mostly related to
beautiful curves.
The thing I noticed what was different in my teacher's work
compared to his teahcer's, Hamada, was that while Hamada depended on
gesture, like Choson Korean work, my teacher depended more on graceful
curves, like found in Sung work.

Dear Janet Price,
It is claimed by some that Euler's Formula is the most beautiful formula in
all of Mathematics. The description I have states, (Quote), " Thus, the
transcendental number e raised to the power of the product of the imaginary
unit and Pi, also a transcendental number, yields exactly minus 1. "
(from Jan Gullberg, "Mathematics. From the Birth of Numbers". ISBN
0-93-04002-X ).
I wonder if an expression that is based in the imaginary and the
transcendental can be made concrete ?
This may be a proposition you and others may wish to test.
Best regards,
Ivor Lewis,

OK Ivor, now you've gone and done it. ;-) Forty years ago when I was
studying mathematics at the university (before I gave it up as a way to
spite my mother in my youthful rebellion) I might have understood exactly=
=3D
what you are talking about. The same as with chemistry, which I still
understand totally and completely, as long as the textbook is open in fro=
=3D
nt
of me. The moment I close the text, it is rendered just as totally and
completely into gibberish.=3D20
It used to be axiomatic that it (whatever "it" may be) was undeniably tru=
=3D
e
if you saw it on television. Now one needs only the internet to discover
absolute truth. Especially WikiPedia. And so that is where I sought an
explanation of Euler's Formula. And magically, it was there, complete wit=
=3D
h
graphs.=3D20
http://en.wikipedia.org/wiki/Euler's_formula
Midway down that page is a 3-D visualization of the formula. I would gues=
=3D
s
that the grey curves are derived from the sine and cosine functions drawn=
=3D
along the X-Z and Y-Z axes, while the red line is a combination of them i=
=3D

all three axes. But just look at the red line. Imagine a pot with a surfa=
=3D
ce
that matches that red line through one revolution (the Wiki picture shows=
=3D
2
revolutions of the curve).=3D20
Is there a math wiz in the house who could project that red line onto a
plane that includes the z-axis and give us the coordinates of a dozen or =
=3D
so
points along the side of that hypothetical pot? Then we can sketch in the=
=3D
rest of the curve by eye, cut out a cardboard (or other sheet-good)
template, and throw an actual pot that reflects Euler's curve.=3D20
And then we put that idea up there with the Greek ideal of the golden mea=

cheers and happy New Year to all,

Steve...
Every time I think I have an original idea, I find that it is not so
original after all. I had the same spirograph idea a few years ago, but
decided it was too much work just to make a couple of platters. I had
planned to use gilmer belts, which are toothed automotive drive belts,
mounting them inside stiffening rings as the outer race, then fashioning
some slightly domed gilmer pulleys to hold the sgraffito stylus and to run
the laps inside of the gilmer belt ring. The slight doming of the pulley
was to prevent the pulley edges from gouging the leatherhard clay, and also
to allow the tall pulley to slide down into a dished clay surface while
still remaining straight up and down and sufficiently engaged with the teet=
h
of the gilmer belt, which also remains straight up and down. A second idea
was to employ a similar system to run a cordless Dremel tool with a carbide
burr around a soft bisque piece, thus eliminating the possibility of
gouging.
Great minds think alike, and so do we! Perhaps my gilmer belt idea will
give you even better ideas. If you use it, I should get a free Steve Clay
Spirograph Tool, autographed!
Take care.

Perhaps a Foucault pendulum. Instead of dispensing glaze, it dispenses
thick slip into a suitably curved plaster form, thus building up the entire
vessel spirograph-style! Set it up in different cities to make vessels
completely unique to the corresponding latitude! Sounds like "art" to me.
Don't any of you steal our idea!
All the best.

What a fascinating and beautiful site, Kathy. Thank you for sharing it.
The mind reels with ideas impossible to realize but wonderful to consider.
You will now be responsible for the hours I will waste exploring this littl=
e
detour!
I often think about how I might incorporate fractals and other mathematical
oddities into my work, prodded by an admonition in one of Richard Feynman's
books. The closest I have ever come was the rather shallow appropriation o=
f
a portion of the Julia Set as a decorative motif (
http://www.flickr.com/photos/jamesfreemanstudio/2744113780/).
Can "art" be the product of the left hemisphere of an ordered mind?
All the best.

Very cool.=3D20
My favorite takeaway from fractals is an indirect quote from Beno=3DEEt =3D

Kathy...
I shall ask him, next time I see him! I am meeting he and Jim Morrison at
Elvis' doughnut shop in Kalamazoo next week.
In seriousness, though, I have never considered architecture to be "art".
Artistic, to be sure, at least at rare moments (Greene & Greene, anyone?),
but not art (and not speaking about folks like Gaudi, who were artists whos=
e
medium was buildings, rather than architects per se). I think the only
reason that art historians grudgingly include architecture and pottery in
their texts is because they are the closest things to art which have
survived the ravages of time! I say this having studied architecture (alon=
g
with commercial art) in high school, as one of my two competing career path=
s
(neither one of which materialized).
As an aside, anyone interested in why architecture seems not even to be
"artistic" anymore may enjoy architect and critic Jonathan Hale's "The Old
Way of Seeing". Subtitled "How architecture lost it's magic (and how to ge=
t
it back)", it is almost a social history of buildings, and explores why the=
y
are now so lifeless and inhuman. I read this book years ago when I was
designing my current home. I had forgotten about this book until now, and
just pulled it off my shelf and added it to my current reading pile (with
six books ahead!). From the dust jacket notes:
"This fresh and provocative book answers a question that countless people
have asked about our man-made world: How did things get so ugly? We have
all admired the natural grace of old buildings and wondered why today it
seems so hard to create their equal. We live in a time when only a gifted
and dedicated team of designers can build something approaching the beauty
that eighteenth-century carpenters could do all by themselves. What went
wrong?"
Fun digression. All the best.
