Mathematical Sculptures by Alex Feingold
I have a strong interest in sculptures, especially those related to mathematics, and
I have made some in stone, bronze and wood. Here are links to webpages showing my work,
and links to the artists who have inspired and influenced me. You can also follow the
following link to an
Artist's Statement
which I have written.
The 11th annual Bridges conference will take place in the birthplace of M. C. Escher,
Leeuwarden, The Netherlands, July 24-28, 2008, with a Mathematical Art Public Activity Day
on July 29. These conferences are a literal bridge between mathematics, music, art,
architecture and culture, and include an exhibition for 2D and 3D mathematical art. I have
submitted four of my sculptures for the exhibition, hoping that they will be accepted
and that I will attend the conference and participate in the exhibition. The following link
to the conference website has many interesting links to previous conferences, and to
mathematical art on the internet:
Bridges Conference 2008.
One of my sculptures was exhibited November 1 - 4, 2007, at the Center Gallery at the
University of South Florida, Tampa, FL, in an exhibition ``Rhythm of Structure: Beyond the
Mathematics", curated by John Sims as part of the conference
Knotting Mathematics and Art:
A Conference in Low Dimensional Topology and Mathematical Art. You can see pictures I took
of the pieces in the exhibition, and pictures I took at the conference, by following the link:
Knot Art Conference Pictures.
Four of my sculptures were exhibited May 3 - 24, 2007, at the
Altered Esthetics Gallery
in Minneapolis, MN, during their show ``Art For The Other Senses". A write-up about the
exhibition which mentions my kinetic sound sculptures can be found at the following link:
Altered Esthetics Exhibition in vita.mn story.
Kinetic Sound Sculpture
inspired by the work of Harry Bertoia.
Stone and wood sculpture projects
inspired by Helaman Ferguson.
Bronze metal sculptures
made as castings of earlier works in other media and by welding.
Steel and plastic sculptures
inspired by hyperbolic surfaces and the tensegrity sculptures of
Kenneth Snelson
and
John Robinson.
I have also collected some beautiful examples of
netsuke.

I am president of our local chapter of Phi Beta Kappa, Psi of New York.
Phi Beta Kappa is the oldest and most prestigious liberal arts honor society in the country.
The link above will take
you to our webpage which has information about the history of the society,
our selection procedures, and lists of students who qualified in recent years.
I have been a serious ice skater (figure skating, not hockey!) since 1968. I am a member
of the United States Figure Skating Association, the Professional Skaters Association, and
the Binghamton Figure Skating Club.
The link above will take you to a webpage where I have put my skating resume and some pictures.
