Keeps You Warm, Keeps You Sharp

Quilts, of course, are composed of tiny parts that make a spectacular whole. And when you think about it, so are mathematical theorems. But it took Elaine Krajenke Ellison to figure out that tiny quilted parts could express rainbow-colored mathematical expressions while also being just plain awesome. Shown here are but a few of her Mathematical Quilts, and I’ve included her explanations beneath each one.

clifford torus quiltClifford Torus – This work stems from work in the late 1800’s. The image of the torus results from projecting a sphere into the fourth dimension. Pioneering work on this topic was done by Thomas Banchoff at Brown University. His work, Beyond The Third Dimension was an inspiration to me, so I quilted his discovery!

mascheroni cardioid quiltMascheroni’s Cardioid – Mascheroni constructions are compass only constructions. In 1797, Lorenzo Mascheroni proved that all constructions can be done with a moveable compass alone. (One must imagine that two points determine a straight line). Napoleon was so fascinated with Mascheroni’s work, that he had the mathematician teach his French mathematicians and generals.

sierpinskis_trianglesSierpinkskis Triangle – Waclaw Sierpinski, 1882-1969, was a Polish mathematician that was very interested in patterns, including Pythagorean triples. This triangle, a fractal, was found on the floor of a church in Anagni, Italy. This oldest fractal dates to 1104. It is said that this fractal, named after Sierpinski, is the first fractal in the fractal alphabet. The quilt is owned by the London Science Museum.

the_wheel_of_theodorus_c5paThe Wheel of Theodorus* – Theodorus of Cyrene participated in the Cyrenaic school of moral philosophy. He tutored Plato and was a Pythagorean. His lifetime spans 465 to 398 B.C. During this time period the Greeks just started using written numerals. Further, the concept of the irrational number developed around this time. This quilt starts with an isosceles right triangle with sides 1, 1, and the square root of 2.

*Also note that the quilter/author appears to be wearing a sweatshirt quilted with her Sierpinkskis Triangle design.

  1. double-wow. now feel like i need to combine all those lesage visions and that crazy quilt i got at the swap into this swirling magical robe for my time-traveling dreamland adventures.

    again, thanks for the visions……!
