1.
Which of the following mathematical concepts has been used as an inspiration?
Correct Answer
A. Algebra
Explanation
Algebra is the correct answer because it is a mathematical concept that has been used as an inspiration in various fields, including physics, computer science, and engineering. Algebra involves the study of mathematical symbols and the rules for manipulating these symbols to solve equations and analyze mathematical relationships. It provides a framework for solving complex problems and representing real-world situations mathematically. Many other mathematical concepts, such as simultaneous equations, quadratic equations, and matrices, are built upon the foundation of algebra.
2.
Which of the following techniques is naturally geometrical?
Correct Answer
B. Counted-thread embroidery
Explanation
Counted-thread embroidery is naturally geometrical because it involves stitching on a specific count of fabric threads, resulting in precise and symmetrical designs. This technique often uses stitches such as cross stitch, satin stitch, and backstitch to create geometric patterns and shapes. The counting of threads ensures that the stitches are evenly spaced and aligned, resulting in a clean and geometrically accurate finished piece. In contrast, techniques like counted cross stitch, Scandinavian folk pattern, and Ty crochet may incorporate geometric elements but do not rely on the precise counting of fabric threads for their execution.
3.
Which of the following is an example of knitted mathematical objects?
Correct Answer
A. Platonic solids
Explanation
Platonic solids are an example of knitted mathematical objects because they are a specific set of geometric shapes that have regular faces and vertices, and are made up of identical polygons. They are named after the ancient Greek philosopher Plato, who believed that these shapes represented the fundamental building blocks of the universe. Knitted mathematical objects refer to physical representations of mathematical concepts created using knitting techniques, and Platonic solids can be created using knitting patterns to showcase their mathematical properties.
4.
Who was the mathematician that articulated the mathematics of worsted spinning?
Correct Answer
D. Margaret Greig
Explanation
Margaret Greig is the correct answer because she was the mathematician who articulated the mathematics of worsted spinning. The other options, Rose Helen, Sandra Holmes, and Patt Robinson, are not associated with this specific field of mathematics.
5.
Which of the following mathematical ideas is used in quilting?
Correct Answer
C. Conic sections
Explanation
Conic sections are used in quilting. Conic sections are the curves formed when a cone intersects a plane. These curves include circles, ellipses, parabolas, and hyperbolas. In quilting, conic sections are often used to create curved shapes and patterns in the fabric. Quilters may use templates or rulers with different curves to cut fabric pieces or to create quilting designs. The use of conic sections allows for the creation of intricate and visually appealing designs in quilts.
6.
What do we use to craft the Lorenz manifold and the hyperbolic plane?
Correct Answer
B. Crochet
Explanation
Crochet is used to craft the Lorenz manifold and the hyperbolic plane.
7.
How did Ada Dietz define weaving patterns?
Correct Answer
B. Expansion of multivariate polynomials
Explanation
Ada Dietz defined weaving patterns as the expansion of multivariate polynomials. This suggests that she used mathematical equations involving multiple variables to describe and analyze the various patterns that can be created through weaving. By using multivariate polynomials, Ada Dietz was able to capture the complexity and intricacy of weaving patterns, allowing for a more comprehensive understanding of this art form.
8.
Which part of the weaves does the embroidery technique use?
Correct Answer
B. Natural pixels
9.
Who was the mathematician that collaborated with Dai Fujiwara?
Correct Answer
B. William Thurston
Explanation
William Thurston was the mathematician who collaborated with Dai Fujiwara.
