Join us to explore the fascinating world of Art, science, mathematics and design with Prof. Emeritus and artist, Carlo H. Séquin. This cafe talk will start with a gentle introduction to mathematical knots and ways to describe and classify all possible knots. It will then focus on ways to turn such knots into attractive, abstract geometrical sculptures, using various computer-aided design tools.

In one approach, a suitable cross section is swept along the knot-curve, possibly twisting and turning as it moves along this way.

In another approach, a thin wire-configuration of the knot is used to define the edge of a nicely balanced minimal surface. This is equivalent to dipping the wire knot into a soap solution, and then observing the intriguingly complex soap-film surfaces that might form.
