About ‘Proven Cone’ by Elke Stangl (elkement)
A digitally enhanced mathematical proof originally drawn on paper: Why circles are projected onto circles stereographically.
The circle on the sphere and its image in the equatorial plane are both connected by some sort of cone. If the circle would be the base of the cone, the intersection with a plane would be an ellipse. As the…

Elke Stangl (elkement) is an Austrian physics PhD working as an engineer. Her mathematical art is borne out of her life-long passion for the theoretical underpinnings of her craft. She is creating virtual three-dimensional structures from mathematical functions – digitally with code or with ruler and compass, using traditional techniques of descriptive geometry.
Her initial inspiration was Sir Roger Penrose’s book The Road to Reality, the hand-crafted drawings…
