The drawing illustrates how a rotation by 720° can be undone, in a way a 360° rotation can't. Dirac's Belt Trick also goes by the name of "plate trick, and it is usually introduced in relation to spins in quantum mechanics. But the trick shows that the topology of rotations in 3D space is generally weirder than one might think.
"Dirac Sea" is related to an interpretation of an aspect of Dirac's theory of the electron before the electron's antiparticle had been detected. What became the positron was once interpreted as positive holes in a sea of electrons.
Watercolor pencils, watercolor markers, acrylics, gel pen on A3 paper. I've staged my own belt and kilogram weight.
Elke Stangl (elkement) (she/her) 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.. Read more…
