Resonator :

The show responds to the nature of the Box itself - in its
dark enclosed interior Friedlander has created an installation
about light and waves - with inspiration from the great
physicist Max Planck's groundbreaking idea about the
emission of electromagnetic radiation.

Challenged to design a better light bulb, Planck thought
about how light was emitted from a hot object.

Imagine the object in the form of a hollow ball with a hole
in it where light can enter or escape - a 'resonator'. Planck
calculated how waves would vibrate and then escape through
the hole and his resulting theory about light being emitted
in quanta turned classical 19th century physics upside down,
laying the foundations for the puzzling world of quantum mechanics.
