This piece is representational of a living system through items which are far from living. When combined in a specific configuration, it is "alive" — much like a nervous system. A deep thumping emits from the speaker, beating at 1.5 HZ, the average BPM of the human heartbeat. When approached, the beating speeds up, reactively. As if this artificial nervous system is aware of your presence.
Simultaneously to the mechanical oscillations of the human heartbeat, electrical signals are traversing our neurons and nervous system at extraordinary speeds — this is shown in the wirelessly lit fluorescent bulbs. The bulbs are being lit up (excited) by a transformer, stepping up pulsed DC voltage into high frequency alternating current. This transformer is called a Tesla Coil. I calculated on the installation floor that the electricity is oscillating at 542 thousand hertz (542KHZ), hence the title, 1.5HZ/542KHZ.
These systems are symbiotic — one cannot exist without the other, similarly to our own physicality and existence. Your heart beats at roughly 1.5Hz, this fuels the firing of neurons in your brain, 'beating' much faster.
