  • This site by Zenith Electronics contains information about the development of remote controls for televisions, covering the "first TV remote control, called 'Lazy Bones,' [which] was developed in 1950 by Zenith Electronics Corporation" and "used a cable that ran from the TV set to the viewer," the 1955 "Flashmatic" wireless remote that used photocells, ultrasonic remotes, and today's infrared remote controls.

  • The 'wires' connecting the photocells to the brain run over all the surface of the retina, so the light rays have to pass through a carpet of massed wires before they hit the photocells.

  • Imagine a latter-day Helmholtz presented by an engineer with a digital camera, with its screen of tiny photocells, set up to capture images projected directly on to the surface of the screen.

  • One consequence of the photocells pointing backwards is that the wires that carry their data somehow have to pass through the retina and back to the brain.

  • These unique features make selenium useful for photocells used to power everything from hand held calculators to large-scale photocells used to convert sunlight into electrical energy which is then stored in batteries.
