Could you recover a murder victim's last sight of their killer by extracting it from the retina? Little more than a century ago, forensic scientists thought it might be possible. After all, in 1877 physiologist Wilhelm Friedrich Kühne was able to develop a simple image from an albino rabbit's dissected eyeball. (Above, the two images on the right come from rabbits who stared at two different windows. The left shows just nerves and blood vessels.) From Smithsonian:
The College of Optometrists in the U.K. reports that police photographed the eye of a murdered man in April 1877, "only partly aware of what optography involved," and that investigators on the trail of Jack the Ripper may have considered a proposal to use the technique.
Faith in optography was misplaced, however, as Kühne's experiments showed that only simple, high-contrast surroundings were able to produce interpretable optograms, Douglas J. Lanska writes in Progress in Brain Research. Furthermore, the retina needs to be removed very quickly from the recently deceased.

Astronaut David Scott re-created, in 1971 during the Apollo 15 mission, Galileo’s “falling bodies” experiment by dropping a hammer and feather on the moon at the same time. Simply, both fell at the same rate because there was no air resistance. screengrab via Wonders of Physics/YouTube (Digg)

IMGURian @KRANKARTA6 did an awesome topography visualization project in the “Ridgeline Style” that reminds us of the album cover for Joy Division’s classic LP ‘Unknown Pleasures.’
Maybe you had a piano teacher as a kid that drove you off the instrument forever. Or maybe you always wished for some serious training, but never found the time. Whether you have dreams of tossing off a Beethoven or Chopin piece at the drop of a hat or you have visions of being the […]
When you see that curved arrow on the side of a cardboard box, you instantly know that box came from Amazon. The unfurled rainbow feathers of a peacock immediately scream NBC. And a partially eaten piece of fruit in the profile is a world-recognized symbol of tech titan Apple. Icons are powerful symbols, condensing volumes […]
Call it retro. Call it a throwback. Even call it kitsch. But the 80s are still a singular time in pop culture history. From Ghostbusters and Back to the Future to your neighborhood arcade and the Atari 2600, artifacts of that seminal decade still resonate, evoking audible excitement and sighs of pleasant yesteryear remembrance. But […]
