In the history of magic, Jean Eugène Robert-Houdin (1805-1871) is considered the father of contemporary conjuring. (Indeed, Ehrich Weiss was so influenced by the master magician that he took the stage name of Houdini in his honor.) A lifelong maker, Robert-Houdin is credited in the late 1860s with inventing an optical device called an "iridoscope" to see details within the eye. In a description of the device from the time reprinted in the journal Archives of Ophthalmology, Houdin said that "its principle is something like that upon which a water carafe is held up to the light to detect whether the contents are pure." Above is an 1866 watercolor Robert-Houdin used the device to paint of the cataracts in his own eye. It was shown as part of a recent Robert-Houdin exhibit titled "Fascination optique" at the Maison de la Magie Robert-Houdin in Blois France. (via Cabinet)
That point of light between Saturn’s rings is Earth, captured by NASA’s Cassini spacecraft on April 12. More about the image here at NASA JPL. It reminds me of the last photo taken by the Voyager I spacecraft before engineers shut off its imaging systems. Carl Sagan had persuaded NASA to turn Voyager I’s cameras […]
As AI improves, the mystery of consciousness interests more programmers and physicists.
Most of us need a computer interface implanted in our brains like we need a hole in our head. That said, there are benefits to bridging the gap between mind and machine. Joel Murphy is the founder of OpenBCI, an inexpensive, and non-invasive, brain-computer interface (BCI) platform. People have used OpenBCI to control robots, compose […]
Even the most expensive pair of hi-fi headphones can’t match the feeling of bass rumbling through your body at a live show. That’s why music aficionados designed The Basslet, an accessory that reproduces that sensation from your wrist. Does it make your whole body shake with deep subs? Not really, because that would be terrifying, but […]

Thinking of a business idea is the easy part. Doesn’t even have to be a “good” idea, you can still get people to throw money at a non-existent venture, but to do that you need to at least have something even resembling a viable business plan. Why doesn’t anyone do it then? Because building that semi-viable […]
