New research from the Netherlands explores a placebo effect around high-definition TV. Of course, HD does look sharper, but the mind apparently can easily be tricked into thinking that regular TV is HD. From New Scientist (Wikimedia Commons image):
Sixty people in turn were shown the same video clip on the same television. Half were told to expect clearer, sharper pictures thanks to HD technology: an impression backed up by posters, flyers and the presence of an extra-thick cable connected to the screen. The other half were told to expect a normal DVD image.
Questionnaires revealed that the people who had been led to expect HD reported seeing higher-quality images. "Participants were unable to discriminate properly between digital and high-definition signals," says Lidwien van de Wijngaert at the University of Twente in Enschede, the Netherlands, who carried out the study with colleagues from Utrecht University...
The results of the experiment might have been different had it taken place in North America, though, where conventional television uses the NTSC instead of the PAL technical standard. Picture quality is lower with NTSC, "so the difference compared with HD is much larger than for Europeans", says van de Wijngaert.
Behold, the Blue Marlin, a “semi-submersible heavy lift ship” that is capable of hoisting and transplanting other, full-sized ships (that is ships as big or bigger than a US Destroyer-class vessel) all around the oceans.
Mister Alphabet is an action-figure designed to cleverly bend and contort into every letter of the Latin alphabet; the website is long on trademark warnings and arty Instagram photos, but short on details, like, “Is this an object of commerce?” and “If so, where does one buy it?” (via Kottke)
Phone chargers usually only deliver a few volts of juice at a feeble amperage, but they’ll deliver a lot more if you give them the chance. The BBC writes that a UK man died in the bathtub after being shocked by a charger connected to an extension cord. Richard Bull, 32, died when his iPhone […]

You know the drill. You go to the dentist and they ask you how often you floss. You lie through your teeth and say, “every day!” (Bonus points if you have some cilantro or chives stuck in your gums from lunch). You don’t want to keep up the charade any longer, but rubbing that tiny strand […]
The Raspberry Pi Foundation has done outstanding work packing a fully capable desktop computer into a package the size of a deck cards—especially one that only costs $35. But if you already have a working laptop, why should you care? Oh, how much you have to learn. Besides operating well as a compact digital media hub, […]
