The MagSurf is a levitating skateboard based on the principles of superconductors. It was built by scientists and students in the Laboratoire Matériaux et Phénomènes Quantiques at Paris Diderot University.
The video is older, but it turned up recently in a really interesting blog post by Kyle Hill that does a fantastic job of explaining how superconductors work — and why you can create a floating skateboard, but you're stuck using it in conjunction with a track.
Instead of putting a magnet above a superconductor, you can put a special kind of superconductor above a magnet and “pin” it in space. Type type-II superconductors, like the one featured in this now viral “quantum locking” video, are superconductors that also expel magnetic fields from their innards, but not perfectly. These superconductors are thin enough for flaws in the material to allow small “flux tubes” or “quantum vortexes” to leak through. When that happens, it’s like suspending a pincushion on a bed of nails—the superconductor is locked in space.
Gravitational waves are real, and scientists have detected them. In the video above, PBS Space Time explains the discovery by researchers at the Laser Interferometer Gravitational-Wave Observatory (LIGO). From the New York Times: A team of physicists who can now count themselves as astronomers announced on Thursday that they had heard and recorded the sound […]
Evil Mad Scientist Labs have released their latest set of nerdy Valentines ready for you to print, glue on cardstock, and use to win your true love’s heart.
“Bentonite Me Baby” is a brand of “detox clay” that you spread on your face, or eat, to rid your body of mysterious, nonspecific “toxins.” It is full of lead.
If you’ve been blessed enough to avoid them yourself, you’ve definitely heard the horror stories. Late night, crushing out a ton of work, writing, coding, anything, then boom – your computer crashes. The battery blows, you spill water or coffee all over the place, or it just shuts down with no explanation, and you’re screwed. […]
You travel around a lot. It might be that jet set life from New York to LA to London to Tokyo, or it might be back and forth from the coffee shop to the office, or from the kitchen to the couch. Any which way, you’re mobile and that’s the way to live. When you […]
It’s 2016 and we like our technology really small. Our phones fit in our pockets, our remotes are lighter than ever, and even our cars seem to be shrinking. So your new drone shouldn’t be an exception. This Axis VIDIUS Drone is 21% off right now and it’s so little, your biggest problem won’t be […]
