[Closed] Any sufficiently advanced technology is indistinguishable from magic

Awesome 🙂

For those of us with no youtube access?

It's a video of Quantum Levitation / Meissner effect.

This explains the physics: http://www.quantumlevitation.com/levitation/The_physics.html but the video is considerably more compelling than the words 😀

WITCHCRAFT!

This is going to totally revolutionise the plane / conveyor belt question!!

*Picks up jaw from floor*

I saw a floater at work today. Was'nt impressed as you lot.

Levitation? Pfff..

It might even make me buy an Android phone 🙂

If that disc thing is so cold, how come he's able to touch it without getting burnt?

S'bloody amazing though in't it. All sorts of applications once they get any problems and glitches out of the way.

I actually need this technology for my Top Secret Elfincraft which uses Elfinmotion...

For clubber: It's like a machine wot does Rubik's cubes.

[edit]hang on a minute... that's made of LEGO! That is magic! 😯

Yup, it's middle aged man LEGO (NXT?) as it's well expensive, but LEGO nonetheless.

I could watch that more or less all day.

Assuming it's cooled with liquid nitrogen (which boils at 77K), it'll be considerably warmer due to the surrounding air. The frost and vapour coming off it will be a mixture of liquefied air reboiling and water freezing/condensing on or near the surface.

I regularly handle stuff that's been sat in a bucket of liquid N2 for a while, and so long as you don't grip it for prolonged time periods, you won't get a cryogenic burn.

There's a difference between temperature and heat, and heat transfer from fingers to objects is surprisingly poor especially when you have a subliming solid trapped between you and the cold thing.

Its all done with wires

The Rubix cube thing is insane, but the Quantam Locking just blew my mind.

The Rubiks cube machine was on telly a while ago, it was made by some of the guys at ARM, who design the processors in the phones... which is why it's running on an Android phone.

But more cool than everything else, is the guy who levitated frogs... I believe he even got an igNobel prize for it too, and then subsequently went on to win a real Nobel prize as well!

The video about Quantum Levitation / Meissner effect is amazing. Could that technology be used to create more efficient motors and stuff?

play with this at work 😀

super conducting motors/ generators are rapidly becoming big business - quite popular in wind turbines at the moment.

Hover-boards by Christmas! Woot!

Any more info on real world uses?

Very interested in

You're aware that frogs can jump?

Here's the levitating frog:

And for bonus points here's some freaky ferrofluid:

Suddenly, the T-1000 doesn't seem so advanced!

Any more info on real world uses?

super conductivity?

currently lots of work involved in superconducting cables (for power station to industry scale Wattage), super conducting motors and generators - both because the size weight can be significantly reduced. some one mentioned recently a reduction in engineering costs of 60% on wind turbine projects, due to the increased output of a smaller generator means smaller blades smaller column for the same output.

MRI scanners use super conducting magnets, of course...

More realisticaly same size turbines, much bigger output, thus fewer turbines and sites needed? The opposition seems to be to turbines in general, once they're approved they may as well be big.

For magic inspired tech you can't beet the indian rope trick, basicly a rope to be held in compression, it was done by swaping the rope for 5 solid sections, attach the lowest one to an off center wheel/cam thingy and the 'wave' traveling up the solid setions canceled each other out to keep them steady, but the joints transmitted it up the column keeping it upright, so as soona s it wobbled it counteracted itself and steadied again.

Wow. That first video is cool.

ok that liquid metal thing has scared me 😯

can we close the thread, its all getting too judgement day, were all doomed, the machines will take over!!!

Well, Skynet already exists...
