Superconductors aren't new.

Wait, how is this different from normal superconductivity?

Isn't this how maglev trains work?

>>3923690
I think the difference is that the superconductor is being "trapped" in position

>>3923692
But it's nothing new?

Holy crap I want to become a quantum scientist just so I can do this by myself!

>Computer that can read your mind
>Freddie Mercury reborn

What? Where? When?

>>3923699
no idea, is it new? I don't follow this sort of news.

Is this what you meant, OP?

>>3923717

Nope. Freddy Mercury is reborn just not in the literal sense...there was a Canadian guy from a Christian Rock band who can sing his voice near pitch-perfect.

For the Freddie Thing

That's the one!

Don't forget this, OP.

They're actually making video games based on the mind reading thing.

It's extremely rudimentary though, it obviously doesn't read human readable sentences from your brain but it allows you to pick up stuff with your mind in the game. You can basically throw stuff with just your brain and that's cool in my book.

Something about parts of your brain being activated while thinking of something very specific like moving stuff in a direction. Meaning you have to wear this fuckugly contraption to detect brain activity.

It's a step in an awesome direction regardless of practicality.

>>3923763
Probably, like every technology advancement, ever, so will the attachment become smaller in time, probably just a headset looking...thing

>>3923771

Well the problem with measuring brain activity is that you need to have direct skin contact with the place where you want to measure activity.

Talk about a bad hair day huh.

I'm guessing we'll be seeing implants before a headset-like solution because there's just no way to measure activity accurately otherwise.

quantum locking is

The "I'm so nerdy xD xD XD" Internet confirmed for being retarded and easily impressionable.

Question: When he demonstrates the track it almost seems like the disk is keeping a steady velocity for quite some time.
Would it be possible to extract energy from this?

>>3923877
whatever energy you extract from it would slow it's spinning.

Here's another person that sounds like Freddy mercury.

Im not seeing whats so special, they aren't him.

Just found this

from this list
http://www.youtube.com/social/blog/boards-4chan-org-jp

it's another demonstration with a link to some English explanation.
>Though it is often explained that this is the Meissner effect, this statement is not correct.
>Meissener effect is the phenomenon that the magnetic field lines are excluded from a superconductivity object

I don't sprechen the mooninite but after watching the video it appears that this effects is caused by the superconductor only allowing magnet lines of force through of the particular vector to which is was chilled with.

>implying this shit hasnt been around for donkeys years

deal with it hipster trash

It is irritating enough to see this fucking video posted ten times a day, but even more irritating that people don't realize there have been videos of this for years.

confirmed for science fans

The breaking the speed of light shit was just an error in the measurements. Apparently the CERN researchers didn't properly account for relatively in their measurements, and it done fucked everything up.

Get with the times, son.

>>3924158
oh yeah, what's the effect called?
protip: not the Meissner effect

>>3924171
>[citation needed]

As far as I'm aware, your assertion about relativity has not been confirmed. There have been a number of suggestions as to why the neutrino velocity appeared to exceed c, but none have yet been confirmed, I believe...

>>3924171
no, that criticism was debunked

>>3924202

[citation needed] on both sides

>>3923877
Yes, but then the object would slow down.

Or, if you prefer, no, you dumb fuck, it's only decelerating slowly because the only friction is air resistance.

>>3924211
I wouldn't worry about it, there's millions more hyper-reflexive skeptics to go.

>>3924220

Skepticism should be the default position before shown definite evidence

>>3924225
> skepticism should be the default position
I'm not sure about that...

>>3924229

Sorry, but intelligence begets cynicism. Blind acceptance is a trait of the ignorant.

>>3924225
hypothetically speaking, yes, but most people are only skeptics when it's convenient for them.

>>3924230
I think that joke came at you faster than you can comprehend.

>>3924271

>>3924271

Ah yes, I see the wit when I step back and look at it.

It is sometimes difficult to convey in text.

>>3923729
That guy sounds nothing like Freddie.

>>3924229
I don't believe you.

>>3924323
And I don't believe either of you.
