Oh look…magnets.
Awesome. 175 thumbs up and 1 thumb down. I feel sad for the forever alone person who actually gave this a thumbs down.
it was only a thumbs down because they flipped it over and locked it in place.
That my friend is a comment FULL OF WIN. Well done you
F*cking magnets; how do they… oh, what’s the point?
Someone get in touch with the mormons and get them to explain how this thing works.. and how close I am to the hoverboard I have been dreaming about since back to the future 2
er… Magnets don’t allow for the adjustment of an object at the Z axis of the universe – only X and Y – it will pull or push, magnets don’t allow for the adjustment of say, 1 inch to 2 inches above the magnet, as they show in the movie.
The way I understand it, those are, as they say in the video, superconductors, which create a very strong magnetic field. The piece that’s being levitated changes the magnetic field, but the field alters itself accordingly and can “memorize” the alteration of itself, which means that once the object is in place, it will stay there unless it’s moved. I’ve had a student of superconductivity explain it to me some time ago, but I might recall it incorrectly.
Anyway, the basic idea is about magnetic fields, which means that it’s very close to magnets.
wrong way round, the superconductor does not create a strong field, that is provided by the permanent magnets on the ring and thing the person holds. The superconductor is effectively repelled and attracted to the magnets in equal amounts so levitates at a fixed distance
Other than that you are fairly close, the memorisation it not that good an analogy for explaining but the full explanation is more complex
Science boner!
I call it… a scigasm.
I call it… a nerdgasm.
good call…
I call it… Israel being one step ahead of the world. As it should be.
Now figure out a way to do this without the liquid nitrogen, and make the earth more than 20% cooler!!
20% cooler! I’m freezing my ass off as it is. Make the winters go away!!! please!!! (except for Christmas, it may snow at that day)
Please don’t tell me you actually don’t get the reference.
why isn’t everyone at that freaking science center looking at this masterpiece!?!? is there a time-machine taking-up their time or the cure for cancer somewhere!?!? we’re going to have flying cars, soon, dammit!
Actually, the time machines takes up no time to visit, if you think about it.
^ ROFL
Time travel doesn’t work. Why haven’t we seen anyone from the future yet? Are these ages just SOOO extremely boring, that those billion peoples in the future who have such machine, just didn’t care to visit?
I suppose there’s a really simple solution:
Whoever will travel back in time will lose everything what he doesn’t bring with him because the present will be altered so his future will never exist anymore. So either no one dares to or everyone who does doesn’t want anyone who’s at his destination know of it.
Except, by definition, you cannot alter the past because it has already happened
Anyone who travels back in time is traveling to a past that has already occured. They have already been there BEFORE they travel back (potentially before they were born) and every action they take has already occured. They cannot change anything in the past because everything they’ve done has already happened.
I personally don’t think time travel is possible for the same reason as Peter Van Dam (and I remember Steven Hawking saying the same thing): “Time travel might be possible. But, if it is, why are we not inundated by travelers from the future?”
Time travel forward is possible due to relativity, but not backward.
I am time traveling every second of my life.
People assume that time is a strict progression of cause to effect, but actually from a non-linear, non-subjective viewpoint;
it’s more like a big ball of wibbly wobbly… timey wimey… stuff
Implying there are billions of people in the future, maybe they all died. =)
I LOVE science. That is just too cool [bad pun].
THAT’S SO F*CKING AWESOME!
O_o My brain hurts…
Am I the only one who watched this and said, “Oh yeah! One more step closer to my back to the future hover board!” in his head?
Anyway, yeah keep at it science!
Dear scientists: you have 4 years.
Frictionless mag-lev train in the works yet? Well, I suppose it won’t be entirely frictionless, given that it’s surrounded by air…
Air could be removed in a vacuumed tunnel for the train to travel through.
If you create a vacuum tunnel in which the train drives in, you essentially have a frictionless train.
while a vacuum tunnel might spare you the friction of wind resistance, you still have the friction of the wheels on the tracks, unless you’re using mag-lev. you’re not ready to drop out of science class yet, kiddo.
They WERE talking about a mag-lev train.
I think it’s cheaper and more energy efficient to just supply the train with more energy rather than making a vacuum tunnel. The vacuum pumps need energy too.
I bet you $1,000,000 someone is going to completely miss the point of your explanation by ignoring the obvious. Then call you chief or something dumb like that.
hahahaha.
The energy used to maintain the vacuum might be larger than just moving the train, and/or making a tunnel that can withstand being depressurized like that would need to be so strong it wouldn’t be cost efficient.
Not to mention safety hazard for the people on the train. If a train door-seal were to crack…
with the vacuum tunnel, we’d be able to keep the tunnel clean, too! Good thinking, chef.
Wow, this is seriously cool. And to think I thought I had become bored of maglev tricks.
Magnets, how do they… yuck, even I can’t type something that ancient.
Hipster!
It’s science, you can’t explain that!
Chinese have ha one in commercial operation for 7 years now.
http://en.wikipedia.org/wiki/Shanghai_Maglev_Train
Not exactly, this is quantum locking, not simple magnetic field manipulation. It’s different, and considerably more interesting while a maglev tracks function by changing the magnetic field to attract/repel an object, this works by holding an object steady in a magnetic field that remains constant. not sure if it’s practical or feasible for anything beyond this trick, but it is a considerably different technology.
lol, buyed from the germans, cause the germans got no balss or money do build something they invented…..
SOOO cool!
This is in my hometown. While this was going on, we stopped at the Baltimore Convention Center for a potty break, not imagining what wonders lay within.
Tel-Aviv is in Isreal. I dont see how you could have visited the two places at once during the same time frame. And dont give me a load of bs saying that you went from Tel-Aviv, Isreal to Baltimore, Maryland, USA just to use the bathroom.
Dunno, but when i googled ASTC 2011 , the location was Baltimore Maryland and not Tel-Aviv Israel

Magneto striked again!

SOMEONE GAVE IT A THUMBS DOWN!?!
That must have been an accident.
How do magnets work?
Fake .. I can tell by the smoke ..
The guy wasn’t using any gloves while he working with the liquid nitrogen.
I’m not saying this is fake but its kind of weird.
Not as weird as it seems. I work with liquid helium and liquid nitrogen a lot, and you can definitely touch something like that with your bare hands, as long as 1) your hands are dry and 2) you’re quick. You’ll notice he mainly just taps the thing, with no prolonged contact. And even if he held it for too long, he’d just get a minor cryoburn. I’ve gotten worse burns in my kitchen than I ever have in a cryolab.
It is okay to touch it as long as oyu don’t keep it in your hand. Touching it only for a few seconds at a time doesn’t burn your skin.
Z0mg UFO Technologyyyy
It’s called “Meissner Effect”, and for those who are working with superconductors every day, it’s not really impressing, and it’s neither wizardry nor diffcult to achieve. Just get a good superconductor cooled down below its transition temperature, a magnetic field and you’re done.
http://en.wikipedia.org/wiki/Meissner_effect
Excuse me sir, you mispelled “Mass Effect”.
Meanwhile, several dozen miles away, Palestinians are teaching that Mickey Mouse is a Zionist conspiracy, and are blowing themselves up at checkpoints that allowed other Palestinians to WORK in Israel.
A thousand Palestinians worth one Israeli, INDEED.
That’s just because they forgot to supercool their magnets.
This is absolutely the right place to get into a Israel/Palestine argument! Good job!
What does the cooling have to do with experiment?
I haven’t checked the particular technique here, but normal magnets don’t work that this
This kind of effect is made possible by what scientists call “superconductivity”, which is basically a property, just like ferromagnetism. Although, the materials that we use to create “superconductors” have to be cooled so the effect “kicks in”. For example, such materials are considered “high-temperature superconductors” if the effect still takes place above 30 K (= – 243,15 °C, = – 405 °F).
Is it just me, or did it sound like Jeff Goldblum was behind the camera?
hahaha I totally thought that too, good to know I’m not imagining things!
Life will uh uh find a way.
I can almost taste hovercrafts in the near future, but I will likely be in my 50s TT.TT Floating wheelchair…..:D
-donuts- Wheeeeee!
That’s sure awesome, but nothing really new. Saw that live like four years ago… So anyone hoping for flying cars with this technique: There is still a very very long way to go.
Does anyone else think the guy behind the camera sounds a lil like Jeff Goldblum?
This is the Devil’s work. This sort of experimentation should be banned. No good Christian would ever try such folly. Praise be to God, not the lie of so called science.
Do you have electric lights? Do you have a frig and freezer to keep your your food from spoiling? Do you drive a motorized vehicle?
I KNOW you use a computer! All these inventions come from the intellect of God’s greatest creation, mankind. God gave us an intellect and the ability to explore and understand science, which only gives us more appreciation of His handiwork. The more we learn about and develop science, the more we are awed by the Great Creator of the properties that allow these inventions.
God and science go hand-in-hand. Science is only a way of better understanding the magnificence and glory of His universe. I challenge you to check out how God and science come together in harmony, Google: astrophysicist Dr. Hugh Ross’ “Reasons to Believe” site.
THIS
NEEDS TO BE INSTALLED
IN EVERYTHING
I sense an O’Reilly/Tsoukalos double team meme here.
that floating donut looks tasty
Since when did white fudge covered oreos start doing that?!
I freaking want one!
With this knowledge i will for-fill my lifetime dream…
The Weeping Angels are quantum locked
ummm u guys r missing the point. the only magnets are on the track not the part floating that is just a piece of metal. the real point is whatever is on top(probably liquid nitrogen or sumthing else),cooling the surrounding atoms (the magnetic field) and superconducting them so it locks in place. p.s. thats what i think dont reply saying how stupid i am i just cant remeber how it works off the top of my head. oh, and aliens probably fly spaceships using earth’sgnetic field, just sayin.
It used to all be done with velcro and mirrors… and now, it’s magnets and mirrors.
So the Israelis can achieve THIS, but peace with the Palestinians is too hard?
So THAT’S how David Blaine does it… hmmmm.
WAAAAAAAAAY cool! lol
