What is Quantum Tunneling?

[FreeOpenTutorials]

ughhh....yes o.O

[HeyyLookItsAlex]

What if you consider (dropping the ball; having it not go higher than where it was dropped without an extra push) that you count the highest point the ball can reach as the same point when it reached terminal velocity? Would the ball go higher than that point?

[Ramsez]

that's so good for the electron.

[kamikaze69penguin]

well...that happened

[6Njames]

i love these videos my friend, although i wish you would make them a bit more in depth and longer but still, your putting the info out there in a way most "average" people can understand. keep this going. Knowledge = power.

[RockOnHakan]

what? that's crazy. can you make longer videos? explain all of this more in depth...

[Permpipat1]

I try to understand this stuff....but my brain hurts.

[muntoonxt]

I would like it if @minutephysics made a @tenminutephysics so they could actually explain this.

[CloudysGuitarChannel]

Electon in the nucleus? *brain explodes*

[RomanNumural9]

ohh i get it... wait where'd my arm go?

sigh not again! -_-'

[HandMane]

Awesome: the electron saying "Hey guys!"

[mediczjeee]

wat?

[benbennit]

It's all about scale. And fractal effects on nature at those scales.

Audio speaker frequency on a board covered in sand makes similar complexity and symmetry. And it all happens at different scales.

[redryderbbguy]

Today my science teacher asked why i looked so tired. So i explained to him how i was watching muinite physics video's on schrodingers cat and what is fire, e.c.t.

Essentially, he thinks i am a genius

[joshdaugherty1111]

so wait a second, is there any evidence for this or is it just "lol its possible!" i mean its like saying, "lol you can wake up on mars one day w/o doing anything lols"

[klakkaros]

@joshdaugherty1111 There is lots of evidence, and it isn't yet fully understood. Without quantum tunneling, nuclear fusion wouldn't be possible! I.e. no sun, so no life. Amazing stuff :)

[thechosenonedman5176]

@joshdaugherty1111 Actually, you're understanding this quite well.

Please look up the double slit experiment if you'd like some clarity.

[nicholaswright2006]

@joshdaugherty1111 You're thinking in macro. I think minute physics explains why macro stuff doesn't behave like quantum stuff.

[TheOptimalmale]

thank you! used this for my presentation and got a 100

[LightLink1992]

can u make a video about positrons?

I heared bout it but dont really know what they are

my physics teacher is to dumb to explöain (no seriously she told me she doesnt know)

[Walnuss]

The electron orbitals around the nucleus give you the probability of the electron to be found there. When you look at p-, d-, f- or higher orbitals, the probability of an electron to be located in the nucleus is 0, right? And in an s orbital the electron CAN be IN the nucleus?

Can anybody enlighten me on this topic?

[ricktbdgc]

@Walnuss you know heisenberg was a true genius, he basically created a theory that everyone can agree with.. uncertainty... duh Hey anything you cant figure out fall under the uncertainty.. it says anything is possible so you dont need to stress about weird results anymore, hey lets just give up and say the universe cant be figured out if everything so uncertain, fuck that..

[TheMonkeyWithTheHat]

OR Throw the ball instead of dropping it.

[hello2sup]

great vid simple and on the money.

[StrayzKid]

or the cat !

[StrayzKid]

something about hairy balls?

[Emrekpelmu]

That electron gets ALL DA BICHEZ

[TheJordanHartt]

My balls sure like it in her valley below.

[santoslittlehelper06]

So basically, everything could be anywhere.

That explains why so many people have their heads up their arses.

[porchemasi]

Mind = Blown.

[BannedUfos]

So with antimatter you can sometimes find matter in it.

[JstaGoodoBoy01]

Why even go to class, can't i just watch youtube videos

[livedandletdie]

Ok guys but how does the electron get out of the nucleus if it's in the middle? ...Velocity.

[DallasEpicness]

Turn on captions. LOL

[guillaumefont]

Well... yes an no : you can't mix the two models. If you're considering your physics as probablistic, there is A CHANCE that your e- is in the nucleus, but you'll never know. You can't infer that sometimes it's there. You can just assume that there's a chance...

[rocker223rock]

The electrons, which have a negative charge, could only pass throught the space between the atoms because the repulsive force of the electron shell would deter the electron from being able to even reach the nucleus.

[123456789Viewr]

Then the atom explodes because it would be so unstable.

[igorhb]

Now you're thinking with portals.

[AsianHitman1]

LOLWUT?



[TheSeventhChaos1]

@AsianHitman1 agreed...

[CoolCat123450]

There should be a movie based on subatomic particles. It defies the odds.

[1bress1]

but you would know how fast its travelling :P

[mrboredom020]

My earphones fell off my ears after watching this

[turkishdisco2]

i still don't think that explains it.. i'm none the wiser after watching this. maybe you should make it '2minutephysics'

[NeverSegFault]

Electrons inside the nucleus? Mind = blown

[Abaraxus789]

I got here through Portals....

[3KS26]

@minutephysics

Would this recorded event be considered Quantum Mechanics? ( /watch?v=lF8w3zN0xiA )

The ball looks as if it were magnetized to the rim and then just sits there for a couple of seconds. If it didn't happen on live TV I would've thought it was fake because its so weird.

[Foxtrot202]

start doing 2minutephysics. hell get crazy, do 2.5

[Kukkaloota]

An easier way to understand this:

We've a bottle of beer which we did buy from grocery.

We want cold beer so we put it in to the fridge, right?

But what happens, when you shut the fridge's door?

There is almost infinite small chance that the bottle vanishes from the fridge and appears somewhere else in the world.

Or something like that if I remember correctly what those physicists told us while we had an excursion to CERN.

[MadeOfCATS]

...

What?

[VladimirZharkov]

@Craftman368 that's quantum mechanics for ya

[Craftman368]

I've watched this many times... and I still don't have a clue of what this guy is talking about.

[Creative360Studios]

and yet quantum physics is still more understandable than school

[everythingman987]

Dear Lexus, IDGAF ABOUT HOW MANY DAMN DATA POINTS ARE ON YOUR CRASH TEST SHIT I WANNA WATCH mituetphysics

[QuantumRelease1]

So this is why i can't find my wallet.

[lu1scantu]

@QuantumRelease1 I lost mine too, I had $586 in it. :(

[DrZudsi]

We learned a little bit about that in chemistry class... still mind-fucks me...

[Alas07X]

sorcery.

[kylerreinhold]

My head hurts, yet I still watch your videos.

[alex4sarabia]

da fuuuuq

[Tanmark1998]

what?

[piecharthosen]

And I thought that the uncertainty principle only argued that the electron could be anywhere 'orbiting' the nucleus. now it can inside the nucleus? aieee *asplodes*

[aceytam]

what a boss electron

[RRYtbea]

so uh... what's quantum tunneling??

[emikochan13]

@RRYtbea when a particle is on the other side of something it should be. It has "tunnelled" through the object. It's the reason fusion works and the sun shines :P

Normally those hydrogen atoms can't get close enough to fuse because of the repulsive charge, but sometimes they probability into the centre of another atom, performing fusion.

[0909umcia]

@RRYtbea So, quantum tunneling consists in the fact that the particle can overcome an energy barrier, which supposedly should not be overcome. It is unlikely, but possible.

[meayell]

I don't agree.

[kremzik]

wat

[Entertanmentfoyou]

his videos are educating and entertaining

[pikurown]

Is this quantum non locality? I wish I was 10 again and found these little minute pays ifs. I love them all I like to paint conceptual physics. It is beautiful

[euducationator]

@pikurown I completely agree

[pikurown]

@euducationator I watched all of your minutephysics and the lecture you gave about making the videos. I just want to say they are stellar. I would bet that these little snipets are capable of having people get over the hump of a difficult concept Thanks for all of that and I look forward to more.

[euducationator]

@pikurown what? huh? were you talking to me? because i havent posted ANY videos yet, I just created this youtube account.

[xavy83]

My brain just popped

[chaoslord108]

my impression of quantum physics at the end of his video? complete bullsh*t

[ScorpiaX]

@chaoslord108 And without quantum physics and mechanics, you wouldn't be here with your desktop/laptop/tablet phone commenting this video.

[chaoslord108]

@ScorpiaX and yet i cannot quite help but thinking that a ball will randomly teleport into a mountain, just because we cannot see it.

[pikurown]

@ScorpiaX actually quantum mechanics is not about a state of being it is a concept in physics that is cool

[BatspindaVL]

Cool story bro.

[ambrosiathe1]

But whyyyyyy?

[kevincap13]

ill never see chemistry the same again.

[bloodypirates247]

Quantum physics basically proves that you can't prove anything... wait a second... x.x

[DCM0Dz]

I have a question when are quantum physics used in the world? not trying to be a smart ass im acually curious...

[highwayblowout]

@DCM0Dz It's just to fuck everything up when you think you got a clear answer of something.

[TheRinzl3r]

@DCM0Dz Nanotechnology, Energy production (Nuclear energy) are 2 immediate ones.

[pikurown]

@DCM0Dz they are cool people who get to play with the most exciting toys. Like the one in cern that 25 mile circle with a tube in it that shoots electrons and has just about cancelled out Einstiens theory of relativity and shows that it may be very possible to time travel....Welcome to the past and see you in the future....baby

[Mal7815]

Can someone help explain better please... I don't understand how this is possible at all. I also don't get how an electron could end up in the nucleus of an atom.

[MetalicAtheist]

@Mal7815 With quantum physics, everything is probability. An electron could be anywhere in the entire universe. literally millions of lightyears away. But it's so improbable that it will never happen. This also means it could be inside the nucleus. Also improbable, but it does happen. An electron at the lowest energy level has the highest probability of being within a certain radius- thus, a sphere. That's Bohr's radius by the way.

The whole basis of quantum mechanics is "anything is possible."

[TheRinzl3r]

@Mal7815 Say you roll a dice. There is a 1/6 chance you roll a one. It's unlikely but possible. Say the chances of an electron in a nucleus are 1/Gazzilion (I know it's not a real number, i'm using it as a metaphor) . Unlikely but possible.

[pikurown]

@Mal7815 it is possible in quantum mechanics just like it is possible that all the atoms in your head would fall apart the next time you wash your face and fall into the sink with the water- but the possibility of that is sort of like the same for Elvis to walk on the moon in 2012 while lip sinking his youtube videos. Does that help? If not go to a quantum mechanic. They can tell you better.

[12529kg]

For those who are confused ignore the ball and the valley.

He's trying to talk about electrons. If you know atoms you know that protons (positive) and neutrons (neutral) are in the nucleus of an atom and electrons (negative) are whizzing around the outside, but because of the magnetic force between the protons and electrons the electrons actually want to be as close to the protons as possible.

So even though it's rare, sometimes an electron is pulled inside the nucleus, even though traditio

[superchickenbob]

im really confused, lol. can anyone explain why the ball could end up on the other side of the mountain? is it cuz the ball is taking energy from the other side or something?

[1337meister1]

@superchickenbob it's not a ball...it's a particle. And it's not taking energy from the other side, it's probability. It's probable that the particle could end up in the valley but there is also a very small probability that it could end up inside the mountain or even on the other side of the mountain.

[superchickenbob]

@1337meister1 not to be mean or anything, but u just pretty much said exactly what he said

[felrece]

@superchickenbob I think he's trying to help us understand what Quantum Tunneling is about. He's saying that traditionally a ball would not roll higher than the point of which you dropped it but in quantum tunneling (symbolically a particle according to the comments) it could be in the valley of which you dropped it... or the other side of it. Basically he's saying that quantum tunneling = a freak accident.

[pikurown]

@superchickenbob When you plug in the tv it can be turned on cause all the electricity is traveling through a wire. Quantum particles don't need wires. They are smart and can act strangly. They also do not need rules or organizations. They are the rock stars of the universe. If they want to propel head first through a mountain so they can slide down a mt they can do it. It would be more probable for you to jump to the moon, however.

[1995usar]

How is it that the atom can be in the nucleus, & how does it affect it.

[chrism4n14]

@1995usar I don't think an electron actually can affect the nucleus, because its moving so fast, chances are its only going to be in the nucleus for a fraction of a millisecond. But the only way it could, im guessing, is if the electron pushes the protons out, meaning the electromagnetic forces holding the nucleus together would weaken and could possibly cause the nucleus to blow up or decay or whatever.. Then again i doubt thats actually the case,

[chrism4n14]

@1995usar Also the electron can fit inside the nucleus because it is so small, it basically has no mass.

[pikurown]

@1995usar Well if that happened we would need chaos theroy to straighten out the known universe. I guess you could say the unknown too.

[Mr007eds]

does that mean the ball can kick me at some point ?/ ooo..... wait no i mean possibility or quantum stuff

[gaeta34]

Wait so Do i get to keep the ball?

[Chainmail]

wtf...

[SamyAdel9]

Now your thinking with portals...

[SamyAdel9]

videos=food for my brain

[XenClan1]

...what?

[AruhiTheGreat]

Don't you find electrons in the nucleus after basic Beta decay anyway though...?

[SushantBhargav]

electron is such a perv :)

[ChikoWhat]

We put 'this' much effort into rolling the ball into the valley, but sometimes the ball(should it have a personality) will give itself an extra push to be in a better place(More confy inside the nucleus for eg. :D)

[Dagg215]

0:13 Why don't we throw the ball over the mountain?

[MorbidSkateFrenzy]

@Dagg215 because were all lazy assholes

[MorbidSkateFrenzy]

@Dagg215 because were all lazy assholes

[TheRinzl3r]

@ShiroHero13 Quantum Tunneling. Did you not just watch the video?

[TheDivineWinds]

This may need a slightly better explanation, since I didn't see what "quantum tunneling" was from this description.

[tubester4567]

@TheDivineWinds Liek, the particle tunnels through the mountain instead of going the most obvious way over the top of the mountain.

[AllynEntertainment]

Now your thinking with portals

[Bella8236]

I wonder how many black markers he's used up to make all these videos.

[squidsaresquids]

Whatttttttt i zoned out for 2 seconds and didn't get the rest

[MrElectricApples]

スマートな私は行うためありがとうございました

[ZaneIsRandom]

Quantum physics, basically teabagging every physical law EVER

[euducationator]

@ZaneIsRandom what? it deos not! the very small and very big things in the universe just play by completely diffrent rules, maybe the particle sends the engergy from the ride downback in time so it can make it over the slope?

[Creative360Studios]

@ZaneIsRandom this has happened b4 with chemistry, don't forget those exceptions!

[arnieisbeast]

0:41 BEAST MODE!!!

[nico3dog]

Man this is crazy! It's so complicated. All my life of learning physics and atoms I've learned that electrons DO NOT go into the nucleus but now I'm learning they do... Thanks for making this. I'm now ready to say screw atoms lets learn quantum physics

[AXiSxToXiC]

N O N O N O N O o n O N O N O no O N NO NO NO NO NO NO N NO NNOOOOOOO! ELECTRONS DONT GO IN ATOMS I DONT UNDERSTAND!!!!!!

[PDopey]

But, but, but, how does the electron hide out inside the nucleous with out interacting with all those dirty protons?

[Forkontheleft10]

So basically quantum physics breaks the laws of physics?

[chemicallingo]

@Forkontheleft10 ...no. Quantum physics are the laws of physics. They do 'break' classical conceptions of the laws of physics

[RobloxRainStudios]

Uhhh Warp?

[snipeLAX]

Mind=blown!!!!

[tamtam299]

@BitterBurst I wish you could spell. :\

[Snootwaller]

I have only one question: what's quantum tunneling?

[SonnOfNeil]

particle in the middle of the month..



[fliminthebox]

cool beans

[vincentleest]

just hand an exam about this.. lol... lots of fun..

[BlackPsuedicide]

transcribe audio: 0:09 "than i from you've got to breast conservation of energy penises and they..."

[kiekenz]

So when i fall from my balcony, while there is a wall, higher than my balcony, on the opposite side of my balcony, there is a chance of me bouncing over it cuz there us a very deep hole on the other side of the bolcany?

[shin1300]

so when i drop my pen in class there is a chance that it ended up in an alternate dimension? I KNEW IT!!

[qtxyz]

@shin1300 NO, it's just closer to the floor then you thought.

[Commenter408]

energy penises? at 00:13? XD

[maxim2themax]

I don't see how that's possible, but whatever.

[NinjapiratePC]

@maxim2themax Nothing is impossible, just a bit unlikely.

[mechwarreir2]

Is this the heisenberg uncertainty principle?

[whiteboie79]

Why was I not subscribed to you?

[koobz21]

still haven't told us anything as to the "why" of the situation...

[scientistk]

portal gun!

[waffleman725]

even though i understood almost none of it i fell slightly smarter;)

[wonderpaint]

one part of me is "physics coolio"

but the other part is "OMG PRETTY PICTURES!!!!

[StaticLucky]

@sangfroijdjen i was taught,in chemistry, that sometimes electrons are in the nucleus. i don't recall why now, though.

[imloggedout]

So what your saying that a ball can't go any higher than the height from which you dropped it because of conservation of energy penises?" Hmmm... i think you need to check where you got your facts from.

[ThoseWhoOppose]

You know i used to think that arrow joke was funny, but then i took an arrow to the knee.

[solow2343]

omg...i'm in fourth grade and i actully get it!It cant be!Im a taco monster!

[limelight55]

i used to like watching videos but then i took an arrow to the knee

This is what I do when I SHOULD be studying for exams, but I don't feel like it, but I still feel like a I have.

[sangfroidjen]

Electrons within nucleus of an atom.....quantum physics contradict a lot of what we were taught.

[MrPizzapoika]

Well... That's actually extremely simple isn't it? Movement of particles isn't determined by gravity?

Just saying that because most of these make my head hurt.

[Toffeeproductions3]

than i from what you've got to breast conservation of energy penises and they

[midnightwallflower]

This sure does make shitting more complex and frustrating.

[DrVagary]

I actually knew about this before I watched the video.... BEST. DAY. EVAR.
