Quantum Tunneling Explained

[@GenericUser860]

Thanks for making this video! I was watching Kurzgesagt and the Minute Physics link he left to "explain" quantum tunneling was lacking. I searched what quantum tunneling is, and here you are!

[@qmgthequantummechanicsguy5371]

Here is an actual recent experiment: kzbin.info/www/bejne/rWHJpqugndp3b8k

[@sharonzhang7621]

this video changed my life, quantum physics has entered my life now

[@thankfuljosh]

You are a truly gifted teacher. Very well done.

[@lauren5724]

I love your video! As a layman in the field of theoretical physics, I don't understand many videos out there. But your explanation was really clear. Great video!

[@euphoric1183]

who is here from minute physics?

[@ericrbk]

Akın Yaman Altın Did you also wanted to know more about q. tuneling?

[@zakiahmed6655]

well i did

[@secretninja396]

Superb video- you should really enter this into a competition :)

[@vinayannam5589]

The toppic made a tunnel to my mind. Great work

[@JustwaitNwatch-w]

Very nice information thankss I've always liked such concepts

[@jacesaces15]

This stuff is way beyond me, but its so darn intriguing. i actually understood quite a bit and appreciate that.

[@Cloppie]

Amazing video. It's a shame most videos aren't as elegantly explained whilst being just as informative as this one is.

[@jhunter7851]

Your very smart bro and you helped me alot, you deserve more publicity so you can help even more confused people like me!=D

[@qmgthequantummechanicsguy5371]

Yes, it is a wonderful video and he deserves credit. Here is a video with a recent experiment on quantum tunneling kzbin.info/www/bejne/rWHJpqugndp3b8k

[@vijgenboom2843]

Very well explained! Thank you.

[@pavelcacik1670]

Probably the best video on quantum tunnelling I could find online, thanks man :)

[@marcuswong335]

You should make more videos!!!! Very nicely explained and I can understand most of it.

[@vamosabv]

A really nice video. Thanks Jay!

[@BaronVonCount]

Amazing video dude, best explanation ive seen so far

[@g.sudharsangovindaraj9634]

I got it now. Clean and crisp. Thanks mate!💓

[@NandishPatelV]

Finally! I understood the concept and a bit of the maths ;) you introduced the maths at the right time and right level (I’m no physicist) Thnx :)

[@738shani]

THE best explanation

[@miguelsantos2572]

This is a great video!

[@qmgthequantummechanicsguy5371]

For a recent experiment on quantum tunneling, check out this video: kzbin.info/www/bejne/rWHJpqugndp3b8k

[@bidishabose9282]

Really great video... My concept is cleared now. Thank you...

[@igotsth]

I actually think there is higher chance that the cat would be outside..

[@kelcamer]

That's what I was thinking LOL 🤣

[@kisshorekampara7541]

Very good presentation

[@manishsaraf609]

You said it wont allow us to walk through walls, but there is a small nearly 0 chance that it would right (looking at numbers)?

[@derpeth2101]

Every single atom in your body would need to do it at the exact same time.

[@manishsaraf609]

derp1337 ye so it's possible but will never happen

[@mh5s45ra9r8g]

that is exactly the same attitude albert einstein's haters had. Did cave men think cell phones were possible? The answer is No. Just because you don't understand, doesn't mean anything. Everything is an lot bigger then you.

[@zorbajwhk]

Great video!! keep it up!

[@fitnesspoint2006]

As per the math for a billiard ball to tunnel it would move 100th the width of proton in 100 billion years. So it will never happen, has nothing to do with "attitude". Also Einstein did not buy into quantum mechanics.

[@Prashantsingh896]

Nice explanation.

[@aizat27]

This is a great video. Good explanation with some math. Minute Physics quality, bro. Well done.

[@slingshotninja6970]

You have earn yourself a subcriber!!!

[@stxnw]

Nobody explains why the particle tunnels out but you answered my question. Thanks.

[@GenericUser860]

There really is no answer. It just kind of... happens. We have no idea why it does this. It just does.

[@stxnw]

Maverick Jackson Did you even watch the video? Lmao. The probability shadow and the formula was all I needed to know that it is possible to tunnel.

[@sooryas9301]

Thanks for giving example...

[@Mastadex]

Plz make more videos like this!!

[@aleccoles5557]

Excellently explained, thank you!

[@bullseye99o]

This helped me a lot. Thanks for making such great video.

[@akeel77]

Really good explanation!

[@kavitaarya2971]

Thanks for explaining so well

[@CrisMadla]

Holy CRAP JAY THIS IS AWESOME

[@ag_008]

What happens to the momentum and energy of a particle after passing through the barrier?

[@tomyoke1678]

Momentum and energy are both conserved

[@kinsernng8258]

AWESOME VIDEO!!! The maths sorta explained!!! COOL!!! thanks alot!!!

[@ekteshafatdaily]

This video was helpful! Thanks!

[@jaunicorn]

this video is just ok. my life is lost after watching this video. I doubt quantum physics can save me

[@gregflatt7043]

your a great youtuber

[@aniruddhavichare5425]

brother.. u impressed me.. u explain well

[@regularguy12345]

Awesome job man!

[@tscoffey1]

"After the last one DIED"? So that has been determined now?

[@vidyanandwagh6277]

Thanks, that was really helpful.

[@guillermopoli8349]

Very good explanation! :D

[@KodamatiUdayaPrabhuKiran]

I just love this video....

[@jeffmoney5464]

You say that the probability of finding the molecule inside the barrier drops quickly and the probability is much lower on the other side. So is the probability higher that the molecule would be inside vs the other side?

[@adamrspears1981]

Great video! Thanx for uploading it. I am not disagreeing with you. I know that everything you explained in this video is true. So please do not misunderstand me. Call me crazy, if you like. (I don't blame you or take offense if you call me crazy.) I had a dream. In my dream I was in a society that I am guessing was this society, but maybe it wasn't in the too far future. I say that because for the most part the society I saw in my dream looked like the current 21st century society of the modernized world, like America. There was 1 obvious difference between our current society & the 1 in my dream: People were entering & exiting their houses & buildings by passing through (what were usually) solid walls. All of the houses & most of the buildings that I saw had holographic images of windows, doors, garage doors, & entrances & exits. There were no (as I call them) 'Classical Doors & Windows'. No doors, windows, entrances & exits with moving parts. No elevator or revolving doors. Banks didn't have the 'classical' door on its vault, that they have today. The hologram was for decoration & to direct people to the area of the wall where they may be allowed to enter & once inside, can always exit. This was all explained to me by someone, who I did not recognize, in my dream. The key was that you could only enter a house or building if you had clearance. Weapons, explosives, guns & ammo never had clearance to pass through the entrances of public buildings. So school shootings, public shootings in general & terrorism was almost completely a thing of the past. Windows worked the same way. They were signified both from the inside & outside of the house or building by a holographic image. You typically could not see what the actual inside of the house or building looked like by staring at the holographic window. Because its really just a (normally) solid wall. From the inside of a house or building, you may be able to look at the holographic image of the window & see outside. But you first have to choose to allow visible light clearance to pass through that area of the wall, where the holographic image of the window is located. & even though the window that you see is just a holographic image, the light passing through it from outside is the actual light from outside. Now if you want to 'pull the blinds' or 'pull the curtains' over that holographic image of a window, then you just simple deny visible light clearance to pass through the wall, there. The interesting thing about that is, the (for lack of better words) 'network' that orchastrates the digital doors & windows of the house & buildings was programmed to change the holographic image of the window to a new image of the window with its blinds pulled/shut or its curtains/drapes pulled. -Again the holographic image of the window automatically changed like this if the user denied visible light access to pass through the wall area withing the borders of the holographic window. & the inverse is true, too. When the user decided to grant visible light clearance, the holographic image of the window reverted back to the window with its curtains or blinds drawn. Like windows, holographic images of bathroom doors in houses would change to appearring as shut, or as open; depending on its occupant's request to show it to others elsewhere in the house as 'open' or as a 'closed' door. -This only pertains to the holographic image of the bathroom door. The wall space within the borders of the holographic bathroom door image is permeable to the occupants in the home when no one is in the bathroom. But at the user's request, the wall space can revert to its 'classical' state & become solid. -This is essentially 'closing & locking' the bathroom door. Another interesting thing shown to me, in my dream, was a fool-proof system built into any internal door in a house or building. I'll use the bathroom door in a home as an example. Its important to know that for safety reasons one can always exit any door of a house or building be it public or private. When the occupant using the bathroom has 'closed & locked' the door, there is the possibility of them forgetting to 'unlock & open' the door before exiting the bathroom. This scenario is similar to us locking our keys in our car. So the digital doors' operating network installed in the home has a fool-proof system designed into it. The bathroom, bedroom, closet, attic, & basement doors all have light curtains or optics installed within the walls at the perimeters of where the said holigraphic door image would be. As the user exits the bathroom, the operating network sees that they've exited & automaticall 'opens & unlocks' the door. Public bathrooms work the same way, but only concerning the bathroom's stall-doors. The entrances to the public bathrooms that I saw were just like a lot of public bathroom, today, where there was no door. The entrance was, literally, a rectangular opening in the wall. Garage doors, worked the same way. Anyone who did not have clearance to enter the garage either tried to pass through & walked right in the solid wall, smacking it; or worse, drove their vehicle through the wall, damaging it & the house. I don't know how these Digital Doors, as they called them, works. But in my dream they worked & society was kept safe from the bad guys.

[@lunchmind]

So does this mean thatthe odds of me walking through a brick wall are equivalent to absolute zero? or is there a greater than zero chance however inexpressibly minute that I can do it?

[@Mister1World]

Really nice ending ;)

[@gunfaceUK]

Excellent

[@fisslewine1222]

I get how this explains how wave forms interact and thus it seems plausible particles can pass through push into spaces, but consider radiation and alpha and beta do this all the time.

[@thinnesh9587]

great video bro

[@quahntasy]

It's 2018 if you guys wanna know about it more have a look at one of my video on this.

[@predicate]

shouldn't the square of the wave function outside of the wall still be a (vertically shifted) sine wave and not constant?

[@theskepticsniper0012]

an awesome vid

[@RionellKoay]

nice one!

[@ekteshafatdaily]

how does heat cancel out or reduce repulsion?

[@crazieeez]

Can you calculate the probability going through a 5 feet thick wall of a person weighing 80kg? How many times will a person need to hit the wall before he can go over on the other side ?

[@idiotflower]

Just a layman's question: can this be really called "travelling"? The way you describe it seems to be more kind of a "destruction" and "reconstruction" and even this does not come close to the appearance it made to me. Is there a "before" and "after" at all? And: is it the same electron? The electron in front of and behind the barrier, that is... isn`t it more information collapsing into an electron? I even doubt that the information made "its way" through the barrier. Maybe the "new" electron is just another representation of an approximation to something else we describe as an electron. Are we sure that electron deserves this identifier (same electron "Bob" with just a new position, for example)? Sorry, if I used terms that don't apply to physics, but I'm a layman.

[@splicerdicer8800]

So although the probability is basically zero, there is technically an extremely small probability that you could quantum tunnel to the other side of a wall? Given enough time of course.

[@omsingharjit]

[@gunjchowwiwat8357]

What is the wall made of? I dont under stand why physicist think eletron cant pass through.

[@combomaster99]

Good vid.

[@makkah1234]

That was just a philosophy despite of the cat itself! We already know that depending on the nature of the particle ( The mass of the object ), the particle would be able to move across a physical massive barrier if it had the wave properties quantumly under some circumstances ( so small object " A particle " with the appropriate energy ); such that: in the newtonian's point of view, the particle ( An object with a very small mass ) sees the barrier as a space containing some other massless particles each group of which orbits arbitrarily around a specific nucleus of a matter independently whether those orbiting particles follow an exact circular, elliptical, or a path represented by a probability wave function " phi = e^(i(kx-wt)) = cos (kx-wt) + i sin (kx-wt) " along either a spherical or an ellipsoidal surface. If any of those particles are encountered by any of the other massless particles having either the required mass or speed ( momentum ), it would be bounced off its direction due to the collision ( probability ). Whether the particle going off the last point of the barrier is the original particle or "The massless particle being bounced off", observe that with a higher driving energy, any particle arbitrarily with an arbitrate energy besides the direction may be exist on the other side.

[@rider2731]

In my humble (and probably wrong) opinion, humans cannot walk through walls because humans are so much bigger than the empty spaces in the atoms that make up the walls. But electrons can go through walls because the empty spaces between the electrons and the nucleous of the atoms that make up the bricks (assuming they are brick walls) are big enough for electrons to go thru. Much much bigger. Also, using humans as the example is confusing because quantum physics are valid on masses that are extremely small (sub-atomic level). Does anyone agree?

[@SpectrumSplit]

Nice video! :)

[@SpectrumSplit]

***** Oh, welcome! :)

[@fitnesspoint2006]

there is a huge problem with the diagram - that there is no true wall, if we are at the level of a wave or photon then there is no wall but giant holes or other atoms and since most of space with in atoms and between atoms is empty space then there is no wall but lots of empty space and I can see how tunneling can take place between these giant gaps

[@Michelle-jf8fz]

If you can't walk through walls, why is your video titled "How to walk through walls"

[@maxongomeka4250]

how does quantum write data in a solid state device????

[@nemanjabasaric4042]

Great video :)Three people who disliked were too stupid to follow

[@sombasevarovasa8834]

Thanks

[@Ethan-qe7cr]

Ummmm, it is possible for a human to walk through the barrier! The possibility is not 0!!!! But very close to 0, so it's still possible, given that you have enough time and energy to ser come the task.

[@zbiv]

One of the best explanations online. Only problem- taking equation as a way to prove doesnt really explain how it happens physically... so, the equation proves that it can be left or right of the barrier, but what is happening at the electron's physical level that makes it appear on the other side?

[@sirbruce1970]

+zbiv To understand what's happening physically, one needs to understand why there's a wavefunction at all. And the reason there is a wavefunction is that the energy of a particle is not always constant; even in a vacuum, a particle can randomly gain energy for a short time from nothing. This allows the particle to have enough energy to move through the barrier.

[@elderacorn1151]

Would this suggest that in an infinite amount of time I would be on the other side of the wall infinite times because while the chance is slim, there is time for that chance to occur

[@yolohero2251]

Not like a proper wall but not sure what the math is if the barrier Is thin enough. If it’s a non zero possibility then I guess you would be on the other side , but I think this is just for quantum particles the math wouldn’t work for something bigger

[@MrOracos]

beat video i ever seen

[@jpsx4ever125]

Nice explanation even I understood that the magic used to go through the wall in the first harry potter movie was manipulating quantum physics and made quantum tunneling more likely to happen ! I guess Im probably wrong anyway nice vid !

[@qmgthequantummechanicsguy5371]

Here is a recent experiment: kzbin.info/www/bejne/rWHJpqugndp3b8k

so it's still possible is what you're saying

Well I guess the Flash has the ability to "tunnel" through the wall by vibrating his whole body hehe

[@amitaimedan]

What do you mean "it just appears on the other side", this is stupid. Maybe you just can't detect it, but it's not "just appears".

[@qmgthequantummechanicsguy5371]

Great point! You can interpret almost all in terms of waves. Here is a recent experiment with almost an interpretation in terms of waves kzbin.info/www/bejne/rWHJpqugndp3b8k

[@mangoboy4reel]

All this to tell me that I can't walk through walls? I know I can do all things! ... because I am not You....nobody can't tell me what I can't do....only I can tell myself I can do...and what I can do...i do because i can do all things...I am that I am...and I am not limited by quantum explanations from people who believe they can't....you believe you can't so much that your probability is ZERO........with that kind of thinking...you all will remain HUMANS for generations to come and never make any spiritual progress....just advancing in technology that's further keeping you in a state of quantum delusion making you think you can just explain things and be right.......no matter how much you explain and sound smart.....y'all don't know anything if you cant do anything without thinking you can explain everything and equates it to ZERO.

[@samiboshgezen382]

Don't buy cats. Adopt them.

[@rochestersquarecome-unityg5414]

Metaphysically Speaking -The human body holds the potential capability to pass through solid objects such as walls, and other phenomenon such as walking on water. This requires purification of the body on a physical level, into a matrix beyond our material understanding, embodying a stable quantum flux ... capable of superposition alignment. We are fore sure attaining new paradigms of capability - once we improve our ability to unlearn what has been our thus far indoctrination.
