Quantum 101 Episode 9: Quantum Tunneling Explained
Вставка

- This video discusses the concept of quantum tunneling, and how this phenomenon only works because particles can act like waves.
The fastest baseball pitch ever thrown reached over 170 kilometers an hour. That's impressive. But even that record breaking fastball would never be able to pass through a solid brick wall.
It's just not possible. That is, unless we're playing quantum baseball.
A thrown baseball might have enough energy to rip through a piece of paper, but even the fastest pitch would just bounce off a brick wall.
Yet sometimes quantum particles are caught passing through barriers they don't seem to have enough energy to break through.
Logically, they should just bounce off. And yet there they are, sitting quite happily on the other side. How can that be possible?

How many Non-Physics majors had their minds blown with this phenomena?

@@anolakesyou sound like someone I’d love to be friends with lol
You must surely be the life of the quantum particle pickle party.. Spooky actions, at a distance.. 😬🤔
Quantum mechanics is like magic
An excellent intro- but it raises lots of questions for me to explore further!
welcome to physics.
We don't actually see an atom with a tunneling microscope. We feel the atom. And record that touching as a coded signal. Then the data gleaned from that procedure is reprocessed/transformed into pictures. We see a graphical interpretation of data. Nothing more.
Sounds plausible.
the music could be a bit louder, i still heard some talking here and there
Too cool. Thank you, Katie.
Great Video! Thank you!
The video ended before quantum tunneling was explained. It was described, but NOT explained.
Then you'll never get it...expand your mind...try researching propagation...it may help...blessings
@@ogi197 I'm just making a point. I don't want to give away the details. I prefer that people discover things by themselves. Granted though, I did many years ago show how a high school dropout who knows nothing about physics, can independently discover the Special Relativity(SR) phenomena, and at the same time independently derive the SR math equations. The key to the success, is the knowing nothing about physics, thus knowing nothing about the incomplete and thus flawed, physics of today.
waves acting like particles, i.e., the water droplets, "jump" from the electron side to the reading side completing the circuit. they dont jump, the energy probably "builds up" and then the electron suddenly turns into a drop of water on the other side.
so energy coalesces on the other side enough to generate a discrete unit of electron?
can someone please show the Feynman diagrams? I'm pretty sure there is an intuitive explanation for this.
Im a chem major and i was searching for quantum tunnelling in SHO, nonetheless this is a good base level intro
Thank You.
An explanation was provided for space travel using Meta materials. As space is saturated with energy on a quantum level and given that all locations in space and time are mathematically mappable, space travel is possible by using an Alcubierre warp drive. The propulsion system operates on the principle of quantum tunnelling, hence a craft equipped with an Alcubierre drive will not travel through space; instead, it will instantaneously relocate itself (i.e., Jumping from one location to another). Relocation is done by the drive tuning to the unique frequency of a particular position in space-time.
Confused to as why they explain quantum tunneling like this nowadays because this isn't what the experiments have shown it as, in the case of the electron quantum tunneling it was more of a specific exchange of energy as it was absorbed it spit an electron out the other side at the same time to maintain the same amount of energy in the atom. And that's why they used to say it would allow particles to move faster than light, and with this new idea that's not the case and doesn't add up to what's actually happening.
Do Josephson Junctions rely on this?
In my way driving the center zero inside the gapping zone is a speed of light .
Up is driving , center is driving and the bottom is driving .
Antigravity way . No weight is present .
Thank u❤
This is how Flash phase through solid objects
my man did not deserve those camera angles
Convinced me... physicists really have no clue.
What’s unique about this video is that they are not trying to obfuscated that fact.
More like this please. (What we don’t know)
Physicists know a LOT of things, but there's even more things they don't know. So they know about these things by knowing the things around them. It's super cool how they're able to get around them
@@sidneyrobinson18spoken like a very young man.
Physics: yeh that’s cool, but today’s physicists... some... maybe... can’t think on any under seventy years old off hand. But the vast majority? Cool? Naaaw!

Newtons cradle?
Bear with me a moment. Concerning the Mandela Effect, it seems that dimensions and/or universes...coexisting within the same space according to Thoth in Emerald Tablet #9, are separated by a thin electromagnetic veil. Now if enough electromagnetic energy could be generated...like 13.6 TeV maybe, could these "veils" be pierced? I have a gif showing how if these universes bump up against each other via a method like this, they don't merge, but basically small particles could be transferred back and forth and small changes could occur in one or both. Just theoretical, but something to study and consider. I've been watching CERN for over a decade and I fully believe this to be a valid theory.✌️🕊🌿🔱♎️💫♒️🌠
I'm intrigued...what brought me here ???
One day before exam😢😂
In a most rudimentary manner, CIG Theory may explain Quantum Tunneling. Try CIG Theory today.
Think im in love
Imagine if somebody could use this to move through space
dude what is this camera angle
Wow, quantum tunneling, neat. Perhaps, it could be key to resolving for stalemates in conflict. Every so often, humanities perspective jumps into a new perspective. How? Humanity tries to create standards to best organize and highlight potential breakthroughs, but it almost never works. Real breakthroughs come through a series of events, perhaps unrelated, perhaps in conflict at first, but ultimately greater than the sum of its parts. Phew, now I can relax, the decay of the vacuum of space will not likely decay on me, just taking it one day at a time.
She's wearing that Greek Antiquity ahh fit
1...hello humans
2...so ur living in my constructed and created universe
3...those humans ,who are trying to understand the construction and execution of universe ,so you want my chair..?
4...why u want to understand the working procedure of universe...?
5...bcoz u want cheatcode to activate the free will facility
6...it is impossible to crack the ,my created universe in which ur present now
7...i am just making you walk from 1 stop to another stops ,and this stops are endless , so keep walking
++++++++++++
So I can move through the wall like the x-men?
Well them, they did have enough energy ipso facto. It’s Heisenberg’s indeterminacy principle not the uncertainty (sic) principle! Learn some QM!
my mind is totally blown
How is it possible that One Pair of Entangled Particles communicate lifht years away? Is there a medium inbetween?
I would say something about the line of intermission although I'm curious if the channel producer or crew will answer you better. Also if they give you a diagram it's interesting to see what's not considered a straight line to be the quicker route. Then again they could refer you onto one be there hormer videos.
@cyrus05w it seems like Tesla said frequency on the quantum level gives different outcomes, maybe some Quantum Zero Point Energy Void Battery Module will be buillt some day 😉
Simple answer: They can't do that, medium or not. Correlation is not communication.
@@cloudpoint0 Wouldn't using the flicker Pattern, As zero's and one's. Since the correlating nude is at a certain position within 4 other brackets. Wouldn't the corresponding note that you maintained show the exact opposite position within the same factor indicating 0 or 1? The reference material I made note of in the original comment I'm hoping the channel producer provides it better explains it although if I remember correctly this is how computers also work originally. I also understand that the flicker pattern is only resolved after you look at it that's a whole other box of worms.
@@cyrus05w
No amount of gibberish changes the correctness of my answer.
Funny to think that the sun is mostly not shining
This would be better titled, "Quantum Tunneling Described," as it doesn't explain it.
Yes it does...
I for one welcome our true vaccum overlord.
Very difficult to understand this quantum tunneling.
i can safely tell a physicist shes WRONG so are all these other physicist when these partilces tunnel like a black hole tunneling through the fabric of spce there moving faster than the speed of light liquifying an "AREA" with the rite sound wave frequency if thats not the case then there moving so fast the particle instantly splits into a serious of itself in even smaller matter partilcles untill it comes to then it puts itself back together instantly the matter in tunnels through cant even detect its presence thats how fast its moving but im going with my first guess after seeing a glass window and metel door being liquifid by a frequency!
take more than 5:13 minutes please

Worthless background music makes this hard to pay attention, even harder at 2x speed as I want to.
she actually said kilometer not mile? i guess im gonna cry::))))))
She's in the Perimeter Institute, in Ontario Canada, a metric country, like 95% of the rest of them 😛
Any one else here just a bored high schooler?
Do not understand this. Complex
I dont worry that the vaccum is gonna decay on me because the universe is 14 billion years old hast happened yet so I dont think its gonna happen anytime soon......,ha ha :::sweating ::: ha:::::nervous laughing::::😅
