- Опубликовано: 24 сен 2017
- This chemistry video tutorial explains the concept of heisenberg's uncertainty principle in a simplified way. His principle applies mostly for small particles and events. As the uncertainty in the position of a particle increases, the uncertainty in momentum decreases. This video contains some math practice problems that illustrate Heisenberg's uncertainty principle.

@@olivialindstrand589 i am a bot, and i just wanna tell you hi.
Me too .all de way from kenya
Hope you’re doing well
Bruah nooooo I still haven't graduated. Good lord help
U are the best... Instead of going to lectures, I just check the course outline... The I search the topic...... And when u teach it doesn't require going back again
Where do I pay my tuition at?
Facts. I would love for him to be my teacher.

Very nice video! Congrats! That’s the simplest explanation to Heisenberg’s uncertainty principle I’ve seen!
Most helpful educational youtube channel. Good job
Another Punjabi in Canada
there are no words to describe how helpful and stickable to memory your simplifying abbilities are !!!
Jesse we need to solve 🎩
Even tough the math gets away from me, it does prove to me the truth of the uncertainty principle. Thank you very much for this video .I'll watch it again.
Layman's terms for looking at the uncertainty principle would be very simple using no mathematical equations....
If I had an object that was moving through space and I wanted to know its exact exact exact exact exact position. I would need to stop the object to obtain this information and it would have no velocity at that point.
Also on the other hand if I really wanted to know the velocity of an object in the study its momentum it would not have an exact exact exact exact position because it would be in motion.
Heisenberg's showed this how it would work out mathematically but for someone that doesn't want to do the math for understand it that's basically sums it up.
This was directed but not solely for Dana Franchitto who posted comment 9 months ago
Fantastic explanation. you saved me 10 minutes to complete watching the video ,some of us just want to understand the principle and not the math ,
@@privateaccount8027 lol.. it was a generalization... you know like "general relativity". 🙂
@@privateaccount8027 uncertainty principle refers that a particle can only exist in one domain. Exact position or velocity domains. It would be like saying I'm standing motionless/still and running down the street at the same time. Now don't forget the perspective of the observer, are we measuring velocity for my perspective which could be flawed. The tangled webs we make...lol
Exactly 😉
Like your videos a lot. Very nice way to get to the point. Excellent JOB.
Professor Organic Chemistry Tutor, thank you for a powerful analysis of Heisenberg Uncertainty Principle as it appears in Physics and AP/General Chemistry. I have seen the Heisenberg Uncertainty Principle in Engineering Physics Three,, however I really did not understand it until I watched this short video. This is an error free video/lecture on RUclips TV with the Organic Chemistry Tutor.
Clearly and briefly! Helps me a lot to understand the principle!👍
such a simplified explanation.Very easy to understand.Thank you so much🙏
This was so simple and so easily digestible. Thank you very much for your hard work.
Thanks so much for taking the time to make these videos.
Thank you so much! Huge help, as always!
Thanks for the vid man, the concept looked really complicated in my textbook
there is so many similar topics in physics and chemistry ! anyway thank you so much sir
thanks a lot.This will help as am preparing for my exam
you are the biggest blessing to mankind my friend God bless you in abundance
your existence is a blessing. thank you so much !!
This is such a great vid!
I’m curious how this is applied to harder problems
Brilliant! Just brilliant!!! 👍👍👍
Sir you are greatness💯
well simplified and explained 👌m thanks a lot!
Thank you so much sir. It helps me a lot. 👍👍🙏🙏.
Great video.
Taught this better than my lecturer. 😊😊
Excellent!
Thanks alot,, your page is helpful. Lots of blessings
Really helps during the lockdown
Thanks so much! Saving me the night before a exam.
Thanks!
Thank you.
Thanks so so so so so MUCH!!!x :)
Thank you so much😊
Heisenberg stated that you cannot know both the position and the momentum (mass times velocity) of an object with an absolute certainty at the same time. Basically, if you are absolutely certain that your velocity is 85 miles per hour, the certainty in your position goes to zero, making you not sure where you’re at
Thank you❤️
Great expl
thank you so much, I love you
I LOVE YOU MAN👊
A good refresher course!
Thank you 😊
You are incredible
Thank u💚
Thank you
Does probability has to do something with this?
From Kenya,and am greatful
You're an incredible professor, really. Congrats for your work!
jesse we need to cook jesse
I think it'd be more simple to memorize it as Walter White's Uncertainty Principle..😁✌🏻
Damn that's wayyy easier than I thought
He’s good at teaching, that’s why.
because you're Heisenberg
Wrong he is enberg
Can you tell us about the formula of wave functions
JESSE. We gotta learn physics jesse.
Yeah mistah white. Yeah PHYSICS
When theorganicchemistrytutor became heisenberg🤠
waltuh
Question: What happens to a particle if you confine it to a very definite position and try to measure it? Does it gain infinite speed?
As Ryan mention uncertainty principle says that it is not possible. Though I do believe if you could contain a particle in a very small space on fraction on the Plank scale it or may be possible for the particle to gain infinite speeds in a very small space. This would be possible due to E=mc2 and may be the cause of a particle being in a superposition... thoughts anyone?
@@pauldevan7245
Why would it gain infinite speed though?
@@pauldevan7245infinite speed is impossible. According to special relativity, all rules of physics must apply for all observers, which includes no velocities Greater than c
In these hard times in Africa and around the world,,you really save lives
sir how to find smallest possible uncertainty in position of an electron moving with velocity of 3x10^7 m/s.
Thanks
Thank you for getting me through my senior year or high school
You’re learning this stuff in high school? 😲
@@soniclevels1514 no, for my English class they let us choose a topic to talk about and I chose quantum physics
I'm studying this at the beginning of my junior year of high school. My teacher is an absolute shit so I have to learn it on you tube
@@soniclevels1514 i did learn about this in High school 😬😬 it was traumatizing 😂
Are we not converting the units of kilograms in the mass of e` to the units of joules in the Plank's Constant? Please I'm kinda confused,
Can you do videos to Explain all researchs
Thx Bruh! From India I'm in 9th & preparing for IJSO
❤🇩🇿🇩🇿❤ I follow you from Algeria
Thank you so much for such an easy and convenient explaination...
Can we have a face reveal video???...pls ...
Much love from africa
My university's chemistry department is absolute garbage...
sahil sultan UH Manoa
yall learn about this in chemistry?? Im here for my physics class lol
@@spicyy812 quantum mechanic is sadly the basis for chemistry😭😭
@@eshaxcx yeah that makes sense, but ive just never heard someone take a chemistry class based on/called "quantum mechanics" xD
@@spicyy812 and you wont find any😹 im just referring to the name of this branch of physics
Sir you did not tell how to increase or decrease the uncertanity by using waves
my textbook has it as h/2pi instead of h/4pi :/
same
h/4pi(or π in greek)= h bar(h/2pi)/2pi=h/4pi
Same
preview pic looks like ps4 cheat sheet
I liked this video even before watching
might as well stop paying tuition and learn everything I need to know for my MCAT on this channel lol
What if Δv = 0?
You then get the strange equation:
Δx >= (h) ÷ (4π • (9,11 • 10^(-31)) • 0)
Δx >= h ÷ 0
Since deviding by 0 is not possible, what should I do. If someone spots a mistake in my calculations, or if Δv = 0 is not possible (I wouldn't know why), please respond.
I think Δv = 0 would not be possible because it mean that the partial is at absolute zero and it's not possible.
delta v = 0 implies that the uncertainty in momentum = 0 because delta p=delta v * m, which means your are 100% sure what the momentum is, which is impossible because of the uncertainty principle. Saying you know the momentum with absolute certainty then implies that the position could be absolutely anywhere in the entire universe, which because of the uncertainty principle we know cant be true.
@@chaoticstorm8145 Thanks
Position uncertainty will be infinite and vice versa is also true
Thanks sir🥲🥲
how to solve when accuracy is given ?
what does the 4 π do in the equation?
It’s a spook
Please solve neet questions
sir why we use greater and equal sign in this equation of heisenberg
There is no negative distance or speed. If a car is at rest the momentum is zero and the same is for it's location. Therefore, the uncertainty is either equal to that value or greater than that value.
why did you had to convert the answer to micro meters?
The way we must convert micro Metres to 10^-6, that of kilograms why can't we convert the kilo to 10^-3 here, just a little bit confused about it
“Yeah, Mr. White! You Really Do Have A Plan! Yeah, Science!”
is it not supposed to be all over 2pi
what is the essence of 4 pi in the equation?
That's what am asking cos am seeing 2pi
But you can calculate the result of a coin toss using angular momentum ignoring air resistance and wind effects can't you?
I finished watching this, now I'm a druglord.
Can someone explain h/4π
Why is h divided by 4pi because some textbook use h divided by 2pi
In the text bok there is n variation of the planck constant, but they are equal
Officer: You were driving 50 mps before I pulled you over.
Me: Have you heard of the uncertainty principle.
what happens if you put a photon that has no mass
photon is said to have zero rest mass but it's always moving so it has momentum
(p) where p = E/c and E=hf
Now say my name
But here in my textbook,the uncertainty principle's formula is given as ∆x.∆p=h/2π not h/4π
It's not h/2π , but it's ℏ/2 .
See it again ☺️
Heisenberg, a great mAth cook.
at this point hes not my tutor, hes my professor
Frankly, we don't even know the mass of an electron. Free electrons are saturated with more stationary photons than the one of stationary electrons. J. J. Thompson is measuring the charge per mass ratio of free electron rather than stationary electrons and needless to say it is definitely not bare electrons. We have no ideas how many stationary photons that are adhered onto the measured free electrons. In addition, different saturation of stationary photons adhere onto a free electron will have different mass content, momentum and magnetic field strength. Therefore this makes it virtually impossible to know the charge per mass ratio of free electrons. Millikan's oil drops experiment can't be replicated even with better apparatus, and we suspected Millikan fabricated his data about the charge of an electron. Frankly, an oil drop no matter how tiny it's is considered to be huge in size that consisted several oil molecular structures where they can adhere with high variations of stationary electrons. Therefore it's naïve to assume there is small, integer number of electrons that adhere to those oil drops. In addition, the charge strength of an electron is just too small that it is considered to be negligible. Therefore it's impossible to measure the charge strength of an electron no matter how sophisticated our apparatus is. Since the charge of an electron can't be measured then we don't really know its momentum. The interesting question is how we measure the electrons velocities? Frankly, we have no idea how to measure their velocities since they are revolving around the nucleus so swiftly. One must be talking if he claimed that he know how to measure the velocities of electrons. Likewise we know stationary electrons are confines within an electron-shell of an atom but we have no idea about its exact whereabouts within the electron-shell simply because they are moving very fast. Heisenberg's uncertainty principles turned out to be a bluff. Knowing the position of the electrons that we will not know their momentum? In reality, we don't even know its location at the same time we also don't know its momentum! If you are interested in real discoveries, I would recommend you to read my book, The Unification Theory - Volume One and you will be amazed with lots of new, interesting discoveries. In God I trust.
Can I have your contact?on WhatsApp
you explain very well but can you please make your voice audible
sad thing is, i have my mid terms tomorrow and my school (actually, the whole country) _doesn't allow calculators_
lol i might fail just cuz of the calculations T^T
but at least i understand the concepts ;)
India? 👀
WHERE IS THE MEATH
The formula says x and p can't be small at the same time.
