Ever heard of Quantum Operators and Commutators? (Explained for Beginners)!

[@ParthGChannel]

Hi friends! Part 2 of this series is out now! Check it out on my channel, or down below!

[@ParthGChannel]

Hi friends, check it out here: kzbin.info/www/bejne/mnnTpYR5jcmEn9E

[@pritivarshney2128]

Sure. Great explanation! I ALWAYS WANTED TO KNOW THE MEANING OF EHRENFEST'S THEOREM. Thanks!

[@enterprisesoftwarearchitect]

Awesome work! Subscribed now!

[@voidisyinyangvoidisyinyang885]

check out quantum physics Professor Basil J. Hiley on how the operators are fundamental instead of just "acting on" the wave function. Noncommutativity is the key to nonlocality. Maybe if Ehrenfest had known this he wouldn't have committed suicide.

[@amjadalhindi7350]

Oh my god!!!! 1- your voice is calm and relaxing 2- you explain things smoothly 3- i JUST realized the physical meaning of commutation and the operator order things from YOU and i screamed! Mind blow!! 4- you sum up the video at the end, this shows you really *care* that viewers really *understand*! I subscribed at one point when i was watching the video, then THREE times during it i thought of subscribing before realizing that i already did. Sir, thank you!

[@fikirbirru2586]

I have a hard time understanding this operators, but when you explain it, I now have a better understanding of it.

[@DM-mx6pd]

I used laugh being indian when foreign people used say that everything becomes easy when an indian teaches you. After watching your videos I believe they were right.

A hundred "Likes". You are the first I've seen to give an intuitive conceptual explanation of commutators before giving the definition. Perfect!

[@exponentmantissa5598]

These videos are really well done. I am a retired engineer that always loved physics so I have spent a lot of time reading and studying since I wrapped up work.

[@lewisleslie2821]

Great video, my QM lecturer sucked at explaining commutators so this was very much appreciated!

I can totally relate... Either that or I just wasn't listening 😅

Hi, I just wanted to say thank you so much! I am an undergraduate physics major and have my quantum physics exam in two weeks. This helped me so much! I was really confused after the lecture, but now I think I start to understand the topic. I wish you were my profesor...

[@itfanizam]

I am in love with his way of teaching.he makes everything so easy to understand.. amazing

I’m an undergraduate student and currently studying in this topic. This video is very helpful. Thanks a million. :)

Wish I knew about your channel earlier... Love how you explain QM. I'm officially a fan.

[@corrzyLAD]

Thanks Parth these videos doing bits for my revision - year 2 uni physics

[@georgearrington5766]

Very nice presentation on commutators, Parth. You explained the value of knowing how this applies in QM problems.

[@I_Am_AI_007]

AB is not always equal to BA. That's why commutators are important in quantum mechanics. My teacher never told me this even after I requested.

[@TheAutistaBarista]

I don't know if you will see this but I was struggling recently in my senior year with all the notation and was worried about whether I'd make it in this class. Your succinct explanations have opened my eyes and made me realize things in a way where I no longer see babble but see actual logic behind what I am reading. Thanks so much, you're amazing!

[@schmetterling4477]

If you are struggling with notation, then you shouldn't be in the field. This is absolutely trivial shit, kid. ;-)

[@silverspin]

@@schmetterling4477 why do u say that TvT

[@schmetterling4477]

@@silverspin Why do I say what? That one has to know what a scalar product is and how linear operators work? Because that's the math that's in play here. If you want to read Homer in its original language then you better learn classic Greek. ;-)

[@BasedMathLover]

Thank you for this ! I’m a middle schooler with a passion for math and this was explained so well I can even understand it

[@jaybhambure5969]

Around 5:30-5:44, there’s an error. Probability is proportional to | psi |^2 not (psi)^2. This is extremely crucial as wavefunction is in general complex and (psi)^2 yields a complex number and we cannot “measure” complex numbers. We need the solution in terms of real numbers hence the modulus is important.

[@anant_singh]

yeah that's right. But we mainly focus on the commutators in the video, so we can ignore this little thing. But yes, thanks for pointing out the error.

[@FabiFisica]

I'm amazed at this subject and the facility with which you explain it! I would also like you to give a physical interpretation of what it means for operators to commute. Keep it up and greetings from Colombia!

[@krishnaraoragavendran7592]

Operators +×÷- are high school mathematics. Operators in quantum mechanics are extensions of the above operators (comprehensible to every day life), which are not comprehensible to every day life but needed to do calculations in a different kind of mechanics known as quantum mechanics

[@ankitholagundi1024]

Parth you are really making quantum mechanics interesting.... waiting for your next video brother

Very interesting, informative and worthwhile video. To say this video is excellent is an understatement; this video, and others by Parth are absolutely superb and a must see for anyone interested in the sciences.

[@quitecomplex6441]

This video is a pretty good video, and in general this channel provides something I think is missing from a lot of book, an explanation of what the physics is. I’ve read about commutators, but never understood why they were important until now.

[@mnada72]

You are doing a great job bringing these advanced notations to common people interested to explore the front shores of science. 👍

[@saswataroy5849]

It was a great video.. will you plaease make one explaining CSCO.. thnak you

[@petrmasek4506]

I think, if we can use classical physics. We can see that Ek = 1/2mv^2. And momentum is p = m*v. If we multiply kinetic energy by m/m (which is basically as same as multiplying by one), we get Ek = (m^2*v^2)/(2*m). And we can see that we can write this as Ek = (p^2)/2m. :)) Nice video Parth

[@themathhub5472]

u r COOOOOOOOL, brother. im just a highschool student who is generally not much good at math but i was still able to grasp the things that u mentioned.

[@vatsan2483]

Hey Parth.. nice content of scientific context in a way simple terms... Two things peculiar about this: 1) why strangely is the commuter result of position and momentum have a complex value to it when what u measure are basically two real quantities 2) in regards to consious argument it's more like the single electron slit experiment where diffraction pattern isn't observed just because some weird way the electron knows we are measuring it.. but in double slit experiment even when we have a observer(detector) in one slit even though the likely is 50-50 it's more like the electron passes through other slit.. so the whole picture of electron knowing that we are measuring it influences the particle nature

Like you I have despaired of finding a good hairdresser. Unlike you, I don't understand Quantum Mechanics. I am one of those sad cases to whom maths is a foreign language and one which no matter how hard I try, I cannot grasp. That makes understanding anything to do with physics difficult except at a language level. I get some of the concepts but the moment they verge into maths.......Nah. So given that, how nice was it to come across your channel last night? Very nice. I still don't understand the maths, but thanks to you I am becoming more familiar with the terminology and seeing how those terms interact, so thank you for that. Point two: Your language. How restful, how pleasant, how lovely to hear someone speaking English so precisely and eloquently. Not an UM to be heard. Thank your mum and dad for me for insisting that you speak well LOL.

Just an observation, the operator applied to the wave function looks similar to an argument applied to a function (mathematical or as in a program), from which we get a value.
