[@jaybhambure5969]

I am not trying to be pedantic here, but Matrices are a "Representation" of a quantum state or operators. Furthermore, matrices can ONLY be used if we are dealing with a finite number of states e.g. the spin of the electron. If we have a system with Infinite states e.g. hydrogen atom or scattering of particle or even operators like the position operator, we cannot use the matrix representation, in such cases what we need is an abstract representation, which is the Bra-Ket notation. To push this to an extreme limit, no one really knows the dimensionality of the Hilbert space. We ASSUME it to be infinite (postulate of QM)

Completely agree. So glad I found this channel

[@perpetual_bias]

This has been _extremely_ eye-opening. Thank you

[@clint330]

seriously loved this! i now get the wave equation notation like never before!! I'm an electrical engineer by degree and I work for NASA JPL and I've studied quantum mechanics a bit for particle accelerator and plasma physics work that I do but the math for QM hadn't quite clicked for me until you just explained it in the 2d space similar to the unit circle for complex math! GREAT video! and i hadn't known about the ket and bra and bra-ket lol thanks! i really like all of your videos! please keep it up!

[@ianbolton9601]

Excellent... I studied this 30 years ago as an undergrad and it brings it all back. Very clear and I agreed with the another persons comment that more of this stuff needs to be explained and taught to 16 to 18 year olds; this video helps make it accessible.

[@stevemetcalf2482]

Just the kind of level I am looking for. I'm a retired 69 year old just discovering quantum theory and love everyone of your videos. The comments section is also very entertaining, and at times controversial. But what would physics be without some challenges? Keep up the good work sir, you are an inspiration.

[@cybrainx72]

You are one of those no-nonsense youtuber :) Thanks for making this.

[@xfoxawy]

u just explain it as simple as possible which is amazing keep it up my man

[@HaiderKhan-nc9gf]

My dear Parth you are a blessing. Because you explain every little thing from the very basics. Not many are doing that with such clarity and eloquence as you do. Thanks

[@littlemermaid3058]

Hey Parth! I can’t thank you enough for this... For once quantum physics started making sense to me .. I used to love physics until it all seemed getting so abstract and complicated , I lost it completely .. I have been a housewife for past 6 years and you make me think of getting back to studying physics. I watch your physics videos in my free time.. I have a request for you.. Is it possible to make a video on evolution of physics ? How different fields of physics came into being?

[@bineshpv8784]

I am 38 now .... I still want to learn QM in depth. I realise that you could help me in suggesting the correct references in addition to watching your videos... you explain everything very nicely..excellent job...keep it up.

[@prgnsean]

TERRIFIC video. Ive heard guys like Sean Carrol talking about "the dimensionality of Hilbert space, and for the wave function of the universe, is it infinite?" and never really got what that meant. Now i get it! Its a measure of all the possible states of a superposition. Very cool!

[@culturedgator]

Love your content

[@RyanK-100]

Wow. This guy explains the basics in a way that NO ONE ELSE does. I used bra-ket notation for a year in grad school without knowing, really, what the hell I was doing. I just did it by following patterns which allowed me to pass tests. No book, professor, or classmate could explain it - they just used the very concepts in question in their explanations. This Parth guy boils it down to the fundamentals - a natural teacher and almost a mind reader.

[@asthaghosh9108]

[@xouzaing7868]

Please do more of these. They are extremely helpful for someone as myself who hasn't studied physics at university level (yet). I would personally love to see some more/a continuation on Schrödinger's equation, but of course also just whatever you feel motivated to make.

[@neilmccarthy1036]

Absolutely amazing explanations!!! Just fabulous!

[@jaybhambure5969]

@4:29 Hey Parth your videos are great, and I really enjoy watching them. Just a small thing -- I psi > is not a wavefunction. Its a ket. Once you take an inner product of I psi > with either position < x I or momentum < p I basis it becomes a wavefunction. Further you cannot do these inner products with spin because it's an internal degree of freedom and has nothing to do with space or momentum, hence we only have the abstract notation of Kets no wavefunctions for spins.

[@jishnun4537]

[@zhabony1]

Man, Thank you very much! I was not bad at maths at all, but spent weeks trying to understand how spins are described with vectors. Even in basic quantum computing intros either book or youtube videos they start with electron beams bent toward North and South magnet pole, spin can be up and down, and suddenly they show vectors up and right(!?) (what the hell?). North-south, up-right are (0,1)and(0,-1) why they use (1,0)(0,1) ?? Now it is much clearer ( at least to continue reading about :-) ). Thank you for your time putting together this video!
