L1.1 General problem. Non-degenerate perturbation theory 

FINALLY, This has actually made my day. I watched 8.04, 8.05 and can complete it with 8.06. I now have plans for the weekend! Thank you Dr. Zweibach and thank you MIT!

i have been waiting for this for years

I am an MS Physics student and I now know what I will be watching this summer. Thank you for this lecture, the professor is a wonderful lecturer.

Prof. Zweibach is the best prof I've never had

I was one minute into the video and I immediately knew that this guy knows what he is talking about and is a good lecturer. After having seen more of him, I can say I wasn*t wrong and thanks for sharing these nice lectures!

Gracias por representarnos tan bien profesor! Saludos de un peruano terminando su maestría en Alemania

what an excellent professor!! Greatness..even the introduction, the discussion, the ending ..superb!...so satisfactory

This course is an incredible gift. Thank you, MIT. You are truly generous. Thank you, Barton Zwiebach. You are a master teacher, brilliant, and rare indeed. Thank you, RU-vid/Google. These are not only not evil, but actually, positively good.

evey secound of this vidio is more valuable than gold to me .thank you mit

brilliant brilliant lecture. Thanks Dr. Zwiebach and MIT for making this available for free!

I learned so much from Dr. Zwiebach, he is an amazing lecturer!!

now i can finally tell my friends that I'm doing some MIT courses :)

Happy Valentine's to you too!!!!

oh, FINALLY, I need it for my exam in 2 weeks. Zwiebach is a great Professor

I am Indian. Sir, your teaching Method is unique than other

Dr. Zwiebach just published his textbook "Mastering Quantum Mechanics". It covers the material in 8.04,8.05,and 8.06. The book is worth the price.

He's amazing, i wish someone told me MIT uploaded their lectures while i started my BSc in Physics back in 2016. I used to search for quantum mechanics lectures and RU-vid would never suggest me this. Then last year a friend of mine showed me the path to Quantum enlightenment with 8.04 and i haven't been the same.

Love this professor.

wow, great Quantum mechanics 3. Thankyou MIT. Thanks Barton Zwiebach

Thank you Dr. Zweibach

I love you MIT

Welp. This is exactly what I needed see'ing that Im in quantum II this semester :)

You are superb sir..

OMG, I AM GONNA LOCK MYSELF UP FOR THIS!!!!

Lovely, Thank you kindly.

He's from my country, it's an honor

This made my day Love from India 🇮🇳

No idea what he is saying but I love his presentation. I know for sure that he is giving an excellent explanation to those who understand what he is saying.

Just the time I needed to infinity frequency harmonics

Great lecture

Sir it's my humble request to make videos on the course of relativistic quantum mechanics..... your lecture is awesome sir..just awesome .....its my request to mit.... it'll help a lot

Please please, release a course on quantum information! Then everything will be perfect!

super clear Thank you

Go MIT!

30mins ago I was watching my Sagittarius star sign reading, then I watched the top 10 foods to eat in London, I've watched a poker vlogger in Vegas....and now I'm here. I think I've stumbled into matter way above my station. He might as well be speaking Japanese, I don't understand any of it....but I wish I did.

Zwiebach coming back!!!

Question for the part discussed at 17:06 , should the index k not start with k=0, so k element of [0,1,.....( ? I just got confused here, because the comparison of the Energies starts for k=0: E(0,0)

putting the video in 1.25 speed really improve the pace of the presentation.

you save my life.

One dimension in the spectral state Means eigenvalues follow a general para meter?Thanks but getting first view wrong interpretati o ns Thank u so much for the constructive lessons

thats pure gold

waiting for relativistic quantum mechanics and quantum field theory

III Playlist Length: 29 hours 49 mins

When did I understand a harmonic oscillator?

Can I learn QED after this course or are there any more prerequisites?

God damn this guy is amazing

Alllow me to ask u Please when always be On (0) means: where can we find independence? Is there such When comparing? Could u Please guide me maybe a previous lesson or books to reach a better understanding mainly in Hamilton's-oscillations-eigeinvalues function? Thanks!!

I am in grade 7 and understood

Curves that has energy

I applied to the institute. They'll publish the decisions in 2 hours, and I'm watching this to send positive thoughts to universe :D

the most priceless videos have the lowest amount of views.... how ironic!

Lovely

ANY BODE HAVE LECTURE ABOUT PERTERBUTION IN CLASSICAL MECHANICS GOLDSTEIN

Next QFT courses by mit please

So we find energy we have all Quantum computing

People who disliked better to meet psychologist....

@4:20 where the math starts.

if we face the trouble . we hope someone can hlep us.

Does anyone know what happens next?

do students record this secretly?

@15:38. NDPT

Mathematicians surely have a different understanding of degeneracy ^^

❤

I wanna study in MIT.

This guy is really first-rate, but I've got a slightly different question. What I want to know is, What does it cost us that we don't have an intellectual bridge over the very tiny but ver-ree deep chasm between the areas of industry where the quantum view is useful and the rest of real life where we live in billiard ball physics at voltages between about one and the latest in high-tension transmission lines?* As theories go, the Standard Model is pretty good. It gives us replicable numbers out to twenty significant digits or so, and it lets us mix the chemicals and what-not in ways that make an advanced industrial economy tick over nicely, thank you very much. So it has some problems? Like e.g. a total 100% inability to explain Bell's Inequality and a 99.44% likelihood of drifting off into mindless blither when anybody tries? So what? That's my question. Where is it costing us spondulix that we can't explain the two-slit-experiment? Where there's money on the line is where we'll find the intellectual band-aids to get us through the next generation of our view of physical reality. __________________ * There is a good fix for this supposed chasm, using the explanation that quantum reality is everywhere, it's everywhere, all the way up. I.I.Rabi famously calculated the likelihood of a normal masonry brick levitating a foot (a measure of length used in the United States, Liberia and Saudi Arabia) in the air in any given second. For an encore, he did the Heisenberg uncertainties relevant to trying to drive a ten-foot truck through a nine-foot gap. Both calculations come up with numbers like once in ten to the Q times the age of the universe, with Q being, uh, rather large numbers. The excellent Jim El-Khalili, who is well overdue to become Sir James, has some good lectures, e.g. ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-wwgQVZju1ZM.html&ab_channel=TheRoyalInstitution, on a parallel theme, that we see quantum effects at human scales in biology. (Google him: I think he might be in the running to be the Carl Sagan of the present generation of public science.) Neither of these life-rafts of sanity, however, comes with an answer to the intellectual challenge of Bell and those pesky interference patterns.

hi

just to high civilization and independent is 2 different issue. civilization link to the rule and order. if on rule and order. we need international police can enforce the rule . to protect the weak . independent link to lawless on bully mindset.

the topic should on the civilization. this link to rule and order set by the world leader. every country need to adhere the rule based policy. it is nothing on independent state issue. this prevent a military strong country. invade small country. UN is a civilization organisation we cannot stay alone. like nothing happen to us. we need to care for each other. having the same mindset on understanding live in this civilization. if nonindependent(selfish), the military strong country will invade the weaker country. like rusia invade ukrine. or china invade some big country draw the new desk line in asia. to invade a small country resources. this will bring us back to soviet era. big fish eat small fish.no more justice . this make ppl live in slavery life. this is not the way for civilization. just to highlight civilization and independent is 2 different issues. civilisation link to rule and order. independent link to self fish behaviour.we are living in same world. any thing happen will affect our survival. no country can alone.

ami porate chai

❤❤❤👍

Why do they still use chalk in 2019?

-10 pts to whatever physicist missed the opportunity to call "sophisticated degenerate perturbation theory" as "very degenerate perturbation theory"

cool

bruh i dont understand this for shit. i just played the video cuz its boring so i can fall asleep
