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!

Hi, there are two versions of 8.04. which one you have watched??

[@jjheske]

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!

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, KZbin/Google. These are not only not evil, but actually, positively good.

[@harshitabhuyan8892]

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 KZbin 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.

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.

[@martinm.6472]

Well, you could but it's a lot of work.

[@kirktucker8183]

I can speak fluent Japanese and I can also understand this. All you need is to motivate yourself and remember what your goal is. What are you trying to achieve from learning perturbation theory? For me, it crosses into my interests of mathematics, linguistics and computer science. If you want to learn Japanese at some point, I have advice for that as well.

[@1998aida]

What advice can you give about learning Japanese? I am very passionate about learning new languages, have a nice day :)

[@durpdurper2768]

[@21vision]

Durp Durper alright, since you can make it simple, is there any way to fit all the theory given in this particular lecture in one simple life example which would be explicit enough for a non-academic person. I mean it would be easy to follow if a lecturer would show how this theory can be applied to a real life problem, either from technology or business field.

[@durpdurper2768]

Yeah, you chicken dance until you get real good at it.. or collapse, or something, or something else. Let's find out shall we.

[@JohnFerrier]

You need to have a certain level of physics understanding before watching these videos. SHOs are the most basic example of a Hamiltonian. I'd suggest watching some lower level physics stuff first. Maybe watch a series over classical mechanics first.

[@TheDavidlloydjones]

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. kzbin.info/www/bejne/rajKgomQn9pkkK8&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.

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.
