1. Quantum Mechanics-Historical Background, Photoelectric Effect, Compton Scattering 

starts at 8:59. 10:51 spectroscopy encodes what we need to know about elements; 12:15 matrix model is more usable; 16:27 interference

I love evening tests. Keeps me out of the bars.

I really liked that camera angle with the bokeh. Not sure if it added anything to the learning but it was beautiful nonetheless

Loving your class Professor Field. Thank you 〰〰〰➰〰〰〰🔛

awesome! Great lecture.

What such a kindness . Thank you .

16:46 “Particles… Can annihilate each other“ waves don’t annihilate each other. Destructive interference is not destruction. It’s a temporary illusion of destruction.

I Dont understand 37:22 where Sir Field says that (h over mass of electron multiplied by C) is momentum transferred, this contradicts the first statement he made that the (h over mass of electron multiplied by C) has the dimensions of wavelength! Im confused

Anyone else thinks this class went way fast because of how enjoyable it was??

The best thing about the Internet is that you can learn from many different people. I started this video and then skipped through, and this guy reminded me of when I had to rely completely the on the assigned book. I scrolled to the comments and at the top and I see people commenting about how he is hard to follow, or say he should teach in a certain way. I just want to post and let M.i.T know that if that want bright minds doing research and studying cutting edge subjects that perfectly fine. but how are we the next generation to take over the work if it not being taught right. This video is evidence that a lot of top schools don't have the best teachers they have great student that will go through hell and high water to understand the subject. Please make it easier on your student and hire people who can teach. and keep the people who are just good for research in the lab away from people where they belong. also a pay cut. why give them a check for teaching if they can't teach? give them a check for being a researcher only!

17:52 “What is new?“ In general it is considered impolite to use double meaning.

Amazing content for free

Great! 🌸

1 Electrons in solid entangled such that their spin all are up /down. In Liquid alignment are mixed. In gaseous state spins are untangled. Viscosity may be promotional to ratio entanglement. B-E condensate all entangled electron are either up or Down 2 E= mc squared. And plane Plane kinetic energy is partially converted into potential energy because of buoyancy in air. What could be the medium in e= mc2 if any involved.vhiggs field or quantum field are possible candidates

I'm Mechanical Engineer student ... Loving all type of scientific lecture ... 😊😊❤️🌹

16:58 QM exploits that particles can cancel each other

why is there a delay between E and B field?

It's not clear from the title of the lecture or the intro that this has to do with quantum mechanics - maybe that could be updated? I get notified for MIT OpenCourseWare RU-vid videos and usually find time to watch - because they're generally exceptional. But before starting to watch this video I had no idea what "historical background" referred to. But glad it's quantum mechanics so got lucky this time :)

37:01 Compton wavelength of the e.

just in the last two days I saw a new discovery of a material that changes drastically it's insulation/conductivity properties with a magnetic field. what would cause that to happen?

please make a playlist of all the videos in this lecture series. Thanks!

Even though I’ve already took once the quantum physics class, I’m still so confused.....

will be able to put subtitles in Spanish?

How does the camera capture your image?

Fresh = Se-gar Im-aging. When I want to write Lily, the image of Mr. Weigener holding a cigarette with his right hand appear. Q.M. is something else. N.

i'm from Egypt doctor and i'm seeing the lectures

好大的板擦，強

feeling perturbed ;)

Please could someone tell what is the books name and who write it ,as sir Showed in beginning of lecture

is this class part of the Physics degree? or the Chemistry degree?

17:30 I'll try that sir

Suggestibility..?

Is this a Bachelor level course or a Master level course?

chemist love talking about the double slit experiment

Why is time taken to be invariant when conducting experiments?

1080p is permium .😮

25:55 “particles” 👎. why “particles”?????

10:51

See matter as Loose association of things.... The ultimate unit....may...doesn't have to be one thing.....isnt it human.. Maybe a collection....std mdel?

#QuanNoQuit!

why we don't use white light in compton effect?

He shows some books. I can't ride the titles of those books, anybody can?

Bsc.....neural.... Oflactory.......in the lecture.... I sensed Intel... Then.....friend...or No foe... Oflactory end Learnin initiate..

What are the books prof suggested?can someone name them?

Third

Incredible that his voice holds out for 36 lectures. Be careful, sir.

Kind of surprised that in 2019, MIT still uses chalkboards. I went to Purdue in 1991 and they were using whiteboards even back then.

شباب اكو احد هنا لو اني هنا وحدي ؟

with all respects, he speaks so slowly that at 2x speed, the video sounded super normal

Arya let me smile....easier..

17:39 “What is new?” “it’s C over Llamada”. 😢😢😢I listened to this twice. And then I got it. It’s a dad joke. does anyone else get it? i’m actually personally against making jokes during a lecture. Unless you specify that it’s a joke. Because the material is so difficult and basically impossible to understand, that this distraction is extremely frustrating. I see this behavior from many professional academics. It feels like a little patronizing and in general it detracts from the learning experience.

real life walter white

Lecture linguistics.....try not to tie in life to learning quality.....like learning isn't everythin...like money isn't....death anxiety....

Bad start to the class. Lacking proper introduction and interesting examples. Usually a problem with most PChem instructors

I won't like if my professor start teaching me like this. He's just throwing out concepts without giving any insights. Maybe it's a review class that's why he's only giving mathematics equations and different concepts but if it's first class. I would most definitely not take his class. Physics without insight is plane Maths which is boring. He should supplement various equations with experiment and thought experiment so that audience can develope an intuition about quantum mechanics. Of course I'm not new to these concept so it's a breeze for me but someone who's just learning this. It's nothing more than just many mathematics equations and subtopics of quantum mechanics.

Interesting....students trained for disbelieving even confirmed science......better pedagogy?

First

Love the lecture but the Prof sounds like he is going through puberty, or needs a cough drop and glass of warm water. But very good course.

Please someone tell what is the books name and who write it ,as sir Showed in beginning of lecture
