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!
In my opinion, college is just guided self-education. Works well enough for me, but it has some serious pitfalls when considering how much money is spent on it.
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.
There are neither particles nor waves here. There are only quanta of energy. Quanta give rise to a number of phenomena. A large number of quanta of the FREE theory (free as in free of self interaction) can give rise to mean field theories that look a lot like classical waves. Individual charged quanta can undergo annihilation processes but those are NOT part of the free theory. In an annihilation process we have at least two quantum fields (the charged fermionic field and an uncharged bosonic field) that are interacting with each other. Totally different physics.

@Thomas Abbott sure thing but that's not my point. Educational videos can't presume people will know the subject or it loses traction (and debatable its purpose)
Thanks for the suggestion. The best way to find out more is to visit the complete course site on OCW: ocw.mit.edu/5-61F17. Overall, this course is an introduction to quantum mechanics, but geared toward teaching concepts that will be useful to chemists.
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
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?

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.
Because white light is combination of different colours of light which inturn have different wave lenghts.... And we want monochromatic light with single wavelenth
Interferemce is observed when more then one sources of light is present or a sourece is split into two.... In this case we have oNly one source of ligt
Beacuse we want to observe....the number of electrons ejected from metal surface and their enegy for each frequency separatly.....so that we can analyse the data and conclude trend.... If we use many frequencies at same time(white light) we would be unable to fine result
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.
Connor Colestock read again what I said. If he's only reviewing the concepts and has already been taught ad nauseam, then it's fine. But if he's introducing these concept for first time, this certainly is not the best way.
Maybe it's on you to do a better job learning, you have access to the internet (obviously) it's not like you paid for the course. Education isn't spoon feeding.

@@adityavarma193 You're paying tuition only for a 'guide', network and a degree. And of course, some potential friends on the side.
I really liked that camera angle with the bokeh. Not sure if it added anything to the learning but it was beautiful nonetheless
Amazing content for free
Anyone else thinks this class went way fast because of how enjoyable it was??

Even though I’ve already took once the quantum physics class, I’m still so confused.....
if quantum doesn't shocked you ,or it doesn't confuse you than you are not understanding Quantum?
Is this a Bachelor level course or a Master level course?
This is an undergraduate course. For more info and materials see ocw.mit.edu/5-61F17.
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
17:30 I'll try that sir
Thanks ❤️🤍

why we don't use white light in compton effect?
Because white light is combination of different colours of light which inturn have different wave lenghts....
And we want monochromatic light with single wavelenth
If so , than we must see a interferance ..also...?? What you say about that??
Interferemce is observed when more then one sources of light is present or a sourece is split into two....
In this case we have oNly one source of ligt
Yup ....but again ,why we need to use monochromatic light?
Beacuse we want to observe....the number of electrons ejected from metal surface and their enegy for each frequency separatly.....so that we can analyse the data and conclude trend....
If we use many frequencies at same time(white light) we would be unable to fine result
Kind of surprised that in 2019, MIT still uses chalkboards. I went to Purdue in 1991 and they were using whiteboards even back then.
This is helpful ❤️🤍

weak. Perfect for learning. There are prerequisites that he is referring to, and which he expects students to raise their standard to.
Connor Colestock read again what I said. If he's only reviewing the concepts and has already been taught ad nauseam, then it's fine. But if he's introducing these concept for first time, this certainly is not the best way.
Why would he be introducing new concepts already? Also, if he were it wouldn't be a big deal. Sometimes there is just too much material to cover.
Connor Colestock learning something in depth is better than learning everything but having a shallow understanding.
Maybe it's on you to do a better job learning, you have access to the internet (obviously) it's not like you paid for the course. Education isn't spoon feeding.
