NMR is the craziest shit ever. I don't know how deep down the rabbit hole you got but understanding stuff like coherence pathways and 2-3D pulse sequences, is just too much for me. Thankfully I can still run spectra.
@believe German K5 Ok i Will try. First of all spin is the result of a famous experiment, the Stern Gerlach one: in their apparatus, briefly put, a beam of energetic electrons (like a laser) goes through a narrow path between magnets (a non-perfectly uniform magnetic field) and the path results split in two paths (up path and down path) at the end of the pathway the electrons took. This baffled scientists. Others eventually could even repeat with a very low flux of electron (imagine one electron per second) and the electron had a 50% of either going up or down. This killed determinism, even from a statistical physics point of view: how could an electron go either up or down? Then the electron must live in a "spin" state which is 50% of the times up and 50% of the times down. Spin up, spin down. How does the electron "decide" whether it goes up or down in the Stern Gerlach apparatus? Well this is the beginning of quantum mechanics. Spin is one of the seeds of quantum mechanics and its postulates! I can suggest some readings like Griffiths introduction to Quantum Mechanics if you would like a very soft intro to QM, or Shankar Principles of quantum mechanics for clear statement of the axioms, or even Introduction to Hilbert Spaces with Applications by Debnath if you want a formal axiomatic introduction to quantum mechanics. Briefly speaking, spin is a quantum "magnetic dipole" property of fundamental particles, and leads it to the quantum interaction with magnetic field. An electron can be both spin up and spin down until a measurement is made (such as stern Gerlach, it blocks the spin to either up or down after the magnetic interaction which counts as a measurement by the environment). Have a great day :)

I swear re-watching your skits and relating to it more and more each time is the best crap. XD I started watching your stuff as an undergrad and I'm a grad student now, so it's just really fun.
Here's something funny and from personal experience: When I was learning quantum mechanics in college, it made absolutely no sense to me. But when I took the quantum class in grad school, because they go over the calculus in much more detail (Hence why you need the Dirac notation), everything suddenly became a lot easier to understand.
Im sorry dont you immediatly use dirac notation in your grad class? Because im a 3rd year physics grad and in my QM class we immediatly started going deep with Dirac notation, bloch rapresentation etc... sounds weird to not use diracs notation in QM
The question on ‘spin’ had me 🤣 I studied spin chain systems, and when I was asked by the panel what exactly is spin, they got a mouthful of word salad.
The part where you pulled tons of books as graduate student to solve a simple question is so true!! 🤣🤣 I literally bury my desk in heaps and heaps of library books 🤣🤣

The answer is written in the Ancient Scroll. First law of Spin: He who thinks he understands spin does not understand spin. Second law of Spin (Palpatine's theorem): spinning is a good trick.
The spin question is so true. Also I noticed the 1/137 finestructure constant and then the pi/137 reference to the cgs-system, where you just move multiples of pi from some equations to others, just so that some of the equations in electro-magnetism look a bit easier.

“One of these books has to help me...” oh man too accurate
"Pretty easy stuff, only Andrew missed it"
"What? Oh yeah I said it was zero"
You have no idea how many times this exact situation has played out.
"Only andrew missed it" lmaoo. Great vid andrew
Thank you!
"I quit"
Most grad students have that one moment where we're like "You know what? F**k this!"
If any professor says, “you were supposed to assume...” they don’t know how to teach the concept they are expecting you to assume. Fact.
Foundations of Advanced Introductory Physics for Beginners 3: Grad Student: "Hey Prof, what's the recommended book for this course?". Prof (in thick russian accent): "Book? There is no book"
(then recommends Landau and Lifshitz on course web page as the only reference).
If russian prof. doesnt recommend Landau and Lifshitz then he is not russian
I see you are the lucky one. My professors recommended a book that we never use at all and it was expensive, and upon reading the author, it was my professor. Freaking cheap way of making money.

Quantum Geology? I must be tripping 😂😂😆
Between that and Relativistic Astrology, we've got a winner :)
Quantum Field Biology
Thats when the stone is still on the table and laying on the floor at the same time.
The concept of quantum geology terrifies me. Is the Earth just going to pop out of existence from above me?
@@helloim3j Just keep measuring it and you will be fine.
Good to know that grad school is pretty much the same in every field
true, same for chemical engineering. Was so funny lol
Its a cake walk for accounting.
Professor: Does anybody have any question so far?
Students: (Eyes on the desk to avoid eye contact with professor) ...
Professor: Good! We are now moving on to next chapter which talks about...
We actually skip the next chapter (although you probably ought to read it during the weekend, do all the related problems and get another book as this will be on the exam) and move on to something completely different.
@@u.v.s.5583 Professor: I am sure you all must have excelled at this course already, now let's digress into some interesting physics in different dimensionalities.
You can only ask if you understand something. Not if everything is a question. Then yes, it's avoidance land from then.
"Ohhhh yeah I said it was zero"
-Story of my life
So true.
Bruh, too many times. 50/50 on whether it's 0 or infinity
Same here five books on the table snd none of them help 😂
When he said “ One week for an assignment, sweet” I felt that.
I swear re-watching your skits and relating to it more and more each time is the best crap. XD
I started watching your stuff as an undergrad and I'm a grad student now, so it's just really fun.
Here's something funny and from personal experience: When I was learning quantum mechanics in college, it made absolutely no sense to me. But when I took the quantum class in grad school, because they go over the calculus in much more detail (Hence why you need the Dirac notation), everything suddenly became a lot easier to understand.
Im sorry dont you immediatly use dirac notation in your grad class? Because im a 3rd year physics grad and in my QM class we immediatly started going deep with Dirac notation, bloch rapresentation etc... sounds weird to not use diracs notation in QM
I felt the same when began to read Sakurai.
"Foundation of Advanced Introductory Physics for Professional Beginners" im-
This, though I know little about physics, was great! Glad I found this channel!
The question on ‘spin’ had me 🤣 I studied spin chain systems, and when I was asked by the panel what exactly is spin, they got a mouthful of word salad.
Please do more, this was great!
Thank you!
The part where you pulled tons of books as graduate student to solve a simple question is so true!! 🤣🤣 I literally bury my desk in heaps and heaps of library books 🤣🤣
I must have watched this video at least 5 times and this is the first time I figured out that Andrew was saying Dirac Notation not Direct Notation
Very funny!!! Typical physicist humor. When I was an undergrad I had some physics major friends and I would hear these sorts of jokes and stories quite frequently.
Loved the line on the whiteboard about Foundations of advanced introductory physics for professional beginners!! 😄
1:42 "One of these books HAS to help me with..."
No, no, they don't and they won't. Almost two years in grad school and I still struggle with that harsh reality.
TIL that my undergrad profs teach the class like a grad level course.
Love the way you deal with it... makes physics interesting....
Make more of these..
We love you...
thank you very much...
These videos are hilarious. I graduated with a BSc. in physics in 1999. These really take me back. Keep them coming.
wholesome comment
This is one hell of a video I've watched in ages. Please please please keep making such videos. From 1:33, I got a big big woaaahhh. We used to study from Griffith's as well during undergrad and I remember sitting in the library with I guess 4 books opened for the homework of my graduate school electromagnetic theory course 😂😂
Totally totally dope video. ❤️
Haha dude I seriously love these kinds of videos you're so creative. Hope you're doing well in that reletavistic astrology class😅
Thanks a lot!
Cosmic Nihil *relativistic
@@sunshinedaniela8572 Thank you for catching that. I don't remember if that was suppose to be part of the joke, or just a typo I didn't catch lol. Thanks regardless.
These are so good, and they really make my day!
Even as just a chemistry professor, I can vouch for the amusing accuracy of this!
As a physics student, that moment when you can’t find answer or any resemble hint from any sources is so relatable😂😂 I dig into tons of books and online research papers yet I finally give it up
i literally watched this twice because its so good
I enjoyed this. This is valid for nearly any grad student and you should think about expanding it. Nice work.
i effing love these videos. thank you very much baha
"Relativistic Astrology" lol
Good old Griffiths
Man I was up studying and I just came across a bunch of your videos hahah they killed me! Love them. Especially the spin part xD
Not only was this video golden and achingly true, but I was mostly staring at the class titles on the whiteboard this whole time laughing my ass off because each one just hits so freaking hard 😂😂😂 God I cannot believe this is my life
But... what is an electron ?
A cloud of probability
@@marcioamaral7511 that's the most cheesy way to say that 😂😂😂
@@llawliet2734 He wanted na answer LOL
The lightest spin 1/2 fermion.
A point charge.
I died at the “what exactly is spin?“ part.
Professor, screaming internally: "STOP ASKING THIS I DON'T KNOW EITHER!!!"
The answer is written in the Ancient Scroll. First law of Spin: He who thinks he understands spin does not understand spin. Second law of Spin (Palpatine's theorem): spinning is a good trick.
The spin question is so true. Also I noticed the 1/137 finestructure constant and then the pi/137 reference to the cgs-system, where you just move multiples of pi from some equations to others, just so that some of the equations in electro-magnetism look a bit easier.
This somehow reminded me of my 5 essays I have due to this week. Thank you my man.
I’m at my last semester of uni, getting my degree in History in a couple months so let me say this is interdisciplinary lol
" One if these books has to help me with this stupid homework" Hit so close to home
This mans videos jokes are often literally true for me and/or my friends in the physics major
I started physics grad school this year and this video feels so real, I almost lost it with the Dirac notation joke because OMG YES
U actually nailed every one😅....it's a really funny world isn't it....
I do maths, not physics, but all these jokes still apply perfectly to my classes. My maths heart goes out to all of you physics peeps.
StNick119 I’m also a math major and all of these apply in some way or another and it’s hilarious
One could say maths homework is a TRIVIAL pursuit. trolololol
physics is advanced math lolololololol
It shows my progression as a physics student that I now perfectly understand that last joke :D
You should definitely make more physics videos like this. Thanks.
The "Searching for a book or resource that will help with a homework problem" applies to every graduate degree :(
0:53 I probably laughed harder than I should have, my throat literally hurts now.
The dichotomy of beginner and expert - classical display, I'm convinced.
You're like real life xkcd
Experimental String Theory? Now I find out one thing to ask for Santa as Xmas gift, thanks.
"What is spin?" -Everyone in my undergrad medical biology program's medical imaging course
Love these joke videos 😂
That question what spin is really got me laughing. I only understood it in my masters when I had a really good professor. All the other ones before never truly answered it fully
That homework bit is tooooo real. Twenty books from the library and they are all useless
