[Quantum Mechanics, Ladder operator, uncertainty princple] computing uncertainty relation for Number and Phase operators
So the question is like, lowering operator is expressed in terms of N and Phase theta, and I am supposed to calculate the uncertainty.
Ok heres what I did.
to find uncertainty, you need expectation value of the commutator, but for that you need operator definition. Nhat I was able to write as a(dagger) a
But I having a head banging a long time, trying to find phase in terms of ladder operators.
Also is this even correct, finding uncertainty relation from expectation value of commutator sounds dubious IS THIS REALL!?😭
Slowly and painfully losing my interests in PHYSICS
19 India Second year of UG
A few years, ago I thought I would be a theoretical physicist, even though I didn't know it even meant. I barely know what it means now. Overall there is a log decrement of my interest in Physics. After I failed an entrance test for the tier 1 college for physics. I chose maths over physics for my major in ug now, I still can do msc in Physics, but it will more difficult.
My reasons.
- After seeing my peers and close ones clear exams so easily and seeing them do MSc and PHd, I am humbled down, and then more till i was in the freaking mantle of the earth
- Overall loss in the subject.
I started to reading Quantum Physics for that reason now.
It just feels like this is not for me. I mean I have been a good student, not just because I got good grades , but I was naturally curious about the subject,
BUTT THEFREAKING JEE and other entrance exams ruined everything. I might be good learner but i need time. Till it took me time to understand one concept, the classes were teaching a new one and just shortcut ways to solve problems. And

Why THE HECK a accelerating charged emits radiations whats its dealo.??
AND THE whole Atom models things.I mean alright I understand the angular momentum of electron is discrete,
but atleast EXPLAIN, why won't that electron sprial towards the nucleus( why wont it emit radiation if it is in that L )
Also I am sick and tired of having to 'hear' people's slightly repulsed expressions when I tell I am doing BSc.
peace
New to the sub, I have read only a handful of books, only two actually from classic literature!
I have read Crime and Punishment english translator was not credited, but i think its Friedrick Whishaw, loved it, (wonr say understood it though) started rereading it now, half completed the Idiot. Had started reading Moby dick, (Reached to the part where both of them are surprised to find each other in the bed) laughed off my ass on that part😁
i dont think Cuckold, will be in the classics but completed more than half of it. Read Kalfa on the shore, gone girl as well...
Give me your best! 😊
Denying my identity(Intelligence) because of 1. Conformity 2. Cowardice induced by people much more intelligent than me,
First of all, looking at all the other post, my problem sounds like a trifle to me now.
I live a really appreciated life. I have good friends and all. The problem being that I am at least better than the average people, in academics and I not saying that statement with any pride associated with it sadly it is a fact and I am tired of pretending its not. That's the start of the problem... Most of friends if not all, try to glorify me, which I absolutely dislike, calling me Einstein and what not, which just makes me repulse. I do not like being glorified, it just cuts me from being one with them, every time I used to say something, my thought was turned on its head and made into a punch line about me being so smart. This was happening were since I was a preteen. So cut forward to today, I have toned down my vocabulary, I don't bring up my thoughts of various topics I loved to talk about, including fiction, movies, western classical music, physics, maths. I love dancing I have been wanting to learn waltz. I have tried to make them realize that I am much more than they think, but I believe attempts in that direction are in vain .Now of course the solution to this to find myself a friends which have similar interest as mine. That where the second half of the problem begins, I have met and seen people much, m u c h more intelligent than, and of course I have interacted with them, and made friends with them. However after realizing the vastness of the gap between them and me, I felt afraid, afraid that I will be mocked, and thus stopped all active attempts in finding them, however yesterday I was trying to make my friends realize that we have a lot more common than what they believe, but after pondering over it myself, I realized that I was wrong. I am suppressed all of my thoughts and stopped documenting them as I used to. BUT yesterday I realized that I make put myself in a cage of my own making, Just think about it Albert Camus, Simone de Beauvoir, Satre, Picasso were FRIENDS, in the sense that they used to sit together and talk, HOW FUN that must have beeeen!
How happy must I will be too, If I find a girlfriend, whose as interested in talking about the 'stuff'
Thus this post is make beginning of breaking the cage of my own making to fid more people like until I become a
free bird

I feel this is not the subreddit where I should be saying this?
