Particle in a Box Part 1: Solving the Schrödinger Equation 

but still i didnt get the ans for my required ques.

Hey from which university (if it's not lack of discretion)? Je cherche un master également... Cheers

bro

wow, Lois by now post-covid u-must-b a Math wizz!

@Lucas Shepherd yea but u gadda 1st no their user name!

@Lucas Shepherd ive seen this comment spammed in every comment there is on existence

yes check the modern physics playlist, the last 4 i've posted have been part of this miniseries on a more rigorous approach to quantum mechanics

@@ProfessorDaveExplains I love you so much...♥

We followed this path in the physics studies... the real satisfaction was when we calculated our first Hydrogen atom and Hydrogen molecule, and the energy levels of electrons. and than we compared it to lab measurements to see, that all that mathematical abstraction were actually representation of something very real and very fundamental. A true "feeling like a god" moment in life.

@@meleardil That's the beauty of physics :)

@@ProfessorDaveExplains sir can you plz explain : psi=Asin(kx)+Bcos(kx)? How did it come? How to prove?

hi...can you plz explain : psi=Asin(kx)+Bcos(kx)? How did it come? How to prove?

can you plz explain : psi=Asin(kx)+Bcos(kx)? How did it come? How to prove?

Is there a link that solves it step by step, im a chemistru student and i do not have a clue how psi = a sin (kx) and B sin (kx) , every single video just assumes thats the baseline

@@mehmethanbuyukdag3245 there are, but this setup gives a fairly simple PDE that can be separated into x and t equations, and then transforms to an ODE. You may not get much from a step by step if you have little to no PDE (and ODE) experience. Here is one that will carry you much of the way ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-Dt_VKsSggAo.html Important thing to know is the exponential identity e^(*/-)ix = cos x (+/-) i sin x

@@cguy96 thanks a million Mark :) much appreciated

@@mehmethanbuyukdag3245 The wave equation is just a 2nd order homogenous linear partial differential equation ( I know that sounds insanely complex but its not as bad as it sounds) . This differential equation can be solved by using the "characteristic" equation method. It just requires subbing e^(rt) in for Psi ( you will see in doing differential equations how incredibly useful Eulers constant and Eulers formula is). Subbing this in, and doing the derivatives leaves you with a quadratic, where you may simply find the roots, and plug them into the characteristic formula. You will get complex roots and using Eulers identity (e^(ix)=cosx+isinx). After some algebraic manipulation, and dropping the "i" term (which you may do because the solution is a real value solution), you will eventually arive at Asin(x)+Bsin(x), then just plug in the proper variables.

Damn, I'm trying my best to decipher this coded message!

That's very interesting! I feel certain it's based on the book the Revelation of Jesus Christ to St John from someone who understands that it's all about us individually. The quartz crystal is the new Jerusalem which is a transparent cube with 12 pearl gates. I happened to see on the weather channel a couple of weeks ago how salt cubes are being generated by the dead Sea because it's drying up. I think there is a lot of meaning in the choice of making him a square root symbol. The odds are you think I'm off my rocker but if you are interested check out the last 5 or so pages of the book of the Revelation.. I think the pearly gates relate to our twelve cranial nerves and 12 perfected cell salts as salts seem to automatically seek their perfect match leaving irritant matches for matches that can only be broken in water to loosely paraphrase Walter Russell. Salts are made from the Halogen elements with a metal. I'm sure this is connected to halos, may sound crazy. The river Jordan represents our cerebral spinal fluid which is the river of Life. This river empties into the dead Sea. The 12 cranial nerves flow through and out the Spine in a way I have to say grosses me out a bit because I don't like the look of how this looks like roots coming from a tap root but that is what they are, the roots of the tree of Life. Anyway, don't worry if you aren't interested in what I say for any reason. I am interested if there is anything else you think I might find interesting about that game. 🙏

You'd probably want to watch a video on finite potential wells and quantum tunnelling then. There's not much real life in a infinite square well.

Please look into “Auxiliary differntial equations”. Luckily, this is one of the easiest types PDEs to solve. Good lick

@@qur4334 شكرا، و الحمد لله تمكنت من فهمها و سأسعى لتطوير نفسي من أجل خدمة وطني و العالم إن أتيحت لي الفرصة،

yep i'll probably cover that a bit later
