@stevemuller8320 Says:
btw - the famous Schrödinger equation can be easily derived from the Euler-Lagrange equation:
**1. Euler-Lagrange -> Wave Equation**
delta Integral L d3r dt = 0 => nabla^2 p - (1/c^2) d^2p/dt^2 = 0
(Variational principle -> Acoustics)
**2. Standing Akustic Wave (Helmholtz)**
p = psi * cos(omega * t) => nabla^2 psi + (2*pi/lambda)^2 * psi = 0
(Temporal harmony -> Spatial amplitude)
**3. De Broglie & Momentum**
2*pi/lambda = p/hbar with p = mv
(Matter wave -> Particle momentum)
**4. Energy Substitution**
p^2 = m^2*v^2 = 2m * (1/2*m*v^2) 😉 with 1/2*m*v^2 = K = E - V
(Kinetic energy -> Energy balance)
**5. Schrödinger Equation** 👍
nabla^2 psi + [2m(E-V)/hbar^2] * psi = 0 => -hbar^2/2m * nabla^2 psi + V*psi = E*psi
(Synthesis -> Stationary states)
Define H = -hbar^2/2m * nabla^2 + V => Hpsi = Epsi
(Final Operator Form: Hamiltonian * Wavefunction = Energy * Wavefunction)

So being. Simply is god bored now.
Yeah he bored himself
@maneeescu Says:
I do Believe that not only New Universes are created. They are always created.
But beings are limited.
What is being
@maneeescu Says:
You did not understand that I can predicte and create everything
and 8know pi

the new universe is NOT a new Pi

Being compared to Euler is epic. W Derek

While I was a 3.79 student in university, I found each time I tried to further my education, I was challenged by some external source, politically, legally, financially or even physically and to a point of purely just surviving.
It's more difficult to halt my inclination toward self-improvement if the requirement is to block my access to this (and similar) YouTube channels.
Thank you!

Bro changed the title 😂😂😂😂😂😂😂😂

It is comprehensive
@R3verrrr Says:
So close to verifying theory of everything
@coolhacker71 Says:
nice work. now make a theory of everything 2.

Theory of everything... god

Great video, I really enjoy watching your videos, especially because of their length and high quality.
Talking about action…
I haven’t really known about the concept of action and I don’t think that I will in my next few years at university and I first heard of it when I watched a video of yours not so long ago, I think it was about the Ahranov-Bohm effect.
Hearing that the action principle wasn’t really taken serious in its origin due to a lack of reasoning, I thought about how you could reason That lowest action is what to be achieved by nature.
I came to the conclusion that lowest action means lowest energy input. You want to travel further=you would have to use mit energy, you want to travel faster= you would have to use more energy and the same goes for heavier things.
So in general the action formula is about doing stuff with the lowest energy input.
But that doesn’t seem right regarding that physicist at that time weren’t thinking about this, so my question:
Why is my thought wrong, what makes the action principle so complicated that it isn’t trivial as I perceived it?
Thanks a lot to everyone who is kind enough to help me find an answer :)

a theory of everything... you say...
@PaulDirac-p4l Says:
20:52 are you talking about local minima? that çis an interesting topic...could we have a video on that? thanks

@gdrgersegegewr Says:
i need some thinking space for this theory of everything
@goopeltydoop Says:
its almost like this Theory of Everything needs a version 2, a Theory of Everything 2, maybe it'll help us understand things like a Time Machine and the Hexagon Force in saturns poles. We'll need to be Deadlocked on it to make this and go through the Grief to find the solution. And we would be Back on Track to advancing as a civilization.
@Alex-2-6-3-5 Says:
MMH i feel like we are kinda getting Back on Track but i cant tell
@RubenStormMusic Says:
Physics really does feel like a centuries-long argument over who found the slickest shortcut. Still waiting on Theory of Everything 2.
@TheMotionTheory Says:
Motion Theory.
@ThePetster Says:
prob the biggest GD reference of all time
@ThePetster Says:
Guys, lets just get Back on Track
@PremaLatha-gk6ke Says:
you know your theory is good when THE Leonhard Euler defends it
@Zabloing707 Says:
mr verity assium is probably hella confused if he looked through these comments
@compiler_0 Says:
Does anyone else out there realize this isn’t continuous mathematics really?
It’s topology on a different representation system IMO
Is reality a point cloud? I dunno either.
@hahahafiy Says:
What that's CraZy
@SalzmanSoftware Says:
The principle of least action can also be used to describe bro’s love life; because bro ain’t getting no action
@FrumentumMC Says:
nah... the league of dashers in the comments
PS. guess who's at the bottom of bloodlust record holders :)
@hoebackytblademan17 Says:
say that again
@Zone-nfl Says:
we are gonna make a time machine before a theory of everything
@0biwan7 Says:
20:17 for 35 years i never understood how T-V related to action because that was the definition. now i can see it is momentum time distance subject to the constraint that energy is conserved.
