Following.. I love physics

Waiting for Bernoulli's theorem...fluid mechanics!!!
That formula of p1=p2

That is not a discipline in quantum physics

, dats in physics, i can't forget those equations o.

Hmmmm.. Not bad at all.

Lemme bookmark this page. I'll read it in the morning. I'm not usually that bright towards the end of the day. Lol.

@OP Quantum Mechanics is far difficult and complicated than the simple way you are describing it
Am a second class upper graduate of pure and applied Physics, so I know what am saying

The OP stopped at secondary school physics, you can continue from there

Anyone can make something more complex, it takes a genius to make the complicated more understandable in simple terms. What is the use of knowledge if only people like you understand it.

Quantum Mechanics in Nairaland? Okay o

Pascal law not Bernoulli

Or maybe, making things "complex" is nothing but "teaching" Quantum Mechanics here... My thoughts though. No offence

Yeah sure...but still fluid mechanics.. Thanks

We shall consider nonrelativistic systems consisting of a large number of identical particles. In order to treat these, we will introduce a particularly efficient formalism, namely, the method of second quantiza-
tion.

Nature has given us two types of particle, bosons and fermions. These have states that are, respectively, completely symmetric and completely antisymmetric. Fermions possess half-integer spin values, whereas boson spins have integer values. This connection between spin and symmetry (statistics) is proved within relativistic quantum field theory (the spin-statistics theo-
rem).

An important consequence in many-particle physics is the existence of Fermi–Dirac statistics and Bose-Einstein statistics...

Nice... But copyright is a crime even in Nigeria...

Physics arrrrggg

What Of The Step Potential, In One D ,2d 3d Harmonic Oscillator, Hermitian Operators, Orthogonality Normalization Etc Mehn A Whole Lot, Jst Love Qm,

I love quantum Chemistry....

Copyright infringement? Ok.

Una dey talk as if there is no complex side of every course...

Still waiting for someone to dilute for me machine learning in computer science.

We consider N identical particles (e.g., electrons, π mesons).

The Hamiltonian H = H(1, 2,... ,N) (1.1.1) is symmetric in the variables 1, 2,... ,N. Here 1 ≡ x1, σ1 denotes the position and spin degrees of freedom of particle 1 and correspondingly for the other particles.

Similarly, we write a wave function in the form
ψ = ψ(1, 2,... ,N). (1.1.2)

The permutation operator Pij , which interchanges i and j, has the following effect on an arbitrary N-particle wave function....

Checking again whether this is nairaland. I expected another "Two people met on the road and this happens" childish topic on the front page

Pijψ(. . . , i, . . . , j, . . .) = ψ(. . . , j, . . . , i, . . .).

Be reminded of a few important properties of this operator.

Since P2ij = 1, the eigenvalues of Pij are ±1. Due to the symmetry of the Hamiltonian, one has for every element P of the permutation group P H = HP.

The permutation group SN which consists of all permutations of N objects has N! elements. Every permutation P can be represented as a product of
transpositions Pij .

An element is said to be even (odd) when the number of
Pij ’s is even (odd).2

A few properties:
(i) If ψ(1,... ,N) is an eigenfunction of H with eigenvalue E, then the same
also holds true for P ψ(1,... ,N).
Proof. Hψ = Eψ ⇒ HPψ = PHψ = EPψ .
(ii) For every permutation one has
ϕ|ψ = P ϕ|P ψ , (1.1.5)
as follows by renaming the integration variables.
(iii) The adjoint permutation operator P† is defined as usual by
ϕ|P ψ =
P†ϕ|ψ
-
.
It follows from this that
ϕ|P ψ =
P −1ϕ|P −1P ψ-

=
P −1ϕ|ψ
-⇒ P† = P −1
and thus P is unitary P†
P = P P† = 1 . (1.1.6)
(iv) For every symmetric operator S(1,... ,N) we have
[P, S] = 0
and
P ψi| S |P ψj  = ψi| P†SP |ψj  = ψi|P†P S |ψj  = ψi| S |ψj .



Bye all.... Am outa here

sorry, there is nothing interesting about this branch of physics that the OP is trying to package for you guys.
It all leads to total abstract physics that you would end up confusing yourself.

The mod must be sleeping , a beautiful thread like this didn't reach the front page since last year. Oga ooo. OP welldone

Nice one op

God bless the OP. I spent the whole of 2013 studying quantum physics, it's application to me as an individual trying to make a quantum leap myself and I was amazed because quantum physic revotionalized science forever. It summarizes all of science and opens a new Vista.

Shout out to my Secondary School Physics Teacher, that man made me hate Physics



All the same we passed

Quantum physics? oh dear! poor me. my head is spinning and I think I need a doctor urgently. It may make more sense to junior.

Did quantum chemistry in Unilorin when I was in 300L, Taken by Dr rabinowitch and Dr eke Now a professor. I just hate this damn topics. It's like magic To me plus the 2 lecturers makes it so boring. All those Schrodinger equation. And So many annoying signS. Ended up having D. (46) Omo I thank My God. Alot of people dey carry the course

all i knw abt anytin quantom physics is that there is a large hydron collider also known as particle accelerator which allows particles to collide nearly at d speed of light.

Man I love this,I wanna see more.

Good one.

promqueen247:
This is real knowledge here. Albert Einstein even made wrong assumptions prior to this topic. quantum physics is very advance, complex and broad.

U try.....all I was expecting from the females in this thread was a single word comment like..hmmm!, intresting , nice , educative, informative,following...no offence to the ladies, I ddnt like physics either back in d days mama had to fast and pray for me before I could get a B3
