why probability in QM? |
What I'd like to understand is how scientists use probability
or wave functions to solve problems in physics. It is stated
that quantum mechanics can explain all there is in the
world. Can you site an example where a layman can understand.
I've been reading some college Quantum Mechanics books but
couldn't understand the complex math principles. I just
want to have a rough idea of what it means that a certain
electron will have probability to be somewhere, etc.
How do you use this to solve the quark, pions behavior,
rykman scaling, nucleus physics etc. I mean what has it
go to do with probability of the electron to be somewhere
and adding this up. How does adding up individual
probability predict the behavior of the end points?

Library. Google. Shift your lazy *****.

Not gravitation, not at all. Don't try to synthesize aspirin using
quantum electrodynamics. QM isn't any good for hitting a baseball or
making the GPS system work (aside from its electronics). QM won't get
you the hot chicks, treat constipation, or make the cat come when you
call it. (Uncle Al's cats heel, mostly - a fact that infinitely
bemuses the neighbors when I walk them.)

An uneducated layman? No.

How does one remedy this?

Exactly that. You look. What chance is there that it will be there?

Babies should not be given loaded guns (unless in overcrowded
daycare. Think of it as evolution in action).

I gather that goes under "applied physics":-)

yes.

and ??......
after going to the library
can you Uncle solve basic facts ??
can you prove that the Lead atom has 6 shells of electrons
and in addition subshells??
if yess please brnig your mighty search abiliy
here and you get a prize of 100000 $

An uneducated layman? No.
he migh tbe an unsducated layman
yet yoy are an educated ignorant + damn arrogant.

Then read a textbook on QM. They are full of examples for that.

That would be wrong. E.g. when gravitation comes into play,
Quantum Theory has huge problems.
Can you site an example where a layman can understand.
The spectrum of hydrogen can be calculated by QM. Do you
know what a spectrum is?
I've been reading some college Quantum Mechanics books but
couldn't understand the complex math principles.
Well, if you don't understand the math, then how could we
be able to explain to you how QM is applied???
I just
want to have a rough idea of what it means that a certain
electron will have probability to be somewhere, etc.
It means just what you said. Could you please clarify
your question?
How do you use this to solve the quark, pions behavior,
rykman scaling, nucleus physics etc.
We solve the corresponding equations. So if you don't
understand the math, it's hard to explain what we exactly
do.
BTW, what is "rykman scaling"?
I mean what has it
go to do with probability of the electron to be somewhere
and adding this up.
One does not add up probabilities for the electron to
be somewhere. Probably you confuse this with Feynman's
"sum over paths".
I recommend his book "QED" to you. Perhaps that
will help you.
How does adding up individual
probability predict the behavior of the end points?
What exactly do you mean with "end points" here?
