Default Rest mass or inertial mass?

Radi to all
Please, define your mass in the spirit of operationism


This is the way I do it step by step.

1. I take length and time measurement to be understood as basic from which one
can understand the concept of wavelength and speed.

2. I define the momentum in terms of wavelength.
p = h/lambda or if you want it in terms of components then in terms of the
wavelength k "vector".

Radi to Waite 310046
Sorry, you are not right in the head!
There is no operation to measure the de Broglie wavelength of a body
or of an individual particle!

Default Rest mass or inertial mass?

Pmb:

Radi is 100% right here. In fact "wavelength of a body" is not meaningful -
it only has a statistical meaning.


That's nonsense. The pion mass, for example is given by the
range of the nuclear force:

M_pion = hbar c/r_0

r_0 is just under 1.5 fm.

"I define the momentum in terms of wavelength"

The quantity r_o is not the wavelenth of the pion. It's the range of
the Yukawa potential,


E^2 = p^2 + (mc^2)^2

(\hbar w) = (\hbar k)^2 + (\hbar k_0)^2

Now, where do you think the "range of the yukawa potential"
comes from?

and that, in term, determines the shape of the
Yukawa potential. The quantity r_o is defined to be the distance where
the exponential in he Yukawa potential falls to 1/e


Do you simply copy words from textbooks without reading the material
or trying to understand what it means?

Honestly, is that English?

You forgot to square the first part sparky

This is a good example of when you should think twice about posting a
flame like this sparky - And you never did state why you have this
need to flame - Why is that?

Anyway - I posted warnings here about this directly to you and you
ignored them. And here you are making the mistake I warned you about.

E is usually used to represent total energy. In this case E = hbar*w.
But the correct relation for the 4-momentum magnitude is

(E - V)^2 = p^2 + m^2

Where E = T + V

where T = time component of 4-momentum

I knew this would only be a matter of time before you made this
mistake.

Is that a sentence?

Now you're back to the wavelength associated with a particle
again. Such a wavelength has no meaning other than in a statistical
sense.


I gave you the meaning, dunce. It's the range of the interaction.
