Do particles, quarks, atoms really move in space, or is it field disturbance-wave that moves in S-T with speed $c$? How particles move in S-T in QFT? [closed]
As I understand particles are localized fields (16fields+g). Can you explain on hydrogen atom example that moves in space vacuum. Does it really moving, or it is continious field disturbance ...

How can we detect matter waves?
The DeBroglie wavelength associated with a moving object is $$\lambda = \frac hp$$
For an object of mass 200 grams traveling with a velocity 20 m/s, it is in the order of $10^{-34}$ m. Is current ...

Deriving $\mathrm d\omega/\mathrm dk = v$
I am reading Matter and Light by de Broglie and a little bit confused about how he deduced the equation of
$v_g := \frac{\mathrm d\omega}{\mathrm dk} = v$
I understand that a wave that is static in ...
