I really depends on where you put the 'how' and the 'why'.

Science is based on a system of posulate, that do not have
mathematical proofs. However, based on empirical observation, are
taken for granted.

For example, within SR, you may not ask why the speed of light is
constant in every frame of reference. This is an underlying posulate
of SR.

However, taking this granted, you may be abe to explain 'why'
travellers, moving close to light speed, will have their time slowed
down.

In Newtonian physics, you have to take m dv/dt = - d/dx V(x) for
granted. You cannot go anywhere by asking why this is true, within
Netwonian framework. You could conduct experiments and show this to be
consistant, however, you may not be to able to derive it. However,
from the schrodinger's equation or hisenberg mechanics, you will be
able to derive m d<v> /dt = - < d/dx V(x) >

I once got into debate witht this person, who got upset because i said
if you read David Griffits book, you will be able to understand
Quantum Mechanics.

He even quoted feyman saying 'nobody understands quantum mechanics.'
It's was interesting one of 2 ways. Feyman himself won the Noble Prize
in Physics, for QED. So, if he did not understand QM, did he get a
noble prize for plug and chugging? And feyman himself wrote many books
on QM.

So, it is important to put feyman statement into context. I really
think he meant to say, 'nobody understands why quantum mechanics is
the way it is.' However, his many books are on 'understanding how
quantum mechanics the way it is'.

Secondly, it is important to distinguish between 'rationale for things
the way they are' and 'reasons for things the way they are.'

Philosophers and Religions usually, indluge themselves over rationale
for things, not necessalirily reason for things.

Physics, and other sciences are more bent on reason for things. Their
reason for things have to agree with experiment, which something
philsophers rarely do.
