so this came up last night ... but i guess my question is what does it mean in scietific terms for the "wave function to collapse"?

for example a projectile weapon like an arrow is shot through the air, why is it said that at any given instance the arrow occupies only one space with a deffinite velocity rather than it occupies a set of possible states(positions) with a uncertain momentum?

the original idea was from this book exerpt:
i concluded that he may in fact not have been wrong using only logic. That the arrow could occupy two spots at infidesimal instances where a velocity and definite position are only verified upon observation of the instant.

arrows are big. the spread in the momentum and position is so small its unmeasurable.

>> No.4736815

The set would be continuous. Much harder to work.

>> No.4736821

Isn't its momentum, as well as it's velocity, constant?

Velocity, as well movement, is dependent upon time. If the time is frozen, the movement will also be frozen. You have to get a difference between spaces to find movement, as well as a difference between times, if at a single moment, the arrow occupies one space.

unmeasurable does not mean non-existant though

>> No.4736853

>>4736846
so if time is frozen the only thing that can be defined about the system is its energy values?

cool pseudoscience bro

>> No.4736858

what do you know about "collapse of the state vector or reduction of the wave packet"

>> No.4736863

along time ago there was someone who posted here about a greek phillosopher who posulated the theory of relativity mearly based on logic.

does anyone know who that was?

>> No.4736866

>>4736853

Yes, as well as it's position.

>> No.4736949

>>4736866
no.

>> No.4739053

we exist in a Newtonian world, the subatomic particles may exhibit quantum properties but n arrow is in one place at a time

Newtonian world = normal shit

>> No.4739060

The arrow isnt a particle-wave its a huge group of particle waves, all with varying energy, momentum, position, etc.
But, they all come together to average out, overlap, and become NEARLY constant
yes yes, there is uncertainty of its EXACT position and momentum, get over it
