We all understand that the position and momentum of a particle mustsatisfy
the Heisenberg Uncertainty Principle. But what does this mean? Isit
that _I_ can not know x & p with better precision? --- that theis
infinitesimal _particle_ "knows" exactly where it is and how fast it
going but an observer can not -- ie that the particle does indeedhave an
exact locations and velocity, but the observer just can't know what itis?
OR does it mean that the particle is of finite size such that ittakes up
a space of delta x?locations
Consider a particle in a 1 d box -- say of length L: How many
along L can the particle occupy? Assume any needed additionalinformation.
can the
Likewise, consider a 3 d box of sides L: how many places in the box
particle occupy?
Just me over here in my little corner.
