Hi,
Adiabatic, iosbaric and isochoric processes are good approximations for a lot of thermodynamic phenomena in every day life.
But the conditions for a process to be isothermal are so artificial that i have grave difficulties to fudge a story.
Are there any examples of thermal...
Hi,
isn't it a bit dangerous to claim that
\left[ x \cdot \left( \psi(x,t) \, \frac{\partial \psi^\ast (x,t)}{\partial x} + \psi^\ast(x,t) \, \frac{\partial \psi(x,t)}{\partial x} \right) \right]_{x=-\infty}^{x=\infty} = 0
for example?
Expressions like this one are often found in...
Hi,
i thought a while about the meaning of the following expression
\delta t \, \cdot \, \mathrm{div} \, \vec j_m(\vec r,t) \qquad \mathrm{with} \qquad \vec j_m(\vec r,t) = \rho_m(\vec r,t) \cdot \vec v(\vec r, t)
Does it indicates the mass, which is produced / annihilated in the Volume...
Hi,
i worked through several examples where the ground state energy of a particle in an arbitrary potential V(r) is estimated with Heisenberg's uncertainty relation.
In these examples they prepare the Hamiltonian for the particle. For example the Hamiltonian for a particle in a harmonic...
