  • Interesting fact: Boredom can lead to madness in parrots. When caged by themselves and neglected for long periods of time, these intelligent, sociable birds can easily become mentally ill. Many inflict wounds upon themselves, develop strange tics, and rip out their own feathers. The birds need constant interaction, affection, and mental stimulation; some bird authorities have determined that some parrot breeds have the mental abilities of a 5-year-old human child. Should a neglected parrot go mad, there is little that can be done to restore it to normalcy. In England, there are "mental institutions" for such unfortunate creatures.

In science:

Regarding eq. (7), it is important to note: being the distance-dependent, all the original interactions (the Coulomb interaction and the nuclear interaction in eq. (5)) transform into the “external fields” (the one-particle potentials V (ˆ~ρRi )) for the “relative particles” system R.

The particles in the RLPM interact via two types of interactions: a repulsive interaction vE between all pairs of particles (either direct or mediated via a solvent); and an attractive interaction vL between the pairs of particles that are chosen at random to be linked.
Soft random solids and their heterogeneous elasticity
When the interaction is weak compared to the bandwidth (or Fermi energy), it is standard to use the non-interacting limit as the reference point, and adopt the interaction normalized by the kinetic energy as a small parameter for perturbation theory.
