- Bohr model (Wikipedia)
In atomic physics, the Bohr model or Rutherford–Bohr model is an obsolete model of the atom, presented by Niels Bohr and Ernest Rutherford in 1913. It consists of a small, dense nucleus surrounded by orbiting electrons. It is analogous to the structure of the Solar System, but with attraction provided by electrostatic force rather than gravity, and with the electron energies quantized (assuming only discrete values).

This is a climbing route (class 3 and 4) and not a trail, and should only be attempted by experienced climbers. There have been numerous search and rescue missions here.
