- Grays Harbor County — Thumbnail History (historylink.org)
Grays Harbor County takes its name from the broad, shallow bay that drains five rivers in southwest Washington. The dense forests of spruce, hemlock, cedar, and Douglas fir attracted loggers and mill operators and at the turn of the twentieth century, communities such as Aberdeen, Hoquiam, Cosmopolis, and Montesano flourished. Immigrant wage earners flooded in to harvest green gold. One hundred years later, the county struggled to reinvent itself without logging, milling, and fishing. The Native Americans who were shoved aside by the settlers reemerged with self-government and new enterprises.
- 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).
