- Bothell — Thumbnail History (historylink.org)
Loggers founded the King County community that became Bothell in the 1880s. After the trees were cut, Bothell became a farm community on the highway between Seattle and Everett. After World War II, the community grew into a suburb as homes took over the farms and dairy pastures. Between 1950 and 1992, the city expanded and the population multiplied 25 times. By the end of the twentieth century, Bothell reached out of King County and had become the third largest employment center in Snohomish County.
- Sierpiński triangle (Wikipedia)
The Sierpiński triangle, also called the Sierpiński gasket or Sierpiński sieve, is a fractal with the overall shape of an equilateral triangle, subdivided recursively into smaller equilateral triangles. Originally constructed as a curve, this is one of the basic examples of self-similar sets—that is, it is a mathematically generated pattern that is reproducible at any magnification or reduction. It is named after the Polish mathematician Wacław Sierpiński, but appeared as a decorative pattern many centuries before the work of Sierpiński.
