- Seattle Neighborhoods: Crown Hill — Thumbnail History (historylink.org)
The north Ballard neighborhood of Crown Hill sits on a gentle rise of land stretching from NW 75th Street to NW 100th Street and is bordered by the Loyal Heights neighborhood to the west and Greenwood to the east. Although the Seattle community has no town center, its commercial crossroads meet at 15th Avenue NW and NW 85th Street and follow northeastward along Holman Road NW, named after realtor Axel Holman, who platted the Sunset Hill area in the Loyal Heights neighborhood. When Ballard city residents voted to annex their town to Seattle in 1907, Crown Hill was still blanketed by Western red cedar, Douglas-fir, and Western hemlock conifers. Few settlers had ventured into the area, even though most of the land was now platted for residential development. Over the next nine decades growth in this quiet Ballard suburb was slow at first, then exploded during the World War II era. Today Crown Hill is home to more than 7,000 residents.

But how can we make this idea precise and quantitative? To focus the discussion I decided to tackle a specific puzzle: why does hydrogen gas at room temperature and pressure have an entropy corresponding to about 23 unknown bits of information per molecule?
