In saecula saeculorum

Something I learned recently – the longest unit of time in Ancient Rome was called the Saeculum. It was the period of time from the moment that something happened (for example the founding of a city), until the point in time when all people living at the first moment had died.

Standalone US Cities

Recently I had a random thought: why is it that some city articles on Wikipedia are called, for example, Nashville, Tennessee – while others are simply, Seattle or Dallas? Is Nashville simply not culturally significant enough to stand on its own, without the cumbersome state identifier?Wikipedia has extensive policy about the article names for geographical locations, among […]

America’s GDP Split

The map shows a 50-50 split of the Gross Domestic Product (GDP) of the United States. The GDP of the cyan area is equal to the GDP of the orange area. This would equate to $8.10 trillion for each colored half in the above map.

Snow Days

The lightest green says “any snow” but also includes merely the prediction of snow. Also, this is snow accumulation over 24 hours/overnight. In much of the Midwest and Great Plains, school closing often depends more on wind chill and temperature than on snow accumulation (“cold days”). Thus, this map may be misleading in those areas. Many jurisdictions in California and […]
