“Apparently I lack some particular perversion which today’s employer is seeking”*…

 

 

Instead of looking at only the most common job in each state, I found the top five for a slightly wider view. You still see the nationally popular occupations — drivers, cashiers, and retail workers — but after the first row, you see more regional and state-specific jobs.

The sore thumb in this picture is Washington, D.C., whose top five ordered by rank was lawyers, management analysts, administrative assistants, janitors, and, wait for it, chief executives…

As we struggle to add the gainful to employment, we might recall that it was on this date in 1870 that America’s first asphalt pavement was laid in front of City Hall in Newark, N.J.  Edmund J. DeSmedt, the Belgian chemist who oversaw the work, had received a U.S. patent for this asphalt paving method two months earlier. Later that year, DeSmedt became the inspector of asphalt and cements for the District of Columbia, and oversaw wide application there.

Fluid dynamics…

Coach: Can I draw you a beer, Norm?
Norm: No, I know what they look like. Just pour me one.

Readers may have recognized that your correspondent has a weakness for nifty info-graphics.  In browsing recently, he came across a wonderful series created by Wallstats for (Roughly Daily’s old favorite) Sloshspot

…and in that series, a striking juxtaposition.  Consider that:

And that, at the same time:

As we plan to monitor our water use and tithe from our beer allowances to RDI, we might recall that it was on this date in 1870 that Professor Edward Joseph De Smedt of the American Asphalt Pavement Company, New York City, received two patents for the invention known as “French asphalt pavement”–  the first practical version of sheet asphalt.  Later that same year (on July 29), the first road was paved with sheet asphalt: William Street in Newark, New Jersey.
