I live every day like it's the last day of my life

@kevin_nealon:

I live every day like it's the last day of my life.

Every morning I wake up real early, and I spend maybe three hours on the phone making funeral arrangements.

U.S. Naval Observatory

In 1842, the U.S. Naval Observatory was authorised by an act of Congress, one of the oldest scientific agencies in the U.S. James Melville Gilliss (1811-1865) is considered its founder, who in 1842 he secured the Congressional appropriation for the Depot of Charts and Instruments (est. 1830) to become the Naval Observatory. Its primary task was to care for the Navy's charts, navigational instruments and chronometers, which were calibrated by timing the transit of stars across the meridian. Initially located at Foggy Bottom, the observatory moved in 1893 to its present facility in Washington, DC. Gillis visited Europe to procure instruments, and the books that formed the core of the Naval Observatory Library. Matthew Fontaine Maury was the first director, followed by Gillis (1861-65).«[Image: domed portion of Foggy Bottom building, showing mast on which a ball dropped at noon as a visual signalofthe time.
