Johannes Kepler (born December 27, 1571, Weil der Stadt, Württemberg [Germany]—died November 15, 1630, Regensburg) German astronomer who discovered three major laws of planetary motion, conventionally designated as follows: (1) the planets move in elliptical orbits with the Sun at one focus; (2) the time necessary to traverse any arc of a planetary orbitis proportional to the area of the sector between the central body and that arc (the “area law”); and (3) there is an exact relationship between the squares of the planets’ periodic times and the cubes of their mean distances from the Sun (the “harmonic law”). Kepler himself did not call these discoveries “laws,” as would become customary after Isaac Newton derived them from a new and quite different set of general physical principles. He regarded them as celestial harmonies that reflected God’s design for the universe. Kepler’s discoveries turned Nicolaus Copernicus’s Sun-centred system into a dynamic universe, with the Sun actively pushing the planets around in noncircular orbits. And it was Kepler’s notion of a physical astronomy that fixed a new problematic for other important 17th-century world-system builders, the most famous of whom was Newton.

Created the first untouchables a generation before Ness. Oldfield was in charge of entire investigation nationwide. He recruited local, state, federal, and Pinkertons. Really the first national interagency collaboration.

What is an Obsession? DB ‘Dan’ Cooper has been a constant thought — question of mine for Decades. What happened?
D. B. Cooper, also known as Dan Cooper, was an unidentified man who hijacked Northwest Orient Airlines Flight 305, a Boeing 727 aircraft, in United States airspace on November 24, 1971. During the flight from Portland, Oregon, to Seattle, Washington, Cooper told a flight attendant he had a bomb, demanded $200,000 in ransom.
After releasing the passengers in Seattle, Cooper instructed the flight crew to refuel the aircraft and begin a second flight to Mexico City, with a refueling stop in Reno, Nevada. About thirty minutes after taking off from Seattle, Cooper opened the aircraft’s aft door, deployed the staircase, and parachuted into the night over southwestern Washington.
