A couple with three children waited in line at San Francisco's Pier 41 to purchase tickets for a boat trip to Alcatraz. Others watched with varying degrees of sympathy and irritation as the young children fidgeted, whined, and punched one another. The frazzled parents reprimanded them to no avail.
Finally they reached the ticket window. "Five tickets, please," the father said, "Two round trip, three one way."
X-ray moviesIn 1936, the success in making of X-ray moving pictures of internal organs of the human body was reported at the 37th annual meeting of the American Roentgen Ray Society in Cleveland by Drs William H. Stewart, William J. Hoffman and Francis H. Ghiselin from the Manhattan, NY, Lenox Hill Hospital. They used a home 16-mm camera to film moving X-ray images on a fluorescopic screen at 16 frames per second (reduced to 12 or 8 fps for thicker bodies). Two seconds exposure could capture two or three beats of the heart, the act of breathing, movements of the diaphragm or motion of joints. Film clip loops could be projected to show repeating motion. Movies were shown at the next convention on 2 Oct 1937.« |
