This was a special series of nine films created between 1956 and 1964 by Bell Telephone / AT&T corporation. These were crafted with entertaining animation and storylines that presented complex science theory in a clever way. Director Frank Capra wrote the screenplay for “Our Mr. Sun” with help from a scientific advisory board. (Donald Menzel's book titled “Our Sun” published in 1949, was also used.) This feature takes a look at our Sun, the physics of how it works, and its effect on the Earth. Possibilities for utilizing solar energy are explored, the spectroheliograph is put to use and the Sun’s historical as well as mythological significance to ancient civilizations are relayed. (00:00) Bell Telephone and Telegraph logo and the title screen (:34). Credits: starring actors Eddie Albert and Lionel Barrymore (:40). A dialogue begins between a fictional scientist and writer about the birth of the Sun (1:07). Personified characters including Father Time and Mr. Sun are introduced (1:54) behind a “curtain of imagination.” It begins with mythological understandings (4:03); various scenes in nature awake to the sun (4:31). The Sun announces himself as a star (4:59) over images of stars in the galaxy. Early civilizations believed the sun was a God and constructed numerous temples to honor these God’s (5:46). The Greek’s honored Apollo (6:12). Anaxagoras (6:35) first contested these ideas. Though he was exiled; his theories spread (7:08). Mythological curiosity lead to scientific understanding; modern observatory domes (7:20) were erected replacing temples and hymns. Charts track the sun’s operations (7:22). Maps show the orbital path of the sun (7:30). A corn farmer spills yellow seeds (8:51) as Mr. Sun reminds viewers his necessity for life. Distance of the sun in relation to earth (10:47) as well as relation to another star (10:57) Alpha Centauri follows. Viewers learn the diameter (11:18), weight (11:18) and composition of the sun (11:33); a hot gaseous blend of hydrogen and helium. Temperatures within and on the outer rim of the sun (12:26) are relayed. Images follow of the moon passing in front of the sun (12:55) in a total eclipse. Scientists of National Geographic seek to understand the Sun’s corona (13:00), dragging various instrumentation around the globe to capture eclipses. Images captured are pictured (13:31). Dr. George Ellery Hale (14:32) and Henri-Alexandre Deslandres (14:35) invented the spectroheliograph (14:40). White light pictures of the sun (14:52) are compared to images collected from the spectroheliograph (14:57). Other images are captured using violet light from incandescent calcium atoms (15:11). Dr. Robert R. McMath (15:19) is pictured at work in the McMath-Hulbert Solar Observatory in Lake Angelus, Michigan. First-time lapsed motion pictures of details on the face of the Sun. Astronomers at the Mount Wilson Observatory (15:35) look at sunspots. Fluctuation in temperatures (16:49) over the years are relayed by chart. The significant discovery the equator rotates faster than the poles is explained (17:11). Dr. Bernard Lyot of France operates the coronagraph (18:05). Modern versions (18:19) at the High-Altitude Observatory at Climax Colorado under direction of Dr. Walter Roberts (18:23). Air Force Installation at Sacramento, New Mexico (18:27). Dr. Donald H. Menzel (18:34) of Harvard was the first American to use the coronagraph. Red hydrogen coronagraph motion pictures follow (18:40). Prominences (19:13) and coronal rain are photographed (20:14). Images collected on June 4th 1946 (20:28) captured an arch expanding out of range of instruments at Climax Observatory. Radio astronomy in Australia with Dr. E. G. Bowen (21:26) captured distant radio waves (21:37). Images of aurora borealis follow (23:01). Ultraviolent rays and their effects on radio transmissions are explained (24:42). Sacramento Peak Observatory (SPO), also known as the Air Force Observatory at Sacramento (25:46) and other observatory sites maintain watch on the Sun. Warnings about severe magnetic storms (26:25). Potential use of solar energy (27:04) If you have endangered films you'd like to have scanned, or wish to donate celluloid to Periscope Film so that we can share them with the world, we'd love to hear from you.
