This condition, he found, obtains for periods of roughly 11,000 years, then lapses for an equal period while the southern hemisphere takes its turn. Confirmation of this astronomical hypothesis Dr. Antevs had last week in varves: layers of sediments deposited, one layer a year, by melting glaciers. The varves are light-tinted when glacial ice melts fast (hot summers), dark-tinted when it melts slowly (cool summers). Dr. Antevs counted and deciphered 35,000 varves, found a cycle of alternately cool & warm summers in close agreement with the Spitaler calculations...
...looks redder at sundown than at noon because its light traverses a thicker layer of air at evening and is scattered by more particles in the atmosphere. The light lost by scattering reappears as the blue of the sky. It exactly compensates for the redness of direct sunlight...
...general Professor Olsen and his research arsonists (George E. Ferguson, Leopold Scheflan) found three distinct layers of gases present in their burning room, "one at the ceiling, one on the floor, and an intermediate layer which consisted of more nearly pure air than either of the other two." A few moments of blaze, however, churns the layers together...
...likewise was lifted by hot air. It carried a lire grate beneath the open mouth of the bag to maintain the hot air supply. The Bonettes were commemorating that event, but their balloon relied on its original supply of hot air. At about 3,000 ft. it struck a layer of cold air, began to shrink and descend. That should have been the signal for King Louie to jump with his chute, but now he felt he must stay and look after the camera. Faster & faster the bag dropped until a ground wind caught it, dragged it across the town...
...blue and violet bands in his spectrographs. Other exposures showed red light in "surprising strength." More recent observations demonstrate that zodiacal light contains the entire spectrum from red to violet. The assumption is that "the strange light originates at some distance above the Earth's surface, in a layer of considerable thickness. The Earth's atmosphere is playing a considerable role in the production of these radiations." The light seems to be a transformation of sunlight (or starlight) rather than a reflection of sunlight. In any case astronomers, astrophysicists and meteorologists have a new concept of the atmosphere...
