Main approach to the problem of utilization of solar energy has been study of green plants, which in their own simple and mysterious way utilize the energy of sunlight to convert carbon dioxide and water into food. Chief agent in this process of photosynthesis is chlorophyll, the green coloring-matter in leaves, which acts as a catalyst, speeding up the transformation, but undergoing no conversion itself. Since chlorophyll is not effective as a catalyst when extracted from the plant, chemists have been unable to study its action. It is composed of two separate pigments, blue-green chlorophyll A and yellow...
...dark river is the monster planet Jupiter now shining in the southeastern sky. Three hundred times larger than the earth, containing more matter than all the other planets combined, Jupiter takes twelve years to complete its ponderous revolution around the sun. Far from the centre of the solar system, Jupiter receives little heat, has a small core of solid rock, surrounded by a frozen ocean, thousands of fathoms deep. Thick clouds hide from astronomers the furious storms that rack the planet, scarring its face with wide bands of purple, red and brown...
...star reported last week is so far away that it is not even in the Milky Way galaxy, 600 quadrillion miles in diameter, to which the solar system and all stars visible to the naked eye belong. In it the neutrons are so closely packed, according to Zwicky, that the density reaches the enormous figure of 6,000,000 tons to the cubic inch. Since the General Theory of Relativity imposes limits on stellar masses, Zwicky's new star must be exceedingly small to compensate for its high density. The astronomer estimates its diameter at no more than...
...Solar radiation is the primary cause of ionization in this upper atmosphere, and changes in sun light caused by sunrise, sunset, sunspots, eclipses, or other phenomena, affect the blankets markedly. Harvard sent expeditions to New Hampshire in 1932 and to Russia in 1936 to study the effects of solar eclipse on the ionosphere...
Last week Massachusetts Institute of Technology, where Mr. Cabot studied before he entered Harvard, announced that it had received from him a gift of $647,700 for a research program to investigate the direct methods of harnessing solar power -mechanical, electrical, chemical. Far from being floored by the prospect of such an enterprise, M. I. T.'s President Karl Taylor Compton feels that the Institute is well equipped to carry it out. Said he: "Mr. Cabot's generous gift makes it possible for the Institute to begin a great research program in which the combined efforts of scientists...
