"Solar radiation" Quotes from Famous Books
 ... He proposed to investigate the effect of different elevations on the temperature of the dew-point; on the composition and electrical condition of the atmosphere, and on the rate and direction of the wind currents in it; on the earth's magnetism, and the solar spectrum; on sound, and on solar radiation. From 1862 to 1866 he made twenty-eight ascents, with Henry Coxwell as his balloonist. The most famous of these was from Wolverhampton on the 5th of September 1862, when Glaisher claimed to have reached a height of fully seven miles. After recording a height of 29,000 feet Glaisher swooned; ...

... more than 20,000,000 years old, and, of course, the earth is much younger. Both of these theories are quite generally accepted by scientists, and have much to support them. Prof. Young, of Princeton, in his Astronomy, p. 156, says, "The solar radiation can be accounted for on the hypothesis first proposed by Helmholtz, that the sun is shrinking slowly but continually. It is a matter of demonstration that an annual shrinkage of about 300 feet in the sun's diameter would liberate sufficient heat to keep up its radiation without ...

... but not in kind, we can obtain some idea of its quality from a knowledge of the velocity of radiation and of its possible intensity near the sun, in a manner applied long ago by Lord Kelvin (Trans. R. S. Edin. xxi. 1854). According to modern measurements the solar radiation imparts almost 3 gramme-calories of energy per minute per square centimetre at the distance of the earth, which is about 1.3X106 ergs per sec. per cm.2 The energy in sunlight per cubic cm. just outside the earth's atmosphere is therefore about 4X10-5 ergs; applying the law of inverse squares ...

... appear no more than a small star, the amount of heat which falls upon it from the great centre is enough each day to melt, if it all could be put to such work, about eight thousand cubic miles of ice. Yet the earth receives only 1/2,170,000,000 part of the solar radiation. The greater part of this solar heat—in fact, we may say nearly all of it—slips by the few and relatively small planets and ...
