...impressive as anybody along the way were the Chinese "of great leisure and extremely strong nerves," who, despite their screaming anti-Japanese" banners everywhere, treated her with unfailing courtesy. Her concluding thought was that the Chinese "seem to be likely to inherit the earth and go on forever, while the Japanese, Italians and other Latin peoples go neurotic and mad, followed by the English...
...major irregularity." But the savants at Cambridge reasoned that it must contain at least 35,000 galaxies not apparent on the photographs, and that such density is not a mere irregularity of distribution but a cosmic entity. Although the great cloud is 100,000,000 light-years from Earth, beyond the reach of all but the most powerful telescopes, it stretches across nearly one-fourth of the sky's arc from horizon to horizon...
...When the richest nation on earth permits seven million-nearly a third-of its school children to be taught by a quarter million teachers who receive less than $750 a year, and 30,000 poverty-stricken teachers who receive less than $450 a year, there is need for an awakening of civic pride in the discharge of obligations to children...
...amount of decomposition of radioactive material. "A very young iron meteorite," said Dr. Urry, "is 100,000,000 years old. The oldest is 2,900,000,000 years old." The last figure is just within the upper limit commonly given by geologists for the age of the earth and the solar system. Dr. Urry believes that iron meteorites are the debris of planets which have broken up within the last 100,000,000 years...
...Mars in winter and the darkening of the "canals" in summer (possible evidence of vegetation), astronomers have long been convinced that there is very little water on the "red planet." The amount of water vapor in the Martian atmosphere appears to be less than 5% of that on earth. It is difficult to measure the planet's water by spectrographic means because of spectrum lines caused by vapor in the Earth's air. Last spring Astronomers Walter Sydney Adams and Theodore Dunham Jr. of Mt. Wilson Observatory had a good chance to finesse this difficulty. Mars was then...
