...best way to estimate the earth's overall albedo is to measure the brightness of "earthlight" on sunless parts of the moon, allowing for the earth's size and distance, and how much of its disk is in sunlight. Figured this way, the earth's albedo is about .40, which means that it reflects four-tenths of the sunlight that falls on it. It is dimmer than cloud-covered Venus (.64) but much brighter than the naked, rocky moon (.073). The brightness varies a good deal with the season, probably because of changes in the amount...
...wheel arrangement of 4-6-2, which, as an enthusiast knows, is the way you distinguish one steam engine from another. Others, like the two fellows who brought their tape recorders along, took special delight in 3713's whistle, which is marked for posterity on a commercial disk scheduled for release by Charles Clarke, an electronics specialist from Newton. Still others, such as the lady-folk, liked the aroma of the smoke, and the tingle of 3713's gorgeous soot.

Inside, there is maze of pulleys, levers, and chains and an aluminum disk about the size of a phonograph turn-table. It's really very simple, however...
...disk, the student places another disk containing sentences to be translated or numbers to add or whatever. These are made visible one by one through one of the windows when the lever is moved. At the same time, a strip of paper comes into reach on which the student writes his answer. When he presses the lever again, the answer slides under a piece of glass so that it is visible but cannot be changed while the correct answer appears in another window. If the student's answer is correct, he moves the lever which marks the paper as correct...
...very-old pros who stick close to Broadway-Cole Porter, Rodgers and Hammerstein, Harold Arlen, Frank Loesser, Irving Berlin, Johnny Mercer. But the million-dollar "pops" that feed the gluttony of the nation's 550,000 jukeboxes, slip through the hands of its several thousand disk jockeys, and shake the walls of dormitories and rumpus rooms are written for the most part by little-known men. They are more familiar to the Bureau of Internal Revenue, Income Tax Division, than to the public...
