...ripe human ovum with a pinhead gives an inadequate concept of the true size of this interesting cell. Actually its diameter is but 1/200 in. This is about the size of the smallest grain of sand that could be seen with the unaided eye. Stated differently, a sphere having the diameter of a common pinhead (1/12 in.) possesses nearly 4,000 times the volume of a human egg. One can compute further that all the eggs needed to replace the present population of the world could be held in a derby hat, whereas the sperm to fertilize them would...
...tracks. At the headquarters of Old de Bono rumors were thicker than gnats. Some correspondents cabled that a camel corps of 20,000 men was being organized in the southwestern corner of Eritrea for a dash, not at any of the main Ethiopian positions but at Britain's "sphere of influence" in the general direction of Lake Tana...
...answer is simple; he must appeal to romance. Should he hire two thousand chorus girls headed by Sally Rand, Mae West, and Elaine Barry, a different spirit would pervade the dormitories. While they are leaders in education in a somewhat different sphere, they have played an important part in molding many a respectable Harvard...
...galaxy (the Milky Way) to the limits of the known universe. Dr. Hubble's longest looks into space have disclosed star-swarms 500,000,000 light-years away, and this appears to be the limit of Mt. Wilson's giant telescope. Thus the observable universe is a sphere about a billion light-years across. What Dr. Hubble calls a "preliminary reconnaissance" shows that the sphere probably contains 100,000,000 nebulae composed of stars, the average nebula being about 20,000,000,000 times as heavy as the Sun and shedding 85,000,000 times as much light...
...more in the northern sky than in the southern. This, however, turned out to be only a small-scale irregularity, tended to disappear when larger sky areas were polled, deeper penetrations into space made, the obscuring effect of dark matter allowed for. Now the galactic distribution in the observable sphere approaches uniformity. Dr. Hubble last week compared the population density to tennis balls 50 ft. apart. This he believes represents a dependable sample of the universe beyond the visible limits. The actual limits may never be reached except in the unlikely event that an instrument is built...
