Purchasers can download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1902 Excerpt: ...earth. r' = radius of moon, or other body. P = moon's horizontal parallax = earth's angular semidiameter as seen from the moon. f = moon's angular semidiameter. Now = P (in circular measure), r'-r = r (in circular measure);.'. r: r':: P: P', or (radius of earth): (radios of moon):: (moon's parallax): (moon's semidiameter). Examples. 1. Taking the moon's horizontal parallax as 57', and its angular diameter as 32', find its radius in miles, assuming the earth's radius to be 4000 miles. Here moon's semidiameter = 16';.-. 4000::: 57': 16';.-. r = 400 16 = 1123 miles. 2. The sun's horizontal parallax being 8"8, and his angular diameter 32V find his diameter in miles. ' Am. 872,727 miles. 3. The synodic period of Venus being 584 days, find the angle gained in each minute of time on the earth round the sun as centre. Am. l"-54 per minute. 4. Find the angular velocity with which Venus crosses the sun's disc, assuming the distances of Venus and the earth from the sun are as 7 to 10, as given by Bode's Law. Since (fig. 50) S V: VA:: 7: 3. But Srhas a relative angular velocity round the sun of l"-54 per minute (see Example 3); therefore, the relative angular velocity of A V round A is greater than this in the ratio of 7: 3, which gives an approximate result of 3"-6 per minute, the true rate being about 4" per minute. Annual ParaUax. 95. We have already seen that no displacement of the observer due to a change of position on the earth's surface could apparently affect the direction of a fixed star. However, as the earth in its annual motion describes an orbit of about 92 million miles radius round the sun, the different positions in space from which an observer views the fixed stars from time to time throughout the year must be separated ...

Download or read book San Diego in the 1930s written by Federal Writers' Project of the Works Progress Administration of Northern California and published by Univ of California Press. This book was released on 2013-04-16 with total page 160 pages. Available in PDF, EPUB and Kindle. Book excerpt: San Diego in the 1930s offers a lively account of the city’s culture, roadside attractions, and history—from the days of the Spanish missions to the pre-Second World War boom. The guide is revealing both in the opinions it embodies and in the juicy details it records—tidbits such as the bloodiest and most incompetently fought battle of the Mexican-American War, Emma Goldman’s abruptly terminated speech to local Wobblies in 1912, and even a delightfully anachronistic way to beat a San Diego speeding ticket. Brimming with tours that can prove challenging to retrace, this book reminds us of the changes wrought by seven decades of intervening war, peace, and biotechnology. Unlatching a remarkable trapdoor into the past, this compact and charming document of the Depression era invites repeated browsing and is generously illustrated with striking black-and-white photographs that bring the period to life.
