This historic book may have numerous typos and missing text. 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 ...
Edward Lear was born in Holloway, England, to Jeremiah (a stockbroker) and Ann Lear, tutored at home by his sister, and briefly attended the Royal Academy schools. Both an author and an illustrator, he earned his living as an artist from the age of 15, mainly by doing landscapes. What he is remembered for is his nonsense books, especially his popularization of the limerick. Along with Lewis Carroll, he is considered to be the founder of nonsense poetry. In addition to his limericks, he created longer nonsense poems. The best---and best known---is The Jumblies, in which the title characters go to sea in a sieve; it is a brilliant, profound, silly, and sad expression of the need to leave the security of the known world and experience the wonder and danger of the unknown. His other most notable work is The Owl and the Pussy Cat, a less complex poem whose title characters also go to sea. Lear produced humorous alphabets and botany books as well. His wordplay, involving puns, neologisms, portmanteau words, and anticlimax, retains its vitality today and has influenced such contemporary writers of children's nonsense verse as Shel Silverstein, Ogden Nash, and Laura Richards
