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 ...

About the author (2009)

Born August 9, 1631 into a wealthy Puritan family, John Dryden received an excellent education at Westminster School and Cambridge University. After a brief period in government, he turned his attention almost entirely to writing. Dryden was one of the first English writers to make his living strictly by writing, but this meant he had to cater to popular taste. His long career was astonishingly varied, and he turned his exceptional talents to almost all literary forms. Dryden dominated the entire Restoration period as a poet, playwright, and all-round man of letters. He was the third poet laureate of England. In his old age Dryden was virtually a literary "dictator" in England, with an immense influence on eighteenth-century poetry. His verse form and his brilliant satires became models for other poets, but they could rarely equal his standard. Dryden was also a master of "occasional" poetry - verse written for a specific person or special occasion. Like most poets of his time, Dryden saw poetry as a way of expressing ideas rather than emotions, which makes his poetry seem cool and impersonal to some modern readers. Dryden also wrote numerous plays that helped him make him one of the leading figures in the Restoration theatre. Today, however he is admired more for his influence on other writers than for his own works. He died on April 30, 1700 in London.
