? - 13.01.1641, ТОКСТЕТ-ПАРК БЛИЗ ЛИВЕРПУЛЯ АНГЛИЯ


Английский астроном. Родился около 1618-19. В 1632-35 учился в колледже Эммануэля в Кембридже. Затем работал домашним учителем в Токстет-Парке и в Хуле, небольших деревнях близ Ливерпуля. Самостоятельно познакомился с основными астрономическими трудами древности и своего времени.
За свою недолгую жизнь Хоррокс обращался ко многим проблемам астрономии. Он был неутомимым и старательным наблюдателем, стремившимся к наибольшей точности результатов. Исходя из представлений Кеплера, развил собственную динамическую модель с.с., согласно которой планеты всегда притягиваются к Солнцу и (вопреки воззрениям Кеплера) никогда не отталкиваются им. Хоррокс считал также, что планеты испытывают притяжение друг к другу и обладают притягательным воздействием на Солнце и лишь благодаря своей большой массе оно остается неподвижным. Пересмотрел "Рудольфовы таблицы" планетных движений Кеплера, исправил в них ошибки, улучшил точность, заново определил элементы орбит планет. Вычислил момент прохождения Венеры по диску Солнца и первым в истории астрономии наблюдал его 4.12.1639 г. Его оценка солнечного параллакса, сделанная на основе этого наблюдения была вполне реалистичной (14") по сравнению с принимавшейся до того оценки Аристарха Самосского -3'. Построил лунную теорию, применявшуюся до середины XVIII в. Открыл неправильности в движении Юпитера и Сатурна. Лишь в 1672-73 Лондонское королевское об-во издало его труды.
Его имя занесено на карту Луны.



1. Dates Born: Toxteth, near Liverpool, 1619 Some sources say 1618, on the basis of information (which is not conclusive) that Horrocks had passed his twenty-second birthday.
Died: Toxteth, 3 Jan. 1641
Dateinfo: Birth Uncertain
Lifespan: 22

2. Father
Occupation: Peasant/Small Farmer
The father was a small farmer.
Horrocks went to Cambridge as a sizar. He was impoverished all of his brief life. I think we have to say that the father was poor.

3. Nationality

Birth: English
Career: English
Death: English

4. Education
Schooling: Cambridge
Cambridge University, Emmanuel College, 1632-5; no degree.
By his own testimony Horrocks found no instruction in mathematics at Cambridge, and had to teach himself.

5. Religion
Affiliation: Calvinist The connection with Emmanuel certainly suggests a Puritan.

6. Scientific Disciplines Primary: Astronomy
Horrocks managed to obtain a small telescope. His observations convinced him that Lansberg's tables were incorrect. He accepted Kepler's elliptical orbits, and in working on the moon he applied an elliptical orbit to it and established that the line of apsides precessed, an effect which he ascribed to the influence of the sun.
Horrocks predicted and observed a transit of Venus in 1639, the first one ever observed, and from the observation he corrected the solar parallax, indicating a much greater distance of the sun than anyone before him had admitted.
He developed a celestial dynamics, related to Kepler's but not identical to it, which employed concepts from terrestrial dynamics.

7. Means of Support Primary: Church Life
Probably he held a curacy in Hoole, 1639-40. This information, itself uncertain, is all we known about his life after he left Cambridge.

8. Patronage
Type: None No evidence has been found. It is probable that the curacy in Hoole involved patronage, but we know nothing about it.

9. Technological Involvement
Type: Instruments
Apparently Horrocks made his own telescope, and he developed projection techniques that enabled him to view the sun.

10. Scientific Societies
Memberships: None Informal Connections: intimate friendship and correspondence with William Crabtree.

If you can get hold of Chapman, Three North Country Astronomers, it is by far the best.
