In a 1716 issue of the Philosophical Transactions of the Royal Society, Edmund Halley illustrated Gregory's theory more fully and explained further how it could establish the distance between the Earth and the Sun. In his report, Halley suggested places that a full transit should be viewed due to a "cone of visibility".
1705 – Edmond Halley publicly predicts the periodicity of the comet of 1682 and computes its expected path of return in 1757. [102] 1715 – Edmond Halley calculates the shadow path of a solar eclipse. [103] 1716 – Edmond Halley suggests a high-precision measurement of the Sun-Earth distance by timing the transit of Venus. [104]
1716 – Edmund Halley suggests that aurorae are caused by "magnetic effluvia" moving along the Earth's magnetic field lines. Global circulation as described by Hadley. 1724 – Gabriel Fahrenheit creates reliable scale for measuring temperature with a mercury-type thermometer. [36]
[5] [6] A second method, proposed in 1663 by the Scottish mathematician James Gregory, [7] was promoted by Edmond Halley in a paper published in 1691 (revised 1716). [8] He demonstrated how the AU could be measured very accurately by comparing the duration of the Venus transit across the face of the Sun as measured by two observers spaced at ...
A total solar eclipse occurred on 3 May 1715. It was known as Halley's Eclipse, after Edmond Halley (1656–1742) who predicted this eclipse to within 4 minutes accuracy. . Halley observed the eclipse from London where the city of London enjoyed 3 minutes 33 seconds of tota
As Edmond Halley pointed out in 1717, "But since it would be needless to enquire exactly what longitude a ship is in, when that of the port to which she is bound is still unknown it were to be wisht that the princes of the earth would cause such observations to be made, in the ports and on the principal head-lands of their dominions, each for ...
Frézier's account of his travels in South America was published in Paris in 1716 [4] [5] [6] (2d ed., enlarged, 1732). It was published in England in 1717 as A Voyage to the South-Sea, And along the Coasts of Chili and Peru, In the Years 1712, 1713, and 1714, which included a supplement by Edmund Halley. A Dutch translation appeared in ...
