8288-847: The first motions were performed most properly by the Globe itself, rectified to the present elevation by the help of a moveable Azimuth ; he projected the Globe upon the plane of the Horizon, and applied to it at the center, which was therein the Zenith , an Index with projected degrees, for the moveable Azimuth." This projection answered his search, but then he had to invent theorems, problems and methods to calculate sections and intersections of large circles, which he could not find by instruments, not having access to any of sufficient size. In this way he drew out his findings, presenting one example to Bishop Thomas Bilson (who had ordained him), and another, in about 1606, to
8400-675: The foundations of the British Empire via colonization of the Americas . The accession of James VI and I in 1603 resulted in the Union of the Crowns , with the Stuart dynasty ruling the kingdoms of England, Scotland and Ireland .

The House of Tudor ended with the death of Elizabeth I on 24 March 1603. James I ascended the throne of England and brought it into personal union with
8848-423: The method of employing it. Gunter required the use of a pair of dividers to lay off distances on his rule; Oughtred made the step of sliding two rules past each other to achieve the same ends. His original design of some time in the 1620s was for a circular slide rule ; but he was not the first into print with this idea, which was published by Delamain in 1630. The conventional design of a sliding middle section for
8960-578: The most famous mathematician of all Europe, Mr. William Oughtred, parson of Aldbury in Surry, was in danger of sequestration by the Committee of or for plundered ministers ; ( Ambo-dexters they were;) several inconsiderable articles were deposed and sworn against him, material enough to have sequestered him, but that, upon his day of hearing, I applied myself to Sir Bolstrode Whitlock , and all my own old friends, who in such numbers appeared in his behalf, that though

9744-411: The prior treatise to King Charles I . He went so far as to show his page-proofs to Oughtred as they were being prepared, and dismissed his objections, printing some derogatory comments aimed at Forster and Oughtred in his Foreword.

His early preoccupation was to find a portable instrument or dial by which to find the hour, he tried various contrivances, but never to his satisfaction.

Oughtred penned an approving testimonial, dated 16 October 1659, to the foot of the English abstract of The Cabal of
10864-694: The use of his important invention, the slide rule , a mechanical means of finding logarithmic results. Two of Oughtred's students, William Forster and Richard Delamaine the elder, are concerned with the story of this book.

He gave free instruction there to Richard Delamaine, whom he found to be too dependent on mathematical instruments to get

The work gained popularity around 15 years after it first appeared, as mathematics took
12096-568: Was recalled and there was a second period where the executive power lay with the Council of state.

Ashmole noted that he paid a visit to "Mr. Oughtred, the famous mathematician", on 15 September 1654, about three weeks after the Astrologers' Feast of that year. Oughtred expressed millenarian views to John Evelyn in 1655: "Came that renowned mathematician, Mr. Oughtred, to see me, I sending my coach to bring him to Wotton , being now very aged. Among other discourse, he told me he thought water to be
