Σελίδα 327 - Napier lord of Markinston, hath set my head and hands at work with his new and admirable logarithms. I hope to see him this summer, if it please God ; for I never saw a book which pleased me better, and made me more wonder.
Σελίδα 320 - ... by addition and subtraction, division by two, or division by three : which secret invention, being (as all other good things are) so much the better as it shall be the more common ; I thought good heretofore to set forth in Latine for the publique use of mathematicians.
Σελίδα 366 - Kepler's work, however, it may not be improper in this place to take notice of an erroneous property laid down by him in the appendix to the 27th prop...
Σελίδα 320 - ... Seeing there is nothing (right well-beloved Students of the Mathematics) that is so troublesome to mathematical practice, nor that doth more molest and hinder calculators, than the multiplications, divisions, square and cubical extractions of great numbers, which besides the tedious expense of time are for the most part subject to many slippery errors, I began therefore to consider in my mind by what certain and ready art I might remove those hindrances.
Σελίδα vi - ... +ex4 -(-,&c., when it converges very slowly ; the investigation of a general rule for extracting roots ; new methods for the roots of equations ; a demonstration of the truth of the binomial theorem in the case of fractional exponents; curious properties of the common section of a sphere and cone; the geometrical division of circles and ellipses into any number of parts that shall be equal both in area and in perimeter ; and, lastly, a copious and instructive tract relating to experiments and...
Σελίδα 431 - Now thefe rativncula are fb to be underflood as in a continued Scale of Proportionals infinite in Number between the two terms of the ratio, . which infinite Number of mean Proportionals is to that infinite Number of the like and equal...

Σελίδα 312 - tis said) to save the tedious multiplication and division in astronomical calculations. Neper being solicitous to know farther of him concerning this matter, he could give no other account of it, than that it was by proportionable numbers. Which hint Neper taking, he desired him at his return to call upon him again. Craig, after some weeks had passed, did so, and Neper then shewed him a rude draught of that he called ' Canon Mirabilis Logarithmorum.
Σελίδα 381 - The 10th chapter is employed in teaching how to find the logarithms of fractions, namely by subtracting the logarithm of the denominator from that of the numerator, then the logarithm of the fraction is the remainder...
Σελίδα 419 - ... practice of navigation, by Henry Bond, who mentions this property in an edition of Norwood's Epitome of Navigation, printed about 1645; and he again treats of it more fully in an edition of Gunter's works, printed in 1653, where he teaches, from this property, to resolve all the cases of Mercator's sailing by the logarithmic tangents, independent of the table of meridional parts. This analogy had only been found to be nearly true by trials, but not demonstrated to be a mathematical property....
