Found in 147 Collections and/or Records:
A Theoreme Concerning Dice, s.d.
A jotting on game theory.
Ad Cartesis Specia ... sectionibus Coni, 1680
Notes on Cartesian cone sections, written out during Gregory's stay in Rotterdam.
The item going before, also labelled 134, may actually be 133 (or part of it), which was supposed to have been a treatment by James Gregory on hyperbolae, nautical spirals, and other things. It treats of a hyperbola, at least. Its hand is not David's, but neither is it the hand of item C 136, in James' familiar hand.
Ad Jo: De Witt Elem: Curvarum, 1680
A demonstratio on one of de Witt's notes on Schooten's 1659 Latin edition of Descartes' Geometria. Unrelated jottings on reverse are in a hand other than Gregory's.
Ad Pag. 23. Geom: Cartes: Notula, 1680
A difficulty in Descartes, probably written up in Rotterdam.
Ad pag: 221. Newtoni Nota, May 1694
Gregory's attempt to work out corollary 2 to Newton's proposition 91, from book 1 of the Principia, which compared the ratio of the attraction of a sphere to that of a spheroid, using the integration of the square root of a trinomial.
Ad Philosophiam Neutoni Nota, 15 September 1693
For Gregory's Nota to Newton's Principia. One of several attempts (see C46, C60, and C63) to understand Newton's corollary 2 to proposition 91, book 1, which discovered the ratio of the attraction of a shpere to that of a spheroid, and involved the integration of the square root of a trinomial.
Adnotata et contenta quaedam in Actis Lipsicis, 1692
A record of interesting articles in the Acta between about 1681 and 1692.
Adnotata ... ex Newtone, May 1694
Notes of some of the consultations with Newton in Cambridge from the 4th to the 8th of May, 1694. The topics of those talks included astronomy, mechanics, physics and mathematics. The mathematical topics included conic radii, conjugates of curves, the polar coordinates of an orbit, and the form of the solid of least resistance.
Adnotata Phys: et Math: de Newtono 1698..., 1698
Thoughts on Newton's theory of the moon. Gregory notes Fatio's success in deriving the inverse square law, and Flamsteed's refusal to supply orbital data.
Aenigma Florentinum. Dav: Gregorii M.S. in Trans: Philos, 1694
One of three drafts of a paper to solve the famous problem of drawing in a hemispherical dome four apposing windows, so that, when these were removed, the remaining surface of the dome could be exactly measured.
