Found in 17 Collections and/or Records:
A paper of my own about the descent in a Cycloid printed in the Philosophical Transactions of the Royal Society in 1697, cFebruary 1697
A late draft of an elementary development of Christiaan Huygens' work on the cycloid, that finally appeared anonymously in the Philosophical Transactions of the Royal Society for February 1697 (nos 225, 424).
Apud Doctorem Ruyschium Amsterodami, 24 May 1693
De affirmanda parallaxi magni orbis, cogitatum Hugenii, June 1693
A transcription of Christiaan Huygen's argument that because stars' observed radii are so insensibly small, the diameter of the earth's orbit relative to the stars' position is also insensible, and thus the parallax measurement, which ought to prove or disprove the Copernican layout of the heavens, is useless.
Epist ad D. Hugenium..., 10 September 1693
Draft of a letter to Christiaan Huygens, in which Gregory follows up on his promise in Holland to send along his 'second method' of quadrature in detail.
Folio C, c1680-c1708
Index Chartarum in M.S. C. in folio, 1700
An index, in Gregory's hand, to the material he designated as Folio C.
Machinae, Hydrostaticae, et hydraulicae et Barascopium Hugen:, December 1680
Novelties seen and sketched by Gregory in Paris. The hydraulic machine caused a doll to fly inside a bottle.
Memoranda et observata in Batavia 1693 Maio, 17 May 1693
Observata et dicta apud D. Hugenium, 06 June 1693
Notes of a conversation in Holland with Christian Huygens, concerning an 'horologium' to show hours, months, years, and planetary positions. More general mention of the work of numerous other scientists: Notably, Huygens disputes the notion of John Bernoulli (James Bernoulli's younger brother) that the curve of an inflated sail is part-catenary and part-circle, and warns that Newton ought not to be 'deflected' into theology or chemistry.
Observata et Dicta ... cum Huygeno Junio 1693, 30 June 1693
Remarks en passant about library volumes in history and physics seen in Leiden. A longer passage follows: notes to a conversation with Christiaan Huygens, critiquing Sir Isaac Newton's notions of absolute motion and the propagation of light. Huygens also says that John Flamsteed ought to declare for the absolute speed of light, and that this should persuade Jean Dominique Cassini.
