Cassini, Jean Dominique, 1625-1712 (Italian astronomer)


Found in 6 Collections and/or Records:

A Prognostication concerning the Frost by Monsieur Cassini the French King's Astrologer, 1697

Identifier: Coll-33/Folio B [30]
Scope and Contents

A scurrilous pamphlet probably directed, according to Gregory's marginalia, at Flamsteed, by one "Charles Bernard Chirurgein".

Dates: 1697

Observ: Eclipsos Lunaris Oxon 19 Octr 1697 et [Mercury] in [the Sun] 24 Oct 1697, October 1697, with 2 apparently attached documents from 17041693

Identifier: Coll-33/Quarto A [28]
Scope and Contents Two straightforward records of planetary eclipses, but meant, on palaeographic evidence, to be kept with a draft and a fair copy of a subsequent Philosophical Transactions of the Royal Society article [Vol. XXIV, No. 293, for September-October 1704, p1704] about the Cassini curve, a model of how a periodic comet probably orbits. Folding and fading of these documents suggest that they were inserted not long after David Gregory generated his index of Quarto A (which he drew up around 1700)....
Dates: October 1697, with 2 apparently attached documents from 17041693

Observata et Dicta ... cum Huygeno Junio 1693, 30 June 1693

Identifier: Coll-33/Quarto A [14]
Scope and Contents

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.

Dates: 30 June 1693

On Cassini's orbit, 10 September 1704

Identifier: Coll-33/Folio E [050]
Scope and Contents

A draft, on the eve of the publication of the Astronomiae, of a discussion in proposition 8 of Cassini's orbit, an apparent compromise between the true and approximate systems.

Dates: 10 September 1704

Orbita Planetaria Cassiniana ab Auctore missa 1699, 1699

Identifier: Coll-33/Folio C [116]
Scope and Contents

Jacque Cassini met Gregory in Oxford in March 1699, and gave him this writeup of his father Jean Dominique's famous 1693 planetary orbit. This was the first Gregory had seen of it, and his excited notes append the foot of the document.

Applied physics, considering ships,...
