Concerning the centre of oscillation. Most of the first part is concerned with the making and testing of such clocks.
The book is divided into five parts, where the first part contains the descriptions of clock designs, while the rest of the book is devoted to the analysis of pendulum motion and a theory of curves. If you wish to send me a message, then click on my name. Acta Hispanica horologiuk Medicinae Scientiarumque. You can help Wikipedia by expanding it. Blackwell, which I discovered only after most of my own translation; this admirable translation does not however include mathematical notes, apart from an introduction by H.
Huygens is seen as the outstanding physicist of the pre-Newton age who pointed the way forwards.
Archived from the original on It is the first time the quantity that Euler later called the moment of inertia was investigated. XVI, ppby M. Horologium Oscillatorium The Pendulum Clock, or Geometrical demonstrations concerning the motion of pendula as applied to clocks. From constrained fall to the concept of potential”. The evolutes and lengths of curves.
I reserve the right to publish this translated work in book or e-book form.
One presumes that Huygens made use of such tools in his derivation, which remain hidden. This article about a mathematical publication is a stub. The derivations of propositions in this part is based on a single assumption: However, if you are a student, teacher, or just someone with an interest, you can copy part or all of the work for legitimate personal or educational use.
Part 1 describes the work on clocks carried out by Huygens, and his attempts at the determination of longitude at sea.

He uses these three rules to re-derive Galileo’s original study of falling bodies, based on clearer logical oscillatorlum. Retrieved 14 November In the process, Huygens obtained solutions to dynamical problems such as the period of an oscillating pendulum as well as a compound pendulumcenter of oscillation and its interchangeability with the pivot point, and the concept of moment of inertia.
This work also has the advantage of accessibility, and comes to you free of charge. The construction of another kind of clock, and the enunciation of some theorems on centrifugal force.
They are essentially the law of inertia and the law of composition of “motion”. Retrieved from ” https: Huygens makes use of traditional Greek geometry and leans on Galileo in establishing the tautochronic behaviour of the cycloid, which is rather heavy going with such limited mathematical tools.
The book is also known for its strangely worded dedication to Louis XIV. From Wikipedia, the free encyclopedia. Part IVB evaluates the centre of oscillation for many familiar shapes in two and three dimesions as canditates for the pendulum bob. The tautochronous behaviour of the cycloid curve is used as a means of correcting the erratic behaviour of pendulums on ships.
This clock was presumably used to conduct experments on circular motion, and on the misnamed centrifugal force in particular, for which a number of theorems are set out without proof. This page was last edited on 9 Octoberat Scientific, Historical, Philosophical, and Educational Perspectives.
This work inspired a generation of physicists and mathematicians, including Newton, Johanne Bernoulli, and Euler, for it reaches far beyond the working of pendulum clocks, and it still deserves a place in the historical presentation of the subject as presented today in elementary physics text books. Part IVA is a recipe for finding the centre of oscillation for a suspended shape. It must be stressed that this present work is my own independent translation, in which I have gone through most of the relevant mathematics, and the Huygens scholar will of course be aware of Blackwell’s work as well as French and German translation.
The motion of falling bodies. The later theorems return to the clock, which is now standardised, and a use in determining a standard of length, as well as the acceleration of gravity, are investigated. I am indebted on several points to the translation of Richard J. Truly, a wonderful piece of work: Views Read Edit View history. Click here for Concerning the Reasoning in Games of Chance. The motion of a body falling along a cycloid. Part III is a rather wonderful essay on the properties of the Evolutes of Curves and their lengths, starting with the cycloid, the parabola, and others derived from conic sections and higher order curves.
For example, most of the intuitive ideas about centripetal forces are presented here in Part V. This article about a physics -related book is a stub. Mahoney can be found on the web, which provides the analysis for the final theorems. Part IIA relates to a careful geometrical examination of the speed and distance travelled by a body falling from rest in successive time intervals both vertically and down inclined planes; before embarking on motion down the cycloid curve, which is set out in part IIB.

The Measurement of Time and of Longitude at Sea”. I am indebted both to the editors of Huygens’ works, and to the Bibliotheque numerique You will find many familiar propositions here in an unfamiliar guise.
This is an annotated translation of Huygens’ Horologium Oscillatoriumtaken from the ‘Gallica’ website of the French National Library from the Oeuvres of Hlrologium, this also includes a French translation of the latin text; here the latin text is inculded last, from my own transcription.
Iowa State University Press. In the second part of the book, Huygens states three hypotheses on the motion of bodies.
