Archived from the original on Part V shows a different kind of clock, where the motion of the pendulum is circular, and the string unwinds from the evolute of a parabola. By using this site, you agree to the Terms of Use and Privacy Policy. Part 1 describes the work on clocks carried out by Huygens, and his attempts at the determination of longitude at sea.

You will find many familiar propositions here in an unfamiliar guise. Part IVA is a recipe for finding the centre of oscillation for a suspended shape. In the second part of the book, Huygens states three hypotheses on the motion of bodies.

Most of the first part is concerned with the making and testing of such clocks. From constrained fall to the concept of potential”. The motion of a body falling along a cycloid. One can understand why Huygens’ book made such an impression on his peers, including Newton. He uses these three rules to re-derive Galileo’s original study of falling bodies, based on clearer logical framework.

The Measurement of Time and of Longitude at Sea”. It is the first time the quantity that Euler later horolgoium the moment of inertia was investigated. The motion of falling bodies.

Acta Hispanica ad Medicinae Scientiarumque. This is an annotated translation of Huygens’ Horologium Oscillatoriumtaken from the ‘Gallica’ website of the French National Library from the Oeuvres of Huygens, this also includes a French translation of the latin text; here the latin text is inculded last, from my own transcription. The fourth part of the book is concerned with the study of the center of oscillation. Truly, a wonderful piece of work: This work also has the advantage of accessibility, and comes to you free of charge.

For example, most of the intuitive ideas about centripetal forces are presented here oscillarorium Part V. They are essentially the law of inertia and the law of composition of “motion”. Mathematical and methodological differences”.

This work deserves to be read by all physicists and mathematicians with an interest in physics. I am indebted both to the editors of Huygens’ works, and to the Oscillaotrium numerique 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. 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.

I reserve the right to publish this translated work in book or e-book form. 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.

From Wikipedia, the free encyclopedia. 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. 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.

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.

This page was last edited on 9 Octoberat I am indebted on several points to the translation of Richard J. XVI, ppby M. Some results are only quoted, unfortunately, but this work gives a real insight into the state of mathematics in the middle of the 17th century.

The evolutes and lengths of curves. The construction of another kind of clock, and the enunciation of some theorems on centrifugal force.

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. 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.

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. However, if you are oscillatorimu student, teacher, or just someone with an interest, you can copy part or all of the work for legitimate personal or educational use. Views Read Edit View history.

It must be stressed that this hogologium 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. One presumes that Huygens made use of such tools in his derivation, which remain hidden.

You can help Wikipedia by expanding it. Huygens is seen as the outstanding physicist of the pre-Newton age who pointed the way forwards.
