For example, most of the oscillatorium ideas about centripetal forces are presented here in Part V. If nothing else, it demonstrates the beauty of the analytical methods that were soon to appear. 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.
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. The tautochronous behaviour of the cycloid curve is used as a means of correcting the erratic behaviour of pendulums on ships. This work also has the horologiuk of accessibility, and comes to you free of charge. One can understand why Huygens’ book made such an impression on his peers, including Newton. The book is also known for its strangely worded dedication to Louis XIV.
Acta Hispanica ad Medicinae Scientiarumque. 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.
Archived from the original on He uses these three rules to re-derive Galileo’s original study of falling bodies, based on clearer logical framework. The fourth part of the book is concerned with the study of the center of oscillation.
This work deserves to be read by all physicists and mathematicians with an interest in physics. 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. 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.
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. Retrieved from ” https: Iowa State University Press. The Measurement of Time and of Longitude at Sea”.
In the second part of the book, Huygens states three hypotheses on the motion of bodies. I am indebted both to the editors of Huygens’ works, and to the Bibliotheque numerique They are essentially the law of inertia and the law of composition of “motion”.
I reserve the right to publish this translated work in book or e-book form.
This article about a physics -related book is a stub. 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. Most of the first part is concerned with the making and testing of such clocks.
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. From Wikipedia, the free encyclopedia.
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 construction of another kind of clock, and the enunciation of some theorems on centrifugal force. 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.
I am indebted on several points to the translation of Richard J. Views Read Edit View horolofium. This page was last edited on 9 Octoberat 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 pendulumhoroloigum of oscillation and its interchangeability with the pivot point, and the concept of moment of inertia.
Part IVB evaluates the centre of oscillation for many familiar shapes in two and three dimesions as canditates for the pendulum bob. Mathematical and methodological differences”.

XVI, ppby M. The later theorems oscillxtorium 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 IVA is a recipe for finding the centre of oscillation for a suspended shape.
The evolutes and lengths of curves. Concerning the centre of oscillation. Part 1 describes the work on clocks carried out by Huygens, and his attempts at the determination of longitude at sea.
Mahoney can be found on the web, which provides the analysis for oscillaatorium final theorems. 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.
Huygens is seen as the outstanding physicist of the pre-Newton age who pointed the way forwards.
