If you wish to send me a message, then click on horologiym name. The tautochronous behaviour of the cycloid curve is used as a means of correcting the erratic behaviour of pendulums on ships.

Ocsillatorium is seen as the outstanding physicist of the pre-Newton age who pointed the way forwards. From Wikipedia, the free encyclopedia. Archived from the original on It is the first time the quantity that Euler later called the moment of inertia was investigated. Scientific, Historical, Philosophical, and Educational Perspectives.

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. Horologium Oscillatorium The Pendulum Clock, or Geometrical demonstrations concerning the motion of pendula as applied to clocks. 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 oecillatorium in part IIB.


In the second part of the book, Huygens states three hypotheses on the motion of bodies. Mathematical and methodological differences”. You will find many familiar propositions here in an unfamiliar guise. One presumes that Huygens made use of such tools in his derivation, which remain hidden.

For example, most of the intuitive ideas about centripetal forces are presented here in Part V. I reserve the right to publish this translated work in book or e-book form. XVI, ppby M. Hoorlogium motion of a body falling along a cycloid. Truly, a wonderful piece of work: The derivations of propositions in this part is based on a single assumption: Click here for Concerning the Reasoning in Games of Chance.

The motion of falling bodies. 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: I am indebted both to the editors of Huygens’ works, and to the Bibliotheque numerique Concerning the centre of oscillation.

Blackwell, which I discovered only after most of my own translation; this admirable translation does not however include mathematical notes, apart oscilltaorium an introduction by H.


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. They are essentially the law of inertia and the law of composition of “motion”. 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.

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. You can help Wikipedia by expanding it.
