I am indebted both to the editors of Huygens’ works, and to the Bibliotheque numerique However, if you are a student, teacher, or just oscilatorium with an interest, you can copy part or all of the work for legitimate personal or educational use.

He uses these three rules to re-derive Galileo’s original study of falling bodies, based on clearer logical framework. This article about a mathematical publication is a stub.

Part IVB evaluates the centre of oscillation for many familiar shapes in two and three dimesions as canditates for the pendulum bob.

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 uorologium. Views Read Edit View history. 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 out in part IIB.

Huygens is seen as the outstanding physicist of the pre-Newton age who pointed the way forwards. Most of the first part is concerned with the making and testing of such clocks. The derivations of propositions in this part is based on a single assumption: 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. Retrieved 14 November XVI, ppby M.

Click here for Concerning the Reasoning in Games of Chance. This article about a physics -related book is a stub. The construction of another kind of clock, and the enunciation of some theorems on centrifugal force.

The book is also known for its strangely worded dedication to Louis XIV. The tautochronous behaviour of the cycloid curve is used as a means of correcting the erratic behaviour of pendulums on ships. Truly, a wonderful piece of work: You will find many familiar propositions here in an unfamiliar guise.

This work also has the advantage of accessibility, and comes to you free of charge. 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.

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. Archived from the original on If you wish to send me a message, then click on my name.

Mahoney can be found on the web, which provides the analysis for the final theorems. Part 1 describes the work on clocks carried out by Huygens, and his attempts osclilatorium the determination of longitude at sea. The fourth part of the book is concerned with the study of the center of oscillation.


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 work deserves to be read by all physicists and mathematicians with an interest oscillatoorium physics. The evolutes and lengths of curves. In the process, Huygens obtained solutions to dynamical problems such as the period of horplogium oscillating pendulum as well as a compound pendulumcenter of oscillation and its interchangeability with the pivot point, and the concept of moment of inertia.

The Horoloigum of Time and of Longitude at Sea”. The motion of a body falling hofologium a cycloid. 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. One can understand why Huygens’ book made such an impression on his peers, including Newton. From constrained fall to the concept of potential”.

It is the first time the quantity that Euler later called the moment of inertia was investigated.

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. I am indebted on several points to the translation of Richard J.

They are essentially the law of inertia and the law of composition of “motion”. Scientific, Historical, Philosophical, and Educational Perspectives. 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. One presumes that Huygens made use of such tools in his derivation, which remain hidden.
