From Wikipedia, the free encyclopedia.

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. 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 from an introduction by H. Huygens is seen as the outstanding physicist of the pre-Newton age who pointed the way forwards. Retrieved 14 November You can help Wikipedia by expanding it.

One can understand why Huygens’ book made such an impression on his peers, including Newton.

For example, most of the intuitive ideas about centripetal forces are presented here in Part V. 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 construction of another kind of clock, and the enunciation of some theorems on centrifugal force. This work deserves to be read by all physicists and horplogium with an interest in physics. Retrieved from ” https: Scientific, Historical, Philosophical, and Educational Perspectives.

The Measurement of Time and of Longitude at Sea”. Part IVB evaluates the centre of oscillation for many familiar shapes in two and three dimesions as canditates for the pendulum bob.


Acta Hispanica ad Medicinae Scientiarumque.

Views Read Edit View history. Part III is a rather wonderful essay on the properties of the Evolutes of Curves oscillatorim their lengths, starting with the cycloid, the parabola, and others derived from conic sections and higher order curves.

From constrained fall to the concept of potential”. If nothing else, it demonstrates the beauty of the analytical methods that were soon to appear. Mahoney can be found on the web, which provides the analysis for the final theorems.

The fourth oscillatorum of the book is concerned with the study of the center of oscillation. In the process, Kscillatorium 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 a student, teacher, or just someone with an interest, you can copy part or all of the work for legitimate personal or educational use.

Some results are only quoted, unfortunately, but this work gives osciillatorium real insight into the state of mathematics in the middle of the 17th century. Iowa State University Press. If you wish to send me oscillatodium message, then oscllatorium on my name. The derivations of propositions in this part is based on a single assumption: Part 1 describes the work on clocks carried out by Huygens, and his attempts at the determination of longitude at sea.

I reserve the right to publish this translated work in book or e-book form. They are essentially the law of inertia and the law of composition of “motion”. 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.

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 osscillatorium a theory of curves.


I am indebted on several points to the translation of Richard J. The tautochronous behaviour of the cycloid curve is used as a means of correcting the erratic behaviour of pendulums on ships.

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, oscillatroium it still deserves a place in the historical presentation of the subject as presented today in elementary physics text books. The motion of a body falling along a cycloid.

He uses these three rules to re-derive Galileo’s original study of falling bodies, based on clearer logical framework. I am indebted both to the editors of Huygens’ works, and to the Bibliotheque numerique This work also has the advantage of accessibility, and comes to you free of charge. Mathematical and methodological differences”.

Archived from the original on This article about a physics -related book is a stub. Most of the first part is concerned with the making and testing of such clocks. One presumes that Huygens made use of such tools in his derivation, which remain hidden.

XVI, ppby M. The motion of falling bodies. The book is also known for its strangely worded dedication to Louis XIV.
