At the occasion of the edition of the new volume, PD Dr. Andreas Verdun (University of Berne) will give a public lecture on Leonhard Euler's methods of celestial mechanics.
Vol. 26 of Series II (Mechanics and astronomy) of Leonhard Euler’s Opera Omnia comprises eight of Euler's treatises on the theory of perturbations from the years 1763–1771 that turn on the movement of heavenly bodies about a central star modified by the effect of additional gravitational forces – such as the influence of Venus on the Earth's orbit, the interaction of Jupiter and Saturn and the three-body system formed by the Sun, the Earth and the Moon: this last issue was of great practical importance for navigation. They allow us to gain insights into Euler's approach to problems of celestial mechanics, a central field of work during all his life.
The editors of the volume, the editorial board of Series I–III, the Euler Committee of the Swiss Academy of Science (SCNAT), the publishers at Birkhäuser Science, the Departments of Physics and Mathematics/Computer Science as well as the Bernoulli-Euler Centre at the University of Basel plan to celebrate this occasion by a public presentation with a lecture by editor PD Dr. Andreas Verdun (University of Berne), followed by an aperitif.
