1. Mathematical physics finds its scientific origins in the study of celestial mechanics . 2. Cantelli's early papers were on problems in astronomy and celestial mechanics . 3. He wrote the book " A Guide to Celestial Mechanics " in 1961. 4. He wrote a monograph about celestial mechanics and a textbook of differential equations. 5. Celestial mechanics uses more general rules applicable to a wider variety of situations.6. He successfully used this approach to problems in celestial mechanics and mathematical physics. 7. Attending lectures by Istv�n F�ldes raised his interest in celestial mechanics . 8. Astrometric measurements are used by astrophysicists to constrain certain models in celestial mechanics . 9. Below we consider a circular orbit in astrodynamics or celestial mechanics under standard assumptions. 10. He worked on celestial mechanics , and orbits of comets and minor planets in particular.
