"Celestial mechanics" nghĩa là gì?
21 Jun, 2023
"Celestial mechanics" -> nghĩa là một nhánh của thiên văn học nghiên cứu về chuyển động của các vật thể ngoài không gian; cơ học thiên thể.
Ví dụ
Detailed numerical tests focused on difficult high-precision gravitational (lực hấp dẫn) problems in astrodynamics (động lực học thiên văn) and celestial mechanics show how our general-purpose integrator is competitive with and often superior to state-of-the-art specialized symplectic and non-symplectic integrators in both speed and accuracy.
However, the celestial mechanics which determine (quyết định) how Earth and the other planets orbit the Sun are actually based on some well-established mathematical principles.
While planetary eccentricity (lệch tâm) may be a hard concept to get your head around, it is, nonetheless (tuy nhiên), an interesting topic, and just another amazing aspect of the integrated celestial mechanics that organizes our solar system and keeps it functioning like a well-oiled machine. Next week, we'll look at Kepler's Second Law of Planetary Motion.
The term celestial mechanics is sometimes assumed to refer only to the analysis (phân tích) developed for the motion of point mass particles moving under their mutual gravitational attractions, with emphasis on the general orbital motions of solar system bodies.
