acromio rockxts Okay since both of you said the same thing tell me. Tell Me about space what are your favorite parts about it.
OH boy! Where do I even begin! Astronomy is the study of all objects and phenomena beyond the atmospheric boundaries of the Earth. Astrophysics is a subset of astronomy and physics concerned with the attributes that govern celestial objects. The differences between these disciplines were historically based on astronomy as an observational science, charged with the describing and cataloguing space, and astrophysics as a theoretical science; however, these differences are now largely semantic. Astronomers and astrophysicists today use a combination of observational and theoretical tools such as telescopes and analytical models.
Obviously, all of these sciences require a profound knowledge of mathematics. For example, the equations for the variation of the osculating elements of a satellite are integrated to yield the complete perturbations of the first order due to the second harmonic, together with the secular perturbations of the second order due to the second harmonic and of the first order due to the third to sixth harmonics. A set of smoothed elements is then derived, in which the perturbations of the even harmonics have no singularities, the semi-major axis and eccentricity have no variation due to the second harmonic and the other elements have the smallest possible amplitudes of oscillation.
