Through the Greeks and Arabs
Physics seemed to have flowed from early attempts to provide explanations that may have been Aristotelian. Please see the link.
Without physics, cars, TV's, and electric lights would not have been invented, we would not know about space and astronomy, we would never know about forces and atoms. Physics is about all that and more, which is why it is important. Without physics, we would not have computers or the internet.
Galileo Galilei has frequently been called the father of modern science. Galileo made many advances in the fields of astronomy and physics.
Well, there are really 2 types of astronomy; hobbyists who like to look at stuff in space from their back yards or observing sites and academic astronomers who study space. Recreational astronomy is important because it is fun and many asteroids and comets have been discovered that way. Academic astronomy has produced many great discoveries in physics which have helped improve technology, as well as it's often nice to explore beyond out planet for new things and get away from all our futile earthly problems.
Yes. There have been jobs in astronomy for as long as people can remember.
How does Astronomy involve Chemistry?There is actually quite a lot of Chemistry used in various areas of Astronomy.One big application is in the identification of spectral lines. Each element and molecule emits light at very specific frequencies, so we can use this fact to try to identify the composition of Astronomical objects from the light they emit. This can be hard, as there will be lots of things mixed in together all emitting different spectral lines (a famous astronomer once likened it to trying to reconstruct a piano from the noise it makes as it falls down the stairs!).Areas where chemistry is particularly important is in studies of our Solar System, where the bodies can have very interesting composition. Another area is looking at Molecular Clouds (clouds with molecules in them) from which it is believed that stars form.
Lunar astronomy ( focused on the Moon) Planetary astronomy, the planets, Galactic- and so on on the basis of Celestial bodies under study and observation. There is also Radio Astronomy, a stepchild of Radar in a sense.
Physics started out as Natural Philosphy then became Physical Science which then got shortened to Physics.
Alvar Nunez Cabeza de Vaca was well educated as befitted his status and would have been taught several languages, physics, geometry, mathematics, cartography and astronomy.
Astronomy
Astronautics and astronomy are two of the branches of space science. This deals with the study of everything that exists in the outer space. Astronomy and astronautics are composed of sub-categories.
Astronomy is based on science; laws and facts that have been held as true. In this sense, astronomy IS real.If the question is whether or not Astronomy is fabricated out of the wild imagination of a few intellectuals--the answer is no.If the question is whether or not we are 100% sure of everything we claim to know...the answer is no.
