Back to basics...

Astrophysics is an very interesting subject to me. Within so many branches, Cosmology is really like a supernova all these years. After I got into college, nearly most of my astrophysics knowledge was growing towards Cosmology. Yes, Cosmology is indeed a vast subject that touches particle physics to general relativity and even string theory. However, astrophysics is not just about cosmology, not just about those big questions of our Universe. When I was visiting a school during my 3rd year of college, I worked in a group of observational cosmology. I was surprised that knowledge of statistics, basic physics about radiation absorption, emission are also very important. Recently, I have been reading Frank Shu's book, Gas Dynamics which contains so much about fluid mechanics, turbulence etc. These are all very important to study about stars and gases. Maybe sometime we do need to stop thinking about those dark energy, dark matter, and spend more time to understand our stars at an even deeper level.
