These notes are intended as an introductory course for experimental particle physicists interested in the recent developments in astrophysics and.

It was discovered that the black lines in the continuous spectrum of a star corresponded exactly to the emission lines of certain elements. Their presence in the star is suggested because those elements emit light of the same wavelength that is absorbed and hence, shows as a telltale black line.
It receives this light in a concentrated beam but emits it in all directions.
If you imagine the light rays as a 20 pack of javelins hitting an element in a certain place, the element will throw these javelins back out individually, into the surroundings so that the amount of light emitted in the direction of Earth is minute or non-existent, and hence we observe dark lines in the emission spectrum.
The Quantum Model of the Atom[ edit ] Quantum physics is a relatively new branch of physics that deals with very small objects, such as atoms and quarks. It follows different rules than classical or "Newtonian" physics.
While Newtonian physics assumes that energy can be continually divided and holds that an object can have an arbitrarily small amount of energy, quantum physics deals with objects that emit or absorb discrete packets of energy known as quanta that cannot be further divided. Classical physics assumes a continuum whereas quantum physics assumes the universe is discrete.
An introduction to astronomy and astrophysics
Max Planck is considered the "father of Quantum Theory". In , Danish physicist Niels Bohr used Ernest Rutherford's research on the atomic nucleus and Max Planck's quantum hypothesis to create a quantum theory of atoms. This theory stated that an atom's electrons move only in definite orbits. When a hydrogen atom receives a photon, it jumps to a higher orbit.
Niels Bohr's model of an atom. If you already own Death by Black Hole and Origins, save your money. You already have this entire book. Tyson infuses the subject with his usual dynamic enthusiasm and humor. The subject is not presented especially deep but it is useful for anyone wanting to get a better layman's understanding of the Big Bang weird stuff , dark matter weirder stuff , and dark energy way weirder stuff.
Tyson gives you a good appreciation of how chemistry and biology are part of astrophysics. He concludes with an essay on "Reflections on the Cosmic Perspective" that shows even astrophysicists can have great wonder at the universe we live in.
A good read By site Customer This book is made out to be an "astrophysics for dummies" but it's far more difficult to grasp than I'd imagined.
That being said, I'm still glad I read it.

The flow field can be approximated as a lead shock wave, followed by a self-similar subsonic flow field. In simpler terms, a blast wave is an area of pressure expanding supersonically outward from an explosive core.

Knowledge is your reward. The organization is driven more by physics than by astronomy; in other words, topics are first developed in physics and then applied to astronomical systems that can be investigated, rather than the other way around.
