Science is really not about looking up facts in an encyclopedia. It is a process that
extends what we know into the realm of the unexplored. This can be
exciting, certainly; to be able to sneak a peak at the Universe at its strange,
awesome, cosmic best. But it is very different from your run-of-the-mill
standard “textbook” idea of science. Science is a social, human endeavor.
And as human beings, we crave authenticity. We have seen the trappings of society, we act as if we have mastered technology, and yet we know that something is lacking. We have succumbed to the lure of Ebay, Facebook and Amazon (at least, I know I have!), and yet we remain unsatisfied at some primal level. It’s time to peel away the layers of glitzy imagery and use our machines to exploit their ultimate purpose: the capability to process large amounts of data with instructions that we provide, in order to test our ideas about how the Universe seems to behave. In short, to do Science. For the first time, it is possible for the interested student (and we are all students, especially those that have any claim to be considered “learned” , such as the instructor!) to have this experience on-line.
The subject matter for this course will be divided into two
broad components which will be interweaved in an interdisciplinary fashion. The first is a general introduction to the physics and astronomy
information you will need to understand basic phenomena that occur in the realm
of x-ray astrophysics; the second is the presentation of authentic satellite
data from various exciting types of x-ray sources, which you will analyze to
better understand the working of the high-energy Universe in which we live.
There are no prerequistes for this course, other than high-school mathematics
(algebra and trigonometry).
I hope you will enjoy your experience in "Analyzing the Universe".
Using publicly available data from NASA of actual satellite observations of astronomical x-ray sources, we explore some of the mysteries of the cosmos, including neutron stars, black holes, quasars and supernovae.
