Oh, and the key to passing a math class is to do all your homework and more. Keep answering questions in the textbook until you understand the material completely. If you run out of questions (doubtful), find another source and do those.

When I first went back to school, I got a 55 on my first exam in Linear Algebra. At the time I was working nights in a wood production factory (5 PM to 3:30 AM, mon - fri). I was shocked, but buckled down, focused all that much harder, and scheduled time off work so that I could properly prepare...

Of course? Are you sure? I've yet to come across a model which expressed an overall structure to space-time which was not flat. Certainly it will not be flat everywhere, due to the presence of mass, but that's not what I mean by structure. Of course, my experience is still limited, so perhaps...

If we think of space in four dimensions, we model it as a 3-dimensional (flat) plane relative to the fourth dimension. GR has shown that gravity can be modeled as an indentation in this plane, where the indentation is proportional to the mass of the object. However, this indentation is...

Simple answer: no Long answer: Observations of galactic rotation tell us that one of three things is true: 1) More mass exists inside a galaxy than we can observe or 2) We do not understand gravity completely. or 3) Our model of the structure of space itself is wrong. We don't know...

and would like some input. I've defined myself as an astrophysicist for several years now, and it's been my dream to study astrophysics from early childhood. I went to university shortly after high school, but dropped out halfway during my second semester, largely because of depression and...
