Here is where we chart a learning course. The starting point is somewhere near a highschool level education. If you're not there yet, fear not! The Khan Academy has a truly excellent set of online resources to get you there. In fact, they've got us pretty well covered for math, and we'll be able to go to them for a lot of our physics as well. I can't say enough good things about the Khan Academy. If you haven't been to their site recently, GO! So, back to our map: we'll take for granted at least some background in mathematical concepts like algebra and trigonometry.
Our goal is to get a grasp on the real meanings of modern physics . . . at whatever level of depth we choose. At a minimum, we'll want to know the true meaning of time and space as far as they have been revealed by relativity and quantum theory. And since this meaning isn't likely to agree with the intuition we develop in our everyday interactions with the world, we'll want to know how science arrived at our modern understanding.
We're going to break up our curriculum into multiple "years" (we'll call each one a "series," since you are free to go at your own pace) like a typical university physics program. Unlike such a physics program, however, this online course of study will not provide you supervision in a physical laboratory nor a series of experiments to perform; what we do here could be considered a good preparation for college study rather than a complete substitute for it.
We're also going to break the material up into individual course names like you might find at a university. In fact, we'll be borrowing many course names, numbers, and descriptions from the University of Washington course catalog. But rather than listing just the prerequisites of these courses, we will identify several learning objectives within each course and be more specific about the dependencies between each of these objectives. For example, preparing for a full thirdyear course may require a particular firstyear course, but there may still be many worthwhile objectives in the thirdyear course which do not depend on such prior learning. Whether you want to be able to crunch the numbers or you're just looking for the highlights, we'll try to map out the learning path.
As online resources are identified for each course, you will be able to click on the course numbers in the lefthand column below to see an annotated, organized list; as well as a more detailed breakdown of learning objectives and some otherwise helpful coaching hints.
Don't be put off by the complicatedsounding names and descriptions; we've totally got this! Read the detailed course descriptions (as available) and see what they're all about in simple terms.
