Foreword

After 22 years of teaching, I have taught many courses and created many iterations of teaching materials. Some of this was “good” and some wasn’t. As the progeny of packrats, I saved a lot of these materials, even the garbage. Now, I have finally begun the process of culling this mess and this work-in-progress is the result.

My goal here is to transfer the stuff I feel is reasonable to an online text of sorts. But unlike most texts, this one will likely not be linear, nor perhaps coherent—at least across chapters. If it is useful to you; use whatever you want. If not, ignore it.
