These chapters develop and support the parallel pedagogy curriculum, as described in a May, 2017 *The Physics Teacher* publication. They are very short and simple with the intention that students will actually read them. Simple examples illustrate the concepts introduced, but the reader has access to many more examples and solutions via problem sets, exams and videos accessible from the class website from winter 2018. Please contact me if you find mistakes, have ideas for improvements, or want to contribute.
