Understand Einstein and all of his contributions to science.
From the preface:
“For over two decades I have taught an introductory, undergraduate class, “Einstein for Everyone,” at the University of Pittsburgh to anyone interested enough to walk through door. The course is aimed at people who have a strong sense that what Einstein did changed everything. However they do not know enough physics to understand what he did and why it was so important.
The course presents just enough of Einstein’s physics to give students an independent sense of what he achieved and what he did not achieve. The latter is almost as important as the former. For almost everyone with some foundational axe to grind finds a way to argue that what Einstein did vindicates their view. They certainly cannot all be right.
Some independent understanding of Einstein’s physics is needed to separate the real insights from the never-ending hogwash that seems to rain down on us all.”
