Wow. Required reading to begin to get a grasp on electrical relationships of 1, Ψ, Φ, and Q. There is a couple pages of homework Dollard gives in the back of this book. Pick up a pencil and do your homework. He broached one topic- the integratron, I thought a tad strange, in such an important work- but the work and the book are his, not mine, so who am I to saw what should or should not be included? Easy, and fun to read- Dielectric induction described as tubes of force- related through analogy as spaghetti, all put into mathematical form. This book defines counterspace and counterspatial relationships as well, it makes a lot of sense when you pick up the vernacular.
