The authors do a good job of describing the role on invariants in physics, and for that I am grateful.However the way the choose to simplify the math and science created more confusion for me than light.Their decision to not state the underlying formulas directly but instead to explain them in words required the authors to spread the formulas out over page after page making them unnecessarily difficult to follow. You cannot go back and review an equation because you can't find in buried in the text.Page 22 is a good example of unnecessary explanation. It requires the entire page to laboriously explain that x, y,and z are variables. (Do the authors really believe someone would buy a book with the title E=mc^2 if they did not understand the concept of a variable??)Minor point are belabored while major shifts are completely unexplained. For example, on page 80, the authors explain invariants in terms of the radius of a circle, all points on the circumference are equal (invariant) distance from the center. They explain that when this model is applied to space-time, it violates Cause and Effect. The explanation is enlightening; so far, so good. To fix the problem with cause and effect, the authors take a next step that is bizarre and unexplained. They change the Pythagorean formula to create a hyperbola and never explain how this new model of S/T maintains the invariance that was so obvious in the last model (the circle). Several commentators have noted this particular problem with book.Another example from page 131-3 is even more bizarre. After demonstrating that (gamma)MC (the scaling factor of S/T time) is conserved, they then state the (gamma)MC^2 is also conserved (Ok, I will take your word on that ...).
