I too had a quick look over it and by quick I mean lightning. The first topic I chose to look at was on angular momentum and was quickly laughing quite loudly (which didn't go down too well at work).

"Seems very simple, but it is wrong. In the equation v = 2πr/t, the velocity is not a linear velocity. Linear velocity is linear, by the equation x/t. It is a straight-line vector. But 2πr/t curves; it is not linear. The value 2πr is the circumference of the circle, which is a curve."

Unfortunately for him, 2(pi)r is not a curve as the radius of a circle is constant. So the rest of his argument is pretty much useless. And if something as simple as a 3 constants producing a straight line screws with his mind, I dont even want to think what would happen if he tackled anything more complex...
