page 52, equation (27) on the righthandside: T_{mn} > T_{pq} 
page 65, We shall consider the dot products of V with the e_{1}'s > We shall consider the dot products of V with the e_{i}'s 
page 136, line 6: Z^{3} > X^{3} 
page 143, equation (28), denominator in the definition of cosine: 2i > 2. And at bottom of page 145: no i in the denominator of the sine. 
page 179, line 12: the trajectory with shortest proper time > the trajectory with smallest action. And line 18: to minimize the proper time > to minimize the action 
page 191, second paragraph from bottom, formula for the Lagrangian. Inside the square root, it should be simply d tau^{2}. See image 
page 192, equation 36. The one occurrence of $\dot{r}$, in the denominator, should be $\dot{r}^2$

pages 274275, figures 8, 9 and 10, slanted line on bottom right: U^{+} = 1 > U^{} = 1 
page 285, lines 6 and 7: The interior of the shell is the part of the curve to the right of the shell. > The interior of the shell is the part of the curve to the left of the shell. 
page 311, bottom line: T^{m0}=T^{m0} > T^{m0}=T^{0m}. And at top of page 312, connect T^{m0} with T^{m0} > connect T^{m0} with T^{0m} 
page 328, line 5 from bottom: But outside the solar Schwarzschild radius the geometry is exactly the same > But outside the solar radius the geometry is exactly the same. And line 3 from bottom: Far away from the Schwarzschild radius > Far away from the radius 
page 333, 1st sentence of second paragraph: Notice that neither the Ricci tensor nor the Riemann tensor have to be zero. > Notice that the Riemann tensor doesn't have to be zero.
