That's for sure. Please point this out to your instructor.

Luckily I was able to get an international version for $20, I feel for those who bought it from the bookstore for $176. I have another question...
This is the author's formula and explanation of time dilation...
[itex] t = \frac{t_0}{\sqrt{1\frac{v^2}{c^2}}}[/itex]
t0 = rest clock
t = moving clock
c = speed of light
v = speed of clock in motion
An Amazon review says that he has definitions of t and t_0 backwards, is this true?
