Hi guys,(adsbygoogle = window.adsbygoogle || []).push({});

I am in a class in intro physics and am having trouble fully understanding the theory of special relativity. A couple of "apparent" contradictions encountered in my textbook's explanations seem to be throwing me off. (These are based off the famous train example)

Observer 1: on track

Observer 2: on train

1) Observer 1 says that 2's clock goes slow, and observer 2 says that 1's clock goes slow.

2) Observer 1 says that 2's meter sticks are contracted along their direction of relative motion, and observer 2 says that 1's meter sticks are contracted.

These 2 observations seem to be contradictory. Can someone please explain to me why they are not?
