Here's the question that I mentioned in my introduction: If anyone can give me the answer, please keep it very simple - I was never any good at physics or higher math. It's very easy and only requires a claw-hammer to do. Very low tech. Hold the hammer at the end of the handle with the claw pointing to the right. Now flip it into the air having it do only one 360 degree turn. Catch it and notice where the claw is now. It's pointing to the left. Flip it once more and the claw points to the right. Why? Why does it twist when tossed? I'm not giving it any kind of twist when I toss it. That's my question, and it's been bothering me for years. Thanks for any help you can give me.
