Is the dominant hand a good indicator of the dominant hemisphere of the brain?

I would say no because a wide majority of people are right-handed. Although, I have never had a left-handed science teacher...still, it doesn't mean anything. From my experience (since i was very interested in this too), you can't tell which hemisphere one uses more if someone is right-handed, but more often than not, a left-handed person is usually right-brained (from what i can tell...ex: english teacher, history teacher, people who like art, etc.)
