We watched the Ken Burns PBS series last fall, and seeing and hearing Black ball players talking about the segregation and racism put a topic which had been theoretical up until that point, into a context that they could relate to, because they care so much about the sport and its heroes. Then there are the questions about what is really happening to the ball when it is hit. Why do certain pitches behave the way they do. There's a lot of stuff about spin and trajectory and velocity and bernouli effect and Newton's laws here. Mom has been learning physics along with the kids.
Baseball is full of geometry.
The diamond is really a perfect square, each side measuring 90 ft. Go ask Pythagoras. Neal likes to make model stadiums and prefers to make them to scale. He has learned how to measure angles and to use the calculator to determine the correct ratios etc. Neal also writes a lot of stories, and often includes some kind of baseball situation either as a main theme or peripherally.
