¶ Javelin
Cross Reference
There were angular relationships here and it was possible to get the resultants. I liked what he /Galileo/ was doing and I liked the idea of the vector because it seemed to me just as a boy-- I’m standing in the water and I take an oar and I plunge it in the water and the thing comes back. There is something about the javelin having much more directional stability than the baseball. There is something man learned about an arrow and a sphere-- of its controllability compared to just the ball.
