“CE the ‘resultant of forces’-- the vector of the combined forces X, Y. Galileo’s ‘resultant of forces’ was wrong because two colliding ships do not waltz gaily east-northeast 12 miles together. Usually one of the ships goes ‘down’-- into the sea-- toward the center of Earth-- which multidirection vector was not in Galileo’s ‘plane’ geometry scheme. Nevertheless I found his vectorial diagram exciting. It suggested a comprehensive geometry consisting entirely of vectors. . . .”
