Gyroscope
The spinning gyroscope offers considerable resistance, depending on the angular momentum, to any torque which would change the direction of the axis of spin. ----Webster's New Collegiate Dictionary Flashing downhill on his bike My son stands on the seat, Then pedals through gears That raise the pitch Of rubber on asphalt To a high whine, Jerks both wheels upward In a bunnyhop, Rears the front pony-like In a wheelie, flirts The back wheel left And right in kickouts, Jumps the curb and Screeches to a halt Grinning, ``See, Mom?''
I see the years of falling off
And getting on again;
The world tilt;
The gyroscope spin.
